Embodiments of the present application provide a method and device for judging the consistency of cell antenna feeder coverage, which can be applied to the scenario shown in FIG. 1 . FIG. 1 is a schematic diagram of inter-frequency handover between adjacent base stations. In the figure, each base station includes three A sector cell, the base station covers cells with different frequencies in the same sector, the solid line and the dashed line represent the coverage of different frequencies. Ideally, the sectors of the two frequencies completely overlap. The handover process of cells with different frequency points between neighboring base stations. The purpose of this application is to determine the coverage consistency of the different frequency sectors of the base station by studying the number of times and signal strength after the inter-frequency signaling of the base station is cut out.

An embodiment of the present application provides a method for judging the consistency of cell antenna feeder coverage. As shown in FIG. 2 , the method may include S101-S103:

S101. Acquire inter-frequency handover information of cells including at least two different frequency points within a preset time period.

First, the grids are divided and numbered according to the latitude and longitude within the coverage of the base stations of the whole network. The grid refers to the rectangular area formed by the latitude and longitude lines on the map within the coverage of the base stations of the whole network. The area of the grid is fixed and there is a unique number. Optionally, the grids covered by the cell to be analyzed are sorted and counted to obtain the total number of grids to be analyzed M.

Then, the signaling information in each grid of cells including at least two different frequency points within a preset time period is acquired. The preset time period can be defined manually. The longer the value is taken, the more comprehensive the statistical data results will be. more accurate. The signaling information refers to the interaction signaling reported by the UE to the base station in the LTE system. The signaling process within a preset time period is extracted from the signaling information, including information such as start time, end time, process type, and event name. Then eliminate the signaling records that do not meet the conditions. Specifically, the obtained signaling processes are sorted by time, and the signaling records of the same base station before and after the handover, that is, the same-site handover, are eliminated, so as to determine the inter-frequency handover information in the signaling information. make.

Finally, the inter-frequency handover information of cells including at least two different frequency points within a preset time period is obtained from the inter-frequency handover signaling, where the inter-frequency handover information includes the number of inter-frequency handover requests in each grid, the number of inter-frequency handover requests in each grid The number of times the signal strength is within the preset range before the intra-cell inter-frequency handover request is sent, and the total number of inter-frequency handover requests in all cells in the cell. Wherein, obtaining the number of inter-frequency handover requests in each grid of cells including at least two different frequency points within a preset time period is to count the signaling process of the current grid, and aggregate and count the number of times of initiating handover requests; Obtain the number of times that the signal strength is within the preset range before the inter-frequency handover request in each grid is sent, that is, count the signaling process of the current grid. The signal strength is extracted from the measurement report MeasurementReport, before the user initiates the handover request. The UE will report the signal strength of the cell at the current location at the current moment, and obtains the number of times that all the signal strengths of the cell are within the preset range before the handover out request is initiated by statistics.

S102. Calculate the coverage of each grid in the cell according to the inter-frequency handover information, and calculate the relative coverage of each grid according to the coverage to form a set.

After obtaining the inter-frequency handover information through step S101, it is also necessary to obtain a user-defined coverage index. The coverage index refers to an index parameter defined to measure whether the coverage directions of cells with different frequencies in the same sector of the base station are consistent. Including: raster and coverage relationship coefficient, coverage and relative coverage. The grid-coverage relationship coefficient is to measure the ratio of the total number of grid handover requests under the coverage of the cell to be analyzed to the number of handover requests of the cell to be analyzed; the coverage is the current grid within a preset time period when the UE sends a handover request The ratio of the record when the previous signal strength is within the preset range to the total signal strength record and the product of the grid and the coverage relationship coefficient; the relative coverage is the ratio of the grid coverage of two cells with different frequencies.

分别计算该小区中各栅格的覆盖度μ_ij，其中,N_ij为栅格内的异频切换请求次数、T_ij为各栅格内异频切换请求发出前信号强度在预设范围内的次数、S为所有栅格内异频总切换请求次数,i为小区频点编号，j为栅格编号。具体的，首先计算栅格同覆盖关系系数，即

该值越大表明该栅格在最终计算待分析小区的同覆盖度时显现的效果越明显，得到的关系系数越小，意味着当前栅格的可计算性也越小。然后将该系数与预设时间段内当前栅格在UE切换请求发出前信号强度在预设范围内时的记录次数T_ij所占总体信号强度记录次数S的比值

