Overview

In UMTS networks, circuit switched (CS) and packet switched (PS) services are processed in parallel, such as web browsing during a call. As defined in 3GPP Technical Specifications, DTM is used to support simultaneous CS and PS services in GSM or Enhanced Data rates for GSM Evolution (EDGE) networks. The DTM feature has been introduced in GSM networks to provide services similar to those provided by UMTS networks (3G-like services), attract more subscribers, and increase the average revenue per user (ARPU) for operators.

2 Overview

2.1 Introduction DTM is a standard function defined in 3GPP Technical Specifications and is applicable to class A MSs in GSM networks. DTM supports dual transfer mode in addition to dedicated mode, idle mode, packet idle mode, and packet transfer mode. A DTM-capable MS can have simultaneous CS and PS connections and process CS and PS services simultaneously. Subscribers can therefore send images or browse web pages during a call.

2.2 Benefits In UMTS networks, CS and PS services are processed in parallel. DTM enables GSM subscribers to enjoy services similar to those provided by UMTS networks. In addition, a GSM network can supplement a UMTS network in terms of coverage. Based on common DTM, Class 11 DTM doubles the uplink rate. Based on common DTM, HMC DTM triples the uplink and downlink rates. After DTM is enabled, the following applications can be introduced to create new revenue streams for GSM operators: l

Videophone Subscribers can enjoy uninterrupted data services, for which guaranteed bit rates (GBRs) are ensured, during a speech service.

l

Watching or downloading streaming programs Speech interaction or answering a call is now possible during web browsing. Subscribers may require circuit switched (CS) services while watching streaming programs. With DTM enabled, CS services can be performed without interrupting the streaming programs.

l

Sending images or videos during a call

Technical Description

3.1 DTM Multislot Capability The DTM multislot capabilities are independent of the currently defined 3GPP TS 45.002 multislot capabilities. Different MSs may have different DTM capabilities. When EGPRS or EGPRS2 is supported, the DTM multislot capability for EGPRS or EGPRS2 operation is indicated separately from the DTM multislot capability for GPRS operation. According to 3GPP TS 43.055, the DTM multislot classes are classes 5, 6, 9, 10, 11, 31-33, 36-38, and 41-44, and class 31 and higher classes are called HMC DTM. The higher the DTM multislot classes supported by the MSs and network devices, the higher the uplink and downlink data rates that can be supported. Incremental support is defined in the protocol to reduce the length of coding. With this support, an MS that supports a certain multislot class supports the less restrictive DTM multislot classes. Figure 3-1 and Figure 3-2 describes the incremental support of DTM multislot classes and HMC DTM multislot classes, respectively. The blue boxes indicate the DTM multislot classes, and the arrow indicates the compatibility direction. For example, if an MS supports class 11, the MS must support classes 10, 9, 6, and 5. If an MS supports class 33, the MS must support classes 32, 31, 11, 10, 9, 6 and 5. Figure 3-1 Incremental support of DTM multislot classes

Huawei BSCs differentiate channel allocation depending on DTM multislot classes: l

DTM channel allocation: intended for classes 5, 6, 9, and 10

l

Class 11 DTM channel allocation

l

HMC DTM channel allocation: intended for classes 31, 32, and 33

DTM Channel Allocation When SUPPORTDTM(BSC6900,BSC6910) is set to SUPPORT(Support), the BSC can allocate channels to MSs of DTM multislot classes 5, 6, 9, and 10. Class 6 maps onto DTM classes 5. Class 10 and higher map onto DTM class 9. For an MS of DTM class 5, the BSC can allocate only one PDCH on the uplink or downlink, that is, TCH + 1 PDCH (uplink) + 1 PDCH (downlink). For an MS of DTM class 9, the BSC can allocate a maximum of two PDCHs on the downlink, that is, TCH + 1 PDCH (uplink) + 2 PDCHs (downlink). TCH refers to traffic channels and PDCH refers to packet data channels. Figure 3-3 shows the DTM multislot models for classes 5, 6, 9, and 10.

