Problems solved by technology

[0008] From this we can see that in the existing methods for determining the coverage of a cell, either it needs a lot of manpower and material resources to measure, or it needs a lot of mathematical statistics calculations, and neither of them can Accurately determine cell-level coverage in real time

Embodiment 1

[0098] In this embodiment, the sampling point cells can be classified according to the collected and selected average downlink level of the source cell, for example, the average downlink level value of the source cell is divided into several level intervals, and according to the collected The average downlink level of the source cell corresponding to the point cell determines the level interval of each sampling point cell, that is, each sampling point cell is divided into different types of level intervals, so as to obtain the classification information of each sampling point cell (which can be called is the interval classification information of the average downlink level of the source cell), and then the coverage of the source cell can be obtained according to the interval classification information of the average downlink level of the source cell of each sampling point cell.

[0099]In a mobile communication system, for example, in a GSM network, the range of the average dow...

Embodiment 2

[0117] In this embodiment, the average number of sampling points in the three interference intervals of the source cell in the collected and selected raw data can be calculated separately to obtain the average number of sampling points in the corresponding interference interval, according to the source cell Each sampling point sub-district is classified according to the size relationship between the number of sampling points in the three interference intervals of each sampling point sub-district and the average sampling point number in the corresponding interference interval, and the classification information of each sampling point sub-district (which can be referred to as classification information of the number of sampling points); and then obtain the coverage of the source cell according to the classification information of the number of sampling points of each sampling point sub-district.

[0118] see Figure 5 , Figure 5 It is a flowchart of a method for classifying sa...

Embodiment 3

[0135] In this embodiment, the sampling point cells can be classified according to the collected and selected average downlink level of the source cell, for example, the average downlink level value of the source cell is divided into several level intervals, and according to the collected The average downlink level of the source cell corresponding to the point cell determines the level interval of each sampling point cell, that is, each sampling point cell is divided into different types of level intervals, so as to obtain the classification information of each sampling point cell (which can be called is the average downlink level interval classification information of the source cell); and, the source cell in the collected and selected raw data can perform mean value calculation on the number of sampling points in the three interference intervals of each sampling point cell to obtain the corresponding interference interval The average number of sampling points, according to th...

Abstract

The invention discloses a method and a device for confirming a cell coverage area. The method comprises the following steps: step A, collecting and choosing initial data needed for confirming a coverage area of a source cell from an operation and maintenance center system; step B, acquiring category messages of each sample cell after classifying each sample cell according to the collected and chosen initial data needed for confirming the coverage area of the source cell; and acquiring the coverage area of the source cell according to the category messages of each sample cell. The invention can accurately confirm the coverage area of the source cell in time, and can judge the deviation of the coverage area of the source cell through a plurality of coverage areas of the source cell, which are obtained by comparing the initial data which are in different time quantum and are collected and chosen from the OMC system, thereby helping an operator timely and effectively discover the deviation of the coverage area of the source cell and better performing network maintenance and optimization.

Description

technical field [0001] The invention relates to cell coverage technology in mobile communication, in particular to a method and device for determining cell coverage. Background technique [0002] In the past two decades, land wireless mobile communication has achieved rapid development. Communication between mobile phone users and base stations is carried out in the form of electromagnetic wave propagation. In a mobile communication network, there are usually a large number of cells, and each cell has its own coverage area. One of the important factors affecting the quality of mobile communication is the problem of cell coverage, such as over-area coverage, critical coverage, under-coverage, etc. , therefore, how to determine the coverage of each cell in a mobile communication network including a large number of cells is very important for network optimization. [0003] In the prior art, there are generally two ways to determine the coverage of a cell: [0004] 1) Drive t...
