Patent ID: 8824343

Claim:
A method for implementing synchronization among micro-base stations, comprising presetting synchronization information in a micro-base station, and further comprising: intercepting a wireless reference signal of an air interface and selecting a most precise synchronization reference object according to an intercepted wireless reference signal by the micro-base station, wherein the most precise synchronization reference object is a synchronization reference object having minimum error with a clock of a Global Navigation Satellite System (GNSS); and implementing synchronization processing by the micro-base station through the wireless reference signal of the selected synchronization reference object; wherein the synchronization information comprises a synchronization state value or comprises a synchronization state value and a self-synchronization indication value; and the micro-base station determines the most precise synchronization reference object through the synchronization information; and the selecting a most precise synchronization reference object comprises: when a synchronous signal from a satellite is intercepted, selecting the satellite as the synchronization reference object; otherwise, when a wireless reference signal from a macro-base station is intercepted, selecting the macro-base station as the synchronization reference object; otherwise, when a wireless reference signal from other micro-base stations is intercepted, selecting a micro-base station with a self-synchronization indication value No as the synchronization reference object from the intercepted micro-base station and the micro-base station; when there are two or more than two micro-base stations with the self-synchronization indication value No, selecting a micro-base station with a minimum synchronization state value as the synchronization reference object from the two or more than two micro-base stations.
