The invention brings forward a base station clock synchronization method. Any base station in a network has an optical fiber interface connected with a main synchronous base station of the base station itself and a plurality of optical interfaces connected with a slave synchronous base station of the base station itself. A certain base station is selected as a source base station and any other base stations are connected to the source station directly or in a cascading mode; and synchronization of any pair of main and slave base stations is as follows: a, an initial synchronization state of a slave base station is set as an out-of-step state and a main base station sends a local synchronization signal; b, the slave base station receives the signal and then carries out synchronization detection; and of the detection is successful, the synchronization state entrance is carried out; c, once the main base station knows that the slave base station enters the synchronization state, the main base station measures transmission delay time between the main base station and the slave base station; and after measurement is completed, the local synchronization signal is sent to the slave base station with time ahead of the transmission delay time and the slave base station switches the local synchronization signal into a received synchronization signal; and d, the slave base station carries out synchronization state detection all the time; and if the detection is not successful, out-of-step state entrance is carried out and returning to the step b is carried out.
