Overview

Based on the frequency of the target cell, intra-RAT mobility management can be classified into intra-frequency mobility management and inter-frequency mobility management.

Issue 01 (2016-03-07)


6


2 Overview

2.1 Definition Intra-Frequency Mobility Management Intra-frequency mobility management is implemented by handovers between E-UTRAN cells using the same frequency. A network may use the same frequency in different cells, and therefore the eNodeB needs to support intra-frequency handovers within the network.

Inter-Frequency Mobility Management Inter-frequency mobility management is implemented by handovers between E-UTRAN cells using the different frequencies. A network may use different frequencies in different geographical areas, and therefore the eNodeB needs to support inter-frequency handovers within the network.

2.2 Benefits Intra-RAT mobility management in connected mode provides the following benefits: l

Ensures the continuity of radio network coverage and provides uninterrupted communication services for UEs.

l

Provides means to transfer UEs and supports flexible networking to meet operators' service steering and load balancing requirements.

2.3 Architecture For the network architecture for intra-RAT mobility management in connected mode, see Overview of Mobility Management in Connected Mode.

3.1 TDLBFD-00201801 Coverage Based Intra-frequency Handover Intra-frequency mobility management is implemented through only coverage-based intrafrequency handovers. This chapter describes the basic feature TDLBFD-00201801 Coverage Based Intra-frequency Handover. For details about the engineering guidelines for this feature, see 7.1 TDLBFD-00201801 Coverage Based Intra-frequency Handover. The coveragebased intra-frequency handover is enabled or disabled by the IntraFreqCoverHoSwitch option of the ENodeBAlgoSwitch.HoAlgoSwitch parameter. When the UE establishes a radio bearer, the eNodeB sends a Measurement Configuration message to the UE to instruct the UE to perform measurement. This message consists of intrafrequency measurement configurations, including event A3 and measurement objects. The eNodeB determines whether to trigger coverage-based intra-frequency handover based on event A3 in the measurement result.

Event A3 Event A3 indicates that the signal quality in a neighboring cell is better than that in the serving cell. When coverage-based intra-frequency handover is enabled, the eNodeB sends measurement configurations related to event A3 to the UE during UE radio bearer setup. The entering and leaving conditions of event A3 are shown in Figure 3-1 and Figure 3-2, respectively. For details about event A3, see section 5.5.4.4 "Event A3 (Neighbour becomes offset better than PCell)" in 3GPP TS 36.331 V10.1.0. l

Entering condition: Mn + Ofn + Ocn - Hys > Ms + Ofs + Ocs + Off After receiving an event A3 from a UE, the eNodeB makes handover decision based on the reported candidate cell list.

l

Leaving condition: Mn + Ofn + Ocn + Hys < Ms + Ofs + Ocs + Off If the leaving condition of event A3 is met, the UE no longer reports event A3.

Figure 3-1 Event A3 triggering condition

Issue 01 (2016-03-07)

Figure 3-2 Event A3 leaving condition

Table 3-1 describes the variables in the preceding formulas. Assume that both Hys and Off are set to 2 dB. The eNodeB detects that the signal quality in the source cell always drops rapidly and the signal quality in the target cell always rises quickly in a handover. To facilitate intra-frequency handovers, you can set Ocs to -1 dB for the serving cell and set Ocn to 1 dB for the target cell. Ofs and Ofn use the same value for an intra-frequency handover. Assume that they are set to 0 dB, then the entering condition of event A3 is as follows: Mn + 0 + 1 - 2 > Ms + 0 - 1 + 2. That is, event A3 can be triggered when the signal quality of the target cell is 2 dB higher than that of the serving cell. Table 3-1 Parameters related to event A3 Variables in the Formula

4 Inter-Frequency Mobility Management

Inter-Frequency Mobility Management

Inter-frequency mobility management can be implemented in different manners. This chapter describes the following features/functions: l

TDLBFD-00201802 Coverage Based Inter-frequency Handover

l

TDLBFD-00201805 Service Based Inter-frequency Handover

l

TDLBFD-00201804 Distance Based Inter-Frequency Handover

l

UL-quality-based inter-frequency handover

l

Frequency-priority-based inter-frequency handover

l

TDLOFD-001050 Mobility between TDD-LTE and FDD-LTE

The triggering condition for each feature or function is different, and the mobility management can mainly be divided into the following phases: 1.

Target cell/frequency selection For a measurement, the eNodeB generates a candidate cell list based on inter-RAT measurement results. For a blind redirection/blind handover, the eNodeB selects a blind handover target based on the blind handover priority or frequency priority of neighboring cells. During measurement or blind handover for VoLTE services, the eNodeB filters frequencies or cells under frequencies that do not allow VoLTE services. That is, frequencies or cells under frequencies with the EutranInterNFreq.VolteHoTargetInd parameter set to NOT_ALLOWED are filtered.

2.

Handover decision In the handover decision phase, the eNodeB checks the candidate cell list. Based on the check result, the eNodeB determines whether a handover needs to be initiated and, if so, to which cell the UE is to be handed over.

3.

Handover execution In the handover execution phase, the eNodeB controls the procedure of UE handover to the target cell. The redirection mode is selected only when blind event A2 is triggered in the coverage-based scenario or the UE does not support handover.

For details about the engineering guidelines for this feature, see 7.2 TDLBFD-00201802 Coverage Based Inter-frequency Handover. The coverage-based inter-frequency handover is enabled or disabled by the InterFreqCoverHoSwitch option of the CellHoParaCfg.CellHoAlgoSwitch parameter. During a coverage-based inter-frequency handover, measurements or blind redirection/blind handover can be triggered and stopped by different events, as shown in Table 4-1.

NOTE

l With preferential blind handover, the eNodeB preferentially performs coverage-based interfrequency handovers in a blind manner. That is, the eNodeB does not have to deliver events that trigger inter-frequency handover. The IfCoverPreBlindHoSwitch option of the CellHoParaCfg.CellHoAlgoSwitch parameter specifies whether to enable preferential blind handover. l After a UE accesses the network, the eNodeB checks whether there are suitable blind neighboring cells or frequencies and delivers event A2 for blind handover. After the event A2 is triggered, the eNodeB transfers the UE out of the serving cell through blind redirection to avoid service drop. The process is called emergent blind handover. The EmcInterFreqBlindHoSwitch option of the CellHoParaCfg.CellHoAlgoSwitch parameter specifies whether inter-frequency or inter-RAT redirection is used during emergent inter-frequency blind handover.

When the IfCoverPreBlindHoSwitch option of the CellHoParaCfg.CellHoAlgoSwitch parameter is deselected, the blind event A2 and measurement event A2 are delivered as follows: l

Issue 01 (2016-03-07)

If the UE is in RRC-connected mode, the eNodeB delivers both blind event A2 and measurement event A2. Figure 4-1 shows the selection of blind redirection and measurement-based handover. –

If the signal quality in the serving cell is lower than the specified threshold, the UE reports event A2 for inter-frequency measurement. After receiving the report, the eNodeB delivers an inter-frequency measurement configuration.

–

If the signal quality in the serving cell further deteriorates and the eNodeB does not perform a handover for the UE, the UE reports blind event A2. After receiving the report, the eNodeB considers that the serving cell can no longer provide services for the UE and performs a blind redirection.

l

In either of the following scenarios, the eNodeB delivers measurement configuration for only blind event A2: –

The InterFreqHoA2OptSwitch option of the ENodeBAlgoSwitch.HoSignalingOptSwitch parameter is selected, and the UE does not support inter-frequency measurements.

–

The configured event A2 threshold for inter-frequency measurements is less than or equal to blind event A2.

If no blind handover cell or frequency priority in connected mode is configured, the eNodeB does not deliver blind event A2.

When the blind handover switch is turned on and the signal quality in the serving cell is lower than the specified threshold, the UE reports event A2 for inter-frequency measurement. The eNodeB directly performs inter-frequency blind handover.

4.1.1 Triggering and Stopping of Inter-Frequency Measurement Inter-frequency measurements are triggered by event A2 and stopped by event A1. During a coverage-based inter-frequency handover, the sequence that the measurement configuration for events A1 and A2 is sent is controlled by the ReduceInvalidA1A2RptSigSwitch option of the ENodeBAlgoSwitch.HoSignalingOptSwitch parameter. Issue 01 (2016-03-07)


17



l

If the option is selected, the eNodeB sends measurement configuration for event A2 when the UE sets up an RRC connection, and sends measurement configuration for event A1 after it receives an event A2 from the UE. This reduces the reporting of invalid event A1. Figure 4-2 shows inter-frequency measurement based on event A4/A5. Figure 4-4 shows inter-frequency measurement based on event A3.

l

If the option is deselected, the eNodeB sends measurement configuration for both event A2 and event A1 when the UE sets up an RRC connection. Figure 4-3 shows interfrequency measurement based on event A4/A5. Figure 4-5 shows inter-frequency measurement based on event A3.

It is recommended that the ReduceInvalidA1A2RptSigSwitch option and the TrigQuanBothMeasOptSw option of the ENodeBAlgoSwitch.HoCommOptSwitch parameter be selected on the live network. When IntraRatHoComm.InterFreqHoA1A2TrigQuan is set to BOTH, as shown in Figure 4-2, the inter-frequency measurement procedure is as follows: During the triggering and stopping of measurements, RSRP- and RSRQ-based procedures are mutually independent. This prevents premature event A1 delivering and invalid event A1 reporting. In addition, this prevents the delivering of invalid event A1 contents. When an RSRP-triggered event A2 is received, RSRP-based measurement is triggered irrespective of whether there is RSRQ-based measurement. When RSRP-triggered event A1 is received, RSRP-based measurement is stopped.

InterRat A1A2 measurement trigger quantity

IntraRatHoComm.InterF reqHoA1A2TrigQuan

This is a common parameter for intraRAT handover and is set for each eNodeB. This parameter specifies the Ms type and triggering quantity for events A1 and A2.

A3 InterFreq A1A2 Measurement TrigQuan

IntraRatHoComm.A3Int erFreqHoA1A2TrigQuan

This is a common eNodeB-level parameter used for intra-RAT handovers. This parameter indicates whether RSRP or RSRQ is measured for events A1 and A2 that are used for inter-frequency handovers based on event A3.

Event A2 for Target-based Measurement Huawei eNodeBs allow different event A2 parameters to be set for target FDD and TDD frequencies so that coverage-based handovers can be preferentially triggered for FDD or TDD frequencies. The entering and leaving conditions of event A2 is as follows: l

Entering condition: Ms + Hys < Thresh If the entering condition is met, the UE reports an event A2. After receiving the event A2 report, the eNodeB delivers a measurement configuration to start inter-frequency measurement.

l

Leaving condition: Ms - Hys > Thresh If the leaving condition of event A2 is met, the UE no longer reports event A2.

