2 Overview 2.1 Introduction The Multi-site Cell feature enables multiple subsites at different physical sites to be set to a logical cell. A subsite refers to a certain area physically covered by one or multiple RXUs that belong to the same baseband unit (BBU). Cell-level parameters on the number of TRXs and the number of frequencies are set to the same values for each subsite in a multi-site cell. When Multi-site Cell is enabled, the cell coverage is expanded through the combination of the continuous coverage areas provided by multiple adjacent subsites. NOTE: RXUs consist of radio frequency units (RFUs) and remote radio units (RRUs). Figure 2-1 describes the network topology for a multi-site cell.

Figure 2-1 Network topology for a multi-site cell

As shown in Figure 2-1, subsites 1 through n represent the coverage areas provided by the RXUs at different physical sites, and all these subsites belong to the same logical cell, that is, multi-site cell A.

2.2 Benefits The Multi-site Cell feature provides the following benefits:  

Improves the resource usage efficiency and reduces frequency requirements. Replaces traditional repeaters with multi-site cells, thereby effectively improving network quality and reducing interference caused by active power amplifiers.



Decreases the number of inter-cell handovers and cell reselections, thereby improving user experience on circuit switched (CS) and packet switched (PS) services.



Expands the valid coverage area provided by each subsite and increases the coverage efficiency of a multi-site cell, because fewer overlapping coverage areas are now required between subsites.

2.3 Specifications Site-level Capacity 

Maximum number of subsites supported by a single site: 36



Number of TRXs supported by a single site: Number of TRXs in a multi-site cell + Number of TRXs in a non-multi-site cell ≤ k where 

Number of TRXs in a multi-site cell = Number of TRXs per subsite x Number of subsites in a multi-site cell



The value of k varies with the RXU configured in a multi-site cell. When RXUs are configured in mixed mode, the smaller value is used. For example, if both RRU3008 V1 and RRU3926 are configured in a multi-site cell, the value 144 corresponding to RRU3008 V1 is used. Table 2-1 shows the mapping between RXUs and k values. Table 2-1 Mapping between RXUs and k values RXU

Cell-level Capacity For a multi-site cell, Om x n represents its specification: m TRXs/subsite x n subsites. A multi-site cell can be configured with a maximum of n subsites, with a maximum of m TRXs for each subsite. The specifications of multi-site cells vary depending on hardware. Table 2-2 describes the hardware required for different specifications of multi-site cells.

NOTE:  When a multi-site cell is configured with several different RXUs, the specification of the multisite cell equals the lowest among all specifications of these RXUs. For example, the specification of multi-site cell A, which consists of RRU3008 V1 and RRU3926, equals the specification of RRU3008 V1.  The number of TRXs configured for a CPRI chain/ring of a multi-site cell equals the number of both primary and secondary TRXs in the RXUs on the CPRI chain/ring.

RXU Cascading The RXU cascading specifications of a multi-site cell are as follows: The RRU3926 supports level-15 cascading. The cascading-support capabilities of other RXUs are the same as those in a common cell.

3 Technical Description The cell-level parameter settings (including the number of TRXs, frequencies, and channels configured) for all subsites in a multi-site cell are the same. The parameters are configured in the same way as that for configuring a common cell. Only the RACJACCLEV(BSC6900,BSC6910), PSRACJACCLEV(BSC6900,BSC6910), and OUTPUTPOWER(BSC6900,BSC6910)/OUTPUTPOWER1(BSC6900,BSC6910) parameters can be configured on the subsite level. The mobile services in a multi-site cell are processed differently from those in a common cell. In a common cell, an MS communicates with the only site. Whereas, in a multi-site cell, an MS communicates with subsites at different sites. For details about service processing in a multi-site cell, see 3.2 Service Processing.

In a multi-site cell, the signal transmission and reception in each subsite must be synchronized over the Um interface to prevent co-channel interference. For details about the synchronization, see 3.3 Synchronization of Subsites over the Um Interface. When an MS moves from one subsite to another subsite in a multi-site cell, inter-subsite transition, instead of an inter-cell handover, is triggered. This noticeably decreases the number of handovers and improves service quality. For details about the transition, see 3.4 Inter-Subsite Transition. A multi-site cell can be any of the following types depending on the RXUs used by the subsites: 

RRU multi-site cell: All the subsites in a multi-site cell use RRUs.



