32、of substance, i.e. technical enhancements, corrections, updates, etc. z the third digit is incremented when editorial only changes have been incorporated in the document. ETSI ETSI TS 129 238 V14.1.0 (2017-03)73GPP TS 29.238 version 14.1.0 Release 141 Scope The present document describes the protoco
33、l to be used on the Interconnection Border Control Function (IBCF) Transition Gateway (TrGW) interface and the CS-IBCF CS-TrGW 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 architect
34、ure is described in 3GPP TS 23.228 2. The underlying reference model and stage 2 information is described in Annex I of 3GPP TS 23.228 2 and in 3GPP TS 29.162 18. The CS architecture is described in Annex A of 3GPP TS 29.235 17. This specification describes the application of H.248 Ix profile for bo
35、th Ix and CS-Ix interfaces (see Figure 1.1 and Figure 1.2). 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. DNS P-CSCF IP-CAN UE S-CSCF I-CSCF TrGW Signalling B
