1 Overview of Data Configuration Airbridge BTS3606E&3606AE


1-2 Huawei Technologies Proprietary Issue 02 (2006-10-08)

1.1 Application Scopes Data configuration is required in the following situations:

Commissioning Data configuration is an important part of system commissioning. A complete set of BTS data is configured for a new BTS.

Optimization When the BTS is optimized for better performance, you need to modify some software parameters to improve the cell coverage, call proceeding, and handoff performance.

Expansion When any new BTS equipment is added to serve more subscribers, you need to configure the added equipment based on the existing configuration.

Upgrade When upgrading the BTS software or hardware to support new features, you need to configure the new features based on the existing configuration.

Modification When a change in the network operating environment leads to the modification of network planning, you may need to modify some attributes of the BTS or reconfigure all the BTS data.

1.2 Configuration Tools BTS data is configured by MML configuration commands. MML commands can be sent to the BTS control & clock module (BCKM) through a dedicated service maintenance system or Telnet. The service maintenance system is preferred because it has centralized maintenance features and it is easy to use.

Unless otherwise specified, all configuration operations in this manual are performed through the service maintenance system.

1.2.1 Service Maintenance System A service maintenance system may run on different workstations (WSs) of different networks. Accordingly, you can use the service maintenance system for data configuration in two ways, as described in Table 1-1.

Table 1-1 Operation methods for service maintenance system

Far-End Configuration Near-End Configuration

Environment The service maintenance system and the back administration module (BAM) are in the same TCP/IP network.

The service maintenance system and the BCKM Ethernet port of a certain BTS are in the same TCP/IP network. This BTS is called source BTS.




Preconditions The network between the service maintenance system and the BAM runs normally.

The BAM runs normally. The operation and maintenance link (OML) between the target BTS and the BAM is set up.

The WS has the operation authority.

The network between the service maintenance system and the BCKM of the source BTS runs normally.

The BAM runs normally. The OML between the source BTS and the BAM is set up.

The OML between the target BTS and the BAM is set up.

Instructions Log in to the BAM from the service maintenance system through the TCP/IP network.

Execute MML configuration commands on the service maintenance system.

Start the reverse maintenance function on the service maintenance system.

Log in to the BCKM IP address from the service maintenance system.

Execute MML configuration commands on the service maintenance system.

Unlike the Telnet, you can use the auxiliary functions provided by the service maintenance system to facilitate the centralized configuration of the whole base station subsystem (BSS). Therefore, the service maintenance system is recommended for data configuration.

For detailed instructions on how to use the service maintenance system, see the online help of the

service maintenance system. In the case of near-end configuration, the WS is connected to the BCKM of the source BTS through

crossover cables.

1.2.2 Telnet A WS may operate in different networks. Similarly, two methods to use the Telnet are available, as described in Table 1-2.

Table 1-2 Telnet operation methods


Environment The WS and the BAM are in the same TCP/IP network.

The WS and the BCKM Ethernet port of the BTS are in the same TCP/IP network.





Instructions Start the Telnet agent function on the service maintenance system.

Log in to the service maintenance system in Telnet mode.

Execute MML configuration commands through the Telnet.

Log in to the BCKM from the Telnet through the TCP/IP network.

Execute MML configuration commands on the Telnet.

Preconditions The BAM runs normally. The OML between the target BTS and the BAM is set up.

The WS has the authority to access the BAM.

The network between the WS and the BCKM is normal.

The BAM is operational. An OML between the source BTS and the BAM is set up.

An OML between the target BTS and the BAM is set up.

Feature You can perform centralized maintenance on each BTS under the BSC. But you cannot make use of the auxiliary functions of the service maintenance system.

Using the Telnet in this way does not require the support of the base station controller (BSC) and BAM. You can, however, maintain BTSs that connect only with the WS. You cannot make use of the auxiliary functions of the service maintenance system.

The operation instruction for Telnet maintenance is as follows:

Step 1 Start the proxy (only for the remote LMT).

On the service maintenance system, execute the following command:

STR BTSTELPROXY: BTSID, PORT;

Step 2 On the O&M terminal, select Start > Run to open the Run dialog box. In the dialog box, run telnet xxx.xxx.xxx.xxx.

