摘要： Disclosed is a method for applying different charge rates and indicating the location of a mobile station in a cellular mobile telecommunication system. Location information for the major service zone of the mobile station is monitored in the home-zone list to apply different charge rate to the mobile station in the home zone and the non-home zone. By applying the different charge rates according to the location of the mobile station, it is possible to provide a low-priced charge system in which the charge rate is lower than that of the mobile telecommunication network or equal to or slightly higher than that of the PSTN. Moreover, the mobile station indicates its present location by a specific message or a specific tone, so that the subscriber knows both the present location and the type of the charge rate that is currently applied.

摘要： A satellite communications system provides a communications service to a mobile terminal on which different communications applications may be run. Calls are set up between any of the applications via a satellite to a network management centre which provides different service adaptors which adapt the calls to different types of service provided over terrestrial networks, such as telephony, facsimile, internet or ATM services. The bandwidth allocated to each call over the satellite link may be varied during the call according to demand either from the relevant application or from the network management centre. Multiple calls may be connected concurrently to or from different applications running on the mobile terminal. A maximum bandwidth is allocated to each call. Efficient use is thereby made of the limited bandwidth available over the satellite, according to the instantaneous bandwidth requirements of different applications. For real-time calls requiring multiple slots per frame in a TDMA channel, the slots are mutually spaced apart to reduce delay.

摘要： A method for determining the position of a mobile radio telephone in a satellite communication system includes a mobile radio telephone scanning a plurality of paging channels and measuring the signal strength of the paging channels. The mobile radio telephone then selects the paging channel with the strongest signal strength and decodes the information broadcasted on the selected channel. The information contained in the paging channel can include frequencies or timeslots of paging channels in surrounding spot beams. The mobile station then measures the signal strength of paging channels in surrounding spot beams and quantizes the measurements to determine a coarse position of the mobile radio telephone.

摘要： Methods for switching a mobile between operation in an mobile satellite system mode and a terrestrial wireless mode. When operating in the terrestrial wireless mode, the mobile terminal will initiate an attempt to switch into the MSS mode when it nears the boundary of the coverage area for a terrestrial wireless system to which it is registered. Conversely, a mobile terminal operating in the MSS mode will regularly attempt to switch into the terrestrial wireless mode. For both, a switch between modes is contingent on the mobile terminal identifying a suitable system for registration therewith upon completing the switch between modes. The criteria for identifying a suitable system for selection purposes include the following: (1) the selected system is available, i.e., the mobile terminal is physically located within a coverage area for the selected system; (2) the mobile terminal is compatible with the selected system; and (3) the selected system is willing to accept the mobile terminal. If multiple systems meet these criteria, the mobile terminal will utilize a stored list of preferred systems to select therefrom. When switching into the terrestrial wireless mode, the MSS system provides the mobile terminal with switch-over information for the underlying terrestrial wireless systems and, when switching into the MSS mode, the terrestrial wireless system provides the mobile terminal with switch-over information for the overlying MSS systems.

摘要： A mobile satellite communications system having at least one mobile terminal (2), at least one ground station (6), at least one relay satellite (4) interconnecting said user terminal (2) and said ground station (6), and a management store (48) associated with said ground station (6), in which the user terminal (2) is configured to initiate registration signalling with said store (48). The user terminal (2) initiates registration signalling when reception conditions relating to a downlink channel relayed via said satellite (4) become unsatisfactory over a given time greater than a predetermined minimum value and then return to a satisfactory condition. Specifically, signals received in a given channel are monitored in relation to predetermined criteria, and the duration of periods when the monitored signals do not meet the criteria are timed. Signals for updating the location of the user terminal registered in the management store, are transmitted when said monitored signals in said channel again meet said criteria, only if the timed duration for which the monitored signals do not meet the criteria, is not less than a predetermined time (T2).

摘要： An SCR (Selective Call Receiver) (16) that operates in a satellite communication system automatically initiates a re-registration procedure when it roams from one message delivery area (10) to another message delivery area (12). This is accomplished by the SCR (16) determining its present location, determining the distance which it may have roamed from a known previous location and, if that distance exceeds a given distance, initiating the re-registration procedure.

摘要： A method and apparatus for a communication system (100) to register groups of co-located users in a mobile vehicle (110) involves collecting (200) registration information for multiple users by a Vehicle Communications Control Unit (500) (VCCU) on board the mobile vehicle (110), creating (202) at least one group registration request message by the VCCU (500), and sending the at least one group registration request message to an Earth Terminal (102) (ET) of the communication system (100). After the communication system (100) registers each user whose registration information is contained within the at least one group registration request message, the ET (102) sends (312) at least one group registration response message to the VCCU (500), where the message includes information describing whether each registration attempt was successful. The VCCU (500) can then inform (210) each user as to the status of the registration attempt.

摘要： A method and apparatus used by a communication system (100) to optimize the re-registration of communication system users that use a variable speed multiple-user communication unit (VSMCU) (110). VSMCUs (110) can be located on mobile vehicles, these mobile vehicles can move at different speeds at different times. VSMCUs (110) can collect registration information, obtain velocity information, determine re-registration distances, and determine re-registration factors. VSMCUs (110) send re-registration factors to the system. The system uses the re-registration factors to determine a modified ring-alert area for the associated VSMCU.

摘要： A communication system (10) includes a population of mobile units (24) which communicate with a control station. Communications take place between the control station and the mobile units (24) so that the system (10) may gain knowledge about the mobile units' locations. The mobile units (24) occasionally initiate such communications automatically. The control station sends data defining a target area (72, FIG. 5) to the mobile units. The mobile units (24) reside in the target areas (72) when the target areas (72) are first assigned, but the mobile units (24) are free to move. The control station transmits broadcast signals to geographically spaced apart cells (36, FIG. 2). The broadcast signals convey current data identifying the service areas covered by the cells (36). The mobile units (24) automatically initiate communications when their assigned target areas (72) do not coincide with the service areas for the broadcast signals they can receive.
