SSH ETS 300 529:1996 ed.3

Digital cellular telecommunications system (Phase 2) (GSM); Technical realization of supplementary services (GSM 03.11)

Scope

This European Telecommunication Standard (ETS) describes the general aspects on how supplementary services in the GSM system are realized from a technical point of view. Description of technical realization for specific supplementary services can be found in GSM 03.8x and 03.9x-series technical specifications. All supplementary services may require signalling on the radio path. Signalling procedures and messages used are defined in the GSM 04.8x and 04.9x-series of technical specifications. For some supplementary services information needs to be transferred between the home location register (HLR), the visitor location register (VLR) and the mobile services switching centre (MSC). Signalling procedures for such information transfer are defined in GSM 09.02.