Figure 3-3 DTM Multislot models for classes 5, 6, 9, and 10

Class 11 DTM Channel Allocation When CLASS11DTM(BSC6900,BSC6910) is set to SUPPORT(Support), the BSC can allocate channels to MSs of DTM multislot class 11. In addition to DTM multislot models for classes 5 and 9, an MS of DTM class 11 supports the following channel combination: TCH + 1 PDCH (downlink) + 2 PDCHs (uplink). An MS of DTM multislot class 11 better supports uplink-preferred services, such as uploading videos for sharing. Figure 3-4 shows the DTM multislot models for class 11. Figure 3-4 DTM multislot models for class 11 (uplink preferred services with the EDA feature enabled)

NOTE

After the EDA feature is enabled, the network allocates multiple uplink timeslots to an MS, and the MS monitors all the PDCHs corresponding to the allocated timeslots. If the MS detects that an uplink state flag (USF) is allocated to itself on an allocated PDCH, the MS can use the uplink blocks corresponding to this PDCH and other allocated PDCHs with larger timeslot numbers.

The DTM multislot models for class 11 are the same as those for classes 9 and 10 when any of the following conditions is met: l

Downlink-preferred services are performed.

l

Neutral services are performed.

l

The EDA feature is disabled.

HMC DTM Channel Allocation Class 31 and higher are called HMC DTM. When HMCDTM(BSC6900,BSC6910) is set to SUPPORT(Support),the BSC can allocate channels to HMC DTM services. An MS in a call can occupy a maximum of three PDCHs on either the uplink or the downlink. That is, the channels allocated to the MS can be TCH + 3 PDCHs (downlink) + 1 PDCH (uplink) or TCH + 1 PDCH (downlink) + 3 PDCHs (uplink). Figure 3-5 shows the DTM multislot models for class 31. Figure 3-5 DTM multislot models for class 31

Figure 3-6 shows the DTM multislot models for classes 32 and 33. Figure 3-6 DTM multislot models for classes 32 and 33 (uplink preferred services with the EDA feature enabled)

The DTM multislot models for classes 32 and 33 are the same as those for class 31 when any of the following conditions is met: l

Downlink-preferred services are performed.

l

Neutral services are performed.

l

The EDA feature is disabled.

3.2 DTM Channel Allocation Algorithm With DTM, the BSC can allocate channels to an MS in the combination TCH/F+PDCH or TCH/H+PDCH, where TCH/H refers to half-rate TCHs, and TCH/F refers to full-rate TCHs. Channel allocation in DTM mode must be in compliance with the DTM multislot capability of an MS. DTM CS services can adopt any of the supported speech coding schemes. Issue 01 (2015-04-20)


8



After obtaining the DTM multislot capability of an MS, the BSC allocates channels to the MS based on the following principles: l

The BSC chooses dynamic or static PDCHs and their adjacent TCHs as a candidate channel group according to the DTM multislot capability of the MS. Even if the number of PDCHs in the channel group does not meet the DTM multislot capability, the BSC still regards the channel group as a candidate channel group. TCHs in the candidate channel group can be idle or occupied by MSs that will enter DTM mode.

l

If the BSC finds occupied TCHs and their adjacent available PDCHs, the BSC preferentially allocates these TCHs and PDCHs to the MS.

l

If the BSC finds only idle TCHs and their adjacent PDCHs, the BSC preferentially allocates the channel group with the most PDCHs. If an MS is processing CS services before entering DTM mode, the BSC transfers the ongoing CS services to idle TCHs by using the DTM assignment procedure rather than the handover procedure.

l

If DTMOptiSwitch(BSC6900,BSC6910) is set to ON(On) and adjacent PDCHs do not meet the DTM multislot capability or no PDCH is adjacent to TCHs, the BSC dynamically converts idle TCHs to PDCHs. The BSC then allocates the PDCHs that meet the DTM multislot capability to the MS for DTM services. If multiple channel groups meet the DTM multislot capability, the BSC preferentially allocates the TCH occupied by the MS and PDCHs adjacent to this TCH.

Issue 01 (2015-04-20)

When DTMOptiSwitch(BSC6900,BSC6910) is set to ON(On), the BSC allocates channels for DTM services according to the policies specified by the DTMCSAllocPolicy(BSC6900,BSC6910) parameter. The weights of factors indicated by the values of DTMCSAllocPolicy(BSC6900,BSC6910) are as follows: –

DTMMULTI(Allocation): Multislot capability requirement of DTM PS services > Capacity requirement of DTM CS services > Quality requirement of DTM CS services > Management requirement of DTM CS services

–

CAPACITY(Capacity): Capacity requirement of DTM CS services > Multislot capability requirement of DTM PS services > Quality requirement of DTM CS services > Management requirement of DTM CS services

