Embodiment Construction

[0021] In order to make the specific technical solution of the present invention clearer, further description will be made below in conjunction with specific implementation methods and accompanying drawings.

[0022] Such as figure 1 As shown, the embodiment of the present invention provides a handover method, the method includes:

[0023] Step 101: the access node obtains the information sent by the host site of the access node for identifying the MME pool of the MME pool to which the UE under the coverage of the access node is attached;

[0024] Step 102: When the UE needs to be handed over, the access node performs UE handover according to the information of the MME pool used to identify the MME to which the UE is attached.

[0025] In the embodiment of the present invention, the access station may be the RN in the relay system, or the Evolved UMTS Terrestrial Radio Access Network (Evolved UMTS Terrestrial Radio Access Network, E-UTRAN) deployed Home evolution Noed B, HeNB...

Abstract

The present invention provides a handover method, comprising: an acquisition node acquires the information sent by the host site of the access node for identifying the mobility management entity pool MME pool information of the mobility management entity MME to which the user equipment UE is attached; the access node The handover of the UE is performed according to the information of the MMEpool used to identify the MME to which the UE is attached. The invention also provides a communication device and a communication system. According to the solution provided by the embodiment of the present invention, the successful handover can be performed through the MME pool information of the MME attached to the UE sent by the host site of the access node.

Description

technical field [0001] The present invention relates to the technical field of communication, in particular to a switching method, a communication device and a communication system. Background technique [0002] In the Long Term Evolution (LTE) system, in the intra-Evolved UMTS Terrestrial Radio Access Network (intra-Evolved UMTS Terrestrial Radio Access Network, intra-E-UTRAN), based on different handover reference points, there can be two Handover type, including handover based on X2 interface (X2 handover) and handover based on S1 interface (S1 handover). [0003] The X2 handover takes the X2 interface between the source base station (eNB) and the target eNB as a reference point. During the handover process, the Mobility Management Entity (MME) attached to the user equipment (User Equipment, UE) will not change, that is The X2 handover presupposes the existence of an S1 interface between the source eNB and the MME to which the UE is attached, and the existence of an S1 i...
