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

[0022] The main technical idea of ​​the present invention is that in some occasions, the range of movement of the UE within the location update timing period is limited, and the UE is often only in a certain cell of the paging location area. Therefore, according to the mobility of the UE, the present invention preserves The historical information of the cell where the UE is in the last few calls or the location update is obtained. By comparing the historical information of the cell of the last few times (such as 2 times), it is confirmed whether the UE is in a static state, and the paging is classified. If In the static state, paging is performed at the cell level. The system first initiates paging to the cell where the UE is located. If the UE cannot be paged, it will page all cells in the entire paging location area; otherwise, if it is in the mobile state, Then the paging system starts paging for the cells in the entire paging location area.

Abstract

The invention advances a method for calling user terminal in wireless communications system; with the method, calls are classified according to the mobility of UE; the system starts calling all communities in the position area for calling the mobile UE, and the system starts calling in the community in which the UE is located first for calling static UE and then calls all communities in the position area if the UE could not be called. By adopting the method, calling information flow volume could be reduced to decrease the load of every base station controller and the blockage of information is deduced to promote the call completion rate; at the same time, a large amount of call channel resource could be saved, especially for most users in prosperous downtown or office buildings who are static with limited wireless resources, the effect is obvious.

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...
