Paging method and device based on tracking area list

Abstract

The invention provides a paging method and apparatus based on a tracking area list. The problem that when an MME pages UE, paging is performed in a tracking area included by the whole tracking area list so that the signaling load of paging channels of a base station is heavy is solved. The method includes steps: obtaining a TAI record list relates to to-be-paged UE, wherein the TAI record list comprises tracking area sets of a plurality of historical periods, the tracking area set of each historical period comprises tracking areas in which the motion frequency of the UE is greater than a first preset threshold in the historical period, and statistics of the tracking areas is performed in advance; determining the period which the current time belongs to, and searching a first tracking area set of the historical period corresponding to the current period in the TAI record list; and selecting the first tracking area set and the MME as the intersection of M tracking areas included by the tracking area list distributed by the UE, obtaining N tracking areas which the UE currently and most possibly reside in, and performing first paging on the UE in the N tracking areas.

Description

technical field [0001] The present invention relates to the technical field of communications, in particular to a tracking area list-based paging method and device. Background technique [0002] Since the mobility management entity (Mobility Management Entity, MME) paging the user equipment UE is based on the tracking area list, the MME needs to page the UE in all tracking areas TA included in the entire tracking area list, and the MME will The network sends the paging message to the UE to all base stations included in the entire tracking area list. All base stations need to send paging messages on the paging channel, regardless of whether the UE is currently in the coverage area of ​​the base station, which will increase all The paging load of the base station. In the mobile communication network, the paging channel resources of the base station are very precious, which will cause when there are many users in the network, due to the limited paging channel resources, the tr...
