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.
