Interworking with HLR data configuration(TDM)

MSC Data Configuration to HLR

I. Chapter1: Relative Concept

Application of MAP in MSC

 

MAP

MAP is mobile application part，MAP protocol is used to help MS to implement roaming and other functions then the mobile network entities can inter-communicate signaling with each other (mobility management). Network entities contain MSC Server, VLR, SGSN, HLR, SMC etc. In UMTS network，C, D, E, G interface can transmit MAP signaling，usually we call these interfaces as MAP interfaces.

MAP Protocol Stack

Explanation

Now, we usually use the C/D interface based on the TDM.

MAP stack between MSC and HLR based on TDM

II. Chapter2: Configuration Procedure

Data Configuration Based on Protocol Stack

The relationship of parameters

Configuration steps

1. Data prepare (negotiated data):  

2. MTP3 layer  data Configuration:

      1) add MTP DPC              ADD N7DSP( HLR is DPC)

      2) add MTP link set          ADD N7LKS( to HLR)

      3) add MTP  route            ADD N7RT  ( to HLR)

        4) add MTP  link                     ADD N7LNK ( to HLR)

3. SCCP data Configuration

The Flow of Location Update

  

General Number Analysis Flow

The type of GT Data

III. Chapter3: Example of Configuration

This example is to add a local HLR, which is directly connected to the MSC through E1 line. （Based on TDM) Physical Connected：

Preparing Data

Configuration Example

Script (MTP data configuration)

ADD N7LKS: LSX=2, ASPX=2, LSNAME="TO HLR";

ADD N7RT: LSX=2, DPX=2, RTNAME="TO HLR";

ADD N7LNK: MN=22, LNKN=2, LNKNAME=“HLR”, LNKTYPE=0, TS=48（ACCORDING PLAN）, LSX=2, SLC=0, SLCS=0;

Script (SCCP SSN data configuration)

ADD SCCPDSP: DPX=2, NI=NAT, DPC="BFF09", DPNAME="HLR", SHAREFLAG=NONE;

ADD SCCPSSN: SSNX=3, NI=NAT, SSN=SCMG, SPC=“BFF09”, OPC=“3000”, SSNNAME=“SCMG-HLR”;（LOCAL TO REMOTE）

ADD SCCPSSN: SSNX=4, NI=NAT, SSN=HLR, SPC="BFF09", OPC="3000", SSNNAME="HLR-HLR"; （LOCAL TO REMOTE）
Script (IMSI GT data configuration)

ADD IMSIGT: MCCMNC=“46009”, CCNDC=“86139”（E.212  to  E.214）;

ADD SCCPGT: GTX=1, GTNAME=“HLR-IMSIGT”, NUMPLAN=ISDNMO（NECESSARY）, ADDR=K'86139, RESULTT=LSPC2, SPC="BFF09";

ADD SCCPGT: GTX=2, GTNAME="HLR-GT", NUMPLAN=ISDN, ADDR=K'8613817550000, RESULTT=LSPC2, SPC="BFF09";

ADD SCCPGT: GTX=3, GTNAME="HLR-MSISDN", NUMPLAN=ISDN, ADDR=K'861390755, RESULTT=LSPC2, SPC="BFF09";

Chapter Summary

This chapter give a whole data configuration to HLR.

Please pay high attention on the preparing data, because some data must be same with remote office.

VI: Chapter4:  Relative Debugging Command

Check MTP Relative Configuration

Check all MTP configuration

Check MTP Relative Information

Display MTP information

Result of Display MTP Relative Information

DSP N7DSP normal status:

“Accessibility = Accessible”

DSP N7RT normal status:

“Route Information =  Healthy

Transfer Allowed           In Service

……”

DSP N7LNK normal status:

“Status = In Use, Healthy,

Not Blocked,

Activated,

……”

MTP Maintenance Command

To manage prohibited MTP link, the link will be unavailable ——INH N7LNK

Release manage prohibited MTP link ， the link will be unavailable ——UIN N7LNK

To activate the MTP link ——ACT N7LNK

To deactivate the MTP link ——DEA N7LNK