The "xxx.xxx.xxx.xxx" stands for the destination for Telnet login. Depending on the O&M terminal that you are using, the value can be the following addresses:

For the local LMT, the destination is the IP address of the BCKM. For the remote BAM, the destination is the O&M IP address of BTS. For the remote LMT, the destination is the IP address and the port of the BAM.

Step 3 In the Telnet window, enter the user name and password.

>User name: system

>Password: system

HW CBTS>opnday

HW CBTS>

After this step, you can execute commands through the Telnet. The command opnday enables character association for command input.



Step 4 Stop the proxy (only for the remote LMT).

Step 5 Execute the command STP BTSTELPROXY: BTSID, CONFIRM=Y; on the service maintenance system.

----End

1.3 Configuration Modes You can configure the BTS data either online or using configuration files. Table 1-3 describes these two data configuration modes.

Table 1-3 Data configuration modes

Online Configuration File Configuration

Application scope

Regional modification of configuration data when the BTS is running normally.

System commissioning of the BTS.

Instructions Execute MML configuration commands one by one on the service maintenance system.

Using a file compiler, create a configuration file that contains all the BTS configuration information.

Save the configuration file in \cdma2000\BTSLoad\cfg in the BAM and name it correctly.

Execute the command DLD CBTSSW to load the configuration file to the target BTS and then activate the configuration file.

Remark Some configuration commands may cause temporary interruption of BTS services.

For details on how to load the configuration file, see the Airbridge BTS3606E&3606AE CDMA Base Station System Commissioning Guide.

The file name format of a configuration file is BTSXXX.txt. The XXX stands for the BTS ID.

1.5 MML Command Conventions The format of all BTS MML commands is as follows:

Command: Parameter 1 = Value 1, Parameter 2 = Value 2, Parameter n = Value n;

All MML commands described in this manual are subject to the following conventions:

For parameters with fixed values, both parameter ID and values are present. For parameters with variable values, only the parameter ID is present. Optional parameters that are generally set to default values are not shown in the MML

command.

For example, an MML command for setting the satellite card mode is written as follows:

SET CBTSCLKSRCMODE: BTSID, SATTP=CLK, MODTP;

Where:

BTSID and MODTP are set according to the actual situation. SATTP is set to the fixed value CLK. BTSNAME is optional and usually set to a default value. Thus, it is omitted in the MML

command.

For detailed information about parameters in MML commands, see the online help.

2 Configuring BTS Basic Information

About This Chapter


Title Description

2.1 Relevant Concepts Describes the concepts related with the configuration of BTS basic information.

2.2 Configuration Tasks Describes the tasks related to BTS basic information configuration.

2 Configuring BTS Basic Information Airbridge BTS3606E&3606AE



2.1 Relevant Concepts This section describes some concepts related to the configuration of the BTS maintenance information, BOOTP information, and cell resources.

2.1.1 OML Setup The physical transmission bearer between the BTS and the BSC can be E1/T1 or FE. The transmission mode over the physical bearer can be ATM or IP. The E1/T1 link can bear ATM or IP transmission. The FE link can bear IP transmission only.

Setting up an OML between the BTS and the BAM is the prerequisite for far-end BTS configuration. The setup of an OML varies according to the type of the bearer.

OML Setup in ATM over E1/T1 Mode When the transmission mode of the OML is ATM over E1/T1, the O&M IP address of the BTS is allocated through the Bootstrap Protocol (BOOTP). The BTS sets up an OML according to the BOOTP upon startup.

The process is as follows:

Step 1 The BTS sends a BOOTP request to the CDMA2000 system multiplexer unit (CMUX) of the BSC upon startup.

Step 2 The CMUX adds the information of BOOTP transmission channel to the BOOTP request frame and sends the request frame to the BAM. This information is called the BOOTP information. It is to be used as the hardware address of the client host.

Step 3 The BAM receives the BOOTP request and obtains the BTS ID from the BOOTP information.

You can execute the command ADD BTSBTPINFO to set the mapping between the BOOTP information and the BTS ID.

Step 4 The BAM obtains the BTS O&M IP address according to the BTS ID.

You can set the mapping between the BTS ID and the BTS O&M IP address using the command ADD BTS.

