[0021] In order to make the purpose, technical solution and advantages of the embodiments of the present invention clearer, the technical solution in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0022] In order to solve the problems of long time consumption, inaccurate problem location and large workload caused by the use of road test for network coverage anomaly detection in the related art, the embodiment of the present invention provides an antenna feed problem verification solution. In the embodiment of the present invention, M1 first related cells of the target cell are determined according to the overlapping coverage area between the target cell and N adjacent cells. Among them, the N adjacent cells can be N cells that are relatively close to the target cell in physical location. The M1 first related cells screened out according to the overlapping coverage area can be the M1 cells that are most relevant to the physical location of the target cell. Afterwards, according to the measurement report of the target cell, the M2 second related cells that are actually related to the target cell are determined. In theory, the cells related to the physical location of the target cell are relatively consistent with the cells actually related in the measurement report. Based on this, if the correlation between each first related cell of the target cell and each second related cell is low, it can be determined that the target cell has an antenna feed coverage anomaly problem. In the embodiment of the present invention, when determining each first related cell of the target cell, a Monte Carlo algorithm can be used, which can greatly reduce the difficulty of calculation and can quickly, accurately and effectively discover the coverage anomaly problems existing in the network. The embodiments of the present invention will be described in detail below with reference to the accompanying drawings.

[0023] Figure 1 FIG. 1 is a flow chart of a method for checking antenna feeder problems provided by an embodiment of the present invention. Figure 1 The processing steps of the method include:

[0024] 101, determine N overlapping coverage areas of the target cell and N adjacent cells respectively. Optionally, the above-mentioned N adjacent cells may be cells that are relatively close to the target cell in physical location. In some embodiments, each cell within a preset distance range of the target cell may be determined as an adjacent cell of the target cell. Afterwards, the overlapping coverage area of ​​the target cell and each adjacent cell is calculated. Among them, when calculating the overlapping coverage area of ​​the target cell and each adjacent cell, since the antenna transmission of each cell is an irregular pattern, it is difficult to actually calculate the coverage area of ​​each cell. Therefore, in an embodiment of the present invention, the target cell and each adjacent cell are simulated as a sector, and then the Monte Carlo algorithm is used to calculate the overlapping coverage area of ​​the target cell and each adjacent cell. The specific process can be referred to the detailed description below.

[0025] 102. According to the N overlapping coverage areas, M1 first related cells of the target cell are determined from the N adjacent cells, where M1 is less than N. Optionally, after obtaining the N overlapping coverage areas of the target cell and the N adjacent cells, M1 first related cells of the target cell may be determined from the N adjacent cells according to the obtained overlapping coverage areas. In some embodiments, the M1 cells with the largest overlapping coverage areas may be determined as the first related cells of the target cell. Optionally, the M1 first related cells are cells with the highest correlation with the physical location of the target cell.

[0026] 103. Determine M2 second related cells of the target cell according to the measurement report of the target cell. In the embodiment of the present invention, the measurement report of the target cell is obtained. Then, the M2 cells that are actually most related to the target cell can be determined according to the measurement report of the target cell as the second related cells. For example, the M2 neighboring cells with the strongest signal strength in the measurement report of the target cell can be used as the second related cells of the target cell.

[0027] 104. According to the correlation between the M1 first related cells and the M2 second related cells, check the antenna feed problem of the target cell. In the embodiment of the present invention, after determining the M1 first related cells that are most related to the target cell in terms of physical location and the M2 second related cells that are actually most related to the target cell, it can be determined whether the target cell has a network coverage anomaly problem according to the correlation between each first related cell and each second related cell.

[0028] In some embodiments, step 101 uses the Monte Carlo algorithm to simulate and calculate the overlapping coverage area between the target cell and any adjacent cell (referred to as adjacent cell b), which may include: (1) simulating the coverage area of ​​the target cell as a first simulated sector according to the cell coverage parameters of the target cell, and randomly determining X1 reference points in the first simulated sector. (2) simulating the coverage area of ​​adjacent cell b as a second simulated sector according to the cell coverage parameters of adjacent cell b, and randomly determining X2 reference points in the second simulated sector. (3) Determining the number of reference points X1 of the first simulated sector that belong to the second simulated sector. 12 , and the number of reference points X belonging to the first simulation sector among the X2 reference points of the second simulation sector 21 According to the determined X 12 and X 21 , determine the overlapping coverage area between the target cell and the adjacent cell b. The calculation method of the overlapping coverage area between the target cell and other adjacent cells can refer to the calculation method of the overlapping coverage area between the target cell and the adjacent cell b, which will not be repeated here.

[0029] In the above (1), simulating the coverage area of ​​the target cell as a first simulated sector may include: determining the first simulated sector corresponding to the target cell according to the cell location coordinates, cell coverage radius and cell lobe width of the target cell. Figure 2 As shown, the first simulated sector corresponding to the target cell can be represented by sector a, and the area of ​​sector a is Among them, θ a is the lobe width of the target cell, and r0 is the coverage radius of the target cell.

[0030] Optionally, X1 reference points may be randomly selected in sector a, and all reference points in sector a satisfy sector condition a, wherein sector condition a may be determined based on the location coordinates, coverage radius, beam width, and reference point direction angle of the target cell. In some embodiments, sector condition a may be:

[0031]

[0032] Among them, (x0, y0) are the coordinates of the center point of sector a, which can be determined according to the coordinate position of the target cell. (x, y) are the coordinates of any reference point in sector a. α is the angle between the vector composed of any reference point in sector a and (x0, y0) and the positive direction of the x-axis, which is also called the reference point direction angle in the embodiment of the present invention. The positive direction of the x-axis is the positive direction of the x-axis of the coordinate system where sector a is located. Specifically, when α≤180°, α=arccos((y-y0) / r0). When α>180°, α=360-arccos((y-y0) / r0).

