Problems solved by technology

[0012] It can be seen from the above that when the system paging the UE, the paging range is determined by the paging location area. The larger the paging location area is, the more Node Bs are covered. Too many, the number of user terminals is too large, and a large number of paging will lead to excessive paging message traffic of Node B, which will cause excessive system load and affect the system call throughput. If the paging location area is set too much Small, too many paging location areas in the network will cause frequent location updates of user terminals, waste corresponding signaling resources, and increase the uplink load of the network
Therefore, the method for processing paging messages in the prior art is difficult to solve the contradiction between paging load overload and frequent location updates

Embodiment Construction

[0028] The main technical idea of ​​the present invention is to record the information of the serving cell and the neighboring cell during the call of the UE within a certain period of time, and record the cell history information of the UE whose location is updated most recently. When the CN initiates paging to a location area in the RNC, the RNC first analyzes the UE's location update or the cell history information of the last call record, if the location update cell exists in the serving cell or neighboring cell of the last or several calls , or the time of the latest call is less than a certain time limit, then initiate a paging request to the serving cell and neighboring cells of the last call at the same time, if the UE cannot be paged, then page all cells in the entire location area of ​​the RNC.

[0029] The main steps of realizing the method of the present invention are as follows:

[0030] S101, setting a dynamic database in the RNC to save the cell history informat...

Abstract

The invention discloses a method used for realizing paging to user terminal in a wireless communication system, when CN initiates paging to a location area in RNC, RNC first analyses location update of UE or historical information of a subdistrict of the most recent call records; when location updating subdistrict is in one or several service subdistricts or adjacent subdistricts of the most recent calls, or occurred time of the most recent call is lower than a certain time limit, paging request is initiated to the service subdistricts or the adjacent subdistricts of the most recent call at the same time; and when the UE can not be paged, paging is initiated to all of the subdistricts in the entire location area of RNC. The invention initiates paging to UE according to the service subdistricts or the adjacent subdistricts in call time, and effectively saves paging bandwidth.

Description

technical field [0001] The invention belongs to the field of wireless communication, in particular to a method for realizing paging for a user terminal in a wireless communication system. Background technique [0002] In a wireless communication system, there are always some UEs (user terminals) in an idle state with neither uplink transmission service nor downlink reception service. When there is a service for an idle UE on the network associated with the base station, for example, there is a voice service request to the UE, the base station often needs to notify the idle UE to start and prepare to receive the corresponding voice service through paging. business. [0003] The wireless communication system divides different base stations in the service area into different paging location areas. A paging location area may cover dozens or even hundreds of cells, and some base stations may belong to two different paging location areas. [0004] The paging location area mainly...
