The present invention discloses an air-interface-based synchronization method, a base station, a control apparatus of the base station, and a wireless communications system. A time difference between base stations is acquired by means of signaling interworking in a non-contention based random access process of user equipment handed over between the base stations, and a time adjustment value of a non-reference base station is acquired according to reference time of a reference base station, so that the non-reference base station performs time adjustment according to the time adjustment value, thereby implementing time synchronization between the non-reference base station and the reference base station. The present invention uses an existing wireless network to simply and effectively implement air-interface-based synchronization between base stations without using an expensive synchronization device, thereby reducing construction costs and maintenance costs and achieving technical effects of cost-effectiveness and convenience. |
