摘要： A method and system for alerting a mobile terminal in a high-attenuation propagation environment within a mobile satellite communication network are disclosed herein. The method comprises receiving an incoming call directed to the mobile terminal, generating a paging signal in response to the incoming call, determining whether the mobile terminal has failed to receive the paging signal, and generating an alerting signal in response to the determination that the mobile terminal has failed to receive the paging signal. The system comprises a plurality of mobile terminals capable of receiving voice calls via a satellite; a satellite adapted to communicate with each of the mobile terminals, the satellite transmitting a spot beam to the mobile terminals; at least one gateway in communication with the satellite, the gateway having a first signal generator for producing a paging signal in response to an incoming call, logic for determining whether the mobile terminal has detected the paging signal, and a second signal generator for producing a high-power alerting signal in response to the logic; a first detector in the mobile terminal for detecting the paging signal; and a second detector in the mobile terminal for detecting the alerting signal.

摘要： A system and method for implementing single hop space segment terminal to terminal connections. The system includes a satellite-based radio frequency (RF) communication link for conveying multiple communication channels over the space segment via one or more spot beams. A terrestrial supervisory transceiver such as a gateway station is provided in communication with the satellite-based communication link. Mobile hand-held terminals (HHTs), herein first and second access terminals, may be located within one or more of the spot beams to communicate with one another via a single hop connection through a satellite of the system. A switch is provided for communication switching with the satellite of the system for the multiple communication channels to couple the first access terminal and the second access terminal over the space segment via one or more of the spot beams. The terrestrial supervisory transceiver or gateway is provided in communication with the satellite switch via the satellite-based communication link for implementing the single hop space segment terminal to terminal connection.
