Overview

2.1 Introduction BSS local switching is classified into BSC local switching and BTS local switching. BSC local switching is triggered when the BSC detects that the calling and called mobile station (MSs) of a call are under the same BSC. When BSC local switching is triggered, the speech signals are looped back on the BSC side. In addition, the signaling link on the MSC side is reserved, and the transmission resources on the Ater interface and the TC resources are released. BTS local switching is triggered when the BTS detects that the calling and called MSs of a call are under the same BTS, in the same BTS group, or in the same local switching area. When BTS local switching is triggered, the speech signals are looped back on the BTS side, in the BTS group, or in the local switching area. In addition, the signaling link on the MSC side is reserved, and the transmission resources on the Ater interface, the transmission resources on the Abis interface, and the TC resources are released. NOTE

A BTS group consists of one or more BTSs that share the same link and are controlled by the same BSC. Within a BTS group, the BTSs can be connected in a chain, star, or tree topology. A BTS can be considered as a group.

As shown in Figure 2-1 MS 1 (calling MS) and MS 2 (called MS) are under the same BSC; MS 3 (calling MS) and MS 4 (called MS) are under the same BSC. The speech signals are looped back to the MS on the BSC side. As a result, the BSC local switching is triggered, and the transmission resources on the Ater interface are released.

Figure 2-1 Loopback of speech signals in BSC local switching

As shown in Figure 2-2 MS 1 (calling MS) and MS 2 (called MS) are in the same BTS group; MS 3 (calling MS) and MS 4 (called MS) are under the same BTS. The speech signals are looped back to the MS in the BTS group or on the BTS side. As a result, BTS local switching is triggered in time division multiplexing (TDM) transmission mode, and the transmission resources on the Ater interface and some transmission resources on the Abis interface are released. NOTE

If the BSC6910 is used, the Ater interface and TC subrack are not involved.

As shown in Figure 2-3 the BTSs use IP transmission. MS 1 (calling MS) and MS 2 (called MS) are in the same local switching area, and MS 3 (calling MS) and MS 4 (called MS) are in the same local switching area. The speech signals are looped back to the MS on the IP BTS in the local switching area. As a result, BTS local switching is triggered in IP transmission mode, and the transmission resources on the Ater interface and some transmission resources on the Abis interface are released. NOTE

2 Overview

Figure 2-3 Loopback of speech signals in local switching area in BTS local switching

BSS local switching reduces the number of transmission resources required by a local call. Therefore, when BSS local switching is enabled, the number of transmission resources configured can be reduced, and the cost can also be reduced. In addition, BSS local switching eliminates the need of transcoding on the CN side. In this way, it reduces, especially in satellite transmission mode, the transmission delay of speech signals and improves the speech quality. BTS local switching and BSC local switching can be enabled independently or simultaneously. BSS local switching can be enabled only when the speech coding rate of the calling MS is the same as the speech coding rate of the called MS. BSS local switching applies to the following scenarios: l

The calling and called MSs of a large number of calls are under the same BSC or BTS. Enabling BSS local switching in this scenario helps save lots of transmission resources.

l

Network in remote areas Enabling BSS local switching for remote areas with insufficient resources helps save transmission resources.

l

Temporary coverage or emergent communication requirements

During a large gathering or site capacity expansion, local calls account for a large portion. Enabling BSS local switching allows these local calls to have sufficient resources. Issue 01 (2014-04-30)

NOTE

BSC local switching is performed on the BSS side without involving NEs on the NSS side. That is, the speech signals are not sent to the MSC. The transmission resources of sections D and E on the MSC side, however, are not released.

After BSC local switching is enabled, the speech signals are looped back to the BTS on the BSC side. In addition, idle frames are sent to the CN over the A interface board. In this way, the transmission resources of section C between the BSC and the TC are released, whereas the circuits occupied on the CN side are not released. As calls require fewer transmission resources, fewer transmission resources need to be configured, thereby reducing the network construction cost. NOTE

In virtual loopback, the BSC does not process the signals received from the CN and sends idle frames to the CN to ensure that the circuits occupied on the CN side are not released. This is to ensure that the circuits on the CN side are occupied.

To use only BSC local switching to save transmission resources on the Ater interface, set the BssLsGenMode parameter to BSCONLY(BSC Only). To preferentially use BSC local switching to save transmission resources on the Abis and Ater interfaces, set the BssLsGenMode parameter to BSCPRIORITY(BSC Priority), the ISSUPPORTBTSLSWITCH parameter to YES(Yes), and the BSCLSSTARTMODE parameter to an appropriate value.

