29、-01)63GPP TS 24.103 version 14.2.0 Release 141 Scope The present document provides the protocol details for telepresence using the IP Multimedia (IM) Core Network (CN) subsystem based on the Session Initiation Protocol (SIP), the Session Description Protocol (SDP), the Binary Floor Control Protocol

30、(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

31、 to point calls as specified in 3GPP TS 24.229 2 and multiparty conferences as specified in 3GPP TS 24.147 3, 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,

32、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 3GPP TS 24.229 2. The present document is applicable to Application Servers (ASs), Multimedia Resource

33、 Function Controllers (MRFCs), Multimedia Resource Function Processors (MRFP) and User Equipment (UE) providing IM session supporting telepresence capabilities. 2 References The following documents contain provisions which, through reference in this text, constitute provisions of the present documen

48、lepresence overview 4.1 General As an architectural framework for provision of IP multimedia services, IMS is capable of delivering various service functionalities and easing to integrate with new kinds of application, such as telepresence. Compared to traditional video conference, telepresence is a

49、 communication system with multiple cameras, microphones and screens that has the characteristics of gaze direction, eye contact, spatial audio and scaling images to true size, which in all to achieve the immersive “being there“ experience for participants. IMS is using the IETF defined session control mechanism with the inherited capability to negotiate multiple multimedia streams in one single session, which could be applied as a basis for supporting telepresence in IMS that always has the necessity of producing and rendering variou
