    摘要： Techniques for minimizing call setup latency are disclosed. In one aspect, a channel assignment message is sent with a flag to direct the use of previously negotiated service parameters. This aspect eliminates the need for service negotiation messages. In another aspect, a channel assignment message is sent with an active set identifier instead of an active set and its parameters. This aspect reduces the transmission time of the channel assignment message. In yet another aspect, call setup without paging is facilitated by a mobile station (106) sending a pilot strength measurement message between active communication sessions, such that a channel assignment message can be used for mobile station terminated call setup without the need for mobile station paging and related messages.

    摘要： A method and system for a handoff in a broadcast communication system is disclosed. A subscriber assisted handoff is impractical in a broadcast communication system due to e.g., a high signaling load, a difficulty to synchronize the broadcast transmission. On the other hand, the small number of broadcast channels enables the subscriber station to perform the handoff autonomously. To streamline the autonomous handoff decision process, several distinct sets of pilot identifiers and rules for transitioning among the sets are defined. To fully integrate broadcast services with the services provided by the cellular telephone systems in a subscriber environment, a methods for various handoff scenarios are analyzed.

    摘要： A wireless communications network (100) includes various base stations (110) and subscriber-stations (114). The base stations each provide (602) broadcast content services to subscriber-stations over communication channels of one of the following types: 1) shared channels for use by multiple subscriber-stations, 2) individual channels each dedicated for use by an individual subscriber-station. In response to one or more prescribed condition changes (604), there is a switch (606) in the type of communications channel used to provide broadcast content services to one or more given subscriber-stations.

    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.