3.2 Principles of BTS Local Switching When the SERVICEMODE(BSC6900,BSC6910) parameter for the Abis interface is set to TDM, BTS local switching is classified into the local switching under a BTS and the local switching in a BTS group. The local switching under a BTS is considered as the local switching in a BTS group that is comprised of one BTS. In the case of the local switching in a BTS group, the BSC automatically locates the BTS that is the nearest to the calling and called MSs and performs loopback on the BTS to save transmission resources. When SERVICEMODE(BSC6900,BSC6910) of the Abis interface is set to IP, BTS local switching is classified into the local switching under a BTS and the local switching between IP BTSs in a local switching area. The local switching under a BTS is considered as a special case of the local switching between IP BTSs in a local switching area. Local switching area refers to the area where the BTSs use IP transmission and connect to the same BSC. In addition, the BTSs in the local switching area can communicate with each other by using IP transmission. BTS local switching can be triggered only when both the calling and called MSs of a call are served by the BTS or BTSs in the same local switching area. The local switching area where an IP BTS enabled with local switching is located can be configured using the REGION(BSC6900,BSC6910) parameter. In a local switching area, the BSC sends the local switching message to the IP BTS. Based on the local switching message received, the IP BTS then changes the destination IP address to the IP address of the destination IP BTS to complete the loopback of the speech signals. Figure 3-2 shows BTS local switching. (GBFD-117702 BTS Local Switch)

Figure 3-2 BTS local switching

NOTE

BTS local switching is performed on the BSS side without involving NEs on the NSS side. That is, the speech signals are not sent to the MSC. The transmission resources of sections D and E on the MSC side, however, are not released.If the BSC6910 is used, the Ater interface and TC subrack are not involved.

After BTS local switching is enabled, the speech signals are looped back on the BTS to the MS, and idle frames are sent to the MSC on the A interface. In this case, the transmission resources of section B between the BTS and the BSC and the transmission resources of section C between the BSC and the TC are released, whereas the circuits occupied on the CN side are not released. To enable BTS local switching, set ISSUPPORTBTSLSWITCH(BSC6900,BSC6910) to YES (Yes). l

BSC6900 After the BTS local switching is enabled, set the BssLsGenMode parameter to determine the local switching priority policy. If the BTS local switching is only used to save transmission resources on the Abis and Ater interfaces, set the BssLsGenMode parameter to BTSONLY(BTS Only). If the BTS local switching is preferentially used to save transmission resources on the Abis and Ater interfaces, set the BssLsGenMode parameter to BTSPRIORITY(BTS Priority). If the BssLsGenMode parameter is set to BTSPRIORITY(BTS Priority), you also need to set the BTSLSSTARTMODE parameter to an appropriate value.

l

BSC6910 The BTS local switching uses a Huawei proprietary local switching mode, and therefore you need to set the BssLCLSMethod parameter to HuaweiPrivateLCLS(Huawei Private LCLS). The BSC6910 does not support BSC local switching, and therefore you need to

4 Procedures Related to BSS Local Switching

Procedures Related to BSS Local Switching

4.1 Triggering of the BSS Local Switching Call The triggering of a BSS local switching call involves the following procedures: checking the BSS local switching general strategy, detecting the BSS local switching call, checking the BSC/ BTS local switching strategy, and selecting the speech version for the BSS local switching call.

Checking the BSS Local Switching General Strategy After the called party answers the call or the incoming external inter-cell handover is complete, the BSC determines whether to enable BSC local switching or BTS local switching based on the setting of BssLsGenMode(BSC6900,BSC6910): l

The setting of BssLsGenMode indicates that BSC local switching is supported. BSC local switching can be triggered only when both the calling and called MSs do not meet the conditions specified by the parameters MsisdnSegList2AvoidBscLs1 to MsisdnSegList2AvoidBscLs10.

l

The setting of BssLsGenMode(BSC6900,BSC6910) indicates that BTS local switching is supported. BTS local switching can be triggered only when both the calling and called MSs do not meet the conditions specified by the parameters MsisdnSegList2AvoidBtsLs1 (BSC6900,BSC6910) to MsisdnSegList2AvoidBtsLs10(BSC6900,BSC6910). NOTE

The parameters MsisdnSegList2AvoidBscLs1 to MsisdnSegList2AvoidBscLs10 and MsisdnSegList2AvoidBtsLs1(BSC6900,BSC6910) to MsisdnSegList2AvoidBtsLs10 (BSC6900,BSC6910) are optional parameters. BTS local switching can be triggered only when the ISSUPPORTBTSLSWITCH(BSC6900,BSC6910) parameter of the BTS or of the BTSs in the BTS group is set to YES(Yes). BSC local switching can be triggered for an intra-BSC call only when the ISSUPPORTBTSLSWITCH parameter is set to YES(Yes) for the BTS serving the calling and called MSs.

