摘要： A method for managing a point-to-point call initiated (702) between a wireless mobile station (114, 400) and a remote party while the mobile is receiving broadcast content via one or more multi-user forward-link broadcast channels (508). The mobile station notifies (704) the network (110) of preferences as to prescribed categories of operating conditions, such as whether to continue receiving the broadcast content, and election between the point-to-point call and the broadcast content should network resources be unable to conduct the point-to-point call and broadcast content concurrently. In accordance with the preferences, communications are conducted (706) in one of the following operating modes: (1) conducting the point-to-point call and discontinuing reception of the broadcast, (2) conducting the point-to-point call and continuing reception of the broadcast, (3) aborting completion of the point-to-point call and continuing reception of the broadcast.

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.