The variables Ms and Hys for event A2 for target-based measurement are the same as those for event A2 for inter-frequency measurement. Table 4-5 lists the offset thresholds related to event A2 for target-based measurement.

The threshold for event A2 is the sum of the RSRP threshold and RSRP offset.

Only the RSRP threshold for event A2 is accompanied by an offset, while the RSRQ threshold for event A2 is not.

CnOperatorHoCf g.TddIfHoA2Thd RsrpOffset (eNodeB level) or CELLOPHOCF G.TddIfHoA2Thd RsrpOffset (cell level)

The eNodeB delivers measurement configurations for event A2 for target-based measurement as follows: l

If the FDD and TDD threshold offsets are set to different values, the eNodeB delivers two measurement configurations for events A2, with one corresponding to an FDD frequency and the other corresponding to a TDD frequency. After a UE reports an event A2 related to a frequency, the eNodeB delivers the measurement configuration of the related frequency.

l

If the FDD and TDD threshold offsets are set to the same value, the eNodeB delivers one measurement configuration for event A2, without distinguishing between the FDD and TDD frequencies. After a UE reports an event A2, the eNodeB delivers two measurement configurations, one for the FDD frequency and the other for the TDD frequency.

Pay attention to the following points related to event A2 for target-based measurement: l

If only either of the offset is set to -100, the inter-frequency measurement of an FDD or TDD frequency is not triggered.

l

If both offset values are set to -100, the effect is the same as those set to 0. In this case, the eNodeB sends an inter-frequency event A2, with the threshold set to the event A2 threshold value.

l

If the calculated RSRP threshold is lower than the protocol-specified minimum value, the protocol-specified minimum value is used as the RSRP threshold.

l

If the calculated RSRP threshold is higher than the protocol-specified maximum value, the protocol-specified maximum value is used as the RSRP threshold. When eNodeB- and cell-level threshold offset parameters coexist, the cell-level parameter is used as the actual value. It applies to the FDD and TDD co-site scenarios where FDD cell policies differ from TDD cell policies.

4.1.1.2 Event A1 Event A1 indicates that the signal quality of the serving cell is higher than a threshold. The entering and leaving conditions of event A1 are shown in Figure 4-7. For details about event A1, see section 5.5.4.2 "Event A1 (Serving becomes better than threshold)" in 3GPP TS 36.331 V10.1.0. l

Entering condition: Ms - Hys > Thresh When event A1 is triggered, the eNodeB receives an event A1 from the UE.

l

Leaving condition: Ms + Hys < Thresh When the leaving condition of event A1 is met, the eNodeB no longer reports event A1.

The variables in the formulas for event A1 are the same as those in the formulas for event A2. Thresholds related to event A1 also vary according to events that are used to trigger interfrequency handovers, as described in Table 4-6.

Issue 01 (2016-03-07)


29



NOTE

In a directional handover, the eNodeB specifies frequencies for the UE. During directional handover measurement, the eNodeB delivers only the highest-priority frequency to the UE.

The VoipMeasFreqPriSwitch option of the CellAlgoSwitch.MultiFreqPriControlSwitch parameter specifies the directional handover parameters for UE with voice bearers. The HO_USE_VOIP_FREQ_ALLOWED option of the CellStandardQci.QciAlgoSwitch parameter determines whether services of the UE with this QCI are treated as voice services. The PsMeasFreqPriSwitch option of the CellAlgoSwitch.MultiFreqPriControlSwitch parameter specifies the directional handover parameters for UE without voice bearers. l

l

When directional handover is activated, the eNodeB selects and delivers the highestpriority frequency to the UE. If the number of frequencies with the highest priority exceeds the maximum, the eNodeB randomly selects frequencies from these frequencies. –

The EutranInterNFreq.VoipPriority parameter indicates the frequency priority of UEs with voice bearers for directional handover.

–

The EutranInterNFreq.PsPriority parameter indicates the frequency priority of UEs without voice bearers for directional handover.

When directional handover is not activated, the eNodeB delivers frequencies for measurement based on the full specifications. The FixedMeasObjIDSwitch option of the CellAlgoSwitch.MultiFreqPriControlSwitch parameter specifies the frequency priority. The eNodeB selects the frequencies for measurement in descending order of frequency priority till the number of selected frequencies reaches the maximum. If a priority maps multiple frequencies and the number of frequencies for measurement exceeds the maximum when all these frequencies are selected, the eNodeB randomly selects frequencies with this priority till the number of selected priorities reaches the maximum. –

When this option is deselected, the frequency priority is determined by the EutranInterNFreq.ConnFreqPriority parameter. A larger value indicates a higher priority. The eNodeB selects the frequencies for measurement in descending order of frequency priority till the number of selected frequencies reaches the maximum.

–

When this option is selected, the frequency priority is determined by the EutranInterNFreq.MeasFreqPriority parameter. A larger value indicates a higher priority. The eNodeB sets measurement object IDs based on frequency priorities to control the UE's actual measurement priorities. This ensures that the UE preferentially reports the measurement reports on high-priority frequencies.

Measurement Cell Delivering The eNodeB delivers information about a cell for measurement only if the cell individual offset (CIO) of the cell is not set to the default value (0 dB). The measurement priority of a cell is determined by EutranInterFreqNCell.CellMeasPriority and EutranInterFreqNCell.CellIndividualOffset. For details about the maximum number of frequencies and the maximum number of neighboring cells, see Overview of Mobility Management in Connected Mode.

4.1.3 Inter-Frequency Handover Triggering When receiving event A2 that triggers inter-frequency measurement, the eNodeB sends related inter-frequency handover events. Coverage-based inter-frequency handovers can be Issue 01 (2016-03-07)

triggered by event A3, A4, or A5. The EutranInterNFreq.InterFreqHoEventType parameter specifies the event that triggers coverage-based inter-frequency handovers. NOTE

l When Thresh1 of event A5 is less than or equal to the threshold of blind event A2, the eNodeB does not deliver measurement configuration for event A5. l If carrier aggregation (CA) is enabled and the EutranInterNFreq.InterFreqHoEventType parameter is set to EventA4(EventA4), the eNodeB will send a measurement configuration for event A5 to trigger an inter-frequency measurement when a CA UE reports an event A2 in the primary serving cell (PCell). For details, see Carrier Aggregation.

The trigger quantity IntraRatHoComm.A3InterFreqHoA1A2TrigQuan or IntraRatHoComm.InterFreqHoA1A2TrigQuan affects event A2 reporting to the eNodeB: l

If the parameter is set to BOTH, two A2 events are reported, with one being RSRPbased and the other RSRQ-based. When the entering condition for either of the A2 events is met, the UE reports the A2 event.

l

If the parameter is set to RSRP or RSRQ, the UE reports an A2 event only when the entering condition for the related A2 event is met.

The reporting quantity IntraRatHoComm.IntraFreqHoA3RprtQuan or IntraRatHoComm.InterFreqHoA4RprtQuan affects events A3, A4, and A5 reporting and affects the eNodeB in determining whether the signal quality of neighboring cells meets the handover requirement: l

l

If the parameter is set to BOTH, both RSRP-based and RSRQ-based MRs are reported. –

For event A3, the eNodeB triggers a handover based on the trigger quantity configurations.

–

For event A4, the eNodeB triggers a handover only when event A4 is received and both measurement quantities meet the event conditions.

–

For event A5, the eNodeB triggers a handover only when event A5 is received and both Threshold 1 and Threshold 2 conditions are met. n

Threshold 1 condition of event A5 is met when the UE satisfies the RSRP or any RSRQ threshold.

n

Threshold 2 condition of event A5 is met when both measurement quantities meet the event conditions.

When this parameter is set to SAME_AS_TRIG_QUAN, the trigger type for interfrequency handover is the same as that for inter-frequency measurement. For example, if the trigger type for event A2 is RSRP, RSRP is used for event A3, A4, or A5 decision making. A handover is triggered after the related event is received.

4.1.3.1 Event A3 Event A3 triggers inter-frequency handovers the same way as it triggers intra-frequency handovers. For details, see 3.1 TDLBFD-00201801 Coverage Based Intra-frequency Handover. All parameters (other than Ofn and Off) for event A3 that triggers inter-frequency handovers are the same as those for event A3 that triggers intra-frequency handovers.

Triggering and Stopping When the UE reports event A2 for measurement and the IfCoverPreBlindHoSwitch option of the CellHoParaCfg.CellHoAlgoSwitch parameter is selected, the eNodeB triggers blind handover. If the eNodeB receives a report of event A1 for measurement from the UE before blind handover is completed, the eNodeB stops performing blind handover. When the UE reports blind event A2, the eNodeB triggers blind redirection. If the eNodeB receives the event while processing the handover, the eNodeB records the event. If the handover preparation fails, the eNodeB performs blind redirection. If the eNodeB receives blind event A1 reported by UE before the blind redirection is complete, the eNodeB stops blind redirection. When CellAlgoSwitch.VolteRedirectSwitch is turned on, blind redirection can be triggered for services with QCI of 1. In this case, the cause value in the release message sent from the eNodeB to the MME is the fixed value User Inactivity. Table 4-15 lists parameters related to blind events A1 and A2.

InterRat A1A2 measurement trigger quantity

InterRatHoComm.InterR atHoA1A2TrigQuan

This is a common parameter for interRAT handover and is set for each eNodeB. This parameter specifies the Ms type and triggering quantity for events A1 and A2.

Blind event A2 can be used to trigger both coverage-based inter-frequency blind redirection and inter-RAT blind handover. Coverage-based inter-frequency blind redirection and interRAT blind handover share the same thresholds related to event A2. The working principles for event A2 for coverage-based inter-frequency blind redirection and inter-RAT blind handover are similar. For details about blind event A2, see Inter-RAT Mobility Management in Connected Mode.

Target Selection The target selection priority for blind handover is specified by EutranInterFreqNCell.BlindHoPriority. If none of the neighboring cells are configured with the blind handover priority (EutranInterFreqNCell.BlindHoPriority is set to 0), the eNodeB performs measurement-based handover instead of blind handover. Figure 4-10 shows target selection process for blind redirection. l

The EutranInterFreqNCell.BlindHoPriority parameter specifies the blind handover priority.

l

The UtranInterNFreq.ConnFreqPriority parameter specifies the frequency priority for connected mode.

For a coverage-based blind redirection/blind handover, E-UTRAN TDD and E-UTRAN FDD are considered as two independent systems, and the CnOperatorHoCfg.FirstRatPri and CnOperatorHoCfg.SecondRatPri parameters specify the priorities of E-UTRAN TDD and E-UTRAN FDD. l

If the CnOperatorHoCfg.FirstRatPri parameter is set to EUTRAN, E-UTRAN TDD and E-UTRAN FDD are not prioritized.

l

If the CnOperatorHoCfg.SecondRatPri parameter is set to NULL, blind handover is performed only to frequencies of the network specified by the CnOperatorHoCfg.FirstRatPri parameter. If the operator-level parameter CnOperatorHoCfg.FirstRatPri and the cell-level parameter CellOpHoCfg.FirstRatPri coexist, the cell-level parameter is used as the actual value. It applies to the FDD and TDD co-site scenarios where FDD cell policies differ from TDD cell policies.

