GSM Bureau data production 3 (Erision)

Chapter 3 add data production for the HLR Board
To add a new HLR Bureau in this province, You need to define the signaling points, Signaling routes, and other data in MSC. You also need to define a GTRC pointing to this HLR. Under normal circumstances, the new HLR board will also have several number segments cut into the Bureau, you can refer to "data production of new number segments".
The following example shows how to create a new Shantou hlr B Bureau.
1. Define signaling points
C7SPI: SP = 2-19-255-128;
C7PNC: SPID = STBGHLR;
2. Define Signaling routes
C7RSI: DEST = 2-19-255-128, PRIO = 1, LS = 2-19-255-17;
C7RSI: DEST = 2-19-255-128, PRIO = 1, LS = 2-19-255-19, LSHB = 1;
The above definition indicates that the signals sent to the Bureau are transferred by Jiangmen TR and Foshan TR in the form of load sharing. The LSHB parameter is the Load Sharing Bit, which indicates which Bit of the SLS code (Signaling Link selection code, composed of four bits) determines the Load balancing.
3. Activate signaling Routing
C7RAI: DEST = 2-19-255-128;
4. Define the SCCP layer signaling points and subsystems
C7NPI: SP = 2-19-255-128;
C7NSI: SP = 2-19-255-128, SSN = 6;
The SSN parameter is the number of the neutron System in the SCCP network. 6 is HLR, 7 represents VLR, 8 is MSC, and 254 is BSC .......
5. Define Monitoring Data
C7RUC: DEST = 2-19-255-128, Alb = A2, DMI = 0;
Activated if necessary
C7RUI: DEST = 2-19-255-128;
6. Define GTRC
C7GCI: GTRC = 73, PSP = 2-19-255-128, PERM;
7. Define the number segment of the HLR board.
Chapter IV data production of the new international roaming Board
The IMSI table, B table, GT table, and D table must be modified in MSC to add data from the International Roaming Bureau.
I. IMSI table modification
MGIZI;
MGICI;
MGISI: IMSIS = 42401, M = 5-97150, NA = 4, ANRES = OBA-30 & BO-72 & MAPVER-0 & NRRG-2 & CBA-28;
MGISI: IMSIS = 42402, M = 5-97150, NA = 4, ANRES = OBA-30 & BO-72 & MAPVER-0 & NRRG-0 & CBA-28;
MGIAI;
In ANRES, the key parameter is CBA-x. That is, the D parameter in Table B should be D = 6-x, And the TDCL value corresponding to D = 6-x in table D should be all CBA values except CBA-x, so as to implement the BOIEXH business (that is, to limit all international outbound calls except to the home country ).
Ii. Modify Table D
ANDSP: D = ALL;
ANDSI: D = 6-0, TDCL = ...; ! TDCL takes all TDCL values (including the 28 values added in this example )!
ANDSI: D = 6-x, TDCL = ...; ! TDCL: All TDCL values except x!
......
ANDSI: D = 6-28, TDCL = 1 & 2 & 22 & 60 & 63;
......
TDCL is determined by instructions on the site. Here is only an example.
3. Modify Table B
ANBZI;
ANBCI;
ANBSI: B = 31-00971, RC = 6, CC = 18, D = 6-28;
ANBSI: B = 58-971, RC = 6, CC = 18, L = 7-15, M = 0-00;
ANBAI;
Iv. Modify the GT table
C7TZI;
C7TCI;
C7GSI: TT = 0, NA = 4, NP = 1, NS = 971, GTRC = gtrc;
C7GSI: TT = 0, NA = 4, NP = 7, NS = 971, GTRC = gtrc;
C7TAI;
The NS here only needs to analyze the international area code of the country. GTRC points to HSTP1 or HSTP2. For details, refer to the first place of NS. If it is an odd number, it points to HSTP1. If it is an even number, it points to HSTP2 to achieve simple load balancing. (Except for NS = 85X, which is determined by the second digit)