Step 5 The BAM fills information, such as the BTS O&M IP address, in the BOOTP acknowledgement frame and sends it to the BTS.

Step 6 The BTS receives the O&M IP address and then sends a TCP link setup request to the BAM.

Step 7 The BAM receives the request and then sets up an OML between the BTS and the BAM.

----End

OML Setup in IP over E1/T1 Mode The BTS uses two BOOTP requests to obtain the IP address of the BCIM, the route information, and the O&M IP address of the BTS.

For the BOOT process of the BCKM, refer to the section "OML Setup in ATM over E1/T1 ".

Step 1 During the startup of the BTS, the BCIM sends the BOOTP request to the CBPE in the BSC.



Step 2 With the BOOTP request, the CBPE obtains the IP address of the BCIM and the route information according to the information about the BOOTP transmission channel.

Step 3 The CBPE adds the IP address of the BCIM and other information to the BOOTP response frame and sends it to the BCIM.

Step 4 The BCKM sends the BOOTP request to the BSC to obtain the O&M IP address of the BTS.

Step 5 When the BTS obtains the O&M IP address, it sends the TCP link setup request to the BAM.

Step 6 The BAM accepts this request, and the BTS sets up the OML to the BAM.

----End

OML Setup in IP over FE Mode When the transmission mode of the OML is IP over FE, you cannot allocate the O&M IP address of the BTS through the BOOTP. You need to manually specify an O&M IP address for the BTS.

You need to define the IP address of the BCIM and the O&M IP address of the BTS only during the

first startup of a new BTS. For IP transmission over E1/T1 bearer, the IP interface board of the BSC is the CBPE. For IP transmission over FE bearer, the IP interface board of the BSC is the CBPF.


Step 1 Execute the command ADD CBTSFEPORT to set the IP address of the FE port on the BCIM.

Step 2 Execute the command SET CBTSBCIMIP to set the IP address of the BCIM.

Step 3 Execute the command ADD CBTSIPROUTE to set the route for the BCIM.

Step 4 Execute the command SET CBTSOAMIP to specify an O&M IP address for the BTS.

Step 5 When the BTS obtains its O&M IP address, it sends an IP link setup request to the BAM.

Step 6 After receiving this request, the BAM sets up the OML between the BTS and the BSC.

----End




2.1.2 BOOTP Information Table 2-1 lists the BOOTP information for the large-capacity BSC and small-capacity BSC.

Table 2-1 BOOTP information

BSC Type BOOTP Information

Slot number of the CLPC connected to the CMUX

Subslot number of the CLPC connected to the CMUX

Number of the optical port connected to the CMUX

BTS gateway IP address of the CMUX

Large-capacity BSC

BTS BOOTP ID

Subrack number of the CIPS connected to the BTS

IP address of the BTS maintenance gateway on the CMUX

Small-capacity BSC

BTS BOOTP ID

Because the BSC has active and standby CMUXs, one OML corresponds to two chunks of BOOTP

information. In the two chunks of BOOTP information, the BTS gateway IP address of the CMUX is the same as the BTS BOOTP ID. When a backup OML is required, you need to set four chunks of BOOTP information.

Normally, an OML does not need any backup. You need to set only two chunks of BOOTP information.

2.1.3 Cell and Sector In the CDMA system, usually a cell refers to the coverage area of a BTS. It is identified by a cell ID. A cell can be divided into one or several sectors, each of which has a sector ID. Table 2-2 lists the common cell configurations.

2.2 Configuration Tasks The basic configuration of the BTS3606E and BTS3606AE involves the following tasks:

Configuring the BTS maintenance and BOOTP information Clearing the BTS configuration data Configuring the BTS and cell basic information

2.2.1 Configuring BTS Maintenance and BOOTP Information

Objective Add a BTS to the BTS data of the BSC and create the BTS BOOTP information at the BSC so that you can operate and maintain the BTS at the BSC side.

This task is the first mandatory data configuration task for a new BTS. When you reconfigure or reload the BTS, this task is not required because the information concerned in this task is set on the BAM.

Board Description Backup Mode

BCKM The BCKM controls and manages the entire BTS3606E/BTS3606AE. It provides the following functions:

BCKM 0 is an active board, and BCKM 1 is a standby one.