4.2 TDLBFD-00201805 Service Based Inter-frequency Handover This section describes the basic feature TDLBFD-00201805 Service Based Inter-frequency Handover. For details about the engineering guidelines for this feature, see 7.3 TDLBFD-00201805 Service Based Inter-frequency Handover. This feature is controlled by the following two options. The feature is activated only when both the following options are selected. l

Option 1: ServiceBasedInterFreqHoSwitch of the ENodeBAlgoSwitch.HoAlgoSwitch parameter

l

Option 2: SrvBasedInterFreqHoSw of the CellAlgoSwitch.HoAllowedSwitch parameter

Based on the QCIs of the services that are running on a UE, the eNodeB can divert the UE to one or certain appropriate co-coverage E-UTRAN frequencies by means of this feature to implement service steering. Table 4-17 lists the triggering and stopping conditions for triggering/stopping inter-frequency measurement and handover. This feature does not have a blind handover procedure.

4.2.1 Triggering and Stopping of Inter-Frequency Measurement To implement service-based inter-frequency handovers, operators need to configure servicebased inter-frequency handover policies. Since the services of each operator are classified by QCIs, each QCI can be associated with a service-based inter-frequency handover policy so that the frequency group specified by the policy preferentially carries the services with this QCI. The neighbor relationships corresponding to the different frequencies must be configured. The eNodeB triggers a service-based inter-frequency handover for a UE based on the highest-priority QCI of the services running on the UE. 1.

Set the service-based inter-frequency handover policy in the ServiceIfHoCfgGroup MO. Set the service-based inter-frequency handover policy (specified by the ServiceIfHoCfgGroup.InterFreqHoState parameter) for a downlink frequency (specified by the ServiceIfDlEarfcnGrp.DlEarfcn parameter) to PERMIT_HO.

2.

Assign the inter-frequency handover frequency policy for the QCI of operator(CnOperatorStandardQci.Qci or ExtendedQci.ExtendedQci).

3.

If the UE performs services with this QCI, which has the highest priority, and the frequency of the serving cell of the UE is not within the target frequency range expected to carry the services, the eNodeB delivers event A4 measurement configuration. Then, the UE measures the frequency or frequency group with the highest priority in the target frequency group (specified by the SERVICEIFDLEARFCNGRP.ServiceHoFreqPriority parameter).

If the ENodeBAlgoSwitch.ServiceHoMultiTargetFreqSw parameter is set to ON, services in a service group can be transferred to different E-UTRAN frequencies specified in the ServiceIfDlEarfcnGrp MO. When this parameter is set to OFF, services in a service group can be transferred only to the frequency with an index (specified by ServiceIfDlEarfcnGrp.DlEarfcnIndex) of 0.

4.2.2 Inter-Frequency Measurement If the measurement gap has been activated and includes other measurement gaps, the eNodeB does not reconfigure the measurement gap. Otherwise, the eNodeB activates the measurement gap. This prevents persistent gap-assisted inter-frequency measurements performed due to failures to receive measurement reports from affecting data transmission. The duration is specified by the ServiceIfHoCfgGroup.A4RptWaitingTimer parameter. Parameters in the measurement configuration for service-request-based inter-frequency measurement are the same as those for coverage-based inter-RAT measurement.

4.2.3 Inter-Frequency Handover Triggering Working principles of event A4 for triggering service-based inter-frequency handovers are the same as those of event A4 for triggering coverage-based inter-frequency handovers. For details, see 4.1.3.2 Event A4. All parameters (other than thresholds) for event A4 that triggers service-based inter-frequency handovers are the same as those for event A4 that triggers coverage-based inter-frequency handovers. Table 4-18 lists the thresholds related to event A4 that triggers service-based interfrequency handovers.

Service-based interfrequency RSRP triggering threshold

When the triggering type is RSRP:

This parameter is set for each QCI. The IntraRatHoComm.InterFreqHoA 4TrigQuan parameter determines the threshold to be used. l If IntraRatHoComm.InterFreqH oA4TrigQuan is set to BOTH, two A4 events are delivered, with one being RSRP-based and the other RSRQ-based. When the entering condition for either of event A4 is met, the UE reports event A4. l When IntraRatHoComm.InterFreqH oA4TrigQuan is set to RSRP or RSRQ, the eNodeB delivers a measurement configuration related to event A4 for which the triggering quantity is RSRP or RSRQ, respectively. The IntraRatHoComm.InterFreqHoA 4RprtQuan parameter determines the reporting quantity to be included in the measurement reports after event A4 is triggered. l When IntraRatHoComm.InterFreqH oA4RprtQuan is set to BOTH, two A5 events are reported, with one being RSRP-based and the other RSRQ-based. An interfrequency handover is triggered only when both measurement quantities meet the condition that the sum of the Mn, Ofn, Ocn, and Hys values is greater than or equal to the threshold value. l When IntraRatHoComm.InterFreqH oA4RprtQuan is set to SAME_AS_TRIG_QUAN(Sa me as Trig Quan), service-

based measurement report type for event A4 is the same as the measurement triggering quantity.

The event A4 triggering quantity for service-based inter-frequency handovers is determined by the IntraRatHoComm.InterFreqHoA4TrigQuan parameter. The hysteresis for servicebased inter-frequency event A4 is determined by the ServiceIfHoCfgGroup.A4TimeToTriger parameter. Other parameters related to the event A4 report for service-based inter-frequency measurement are the same as the parameters related to the event A4 report for coverage-based inter-frequency measurement. For details, see 4.1.3.2 Event A4. When UEs that trigger service-based inter-frequency measurement fail the outgoing handover and continue to camp in the source eNodeB, the eNodeB reads the CnOperatorQciPara.ServiceHoBearerPolicy parameter mapping each QCI. l

When this parameter is set to SERVICE_HO_QCI_NOT_ALLOWED(QCI Bear Not Allowed), the bearer for the corresponding QCI is deleted.

l

When this parameter is set to SERVICE_HO_QCI_ALLOWED(QCI Bear Allowed), the bearer for the corresponding QCI is not deleted. NOTE

To prevent the default bearers of UEs from being deleted, the CnOperatorQciPara.ServiceHoBearerPolicy parameter for QCI of 1 and QCI of 2 must be set to SERVICE_HO_QCI_NOT_ALLOWED(QCI Bear Not Allowed).

4.3 TDLBFD-00201804 Distance Based Inter-Frequency Handover This section describes the basic feature TDLBFD-00201804 Distance Based Inter-frequency Handover. For details about the engineering guidelines for this feature, see 7.4 TDLBFD-00201804 Distance Based Inter-Frequency Handover. The CellAlgoSwitch.DistBasedHoSwitch parameter specifies whether to enable distance-based inter-frequency handover. Distance-based inter-frequency handover can be triggered only when the DistBasedHO.DistBasedMeasObjType parameter is set to EUTRAN. Distance-based inter-frequency handover applies in multi-band hybrid networks where cells on a certain band cover relatively large areas and overshoot coverage occurs while neighbor relations are missing. As shown in Figure 4-11, band F1 is used to cover the urban area and band F2 is used to cover the suburban area. If there are only a few buildings along the border between the urban area and the suburban area, the RF signals from an F1 cell may be able to travel a long Issue 01 (2016-03-07)

distance (typically three times the distance between sites), causing overshoot coverage to an F2 cell. The triangle area in the UE moving direction indicates overshoot coverage. As there are restrictions on number of cells between two neighboring cells, Cell D cannot be configured as a neighboring cell of Cell A. However, because of overshoot coverage of Cell A, the UE cannot trigger coverage-based inter-frequency handover in Cell B and Cell C. When the UE reaches Cell D and moves out of the overshoot coverage area, service drops will occur because of the missing neighbor relationship. When distance-based inter-frequency handover is enabled, the UE can be handed over to Cell B or Cell C in time to avoid service drop. The deviation in the estimated distance between the UE and eNodeB is about 100 to 150 meters. NOTE

Obtaining the distance between the UE and the eNodeB is dependent on the uplink timing advance (TA). The eNodeB measures the TA of a UE and sends the TA value to the UE through a timing advance command. The TA accuracy is 16 Ts. Ts is the minimum time unit at the physical layer in LTE. The formula for calculating Ts is as follows: Ts = 1/(15000 x 2048)s = 32.55 ns. The formula for calculating the distance in a distance-based inter-frequency handover is as follows: 16 Ts/2 x Radio transmitting speed. That is, 16 x 32.55 ns /2 x 3 x 10^8 m/s = 78.12 m.

4.3.1 Triggering and Stopping of Inter-Frequency Measurement Distance-based inter-frequency handovers are triggered by the eNodeB based on the distance between the eNodeB and the UE. The eNodeB keeps monitoring the distance to all UEs. Upon detecting that the measured distance to a UE exceeds the threshold specified by the DistBasedHO.DistBasedHOThd parameter for 10 seconds (which is a fixed value), the eNodeB delivers the measurement configuration for event A4 to the UE. While the measurements for a distance-based inter-frequency handover are being taken, if the eNodeB detects that the reported TA value does not meet DistBasedHO.DistBasedHOThd for 10 seconds, the measurements are immediately stopped.

4.3.2 Inter-Frequency Measurement Before delivering the measurement configuration related to event A4, the eNodeB checks whether the measurement gap has been activated. If the measurement gap has been activated and includes other measurement gaps, the eNodeB does not reconfigure the measurement gap. Otherwise, the eNodeB activates the measurement gap. Parameters in the measurement configuration for distance-based inter-frequency measurement are the same as those for coverage-based inter-frequency measurement.

4.3.3 Inter-Frequency Handover Triggering Distance-based inter-frequency handovers can be triggered by event A4. Working principles of event A4 for triggering distance-based inter-frequency handovers are the same as those of event A4 for triggering coverage-based inter-frequency handovers.

It is recommended that the A2BasedFreqPriHoSwitch option of the CellAlgoSwitch.FreqPriorityHoSwitch parameter be deselected in multi-band samecoverage networking scenarios. When cells on a low band (for example, 900 MHz) and a high band (for example, 1800 MHz) have the same coverage, a frequency-priority-based inter-frequency handover can be performed to preferentially carry services in the high band while sparing the low band for continuous coverage.

for triggering frequency-priority-based inter-frequency handover when all the following conditions are met. After events A1 and A2 are reported, the eNodeB delivers inter-frequency measurement event A4 when all the following conditions are met: l

When the VoipMeasFreqPriSwitch option of the CellAlgoSwitch.MultiFreqPriControlSwitch parameter is selected, the HO_USE_VOIP_FREQ_ALLOWED option of the CellStandardQci.QciAlgoSwitch parameter is deselected for UEs. NOTE

During bear setup and release, this condition can be used to determine whether to stop or redeliver event A1/A2 for triggering frequency-priority-based inter-frequency handover.

