Abstract

A method and apparatus for negotiating capability information for a broadcast service in a communication system. In one embodiment, the generic capabilities are pre-configured in BSC, which provides the generic capability information to MS and to PDSN based on a listing of available BC services and the corresponding capabilities. Another embodiment pre-configures PDSN with the generic capability information. According to still another embodiment, PDSN is pre-configured with the generic capability information, wherein the MS queries the PDSN directly for generic capability information via a PPP connection. In yet another embodiment, the MS queries the PCF, which in turn queries all of the PDSN in the system. The PDSN responsible for the BC responds to the query. Where multiple PDSNs may support the BC, the first to respond using multicast addressing obviates the need for the others to respond.

Claims

1. In a communication system supporting broadcast services, a method comprising:

pre-configuring a first infrastructure element with capability information for a first broadcast service;

in response to a request for the first broadcast service, the first infrastructure element providing the capability information to a mobile station.

2. The method as in claim 1, wherein the capability information comprises header compression information and the mapping between BCMCS_ID and IP multicast address.

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

re-configuring the first infrastructure element to update the capability information.

4. The method as in claim 1, wherein the first infrastructure element providing the capability information further comprises:

providing the capability information to a second infrastructure element.

5. The method as in claim 1, wherein the first infrastructure element is a base station controller.

6. The method as in claim 5, wherein the second infrastructure element is a packet data service node.

7. The method as in claim 1, wherein pre-configuring the first infrastructure element comprises establishing access to the capability information for a first broadcast service from a configuration database.

8. The method as in claim 7, wherein pre-configuring the first infrastructure element comprises establishing access to capability information for other broadcast services from the configuration database.

19. The method as in claim 1, wherein the first infrastructure element providing the capability information further comprises:

providing the capability information to a second infrastructure element.

9. An apparatus in a communication system, the communication system supporting broadcast services, the apparatus comprising:
