摘要： 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.

摘要： A wireless communications network includes roving subscriber-stations and base stations receiving broadcast programs from a content server. A subscriber-station evaluates whether a desired program is available from a subject base station. According to this evaluation, the subscriber-station takes steps to (1) receive the desired program on a shared channel for reception by multiple subscriber-stations, or (2) initiate base station delivery of the desired program to the subscriber-station on an individual channel. Responsive to a message from a subject subscriber-station identifying a desired program, a base station either (1) continues transmitting the desired program upon a shared channel, (2) starts transmitting the desired program on a shared channel, or (3) sends the subject subscriber-station a channel assignment message and commences transmission of the desired program on the assigned individual channel.

摘要： A wireless communications network (100) includes roving subscriber-stations (114) and base stations (110) receiving broadcast programs from a content server. A subscriber-station evaluates (618, 620) whether a desired program is available from a subject base station. According to this evaluation, the subscriber-station takes steps to (1) receive the desired program on a shared channel for reception by multiple subscriber-stations (816), or (2) initiate (804, 720) base station delivery (724) of the desired program to the subscriber-station on an individual channel. Responsive to a message from a subject subscriber-station identifying a desired program, a base station either (1) continues (819) transmitting the desired program upon a shared channel, (2) starts (816) transmitting the desired program on a shared channel, or (3) sends the subject subscriber-station a channel assignment message and commences transmission (722) of the desired program on the assigned individual channel.
