When the OMU is installed for the first time, the CM right is disabled by default, and theCM right is not checked if you run a configuration command. You can enable the CM right

through the SET CMCTRLSWcommand. Before you run a configuration command, youshould run this command to apply for CM right.

By default, the control switch of the data configuration rights is set to OFF. In thiscase, all users can perform data configuration of the BSC6900 through the LMT orM2000.

If the CM control right is in idle state or belongs to the current user, REQ CMCTRLcan be executed successfully. If the CM control right belongs to other users, thiscommand cannot be executed successfully.

When the control switch of the data configuration rights is ON, only one user has the dataconfiguration rights at a time.

After the data configuration is complete, you can release the data configuration rights byrunning the REL CMCTRLcommand. In this way, another user can run the REQ CMCTRLcommand to obtain the data configuration rights.

If the user with the data configuration rights exits the LMT, the data configuration rightsare released automatically. In this case, another user can also run the REQ CMCTRLcommand to obtain the data configuration rights.

Example:

FOC CMCTRL:;

REQ CMCTRL:;

SET CMCTRLSW: CTRLSW=OFF; LST CMCTRLSW:;

LCK CMCTRL: RSNDES=UPGRADE;

ULK CMCTRL:;

In effective mode

the data configured takes effect immediately on the subrack.

In ineffective mode

the data configured for the subrack takes effect only in the OMU and not on thesubrack.

In this case, you can run the SET CFGDATAEFFECTIVEcommand to set the modeto effective mode, run the FMT DATAcommand to generate the dataconfiguration file for the subrack, and then run the RST SUBRACKcommand toreset the subrack. In this way, the subrack can load the data configuration fromthe OMU so that the data takes effect on the subrack.

When a subrack is in ineffective mode, you cannot query, compare, or perform

CRC check on the data between the host and the OMU. In addition, you cannotconfigure the host data of the subrack.

When all the subracks are in non-effective mode, license verification is notperformed. When a subrack is switched from the non-effective mode to theeffective mode, the OMU checks whether the data configuration exceeds thelimitations of the license. If the data configuration exceeds the limitations of thelicense, the mode switching is not allowed.

If the OMU is newly installed, subrack 0 is in ineffective mode by default. If asubrack is newly added, it is in ineffective mode by default.

Example:

SET CFGDATAINEFFECTIVE: SRN=0; SET CFGDATAEFFECTIVE:;

Be careful with this command. After the operation, all data configured previouslycan not be restored.

After execute this command, license will be initialized so user should configuredata and activate the license file again.

It is general used in the data configuration for the first time for adding ormodifying the BSC with a big batch of data.

NOTE

1. For a BSC configured with a 1800 MHz cell, you cannot set the value of

"Freq.Band" to "PSC1900". For a BSC configured with a 1900 MHz cell, youcannot set the value of "Freq.Band" to "DCS1800".

2. After the value of Service modeis changed, the service modes of all subracksare changed accordingly at the same time. Therefore, you must reset all thesubracks.

3. For Interface tag, if the BSC needs to support GPRS services, EDGE services,AMR services, eMLPP services, inter-RAT handover, and A over IP mode,"GSM_PHASE_2Plus" is recommended.

Example

To set basic attributes of a BSC (Area Code = 021; CC = 86), run the following command:SET BSCBASIC: AreaCode=021, CC=86;

Signal point data format

When this parameter is set to "WNF", the SPC is expressed in the form of an integer number.

When this parameter is set to "DNF", the SPC is expressed in three segments. The number of bits

included in each segment depends on the setting of the signaling point code bits parameter.

When the signaling point code bits parameter is set to "BIT14", the number of bits

included in each segment is 3, 8, and 3.

When the signaling point code bits parameter is set to "BIT16", the number of bits

included in each segment is 4, 8, and 4.

When the signaling point code bits parameter is set to "BIT24", the number of bitsincluded in each segment is 8, 8, and 8.

