ETSI ETSI TS 124 247 V15.0.0 (2018-06)63GPP TS 24.247 version 15.0.0 Release 151 Scope The present document provides the protocol details for the messaging service within the IP Multimedia CN Subsystem (IMS) based on the Session Initi
33、ation Protocol (SIP), the Session Description Protocol (SDP) and, the Message Session Relay Protocol (MSRP) . The document covers immediate messaging, session based messaging and session-based messaging conferences, as described in 3GPP TS 22.340 11. Where possible the present document specifies the
34、 requirements for this protocol by reference to specifications produced by the IETF within the scope of SIP, SDP and, MSRP, either directly, or as modified by 3GPP TS 24.229 5. The present document is applicable to Application Servers (ASs) , Media Resource Function Controllers (MRFCs), Media Resour
35、ce Function Processors (MRFPs) and to User Equipment (UE) providing messaging capabilities. This document does not cover the signalling between a MRFC and a MRFP. 2 References The following documents contain provisions which, through reference in this text, constitute provisions of the present docum

49、y and terminate media sessions using the Session Initiation Protocol, as defined in RFC 3261 7. Although these basic mechanisms already allow the exchange of instant messaging information using SIP, this functionality can be extended to provide a richer service within the IMS. The messaging service within the IM CN subsystem provides the means for a user to send or receive single messages immediately to / from another user and to create and participate in a messaging conference with one ore more other users.