RFU multi-site cell: All the subsites in a multi-site cell use RFUs.



RFU+RRU multi-site cell: In a multi-site cell, some subsites use RFUs, and other subsites use RRUs.

Multi-site cells can be used together with distributed antenna systems and leaky coaxial cables flexibly. This provides coverage for residential areas, campus areas, high-speed railway lines, indoor space, rural areas, and other special scenarios. For details about these special scenarios, see 3.5 Networking.

3.1 Concepts

Figure 3-1 An example of a multi-site cell

NOTE: Figure 3-1 is used as an example. The TRXs marked in red are the primary TRXs, and the TRXs marked in black are the corresponding secondary TRXs. For example, TRX A in subsite 1 is a primary TRX, and the TRXs (TRX A) in other subsites are the corresponding secondary TRXs. Other primary and secondary TRXs in the multi-site cell can be identified in the same way. In Figure 3-1, multi-site cell A has five subsites (subsites 1 through 5) and four logical TRXs (TRXs A through D). The same logical TRX is configured in all the subsites in the cell.

TRX In a multi-site cell, TRXs are classified into primary TRXs and secondary TRXs. During channel activation, immediate assignment, random access, or handover access, secondary TRXs assist primary TRXs in selecting a TRX from an appropriate subsite as the serving TRX for an MS. The number of TRXs in a multi-site cell equals the sum of primary and secondary TRXs in the cell. For example, multi-site cell A shown in Figure 3-1 has 20 TRXs in total. 

Primary TRX Logical TRXs in a multi-site cell are called primary TRXs. The four primary TRXs in multi-site cell A are the TRXs A through D marked in red.



Secondary TRX Primary TRX A belongs to subsite 1. It is bound to other subsites through data configurations. TRXs (TRX A) marked in black are called secondary TRXs. Secondary TRXs can be considered as images of the logical TRXs. Primary TRX A has four secondary TRXs (TRX A).



Serving TRX A serving TRX refers to a TRX of the subsite that carries Um-interface services. For example, during MS initial access, the BSS selects the TRX with the optimal signal-to-noise ratio (SNR) as the serving TRX for the MS. A serving TRX is either a primary TRX or a secondary TRX.

Functions of the primary and secondary TRXs: Controlled by their corresponding primary TRXs, secondary TRXs perform cell management and service control, including selecting the serving TRX and activating channels.

Subsite A subsite refers to an area covered by one or multiple RXUs under the same BBU. Subsites are classified into primary subsites and secondary subsites. Data configuration for Multi-site Cell on the BTS requires support from both the primary and secondary subsites. 

Primary subsite Among all the subsites in a multi-site cell, a subsite is specified as the primary subsite, for example, subsite 1 in Figure 3-1.



Secondary subsite All the subsites except the primary subsite in a multi-site cell are secondary subsites, for example, subsites 2 through 5 in Figure 3-1. The primary and secondary subsites are specified by the ISMAINLOCGRP(BSC6900,BSC6910) parameter.

Functions of the primary and secondary subsites: During initial configuration, to add binding between primary and secondary TRXs, bind primary TRXs to the RXU of the primary subsite, and then bind the primary TRXs to the idle RXU channels of all secondary subsites. The TRXPN(BSC6900,BSC6910) parameter must be set to appropriate values. After the initial configuration is complete and the GBTS is activated, the GBTS dynamically allocates the primary TRXs that were bound to the primary subsite to different subsites.

3.2 Service Processing Uplink Service Processing All the subsites in a multi-site cell are ready to receive data. The TRXs in each subsite measure and demodulate the received uplink signals from time to time. Then, the secondary TRXs transmit the calculated signal-to-noise ratio (SNR), bit error rate (BER), and receive signal strength to the corresponding primary TRXs. The primary TRX then selects a TRX as the serving TRX based on the received data. The serving TRX transmits signals to the primary TRX, which then decodes the signals in the uplink. As shown in Figure 3-2, TRXs (TRX B) in subsites 1 and 2 measure and demodulate the received uplink signals, and the TRX B in subsite 1 transmits the measurement data to primary TRX B in subsite 2 through the BBU. Primary TRX B then selects TRX B in a subsite as the serving TRX based on the data. The serving TRX can be a primary or secondary TRX. For the MS and BSC, services are processed by the same logical TRX (TRX B) all the time.

