Content for TS 29.333 Word version: 17.0.0

1 Scope p. 8

The present document describes the protocol to be used on the Multimedia Resource Function Controller (MRFC) - Multimedia Resource Function Processor (MRFP) interface (Mp interface). The IMS architecture is described in TS 23.228, the functional requirements are described in 3G TS 23.333

This specification defines a profile of the Gateway Control Protocol (H.248.1), for controlling Multimedia Resource Function Processor supporting in-band user interaction, conferencing and transcoding for multimedia-services.

The present document is valid for a 3rd generation PLMN (UMTS) complying with Release 7 and later.
