subsystem based on the Session Initiation Protocol (SIP), the Session Description Protocol (SDP), the Binary Floor
Control Protocol (BFCP) and the ControLling mUltiple streams for tElepresence (CLUE) controlling multiple streams
for telepresence based on service requirements.
The present document addresses the areas of describing and negotiating IM session with multiple media streams based on the IM CN subsystem, including point to point calls as specified in TS 24.229
and multiparty conferences as specified in TS 24.147
, to facilitate the support of telepresence.
The functionalities for conference policy control and the signalling between a MRFC and a MRFP are not specified in this document.
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, CLUE and BFCP, either directly, or as modified by TS 24.229
The present document is applicable to Application Servers (ASs), Multimedia Resource Function Controllers (MRFCs), Multimedia Resource Function Processors (MRFP) and User Equipment (UE) providing IM session supporting telepresence capabilities.
