SYNCHRONIZATION METHOD AND DEVICE FOR AIR INTERFACE IN TIME DIVISION SYSTEM

摘要

The present invention relates to communication technical field, and provides a synchronization method and device for air interface in time division system, said method includes: determining whether there is an base station out of step according to the System Frame Number (SFN) observed time difference between two cells in the measurement report which is reported by the terminals in the neighboring cells; if there is a base station out of step, a synchronization is performed for the un-synchronous base station. Using the present invention, a desynchronization of base station caused by the slow drift of the clock reference source can be detected and an air interface synchronization for the system can be realized.
