Tracing section list updating control method and system

Abstract

The present invention relates to the wireless communication field, in particular to a tracing area list updating controlling method and a system for resolving the problems in the prior art of the complex updating controlling and the enormous paging loading in the wireless communication system caused by the enormous TA list which is updated and controlled by the UE and core network control node. Inthe present invention, when the UE supervises that the duration time of leaving a TA reaches the presetting time length, the TA identification corresponding to the TA list is deleted, and the deleting result is informed to the core network control node; the core network control node synchronistically deletes the TA list local stored the UE according to the deleting result. The technical proposalof the present invention is adopted to control the size of the TA list, thus the complexity of updating controlling the TA list is reduced, the performances of the UE and the core network control nodeare improved, and simultaneously the paging area is also reduced and the paging loading of the wireless communication system is reduced.

Description

technical field [0001] The present invention relates to the field of wireless communication, in particular to a tracking area list update control method and system. Background technique [0002] TA (Tracking Area, tracking area) is a concept proposed in the process of 3G network SAE (System Architecture Evolution, system architecture evolution), which is similar to LA (Location Area, location area) and RA (Routing Area) in 2G / 3G , routing area) concept. Since the SAE system is all based on the PS (Packet Switched, Packet Switched) domain, only one concept of location area, that is, TA, can be proposed in the SAE system. The concept of only one TA simplifies the hierarchy of location areas in the SAE system and the complexity of update control. [0003] like figure 1 As shown, in a 3G network, a roaming area may include multiple TAs, and a TA may include multiple cells, each TA has a unique corresponding TA ID, and each cell carries its TA ID in its broadcast message . T...
