The present invention relates to the field of wireless communication network technology, and disclosed are a synchronization device and method for solving the problem of high cost of absolute time synchronization between base stations. The method of the present invention comprises: when the base station to be synchronized is in sync with a frame number of a reference base station and in sync with a frame timing, an acquisition module acquires a first frame number and a first frame timing; the acquisition module acquires time information provided by a timing device of the base station to be synchronized so as to acquire a second frame number and a second frame timing by converting the time information; a computation module acquires the deviation between the first frame number and the second frame number and the deviation between the first frame timing and the second frame timing, and a synchronization module achieves absolute time synchronization with the reference base station based on the frame number deviation and the frame timing deviation, the reference base station being used to achieve the absolute time synchronization with the base station to be synchronized. The solution provided in the embodiment of the present invention is suitable for synchronization between base stations. |