If both the BCKMs are powered on at the same time, the BCKM in slot 0 serves as the active board and the one in slot 1 serves as the standby one.

If the two BCKMs are not powered on at the same time, the one that is powered on first serves as the active board and the other serves as the standby one.

Generally, the BTS3606E or BTS3606AE has only one BCKM, which is inserted into slot 0.

Active/standby

BCIM The BCIM implements the connection between the BTS and the BSC. It supports:

E1/T1 and FE transmission modes ATM and IP bearers IMA, UNI, Fractional ATM, Fractional IMA, PPP, and MLPPP link groups

If only one BCIM is configured, this BCIM is inserted in Slot 0.

Active/standby: BCIM 0 and BCIM 1

BCIM 2 and BCIM 3

CEM The Channel Element Module (CEM) is the collective name of the CCPM and CECM. A CEM slot can house either a CCPM or a CECM. The CCPM is the service processing board. It processes the service data on the forward and reverse channels. The CECM is a CDMA2000 1xEV-DO service processing board. It processes the CDMA2000 1xEV-DO service data on the forward and reverse channels. The following pairs of CCPMs can either work together in daisy chain mode to provide a resource pool or work individually to provide a resource pool:

CCPM 0 and CCPM 1 CCPM 2 and CCPM 3 CCPM 4 and CCPM 5

Each of CCPM 6–CCPM 9 works individually to provide a resource pool, and they can be connected only with the ODU. A QCK1 CCPM can be inserted in Slot 0–Slot 5. The CECM provides a resource pool individually. CECM 6–CECM 9 can be connected with ODUs.

Equipment Description

CMTR The CMTR modulates or demodulates, and up-converts or down-converts the baseband IQ signals.

CMPA The CMPA is a multi-carrier high power amplifier module. It is used to amplify the modulated RF signals output by the CMTR and to monitor power amplification alarms.

CDDU The CDDU consists of two RF transceiver duplex isolators and low pass filters. A CDDU couples and tests the transmitted and received signals.

IDFU The IDFU consists of one RF transceiver duplex isolator and low pass filter. A IDFU couples and tests the transmitted and received signals.




3.1.4 BTS3606AE RF Module Numbering The RFC of a BTS3606AE consists of six ODUs. Figure 3-5 shows the configuration of an RFC.

OMPA The OMPA is an outdoor multi-carrier high power amplification module. It is used to amplify the modulated RF signal and to monitor power amplification alarm.

ODFU The ODFU consists of a RF duplex isolator and a low pass filter. It provides coupling test for the transmitted and received signals.

3.1.5 CE Pool The channel element (CE) pool consists of a CCPM/CECM or a group of CCPMs that are in serial connection.

The CECMs only form independent CE pools.

When the CRDM is not configured, the BTS3606E/3606AE supports that each CCPM forms an independent CE pool or that the following pairs of CCPMs form CE pools in daisy chain mode:

CCPMs 0 and 1 CCPMs 2 and 3 CCPMs 4 and 5




The CCPMs/CECMs 6–9 only form independent CE pools and can be used only for ODU cascading. The CE pool used by a channel depends on the position of the CCPM/CECM, as shown in Figure 3-7.

Figure 3-7 Relation between channels and CEMs

CMTR 0 CMTR 2 CMTR 4 CCPM 5 CCPM 3 CCPM 1

Carrier 0

Carrier 1

Carrier 2

Carrier 0

Carrier 2

When the CRDM is configured, it implements the resource sharing between CCPMs. In this case, the CCPMs can flexibly form multiple CE pools in daisy chain mode. The CE pools used by the carriers are not determined by the positions of the CCPMs/CECMs, but distributed by the CRDM.

To add the CRDM in the subrack, run the following command:

ADD CBTSGENBRD: BTSID, BRDTP=CRDM, BRDID;

To configure the CE pool, run the following command:

ADD CBTSCPL: BTSID, CPLID, CPLMODE= STATIC;

3.1.6 Adaptive Filtering The CDMA system can convert the received narrowband interference into broadband noise, thus reducing the narrowband interference. The system, however, is still affected by the narrowband interference with high amplitude.

