ETSI ETSI TS 183 031 V2.0.0 (2008-02) 5 1 Scope The present document provides the necessary extensions and modifications to 3GPP TS 29.333 1 required for use in a TISPAN NGN. 3GPP TS 29.333 1 describes

15、 the protocol to be used on the Multimedia Resource Function Controller (MRFC) - Multimedia Resource Function Processor (MRFP) interface (Mp interface). This specification defines a profile of the Gateway Control Protocol (H.248.1), for controlling Multimedia Resource Function Processor supporting i

16、n-band user interaction, conferencing and transcoding for multimedia-services. 2 References References are either specific (identified by date of publication and/or edition number or version number) or non-specific. For a specific reference, subsequent revisions do not apply. Non-specific reference

17、may be made only to a complete document or a part thereof and only in the following cases: - if it is accepted that it will be possible to use all future changes of the referenced document for the purposes of the referring document; - for informative references. Referenced documents which are not fo