The MlbBasedFreqPriHoSwitch option of the CellAlgoSwitch.FreqPriorityHoSwitch parameter is selected but the cell does not trigger MLB.

l

The LoadTriggerFreqPriHoSwitch option of the CellAlgoSwitch.FreqPriorityHoSwitch parameter is selected, and the eNodeB detects a cell that meets the following condition: Among its neighboring cells with the EutranInterFreqNCell.OverlapInd parameter set to YES(YES), the load of certain neighboring cells can be obtained through the X2 interface and the neighboring cells have not triggered UE-number-based MLB.

In the multi-band same-coverage networking scenario, during frequency-priority-based interfrequency measurement, the sequence that the measurement configurations of event A1 for triggering and event A2 for stopping inter-frequency measurements are sent is controlled by the ReduceInvalidA1A2EventRptSigSwitch option of the ENodeBAlgoSwitch.HoSignalingOptSwitch parameter. l

If the option is selected, the eNodeB sends measurement configuration for event A1 when the UE sets up an RRC connection, and sends measurement configuration for event A2 after it receives an event A1 from the UE.

A1A2 Measurement trigger quantity of Freq Priority

IntraRatHoComm.Fre qPriInterFreqHoA1Trig Quan

This is a common eNodeB-level parameter used for intra-RAT handovers. This parameter specifies the Ms type and triggering quantity for events A1 and A2.

Working principles of event A2 for triggering frequency-priority-based interfrequency measurement is the same as those of event A2 for triggering coverage-based interfrequency measurement. Parameters (other than those for thresholds and triggering quantity) in the measurement configuration for frequency-priority-based inter-frequency measurement are the same as those for coverage-based inter-frequency measurement.

This is a common eNodeB-level parameter used for intra-RAT handovers. This parameter specifies the Ms type and triggering quantity for events A1 and A2. The triggering quantity for event A2 for frequency-priority-based interfrequency measurement is the same as that for event A1 for frequencypriority-based inter-frequency measurement.

In the multi-band different-coverage networking scenario, if a UE has performed gap-assisted measurements for a period of time (internally set to 3s) but fails to receive the corresponding measurement report, the eNodeB stops the inter-frequency measurement.

4.5.2 Inter-Frequency Measurement If the measurement gap has been activated and includes other measurement gaps, the eNodeB does not reconfigure the measurement gap. Otherwise, the eNodeB activates the measurement gap. If a UE is performing gap-assisted measurements for a frequency-priority-based interfrequency handover and the VoipMeasFreqPriSwitch option of the CellAlgoSwitch.MultiFreqPriControlSwitch parameter is selected, the eNodeB stops frequency-priority-based inter-frequency measurement for UEs that set up bearers for voice services. Parameters (other than parameter for frequency selection) in the measurement configuration for frequency-priority-based inter-frequency measurement are the same as those for coveragebased inter-frequency measurement. The EutranInterNFreq.FreqPriBasedHoMeasFlag parameter specifies the measurement flag for a frequency for frequency-priority-based inter-frequency measurement. l

number allowed by 3GPP specifications, the eNodeB contains random frequencies in the measurement configuration. l

If EutranInterFreqNCell.BlindHoPriority is set to DISABLE(Disable), the selected inter-frequency neighboring cells must have a frequency priority ranging from 17 to 32. Only the frequencies of these cells are measured. The frequency priority is set by the EutranInterFreqNCell.BlindHoPriority parameter. If the number of target frequencies to be measured exceeds the maximum number allowed by 3GPP specifications, the eNodeB sorts the frequencies according to the value of the EutranInterFreqNCell.BlindHoPriority parameter and selects the frequencies of the neighboring cells with high priorities.

4.5.3 Inter-Frequency Handover Triggering Frequency-priority-based inter-frequency handovers can be triggered by event A4. Working principles of event A4 for triggering frequency-priority-based inter-frequency handovers are the same as those of event A4 for triggering coverage-based inter-frequency handovers. For details, see 4.1.3.2 Event A4. Parameters related to event A4 that triggers frequency-priority-based inter-frequency handovers are the same as those related to event A4 that triggers service-based interfrequency handovers. For details, see Table 4-28.

4.5.4 Blind Handover Triggering and Stopping Blind handover is triggered when the eNodeB receives an event A1 report from a UE and blind handover is enabled. Blind handover is enabled when the FreqPriorIFBlindHOSwitch option the CellAlgoSwitch.FreqPriorityHoSwitch parameter is selected.

Target Selection The target selection process of frequency-priority-based inter-frequency blind handover is the same as that of coverage-based inter-frequency blind handover. For details, see 4.1.4 Blind Redirection/Blind Handover. In frequency-priority-based blind handover, the target inter-frequency neighboring cell must have a blind-handover priority ranging from 17 to 32. The frequency priority is set by the EutranInterFreqNCell.BlindHoPriority parameter. If an inter-frequency neighboring cell is not configured with a blind-handover priority, the subsequent processing depends on the setting of the EutranInterNFreq.FreqPriBasedHoMeasFlag parameter. l

If EutranInterNFreq.FreqPriBasedHoMeasFlag is set to ENABLE(Enable), measurement is performed. The frequency of the neighboring cell is a target frequency. If the number of target frequencies to be measured exceeds the maximum number allowed by 3GPP specifications, the eNodeB contains random frequencies in the measurement configuration.

l

If EutranInterNFreq.FreqPriBasedHoMeasFlag is set to DISABLE(Disable), measurement is not performed.

4.6 High Speed UE Handover Frequency-based Redirection This section describes high speed UE handover frequency-based redirection. The HighSpeedUserRedirectSwitch option of the CellAlgoSwitch.HighSpeedSchOptSwitch parameter specifies whether to enable high speed UE handover frequency-based redirection. High speed UE handover frequency-based redirection applies to ultra-high-speed railway scenarios. Cell combination is not used in a public network, and therefore the high speed UE handover frequency is high. Based on how often handovers are performed, high speed UEs and low speed UEs on the public network can be distinguished so that high speed UEs Issue 01 (2016-03-07)


59



perform services on the ultra-high-speed railway dedicated network, low speed UEs perform services on the public network, and high speed UEs that are handed over from the dedicated network can be handed over back to the dedicated network in time.

4.6.1 Triggering and Stopping of Inter-Frequency Measurement High speed UE handover frequency-based redirection is triggered depending on the UE history information. For details about the engineering guidelines of this feature, see 7.6 Frequency-Priority-based Inter-Frequency Handover. If the number of cells in the UE history information is greater than or equal to the value of the CellHoParaCfg.SpeedEvaluatedNum parameter, the eNodeB accumulates the periods for the UE to stay in the lately visited cells, the number of which is specified by the CellHoParaCfg.SpeedEvaluatedNum parameter. If the accumulated value is less than the configured value of the CellHoParaCfg.SpeedEvaluatedPeriod parameter, high speed UE handover frequency-based redirection is triggered. If there are duplicated cells in the UE history information, you can infer that ping-pong handovers have occurred, and the periods of staying in these cells are not accumulated.

4.6.2 Inter-Frequency Measurement The eNodeB delivers only frequencies that meet both of the following conditions. Interfrequency measurement can be started even if no neighboring cells are configured under the frequency or the configured neighboring cells are handover-forbidden or blacklisted cells. l

Inter-frequencies supported by UE

l

Inter-frequencies with EutranInterNfreq.InterFreqHighSpeedFlag not set to LOW_SPEED

Before delivering the measurement configuration related to event A4, the eNodeB checks whether the measurement gap has been activated. If the measurement gap has been activated and includes other measurement gaps, the eNodeB does not reconfigure the measurement gap. Otherwise, the eNodeB activates the measurement gap. Parameters in the measurement configuration for high speed UE handover inter-frequencybased redirection measurement are the same as those for load-based inter-frequency measurement. For details, see MLB. To prevent a large number of public network UEs from being handed over to the dedicated network when the target frequencies for high speed UEs are set, you can use the following configurations: l

When ANR is disabled Neighboring cells of high speed frequencies are not configured to restrict public network UEs from being handed over to the high speed frequencies.

l

When ANR is enabled The ANR automatically adds neighboring cells and then initiates handovers. To prevent public network UEs from being handed over to the high speed frequencies, it is recommended that EutranInterFreqNCell.NoHoFlag of this frequency be set to FORBID_HO_ENUM, and EutranInterFreqNCell.BlindHoPriority of this frequency be set to 0.

To prevent public network UEs from being redirected to the high speed frequencies, it is recommended that EutranInterNFreq.ConnFreqPriority of this frequency be set to 0. Issue 01 (2016-03-07)


60



To prevent public network UEs from being reselected to the high speed frequencies, it is recommended that EutranInterNFreq.CellReselPriorityCfgInd of this frequency be set to NOT_CFG. To prevent ping-pong handovers, the high speed frequencies with this function enabled cannot serve as the target frequency for the following handovers: l

Frequency-priority-based handover

l

Service-based inter-frequency handover

l

For details about the SPID-specific handover back to the HPLMN policy, see Flexible User Steering Feature Parameter Description.

4.6.3 Inter-Frequency Handover Triggering High speed UE handover frequency-based redirection can be triggered by event A4. After receiving an event A4 measurement report from the UE, the eNodeB triggers redirection using the frequencies corresponding to the neighboring cell in event A4 measurement report as the target frequency. In this scenario, the eNodeB does not filter neighboring cells according to neighbor relationship or consider whether UEs support handovers.

4.7 Carrier-Attribute-based Inter-Frequency Handover This section describes carrier-attribute-based inter-frequency handover. Carrier-attributebased inter-frequency handover is enabled after TDLOFD-110223 Specified Service Carrier is enabled. For details about how to enable this feature, see WBB Feature Parameter Description.

4.7.1 Triggering and Stopping of Inter-Frequency Measurement The triggering procedure is as follows: 1.

When a UE accesses an eNodeB in scenarios of initial access, handover, or RRC connection reestablishment, the eNodeB checks whether the carrier of the serving cell is WBB carrier.

2.

If so, the eNodeB checks whether the UE is an MBB UE and non-emergency call UE.

3.

If so, the eNodeB triggers carrier-attribute-based inter-frequency handover.

l

If the UE supports inter-frequency measurement reporting, event A4 or A5 measurement configurations are delivered. After measurement is started, the ServiceIfHoCfgGroup.A4RptWaitingTimer. timer is started. If the UE still camps on the current cell when the timer expires, blind redirection is triggered.

l

If the UE does not support inter-frequency measurement reporting, blind redirection is triggered directly.