To solve this problem, the reverse channel adaptive filtering function is introduced. With this function, the TRM can analyze the received signals, automatically lock the high-amplitude



narrowband signals in the inband spectrum, and apply wave restriction to these signals. In this way, interference signals can be eliminated.

The adaptive filtering function can eliminate the narrowband signals effectively and is suitable for areas with poor reverse-channel radio environment. In areas with good radio environment, however, you must disable the adaptive filtering function to avoid the delay caused by this function.

You can execute the following command to disable the reverse interference adaptive filtering function:

SET CBTSSECTORPARA: BTSID, LOCALCELLID, LOCALSECTORID, CRRID, SECTORTP, MAXCELLR, PCM, SAFM;

The QCK2 CMTR supports adaptive filtering, while the QCK1 CMTR does not support this function.

3.1.7 Diversity Low-Noise Bypass Mode If two TRMs use the same CDDU, the diversity receive (RX) signal is amplified on two TRMs because of the cable connection. Hence, both of the diversity low-noise amplifiers must be bypassed so that the main diversity signals are amplified once only.

Figure 3-8 shows how the diversity low-noise bypass mode is implemented.

4 Configuring the BTS Clock Airbridge BTS3606E&3606AE



4.1 Relevant Concepts This section describes some concepts related to the BTS clock configuration.

4.1.1 BTS Clock Source In a CDMA system, the system time of each BTS must be synchronous.

Three types of clock sources are available for a BTS:

Board clock obtained by the BCKM from the satellite receiver External clock such as the building integrated timing supply system (BITS) connected to

the BTS and the external GPS receiver Internal clock

The precision of the board clock is the highest, and that of the internal clock the lowest. The clock source with higher precision enjoys higher priority over that with low precision.

Generally, the BTS uses the board clock. When configuring the board clock, you also need to configure the internal clock. Otherwise, the BTS services are interrupted during GPS failure.

You can set clock sources and their priorities using the command SET CBTSCLK.

The BCKM or HPCM is equipped with a global positioning system (GPS) receiver or a GPS/global navigation satellite system (GLONASS) receiver. According to the receiver type and other requirements, you can set the satellite receiver to work in GPS, GLONASS, or GPS + GLONASS mode using the command SET CBTSCLKSRCMODE.

4.1.2 Clock Coordination Between the BTS and the BSC The BTS3606E and BTS3606AE can use either the satellite clock source or the E1/T1 clock source, that is, the Abis clock source. The following are the points for attention in the configuration of these two clock sources:

For the satellite clock source, that is, the GPS/GLONASS, the BTS and the BSC both have their own satellite receivers. This enables the synchronization between the BTS and the BSC.

For the E1/T1 clock source, the BTS is synchronized with the BSC and uses the clock of the BSC.

4.1.3 Local Time The BTS can obtain the universal time coordinated (UTC) from the satellite synchronization system. To determine the local time based on the UTC, you can set the local time zone and adjustment minute (time offset) by using the command SET CBTSCLKPARA. You can also use this command to set the feeder length to compensate the transmission delay of the satellite antenna system.

If the daylight saving time (DST) must be used, you can set the start time and end time of the DST by using the command SET CBTSDAYLT.

5 Configuring BTS Networking Information Airbridge BTS3606E&3606AE



5.1 Relevant Concepts This section describes some concepts related to the configuration of BTS networking information.

5.1.1 Transmission Links and Logical Links In terms of layering, the Abis link is classified into the following concepts:

Logical link The logical link is a virtual link. It transfers control messages, service data, and O&M data between the BSC and the BTS. From the angle of logical link, the BSS is a star network with the BSC in the center.

Transmission link The transmission link is the physical link that carries various logical links. The networking of transmission links depends on the BTS networking.

5.1.2 Classification of Logical Links As shown in Figure 5-1, logical links include:

OML It is the IP over ATM (IPoA) link between the O&M unit (OMU) of the BCKM and the BAM. The BSC CMUX serves as an IP gateway.

Signaling link It is the IPoA link between the main control (MC) module of the BTS BCKM and the BSC CDMA2000 signal process unit (CSPU).

Traffic link It is the AAL2 link between the BTS CEM and the BSC CDMA2000 radio frame processing board (CFMR).

