Abstract

The embodiment of the invention discloses a mobility management method, user equipment and a base station. The mobility management method comprises the steps that the user equipment (UE) in a connected state receives a UE source identity from a first base station, wherein the source identity is used for uniquely identifying the UE in the first base station; the UE enters a low cost state after satisfying a low cost excitation condition, in the low cost state, the UE stores connection context of the UE in the connected state, and the UE carries out cell residence through a cell reselection criterion in a moving process; and when a first preset condition is satisfied, the UE reports the source identity to a second base station to which a second cell belongs, wherein the second cell is a serving cell currently resided by the UE. Through adoption of the method, the user equipment and the base station, after the UE enters the low cost state, the UE autonomously carries out cell reselection-based mobility, only location change information of the UE is reported, a handover process is simplified and communication resources of network equipment are saved.

Description

[0001] This application claims the priority of the international patent application filed on December 31, 2015 with the application number PCT / CN2015 / 100336 and the invention title is "Method of Mobility Management, User Equipment and Base Station", the entire contents of which are Incorporated herein by reference. technical field [0002] Embodiments of the present invention relate to the field of communications, and more particularly, to a mobility management method, user equipment, and base station. Background technique [0003] Mobility management is an important task in wireless mobile communication systems. Generally, mobility management may include mobile network handover, cell reselection, and the like of user equipment (User Equipment, UE). [0004] In the Long Term Evolution (LTE) / LTE-advanced (LTE-A) system of the 3rd Generation Partnership Project (3GPP), the UE is divided into an idle (Idle) state and a Connected state: The UE in the idle state is not connecte...