Detecting the BSS Local Switching Call If BSS local switching can be triggered, the BSC starts the BSS local switching call detection to detect whether the calling and called MSs are under the same BSC. Issue 01 (2014-04-30)


12



Checking the BSC/BTS Local Switching Strategy If the calling and called MSs are under the same BSC, the BSC checks the settings of BscLsStartMode or BtsLsStartMode(BSC6900,BSC6910) to determine whether to trigger local switching. l

BSC local switching is triggered when either of the following conditions is true: – BscLsStartMode is set to UNCONDITIONALSTART(Unconditional Start). – BscLsStartMode is set to ATERCONGESTS(Start When Ater Congests), and the congestion rate on the Ater interface exceeds the value of AterJamThreshold2StartLs. – BscLsStartMode is set to PREFIXNUMBER(Start by Prefix Number), and either the calling MS or the called MS meets the conditions specified by parameters MSISDNPRFXLIST2STARTBSCLS1 to MSISDNPRFXLIST2STARTBTSLS10.

l

BTS local switching is triggered when either of the following conditions is true: – BtsLsStartMode(BSC6900,BSC6910) is set to UNCONDITIONALSTART (Unconditional Start). – In Abis over TDM transmission mode, BtsLsStartMode(BSC6900,BSC6910) is set to ABISCONGESTS(Start When Abis Congests), and the congestion rate on the Abis interface exceeds the value of AbisJamThreshold2StartLs(BSC6900,BSC6910). – BtsLsStartMode(BSC6900,BSC6910) is set to PREFIXNUMBER(Start by Prefix Number), and either the calling MS or the called MS meets the conditions specified by parameters MSISDNPRFXLIST2STARTBTSLS1(BSC6900,BSC6910) to MSISDNPRFXLIST2STARTBTSLS10(BSC6900,BSC6910). In IP transmission mode, BTS local switching can be triggered only when the calling and called MSs are served by the BTS or BTSs in the same local switching area. After an intra-BSC handover is complete, local switching detection is triggered only when BSSLSGENMODE(BSC6900,BSC6910) is set to BTSONLY(BTS Only) if the source cell and the target cell are under different BTSs. NOTE

Region Information specifies whether the BTS serving the calling MS and the BTS serving the called MS are in the same local switching area. If Region Information on the two BTSs is set to the same value, the two BTSs are in the same local switching area. For the BTS that works in IP transmission mode, BtsLsStartMode(BSC6900,BSC6910) is invalid.

Speech Version Selection for the BSS Local Switching Call Triggering BSS local switching requires that the calling and called MSs use the same speech coding rate. If they use different speech coding rates, the BSC can trigger forced switching to adjust the speech coding rate of one MS according to that of the other MS. If the adjustment fails, BSS local switching is not triggered. If the AMR feature is enabled, the calling and called MSs must use the same and constant speech coding rate. During the speech version selection of a BSS local switching call, the speech versions that are supported by both the calling and called MSs must be identified first. The speech version selection for the call complies with the following principles: l

Issue 01 (2014-04-30)

If the speech versions used by either MS of the call are supported by the other MS, the speech version selection follows the policies described in Table 4-1. Huawei Proprietary and Confidential Copyright © Huawei Technologies Co., Ltd.

l


If the speech version adjustment is forcibly initiated and not performed within the duration specified by WAITLOCALSWITCHFORHO(BSC6900,BSC6910), the local switching fails.

In the case of BSC local switching, if the calling and called parties use the same speech version, the BSC establishes a speech signal link, and the signal switching is performed in the BSC. After the signal switching is complete, the BSC releases the redundant resources on the Ater interface. NOTE

The speech signals are not sent to the MSC, and therefore the MSC cannot obtain the information about BSC local switching. To ensure the consistency of circuit resources with the MSC, the BSC does not release the circuit identification code (CIC) circuit.

