Method and apparatus for multicast group management

摘要

It provides a method for multicast group management. The apparatus with proxy function maintains a database recording the information relating to the receiver device, so it is capable of carrying out the proxy function based on the database on behalf of the multicast receiver device when the receiver device intends to join/leave a multicast service or respond a query message. As a consequence, it reduces the messages exchanged in unreliable wireless connection so as to reduce the probability of service interruption.