–

QUALITY(Quality): Quality requirement of DTM CS services > Capacity requirement of DTM CS services > Multislot capability requirement of DTM PS services > Management requirement of DTM CS services

–

MANAGEMENT1(Management 1): Management requirement of DTM CS services > Multislot capability requirement of DTM PS services > Capacity requirement of DTM CS services > Quality requirement of DTM CS services

–

MANAGEMENT2(Management 2): Management requirement of DTM CS services > Capacity requirement of DTM CS services > Quality requirement of DTM CS services > Multislot capability requirement of DTM PS services

When DTMOptiSwitch(BSC6900,BSC6910) is set to ON(On), the BSC preferentially allocates TCH/Hs or TCH/Fs for DTM services according to the policies specified by the DTMCSVersionPolicy(BSC6900,BSC6910) parameter. If the BSC preferentially allocates TCH/Hs for DTM services, the DTM service capacity can be improved. If the BSC preferentially allocates TCH/Fs for DTM services, the speech quality of DTM services can be ensured. If the policies specified by DTMCSVersionPolicy(BSC6900,BSC6910) conflict with those specified by other parameters, the BSC follows the policies specified by other parameters. For example, if the core network does not support TCH/Hs but DTMCSVersionPolicy(BSC6900,BSC6910) specifies that TCH/Hs are preferred, the configuration of DTMCSVersionPolicy(BSC6900,BSC6910) does not take effect. If Huawei Proprietary and Confidential Copyright © Huawei Technologies Co., Ltd.

TCH/Hs are required to improve cell capacity but DTMCSVersionPolicy(BSC6900,BSC6910) specifies that TCH/Fs are preferred, the configuration of DTMCSVersionPolicy(BSC6900,BSC6910) does not take effect. l

l

When DTMOptiSwitch(BSC6900,BSC6910) is set to ON(On) in a concentric cell: –

If the BSC expects to allocate channels in the overlaid (or underlaid) subcell for both CS and PS services, the BSC preferentially allocates these channels for DTM services according to the subcell in which TCHs are allocated for CS services.

–

If the BSC expects to allocate channels in the overlaid subcell for CS services and channels in the underlaid subcell for PS services, the BSC rejects the DTM requests from the MS and processes only CS services. This also occurs if the BSC expects to allocate channels in the underlaid subcell for CS services and channels in the overlaid subcell for PS services.

When DTMOptiSwitch(BSC6900,BSC6910) is set to OFF(Off) and IUODTMAccPolicy(BSC6900,BSC6910) is set to CSLayerOnly(CS Layer Only) in a concentric cell: –

If the BSC expects to allocate channels in the overlaid (or underlaid) subcell for both CS and PS services, the BSC preferentially allocates these channels for DTM services according to the subcell in which TCHs are allocated for CS services.

–

If the BSC expects to allocate channels in the overlaid subcell for CS services and channels in the underlaid subcell for PS services, the BSC rejects the DTM requests from the MS and processes only CS services. This also occurs if the BSC expects to allocate channels in the underlaid subcell for CS services and channels in the overlaid subcell for PS services.

l

When DTMOptiSwitch(BSC6900,BSC6910) is set to OFF(Off) and IUODTMAccPolicy(BSC6900,BSC6910) is set to AllLayers(All Layers) in a concentric cell, the BSC allocates channels for DTM services regardless of the subcell where CS services are processed. That is, DTM services can be initiated in the subcell where CS services are not processed. However, when this occurs, CS services must be migrated to the subcell where DTM services are processed.

l

When DTMOptiSwitch(BSC6900,BSC6910) is set to OFF(Off), and when CS services that occupied an SDCCH needs to request a TCH during the DTM procedure and channels adjacent to the idle TCH are not PDCHs, DtmTCHAllocOptSw(BSC6900,BSC6910) specifies whether the BSC is prohibited from allocating the TCH. –

If DtmTCHAllocOptSw(BSC6900,BSC6910) is set to ON(On), the BSC is prohibited from allocating the TCH. If there are PDCHs available, the BSC will initiate a PDCH reclaim procedure to establish DTM services.

–

If DtmTCHAllocOptSw(BSC6900,BSC6910) is set to OFF(Off), the BSC is allowed to allocate the TCH, and the BSC dynamically converts channels adjacent to the TCH to PDCHs for initiating the next DTM procedure.

