Abstract
A method and apparatus for providing coverage control for multicast service in a wireless network. The present invention comprises a central transceiver for receiving a membership report from a plurality of wireless communication devices, the membership report identifying a multicast group to which at least one wireless communication device belongs. The central transceiver transmits an indication of the multicast group identified in the membership report to at least a portion of the plurality of wireless communication devices. The wireless communication devices use the information contained within the indication to determine whether or not to transmit a membership report identifying a multicast group to which it currently belongs.
Claims26
An apparatus for providing coverage control for multicast service in a wireless network, said wireless network comprising a central transceiver and a plurality of wireless communication devices, said apparatus comprising:
- said central transceiver comprising:
- a receiver for receiving a membership report from a wireless communication device, said membership report identifying a multicast group, said membership report provided to a processor;
- said processor for generating an indication of said multicast group identified in said membership report;
- and
- a transmitter for transmitting said indication to at least a portion of said plurality of wireless communication devices.
A method for providing coverage control for multicast service in a wireless network, said wireless network comprising a central transceiver and a plurality of wireless communication devices, the method comprising the steps of:
- receiving a membership report from a first wireless communication device, said membership report identifying a multicast group;
- generating an indication of said received membership report by a processor associated with said central transceiver;
- and
- transmitting said indication to at least a portion of said plurality of wireless communication devices, said indication identifying said multicast group identified in said received membership report.
An apparatus for providing coverage control for multicast service in a wireless network, said wireless network comprising a central transceiver and a plurality of wireless communication devices, said apparatus comprising:
- a wireless communication device comprising:
- a processor for generating a membership report identifying at least one multicast group upon the occurrence of a predefined event;
- a receiver for receiving an indication of a membership report transmitted by said central transceiver, said indication identifying at least one multicast group to which a second wireless communication device belongs;
- and
- a transmitter for transmitting said membership report to said central transceiver.
A method for providing coverage control for multicast service in a wireless network, said wireless network comprising a central transceiver and a plurality of wireless communication devices, the method comprising the steps of:
- receiving an indication of a membership report transmitted by said central transceiver, said indication identifying a multicast group to which a second wireless communication device belongs;
- determining whether said multicast group identified in said indication matches a multicast group to which said wireless communication device currently belongs;
- generating a second member report identifying a multicast group to which said wireless communication device currently belongs;
- and
- transmitting said second membership report upon the occurrence of a predefined event if said multicast group identified in said indication does not match said multicast group to which said wireless communication device currently belongs.
A system for providing coverage control for multicast service in a wireless network, said wireless network comprising a central transceiver and a plurality of wireless communication devices, said system comprising:
- said central transmitter for receiving a membership report, said membership report identifying a multicast group that a wireless communication device currently belongs, said central transmitter further for transmitting an indication of said membership report to said plurality of wireless communication devices upon a predetermined event, said indication identifying said received multicast group;
- and
- a second wireless communication device for receiving said indication of membership report and for generating a second membership report if said indication does not identify a multicast group that said second wireless communication device currently belongs.