IP addresses in Figure 5-1 are for reference only. The actual IP addresses vary with the BTS.



5.1.3 Classification of Transmission Link Groups The BTS3606E and BTS3606AE support the following transmission link groups:

User network interface (UNI) Inverse multiplexing for ATM (IMA) Fractional asynchronous transfer mode (fractional ATM) Fractional IMA Point to Point Protocol (PPP) Multiple Point to Point Protocol (MLPPP)

Table 5-1 lists the link groups supported by different types of BCIMs.

Each transmission link group can contain one or more transmission links. Each transmission link corresponds to one E1/T1 or a portion of timeslots in an E1/T1.




5.1.4 BTS Networking and Configuration The BTS3606E and BTS3606AE support the following BTS network modes:

Star networking Cascading with ODUs Chain networking Tree networking Fractional ATM networking

Star Networking Figure 5-2 shows the star networking mode.

In this mode, you need to configure the transmission link and then the logical link for each BTS.

For the configuration method of the Abis interface, see 5.2.7 "Configuring the CDMA2000 1X Abis Interface" and 5.2.8 "Configuring the CDMA2000 1xEV-DO Abis Interface."

Chain Networking Figure 5-3 shows the topology of a chain network.

Figure 5-3 BTS chain networking

BTS BTS BTS



The BTS chain networking is implemented through the BTS transmission trunk function, which is a kind of virtual path (VP) switching. The VP switching applies to only ATM transmission. In this mode, the BTS transmission link uses UNI and IMA mode. The upper-level link connects a BTS with its upper-level BTS or BSC and carries the logical links between the BTS and its lower-level BTS.

The virtual path identifier (VPI) of the logical link varies with the BTS. The VPI of a BTS is fixed to 1, while the VPIs of its lower-level BTSs are switched to the lower-level link (the link connecting the BTS with its lower-level BTS) through the trunk transmission link.

Figure 5-4 shows how the VP switching is implemented.

In chain networking mode, you need to configure the Abis interface only for the lowest-level BTSs. For the other BTSs, you need to configure the information of the Abis interface and the lower-level BTSs. For the configuration method of a lower-level BTS, see 5.2.11 "Configuring the Information about Lower-Level BTS Connected in UNI or IMA Mode."

Tree Networking Figure 5-5 shows tree networking mode. The tree network is equivalent to a combination of several chain networks. Its configuration method is similar to that of chain networking.

Fractional ATM Networking When transmission resources are limited and the BTS capacity is not too large, fractional ATM networking is recommended. This networking mode applies to both ATM transmission and IP transmission.

In this mode, the BTSs are usually connected in a chain or a tree topology. An upper-level BTS only needs to set up a timeslot cross-connection between the upper-level links and the lower-level links, as shown in Figure 5-6.

For fractional IP networking, an upper-level E1/T1 is not used as a complete transmission link. It is divided into timeslots which are allocated to different BTSs. The upper-level BTS only needs to set up a time slot cross-connection.

In fractional networking mode, you need to configure the Abis interface only for the lowest-level BTSs. For other BTSs, you need to configure the information of the Abis interface and cascaded lower-level BTSs. For the configuration method of a cascaded lower-level BTS, see 5.2.12 "Configuring the Information about Lower-Level BTS Connected in Fractional Mode" and 5.2.13 "Configuring the Information about Lower-Level BTS Connected in PPP/MLPPP Mode."

When fractional ATM networking mode is used, only the fractional links occupying timeslot 1 support the auto link listening function.

ODU Cascading The BTS3606E or BTS3606AE can be connected with an ODU through the following ways:

When the CRDM is not configured, the QCK1CCPM/QCK1CECM uses optical fibers to connect with the ODU.

When the CRDM is not configured, the QCK2CCPM/QCK2CECM uses optical fibers or SFP cables to connect with the ODU.

When the CRDM is configured, it uses optical fibers or SFP cables to connect with the ODU.

Figure 5-7 shows the topology of ODU cascading.

In this mode, the ODU is configured as a sector carrier of the BTS3606E or BTS3606AE. For the configuration method of the cascaded ODU, see 5.2.10 "Configuring the ODU."

