Mobility Management Method, User Equipment, and Base Station
First Claim
1. A mobility management method, comprising:
- allocating, by a first base station to which a first cell belongs, a source identifier to user equipment (UE) in a connected state in a first cell, wherein the source identifier comprises a first UE identifier used to identify the UE in the first base station; and
storing a connection context of the UE in the connected state after determining that the UE enters a low-overhead state, wherein the UE enters the low-overhead state when satisfying a preset activation condition, and the UE in the low-overhead state stores the connection context and camps on a cell according to a cell reselection criterion in a moving process.

Abstract
Embodiments of the present invention disclose a mobility management method, user equipment, and a base station. The mobility management method may include: receiving, by the user equipment (UE) in a connected state, a source identifier of the UE from a first base station, where the source identifier is used to uniquely identify the UE in the first base station; entering, by the UE, a low-overhead state after satisfying a low-overhead activation condition; storing, by the UE in the low-overhead state, a connection context of the UE in the connected state, and camping on a cell according to a cell reselection criterion in a moving process; and reporting, by the UE when satisfying a first preset condition, the source identifier to a second base station to which a second cell belongs, where the second cell is a serving cell on which the UE currently camps.

11. A mobility management method, comprising:
-
receiving, by a second base station to which a second cell belongs, a source identifier reported by user equipment (UE) in a low-overhead state, wherein the UE in the low-overhead state stores a connection context of the UE in a connected state and camps on a cell according to a cell reselection criterion in a moving process, a first cell is a serving cell of the UE when the UE enters the low-overhead state, a second cell is a current serving cell of the UE, and the source identifier comprises a first UE identifier used to identify the UE in a first base station to which the first cell belongs; and sending the first UE identifier to the first base station according to the source identifier, to instruct the first base station to learn that the current serving cell of the UE is the second cell. - View Dependent Claims (12, 13)
