User equipment calling method and system

Abstract

A paging method of user device includes making the paging coverage range be part of UE total paging region when first local paging on UE is launched, launching at least one follow-up paging on UE if first local paging is failure and making coverage range of follow-up paging be part or whole of UE total paging region as at least one follow-up paging coverage range covered with region on outside of coverage range in first local paging. The system used for realizing said method is also disclosed.

Description

technical field [0001] The invention relates to the field of mobile communication, in particular to paging technology. Background technique [0002] With the development of science and technology, communication has gone through the first generation and the second generation, and entered the period of the third generation. The first-generation mobile communication system is an analog cellular mobile communication system from the mid-1970s to the mid-1980s; the second-generation mobile communication system is for the purpose of transmitting voice and low-speed data services, also known as narrow-band digital communication system ; The goal of the third-generation mobile communication system that has been developed at present is broadband multimedia communication. [0003] Among the third-generation mobile communication systems, what is currently attracting attention is the Universal Mobile Telecommunications System (Universal Mobile Telecommunications System, referred to as "...

Problems solved by technology

[0013] However, the inventors of the present invention have found that although the method of multi-TA registration can avoid the problem of UE initiating too many location update processes while moving, it also leads to the fact that when the UE is paged, it needs to be registered in the TA list. Paging is performed in all the included TA areas, so a large number of wireless resources of the cells are needed, which makes the system resources not be well utilized and increases the processing load of the network equipment

[0014] In addition, even if the UE is still only registered in one TA, in LTE, a UE with a faster moving speed generally uses a larger range of TAs. The network side must occupy more system resources when performing paging, and at the same time increase the processing load of the core network (Evolved Core Network, "ECN") equipment and access network entities of the evolved network