Assume that the signaling point code bits parameter is set to "BIT14" and the SPC is expressed in

three segments 5-7-2. You can perform the following steps to convert this SPC to an integer: 1. Convert the value in each segment to a binary number and fill 0s into a segment if the

number of bits included in that segment does not meet the requirements. The binary

number of value 5 in the first segment is 101, which is of three bits. Thus, you need not

to fill 0s into the first segment. The binary number of value 7 in the second segment is

111. As previously stated, when the signaling point code bits parameter is set to "BIT14",

eight bits must be included in the second segment. Thus, the second segment is put as00000111. Accordingly, you can calculate the binary number of the value in the third

segment. The binary number of 5-7-2 is 101 00000111 010.

2. Convert this binary number to a decimal number. The decimal form of this binary

number is 10,298.

Example:

ADD OPC: NAME="MBSC NO1", SPX=0, NI=NATB, SPCBITS=BIT14, SPDF=WNF, SPC=H'A00,

RSTFUN=OFF, HOSTTYPE=SINGLEHOST;

DPC is used to address the peer element of BSC in SSN.7 network.

For one BSC:

A DSP can be configured only when the Originating signaling Point (OSP) is configured. The DSP code must be unique and cannot be the same as OSP code.

DSP type:

IUCS: indicates the IU interface CS control plane and user plane signaling point.

IUPS: indicates the signaling point of the IU interface PS control signaling plane.

IUR: indicates the signaling point of the base station controller that is connected to the RNC.

IUCS_ALCAP: indicates the signaling point of the IU interface CS user signaling plane.

IUCS_RANAP: indicates the signaling point of the IU interface CS control plane.

Remote cabinet is used for TransCoder Rack (TCR) for GSM.

Function

Use ADD SUBRACK to add a subrack during system initialization and capacityexpansion of the system.

Note

1. The Main Processing Subrack (MPS) applies the default system configuration.You do not need to add this subrack by running the MML command.

2. Before adding a subrack, ensure that the cabinet where the subrack is addedexits, and that the MPS works properly.

3. Each Extended Processing Subrack (EPS) needs to be equipped with a fanmonitoring communication board. The power distribution monitoring board can be

configured as required. Generally, only one EPS in a cabinet can be connected tothe power distribution monitoring board.

4. The actual board type in the subrack must be consistent with the configuredtype.The subrack number of the EPS/TCS must be consistent with that indicated bythe DIP switches.

5. The port on the SCU in the central subrack that is connected to the addedsubrack must be enabled.

6. The relation between the parameter Subrack No. and the parameter Cabinet No.is described as follows: Cabinet No. = Subrack No./3. Cabinet No. is the quotient ofthat formula.

Example:

ADD CAB: CN=1, CABT=NO;

ADD SUBRACK: SRN=2, SRName="test2", CONNPWR=NO, TYPE=EPS;

25/115

Note

1. This command cannot be used by port 0 and port 1 on the SCUa board configured in

the EPS subrack.

2. When configuring the OMU board in external mode, one can only enable the attributesof one port, either port 10 or port 11, on the SCUa board in subrack 0. In other cases,when the attributes of an even numbered port are set, the attributes of the neighboringodd numbered port will be automatically set according to the attributes of the evennumbered port. For example, if the attributes of port 2 on the SCUa board are set, theattributes of port 3 on the same board will be set accordingly.

3. When configuring the OMU board in external mode, one can only enable the attributesof one port, either port 6 or port 7, on the SCUb board in subrack 0. In other cases, whenthe attributes of an even numbered port are set, the attributes of the neighboring odd

numbered port will be automatically set according to the attributes of the even numberedport. For example, if the attributes of port 2 on the SCUb board are set, the attributes ofport 3 on the same board will be set accordingly.

4. You can perform settings in batches by running this command. If the subrack number,port number, and port switch are specified, you can modify the attributes of a specifiedport on an SCUa/SCUb board. If only the subrack number and port switch are specified,you can modify the attributes of all ports on the specified SCUa/SCUb board. If theattributes of a port on an SCUa/SCUb board cannot be modified, batch setting does nottake effect on this port. In addition, when the external OMU is used, setting the ports onthe SCUa board in subrack 0 in batches does not affect ports 10 and port 11, and settingthe ports on the SCUb board in subrack 0 in batches does not affect ports 6 and 7.

