Reconfiguration method and system for tracking zone, user device and mobility managing entity

Abstract

The method comprises: a) user end (UE) measures its own current speed level; when UE determines to reconfigure TA level corresponding to the UE, it sends the speed level to mobility management entity (MME) in the evolving core network to request the MME to reconfigure the TA level; b) after receiving the speed level, the MME reconfigures TA level for the UE, and sends the reconfigured TA level to the UE; UE updates its TA level to the received TA level. The invention also provides system, UE an MME used for reconfiguring TA level.

Description

technical field [0001] The present invention relates to user equipment (UE) mobility management technology in the evolved third-generation (3G) communication system, and in particular to systems, user equipment, and mobility management for reconfiguring Tracking Area (TA) levels in the evolved 3G network Entity (MME) and TA level reconfiguration methods. Background technique [0002] In recent years, with the development of communication technology, the use of 3G network system has become more and more common. Fig. 1 shows a simplified diagram of the system structure of a 3G network. Referring to Fig. 1, a 3G network is mainly composed of a radio access network (RAN) and a core network (CN). Among them, RAN is responsible for processing functions related to wireless; while CN is responsible for processing services such as voice calls and data connections, and realizes switching and routing with external networks such as the public telephone network (PSTN) and the Internet ...

AI Technical Summary

Problems solved by technology

However, for the current evolved 3G network, the problem of how to measure the change of UE's moving speed is still to be solved, so dynamic configuration at the TA level based on the change of UE's moving speed is still not possible
