Abstract:
A method of scheduling wake up times for terminals in a satellite communication system using satellite ephemeris data in order to extend battery life of terminals is described. The terminal periodically evaluates the stored ephemeris data to determine whether it is valid, recently valid, or invalid. When the ephemeris data is valid the terminal can schedule wake up times to either transmit or receive updated ephemeris data. For recently valid ephemeris data the terminal calculates BB possible satellite pass windows and schedules wake up time. For invalid data the terminal wakes and listens periodically with a period that is less than the expected satellite pass duration. It may repeat this process several times before sleeping for an amount of time less than the expected satellite pass duration and repeating. Additional gateway beacons may be used to provide ephemeris data, and satellites may also provide information on beacon locations.

Claim (Index 17):
A terminal apparatus in a satellite communication comprising:\n a receiver apparatus configured to receive ephemeris data transmitted by one or more satellites or a gateway in the satellite communication system, and configured to receive a beacon transmission from a gateway; a transmitting apparatus configured to transmit data to one or more satellites or a gateway in the satellite communication system; a position and timing module configured to estimate the terminal's position and the global time; a memory for storing the received ephemeris data; an alarm module configured to wake up the terminal apparatus from the sleep state to a wake state at one or more scheduled wake up times, and a scheduling module configured to schedule at least one wake up time based on the stored ephemeris data for transmitting data or for receiving updated ephemeris data, and to put the terminals into a sleep state upon completion of one or more terminal operations whilst in the wake state; and wherein upon wake up the scheduling module request the terminal's position and global time from the position and timing module, and is configured to determine, based upon the terminal's position and global time estimate, if the stored ephemeris data is valid, recently valid or invalid, and if the ephemeris data is valid, then the terminal is configured to either transmit data to a satellite or attempting to receive updated ephemeris data from a satellite, and if the stored ephemeris data is recently valid, then the scheduler is configured to estimate a set of possible satellite pass windows based on the stored ephemeris data and scheduling a set of warm wake up times during which the terminal is woken up to attempt to receive updated ephemeris data, and if the ephemeris data is invalid then the terminal is scheduled to go to sleep and periodically wake up and attempt to receive updated ephemeris data with a period between wake up being less than an expected satellite pass duration, and if the attempt to receive updated ephemeris data was unsuccessful then the terminal is configured to go back to sleep, and the terminal repeats operation until it successfully receives ephemeris data, and upon receiving updated ephemeris data, the ephemeris data is stored in the memory, and the scheduler schedules at least one wake up time based on the stored ephemeris data for transmitting data or for receiving updated ephemeris data and to put the terminal into a sleep state upon completion of one or more terminal operations whilst in the wake state.
