Cell evaluation method and device

Abstract

The embodiment of the invention provides a cell evaluation method and device, relates to the technical field of communication, and can improve the cell evaluation accuracy. The method comprises the following steps: 1, ; obtaining the total number of samples in the measurement report MR of the first priority cell and the number of standard samples, determining a second priority cell overlapped withthe coverage area of the first priority cell as a second priority neighbor cell, obtaining the weight coefficient of the second priority neighbor cell, the total number of samples in the MR of the second priority neighbor cell and the number of standard samples; according to the total number of the samples in the MR of the first priority cell and the number of the standard samples, and determining a standard sample rate of the first priority cell according to the weight coefficient of the first priority neighbor cell, the weight coefficient of the second priority neighbor cell, the total number of samples in the MR of the second priority neighbor cell and the number of standard samples, and determining the first priority cell as a standard cell when determining that the standard sample rate is greater than a preset standard rate. The scheme provided by the invention is suitable for evaluating the cell.

Description

technical field [0001] The present invention relates to the communication field, in particular to a cell evaluation method and device. Background technique [0002] At present, operators often use frequencies lower than the preset frequency as the backing network, and set the first priority and the handover threshold lower than the preset threshold, so that users preferentially camp on the frequency higher than the preset frequency and the spectrum width is higher than The second priority cell with the preset spectrum width is only in the weak coverage area of ​​the second priority cell (the weak coverage area refers to the large coverage area required by the corresponding base station, the distance between the base station and other base stations is too large, or the building is blocked. The area where the signal is weaker in the border area), the user UE will reselect or switch to the first priority cell. At present, the traditional cell-level evaluation method is to coun...

AI Technical Summary

Problems solved by technology

[0003] Because the first priority cell is a backing network, it absorbs a large number of weak coverage sampling points (sampling points in the weak coverage area), so that the proportion of weak coverage sampling points in the first priority cell is much higher than that of the second priority cell. According to the same threshold for weak coverage problem cell evaluation, a considerable proportion of the first priority cells will be judged as weak coverage cells, resulting in the coverage quality of the first priority network being wrongly underestimated

Therefore, the MR statistical data of the first priority cell cannot fully reflect the overall coverage of the first priority cell, and it is difficult to judge whether the first priority cell belongs to a weak coverage problem cell by using the existing cell evaluation scheme
