对于步骤S702至步骤S712涉及到的过程下面将进行详细说明；The process involved in steps S702 to S712 will be described in detail below;
首先，以小区为单位数据处理：(1)计算每个小区的平均RIP值，按照每个小区的100个RB的RIP做平均，得到AvgRIP；First, data processing is performed in units of cells: (1) calculating an average RIP value of each cell, and averaging RIPs of 100 RBs of each cell to obtain AvgRIP;
(2)对每个小区的每个RB的RIP与该小区的RIP均值进行比较，得到100个RB与均值的差值(RB1Diff～RB100Diff)。(2) Comparing the RIP of each RB of each cell with the RIP mean of the cell, and obtaining a difference between 100 RBs and the mean (RB1Diff to RB100Diff).
(3)从RB1Diff到RB100Diff中，分别计算RBDiff大于0的所有RB的均值，以及RBDiff小于0的所有RB的均值，然后用前面均值减去后面均值，记为RBAvgDiff；(3) From RB1Diff to RB100Diff, calculate the mean of all RBs with RBDiff greater than 0, and the mean of all RBs with RBDiff less than 0, and then subtract the following mean from the previous mean, denoted as RBAvgDiff;
(4)如果RBAvgDiff大于5，说明有部分RB的干扰比较高，将此小区记为有干扰的小区，其中，RBAvgDiff大于5是本可选实施例的举例说明，并不构成对本可选实施例中其他方式的限定；(4) If the RBAvgDiff is greater than 5, the interference of some RBs is relatively high, and the cell is recorded as a cell with interference. The RBAvgDiff is greater than 5 is an example of the optional embodiment, and does not constitute an optional embodiment. Qualification of other means;
(5)判断RB中哪些RB是连续RB：将RBDiff大于5的所有RB以RBID从小到大排序，然后用第二个RB的ID减第一个RB的ID，判断是否为1，是则第一个RBID为连续RB的起始ID，以此循环处理，直到第N个RB的ID减第N-1个RB的ID不等于1，则第N-1个RB的ID为连续RB的结束ID，然后得到连续RB的个数，当个数大于等于2时，这段RB为连续RB，否则从第N+1个RB重新计算起始RBID的位置；(5) Determine which RBs in the RB are consecutive RBs: Sort all RBs whose RBDiff is greater than 5 by RBID from small to large, and then use the ID of the second RB to subtract the ID of the first RB to determine whether it is 1, or not An RBID is the start ID of consecutive RBs, and is cyclically processed until the ID of the Nth RB minus the ID of the N-1th RB is not equal to 1, and the ID of the N-1th RB is the end of consecutive RBs. ID, and then the number of consecutive RBs. When the number is greater than or equal to 2, the RB is a continuous RB, otherwise the position of the starting RBID is recalculated from the (N+1)th RB;
(6)如果RBAvgDiff小于等于5，判断AvgRIP是否大于100dBm，若是则将此小区的全带宽(1～N RB)号记录为干扰RB位置；(6) If the RBAvgDiff is less than or equal to 5, determine whether the AvgRIP is greater than 100 dBm, and if so, record the full bandwidth (1 to N RB) number of the cell as the interference RB location;
(7)记录这些连续RB的RIP均值，并记录连续RB的编号，便于后续与周边小区进行比较。注意一个小区有可能有好几段连续RB，每段连续RB都要记录一个RIP均值和RB编号。(7) Record the RIP mean of these consecutive RBs, and record the number of consecutive RBs for subsequent comparison with neighboring cells. Note that a cell may have several consecutive RBs, and each RB shall record a RIP mean and RB number.
其次，查找干扰组：在所有小区中按照连续RB的RIP均值最高的小区从大到小排列。如果一个小区有多段连续RB，那么该小区排多次，以连续RB的起始中心频率+RB个数为索引。Secondly, the interference group is searched: in all cells, the cells with the highest RIP average value of consecutive RBs are arranged from large to small. If a cell has multiple consecutive RBs, the cell is ranked multiple times, and the starting center frequency + RB number of consecutive RBs is indexed.