Figure 3-2 Uplink service processing

Downlink Service Processing The BCCH TRXs in all the subsites in a multi-site cell are ready to transmit data. The primary TRX encodes downlink signals and then transmits the signals to other subsites in the multi-site cell. After performing modulation, all the subsites process the signals as follows:  

For BCCHs, SDCCHs, and PDCHs, the modulated signals are transmitted in all subsites. For TCHs, the modulated signals are transmitted in all subsites by default. You can adjust data processing methods by setting the PWRLOCATION(BSC6900,BSC6910) parameter. 

If this parameter is set to ALLPwrLoc(All Location TRXes be Turned On), the signals are transmitted in all the subsites.



If this parameter is set to OnlyCurPwrLoc(Only Current Working Location TRXes be Turned On), the primary TRX selects the previous serving subsite and the subsite with the best uplink SNR for transmitting signals.

As shown in Figure 3-3, downlink signals are sent to subsite 2, which accommodates primary TRX B. Subsite 2 encodes and then transmit the signals to subsite 1 through the BBU. Subsites 1 and 2 modulate and then send the signals to the MS by default.

Figure 3-3 Downlink service processing

3.3 Synchronization of Subsites over the Um Interface The subsites in a multi-site cell are synchronized over the Um interface. To synchronize the frames transmitted from each subsite, the BBU automatically calculates the transmission latency between itself and each subsite, then sends latency-related parameters to the subsites to offset the latency over the optical fiber. This ensures synchronous transmission and reception of user data in each burst, as shown in Figure 3-4.

Figure 3-4 Synchronization over the Um interface

3.4 Inter-Subsite Transition When an MS traverses the coverage area of a multi-site cell, the BSC does not trigger an inter-subsite handover. Figure 3-5 shows the details.

Figure 3-5 Inter-subsite transition

When an MS traverses across subsites in a multi-site cell, the transition from one subsite to another is a process of reselecting the serving TRX. Figure 3-6 is used as an example. Assume that TRX A in subsite 1 is the serving TRX, and the MS moves from subsite 1 to subsite 2. During the call, each subsite measures the uplink SNR and receive signal strength from time to time, then reports the data to the primary TRX. Based on the data, the primary TRX selects TRX A in subsite 2 as the new serving TRX. For the MS and BSC, the call is still processed by TRX A. Therefore, the service is not interrupted.

Figure 3-6 Reselection of the serving TRX

3.5 Networking A multi-site cell uses RFUs and RRUs to provide distributed network coverage. It can also work with distributed antenna systems and leaky coaxial cables to provide network coverage in special scenarios. The networking modes are described as follows:

Two- and Single-RRU Bidirectional Modes Two- and single-RRU bidirectional modes are used to provide network coverage for long and narrow areas, such as railway lines. Figure 3-7 is used as an example. In two-RRU bidirectional mode, two subsites are configured at each physical site, and each subsite is configured with an antenna radiating radio signals on one side. In two-RRU bidirectional mode, one subsite is configured at each physical site. The subsite is split into two lines by a power splitter, and each line is configured with an antenna radiating radio signals on one side.

Figure 3-7 Network coverage in two- and single-RRU bidirectional modes

The Multi-site Cell feature helps effectively resolve the problem that handovers frequently occur and the overlapping coverage area is large when high-speed railway lines use common cells for services. Railway lines are long and narrow areas. Therefore, deploy BTSs alternately on both sides along a railway line to ensure continuous network coverage for users on both sides of a train.

Distributed Network Coverage Distributed network coverage can be used in scattered areas. It can also be used in certain areas to serve blind spots or enhance network coverage. For example, distributed network coverage can be used in residential areas (for outdoor coverage), campus areas, and rural areas. Multi-site cells help

resolve repeater-related problems, such as poor network quality, unstable and imperfect monitoring, and inefficient and inconvenient maintenance. Figure 3-8 describes its network topology.

