An implementation method of paging user device

Abstract

The disclosed realization method for calling UE comprises: determining predicted calling area with UE, and using MME to operate all base stations in the predicted area for UE calling; or, deciding whether the built business is high quality and the UE is high-level appointed user before calling, and executing different calling operation according to decision result. This invention reduces signaling flow obviously, saves wire / wireless resource and communication delay, and improves UE communication quality.

Description

technical field [0001] The present invention relates to the field of mobile communication, in particular to a method for realizing paging user equipment (UE). Background technique [0002] In the currently applied communication network, when the Mobility Management Entity (MME) wants to establish a service for the UE in the idle state, it needs to control all the base stations in the tracking area (Tracking Area, TA) it manages to search for the UE. call. The MME is a mobility management entity related to the signaling plane for the UE, and is usually embodied as a Serving General Packet Radio Service Support Node (SGSN) in a 3G communication network. The specific paging principle is as follows: figure 1 shown. [0003] figure 1 In , the TA managed by the MME includes UE and base station, where the black rectangle represents the UE, and the gray dot represents the base station. A switch 120 is connected between the MME 110 and the switch 130 and the switch 140, and the ...

Problems solved by technology

[0007] From the above, it can be seen that since the MME currently controls the base stations in the entire TA to perform UE paging in a unicast manner, and the number of base stations in the TA is generally considerable ; Therefore, the MME will send a large number of paging commands to the base station side switch when paging the UE. Such a large amount of signaling traffic will inevitably occupy a large amount of transmission resources such as link bandwidth, resulting in a significant impact on the system capacity of the communication network; and, the transmission The occupation of resources will also inevitably affect the communication quality of the UE such as communication delay and transmission rate, resulting in a decline in the communication quality of the UE when it communicates normally with the network side; in addition, the above-mentioned signaling traffic is large, transmission resources are occupied, and UE communication Problems such as quality degradation can also significantly reduce user satisfaction
