ETSI ETSI TR 122 948 V15.0.0 (2018-07)63GPP TR 22.948 version 15.0.0 Release 151 Scope The present document studies the requirements for IP-Multimedia Subsystem (IMS) Convergent Multimedia Conferencing (CMMC) service in IMS. Specifically, the obje
32、ctive of this study item is to: a) Identify features of IMS multimedia conferencing, and describe potential service requirements for IMS multimedia conferencing. b) Identify the IMS requirements for multimedia conferencing services: 1) the conference framework 2) data sharing session establishment/t
33、ermination/management in a conference 3) media control for audio, video and data 4) floor control for audio, video and data 5) conference policy c) Identify possible routes to standardization by: 1) Adopting existing and emerging standards, e.g. OMA, IETF, W3C. 2) Modifying and enhancing existing an
34、d emerging standards. 3) Developing of new standards. 2 References The following documents contain provisions which, through reference in this text, constitute provisions of the present document.

42、ms and definitions given in TR 21.905 1 and the following apply. CMMC Service Subscriber: A subscriber that has been provisioned with a CMMC service. Conference: An IP multimedia session with two or more participants. Each conference has a “conference focus”. A conference can be uniquely identified
43、by a user. An example for a conference could be a multimedia game, in which the conference focus is located in a game server. Conference Focus: The conference focus is an entity which has abilities to host conferences including their creation, maintenance, and manipulation of the media. A conference
44、 focus implements the conference policy (e.g. rules for talk burst control, assign priorities and participants rights). Note: Definition of Conference Focus taken from TS 22.228 2 and is not in conflict with the IETF definition in RFC4353 5. Floor: An individual temporary access or manipulation perm
45、ission for a specific shared resource (or group of resources) RFC 4376 4. Floor Chair: A floor chair is a human or automated entity, who is authorized to manage access to one floor and can grant, deny or revoke access. The floor chair does not have to be a participant in the conference instance. Flo
46、or Control: Floor control is a means to manage joint or exclusive access to shared resources in a conferencing environment RFC 4376 4. Floor Owner: Floor owner is a conference participant who is granted the floor and is allowed to send media. Host: The conference host is a specific conference partic
47、ipant who manages and controls the conference, e.g. adding and removing participants, adding and removing media in the conference, terminating the conference etc. There is only one host in a conference. 3.2 Abbreviations For the purposes of the present document, the following abbreviations apply in
