First Claim
1. A method of multicast management within a wireless communications network including a plurality of sectors, comprising:
- forming a target sector group, the target sector group including at least one target sector from among the plurality of sectors, each target sector expected to have one or more access terminals belonging to a given multicast group;
forming a supporting sector group, the supporting sector group including at least one supporting sector from among the plurality of sectors, each supporting sector not being a target sector and satisfying a proximity metric with respect to at least one target sector; and
transmitting multicast messages associated with the given multicast group in the at least one target sector and the at least one supporting sector.

Abstract
Methods of providing multicast communications within a wireless communications network are provided. In an example, an access network forms a target sector group, the target sector group including at least one target sector from among a plurality of sectors, each target sector expected to have one or more access terminals belonging to a given multicast group. The access network also forms a supporting sector group, the supporting sector group including at least one supporting sector from among the plurality of sectors, each supporting sector not being a target sector and satisfying a proximity metric (e.g., being adjacent to one or more target sectors) with respect to at least one target sector. The access network transmits multicast messages associated with the given multicast group in the at least one target sector and the at least one supporting sector.

22. A method of multicasting in a wireless communications network including a plurality of sectors, comprising:
-
transmitting, at each target sector within a target sector group, a first scheduling message configured to suppress registration feedback from one or more access terminals, the target sectors within the target sector group expected to have one or more access terminals belonging to a given multicast group; periodically transmitting, at each target sector within the target sector group, a second scheduling message in place of the first scheduling message, the second scheduling message configured to prompt registration feedback from one or more access terminals; and first determining, at each target sector, whether to remain a target sector based on whether registration feedback is received in response to one of the periodically transmitted second scheduling messages. - View Dependent Claims (23, 24, 25, 26, 27, 28, 29, 30)
