A tracking area planning method and system

Abstract

The embodiment of the invention discloses a tracking region planning method. A planning area telephone traffic model parameter and a business service quality parameter are obtained. The calculation value of a single cell single carrier user number is determined according to the planning area telephone traffic model parameter and the business service quality parameter, and the simulation value of the single cell single carrier user number is obtained through simulation. According to a paging frame related parameter, the maximum user number supported by a tracking area list is determined. According to the coverage factor and the limited factor of a planning area, a single cell user number is determined. When the single cell user number is smaller than the calculation value of the single cell single carrier user number and the simulation value of the single cell single carrier user number, according to the maximum user number and the single cell user number, the coverage area of the tracking area in the tracking list is determined. The embodiment of the present invention also discloses a tracking region planning system.

Description

technical field [0001] The present invention relates to location area management technology in the field of mobile communication, in particular to a tracking area (TrackingArea, TA) planning method and system. Background technique [0002] In a mobile communication system, location area management is an important function of a cellular network, where location area settings are used to manage user mobility. For a terminal in an idle state, the core network can roughly determine the location area where the terminal is located. In this way, when a terminal needs to be paged, the core network can page the terminal within a limited area, thereby avoiding to page. [0003] Currently, a Long Term Evolution (Long Term Evolution, LTE) system is an evolution system of an existing third generation (3G) mobile communication technology. In System Architecture Evolution (SAE), the latest protocol 3GPP TS23.401vl0.0.0 defines a similar location area as a TA. The Evolved Packet Core (EPC...

Problems solved by technology

However, planning TA according to 2G / 3G LA / RA area succession will cause a mismatch between paging overhead and Tracking Area Update (TAU) overhead, and will make the TAL function unable to fully utilize, so it is necessary to perform LTE separately. Systematic TA planning

[0008] In the prior art, the method of planning a fixed number of cells or cells within a fixed area as a TA does not take into account factors such as the coverage user characteristics and service characteristics of the cells, which will make the TA planning results inaccurate and cannot make the network The TAU process and the paging process achieve a reasonable balance, which increases the performance fluctuations caused by subsequent network parameter adjustments