连续RB的起始中心频点计算：读取网管无线参数表中的中心频率earfcnul，bandwidthul分别得到绝对频率和上行带宽，然后按照一个RB 180k进行转换，将每个RBID转换为绝对频率，具体算法如表1：The calculation of the starting center frequency of consecutive RBs: reading the central frequency earfcnul in the wireless parameter table of the network management, the bandwidth is respectively obtained the absolute frequency and the uplink bandwidth, and then converting according to one RB 180k, converting each RBID into an absolute frequency, the specific algorithm As shown in Table 1:

(2)在找到的同频小区中依次与主小区的连续RB编号进行对比，只要有一段连续的RB编号相同，则将这些小区记录下来；(2) comparing successive RB numbers of the primary cell in the found intra-frequency cell, and recording the cells as long as there are consecutive RB numbers being the same;
(3)对(2)中找到的所有小区，根据RIP均值从高到低，并取出与主小区非共站的最多6个(可设置)RIP均值最高的小区(不含主小区)。6个小区RIP均值都要小于主小区的RIP均值，若大于则不处理此干扰组，进行下一个循环；(3) For all cells found in (2), according to the RIP mean value from high to low, and take out up to 6 (settable) cells with the highest RIP mean value (excluding the primary cell) that are non-co-located with the primary cell. The average RIP of the six cells is smaller than the RIP average of the primary cell. If it is greater than the interference group, the interference group is not processed, and the next cycle is performed;
(4)得到6个小区的连续RB的RIP均值，若不足N个则结束，进行下一个循环；(4) Obtaining RIP average values of consecutive RBs of 6 cells, and if less than N, ending, proceeding to the next cycle;
再次，干扰源定位：Again, the interference source is located:
(1)从工参中确定6个小区的最大经度，最大纬度，最小经度和最小纬度，形成一个矩形，然后在矩形内分割为50*50栅格的经纬度集合，每个栅格都取该栅格中心点位置的经纬度，形成Point1～Pointn的集合；(1) Determine the maximum longitude, maximum latitude, minimum longitude and minimum latitude of the six cells from the industrial parameters, form a rectangle, and then divide into a 50*50 grid latitude and longitude set in the rectangle, each grid takes the The latitude and longitude of the position of the center point of the grid forms a set of Point1~Pointn;
(2)取出6个小区的RIP值，得到RIP1～RIP6；(2) taking out the RIP values of the six cells to obtain RIP1 to RIP6;
(3)取出经纬度集合中的第一个经纬度，记为Point1，计算出该点的位置和6个小区的距离，并转换为公里的单位，分别以D1～D6表示；(3) Take out the first latitude and longitude in the latitude and longitude set, and record it as Point1, calculate the position of the point and the distance between the six cells, and convert them into units of kilometers, which are respectively represented by D1 to D6;
(4)在工参中取出6个小区的天线高度H1～H6，单位为米；(4) Take out the antenna heights H1 to H6 of the six cells in the industrial reference, the unit is meters;
(5)在工参中分别计算该点与6个小区所在站点的方位角(即起始点为小区，该点为假设的天线法线方向，得到一个方位角，方位角正北为0，顺时针逐渐增加)，得到Azimuth1～Azimuth6。(5) Calculate the azimuth of the point and the site where the 6 cells are located in the industrial reference (that is, the starting point is the cell, the point is the assumed antenna normal direction, and an azimuth is obtained, and the azimuth is 0, smooth The hour hand is gradually increased), and Azimuth1 to Azimuth6 are obtained.
(6)分别用Azimuth1～Azimuth6减去每个小区的方位角，如果结果小于0则加上360，得到Azimuth1’～Azimuth6’。(6) The azimuth angle of each cell is subtracted from Azimuth1 to Azimuth6, respectively. If the result is less than 0, 360 is added to obtain Azimuth1'~Azimuth6'.
(7)将Azimuth1’～Azimuth6’分别代入到天线损耗数据文件中的HorizontalDegree，计算出HorizontalLoss1～HorizontalLoss6。(7) Calculate HorizontalLoss1 to HorizontalLoss6 by substituting Azimuth1' to Azimuth6' into HorizontalDegree in the antenna loss data file.
(8)根据以上已经得到的信息，分别计算每个小区的pathloss：(8) Calculate the pathloss of each cell based on the information obtained above:
pathloss＝-RIP-44.9*log(D)-13.82*Log(H)-6.55*Log(H)*Log(D)-HorizontalLoss，这样每个点得到6个pathloss的值，分别为pathloss1～pathloss6。Pathloss=-RIP-44.9*log(D)-13.82*Log(H)-6.55*Log(H)*Log(D)-HorizontalLoss, so that each point gets 6 pathloss values, pathloss1~pathloss6.
计算(pathloss1，pathloss2，pathloss3，pathloss4，pathloss5，pathloss6)的均方差，记为第一个点的StandDev1，以此方法循环得到所有点的StandDev；Calculate the mean square error of (pathloss1, pathloss2, pathloss3, pathloss4, pathloss5, pathloss6), record it as the first point of StandDev1, and use this method to get the StandDev of all points;
(9)取StandDev最小的那个点，做为疑似干扰位置； (9) Take the smallest point of StandDev as a suspected interference location;
(10)当干扰点位置到主小区的距离大于1000米(可设置)，忽略此条干扰记录；当干扰点位置到辅助定位小区的距离大于1000米，则忽略此辅助小区；(10) When the distance from the interference point location to the primary cell is greater than 1000 meters (settable), the interference record is ignored; when the distance from the interference point location to the auxiliary positioning cell is greater than 1000 meters, the secondary cell is ignored;
(11)得到所有小区的干扰位置数据，最后结果可能会有重复的情况，因为一个干扰源会干扰多个小区，因此最后结果，对于同一个3公里以内的相同的连续干扰RB，只显示一行记录。干扰结果展示如表2：(11) Obtain the interference location data of all cells, and the final result may be repeated, because one interference source may interfere with multiple cells, so the final result shows only one row for the same continuous interference RB within the same 3 km. recording.
