ETSI TS 129 011

The scope of ETSI TS 129 011 is to provide a detailed specification for interworking between the A interfaceprotocol and the Mobile Application Part for handling of supplementary services. The MAP interfaces of interest are theB-, C-, D- and E-interfaces.

The A-, C-, D- and E-interfaces are physical interfaces while the B-interface is an internal interface defined formodelling purposes. Information relating to the modelling interface is not normative in this specification.

Supplementary service signalling may be passed by the MSC/VLR between the A- and E-interfaces after inter-MSChandover. This procedure is transparent as far as supplementary services are concerned therefore interworkingconcerning this process is not described in this specification.

Clause 2 describes general procedures for interworking between the A- and D- physical interfaces.

Clause 3 describes the general procedures for the SS version negotiation.

Clause 4 describes the mapping of layer 3 radio path messages with Transaction Capabilities (TC) transaction sublayermessages for interworking between the A- and D- physical interfaces.

Clause 5 describes specific interworking procedures for all interfaces relating to call related SS activity.

Clause 6 describes specific interworking procedures for all interfaces relating to call independent SS activity. Clause 6also covers the interworking between the MAP User (see 3GPP TS 29.002) and the SS handling functions of thenetwork entities (see 3GPP TS 24.010 and 3GPP TS 24.080).