IP networking applies to complicated network structure and high bandwidth requirement. Therefore, it is an ideal data service bearer. IP networking is not recommended for services requiring short delay or low delay jitter. Among such services, a typical one is the voice service, including VoIP.

6.2 Configuration Tasks Describes the tasks of BTS parameter configuration.

6 Configuring BTS Parameters Airbridge BTS3606E&3606AE



6.1 Relevant Concepts This section describes some concepts related to the configuration of BTS parameters. The concepts mentioned in 6.1.1 "Resending and Life Cycle of Paging Message" to 6.1.9 "CDMA2000 1X Abis Signaling Link Flow Control" are applicable to the CDMA2000 1X services and the concepts mentioned in 6.1.10 "CDMA2000 1xEV-DO Layer-2 Acknowledgement" and 6.1.11 "Asynchronous Message Sending" are applicable to the CDMA2000 1xEV-DO services. For the details of the BTS parameters, refer to the online help of the service maintenance system.

6.1.1 Resending and Life Cycle of Paging Message

Paging Message Resending Some paging messages on the paging channel (PCH) and forward common control channel (FCCCH) need no acknowledgement from mobile stations (MSs). Hence, the BTS cannot determine whether to send these paging messages to MSs. To ensure that the paging messages are sent properly, the BTS sends these paging messages periodically according to the resending timeslots set at the BSC.

You can enable or disable message resending on the PCH and FCCCH using the command SET CBTSCDMA1XCTRLPARA.

Life Cycle of Paging Messages If the BTS keeps the paging messages on the PCH and FCCCH for a long time without sending them to MSs, these messages become invalid. In this case, the BTS must discard these paging messages to release BTS resources. The BTS can delete expired paging messages in the BTS message queue according to the paging message life cycle set at the BSC.

You can set the message life cycle for the PCH and FCCCH using the command SET CBTSCDMA1XCTRLPARA.

6.1.2 Short-Period Paging on FCCCH Some trunking services require fast setup of calls. To meet this requirement, the function of short-period paging on the FCCCH is used to shorten the access time of mobile-originated calls and mobile-terminated calls. This MS needs to support this function.

You can enable or disable the short-period paging on FCCCH using the command SET CBTSCDMA1XCTRLPARA.

6.1.3 GPM Combination When an MS operates in slotted mode, the BTS sends general paging messages (GPMs) in a specific slot to broadcast messages to the MS and notifies whether the MS is paged and whether to convert the slotted mode into the non-slotted mode.

The GPM combination function enables you to use only one message to broadcast messages to several MSs in a specific slot. In this way, the number of messages sent on the PCH in every unit time is decreased and the air interface resource is saved.



You can set the number of GPMs to be combined and those to be searched using the command SET CBTSCDMA1XCTRLPARA.

6.1.4 Transmit Power Adjustment of Forward Inband Signaling To ensure reliable transmission of the air interface signaling, the BTS can use the MAC-layer protocol to identify whether the received forward traffic frames contain the signaling frames. If the forward traffic frames contain the signaling frames, the BTS adjusts the transmit power according to the preset forward signaling gain to improve the signaling receiving reliability of the MS.

You can set the forward inband signaling gain using the command SET CBTSCDMA1XCTRLPARA.

6.1.5 Access Load Control The access load control function can:

Decrease the MS access rate to ensure the availability of system resources when the access load is heavy

Increase the MS access rate to shorten the access time when the access load is low


Step 1 The BTS reports the channel seizure ratio periodically.

Step 2 The BSC determines whether to adjust the access parameter PSIST (0-9) according to the reported access channel seizure ratio.

Step 3 If yes, the BSC activates the system message update process of the corresponding carrier and sends the PSIST (0-9) to the MS.

Step 4 The MS adjusts the access delay according to the PSIST.

----End

You can set whether the BTS3606E or BTS3606AE reports the access channel seizure ratio to the BSC using the command SET CBTSSIGSOFTPARA.

6.1.6 Forward Power Synchronization Forward power synchronization ensures that the ratio (At/Ap) of the forward traffic channel power to the pilot channel power is the same for different legs during soft handoff. The process is as follows:

Step 1 The BTS reports relevant data in reverse traffic frames.

