Mobility management of multiple clusters within a wireless communications network
First Claim
1. A method of instructing access terminals with regard to how to handle a cluster collision in a wireless communication system, comprising:
- determining whether first and second clusters within the wireless communication system overlap at least partially with each other, the first cluster including a first plurality of sectors and the second cluster including a second plurality of sectors, the first cluster carrying a given multicast session on a first interlace-multiplex (IM) pair of a downlink broadcast channel within each of the first plurality of sectors and the second cluster carrying the given multicast session on a second IM pair of the downlink broadcast channel within each of the second plurality of clusters; and
controlling a manner in which the first and second clusters carry the given multicast session based on the determining step.

Abstract
Aspects of mobility management within a wireless communications network including a plurality of sectors are disclosed. In an example, the wireless communications network includes a first cluster of sectors with at least one target sector and at least one supporting sector. The multicast communication session is carried within both the target and supporting sectors. In another example, a second cluster can be included within the network for supporting the same multicast communication session that includes its own target and supporting sectors. In this example, the first cluster transmits multicast media on a first interlace-multiplex (IM) pair of a downlink broadcast channel (BCH) and the second cluster transmits multicast media on a second IM pair of the downlink BCH. If sectors of the first and second clusters overlap, the network controls a manner in which the first and second clusters carry the multicast media.