4.7.2 Inter-Frequency Measurement For carrier-attribute-based inter-frequency handover, an event A4 is used to trigger measurement. Specifically, when measurement configurations are delivered to CA UEs, the event A4 is changed to event A5, with the maximum value of threshold 1 of event A5 being fixed. During measurement frequency filtering, the inter-frequency with all-WBB-carriers of neighboring cells is filtered for non-emergency MBB UEs. Issue 01 (2016-03-07)

4.7.3 Inter-Frequency Handover Triggering Carrier-attribute-based inter-frequency handover is triggered by event A4 or A5 (event A4 is changed to event A5 for CA UEs). Working principles of event A4/A5 for triggering carrierattribute-based inter-frequency handovers are the same as those of event A4/A5 for triggering coverage-based inter-frequency handovers. For details, see 4.1.3.2 Event A4 and 4.1.3.3 Event A5. Table 4-29 describes the parameters related to event A4 that triggers carrier-attribute-based inter-frequency handovers.

4.8 TDLOFD-001050 Mobility between TDD-LTE and FDD-LTE This feature provides cell selection and reselection functions between TDD-LTE and FDDLTE. To implement better cell coverage, UEs can now be handed over between TDD-LTE and FDD-LTE cells.

TDLBFD-00201805


When the inter-frequency measurement frequency priority control is enabled for VoLTE UEs in the Coverage-based Inter-Frequency Handover feature, the VoLTE settings must be the same among frequencies if the service-based inter-frequency handover switch is turned on. Meanwhile, inter-frequency measurement frequency priority control does not take effect on VoLTE UEs.

Impacted Features

Network Impact

For coverage-based intra-frequency, coverage-based inter-frequency, service-based interfrequency, service drop rate may be affected. The following describes the methods of identifying and handling such situations. Certain UEs report to support inter-mode measurement but actually they do not support intermode measurement. When such UEs exist on the live network, the L.RRC.ReEst.ReconfFail.Att counter indicates a large number of RRC connection reestablishements. This affects the service drop rate on the live network. In this case, you are advised to enable LTE inter-mode measurement optimization. This function is controlled by the InterFddTddMeasComOptSw option of the GlobalProcSwitch.UeCompatSwitch parameter. NOTE

After this function is enabled, UEs supporting inter-mode measurement but not supporting inter-mode handover cannot be transferred to an inter-mode network through measurement-based redirection. Enabling this function does not affect UEs supporting both inter-mode measurement and inter-mode handover.

For details about the impact of each function on the network, see the corresponding section.

Network Performance Coverage-based intra-frequency handovers reduce interference from intra-frequency neighboring cells on an intra-frequency network, decreasing the service drop rate.

6.2 TDLBFD-00201802 Coverage Based Inter-frequency Handover System Capacity No impact.

Network Performance With coverage-based inter-frequency handovers, the coverage in areas with weak LTE coverage or coverage holes can be supplemented by inter-frequency neighboring cells, decreasing the call drop rate. The inter-frequency measurement priority control function allows VoIP UEs to be handed over to the optimal frequency. This reduces the number of handovers of VoIP UEs during continuous mobility. It is required that the frequency with the best signal quality can be measured by VoIP UEs. Otherwise, VoIP UEs experience service drops due to lack of measurements on neighboring cells on such a frequency. When this function is enabled, VoIP UEs are concentrated in the cells on the frequency with the best signal quality. If the bandwidth of such a frequency is small, the VoIP capacity may be limited.

7.1 TDLBFD-00201801 Coverage Based Intra-frequency Handover 7.1.1 When to Use Coverage-based Intra-Frequency Handover Mobility management is fundamental to service continuity. Coverage-based intra-frequency handovers are used by default. You are advised to keep this type of handover enabled.

7.1.2 Required Information Coverage-based intra-frequency handover is a basic feature and has no special requirements for the network and UE. To ensure the performance of coverage-based intra-frequency handover, verify that the EUTRAN provides effective and continuous coverage. If there are coverage holes in the EUTRAN, coverage-based intra-frequency handover may not achieve satisfactory performance. In addition, collect information about intra-frequency neighbor relationships to ensure the integrity of such relationships.

7.1.3 Requirements Operating Environment Coverage-based intra-frequency handovers have no requirements for operating environment.

Transmission Networking Coverage-based intra-frequency handovers have no requirements for transmission networking.

License Coverage-based intra-frequency handovers have no requirements for licenses.

Intrafreq handover hysteresi s

IntraFre qHoGro up.Intra FreqHoA 3Hyst


This parameter specifies the hysteresis for event A3 associated with intra-frequency handover. A larger hysteresis value causes a lower probability of triggering event A3, affecting user experience. A smaller hysteresis value causes a higher probability of triggering event A3 but also a higher probability of incorrect handover decisions and ping-pong handovers.

If you want to set different intra-frequency handover parameters for services with a specific QCI, you must create a parameter group, and reference the parameter group ID to the corresponding QCI.

The average number of handovers has a negative correlation with the time-to-trigger. At the same time, an excessively large value of the time-to-trigger results in a high risk of service drops. It is recommended that you adjust the parameter value with IntraFreqHoGroup.IntraFreqHoA3Offset based on the application scenario. Increase the parameter value if premature intra-frequency handovers occur. Decrease the parameter value if delayed intrafrequency handovers occur.

An excessively large parameter value, however, causes a long delay in retries and a low handover success rate. It is recommended that the default value be used.

7.1.9 Troubleshooting Fault Description An eNodeB may not initiate a handover procedure upon receipt of an event A3 measurement report.

Fault Handling When this problem occurs, perform the following steps to determine whether it has occurred because the target cell has not been configured as a neighboring cell: Step 1 Check the messages over the Uu interface and locate the PCI of the neighboring cell in the measurement report. Step 2 Run the LST EUTRANEXTERNALCELL command to list all external E-UTRAN cells of the eNodeB, run the LST CELL command to list all local cells of the eNodeB, and check these lists for the cell whose PCI equals the PCI found in the previous step. l

If this cell can be found, go to Step 4.

l

If this cell cannot be found, the target cell has not been configured as an external cell. To solve this problem, go to Step 3.

Step 3 Find out the CGI of the cell whose PCI equals the PCI found in Step 1 in the command output in Step 2. Then, run the ADD EUTRANINTRAFREQNCELL command to add the CGI to the EutranIntraFreqNCell MO. Step 4 Find out the CGI of the cell whose PCI equals the PCI found in Step 1 in the command output in Step 2. Then, run the ADD EUTRANEXTERNALCELL and ADD EUTRANINTRAFREQNCELL commands to add the CGI to the EutranExternalCell and EutranIntraFreqNCell MOs, respectively. ----End

7.2 TDLBFD-00201802 Coverage Based Inter-frequency Handover 7.2.1 When to Use Coverage-based Inter-Frequency Handover Mobility management is fundamental to service continuity. Coverage-based inter-frequency handovers are used by default. You are advised to keep this type of handover enabled. If the live network does not require inter-frequency networking, you can disable coveragebased inter-frequency handover.

7.2.2 Required Information If blind redirection/blind handover is required in inter-frequency handover, collect information about neighboring cells of each cell and their corresponding priorities. The information to be collected before deploying coverage-based inter-frequency handover includes the information to be collected before deploying coverage-based intra-frequency handover. Collect UE information to determine whether the eNodeB needs to handle UEs that report an abnormal frequency-supporting capability. In addition, collect the information about the coverage at the inter-frequency handover area. This information serves as a basis for setting the thresholds used to trigger events A1, A2, and A4. The event A2 threshold for coverage-based inter-frequency handover and the event A2 threshold for coverage-based inter-RAT handover can be separately set. If users expect coverage-based inter-frequency handover to be triggered earlier than coverage-based interRAT handover, the event A2 threshold for coverage-based inter-frequency handover must be set to a value greater than the event A2 threshold for coverage-based inter-RAT handover.

Event A3 is recommended for coverage-based interfrequency handovers in such scenarios as it provides better handover performance. l When the interference of two cells is irrelevant, the absolute threshold of signal quality is used as the handover criterion. Event A4 is recommended for coverage-based inter-frequency handovers in such scenario. l There is no recommended scenario for event A5.

Connect frequency priority

Based on the frequency priority specified by this parameter, the eNodeB selects a target frequency for blind redirection or contains a frequency in a measurement configuration. A larger value indicates a higher priority. If this priority is set to 0 for a frequency, this frequency is not selected as the target frequency for a blind redirection. Multiple frequencies can be configured with the same priority. If multiple frequencies have the highest priority, the eNodeB randomly selects one from them. You are advised to set this parameter for frequencies with continuous coverage.

This parameter value plus the value of InterFreqHoGroup.InterFreqHoA2ThdR srp or InterFreqHoGroup.A3InterFreqHoA2Th dRsrp is the offset of the RSRP threshold for LTE FDD inter-frequency measurement event A2. Set this parameter based on the actual conditions. NOTE In the FDD and TDD co-site scenarios where FDD cell policies differ from TDD cell policies, you can configure the cell-level parameter CellOpHoCfg.TddIfHoA2ThdRsrpOffset. That is, when eNodeB- and cell-level parameters coexist, the cell-level parameter is used as the actual value.

7.2.5 Activation Observation This section uses A4-triggered inter-frequency handover as an example. The observation procedure is as follows: Step 1 Trace messages over the Uu interface on the U2000 client after UEs access the network. Check the RRC_CONN_RECFG message. If the message contains measurement configuration of events A1 and A2 for a coverage-based inter-frequency handover, you can infer that coverage-based inter-frequency handover has been activated. Step 2 Trace messages over the Uu interface while the UE is moving towards the cell edge. After the eNodeB receives an A2-related measurement report from the UE, check the RRC_CONN_RECFG message that contains the inter-frequency measurement configuration and A4-related measurement report information. Step 3 Trace messages over the Uu interface after the UE moves to the cell edge. Check the RRC_CONN_RECFG message, which is a handover command, after the eNodeB receives an A4-related measurement report from the UE. If the message contains target cell access information, you can infer that coverage-based inter-frequency handover has been triggered. ----End

Interfreq A1A2 hysteresis

InterFreq HoGroup. InterFreq HoA1A2H yst


This parameter specifies the hysteresis for events A1 and A2 for inter-frequency measurement. A larger value causes a lower probability of triggering event A1 or A2 for inter-frequency measurement. A smaller value causes a higher probability. It is recommended that the default value be used.

Interfreq A1A2 time to trigger

InterFreq HoGroup. InterFreq HoA1A2Ti meToTrig


This parameter specifies the time-to-trigger for events A1 and A2 for inter-frequency measurement. This time-to-trigger effectively reduces the number of inter-frequency measurements to be started, preventing unnecessary inter-frequency measurement. The average number of inter-frequency measurements to be started has a negative correlation with the time-to-trigger. At the same time, an excessively large value of the time-to-trigger results in a high risk of service drops. It is recommended that the default value be used.


