Abstract

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.

Claims

1. A method for providing broadcast services, comprising:

receiving a first identification from a first base station;

receiving a second identification from a second base station;

determining whether the first and second identifications are associated with use of a common set of broadcast parameters; and

requesting transmission of a new set of broadcast parameters from the second base station if the first and second identifications are not associated with use of the common set of broadcast parameters.

2. The method as recited in claim 1, further comprising:

continuing to use the common set of broadcast parameters if the first and second identifications are associated with use of the common set of broadcast parameters.

3. The method as recited in claim 1, further comprising:

receiving said new set of broadcast parameters.

4. The method as recited in claim 3, further comprising:

using said new set of broadcast parameters for receiving broadcast services.

5. An apparatus for providing broadcast services, comprising:

a receiver for receiving a first identification from a first base station, and for receiving a second identification from a second base station;

a controller for determining whether the first and second identifications are associated with use of a common set of broadcast parameters;

a transmitter for requesting transmission of a new set of broadcast parameters from the second base station if the first and second identifications are not associated with use of the common set of broadcast parameters.

6. The apparatus as recited in claim 5, wherein said receiver continues to use the common set of broadcast parameters;

if the first and second identifications are associated with use of the common set of broadcast parameters.

7. The apparatus as recited in claim 6, wherein said controller and receiver are further for using said new set of broadcast parameters for receiving broadcast services.

8. An apparatus for providing broadcast services, comprising:

means for receiving a first identification from a first base station;

means for receiving a second identification from a second base station;

means for determining whether the first and second identifications are associated with use of a common set of broadcast parameters; and

means for requesting transmission of a new set of broadcast parameters from the second base station if the first and second broadcast controller identifications are not associated with use of the common set of broadcast parameters.

9. The apparatus as recited in claim 8, further comprising:

means for continuing to use the common set of broadcast parameters if the first and second identifications are associated with use of the common set of broadcast parameters.

10. The apparatus as recited in claim 8, further comprising:

means for receiving said new set of broadcast parameters.

11. The apparatus as recited in claim 10, further comprising:

means for using said new set of broadcast parameters for receiving broadcast services.

12. A processor-readable medium including processor-executable instructions encoded thereon for performing a method for providing broadcast services, the method comprising:

receiving a first identification from a first base station;

receiving a second identification from a second base station;

determining whether the first and second identifications are associated with use of a common set of broadcast parameters; and

requesting transmission of a new set of broadcast parameters from the second base station if the first and second broadcast controller identifications are not associated with use of the common set of broadcast parameters.

13. The processor-readable medium as recited in claim 12, wherein the method further comprises:

continuing to use the common set of broadcast parameters if the first and second identifications are associated with use of the common set of broadcast parameters.

14. The processor-readable medium as recited in claim 12, wherein the method further comprises:

receiving said new set of broadcast parameters.

15. The processor-readable medium as recited in claim 14, wherein the method further comprises:

using said new set of broadcast parameters for receiving broadcast services.

16. A mobile station, comprising:

a receiver for receiving a first identification from a first base station, and for receiving a second identification from a second base station;

a controller for determining whether the first and second identifications are associated with use of a common set of broadcast parameters;

a transmitter for requesting transmission of a new set of broadcast parameters from the second base station if the first and second identifications are not associated with use of the common set of broadcast parameters; and

an antenna coupled to the receiver to receive the first and second identifications, the antenna further coupled to the transmitter to request the transmission of the new set of broadcast parameters.
