Network node Configuration Parameters
To configure each mobile network node type, you need the parameters below:
| Parameter name | Description | Applies to | Values or example | Notes |
|---|---|---|---|---|
| PC Type | Type of the SS7 Point Codes | Entire network | ITU, ANSI | |
| NI | Network Indicator | Entire network | national, reserverdnational, international | |
| PC | SS7 Point Code | Each SS7 node | 1035, 1-107-5 | |
| GT | SCCP Global Title | MSC, VLR, SGSN, HLR | 882500010 | May be shared by all components running on a SS7 node |
| MGT Type | Type of GT used for IMSI addressing | Entire network | E.212, E.214 | |
| CC | Country Code prefix | Usually entire network | 882 | VPLMN components located abroad should have local CC |
| Node number | Identity in a cluster | VLR, SGSN | 1 to 10 bits integer | Can be same for VLR and SGSN if a 1:1 relationship exists |
| Node bits | Bits for identity | VLR, SGSN, YateBTS | 1 to 10 | Can be same for VLR and SGSN if a 1:1 relationship exists |
| IGWMSC | Outbound calls gateway | MSC | Protocol specific | Typically the GMSC is also IGWMSC |
| Roaming No | Pool of Roaming Numbers | VLR | 882990020-882990049 | The pool can be shared with handover numbers |
| Handover No | Pool of Handover Numbers | MSC | 882990050-882990059 | The pool can be shared with roaming numbers |
| SGSN GTP-C | GSN IP Address | SGSN | IP Address | Alternative (or only) IPv6 address may be present |
| SGSN GTP-U | GSN IP Address | SGSN | IP Address | May be same or different from the GTP-U Address |
