Downlink multicast method in wireless internet protocol system
First Claim
1. A method for transmitting multicast packet data to a multicast group on a wireless downlink in a wireless system, the wireless system having an access point serving a plurality of wireless terminals, the method comprising the steps of:
- establishing a target member set representing a wireless terminal of the plurality of wireless terminals being served by the access point which is a member of the multicast group;
receiving, by the access point, the multicast packet data; and
determining a destination subset of a target member set representing ones of the plurality of wireless terminals to receive the multicast packet data.

Abstract
A method for determining multicast versus unicast of packet data is a wireless communication system establishes (102) a target member set which represents the wireless terminals (10-14) served by an access point (30-32) which wireless terminals a members of a multicast group. The access point receives (104) the packet data. The access point next determines (106) a destination subset of the target member set of wireless terminals. The destination subset is those wireless terminals which are to receive the packet data.

18. A method for transmitting multicast packet data to a multicast group on a wireless downlink, a wireless system having an access point serving a plurality of wireless terminals, the method comprising the steps of:
-
establishing a target member set representing a wireless terminal of the plurality of wireless terminals served by the access point which is a member of the multicast group;
receiving, by the access point, the multicast packet data;
computing a first cost of multicasting the multicast packet data on the wireless downlink; and
computing a second cost of unicasting a copy of the multicast packet data on the downlink to wireless terminals in a target set. - View Dependent Claims (19, 20)
