SWITCH METHOD, COMMUNICATIONS DEVICE AND COMMUNICATIONS SYSTEM

摘要

The present invention provides a handover method, which includes: obtaining, by an obtaining node, mobility management entity pool MME pool information which is sent by a donor station of the access node and is used for identifying a mobility management entity MME to which a user equipment UE is attached; and initiating, by the access node, handover for the UE according to the MME pool information used for identifying the MME to which the UE is attached. The present invention further provides a communication device and a communication system. According to the technical solutions provided by the embodiments of the present invention, the handover may be successfully performed through MME pool information that is sent by the donor station of the access node and is of the MME to which the UE is attached.