InterFreq HoGroup. InterFreq HoA1Thd Rsrp


This parameter specifies the RSRP threshold for event A1 associated with inter-frequency measurement. A larger value causes a lower probability of triggering event A1. A smaller value causes a higher probability. The value of this parameter must be (usually 4 dB) greater than or equal to the sum of the value of InterFreqHoGroup.InterFreqHoA2ThdRsr p and RSRP threshold offset for event A2 for inter-frequency measurement (set in the CnOperatorHoCfg MO).


InterFreq HoGroup. InterFreq HoA1Thd Rsrq


This parameter specifies the RSRQ threshold for event A1 for inter-frequency measurement. A larger value causes a lower probability of triggering event A1. A smaller value causes a higher probability. The value of this parameter must be (usually 2 dB) greater than or equal to the value of InterFreqHoGroup.InterFreqHoA2ThdRsr q.

CoverageB ased Interfreq RSRP threshold



This parameter specifies the RSRP threshold for event A4 in a coverage-based, ULquality-based, or distance-based handover, or in a SPID-based handover to the HPLMN. A larger value causes a lower probability of triggering event A4. A smaller value causes a higher probability. The value of this parameter must be greater than the sum of the peer-end RSRP threshold for event A2 for inter-frequency measurement (set in the InterFreqHoGroup MO at the peer eNodeB) and the RSRP threshold offset for event A2 for inter-frequency measurement for the higher-priority RAT(set in the CnOperatorHoCfg MO at the peer eNodeB).

CoverageB ased Interfrq RSRQ threshold



This parameter specifies the RSRQ threshold for event A4 in a coverage-based, ULquality-based, or distance-based handover, or in a SPID-based handover to the HPLMN. A larger value causes a lower probability of triggering event A4. A smaller value causes a higher probability. The value of this parameter must be greater than or equal to the peer-end RSRQ threshold for event A2 for inter-frequency measurement set at the peer eNodeB (set in the InterFreqHoGroup MO at the peer eNodeB).


InterFreq HoGroup. InterFreq HoA4Tim eToTrig


This parameter specifies the time-to-trigger for event A4. A larger value causes a lower probability of handover to inter-frequency neighboring E-UTRAN cells and a smaller average number of handovers, but a higher risk of service drops. A smaller value causes the opposite effect. If both coverage-based inter-frequency handovers and coverage-based inter-RAT handovers are enabled, you are advised to set the time-to-trigger for the inter-frequency handover event to be smaller than that for the inter-RAT handover event so that intra-RAT is preferentially performed. This helps increase the possibility of inter-frequency handovers.

Interfreq A3 offset

InterFreq HoGroup. InterFreq HoA3Offs et


This parameter specifies the offset for event A3 associated with inter-frequency handover. It determines the border between the serving cell and the neighboring cell. If the parameter is set to a large value, an inter-frequency handover is performed only when the signal quality of the neighboring cell is significantly better than that of the serving cell and other triggering conditions are met. It is recommended that you adjust the parameter value based on the application scenario. Increase the parameter value if premature inter-frequency handovers occur. Decrease the parameter value if delayed interfrequency handovers occur.

A3 based Interfreq A2 RSRP threshold

InterFreq HoGroup. A3InterFr eqHoA2T hdRsrp


This parameter specifies the RSRP threshold for event A2 associated with event-A3triggered inter-frequency handover.

VoIP Priority

EutranIn terNFreq. VoipPriori ty


This parameter is required when the interfrequency measurement frequency priority control is enabled for VoIP UEs. The priority is set in descending order based on cell coverage status. The frequency with better coverage is set with higher priority. For frequencies with the same coverage status, their priorities can be set to the same value. If the neighboring cells fill coverage holes of each other, the priorities for the frequency of such neighboring cells can be set to the same value. Assume that a site needs to be added to resolve weak coverage in the network. The frequency of Cell 1 in this site is F1, Cell 2 is a neighboring cell of Cell 1, and among the neighboring frequencies of Cell 2, the VoIP priority for F2 is the highest. In this situation, the VoIP priority for F1 must be reconfigured to be the same as the VoIP priority for F2.

An excessively large parameter value, however, causes a waste of air interface resources. It is recommended that the default value be used.

Measurem ent A4 report quantity

IntraRatHo Comm.Inter FreqHoA4Rp rtQuan


This parameter specifies the reporting quantity to be included in the measurement reports after event A4 is triggered.

That is, the measurement results can be RSRP-based, RSRQ-based, or both in A4-related measurement reports. It is recommended that the default value be used if the traffic load of LTE cells is not stable.

Interfreq measurem ent report interval

IntraRatHo Comm.Inter FreqHoRprtI nterval


This parameter specifies the interval between every two reports that are triggered by event A4. A smaller value causes more measurement reports and greater consumption of air interface resources, but a higher probability of triggering handovers. An excessively large parameter value, however, causes a long delay in retries and a low handover success rate. It is recommended that the default value be used.

If the value of this IE is not radioNetwork: radio-connection-with-ue-lost, the handover parameters are set correctly. Contact Huawei technical support engineers.

Step 2 Check the messages over the Uu interface for A4 measurement reports in RRC_MEAS_RPRT messages prior to RRC_CONN_REL messages. l

If such reports cannot be found, this problem is due to inappropriate settings of handover parameters. Go to Step 3.

7.3.5 Activation Observation The observation procedure is as follows: Step 1 Trace messages over the S1 interface after a UE accesses the network at the center of a cell in the 2600 MHz band and sets up a handover-enabled dedicated bearer with a QCI of 2. Check the S1AP_ERAB_SETUP_REQ message. If the message contains dedicated-bearer configuration, you can infer that service-based inter-frequency handover has been activated. Step 2 Trace messages over the Uu interface on the U2000 client. Check the RRC_CONN_RECFG message that contains the A4-related inter-frequency measurement configuration for servicebased handover.

This parameter specifies the RSRP threshold for event A4 for load-based, frequencypriority-based, and service-based interfrequency handovers. A larger value causes a lower probability of triggering event A4. A smaller value causes a higher probability. The value of this parameter must be greater than the sum of the peer-end RSRP threshold for event A2 for inter-frequency measurement (set in the InterFreqHoGroup MO at the peer eNodeB) and the RSRP threshold offset for event A2 for inter-frequency measurement (set in the CnOperatorHoCfg MO at the peer eNodeB).

A4 Measurem ent Trigger Quantity

IntraRatHo Comm.Inter FreqHoA4Tri gQuan


This parameter specifies the event A4 triggering quantity for inter-frequency handovers other than coverage-based inter-frequency handovers. The quantity can be either RSRP or RSRQ, or both. The measured RSRP values are stable, slightly varying with the load, and therefore there is little signal fluctuation. The measured RSRQ values vary with the load and are likely to reflect the signal quality of the cell in real time. It is recommended that the default value be used if the traffic load of LTE cells is not stable.

7.3.9 Troubleshooting Fault Description A UE with a service of QCIx may not be handed over to a cell working at frequency F1 after the handover policy has been set to enable services with QCIx to be handed over to a cell working at frequency F1.

Fault Handling Perform the following steps to determine whether the handover parameters are set correctly: Step 1 Check the messages over the S1 interface and locate the e-RABlevelQoSParameters IE in the S1AP_INITIAL_CONTEXT_SETUP_REQ message and the S1AP_ERAB_SETUP_REQ message (which may not exist). l

If QCIx is not contained in the e-RABlevelQoSParameters IE, ignore this fault and perform the test again after verifying that the UE has set up a service with QCIx.

l

If QCIx is contained in the e-RABlevelQoSParameters IE, check whether the UE has set up a service which is not allowed to be handed over to a cell working at F1 because of its QCI. –

If yes, perform the test again after the UE has stopped this service.

–

If no, go to step 2.

Step 2 Check the messages over the Uu interface for A4 measurement reports in RRC_MEAS_RPRT messages. l

7.4 TDLBFD-00201804 Distance Based Inter-Frequency Handover 7.4.1 When to Use Distance-based Inter-Frequency Handover If high bands and low bands are used to cover separate areas that border each other, RF signals from a high-band cell may be able to travel a long distance (for example, three times the inter-site spacing) and cause severe overshoot coverage to low-band cells. If the low-band cells are not configured as neighboring cells of the high-band cell, inter-frequency measurements cannot be triggered in time and call drops will occur. To reduce the probability of such call drops, you can enable distance-based inter-frequency handover.

7.4.2 Required Information Before deploying distance-based inter-frequency handover, collect information about the distance that the RF signals of the cell exerting overshoot coverage based on the inter-eNodeB distance on the live network. This distance is the criterion for the distance-based interfrequency handover threshold.

7.5 UL-Quality-based Inter-Frequency Handover 7.5.1 When to Use UL-quality-based Inter-Frequency Handover Coverage-based inter-frequency handovers are triggered based on DL signal quality. However, there may be a huge imbalance between the DL and UL signal quality: The UL signal quality may be relatively poor while the DL signal quality is fairly satisfactory. If this occurs, inter-frequency handovers cannot be promptly triggered. To handle this problem, you can enable UL-quality-based inter-frequency handover.

7.5.2 Required Information Before deploying UL-quality-based inter-frequency handover, collect the causes of the imbalance between the UL and DL signal quality as well as the possible magnitudes of the imbalance. In addition, you need to collect the requirements of the local network plan for the UL data rate at the cell edge.

Step 2 Observe the user-level measurement result on the U2000 (choose Monitor > Signaling Trace > Signaling Trace Management, and observe the value of BLER Monitoring in User Performance Monitoring.) l

When the user uplink IBLER increases gradually, observe the messages traced over the Uu interface. If the RRC_CONN_RECFG message from the eNodeB contains measurement control information for the inter-frequency handover and the RRC_CONN_RECFG message received by the eNodeB contains information of the target cell for an inter-frequency handover, you can infer that UL-quality-based interfrequency handover has been activated.

l

When the user uplink IBLER increases suddenly but has not reached 99%, observe the messages traced over the Uu interface. If the RRC_CONN_REL message from the eNodeB contains target frequency information, you can infer that UL-quality-based inter-frequency handover has been activated.

7.6 Frequency-Priority-based Inter-Frequency Handover 7.6.1 When to Use Frequency-Priority-based Inter-Frequency Handover You are advised to enable frequency-priority-based inter-frequency handover in the following scenarios: l

Frequency-priority-based inter-frequency handover applies to the following scenario: Some eNodeB sites use a high frequency band (for example, 2600 MHz) and a low band (for example, 900 MHz) as co-coverage bands. The high band is preferentially used to provide services, and the low band is used to ensure continuous coverage. In this scenario, frequency-priority-based inter-frequency handover can be used to hand over UEs from the low to high band. Note that frequency-priority-based inter-frequency handovers are performed to transfer UEs only from the low band to the high band. If a UE needs to be handed over from the high band to the low band, a coverage-based interfrequency handover can be performed.

l

In a different-coverage networking scenario with bands of different bandwidth, you can enable frequency-priority-based inter-frequency handover to enable the band with higher bandwidth to provide services when the network load is light.

