EFFICIENT MULTICAST CALL SET UP METHOD AND SYSTEM

摘要

A system (100) and method (200) of setting up a multicast session in a wireless system having at least one access point serving a plurality of wireless terminals that are members of a multicast group can include collecting (202) a member set representing members of the multicast group and receiving (206) a multicast packet by the access point. The method further determines (208) a target set of terminals receiving the multicast packet. If a number of terminals in the target set is greater or equal to a threshold, then the multicast packet is multicast (214) to a multicast address. If the number of terminals in the target set is less than the threshold and greater than zero, then a copy of the multicast packet is unicast (216) to the unicast address of each terminal.
