Abstract
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…