7.6.2 Required Information If blind handover is required for inter-frequency handovers, the target cells for blind handover or blind redirection must be specified for each cell, and the corresponding blind handover priorities must be configured. Collect information about the coverage of different bands. This information serves as a basis for setting the thresholds used to trigger events A1, A2, and A4. If blind handover is used in frequency-priority-based inter-frequency handover scenarios, collect information about the neighboring cells to configure them with blind handover priorities in the range of 17 to 32.

Blind handov er Priority

EutranInte rFreqNCell .BlindHoPr iority


If this parameter value is set to 0, blind handovers and frequency-priority-based handovers cannot be performed. The values 1 to 16 indicate blind-handover priorities. Multiple neighboring cells can be configured with the same blind-handover priority. If multiple neighboring cells have the highest blindhandover priority, the eNodeB randomly selects one from them. The values 17 to 32 indicate the priorities for frequency-priority-based handovers. Set this parameter (with a value ranging from 1 to 16) only for those interfrequency neighboring cells that have overlapped coverage with the serving cell. Set this parameter to a larger value for a neighboring cell that has wider overlapped coverage or a lower frequency. Set this parameter to 0 for all inter-frequency neighboring cells if no inter-frequency neighboring cells have overlapped coverage with the serving cell.

7.7 High Speed UE Handover Frequency-based Redirection

Issue 01 (2016-03-07)


145



7.7.1 When to Use High Speed UE Handover Frequency-based Redirection High speed UE handover frequency-based redirection applies to high UE mobility or ultrahigh-speed railway scenarios to prevent frequent handovers of UEs accessing the public network during high mobility.

7.7.2 Required Information Before deploying high speed UE handover frequency-based redirection, collect information about whether public and private inter-frequency networks can meet continuous coverage requirements. If continuous coverage requirements cannot be met, user experience with services requiring handovers will be affected. Event A4 measurement is performed for high speed UE handover frequency-based redirection. The measurement threshold needs to be configured based on the collected coverage information about the high and low frequency bands. This feature transfers historical cell information about UE handovers based on the X2 interface. Therefore, X2-based inter-cell handover must be configured for the feature.

If no neighboring cells are configured for blind handovers when blind redirection is triggered, the eNodeB selects a target frequency for blind redirection based on the frequency priority specified by this parameter. If this priority is set to 0 for a frequency, this frequency is not selected as the target frequency for a blind redirection. The value 0 is therefore recommended.

The RRC_CONN_RECFG message in the Uu interface tracing result indicates that high-mobility frequencies are delivered in the A4 measurement control information for high-speed UE handover frequency-based redirection. This means that the high speed UE handover frequency-based redirection feature has been activated. Step 2 Check the Uu interface tracing messages. After the A4 measurement report is sent to the eNodeB, the eNodeB delivers a redirection command to instruct the high-speed UE to be redirected to a dedicated network cell. In the RRC_RELEASE message delivered from the public network cell for redirection, the target frequency information is available, indicating that high speed UE handover frequency-based redirection has been activated. ----End

Meaning: Indicates the time-to-trigger for intra-frequency handover event A3. When the UE detects that the signal quality in the serving cell and that in at least one neighboring cell meet the entering condition, it does not immediately send a measurement report to the eNodeB. Instead, the UE sends a report only when the signal quality meets the entering condition throughout the time-to-trigger. This parameter helps decrease the number of occasionally triggered event reports, the average number of handovers, and the number of incorrect handovers, preventing unnecessary handovers.

Meaning: Indicates the quantity to be included in the measurement report for the intra-frequency handover event. The quantity can be RSRP, RSRQ, or both. The measured RSRP values are stable, varying little with the load, and therefore there is little signal fluctuation. The measured RSRQ values vary with the load and are likely to reflect the signal quality of the cell in real time. Even when this parameter is set to BOTH, the eNodeB triggers a handover based on the setting of the IntraFreqHoA3TrigQuan parameter. The value of this parameter is also used as the quantity to be included in the measurement report between A3related inter-frequency measurement reports. For details, see 3GPP TS 36.331.

Indicates whether to enable handover signaling optimization. ReduceInvalidA1A2RptSigSwitch: Indicates whether to optimize the sequence in delivering A1/A2 measurement configurations during coverage- or frequency-priority-based handovers. If this option is selected: (1) In coverage-based handovers, the eNodeB delivers A2 measurement configurations to UEs first, and then delivers A1 measurement configurations to UEs after receiving event A2 reports, reducing signaling overheads in reporting unnecessary event A1. (2) In frequency-priority-based handovers, the eNodeB delivers A1 measurement configurations to UEs first, and then delivers A2 measurement configurations to UEs after receiving event A1 reports, reducing signaling overheads in reporting unnecessary event A2. MultiQciHoExecOptSwitch: Indicates whether the handover decision is triggered based on the admission result of all QCIs in SPID-based handovers to HPLMN and frequency-priority-based handovers. If this option is selected, the handover decision is triggered only when all QCI services are successfully admitted. If this option is deselected, the handover decision is triggered when any of the QCI services is successfully admitted. ReduceInvalidFreqPriHoSwitch: Indicates whether to avoid repeated switchovers between the frequencypriority-based intra-eNodeB handover algorithm and the load-based intra-eNodeB handover algorithm. If this option is selected, the eNodeB evaluates whether to perform a frequency-priority-based intra-eNodeB handover based on the settings of InterFreqMlbSwitch of the MlbAlgoSwitch parameter and the load status on the target cell. If the target cell is heavily loaded, the eNodeB does not trigger the handover. If this option is deselected, the eNodeB evaluates whether to perform a frequency-priority-based intra-eNodeB handover without checking the settings of InterFreqMlbSwitch of the MlbAlgoSwitch parameter on the target cell. AddA2MeasIfQciAdjSwitch: Indicates whether an eNodeB delivers inter-frequency or inter-RAT A2related measurement configuration to the UE when the QCI of services running on the UE changes in a

coverage-based handover. If this option is selected, the eNodeB performs the following operations each time the QCI is changed: (1) Updates the delivered handover-related parameters; (2) Determines whether inter-frequency or inter-RAT measurement configurations need to be delivered; (3) Delivers the configurations if they are required and have not been delivered before, or updates the configurations if they have been delivered and the current event A2 thresholds for inter-frequency or inter-RAT measurements are less than or equal to the event A2 threshold for blind handling. If this option is deselected, the eNodeB only determines whether delivered handover-related parameters need to be updated each time the QCI is changed. InterFreqHoA2OptSwitch: Indicates whether to deliver A2-related measurement configurations to UEs that do not support inter-frequency measurements. A2-related measurement configurations are not delivered to such UEs when this option is selected. This option is deselected by default. McUtranNcellNumOptSwtich: Indicates the maximum number of neighboring cells contained in the measurement configuration delivered to a UE for measurements when ANR with UTRAN is enabled. If this option is deselected, the maximum number is specified according to 3GPP TS36.331 earlier than V10.12.0 and is equal to the minCellperMeasObjectRAT parameter value. If this option is selected, the maximum number is specified according to 3GPP TS 36.331 V10.12.0 and later versions and is equal to the minCellperMeasObjectRAT parameter value minus 1. For details about the minCellperMeasObjectRAT parameter, see 3GPP TS 36.331. ReduceMeasCtrlMesNumSwitch: Indicates whether to reduce the number of Uu interface measurement configuration messages that are delivered for E-RAB setup, removal, and modification. If this option is selected, the eNodeB combines the E-RAB setup, removal, and modification and measurement configuration in a single RRC Connection Reconfiguration message. If this option is deselected, the eNodeB delivers the E-RAB setup, removal, and modification and measurement configuration separately in two RRC Connection Reconfiguration messages.

ServiceReqInterFreqBlindHoSw: Indicates whether to trigger a service-based blind inter-frequency handover. If this option is selected, when an FDD+TDD CA UE using a TDD CC as the PCC triggers a service-based inter-frequency handover and the target cell is an FDD SCell of the UE, the UE is handed over to this cell through PCC blind handover. The eNodeB triggers a blind handover with an indication of the target FDD SCC based on the SCC configuration of the target cell. If this option is deselected, the eNodeB triggers a measurement-based handover to the FDD SCell and configures SCCs again for the UE in the previous situation. This option applies only to LTE TDD cells. HOSuccRateBoostOptSwitch:Indicates the selection of the PDCCH CCE aggregation level for RAR retransmission in the case of non-contention-based handovers and the number of RBs allocated for Msg3 transmitted based on non-contention-based random access preamble. If this option is selected, the PDCCH CCE aggregation level is changed to level 8 for both LTE FDD and TDD cells when the RAR message for non-contention-based handovers is retransmitted, and the eNodeB allocates three RBs for Msg3 transmitted based on a non-contention-based random access preamble. If this option is deselected, the PDCCH CCE aggregation level for RAR transmission in the case of non-contention-based handovers is fixed to the value of the ComSigCongregLv parameter in the CellPdcchAlgo MO in both LTE FDD and TDD cells, and the eNodeB allocates eight RBs for Msg3 transmitted based on a non-contention-based random access preamble. For cells working on small bandwidths such as 1.4 MHz and 3 MHz, it is recommended that the HOSuccRateBoostOptSwitch option be deselected.

Indicates the time-to-trigger of event A1/A2 for triggering inter-frequency measurement. When detecting that the signal quality in the serving cell meets the triggering condition, the UE does not send a measurement report to the eNodeB immediately. Instead, the UE sends a report only when the signal quality continuously meets the entering condition during the time-to-trigger.

The value of this parameter plus the value of the A3InterFreqHoA2ThdRsrp parameter equals the RSRP threshold of event A2 of event A3-based LTE FDD inter-frequency handover. The value of this parameter plus the value of the InterFreqHoA2ThdRsrp parameter equals the RSRP threshold of event A2 of event A4/A5-based LTE FDD inter-frequency handover. If the TddIfHoA2ThdRsrpOffset and FddIfHoA2ThdRsrpOffset parameters are set to the same value excluding the value -100, inter-frequency event A2 is delivered directly without considering LTE TDD and LTE FDD measurement priorities in coverage-based inter-frequency measurement scenarios, and the RSRP threshold of inter-frequency event A2 equals the value of the A3InterFreqHoA2ThdRsrp parameter or the InterFreqHoA2ThdRsrp parameter plus the value of the FddIfHoA2ThdRsrpOffset parameter or the TddIfHoA2ThdRsrpOffset parameter. If both the TddIfHoA2ThdRsrpOffset and FddIfHoA2ThdRsrpOffset parameters are set to -100, inter-frequency event A2 is delivered directly without considering LTE TDD and LTE FDD measurement priorities in coverage-based inter-frequency measurement scenarios, and the RSRP threshold is the value of the A3InterFreqHoA2ThdRsrp parameter or the InterFreqHoA2ThdRsrp parameter.