In the case of BTS local switching, if the calling and called parties use the same speech version, the commands sent from the BSC to the BTS varies with the value of SERVICEMODE (BSC6900,BSC6910) for the Abis interface. l

If SERVICEMODE(BSC6900,BSC6910) of the Abis interface is TDM, the BSC sends a link setup command to the BTS. In this case, the speech signals are looped back on the Abis interface of the BTS or the BTS group. After the loopback is successful, the BSC releases the resources on the Abis and Ater interfaces. NOTE


l

If SERVICEMODE(BSC6900,BSC6910) of the Abis interface is IP, the BSC sends the IWF table to the BTS where the local switching needs to be performed. The BTS then locally loops back the speech frames based on the IWF table. After the loopback is successful, the BSC releases the resources on the Abis and Ater interfaces.

l

If the BSC does not receive the response message from the BTS within the duration specified by WAITCRDLCBTSLPCNF(BSC6900,BSC6910) after sending the link connection message or IWF table entries, the local switching fails.

4.2 Restoration of the BSS Local Switching Call Restoration of the BSS local switching call refers to the process by which a call in the local switching state is restored to a normal call. The restoration procedure for a BSC local switching call is different from the restoration procedure for a BTS local switching call.

Restoration of a BSC Local Switching Call When a BSC local switching call is handed over, the target cell may not support local switching or the outgoing BSC handover may fail. In this case, the BSC local switching call should be restored to a normal call before the handover. That is, the BSC needs to re-establish on the Ater interface the transmission channel used for carrying the speech signals sent to the MSC and then to the MS. Whether to restore a BSC local switching call is determined by the BSC without manual intervention or data configuration.

Restoration of a BTS Local Switching Call NOTE


Issue 01 (2014-04-30)


17



When a BTS local switching call is handed over, the TRX on which the target channel is located may not support local switching or the handover of a specific type may fail. In this case, the BTS local switching call should be restored to a normal call before the handover. The restoration procedure for a BTS local switching call varies with the setting of SERVICEMODE(BSC6900,BSC6910). l

When SERVICEMODE(BSC6900,BSC6910) of the Abis interface is set to TDM, the BSC sends a link setup command to the BTS to re-establish a channel on the Abis interface to transfer the speech signals from the Um interface. In addition, the BSC sets up a transmission channel on the Ater interface. Therefore, the speech signals can be sent on the transmission channel to the MSC and then to the MS.

l

When SERVICEMODE(BSC6900,BSC6910) of the Abis interface is set to IP, the BSC sends a local switching restoration command to the BTS to re-establish the route for the transmission of IP datagrams. In addition, the BSC sets up a transmission channel on the Ater interface. Therefore, the speech signals can be sent on the transmission channel to the MSC and then to the MS.

Whether to restore a BTS local switching call is determined by the BSC without manual intervention or data configuration.

4.3 Handover of the BSS Local Switching Call Intra-BSC Handover The intra-BSC handover of a BSS local switching call is similar to the intra-BSC handover of a normal call, except that the speech version for the BSS local switching call cannot be changed after the intra-BSC handover. That is, the speech version for the call must be constant before and after the handover. This restriction on the speech version may decrease the handover success rate and increase the call drop rate. For a BSC local switching call: l

If the intra-BSC handover is successful, the BSC local switching call may remain as a BSC local switching call, be converted to a BTS local switching call, or be restored to a normal call, depending on the support capability of the target channel for local switching.

l

If the intra-BSC handover fails, the BSC local switching call remains as a BSC local switching call.

For a BTS local switching call: l

If the intra-BSC handover is successful, the BTS local switching call may remain as a BTS local switching call, be converted to a BSC local switching call, or be restored to a normal call, depending on the support capability of the target channel for local switching.

l

If the intra-BSC handover fails and the BSC receives a handover detection message before the handover failure message, the BTS local switching call is restored to a normal call. Otherwise, the BTS local switching call remains as a BTS local switching call.

Outgoing External Inter-Cell Handover The procedure for the outgoing external inter-cell handover of a BSS local switching call is as follows: Issue 01 (2014-04-30)


18



1.

The BSC determines whether to initiate an outgoing BSC handover based on the handover algorithm and sends a handover request to the MSC.

2.

The MSC receives the handover request and sends a handover command to the BSC. l If the BSC receives the handover command from the MSC, the BSC instructs the peer MS of the handover initiating MS that the call is to be restored to a normal call. This ensures normal speech after the outgoing external inter-cell handover is successful. l If the BSC does not receive the handover command, the BSS local switching call remains as a BSS local switching call.

If the BSC receives a handover failure message from the MS, the BSC instructs the MS initiating the handover that the call is to be restored to a normal call.

Issue 01 (2014-04-30)

Service

Availability

Remarks

Ring Back Tone (RBT) service

Available

The RBT service is performed before the called MS answers the call, and therefore it is not affected by BSS local switching.

Call forwarding services

Available

The call forwarding services are performed before the called MS answers the call, and therefore such services are not affected by BSS local switching.