5. For the active and standby SCUa/SCUb boards, if you set the attributes of the port onone SCUa/SCUb board, those of the port on the other SCUa/SCUb boards are also set.

6. When the SCUa and SCUb board are installed in the same subrack, this command canonly be used to set the attributes of the ports on the board located in a specified slot.

If we use BM/TC separated mode, we should configure Ater interface data.

If the TCS is configured locally:

Configure an Ater connection path.

Run theADD ATERCONPATHcommand to add an Ater connection pathbetween the MPS and the TCS.

Optional: In TC pool mode, run theADD ATERE1T1command to add anAter connection path between the BSC6900 and the TC.

The Ater connection path is established on the EIUa/OIUa board of the BM subrack andthe EIUa/OIUa board of the TC subrack. The Ater connection path connects the BMsubrack to the TC subrack in the BSC. The Ater connection path exchanges the signalingdata, service data, and OM data between the BM subrack and the TC subrack.

UDP: User Datagram Protocol

The UDP is a connectionless and unreliable transmission protocol.

The UDP provides simple services for the application layer. With the UDP, the data packet istransmitted from one end to the other end, but the data packet may not be transmitted tothe destination successfully. Any reliability required must be provided by the applicationlayer.

The UDP is a simple data packet-oriented protocol at the transport layer. The UDP is widelyused because it features low cost and high real-time performance during the transmission.The UDP is applied to scenarios that do not require high reliability.

SCTP: Stream Control Transmission Protocol

The SCTP is a reliable transmission protocol applied to network layers above theconnectionless network (such as IP network).The functions of the SCTP are similar to thoseof the TCP.

The SCTP is designed to transmit Public Switched Telephone Network (PSTN) signaling in

the IP network. In addition, the SCTP can be applied to other scenarios. Currently, the SCTPis used as the reliable transmission protocol to transmit signaling in the IP network.

The SCTP is the enhancement and optimization of the TCP with regard to signalingtransmission. Compared with the SCTP, the TFP has the following disadvantages: The TCPdoes not support the SCTP multi-homing function, which affects the availability; the TCP issubject to distributed denial of service (DDoS) attack, which affects the security; The TCPprocesses the packet in a strict sequence, but the delay is increased when processingpackets that are out of sequence. The SCTP supports the multi-homing function, whichimproves the link availability. In addition, the SCTP provides optimal performance in securityand packet processing.

The SCTP provides a reliable transmission of messages between equivalent SCTP users. TheSCTP is an end-to-end and connection-oriented protocol, which transmits data in

independent sequenced streams through the SCTP association between two SCTPendpoints.

M3UA Link

M3UA links are contained in an M3UA link set. The numbers of M3UA links range

from 0 to 63.

An Iu-PS interface requires at least one M3UA link. It is recommended that morethan one M3UA link be planned.

M3UA links are carried on SCTP links. It is recommended that the SCTP links areevenly distributed to the SPUa subsystems in the RSS subrack or an RBS subrack sothat the signaling exchange can be reduced between the SPUa subsystems.

IP Path

An IP path is a group of connections to the adjacent node. The path IDs rangefrom 0 to 65535.

Use this command to set attributes of an Ethernet port on the FG2a, GOUa, FG2c, and GOUc boards.

Auto negotiation

When the FG2a/FG2c board is used and the port type is GE, the default of the local self-negotiation

mode is adopted.

If the self-negotiation mode is adopted, the FE port rate, working mode and flow control mode

must be in accordance with the negotiation result. If the self-negotiation mode is not adopted, theFE port rate, working mode and flow control mode must be specified. Make sure that the specified

attributes are the same as that of the peer. Otherwise, transmission failure must be incurred.

If the self-negotiation mode is adopted on the local system, the peer must use the self-negotiation

mode.

Note

1. For the FG2a board, only Ethernet ports 0 and 4 can be set to GE ports. If Port typeof port 0 isset to "GE", you cannot configure attributes of ports 1-3; if Port typeof port 4 is set to "GE", you

cannot configure attributes of ports 5-7.

