The present disclosure discloses a method, apparatus and system for implementing an X2 handover. In the scheme of the present disclosure, a Base Station (BS) initiates, after having determined the need for a handover and detected that there exists an X2 connection between the BS and a target BS and that the BS and the target BS are within the management scope of a same MME, an X2 handover, if it is determined that there exists a connection between the target BS and the serving gateway connected with the BS according to acquired serving gateways connected with an other BS. Here, the term “an/the other BS” refers to one different from the BS determines the need for a handover, and includes the target BS designated for a handover. By using the scheme provided herein in which a determination on whether an X2 handover condition is currently met, that is, whether there exists a connection between the target BS and the serving gateway connected with the BS, is accurately made before the BS initiates a handover, and an X2 handover is initiated by the BS when the X2 handover condition is met, the present disclosure effectively avoids the possibility of the failure of an X2 handover, increases the success rate of an X2 handover, and provides excellent user experience.
