20100048206 | METHOD AND APPARATUS FOR BROADCAST SERVICES IN A COMMUNICATION SYSTEM - A method, apparatus and system provide for efficient use of communication resources for providing broadcast services in a communication system. A receiver receives a first broadcast controller identification from a first base station, and a second broadcast controller identification from a second base station. A controller coupled to the receiver determines whether the first and second broadcast controller identifications are associated with use of a common set of broadcast parameters. A transmitter transmits a request for transmission of a new set of broadcast parameters when the first and second broadcast controller identifications are not associated with use of the common set of broadcast parameters. After receiving the new set of broadcast parameters, the receiver uses the new set of broadcast parameters for receiving broadcast services. | 02-25-2010 |
