Abstract
A method and an apparatus for network synchronization in a satellite communication system is provided. a satellite station receives a superframe start timing (SST) and an initial counter value from a center station, and receives traffic information sent from a terminal station at a time determined based on the SST. Then, the satellite station generates a compensation value for the SST upon receiving the traffic information, and corrects the SST in accordance with the compensation value.
Claims15
A method for network synchronization in a satellite communication system, the method comprising:
- receiving, by a satellite station, a superframe start timing (SST) and an initial counter value from a center station;
- receiving, by the satellite station, traffic information sent from a terminal station at a time determined based on the SST;
- and
- generating, by the satellite station, a compensation value for the SST upon receiving the traffic information, and correcting the SST in accordance with the compensation value.
A satellite apparatus in a satellite communication system, comprising:
- a network interface device;
- and
- a processor,
- wherein the processor is configured to perform:
- an operation of receiving a superframe start timing (SST) and an initial counter value from a center station through the network interface device;
- an operation of receiving traffic information sent from a terminal station at a time determined based on the SST through the network interface device;
- and
- an operation of generating a compensation value for the SST upon receiving the traffic information, and correcting the SST in accordance with the compensation value.
