This document describes the protocol to be used on the IBCF–TrGW and the CS-IBCF – CS-TrGW Ix interface. The basis for this protocol is the H.248 protocol as specified in ITU-T. The Profile provides MG control function for IMS and CS Border Control.

The IMS architecture is described in TS 23.228. The underlying reference model and stage 2 information is described in Annex I of TS 23.228 and in TS 29.162. The CS architecture is described in Annex A of TS 29.235.

This specification describes the application of H.248 Ix profile for both Ix and CS-Ix interfaces. Required extensions use the H.248 standard extension mechanism. In addition certain aspects of the base protocol H.248 are not needed for this interface and thus excluded by this profile.
