ETSI TS 129 332

ETSI TS 129 332 describes the protocol to be used on the Media Gateway Control Function (MGCF) – IM MediaGateway (IM-MGW) interface. This interface provides the Media Gateway Control for interworking between the IPMultimedia Subsystem (IMS) and CS domain (ISUP, BICC and SIP-I). The basis for this protocol is the H.248 protocolas specified in ITU-T. The IMS architecture is described in 3GPP TS 23.228 [1]. The interaction of the MGCF-IMMGW interface signalling procedures in relation to the SIP, and BICC/ISUP signalling at the MGCF are described in3GPP TS 29.163[4].

The interaction of the MGCF-IM MGW interface signalling procedures in relation to the IMS SIP and SIP-I on Nc atthe MGCF are described in 3GPP TS 29.235[47].

This specification describes the application of H.248 on the Mn interface. Required extensions use the H.248 standardextension mechanism. In addition certain aspects of the base protocol H.248 are not needed for this interface and thusexcluded by this profile.

In addition this profile provides support for PSTN/ISDN Emulation as required by ETSI TISPAN.

The specification contains a normative Annex defining the H.248.1 Profile in accordance with ITU-T recommendationsfor H.248.1 applications. Where there exists any contradiction between the normative Annex A and the rest of thespecification, the Nornative Annex shall take precidence. The main body of the specification provides an introduction tothe use of the profile for the Mn interface and introduces any specific functionality (e.g. new packages) associated to theMn.