After a DTM service connection is established, channels occupied by DTM services are processed according to the following principles: l

In DTM mode, a PDCH can be shared by MSs.

l

GPRS/EGPRS services in DTM mode can meet their QoS requirements.

l

If DYNCHNPREEMPTLEV(BSC6900,BSC6910) is set to LEVEL0(Preempt all dynamic TCHFs), LEVEL1(No preempt of CCHs), or LEVEL2(No preempt of service TCHF), channels occupied by DTM services can be preempted. In this case, CS services preferentially preempt non-DTM channels. This has the same impact as preempting other candidate channels or does not affect channel continuity.

Issue 01 (2015-04-20)


10



To protect PDCHs for DTM services during PDCH preemption, the DYNCHNPREEMPTLEV(BSC6900,BSC6910) parameter provides the following new policies:

l

–

LEVEL3(No preempt of dynamic PDCHs): CS services cannot preempt dynamic PDCHs that carry DTM services.

–

LEVEL4(No preempt of both dynamic PDCHs and CCHs): CS services cannot preempt dynamic PDCHs that carry DTM services or control channels (CCHs).

If high-priority CS services can preempt TCHs occupied by low-priority CS services and DTM CS services have low priorities, high-priority CS services can preempt TCHs occupied by DTM CS services. If multiple ongoing low-priority CS services in DTM and non-DTM modes have the same priority: –

When DTMOptiSwitch(BSC6900,BSC6910) is set to ON(On), high-priority CS services preferentially preempt TCHs occupied by CS services in non-DTM mode.

–

When DTMOptiSwitch(BSC6900,BSC6910) is set to OFF(Off), high-priority CS services randomly preempt TCHs occupied by CS services in DTM or non-DTM mode.

After a DTM service connection is established, if DTMIMMAPPLYSLAVEABIS(BSC6900,BSC6910) is set to ON(On), the BSC can immediately allocate more Abis bandwidth to the DTM call, improving the encoding performance of the DTM call. In contrast, the BSC allocates more Abis bandwidth to a common call only when the PS coding scheme used by the call changes. When both the DTM and BSS Local Switch features are enabled, set BssLsOptInDtmSw(BSC6900,BSC6910) to ON(On). When this parameter is set to ON(On), the BSS send a HANDOVER IND message to prohibit the peer-end call from changing Abis resources when the BSS Local Switch feature takes effect between a pair of calls and a call attempts to initiate a DTM service. This way, the number of call drops on TCHs due to equipment faults decreases.

3.3 DTM-Related Procedures 3.3.1 GPRS Signaling Transmission on the Main DCCH in Dedicated Mode When DTM is supported, the MS can send or receive GPRS signaling messages, such as GPRS mobility management (GMM) signaling messages generated during cell update or routing area (RA) update in CS dedicated mode. There are two methods of doing this. In the first method, the MS first enters the DTM to establish the uplink and downlink temporary block flows (TBFs). After transmitting GPRS signaling messages, the MS leaves the DTM and enters dedicated mode again. This method is time-consuming and decreases channel resource usage because PS resources must be requested first. In the second method, the main dedicated control channel (DCCH) is used to transmit GRPS signaling messages in dedicated mode, as shown in Figure 3-7. This method can accelerate the GPRS signaling transmission and improve the channel resource usage efficiency. When the MS is in dedicated mode, GPRS signaling messages are encapsulated as logical link control (LLC) protocol data units (PDUs) in compliance with LLC protocols, and then the LLC PDUs are sent to the radio resource (RR) entity for processing. The detailed procedure is as follows: Issue 01 (2015-04-20)


11



l

In the uplink, the MS encapsulates an LLC PDU in a new Layer 3 message. The Layer 3 message contains the protocol identifier GPRS Transparent Transport Protocol (GTTP). The MS sends the message using the existing Layer 2 mechanisms to the BSC over the main DCCH. The BSC extracts the Temporary Logical Link Identity (TLLI) and the LLC PDU, which are then encapsulated into a Base Station Subsystem GPRS Protocol (BSSGP) UL-UNITDATA.

l

In the downlink, upon receiving a BSSGP PDU, the BSC can identify whether the PDU contains signaling information. If the length of the LLC PDU meets length requirements and the BSS has an RR connection to the addressed MS with the international mobile subscriber identity (IMSI), the BSC sends the GPRS signaling message over the main DCCH.

