BASE STATION AND CLOCK SYNCHRONIZATION METHOD THEREOF

摘要

An enhanced base station and clock synchronization method are provided. The method includes scanning to discover a satellite transmitting a satellite signal and a master base station providing clock synchronization signal, entering, when a satellite having a signal that fulfills predetermined conditions is found, a master mode for receiving the satellite signal to acquire clock synchronization and transmitting a clock synchronization signal to at least one slave base station, and entering, when no satellite having a signal that fulfills the predetermined conditions is found, a slave mode for receiving the clock synchronization signal from the master base station to acquire clock synchronization. The method allows the base station to switch between the master and slave modes dynamically according to variation of the communication environment, resulting in efficient clock synchronization.

1. A method for controlling a mode of a communication entity, the method comprising:
discovering a satellite; entering a master mode when the satellite is discovered; and entering a slave mode when no satellite is discovered, wherein, when the communication entity enters the slave mode, the communication entity receives a clock synchronization signal from other communication entity.
