Allocating interlace multiplex pairs for multicast services
First Claim
1. A method implemented in a control entity within a wireless communication system, comprising:
- selecting, at the control entity, a plurality of sectors in response to receiving requests for a multicast service from mobile units located within the plurality of sectors;
allocating, at the control entity, at least one of a plurality of interlace-multiplex pairs for providing the multicast service to the mobile units within the plurality of sectors, wherein said at least one interlace-multiplex pair is allocated based on at least one priority list that ranks priorities of the plurality of interlace-multiplex pairs according to how many of the plurality of sectors provide the multicast service using the corresponding interlace-multiplex pair; and
establishing a call flow over an air interface to the mobile units using said at least one allocated interlace-multiplex pair.

Abstract
The present invention provides a method implemented in a control entity within a wireless communication system. The method includes selecting, at the control entity, a plurality of sectors in response to receiving requests for a multicast service from mobile units located within the plurality of sectors. The method also includes allocating, at the control entity, one or more interlace-multiplex pairs for providing the multicast service to the mobile units within the plurality of sectors. One or more of the interlace-multiplex pairs are allocated based on a priority list that ranks priorities of the plurality of interlace-multiplex pairs according to how many of the plurality of sectors provide the multicast service using the corresponding interlace-multiplex pair. The method also includes establishing a call flow over an air interface to the mobile units using the allocated interlace-multiplex pair(s).

7. A method implemented in a control entity within a wireless communication system, comprising:
-
selecting, at the control entity, a plurality of sectors in response to receiving requests for a multicast service from mobile units located within the plurality of sectors, wherein selecting the plurality of sectors comprises selecting a plurality of sectors that comprises at least one target sector that includes at least one of the mobile units and at least one support sector for said at least one target sector; selecting said at least one support sector using a neighbor list for said at least one target sector; allocating, at the control entity, at least one of a plurality of interlace-multiplex pairs for providing the multicast service to the mobile units within the plurality of sectors, wherein said at least one interlace-multiplex pair is allocated based on at least one priority list that ranks priorities of the plurality of interlace-multiplex pairs according to how many of the plurality of sectors provide the multicast service using the corresponding interlace-multiplex pair, wherein allocating said at least one interlace-multiplex pair comprises; allocating an available interlace-multiplex pair to a first one of the plurality of sectors before assigning any other interlace-multiplex pairs to any other sectors for the multicast service; updating said at least one priority list in response to allocating the available interlace-multiplex pair to the first one of the plurality of sectors; and allocating one of the plurality of interlace-multiplex pairs to at least a second one of the plurality of sectors based upon said at least one updated priority list; and establishing a call flow over an air interface to the mobile units using said at least one allocated interlace-multiplex pair. - View Dependent Claims (8, 9)

10. A method implemented in a control entity within a wireless communication system, comprising:
-
forming, at the control entity, at least one priority list, wherein forming said at least one priority list comprises; forming a first priority list that ranks a plurality of interlace-multiplex pairs according to how many sectors have been allocated a corresponding interlace-multiplex pair; and forming at least one second priority list associated with at least one radio network controller, wherein said at least one second priority list ranks the plurality of interlace-multiplex pairs according to how many sectors associated with the radio network controller have been allocated a corresponding interlace-multiplex pair; selecting, at the control entity, a plurality of sectors in response to receiving requests for a multicast service from mobile units located within the plurality of sectors; allocating, at the control entity, at least one of a plurality of interlace-multiplex pairs for providing the multicast service to the mobile units within the plurality of sectors, wherein said at least one interlace-multiplex pair is allocated based on at least one of the first priority list or the second priority list that ranks priorities of the plurality of interlace-multiplex pairs according to how many of the plurality of sectors provide the multicast service using the corresponding interlace-multiplex pair; and establishing a call flow over an air interface to the mobile units using said at least one allocated interlace-multiplex pair.