Figure 3-7 shows GPRS signaling transmission on the main DCCH in dedicated mode. Figure 3-7 Using the main DCCH to transmit GPRS signaling in dedicated mode

GPRS signaling transmission on the main DCCH in dedicated mode has the following restrictions: l

The MS must be in dedicated mode rather than in DTM mode.

l

The main DCCH can transmit GPRS signaling messages, but not GPRS data.

l

The number of link access procedure on the Dm channel (LAPDm) frames disassembled from a GPRS signaling message must be smaller than the value specified by the network. The value is determined by MAX_LAPDm in SI6. MAX_LAPDm has three bits and its value ranges from 5 to 12. By default, MAX_LAPDm is 5.

3.3.2 DTM Establishment Uplink PS Establishment in Dedicated Mode In dedicated mode, if the BSS and MS support DTM, the MS can send a DTM Request message on the main DCCH to establish an uplink PS connection. If the BSS does not need to re-allocate CS resources (that is, the BSS uses the original TCH to carry speech in DTM mode), it sends a Packet Assignment message to allocate PS resources to the MS. Figure 3-8 shows the procedure. Issue 01 (2015-04-20)


12



Figure 3-8 Uplink PS establishment in dedicated mode without reallocating CS resources

If the BSS needs to reallocate the CS resources when allocating PS resources (DTM channel allocation is not applicable due to existing channel distribution), the BSS sends a DTM Assignment Command message on the main DCCH to the MS after reallocating the CS resources. If the MS successfully establishes the new CS connection, it sends an Assignment Complete message on the new main DCCH, as shown in Figure 3-9. If the MS fails to establish the new CS connection, it sends an Assignment Failure message on the old main DCCH, as shown in Figure 3-10. Figure 3-9 Uplink PS connection establishment in dedicated mode with CS resources reallocated and new CS connections established

Figure 3-10 Uplink PS connection establishment in dedicated mode with CS resources reallocated and new CS connections failed

Downlink PS Establishment in Dedicated Mode In dedicated mode, if the MS is in the GMM Ready state, the BSS needs to establish a downlink TBF after receiving a downlink PDU from the SGSN. If the BSS does not need to reallocate CS resources, it sends a Packet Assignment message on the main DCCH to the MS. Figure 3-11 shows the procedure. Issue 01 (2015-04-20)


13



Figure 3-11 Downlink PS establishment in dedicated mode and GMM ready state

If the BSS needs to reallocate CS resources when allocating PS resources, the BSS sends a DTM Assignment Command message on the new main DCCH to the MS after reallocating the CS resources. If the MS successfully establishes the new CS connection, it sends an Assignment Complete message on the new main DCCH. If the MS fails to establish the new CS connection, it sends an Assignment Failure message on the old main DCCH. The procedure for reestablishing the downlink PS connection between network elements is the same as the procedure for reestablishing the uplink PS connection. If the MS is in dedicated mode and GMM standby state, the BSS sends a Packet Notification message on the main DCCH to the MS after receiving a packet paging message from the SGSN. The MS then sends an LLC frame as a response to the packet paging. The SGSN starts to send the downlink information after receiving the paging response from the MS. Figure 3-12 shows the procedure. Figure 3-12 Downlink PS establishment in dedicated mode and GMM standby state

CS Establishment in Packet Transfer Mode In packet transfer mode, the packet session must be aborted before the MS or the network initiates a CS connection request. When the CS connection is established, the MS enters dedicated mode. The PS connection is then established over the main DCCH occupied by the CS resources. This PS connection establishment procedure is the same as that for uplink or downlink PS connection establishment in dedicated mode.

3.3.3 DTM Release CS Release in DTM Mode In DTM mode, if the CS connection is released, the MS must release the PS resources. Issue 01 (2015-04-20)


14



PS Release in DTM Mode The procedure for releasing a TBF by an MS in DTM mode is the same as that for releasing an uplink or downlink TBF for common PS services. During CS services in DTM mode, if the last TBF is released by an MS, the MS enters dedicated mode.

