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.

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.

Method and apparatus for enhanced selection of a channel for use in redistributing mobile stations to various frequencies in a communication system. In one aspect, the method appends a redistribution alteration record to a common channel redistribution message. The redistribution alteration record alters the sequencing of the mobile station when selecting a channel in the common channel redistribution message.

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 method 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 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.
摘要:
A method and a system for providing signaling in cellular telephone system providing broadcast services to fully integrate broadcast services with the services provided by the cellular telephone systems. The signaling method coordinate interaction between an access network and the subscriber station to allowing the subscriber station to decode the broadcast service, to receive paging messages while receiving the broadcast service, to properly transition between operation states, and other functions known to one of ordinary skill in the art.

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 and system are provided that allow a mobile communications service provider to broadcast messages using more than one broadcast channel protocol, such that only the mobile stations designed to receive broadcast messages transmitted under each protocol are woken up to monitor their respective broadcast channel slots, thus saving battery life in mobile stations designed to receive broadcast messages transmitted using other broadcast channel protocols.