Figure 3-8 Network topology of distributed network coverage

When distributed network coverage is used in a residential area for outdoor coverage, multiple signal sources and their respective coverage areas are specified. This ensures even network coverage in the residential area and reduces the impact on areas beyond the coverage area. When distributed network coverage is used on a campus, a multi-site cell consists of areas that experience the tidal effect, for example, the teaching buildings where traffic is heavy in daytime and the dormitory buildings where traffic is heavy at night form a multi-site cell. In this way, traffic load is balanced by time, increasing the radio resource usage and reducing network construction cost. When distributed network coverage is used in rural areas:  

If the traffic is light, the TRX usage increases. If the traffic is heavy or network capacity needs to be expanded, a multi-site cell can be split into two or multiple multi-site cells or even into independent cells to ensure good network coverage in all areas. This helps implement smooth network capacity expansion.

In addition, if some areas have poor network coverage because of geographical conditions, extra subsites can be deployed to serve the blind spots or enhance network coverage in these areas.

Distributed Antenna System Multi-site cells can work with distributed antenna systems to provide good network coverage for indoor space and short tunnels. 

Indoor space Multi-site cells can work with distributed antenna systems to provide good network coverage for indoor space in multi-storey or large buildings. As shown in Figure 3-9, the signals transmitted from the BTS are evenly distributed inside a building using an antenna system, which includes the feeder, power divider, coupler, and antenna. This prevents any blind spot in the building.

Figure 3-9 Indoor distributed network coverage

The Multi-site Cell feature has the following benefits regarding indoor distributed network coverage:





Prevents the situation that trunk amplifiers or repeaters are used when indoor power sources are underpowered.



Prevents the BTS uplink sensitivity decrease due to increased noise, which is caused by repeaters and trunk amplifiers.



Resolves the problem that repeaters have poor network coverage and are difficult to monitor or maintain. Tunnels

With a distributed antenna system, the signals from the BTS can be evenly distributed into a tunnel. Distributed antenna systems are deployed in short tunnels. Distributed antenna systems or leaky coaxial cables are deployed in middle and long tunnels.

Figure 3-10 Distributed network coverage in tunnels

A short tunnel is characterized by short coverage distance and low traffic volume. Therefore, deploy distributed antenna systems only at the entrance and exit of the tunnel. This facilitates capacity expansion and device maintenance.

Leaky Coaxial Cable Leaky coaxial cables are typically used in middle and long tunnels.

Figure 3-11 Network coverage by leaky coaxial cables in tunnels

When an MS moves quickly through a middle or long tunnel, the requirement for the overlapping coverage distance for a successful handover is strict. The combined networking mode of multi-site cells with leakage coaxial cables resolves the preceding problem and implements smooth signal level variation in the overlapping coverage areas.



5 Network Impact 5.1 System Capacity None

5.2 Network Performance The Multi-site Cell feature expands the cell coverage area, increases the frequency usage efficiency, and reduces interference caused by frequencies serving adjacent cells. Assume that one subsite covers a distance of 3 km, a multi-site cell consisting of six subsites can cover a distance of 18 km. When an MS moves from one subsite to another, inter-subsite transition, instead of an inter-cell handover, is triggered. This significantly decreases the number of inter-cell handovers. Moreover, fewer overlapping coverage areas are now required between subsites. This expands the valid coverage area provided by each subsite and increases the coverage efficiency of a multi-site cell.

6 Engineering Guidelines

6.1 When to Use Multi-site Cell The Multi-site Cell feature can be widely applied to residential areas, campus areas, high-speed railway lines, tunnels, indoor space, and rural areas. For details, see 3.5 Networking.

6.2 Required Information 

Coverage areas, coverage routes, and population density. The number of required RXUs, subsites, and TRXs is planned based on the information.



Locations, sizes, and directions of obstacles that affect radio signals, and distribution of tunnels, bridges, rivers, and lakes along the routes. The distribution of required antennas is planned based on the information.



Existed radio coverage information along the routes, including network systems, frequency bands, frequencies, scrambling codes, and BTS distribution. Radio parameters are planned based on the information.



In BTS restructuring scenarios, collect the following information on the live network for data planning and configuration: 

RXU information, including the type, specifications, cabinet No., subrack No., and slot No. of the RXU, the number of carriers on the RXU.



Index of existed logical TRXs and the cabinet No., subrack No., and slot No. of the RXU that carries the logical TRXs.

6.3 Planning 6.3.1 RF Planning 

Residential areas Frequencies in 1800 MHz frequency band are preferentially used for network coverage in residential areas. It is recommended that single frequencies be preferentially configured to avoid conflicts with those configured for a macro network.



