Synchronization method, terminal and base station

The invention relates to the field of communication technologies and discloses a synchronization method, a terminal and a base station for solving the technical problem that the time of the terminal in the prior art is not precise enough. The synchronization method is applied to the terminal and comprises the following steps of receiving a first synchronous message, which is transmitted by a positioning device, wherein the first synchronous message includes first position information of the positioning device; receiving a second synchronous message, which is periodically transmitted by a synchronizer, wherein the second synchronous message includes current time of the synchronizer and second position information of the synchronizer, and the synchronizer is pseudo satellite equipment or the base station; and synchronizing the current time of the terminal according to the first position information, the second position information and the current time of the synchronizer.