[0033] In the above (2), any neighboring cell of the target cell, such as the coverage area of ​​neighboring cell b, can be simulated as a second simulated sector. Specifically, the second simulated sector corresponding to neighboring cell b can be determined according to the cell location coordinates, cell coverage radius and cell lobe width of neighboring cell b.

[0034] like Figure 2 As shown, the second simulated sector corresponding to the adjacent cell b can be represented by sector b, and the area of ​​sector b is Among them, θ b is the beam width of the adjacent cell b, and r1 is the coverage radius of the adjacent cell b.

[0035] Optionally, X2 reference points may be randomly selected in sector b, and all reference points in sector b satisfy sector condition b, which may be determined based on the position coordinates, coverage radius, beam width, and reference point direction angle of the adjacent cell b. In some embodiments, sector condition b may be:

[0036]

[0037] Among them, (x1, y1) are the coordinates of the center point of sector b, which can be determined based on the coordinate position of the adjacent cell b. (x, y) are the coordinates of any reference point in sector b. β is the angle between the vector composed of any reference point in sector b and (x1, y1) and the positive direction of the x-axis. Optionally, sector b and sector a are in the same coordinate system, and the positive direction of the x-axis is the positive direction of the x-axis of the coordinate system where sector a is located. Specifically, when β≤180°, β=arccos((y-y1) / r1). When β>180°, β=360-arccos((y-y1) / r1).

[0038] In the above (3), the reference point belonging to the second simulated sector among the X1 reference points of the first simulated sector is: a reference point that satisfies the sector condition of the second simulated sector. For example, reference point A is one of the X1 reference points, and reference point A satisfies the sector condition of sector b, then reference point A is a reference point belonging to the second simulated sector among the X1 reference points of sector a. In the embodiment of the present invention, the number of reference points belonging to sector b among the X1 reference points of sector a is recorded as X. 12 Similarly, the reference point belonging to the first simulated sector among the X2 reference points of the second simulated sector is: a reference point that satisfies the sector condition of the first simulated sector. For example, if reference point B is one of the X2 reference points and reference point B satisfies the sector condition of sector a, then reference point B is a reference point belonging to the first simulated sector in the second simulated sector. In the embodiment of the present invention, the number of reference points belonging to sector a among the X2 reference points of sector b is recorded as X. 21 .

[0039] According to the determined X 12 and X 21 , determine the overlapping coverage area between the target cell and the adjacent cell b, including: according to the formula (X 12 / X1*sector area a+X 21 / X2*sector area b) / 2, determine the overlapping coverage area between the target cell and the adjacent cell b.

[0040] The sector area a represents the sector area of ​​the first simulated sector corresponding to the target cell, and the sector area b represents the sector area of ​​the second simulated sector corresponding to the adjacent cell b.

[0041] By adopting the above method of calculating the overlapping coverage area between the target cell and the adjacent cell b, the N overlapping coverage areas between the target cell and the N adjacent cells can be calculated. Then, the M1 adjacent cells with the largest overlapping coverage area can be determined as the first related cells of the target cell. And, according to the measurement report of the target cell, the M2 second related cells that are actually closest to the target cell can be obtained. Optionally, M2 can be equal to M1.

[0042] Afterwards, according to the correlation between the M1 first related cells and the M2 second related cells, the antenna feed problem of the target cell is checked, which can be: according to the sampling points of the M1 first related cells and the sampling points of the M2 second related cells, the correlation coefficient k is calculated; according to the correlation coefficient k, the antenna feed problem of the target cell is checked. Optionally, the sampling points of each cell can be obtained by road testing.

[0043] Optional, correlation coefficient The M1 first related cells and the M2 second related cells are all cells of the base station where the non-target cell is located.

[0044] In the above method, the smaller the k value is, the greater the coverage anomaly problem of the antenna feed of the target cell is. Through this method, all cells in the existing network can be used as target cells to calculate the k value, and the k value threshold can be set. When the k value is lower than the set threshold, it means that there is a network coverage anomaly problem. Optionally, the k value threshold can be determined as 0.2. If the k value corresponding to the target cell is less than 0.2, the target cell may have coverage anomaly, and further determine whether it is an azimuth problem, cross-area coverage, or longitude and latitude problem.

[0045] In a specific example, the Monte Carlo algorithm is used to determine that the six cells with the highest physical correlation of a cell A are CELL1, CELL2, CELL3...CELL6, and the cumulative sampling points of the six cells are 12101. According to the measurement report of cell A, the six cells with the highest actual correlation of cell A are CELLA, CELLB...CELLF. The six cells with the highest physical correlation and the six cells with the highest actual correlation are different. The cumulative sampling points of the six cells with the highest actual correlation are 141020. The calculated k value is 12101 / 141020, which is less than 10%. It is suspected that there is a problem with the antenna feed direction angle of cell A, or there is a problem with the latitude and longitude engineering parameter data of the cell.

[0046] In the embodiment of the present invention, the overlapping coverage area of ​​the target cell and the adjacent cell is calculated based on the Monte Carlo algorithm, thereby determining the adjacent cell with the highest physical correlation with the target cell. In this way, the difficulty of calculation can be reduced to a large extent. Furthermore, in the embodiment of the present invention, the cell with abnormal antenna coverage is determined based on the sampling point ratio of the M1 cells with the highest physical correlation and the M2 cells with the highest actual correlation. The smaller the k value, the greater the probability that the antenna feeder has abnormal coverage.
