Low power mode in a satellite-based broadcast data service
First Claim
1. A satellite receiver, comprising:
- a satellite receiver controller to retrieve a transmission interval and an epoch time from a wakeup list, select a next wakeup time, enter a sleep mode according to said transmission interval, exit said sleep mode according to said transmission interval, and receive a satellite transmission according to said epoch time;
wherein said transmission interval is an amount of time said satellite receiver is to remain in said sleep mode between expected transmissions and said epoch time is an instant, after the satellite receiver awakes from the sleep mode, at which said satellite receiver expects broadcasts to be transmitted.

Abstract
A satellite system controller for a satellite system can comprise a receiving module, an interval selector, an epoch selector, and a scheduler. The receiving module can receive, from a transmission originator device, a set interval request message requesting the satellite system controller set a transmission interval and an epoch time for a satellite receiver, the transmission interval being an amount of time the satellite receiver is to remain in a sleep mode between expected transmissions and the epoch time being an instant at which the satellite receiver is to expect a satellite transmission. The interval selector can determine, based on the transmission interval, a sleep mode cycle for the satellite receiver. The epoch selector can select the epoch time according to the sleep mode cycle and the scheduler can schedule the satellite transmission with the satellite system at approximately the epoch time and according to the sleep mode cycle.