3.3.4 Handover in DTM Mode The decision on when to change the serving cell of a DTM-capable MS is made based on the CS measurement report. In an intra-cell handover, the MS releases the PS resources and leaves DTM with the PS connection interrupted. Then, the MS enters dedicated mode on the new CS resource, reestablishes the PS connection, and enters DTM mode again. In an inter-cell handover, the MS releases the PS resources and leaves DTM with the PS connection interrupted. Then, the MS enters dedicated mode in the new cell, reads the system information messages, makes a cell update or RA update, reestablishes the PS connection, and enters DTM mode again. Figure 3-13 shows the procedure. Figure 3-13 Inter-cell handover in DTM mode

In DTM mode, more restrictions are imposed on CS handovers to retain the continuity of CS and PS services and to prevent CS handovers from interrupting PS services. When DTMCSHOOPTSW(BSC6900,BSC6910) is set to NO(No), CS handovers in DTM mode must be forced handovers, emergency handovers, or fast movement handovers. When DTMCSHOOPTSW(BSC6900,BSC6910) is set to YES(Yes), CS handovers in DTM mode caused by the following reasons are not allowed: l

Cell load sharing

l

Traffic sharing in a concentric cell or enhanced dual-band network

l

TCH/F-to-TCH/H handovers due to high cell load, TCH/F-to-TCH/H handovers due to insufficient Abis links, and TCH/H-to-TCH/F handovers due to low cell load

l

Handovers due to dynamic adjustment from TCH/F to TCH/H, from TCH/H to TCH/F, from TCH to SDCCH, and from SDCCH to TCH

l

Channel repacking

During establishment of a DTM service connection, links for CS services are established prior to those for PS services. After links for CS services are established and before links for PS services are established, the DTM call is in unstable state. Handovers triggered during this period must be delayed. If links for PS services fail to be established, DtmChOccupySupplyStatSw(BSC6900,BSC6910) controls whether to measure handoverrelated counters for CS services.

3.3.5 Cell Update, RA Update, and LA Update in DTM Mode If a DTM-capable MS is in dedicated mode, it can perform cell updates, RA updates, and location area (LA) updates on the main DCCH to reduce the load of packet resources. If LLC PDUs cannot be transmitted on the main DCCH, they are transmitted on TBFs. If both the RA and LA of a DTM-capable MS in idle mode change, the parallel RA and LA updates are performed. During the parallel RA and LA updates, either the RA update or the LA update can be complete first. l

If DTMUPDATEOPTITYPE(BSC6900,BSC6910) is set to SDCCH_REL_DELAY(SDCCH Release Delay), the BSC sends an RA Update Accept message to the MS on the SDCCH. If the BSC receives a DTM Request message on the SDCCH, the BSC delays releasing the SDCCH, as shown in Figure 3-14.

l

If DTMUPDATEOPTITYPE(BSC6900,BSC6910) is set to RAU_ACC_SEND_DELAY(RAU ACC Send Delay), the BSC sends an RA Update Accept message to the MS in downlink packet immediate assignment only after the SDCCH is released, as shown in Figure 3-15.

l

If DTMUPDATEOPTITYPE(BSC6900,BSC6910) is set to NO_DELAY(No Delay), the BSC releases the SDCCH and delivers the RA Update Accept message in a timely manner.

3.3.6 Paging Coordination The BSC can control the paging response of an MS using the paging coordination function rather than based on the setting of the NMO(BSC6900,BSC6910) parameter. This enables the MS to enter the DTM to establish CS and PS connections simultaneously. l

When an MS is in packet transfer mode, the BSC can send a CS Paging message on the PACCH even if the NMO(BSC6900,BSC6910) parameter is set to NMOII(Network Operation Mode II) or NMOIII(Network Operation Mode III). Therefore, the MS does not miss any CS Paging messages.

l

When an MS is in dedicated mode and the system supports DTM, the BSC sends a Packet Notification message on the main DCCH after receiving a PS Paging message. Therefore, the MS does not miss any PS Paging messages.

prevent an exception in DTM services. The VamosMainTsc(BSC6900,BSC6910) parameter specifies the primary TSC. Modifying an FH group TSC will reset a cell. If the FH group TSC is inconsistent with the primary TSC of VAMOS in the preceding scenario, the BSC uses the primary TSC as the TSC for the cell and automatically changes the FH group TSC to the primary TSC. This will cause the cell to automatically reset and therefore will cause CS and PS call drops. After the cell resets, the BSC allocates the primary TSC to all CS and PS services during initial access. To prevent VAMOS channel multiplexing on a DTM call (that is, the CS part of a DTM service), the BSC imposes the following constraints: VAMOS channel multiplexing can only be performed on a common CS call and on a DTM call. VAMOS channel multiplexing can be performed in only one direction, that is, the BSC assigns or hands over the common CS call to the channel occupied by the DTM call. If the call using the primary TSC is released during VAMOS channel multiplexing and the MS using the secondary TSC initiates a DTM service, since the packet data channel (PDCH) corresponds to the primary TSC, the MS using the secondary TSC needs to perform an intra-cell handover so that it can use the primary TSC before processing DTM services. This is because an MS using a new TSC cannot process DTM services, as stipulated in 3GPP TS 24.008 V9.7.0. For details about the VAMOS feature, see VAMOS Feature Parameter Description.