Call barring services

Available

The call barring services are performed before the called MS answers the call and are controlled by the MSC and HLR. Therefore, such services are not affected by BSS local switching.

Number identification service

Available

The number identification service is performed before the called MS answers the call, and therefore it is not affected by BSS local switching.

Unstructured supplementary service data (USSD)

Available

The USSD is not related to speech services, and therefore it is not affected by BSS local switching.

Speech-to fax service

Unavailable

Only the fax service can be performed. The fax service does not trigger BSS local switching. This service is available only when the Huawei CN equipment is used.

Independent billing of BSS local switching



Telecom operators can take the following measures to ensure the availability of those CN services that are affected by BSS local switching. l

To perform those CN services that become unavailable after BSS local switching is enabled, telecom operators can disable BSS local switching.

l

To perform those CN services that are conditionally available after BSS local switching is enabled, telecom operators need to deploy Huawei CN equipment. – When services such as announcement playing by the MSC and lawful interception are performed, Huawei MSC instructs Huawei BSC not to perform local switching or instructs Huawei BSC to convert a BSS local switching call to a normal call. – When the independent charging of BSS local switching calls is performed, Huawei BSC sends a message to the CN whenever Huawei BSC enables or disables BSS local switching. Based on the message sent from the Huawei BSC, the billing center starts or ends the charging of BSS local switching calls.

The preceding measures help reduce the impact of BSS local switching on CN services and decrease the application restrictions on BSS local switching.

Engineering Guidelines

l

In Abis over TDM mode, BTS local switching can be performed only after the Flex Abis feature is enabled. In Abis over IP mode, BTS local switching can be performed on calls served by the same BTS and on those served by different BTSs in the same local switching area. BSC local switching is supported in BM/TC separated mode.

l

In A over IP mode, BSS local switching is not supported.

l

In BM/TC combined mode, only BTS local switching is supported.

l

The implementation of BSS local switching may require the support from the MSC. When BSSLSMSCCOOP is set to BASIC(Basic Fun) or ENHANCED(Enhanced Fun), BSS local switching is controlled by the MSC as follows: – When BSSLSMSCCOOP is set to BASIC(Basic Fun) and the MSC does not allow the BSS local switching of a certain call, the BSC does not perform local switching on the call. – When BSSLSMSCCOOP is set to ENHANCED(Enhanced Fun) and the MSC does not allow the BSS local switching of a certain call, the BSC does not perform local switching on the call; when the MSC allows the BSS local switching of the call, the BSC performs local switching on the call. In addition, the MSC can charge the local switching calls independently.

l

If different types of BTSs are co-sited, BSS local switching can be enabled only when both the BTS software and the TRX software support it.

l

BTS local switching and BTS ring topology cannot be enabled for a BTS at the same time.

l

If the calling and called MSs are registered on two different MSCs, BSS local switching is not supported regardless of whether the two MSCs are connected to the same MGW or different MGWs.

l

If HDLC transmission is used, BSS local switching is not supported.

l The BSC works in BM/TC separated mode, and the Ater interface uses TDM transmission. l The BTSs participating in BSC local switching use the same transmission mode. l If different types of BTSs are co-sited, BSS local switching can be enabled only when both the BTS software and the TRX software support it. l If the calling and called parties are served by two MSCs that connect to the same or different MGWs, BSS local switching cannot be enabled. l If HDLC transmission is used, BSS local switching is not supported.

7.1.2 Precautions It is recommended that all cells under a BSC be configured with the same speech version and AMR coding rate set. This increases the success rate of local switching.

7.1.3 Activation Using MML Commands On the BSC LMT, perform the following steps: Step 1 Run the SET BSSLS command with its parameters set as follows: l Set BSS Local Switching General Strategy to BSCPRIORITY(BSC Priority) or BSCONLY(BSC Only). l Set Options for BSC Local Switch to an appropriate value. – To set Options for BSC Local Switch to ABISCONGESTS(Start When Abis Congests), you also need to specify Abis Jam Rate for BSC Local Switch. – To set Options for BSC Local Switch to PREFIXNUMBER(Start by Prefix Number), you also need to specify Prefix Number for BSC 1 to Prefix Number for BSC 10. l Set Avoid Number for BSC 1 to Avoid Number for BSC 10 based on actual conditions. Step 2 Run the MOD GCNNODE command to configure whether BSS local switching is performed by the BSC alone or by both the BSC and the MSC. l If the network plan defines that the BSC performs BSS local switching alone, set MSCCollaborated BSS Local Switching to NONSUPPORT(Not Support). Issue 01 (2014-04-30)
