Bearing process method, bearing process device and bearing process system

Abstract

The embodiment of the invention provides a bearing process method, a bearing process device and a bearing process system. The method comprises the following steps: an MME (mobility management entity) receives a path switching request message sent by an eNB (evolved NodeB), and the path switching request message is used for requesting that at least one bearing is switched to a target transmission path; the MME informs a GW (gateway) of switching the first part of the baring to the target transmission path, and keeping the second part of the bearing in an original transmission path, wherein the first part of the bearing is part of or all of the at least one bearing in the switching request message, and the second part of the bearing is part of or all of the bearing except the first part of bearing in all the bearing of UE (user equipment), and the at least one bearing belongs to the all bearings of the UE. According to the embodiment of the invention, the part of the bearing of one or a plurality of the UE can be switched to another transmission path between the eNB and the GW from one transmission path between the eNB and the GW, and the abnormal business of the UE can be avoided.

Description

technical field [0001] The present invention relates to the field of mobile communication, in particular to a bearer processing method, device and system. Background technique [0002] In a Long Term Evolution (LTE) system, there may be one or more transmission paths between an evolved base station (evolved NodeB, eNB) and a serving gateway (Gateway, GW), and the bearer on each transmission path is used to transmit a or multiple user equipment (User Equipment, UE) data. [0003] During the handover process of a UE from the source eNB to the target eNB, if the mobility management entity (Mobility Management Entity, MME) receives the identification of the bearer that the UE needs to switch the transmission path sent by the target eNB, it will notify the serving GW to switch this part of the bearer to the destination transfer path. For the bearer corresponding to the bearer identifier of the UE that the MME has not received, the MME will release it. If part of the bearers on...

AI Technical Summary

Problems solved by technology

If part of the bearers on a certain transmission path between an eNB and a GW are switched to another transmission path, the MME will also release the bearers corresponding to the UE’s bearer ID that has not been received, which may cause the UE’s Some bearers are released improperly, and the service of the UE may be abnormal
