Embodiment Construction
[0054] In order to make the technical problems, technical solutions and advantages to be solved by the present invention clearer, the following will describe in detail with reference to the drawings and specific embodiments.
[0055]The present invention aims at the problem of low accuracy of the measurement results of the existing over-coverage analysis method, and provides a cell over-coverage analysis method, through the analysis of drive test data, analyzes the site distribution in the surrounding area of the cell, and judges the rationality of cell coverage. Therefore, it is simple, efficient, and intuitive to determine whether there is over-coverage in the cell, and the accuracy is improved.
[0056] Such as figure 1 As shown, a method for analyzing the over-coverage of a cell in the embodiment of the present invention includes:
[0057] Step 101 , acquiring drive test data measured at all sampling points when a drive test terminal uses a cell to be tested as a servin...

The invention provides a method and a device for analyzing cell over coverage, which relate to the technical field of wireless communication. The method comprises steps: roadside data acquired and measured by a roadside terminal at all sampling points with a to-be-detected cell as a service cell are acquired; according to the roadside data at each sampling point, the distance between each sampling point and a base station corresponding to the to-be-detected cell is determined, the number of cells in a range with the sampling point as a circle center and the distance as a radius is counted, and the cell number is used as an over coverage index for the sampling point; and according to the over coverage indexes for all sampling points, whether over coverage exists in the to-be-detected cell is judged. According to the scheme of the invention, through analysis on the roadside data, a site distribution condition around the cell is analyzed, the cell coverage rationality is judged, whether over coverage exists in the cell is determined, the method is easy and simple to operate, high-efficiency and intuitive, and the accuracy is enhanced.
Description
technical field [0001] The present invention relates to the technical field of wireless communication, in particular to a method and device for analyzing cell overcoverage. Background technique [0002] With the gradual expansion of wireless networks, problems with the performance of wireless devices have gradually emerged. Especially with the increase in the density of base station construction in cities in the past two years, antenna performance issues have also begun to attract more and more attention from operators. In particular, due to the gradual aging of antenna equipment, the vibrator or feeder line technology of the centralized collection antenna is not up to standard, resulting in a serious decline in antenna gain, which greatly affects the depth of network coverage and customer perception. [0003] For this problem, the following methods are generally used to troubleshoot and optimize: [0004] One is to use the drive test method to reversely calculate the anten...
