    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： Method and a system for multicast service notification in cellular telephone system to enable the cellular telephone systems to provide both multicast and point-to-point services are disclosed. Several embodiments describe the signaling interaction between an access network and subscriber stations belonging to a multicast group to allow the access network to properly notify the subscriber stations of a the multicast service. Such a signaling further allows the subscriber stations to recognize the multicast service notification to participate in the multicast service.

    摘要： During initiation procedure between subscriber stations and access network adhering to CDMA standards, (e.g., IS-95 and IS-2000) the subscriber station receives a Sync Channel Message. Due to a design/manufacturing error, certain subscriber stations adhering to the IS-95 fail to ignore a portion of the Sync Channel Message, intended for a proper operation of subscriber stations adhering to the IS-2000. This causes a failure of the IS-95 subscriber stations' operation. The disclosed invention describes embodiments allowing the faulty subscriber stations to operate on an access networks build in accordance with both IS-95 and IS-2000 standards.

    摘要： Techniques for synchronization of stored service parameters are disclosed. In one aspect, a configuration identifier is transmitted from a mobile station to a base station, and compared with an identifier generated in the base station. If the identifiers match, the configuration is used for communication. In another aspect, the identifier is generated by selecting an identifier associated with a configuration from a configuration table. In yet another aspect, the identifier is generated by computing a cyclic redundancy check (CRC) of the configuration. Various other aspects are also presented. These aspects have the benefit of preventing attempted use of unsynchronized stored service parameters and associated call setup failures and subsequent renegotiation, with the net effect of reducing call setup time and more efficient use of system resources.

    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 able 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.