相乘得到各栅格的覆盖度μ_ij。然后再根据该覆盖度μ_ij确定各栅格的相对覆盖度以形成集合，具体的，获取小区中各栅格处于不同频点时的覆盖度μ_ij，从获取到的所有该覆盖度μ_ij中选择一个最大值以及一个最小值，计算所述最小值与所述最大值的比值得到各栅格的相对覆盖度，统计所有的栅格中的不同频点小区的相对覆盖度以形成集合。该相对覆盖度用于表示包括至少两个不同频点的小区在同一栅格内的覆盖度比值，取值范围为(0,1)。需要注意的，若当前栅格中只有两个频点小区中其中一个的覆盖记录，则此时直接记该相对覆盖度的值为0。Respectively calculating the coverage of each grid in the cell according to the inter-frequency handover information specifically includes: according to the formula

Calculate the coverage μ _ij of each grid in the cell, where N _ij is the number of inter-frequency handover requests in the grid, and T _ij is the signal strength within the preset range before the inter-frequency handover request in each grid is sent. times, S is the total number of inter-frequency handover requests in all grids, i is the cell frequency point number, and j is the grid number. Specifically, first calculate the grid-coverage relationship coefficient, that is,

The larger the value, the more obvious the effect of the grid in the final calculation of the same coverage of the cell to be analyzed, and the smaller the obtained relationship coefficient, which means that the computability of the current grid is also smaller. Then the coefficient is the ratio of the number of recording times T _ij to the total number of recording times S of signal strength when the signal strength of the current grid is within the preset range before the UE handover request is sent in the preset time period

Multiply to get the coverage μ _ij of each grid. Then, the relative coverage of each grid is determined according to the coverage μ _ij to form a set. Specifically, the coverage μ _{ij of each grid in the cell at different frequency points is obtained, and all the obtained coverage μ ij are} obtained Select a maximum value and a minimum value from among them, calculate the ratio of the minimum value to the maximum value to obtain the relative coverage of each grid, and count the relative coverage of cells with different frequency points in all grids to form a set. The relative coverage is used to represent the coverage ratio of cells including at least two different frequency points in the same grid, and the value range is (0, 1). It should be noted that if there is only a coverage record of one of the two frequency point cells in the current grid, then directly record the value of the relative coverage as 0 at this time.

S103: Determine whether the antenna feeder coverage of the cell is consistent according to the proportion of the relative coverage in the set that is higher than the first preset threshold.

In the set, calculate the proportion of the relative coverage higher than the first preset threshold, the first preset threshold is a threshold used to measure the relative coverage of the grid, and the value is (0, 1], the higher that this first preset threshold value is set, the more accurate the final judgment.Can determine whether the antenna feeder coverage of this community is consistent according to this ratio value.Optional, the judgment method includes: if in the set The larger the proportion of the relative coverage higher than the first preset threshold, the higher the coverage consistency of the cell antenna feeder in the cell. Or, if the relative coverage in the set is higher than the first preset threshold When the ratio value of the value exceeds the second preset threshold value, it is considered that the antenna feeder coverage of the cell is consistent. The larger the ratio value is, the larger the ratio value is, it is explained that the position of the cell with different frequency points in the same sector is located before the handover request is sent. The closer the signal strength range is, the more grids there are, which means that the coverage of the two cells is basically the same at this time; if the ratio is closer to 0, it means that the two cells are in the signal strength range before the handover request is sent. The fewer the same grids, it means that the coverage at this time is inconsistent, wherein the second preset threshold value can be set according to the analysis precision requirement.

The present invention provides a method and device for judging the consistency of cell antenna feeder coverage. First, the number of inter-frequency handover requests within a preset time period and the number of times that the signal strength of each grid is within a preset range before the inter-frequency handover request is sent are obtained. And the total number of inter-frequency handover requests in all grids, then calculate the coverage of each grid in the cell according to the formula, determine the relative coverage of each grid according to the coverage to form a set W, and finally pass through the set W in the The relative coverage is higher than the proportion of the first preset threshold value. It can be known that the number of grids where the signal strength range of the location of the cell with different frequency points in the same sector is close to the signal strength range before the handover request is sent, so as to determine the cell's signal strength range. Whether the antenna and feeder coverage is consistent. It can automatically judge whether the antenna feeder coverage of the expansion cell is consistent, which can not only save, material and financial resources, but also work efficiency.