2. For the FG2c board in non-auto negotiation mode, if Port typeis set to "FE", the value range of

Port No.is 0-11; if Port typeis set to "GE", the value range of Port No.is 0-3. In auto negotiation

mode, the value range of Port No.is 0-11.

3. For the FG2a board, If ports 1-3 and ports 5-7 are configured with IP addresses, you cannot setPort typeof port 0 and port 4 to GE.

4. If the board works in active/standby mode, Slot No.can only be the logic slot number of theactive board.

5. This command is not mandatory. After the board is started, parameters of this command areconfigured by default. Either this command or the commandADD ETHIPcan be executed first.

The Gb interface (Gb interface is the interface between the SGSN and PCU in Huawei GPRSnetwork) is used to implement packet data transmission, mobility management and sessionmanagement between the SGSN and the BSS/MS. The Gb interface is mandatory for the GPRSnetworking.

Physical layer protocol L1

The several physical layer configurations and protocols defined in GSM 08.14are available here. The physical resources shall be configured through theOperation and Maintenance (O&M) process.

FR (NS layer subnet service protocol)

The Frame Relay (FR) sub-layer of the Gb interface belongs to the NS Sub-Network Service protocol. The FR module enables the interworking of sub-network so that the PCU may connect to the SGSN through point-to-pointconnection or the frame relay network. The point-to-point connection refers tothe direct connection between the PCU and SGSN. Generally the PCU acts asthe DTE and the SGSN the DCE. You may flexibly set the network features ofthe PCU and SGSN. Huawei PCU supports the above two connection modes.

The link layer protocol of the Gb interface is based on the FR and defined inthe GSM 08.16. Establish a FR virtual circuit between the SGSN and BSS,which is to be multiplexed by the LLC PDU from multiple subscribers. Thisvirtual circuit may be multi-hop and traverse the network consisting of FRswitching nodes. The frame relay is used for signaling and data transmission.

Load sharing of subscriber data.

One of the most important functions of the NS layer is to perform

load sharing of the subscriber data. When upper layer subscriberstransmit data to the NS layer, the system allocates an LSP for eachsubscriber and encapsulates it to the data packet. The NS layerensures the sequence of subscriber data transmission based on theLSPs. The NS layer selects one or several available NS-VCs totransmit the subscriber data packets based on the LSP and BVCI sothat the load is shared among all unblocked NS-VCs of the sameNSE.

BVCI

This parameter is not part of the BSSGP PDU across the Gb interface, but is

used by the network service entity across the Gb A BVCI needs not to be unique within an SGSN, a BVCI is unique within an

NS Entity. BVCI together with NSEI uniquely identify a BVC within an SGSN(the global identifier within an SGSN is BVCI+NSEI)

Each BVC is identified by means of a BSSGP Virtual Connection Identifier(BVCI) which has end-to-end significance across the Gb interface. EachBVCI is unique between two peer Network Service Entities

peer point-to-point (PTP) functional entities : PTP user data transmission.There is one PTP functional entity per cell. A cell is identified by a BVCIunless it is explicitly stated otherwise

peer point-to-multipoint(PTM) functional entities: PTM user datatransmission. There is one or more PTM functional entities per BSS

peer signalling functional entities : Signaling transmission, such as: PAGINGmessage. Each NSE corresponds a SIG BVC. There is one or more NSEs perBSS

The configuration principles are as follows.

A BSC can be connected to several SGSNs.

A BSC can be configured with several NSEs.

An SGSN can correspond to several NSEs in a BSC, but all the NSVCs and PTPBVCs inone NSE can only serves for one SGSN. In the FR mode, the NSVC ID in the BSC mustbe identical with the NSVC ID in the SGSN.

One cell corresponds to one PTPBVC.

A BSC can be configured with cells that belong to different SGSNs.If the BSC and the

SGSN is connected directly point-to-point, the timeslots on the same E1 cable should be bound as many to one bearer channel.

Principles for Configuring the Links on the Gb Interface

No limit is set on the number of the NSVCs to be configured on one BC. It isrecommended that you do not configure more than two NSVCs serving the same NSEon the same BC so that the NSVCs can be evenly distributed in the system.