5.1 System Capability None

5.2 Network Performance l

Enabling DTM has no impacts on the performance of non-DTM PS services. The following KPIs remain unchanged after DTM is enabled except in case of many DTM users: Uplink TBF establishment success rate (non-DTM call) Downlink TBF establishment success rate (non-DTM call) Uplink TBF congestion rate (non-DTM call) Downlink TBF congestion rate (non-DTM call) Uplink TBF drop rate (non-DTM call) Downlink TBF drop rate (non-DTM call) TX.UP.GPRS.LLC.PDU.THRPUT.RATE.AVG and TX.UP.EGPRS.LLC.PDU.THRPUT.RATE.AVG for non-DTM calls TX.DOWN.GPRS.LLC.PDU.THRPUT.RATE.AVG and TX.DOWN.EGPRS.LLC.PDU.THRPUT.RATE.AVG for non-DTM calls

l

Enabling DTM has the following impacts on the performance of DTM PS services: –

In DTM mode, MSs must be allocated consecutive TCHs and PDCHs during channel allocation for DTM PS services. In addition, DTM calls are affected by users' behaviors. For example, when a CS release or CS handover occurs in DTM mode, the DTM service fails. The following KPIs deteriorate after DTM is enabled compared with those for non-DTM PS services: Uplink TBF establishment success rate (DTM call) Downlink TBF establishment success rate (DTM call) Uplink TBF congestion rate (DTM call) Downlink TBF congestion rate (DTM call) Uplink TBF drop rate (DTM call)

When DTMOptiSwitch(BSC6900,BSC6910) is set to ON(On), using the optimized channel allocation algorithm for DTM services decreases the DTM TBF congestion rate. If the penetration rate of DTM-capable MSs is no more than 30% on a network, setting DTMOptiSwitch(BSC6900,BSC6910) is set to ON(On) has the following impacts: The TBF congestion rate for DTM services approaches that for non-DTM services. Both the uplink and downlink DTM TBF congestion rates relatively decrease by more than 50%. If the impacts of CS releases or CS handovers and the scenarios with many DTM users are not considered, the performance of other DTM services is similar to that of non-DTM services.

When DTMOptiSwitch(BSC6900,BSC6910) is set to ON(On), PDCH conversion may be required to meet the DTM multislot capability of an MS. As a result, the delay in establishing DTM PS connections may be prolonged.

Enabling DTM has the following impacts on the performance of CS services: –

Establishing DTM services will cause an increase in the number of PDCHs. The proportion of half-rate traffic increases and the high quality indicator (HQI) decreases with the increase in the number of PDCHs. If the DTM traffic volume is large, the number of PDCHs increases significantly. As a result, the proportion of half-rate traffic increases and the HQI decreases significantly.

–

When DTMOptiSwitch(BSC6900,BSC6910) is set to ON(On), PDCH conversion may be required to meet the DTM multislot capability of an MS. As a result, the delay in establishing DTM CS connections may be prolonged.

Enabling DTM has the following impacts on the BSC processing capability: The CPU usages of the DPU board with the GPCU logical type, and of the XPU board, both increase by a maximum of 5%. NOTE

The DPUc and DPUf boards are supported only by BSC6900.

Formula

Expected Result

Uplink TBF establishment success rate (DTM call)

Formula 1:

Using formula 1:

DTM.UP.TBF.ESTB.SUC C/ DTM.UP.TBF.ESTB.AT MP

The uplink TBF establishment success rate (DTM call) is lower than the uplink TBF establishment success rate (non-DTM call). The difference between the two values depends on the proportion of DTM calls initiated during short message services (SMSs) or mobile management (MM) services and the proportion of handovers performed during the initiation of DTM calls.

