Title: TIME SYNCHRONIZATION METHOD, DEVICE AND SYSTEM
Abstract:
Provided are a time synchronization method, device and system, relating to the field of communications. The method comprises: determining a target base station from base stations adjacent to a source base station; according to a pre-set switching condition, determining, from first user equipments (UE) accessing the source base station, a UE to be switched needing to be switched to the target base station; triggering the UE to be switched to switch from the source base station to the target base station; and during the switching process of the UE to be switched, performing time synchronization with the target base station. In the present invention, a UE to be switched is triggered to switch to a pre-determined target base station, so as to achieve time synchronization with the target base station; the problem, in the relevant art, of lower flexibility of time synchronization between base stations is solved; and the flexibility of time synchronization between a source base station and a target base station is improved. The present invention is used for time synchronization.
