¿µ¹®³»¿ë¿ä¾à This standard defines MMC protocol based on the IP multicast network to provide real-time one-to-many multicast communication over the IP-based (including NGN) fixed and mobile communications network, i.e., MMC-2 protocol. The major functions in the MMC-2 protocol include support for session join, user leave, status monitoring, and handover support. This standard introduces entities of the MMC-2 protocol which includes mobile node, multicast contents server, session manager, and local mobility controller. This standard also defines the reference network configuration which consists of the MMC-2 protocol entities. MMC-2 protocol defines 13 messages that are used to define procedures of for session join, user leave, status monitoring, and handover support for mobile nodes.
The annex provides reference to the various timers used in the MMC-2 protocol and state transition diagram of the MMC-2 protocol entities.
