Detailed Description

The Generic Subscriber Update Protocol (GSUP) is an Osmocom-specific non-standard protocol replacing MAP as the protocol between MSC/VLR/SGSN and HLR in a 3GPP cellular communications network.

This header defines SMS (Short Message Service) extensions for Osmocom GSUP (Generic Subscriber Update Protocol).

It was designed around the same transactions and architecture as the MAP messages/operations, but without the complexity of TCAP and MAP, and without the need for ASN.1 encoding.

The purpose is to keep protocol complexity out of OsmoSGSN and OsmoMSC, while providing a clean path to an external GSUP to MAP translator.

The scope of this module is defined by 3GPP TS 29.002, section 12.
