A method and device for dividing cell clusters

Abstract

The embodiment of the invention provides a method and a device for dividing a cell cluster. The method comprises the following steps: calculating the business relevance between cells according to relevance statistical data between the cells, and finding maximum connected clusters, wherein the cells in each maximum connected cluster have strong relevance and the cells between the maximum connected clusters have weak relevance; when one cell belongs to multiple maximum connected clusters, attributing the cell to a unique cell cluster; according to geographical location information, merging cell clusters of which the scales are smaller than a cluster scale threshold to obtain the cell cluster which contains the cells according with the cell quantity threshold. According to the method and the device disclosed by the invention, the stable cell cluster which has a business sharing function and a reasonable scale is obtained by dividing each cell according to common network data and the cluster scale threshold so as to ensure that the multi-purpose cell cluster scale is controllable, and the cell cluster can be used for estimating whether the structure of a communication network is reasonable, whether the LAC (Location Area Code) boundary / BSC (Base Station Controller) boundary is reasonably divided, whether the frequency allocation is reasonable, and the like in subsequent works.

Description

technical field [0001] The present invention relates to mobile network technology, in particular to a method and device for dividing cell clusters. Background technique [0002] In mobile networks such as GSM / IS-95 / CDMA2000 / WCDMA / TD-SCDMA, a cell is the smallest network unit. In order to ensure mobility performance, a certain signal overlap area must be maintained between cells to meet handover requirements, so there is inevitably a certain correlation between adjacent cells. It is precisely because of this correlation that the various adjustment methods used in the network optimization process often not only affect the adjusted cell itself, but also affect the entire network or a part of the network. This requires that in the network analysis process, it cannot be isolated In order to deal with the problem of a single cell, it is necessary to conduct an overall analysis of a collection of closely related cells. Here, a collection of cells with certain business relevance is...

AI Technical Summary

Problems solved by technology

[0004] The existing technology has the following problems: the data required for cluster division is relatively high: the frequency reuse restriction relationship of the cell is calculated by dividing the grid, which requires the acquired frequency sweep or DT test data to be positioned between each grid , that is, each data sampling point must have latitude and longitude information in order to be located in each specific grid

Uncontrollable cluster size: In a mature cellular network, there is almost a large degree of coverage overlap and interference limitation between adjacent cells. Using existing technologies, the core urban area of ​​a large and medium-sized city is likely to be divided into a cluster. Obviously, the size of this cluster is too large, which loses the significance of cell clusters for balancing services
