Embodiment Construction

[0032] The inventor noticed during the invention that:

[0033] figure 1 It is a schematic diagram of the handover process of the X2 interface. As shown in the figure, in the handover process of the X2 interface, only the source eNB (source evolved base station) and target eNB (target evolved base station) participate in the handover preparation process, and has nothing to do with the MME. The source eNB is sending to The handover request message of the target eNB includes the bearer information of the UE. After receiving this message, the target eNB reserves bearer resources for the UE, and returns the bearer acceptance result to the source eNB in ​​the handover request response. After the UE is handed over to the target cell, the target eNB sends a path request process to the MME. According to the IE (Information Element, Information Element) in the path request message, the MME can determine the bearers successfully accepted by the UE in the target eNB and the bearers not ...

Abstract

Disclosed are a processing method for bearer admission during S1 interface handover, and a mobility management entity. The method includes that: a mobility management entity confirms it is engaged in a preparation process for S1 interface handover; once said handover preparation process is complete, the mobility management entity confirms whether the default bearers of a user equipment have been successfully admitted to a target cell. With the invention, any problem of default bearers not all being successfully admitted to the target cell can be discovered during the handover preparation stage, and the handover can thus be terminated, and the source base station can therefore perform such processing as selecting other target cells for the user equipment. If the user equipment is detached from the network because of an admission failure of the default bearers only after handover to the target cell is complete, service continuity will be affected. This problem can be avoided with the method in the present invention.

Description

technical field [0001] The present invention relates to wireless communication technology, in particular to a bearer acceptance processing method and a mobility management entity device during an S1 interface switching process. Background technique [0002] According to the existing agreement, if the default bearer of a certain PDN (Packet Data Network, packet data network) connection is not accepted by the target eNB (evolved base station), and the UE (User Equipment, user equipment) has multiple active PDN connections , the MME (Mobility Management Entity, mobility management entity) considers that all bearers of this PDN connection have failed and initiates a PDN connection deactivation process to deactivate the entire PDN connection. If all default bearers are not accepted by the target eNB, the MME will detach the UE. [0003] In the prior art, the X2 interface handover preparation process does not require the participation of the core network. At the same time, the ba...
