ETSI ETSI TS 124 247 V14.0.0 (2017-03)63GPP TS 24.247 version 14.0.0 Release 141 Scope The present document provides the

31、protocol details for the messaging service within the IP Multimedia CN Subsystem (IMS) based on the Session Initiation Protocol (SIP), the Session Description Protocol (SDP) and, the Message Session Relay Protocol (MSRP) . The document covers immediate messaging, session based messaging and session-

32、based messaging conferences, as described in 3GPP TS 22.340 11. Where possible the present document specifies the 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 presen

33、t document is applicable to Application Servers (ASs) , Media Resource Function Controllers (MRFCs), Media Resource 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 followi

47、IP Multimedia core network Subsystem (IMS), as defined in 3GPP TS 24.229 5, allow a user to initiate, modify 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

48、 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 o

49、re more other users. Participants to such message based communication may be internal or external to the home network. When to use an immediate message and when to use a session-based messaging session will depend on the application. NOTE: Some participants may always use session-based messaging, while others may use immediate messaging or a combination of session-based messaging and immediate messaging dependant of the characteristics of the messaging session. The criteria are implementation and application s