Campus areas A campus network covers a large area. It consists of multiple distributed cells and outdoor cells. Plan frequencies in 1800 MHz frequency band for indoor coverage and frequencies in 900 MHz frequency band for outdoor coverage. Frequency reuse is recommended for non-adjacent cells.



High-speed railway lines The frequencies for high-speed railway lines must be planned based on the entire network. It is recommended that backup frequencies and special frequencies, such as indoor coverage frequencies, be used.



Tunnels The frequencies for tunnels must be planned based on the entire network. Frequencies in a tunnel do not interfere with those out of the tunnel because tunnels adopt the sealed structure. Therefore, only the frequencies beside the entrance and exit need to be planned. Frequencies for tunnels must be planned in the same way as those for high-speed railway lines.



Indoor space Frequencies exclusively used for indoor coverage are planned. If the traffic is overly heavy in an indoor area with intensive coverage, it is recommended that some outdoor coverage frequencies also be planned for indoor coverage.



Rural areas

If Multi-site Cell is used for covering rural areas, an appropriate frequency planning method must be adopted based on the coverage and extension of a multi-site cell. Generally, there are plenty of frequencies for covering rural areas, and planning remotely-configured frequencies has little impact on the rural areas. When the cells served by a macro base station are combined into an omnidirectional cell, the combined macro base station is planned to serve the omnidirectional cell. If multiple macro base stations are combined into a multi-site cell, the frequency planning is affected. Specifically, the coverage of a single cell extends and the number of frequencies used decreases. However, the number of neighboring cells involved increases, and the number of available frequencies decreases, making frequency planning more complex.

6.3.2 Network Planning 

When this feature is enabled, more data needs to be transmitted between subsites, and higher Common Public Radio Interface (CPRI) bandwidth is occupied. In GSM/UMTS (GU) mode where GSM and UMTS TRXs coexist in the same module, only the dual star topology is supported.



The star topology is recommended for the BBU and subsites to ensure network reliability. For example, when a BBU supports six subsites, each subsite is connected to the BBU in a star topology, and communicates with the BBU through a CPRI port on the GTMU board. The RXUs configured for the same subsite can be cascaded.



The maximum distance between a CPRI port of the BBU and an RRU is 40 km. Configure a shorter distance to ensure consistent transmission latency.

6.3.3 Hardware Planning 

The DRFU, GRFU V1, and MRFU V1 do not support Multi-site Cell.



Among all main processing boards, only the GTMUb board supports RFU+RRU multi-site cells.



The CPRI chains/rings of the same multi-site cell can occupy only one universal baseband radio interface unit (UBRI) board.



The RXUs of a multi-site cell cannot be shared with other cells.



The CPRI chains/rings of a multi-site cell cannot be shared with other cells.



The RXU TX and RX modes must be consistent for all subsites.

 

In an RFU+RRU multi-site cell, connect the RFU to the GTMUb board, and connect the RRU to the UBRI board. Table 6-1 lists the rules for mixed RXU configuration in a multi-site cell. Table 6-1 Rules for mixed RXU configuration

RXUs configured in different subsites in a multi-site cell

6.4 Overall Deployment Procedure Figure 6-1 shows the overall procedure for deploying the Multi-site Cell feature.

Figure 6-1 Overall deployment procedure

The deployment using the LMT, which is similar to the deployment using the CME, is used as an example. For the detailed procedure using the CME, see Using the CME."

6.5.2 Feature Configuration Using MML Commands This section describes how to configure the Multi-site Cell feature using MML commands. Refer to the operations in 6.4 Overall Deployment Procedure and perform the following steps on the BSC LMT: 1.

Add primary and secondary subsites. 

To add a primary subsite, run the ADD BTSLOCGRP command with its parameters set as follows: 

Set Location Group No. to an appropriate value.



Set Is Main Local Group to YES(YES).

 

Set CS Min.Access Level, PS Min.Access Level, Output Power Unit, and Output Power to appropriate values.

To add a secondary subsite, run the ADD BTSLOCGRP command with its parameters set as follows: 

Set Location Group No. to an appropriate value.



Set Is Main Local Group to NO(NO).



Set CS Min.Access Level, PS Min.Access Level, Output Power Unit, and Output Power to appropriate values.

