Problems solved by technology

Neglecting these subtle differences to plan the location area will cause a certain discount to the overlapping coverage effect of the TA-LA dual network location area
[0006] At present, 4G voice is implemented through CSFB (Circuit Switched Fallback), and CSFB requires overlapping coverage of location areas of TA-LA dual networks, which puts forward higher precision requirements for the determination of TA range and LA range. The "sprinkling method" cannot meet the requirements

Embodiment 1

[0048] An embodiment of the present invention provides a location area division optimization method, such as figure 1 As shown, the processing flow of the method of this embodiment includes the following steps:

[0049] Step 101 , according to the number of handovers between cells within the range to be optimized within a preset period of time, construct a matrix of the number of handovers between cells and a matrix of the total number of handovers between cells.

[0050] The method of this embodiment introduces a large number of historical mobile behaviors of users on the live network, which can truly reflect the wireless coverage of the optimized target network, and perform more refined optimization on the basis of the division of existing location areas within the scope to be optimized. Make it easier for the network to achieve TA-LA wireless coverage overlap and improve the voice perception of high-value 4G users.

[0051] Assuming that the number of cells within the scop...

Abstract

The embodiment of the invention discloses a location area division optimization method and device. The method comprises the steps of establishing an inter-cell switching time matrix and a cell total switching time matrix according to the switching time among cells in a to-be-optimized range within preset duration; calculating a high switching threshold according to the switching time among the cells in the to-be-optimized range; entering an iteration process, carrying out establishment to obtain a current cell-location area setting matrix, in the cells of which switching total time is greater than or equal to the high switching threshold, positioning to-be-adjusted cells of which loyalty for attribution location areas is the lowest; obtaining location areas to which the to-be-adjusted cells currently belong, and the highest loyalty location areas corresponding to the highest loyalty of the to-be-adjusted cells for the location areas, adjusting and recording the location areas to which the to-be-adjusted cells currently belong as the highest loyalty location areas, judging whether the iteration process is finished or not, if the iteration process is not finished, circularly carrying out the iteration process until it is judged that the iteration process is finished.

Description

technical field [0001] The present invention relates to communication technology, in particular to a location area division optimization method and device. Background technique [0002] In the mobile communication cellular network, it is necessary to divide the location area in the public land mobile network (PLMN, Public Land Mobile Network), and the location area includes the second / third generation mobile phone communication technology (2 / 3-Generation wirelesstelephone technology, 2 / 3G) network Location Area (LA, Location Area) / routing area (RA, RoutingArea), or the tracking area (TA, Tracking Area) in the fourth-generation mobile communication technology (4-Generation wireless telephone technology, 4G) network, location The area is the smallest area range that the network can determine when the user is idle. The division of location area needs to consider the paging capacity and traffic load, and try to define the boundary on the natural obstacle of geographical space, ...
