GPRS – Serving GPRS Support Node (SGSN) - Visitors Location Register (VLR); Gs interface network service specification

(P) GSM Rel-98 v7.0.1    1999/07    23 p.
(P) GSM Rel-97 v6.1.0    1999/02    16 p.

Rapporteur:  DAWES, Peter
Descendant(s):  TS 29.016    

This TS specifies or references the subset of MTP and SCCP which is used for the reliable transport of BSSAP+ messages in the Gs interface. This TS also specifies the SCCP addressing capabilities to be provided in the Gs interface.

This TS is divided into two main parts, Chapter 5 dealing with the use of MTP and chapters 6-7 dealing with the use of SCCP.

Clause 5 of this TS deals with the subset of the MTP that is required between an SGSN and a VLR. It is intended that this implementation of MTP is compatible with a full MTP implementation.

The SCCP is used to provide message routing between the SGSN and the VLR. The SCCP routing principles specified in this TS allow to connect one SGSN to several VLR. No segmentation at SCCP level is needed on the Gs interface. Only SCCP class 0 is used on the Gs interface. Clauses 6-7 identify the SCCP subset that should be used between an SGSN and an VLR.