2. ADD BTSLOCGRP: IDTYPE=BYID, BTSID=0, LOCGRPNO=0, ISMAINLOCGRP=YES, RACJACCLEV=-109, PSRACJACCLEV=-109, OUTPUTPOWERUNIT=0_1dB, OUTPUTPOWER1=42.6; ADD BTSLOCGRP: IDTYPE=BYID, BTSID=0, LOCGRPNO=1, ISMAINLOCGRP=NO, RACJACCLEV=-109, PSRACJACCLEV=-109, OUTPUTPOWERUNIT=0_1dB, OUTPUTPOWER1=42.6; 3.

Add RXUs to the primary and secondary subsites. Run the ADD BTSRXU2LOCGRP command multiple times with Location Group No., Cabinet No., Subrack No., and Slot No. to appropriate values. ADD BTSRXU2LOCGRP: IDTYPE=BYID, BTSID=0, LOCGRPNO=0, CN=0, SRN=3, SN=0; ADD BTSRXU2LOCGRP: IDTYPE=BYID, BTSID=0, LOCGRPNO=1, CN=0, SRN=3, SN=1;

4.

Bind all logical TRXs in the primary subsite to idle RXU channels of secondary subsites. Run the ADD BTSBINDLOCGRP command multiple times. In this step, set Main Location Group No., Sub-Location Group No., TRX ID, Cabinet No., Subrack No., Slot No., and SubLocation Group TRX Board Pass No. to appropriate values.

NOTE:  This configuration takes effect only when the TRXs in the primary subsite are the same as those in secondary subsites. For example, in a multi-site cell with four subsites, subsite A is the primary subsite and is configured with three logical TRXs, and subsites B, C, and D are secondary subsites. In this situation, bind the three logical TRXs in the primary subsite to the idle RXU channels of subsites B, C, and D.  All the subsites under a BTS or cell will be deleted if the BTS or cell is deleted. ADD BTSBINDLOCGRP: IDTYPE=BYID, SLAVELOCGRPNO=1, TRXID=1, CN=0, ADD BTSBINDLOCGRP: IDTYPE=BYID, SLAVELOCGRPNO=1, TRXID=2, CN=0, 5.

BTSID=0, MAINLOCGRPNO=0, SRN=3, SN=1, TRXPN=0; BTSID=0, MAINLOCGRPNO=0, SRN=3, SN=1, TRXPN=1;

(Optional) To adjust the mode in which downlink signals are transmitted in subsites, run the SET GCELLSOFT command with Location Group Power Switch set to an appropriate value based on the network plan. NOTE: For details about how downlink signals are transmitted in subsites, see Downlink Service Processing. SET GCELLSOFT: IDTYPE=BYID, CELLID=0, PWRLOCATION=ALLPwrLoc;

Using the CME NOTE:  When configuring the Multi-site Cell feature on the CME, you must perform a single configuration first, and then perform batch modifications if required.  You must perform a single configuration for a parameter before batch modifications of the parameter. You are advised to perform batch modifications before logging out of the parameter setting interface. 1.

2.

Configure a single object on the CME. (CME single configuration) a.

Add a single BTS and a single cell. For details, see "Creating a Single GBTS" in 3900 Series Base Station Initial Configuration Guide.

b.

Configure the newly added cell as a multi-site cell. Then, set parameters on the CME configuration interface according to the operation sequence described in Table 6-3. For the method of performing the CME single configuration, see CME Single Configuration Operation Guide.

(Optional) Modify objects in batches on the CME. (CME batch modification center) To modify objects in batches, perform batch modification on the CME. Table 6-3 describes the batch modification support by different objects. In this step, right-click the BSC that accommodates the configuration object in the planned data area and choose GSM Batch Modification Center. Then, click the icon on the CME configuration interface to start the batch modification wizard. For the method of performing batch modifications through the CME batch modification center, press F1 on the wizard interface to obtain online help.

3.

Send the CME configuration data to the NE. For details, see "Exporting Deployment Lists and Configuration Files" in 3900 Series Base Station Initial Configuration Guide.

6.5.3 Activation Observation 1. 2. 3.

On the BSC LMT, start a Single User CS Trace task. For details, see "Tracing CS Domain Message of a Single Subscriber" in BSC6900 LMT User Guide or BSC6910 LMT User Guide. Use an MS to initiate a call in the test subsite. Check the tracing results in the Single User CS Trace window. Check in the Channel Activation message whether the subsite No., which is a hexadecimal number, is the same as the number of the tested subsite. Figure 6-2 shows an example. The hexadecimal number (0x20) marked in red indicates that the subsite No. is 32.