Indicates the offset of the RSRP threshold of LTE TDD inter-frequency measurement event A2 relative to the RSRP threshold of event A2 of event A3-based inter-frequency handover (specified by the A3InterFreqHoA2ThdRsrp parameter) and the RSRP threshold of event A2 of event A4/A5-based interfrequency handover (specified by the InterFreqHoA2ThdRsrp parameter). The value of this parameter plus the value of the A3InterFreqHoA2ThdRsrp parameter equals the RSRP threshold of event A2 of event A3-based LTE TDD inter-frequency handover. The value of this parameter plus the value of the InterFreqHoA2ThdRsrp parameter equals the RSRP threshold of event A2 of event A4/A5-based LTE TDD inter-frequency handover. If the TddIfHoA2ThdRsrpOffset and FddIfHoA2ThdRsrpOffset parameters are set to the same value excluding the value -100, inter-frequency event A2 is delivered directly without considering LTE TDD and LTE FDD measurement priorities in coverage-based inter-frequency measurement scenarios, and the RSRP threshold of inter-frequency event A2 equals the value of the A3InterFreqHoA2ThdRsrp parameter or the InterFreqHoA2ThdRsrp parameter plus the value of the TddIfHoA2ThdRsrpOffset parameter or the FddIfHoA2ThdRsrpOffset parameter. If both the TddIfHoA2ThdRsrpOffset and FddIfHoA2ThdRsrpOffset parameters are set to -100, inter-frequency event A2 is delivered directly without considering LTE TDD and LTE FDD measurement priorities in coverage-based inter-frequency measurement scenarios, and the RSRP threshold is the value of the A3InterFreqHoA2ThdRsrp parameter or the InterFreqHoA2ThdRsrp parameter. If the TddIfHoA2ThdRsrpOffset parameter is set to -100 and the FddIfHoA2ThdRsrpOffset parameter is not set to -100, coverage-based LTE TDD measurement is not triggered, and the eNodeB delivers only the RSRP threshold of LTE FDD interfrequency event A2, which is used to enable coveragebased LTE FDD inter-frequency measurement. The RSRP threshold of LTE FDD inter-frequency event A2 equals the value of the A3InterFreqHoA2ThdRsrp parameter or the InterFreqHoA2ThdRsrp parameter

Meaning:




Indicates the time-to-trigger for event A4 for the interfrequency handover. When detecting that the signal quality in at least one neighboring cell meets the entering condition, the UE does not send a measurement report to the eNodeB immediately. Instead, the UE sends a report only when the signal quality continuously meets the entering condition during the time-to-trigger. This parameter helps decrease the number of occasionally triggered event reports, the average number of handovers, and the number of wrong handovers.

Meaning: Indicates the trigger quantity for event A1/A2 of inter-RAT measurement. The quantity can be RSRP, RSRQ, or both RSRP and RSRQ. The measured RSRP values are stable, varying little with the load, and therefore there is little signal fluctuation. The measured RSRQ values vary with the load and are likely to reflect the signal quality of the cell in real time. For details, see 3GPP TS 36.331.

Indicates the time-to-trigger of A1/A2 for triggering inter-RAT measurement. When detecting that the signal quality in the serving cell meets the entering condition, the UE does not send a measurement report to the eNodeB immediately. Instead, the UE sends a report only when the signal quality continuously meets the entering condition during the time-to-trigger. This parameter helps decrease the number of occasionally triggered event reports, the average number of handovers, and the number of wrong handovers. In summary, it helps prevent unnecessary handovers.

BlindHo Priority


LBFD-0 0201802 / TDLBF D-00201 802


Meaning: Indicates the priority of the neighboring cell during handovers. The parameter values are divided into three segments, indicating the blind-handover priority, frequency-based-handover priority, and 0. Within the same segment, a larger parameter value indicates a higher priority. Blind handover is a process in which the eNodeB instructs a UE to hand over to a specified neighboring cell without measurements. If this parameter value is set to 0, blind handovers and frequency-based handovers cannot be performed. The parameter values 1 to 16 indicate the blind-handover priorities. The parameter values 17 to 32 indicate the frequency-based-handover priorities for frequencybased blind handovers and measurement-based handovers.

Indicates whether to enable the scheduling optimization algorithm in highway or high-speed railway scenarios. InterfHighSpeedSW: Indicates whether to enable coordinated scheduling and interference resistance in high-speed railway scenarios. If this option is selected, coordinated scheduling and interference resistance in high-speed railway scenarios is enabled and the eNodeB works with the eCoordinator to perform coordinated scheduling between public and dedicated networks. If this option is deselected, coordinated scheduling and interference resistance in high-speed railway scenarios is disabled. This option applies only to TDD cells. HighSpeedUserRedirectSwitch: Indicates whether to redirect high-speed UEs to high-speed frequencies. If this option is selected in a common cell near the highspeed railway, the eNodeB redirects the UEs that are handed over frequently to a high-speed railway dedicated network. In other scenarios, it is recommended that this option be deselected. This option applies only to TDD cells. DlAfcSwitch: Indicates whether to enable downlink AFC in a high-speed cell served by multiple RRUs. The AFC function is valid to the downlink data, which decreases the performance loss caused by high-speed mobility. If this option is selected, downlink AFC is enabled. If this option is deselected, downlink AFC is disabled. ProcSwitchBasedOnUserSpeed: Indicates whether to enable UE-speed-based differentiated processing in high-speed railway cells. If this option is selected, cells support identification of UE speed attributes and differentiated processing on UE-speed-based functions and parameters. This parameter applies only to LTE FDD. SpeedBasedMimoAdpSwitch: Indicates whether to enable UE-speed-based adaptive MIMO configurations in high-speed railways cells. If this option is selected, cells support identification of UE speed attributes and differentiated processing on UEspeed-based functions and parameters.

Meaning: Indicates the number of handovers used to determine whether a UE in RRC-CONNECTED mode moves at a high speed during a specified period. This parameter is one of the key parameters used for redirection of high-speed UEs, which are determined based on the number of handovers in a specified period. If the number of handovers of a UE is greater than the value of this parameter during the period specified by the SpeedEvaluatedPeriod parameter, the UE is identified as a high-speed UE and triggers a redirection to a high-speed frequency. This parameter applies only to LTE TDD cells. GUI Value Range: 1~16 Unit: None Actual Value Range: 1~16 Default Value: 3

Meaning: Indicates the period during which the number of handovers is used to determine whether a UE in RRC_CONNECTED mode moves at a high speed. If the number of handovers of a UE in an evaluation period specified by SpeedEvaluatedPeriod is greater than SpeedEvaluatedNum, the eNodeB determines that the UE moves at a high speed and initiates a measurement-based redirection to a highspeed frequency. If the number of handovers of the UE in the period is greater than or equal to SpeedEvaluatedNumForFastUe, the eNodeB determines that the UE moves at a fast speed. In this situation, if the UE has GBR bearers, the eNodeB initiates a handover for the UE to a frequency for which the SpeedMobilityTargetInd option of the MobilityTargetInd parameter is selected.

Indicates whether to enable compatibility solutions, based on which the eNodeB determines whether to handle compatibility issues. UECapRprtAbnormalCtrlSwitch: If this option is selected, the eNodeB handles compatibility issues of UEs that cannot report their capabilities. ApCqiRptAbnormalCtrlSwitch: Indicates whether to apply a compatibility solution to abnormal aperiodic channel quality indicator (CQI) reporting. If this option is selected, the compatibility solution takes effect. The configuration IEs related to aperiodic CQI reporting are always included in RRC Connection Reconfiguration messages used to reconfigure CQIs regardless of whether the IEs changed or not. If this option is deselected, the compatibility solution does not take effect. The configuration IEs related to aperiodic CQI reporting are not included in RRC Connection Reconfiguration messages used to reconfigure CQIs if the IEs remain unchanged. UeInterRatMeasCtrlSwitch: Indicates whether the eNodeB checks the QCI-specific inter-RAT handover policies when evaluating an inter-RAT handover. This function does not allow the eNodeB to deliver interRAT measurement configurations to some special UEs anymore and applies to the following types of interRAT handovers: coverage-based handover, distancebased handover, uplink-quality-based handover, service-based handover, and SPID-specific handover back to the HPLMN. If this option is selected, the eNodeB determines whether to deliver inter-RAT A1/A2, blind A1/A2, and inter-RAT B1/B2 measurement configurations to the UE for a measurement-based or blind inter-RAT handover based on the setting of the No handover flag parameters in the InterRatPolicyCfgGroup MO for QCIs of services running on the UE. If this option is deselected, the eNodeB does not perform the evaluation based on the values of the No handover flag parameters. VoipExProtSwitch: Indicates whether to enable service-request-based inter-frequency handover protection when a VoLTE exception occurs. If this option is selected and the eNodeB does not support VoLTE, the eNodeB can set up bearers for QCI-1 services and other services when both of the following

ApCqiAndAckAbnCtrlSwitch: Indicates whether to enable a workaround of problems that may occur when aperiodic CQI reports in 3-1 reporting mode and ACKs/NACKs are transmitted simultaneously in a cell. If this option is selected, the eNodeB performs preallocation for aperiodic CQI reports. If this option is deselected, the eNodeB performs CQI_ONLY scheduling on aperiodic CQI reports. UeSRSAntSelectCtrlSwitch: Indicates whether to disable antenna selection for SRS transmission. If this option is selected, antenna selection is disabled. This option applies only to LTE TDD. CaCqiAndAckAbnCtrlSwitch: Indicates whether to enable a workaround of problems that may occur when periodic CQI reports and ACKs/NACKs are transmitted simultaneously in a cell in CA. If this option is selected, the eNodeB sets the SimulAckNackAndCqiSwitch parameter to OFF for CA UEs. If this option is deselected, the eNodeB sets simultaneousAckNackAndCQI according to the predefined algorithm. RlcSnSizeSwitch: Controls the configuration of RLC sn-FieldLength during handovers. If this option is selected, the configuration of RLC sn-FieldLength in the target cell is the same as that in the source cell. If this option is deselected, RLC sn-FieldLength for the target cell takes the value configured at the target side. FddTddCaPcellDuplexFdd: Indicates whether the eNodeB regards that a UE supports FDD+TDD CA with an FDD cell serving as its PCell when the UE reports the FDD+TDD CA band combination but does not report IE tdd-FDD-CA-PCellDuplex-r12. If this option is selected, the eNodeB regards that the UE supports this type of CA. If this option is deselected, the eNodeB regards that the UE does not support this type of CA.

During coverage-based interfrequency handovers with VoipMeasFreqPriSwitch being on, the eNodeB selects and delivers the neighboring frequencies based on the frequency priorities when starting measurements. The eNodeB preferentially delivers the frequency with the highest priorities to VoIP UEs. If this parameter is set to 0, this neighboring frequency is not prioritized. GUI Value Range: 0~16 Unit: None Actual Value Range: 0~16 Default Value: 1
