Problems solved by technology

[0003] But how to judge the coverage, in the past, optimizers could only rely on drive test data and experience to judge the coverage problem. The efficiency of coverage optimization is low and depends on personal experience, and there is no quantification method available.

Embodiment Construction

[0028] The present invention will be described in detail below in conjunction with the accompanying drawings.

[0029] Such as figure 1 As shown, the embodiment of the coverage evaluation method of the present invention includes the following steps:

[0030] Step 102, estimating the coverage of each cell according to the cell information;

[0031] Step 104, selecting a cluster comprising multiple cells for the core cell according to the coverage of each cell;

[0032] Step 106, selecting an overlay cell from intra-cluster and out-cluster cells including different frequency bands;

[0033] Step 108, calculating the equivalent interference area of ​​the core cell to the overlay cell outside the cluster according to the coverage of the cell;

[0034] Step 110, calculating the coverage efficiency of the core cell according to the equivalent interference area.

[0035] Such as figure 2 As shown, in step 102, according to the latitude and longitude of the antenna of the cell a...

Abstract

The invention discloses a method, a device and a system for covering assessment. The method comprises that a covering range of each district is assessed in advance according to information of each district and a cluster containing a plurality of districts is selected for a core district according to the covering range of each district; a covered layer district is selected from districts inside the cluster and outside the cluster, wherein the districts contain different frequent channels; equivalent interference area of the core district to the covered layer district outside the cluster is calculated according to the covering range of each district; and covering efficiency of the core district is calculated according to the equivalent interference area. According to the method, the device and the system for the covering assessment, the equivalent interference area of the core district to the district outside the cluster and the covering efficiency of the district are calculated, an over covering problem is quantized, the method, the device and the system can be used for assessment of whole network covering health degree and selection of an over covering problem district, covering optimization work efficiency is improved and judgment of the over covering problem is prevented from being influenced by human factors.

Description

technical field [0001] The present invention relates to a wireless technology, in particular to a coverage evaluation method, device and system. Background technique [0002] With the development of cities and the surge in traffic demand, a large number of new stations are connected to the network every year, various network optimizations and adjustments, and changes in the wireless environment make the network coverage constantly changing. According to the principle of micro-cell frequency reuse, the coverage of the cell must be adjusted in time and reasonably controlled, otherwise serious in-band interference will be caused. Operators pay more and more attention to the optimization of 2G network structure, and realize that the over-coverage problem is an important factor affecting the complexity of the structure, and is the main factor causing in-band interference on the existing network. [0003] But how to judge the coverage, in the past, optimizers could only rely on d...