Step 2 The BSC determines the adjustment method and the amount of adjustment according to reported data.

Step 3 The BSC delivers the adjustment method and the amount of adjustment in forward traffic frames.

Step 4 The BTS adjusts the forward power according to the adjustment method and the amount of adjustment.

----End




You can enable or disable the forward power synchronization function of the BTS3606E or BTS3606AE using the command SET CBTSSIGSOFTPARA.

6.1.7 Forward Load Control Forward load control aims to effectively implement the admission and load control on the forward traffic channel by measuring the system forward load correctly and promptly. When the system is overloaded, forward load control can:

Guarantee services for most subscribers at the minimum expense by reducing the forward transmission rate and limiting the power

Make the best use of the forward capacity Ensure the reliable and stable running of the system

Forward load control involves automatic threshold adjustment, power overload control, and power amplification protection.

Automatic Threshold Adjustment The admission thresholds of the running system are adjusted on a real-time basis using forward frame error rates (FERs). Admission thresholds are expressed as the ratios of the pilot power to the total carrier forward transmit power.

Power Overload Control When the traffic exceeds the admission threshold, the BSS controls the traffic by inhibiting:

Supplemental channel (SCH) setup (extension) Voice call setup Leg establishment during soft handoff Power increase of the carrier traffic code channel

Power Amplification Protection When the forward load increases continually to a certain value, the BTS CMTR automatically activates the amplitude limitation function to control the attenuation of output power to protect the power amplification.

You can set the forward load control function of the BTS3606E or BTS3606AE using the command SET CBTSSIGSOFTPARA.

6.1.8 Layer-2 Acknowledgement Layer-2 acknowledgement means the BTS acknowledges the access messages received at the link access control (LAC) layer. This function speeds up the MS access rate. The process is as follows:

Step 1 The BTS receives the MS access message and obtains the ARQ field from this message.

Step 2 If the ACK_REQ in the ARQ field is 1, the BTS sends the BS Ack Order message to the MS. The MSG_SEQ in the ARQ field is set to 111, indicating that this message is sent by the BTS. If the ACK_REQ is 0, the BTS does not process the message.



Step 3 The BTS sends the received access message to the BSC for processing.

----End

Layer-2 acknowledgement messages also support the resending function and life cycle.

You can use the command SET CBTSSIGSOFTPARA to set the Layer-2 acknowledgement resending time and life cycle. The Layer-2 resending and Layer-2 life cycle take effect when Layer-2 response is enabled.

6.1.9 CDMA2000 1X Abis Signaling Link Flow Control If the Abis signaling link is overloaded, a lot of signaling messages are discarded, so the call-drop rate increases. To ensure the success rate of connected calls, the BTS3606E and BTS3606AE can make use of the flow control function to directly interrupt the call origination process when the Abis signaling link is overloaded.

Flow control of the Abis signaling link is based on the CDMA2000 1X Layer-2 acknowledgement. You need to activate the Layer-2 acknowledgement when enabling the flow control function.

You can use the command SET CBTSSIGSOFTPARA to set the flow control function for the CDMA 1X Abis signaling link.

6.1.10 CDMA2000 1xEV-DO Layer-2 Acknowledgement The CDMA2000 1xEV-DO Layer-2 acknowledgement refers to the BTS acknowledgement of the MAC layer message transmitted on the access channel. This function speeds up the access rate of access terminals (ATs).

Layer-2 acknowledgement messages also support the resending function and life cycle.

You can use the command SET CBTSCDMADOCTRLPARA to set the Layer-2 acknowledgement resending time and life cycle.

6.1.11 Asynchronous Message Sending The BTS3606E and BTS3606AE supports resending and life cycle of asynchronous messages to enhance the message sending reliability and to increase the utilization rate of the air interface resources. You can set the resending times and life cycle of the asynchronous messages at the BTS. In addition, the BTS3606E and BTS3606AE can combine several asynchronous messages into a message package for transmission.

You can set the parameters that control the asynchronous message sending using the command SET CBTSCDMADOCTRLPARA.

6.2 Configuration Tasks Setting BTS software parameters involves the following tasks:

Setting CCPM chip parameters Setting CECM chip parameters Setting CCPM control parameters Setting CECM control parameters
