    摘要: A user terminal is registered with a satellite communications system including a plurality of satellite spot beam transmitters; wherein each of the satellite spot beam transmitters defines a respective spot beam. A periodic oscillation of two adjacent satellite spot beam transmitters results in a change of geographic coverage for the respective adjacent spot beams so that the user terminal can be alternatingly covered by the first and second spot beams when the user terminal is stationary. Upon determining that the user terminal is alternatingly covered by the first and second spot beams, the user terminal is registered with a spot beam pair for both the first and second adjacent spot beams and the spot beam pair registration is stored in the user terminal memory. Communications operations between the user terminal and the satellite communications system may be terminated and later re-established, whereupon the user terminal reregisters with the spot beam pair registration stored in memory. Related user terminals are also discussed.

    摘要: A method of processing an incoming call page from a radiotelephone communications system at a mobile user terminal includes receiving the incoming call page from the radiotelephone communications system at the mobile user terminal, and determining a period of time within which the mobile user terminal can respond to the incoming call. An indication of the period of time within which the user terminal can respond to the incoming call is then provided to a user of the mobile user terminal. In addition, the incoming call page can be one of a predetermined number of incoming call pages addressed to the mobile user terminal in a sequence wherein each of the incoming call pages in the sequence includes information identifying the respective incoming call page within the sequence. Accordingly, the step of determining the period of time within which the mobile user terminal can respond to the incoming call can include determining the number of incoming call pages in the sequence to follow.

    摘要: A wireless communications system supports affinity groups of like minded individuals who wish to know locations of other members of the affinity group. The system supports members of the affinity group querying, through a mobile terminal for the location of a remote member of the affinity group as sensed by the remote member's mobile terminal. Rather than report raw geocoordinates, location place-name descriptions are defined by the members of the affinity group and shared amongst one another. Additionally, situational alarms may be generated in the event certain user defined criteria are met, such as two remote members of the affinity group being in close proximity to one another.

    摘要: A multi-mode mobile station receives a subscriber identity module (SIM) card storing at least certain communications standard required subscription information that is common to a plurality of types of cellular telecommunications systems. The mobile station also includes an internal memory for storing communications standard required subscription information unique to each type of cellular telecommunications systems for which mobile station operations are supported. If a certain type of cellular telecommunications system is selected for mobile station operation, and the inserted SIM card fails to include the necessary communications standard required subscription information for that type of system, the common information is extracted from the SIM card and used in combination with the internal memory stored unique information specific to the selected type of system in effectuating mobile station operation.

    摘要: A method of interpreting location area information data in a satellite/terrestrial dual mode mobile terminal is provided, with the mobile terminal in the satellite mode and communicating with a satellite system. The method includes the steps of determining if a most recent registration of the mobile terminal was accomplished in the satellite or terrestrial mode and, if it is determined that the most recent registration of the mobile terminal was accomplished in the terrestrial mode, then determining if (1) a satellite operator ID broadcast by the satellite system matches a satellite operator ID from a most recent satellite location update of the mobile terminal, and (2) a satellite beam pair in a satellite spotbeam pair list broadcast by the satellite system matches a satellite beam pair in a satellite spotbeam ID from a most recent satellite location update of the mobile terminal. If matches are found at both steps (1) and (2) above, then the mobile terminal initiates a location update with the satellite system in the matching satellite beam pair determined at step (2). If matches are not found at either steps (1) and/or (2) above, then the mobile terminal initiates a location update with the satellite system in the satellite spotbeam ID broadcast by the satellite system.

    摘要: A user terminal is operable to acquire service in a satellite mobile communication network in which plural service providers each communicate via satellite with users on one or more spotbeams each having a select frequency. The user terminal comprises a communication system including a transmitter and a receiver for communicating via a spotbeam. A memory stores frequency information. The frequency information identifies carrier frequencies associated with the spotbeams in the network. The memory further stores identification information identifying a service provider associated with each carrier frequency. A communication controller is operatively associated with the communication system and the memory for selecting a spotbeam carrier frequency to communicate on, the communication controller utilizing identification information to select the spotbeam carrier frequency.
