METHOD AND SYSTEM FOR IMPLEMENTING CLOCK SYNCHRONIZATION BASED ON WIRELESS MANNER

摘要

The present invention aims to provide a method and system for implementing clock synchronization based on a wireless manner. The method includes the following steps: a synchronization node searches for a base station to be synchronized by detecting an air-interface signal, and calculates the time-offset value and the frequency-offset value that the base station to be synchronized needs to adjust according to the received air-interface signal sent by the base station to be synchronized and the synchronization reference given by the synchronization reference source chosen by itself (202); the synchronization node accesses the base station to be synchronized, and reports the time-offset value and the frequency-offset value to the base station to be synchronized (203); the base station to be synchronized synchronizes its clock with the synchronization node according to the time-offset value and the frequency-offset value (204). The application of the technical solution in the present invention effectively avoids the drawbacks that a satellite synchronization signal is unable to cover the indoor area and a wired synchronization manner has a high demand for network hierarchy structure.