Figure 6-2 Subsite No.

6.5.4 Adjustment 6.5.4.1 Changing the Subsite That Accommodates a Primary TRX NOTICE: Change the subsite that accommodates the primary TRX only if necessary because this operation will interrupt services. The BTS automatically plans the primary TRXs in a multi-site cell based on load-related algorithms. To query or change the subsite that accommodates a primary TRX, perform the following operations on the BSC LMT: 

Run the DSP BTSLOCGRPMAINTRX command to query the subsite that accommodates the primary TRX.



Run the SWP BTSLOCGRPMAINTRX command to change the subsite that accommodates the primary TRX.

6.6 Performance Monitoring The running status of the base station subsystem (BSS) can be monitored by observing the subsitebased traffic statistics. For example, the distribution of traffic statistics in each subsite can be queried by observing the TK3104: Traffic Volume on TCH Carrying Traffic in One Location Group counter. The distribution of call drop causes in each subsite can be monitored by observing the subsite-based traffic statistics related to the TCH call drop rate. The subsite-based interference band distribution and main and diversity levels can be observed. The impacts of various interference on network quality can be reduced through analysis and troubleshooting. For details, see 6.8.2 Interference Detection. The TCH call drop rate and handover success rate in the BSS can be observed.

6.7 Parameter Optimization None

6.8 Troubleshooting 6.8.1 Automatic Switchover of the Primary and Secondary TRXs To ensure the normal operation of services, an automatic switchover of primary and secondary TRXs is triggered in any of the following scenarios: 

The subsite that accommodates the primary TRX is deleted when the BTS is working properly. (The primary subsite cannot be deleted when the BTS is working properly.)



TRX configuration errors occur, and all the TRXs with configuration errors are primary TRXs.



Software and hardware resources are unavailable in the subsite that accommodates the primary TRX. In this case, an RXU is faulty, CPRI connection is faulty, or the baseband processing board is faulty.

If any of the preceding conditions is met in a subsite, the BTS switches the primary TRX in the subsite over to another functional subsite.

6.8.2 Interference Detection When interference is detected by observing subsite-level traffic statistics on frequency bands, verify and troubleshoot interference-related problems using the following functions: 

Uplink frequency scanning



On the BSC LMT, run the SET GCELLFREQSCAN command to start uplink frequency scanning on the specified subsite or on all subsites.



On the Device Maintenance tab page, click Configure Frequency Scan to start uplink frequency scanning on the specified subsite or on all subsites.



Online and offline frequency spectrum scanning On the BSC LMT, click Monitor. On the displayed tab page, click Spectrum Scan Monitoring. In the displayed dialog box, perform either of the following steps: 

Select Frequency Time Domain Scan to start online frequency spectrum scanning on the specified subsite.



Select Off-line Spectrum Scan to start offline frequency spectrum scanning on the specified subsite.



Online intermodulation interference test and CDMA interference test NOTICE: The detection results will be unreliable if you perform dynamic data configuration (such as adding a TRX, deleting a TRX, or switching over primary and secondary TRXs) during an online intermodulation interference test or a CDMA interference test. On the BSC LMT, run the STR BTSRFTST command. 

If TSTTYPE is set to PIMONTRAFFIC(Traffic-based Intermodulation Interference Test), an online antenna passive intermodulation test is performed on the specified subsite or on all subsites.



If TSTTYPE is set to CDMAINTEF(CDMA Interference Test), a CDMA interference test is performed on the specified subsite or on all subsites.

To stop the test, run the STP BTSRFTST command. 

Idle timeslot test NOTICE: All idle timeslot tests in a multi-site cell will stop if you perform dynamic data configuration (such as adding a TRX, deleting a TRX, or switching over primary and secondary TRXs) during an idle timeslot test. 

On the BSC LMT, run the STR TRXBURSTTST command to start an idle timeslot test on the specified subsite or on all subsites. To stop the test, run the STP TRXBURSTTST command.



On the Device Maintenance tab page, click Testing Idle Timeslots to start an idle timeslot test on the specified subsite or on all subsites.
