This TR studies the requirements for IP-Multimedia Subsystem (IMS) Convergent Multimedia Conferencing (CMMC) service in IMS. Specifically, the objective of this study item is to:
  • Identify features of IMS multimedia conferencing, and describe potential service requirements for IMS multimedia conferencing.
  • Identify the IMS requirements for multimedia conferencing services:
    • the conference framework
    • data sharing session establishment/termination/management in a conference
    • media control for audio, video and data
    • floor control for audio, video and data
    • conference policy
  • Identify possible routes to standardization by:
    • Adopting existing and emerging standards, e.g. OMA, IETF, W3C.
    • Modifying and enhancing existing and emerging standards.
    • Developing of new standards.