Formula 2: 1(DTM.UP.TBF.ESTB.FAI L.NO.CHAN.RES +DTM.UP.TBF.ESTB.FA IL.MS.NO.RESP)/ DTM.UP.TBF.ESTB.AT MP

Using formula 2: When DTMOptiSwitch(BSC6 900,BSC6910) is set to ON(On), the uplink TBF establishment success rate (DTM call) approaches the uplink TBF establishment success rate (non-DTM call).

If the BSC separately allocates PDCHs for EGPRS and GPRS services, configure some dynamic or static EGPRS PDCHs on multiple nonconsecutive TRXs to increase the throughput of EGPRS DTM LLC PDUs. If the EGPRS PDCHs are configured on one TRX or multiple consecutive TRXs, idle TCHs may be adjacent to fewer EGPRS Huawei Proprietary and Confidential Copyright © Huawei Technologies Co., Ltd.

PDCHs. If there are no consecutive PDCHs, EGPRS subscribers cannot perform DTM PS services and EGPRS services are degraded to GPRS services. This decreases the throughput of EGPRS services. l

When GPRS dedicated channels are configured, it is recommended that GprsPdchSynMode(BSC6900,BSC6910) be set to ON(On) so that the synchronization of GPRS PDCHs is accelerated. This avoids DTM establishment failures when no PDCHs are available due to low synchronization of GPRS PDCHs, thereby improving the DTM access success rate. You do not need to configure this parameter for EGPRS channels.

NOTICE The cell processing PS services resets when you adjust the GprsPdchSynMode(BSC6900,BSC6910) parameter. l

When DTMOptiSwitch(BSC6900,BSC6910) is set to OFF(Off) in a concentric cell, do not set IUOCHNTRAN(BSC6900,BSC6910) to CONVERT0(Only convert at UL) or CONVERT1(Only convert at OL) because these settings allow DTM PS services to be performed either in only the underlaid or overlaid subcell. However, DTM CS services may be performed only or preferentially in a subcell different from that specified by IUOCHNTRAN(BSC6900,BSC6910). This causes ping-pong handovers.

l

To increase the DTM establishment success rate and the LLC throughput rate of DTM services, set DTMOptiSwitch(BSC6900,BSC6910) to ON(On).

l

To increase the DTM CS service capacity, set DTMCSAllocPolicy(BSC6900,BSC6910) to CAPACITY(Capacity), in which case the DTM multislot capability and speech quality will not be optimal. To improve the speech quality of DTM CS services, set DTMCSAllocPolicy(BSC6900,BSC6910) to QUALITY(Quality), in which case the DTM CS service capacity and DTM multislot capability will not be optimal. To improve the DTM multislot capability and further increase the DTM PS service rate, set DTMCSAllocPolicy(BSC6900,BSC6910) to DTMMULTI(Allocation), in which case the DTM CS service capacity and speech quality of DTM CS services will not be optimal. NOTE

Modifying DTMCSAllocPolicy affects channel allocation for only DTM services.

l

To increase the usage efficiency of DTM channels and the DTM establishment success rate, set DTMCSVersionPolicy(BSC6900,BSC6910) to HRfirst(HalfRate first) so that DTM CS services are carried by TCH/Hs. To improve the speech quality of DTM CS services, set DTMCSVersionPolicy(BSC6900,BSC6910) to FRfirst(FullRate first) so that DTM CS services are carried by TCH/Fs. However, in this situation, the DTM access success rate and DTM establishment success rate decrease.

l

In DTM mode, it is recommended that DTMIMMAPPLYSLAVEABIS(BSC6900,BSC6910) be set to ON(On) to improve the encoding performance of DTM calls.

Meaning: Whether to measure handover related counters during DTM assignment. When this parameter is set to ON, if the MS fails to occupy the PDCH during DTM assignment, the BSC processes services following the normal handover procedure and measures the number of handover requests. If the BSC receives a Clear Command message from the MSC during DTM assignment, the BSC does not measure the number of handover requests, handover commands, and handover detection times. When this parameter is set to OFF, if the MS fails to occupy the PDCH during DTM assignment, the BSC does not measure handover requests. If the BSC receives a Clear Command message from the MSC during DTM assignment, the BSC measures the number of handover requests, handover commands, and handover detection times. GUI Value Range: OFF(Off), ON(On) Unit: None Actual Value Range: OFF, ON Default Value: ON(On)
