The transmission power information includes the target transmission power of the target base station corresponding to a plurality of coverage sub-areas.

[0075] Optionally, the target processing system can determine N different sampling points from the positions of the plurality of user terminals according to the position information of the plurality of user terminals in the first wireless network data set. For example, in the process of selecting the sampling points, because the weaker the level (i.e. signal receiving power) received by the user terminal is, the more dispersed it is, the positions of all user terminals of the target base station whose level is greater than -80dbm or above can be selected as candidate sampling points to enhance the sample quality. After the candidate sampling points are determined, the distances between all candidate sampling points whose receiving level is greater than -80dbm can be calculated, and N candidate sampling points with the largest distance between them can be selected as the sampling points to avoid the sampling points from gathering in a region. Wherein, the aforementioned N can be 3.

[0076] After the N sampling points are determined, for each sampling point, the target processing system can determine the target transmission power of the coverage sub-region corresponding to the sampling point according to the base station information, determine the receiving level value of the sampling point according to the signal quality information of the user terminal to which the sampling point belongs, and thus determine the signal attenuation value according to the receiving level value and the target transmission power of the coverage sub-region, and further back-calculate the distance between the sampling point and the target base station according to the signal attenuation value and the signal path loss relationship.

[0077] Optionally, after the distances between the N sampling points and the target base station are determined, the target processing system can determine the initial position of the target base station according to the distances between the N sampling points and the target base station. For example, the distances between the N sampling points and the target base station and the position information of the N sampling points are input into a position prediction model, and the initial position of the target base station is output by the position prediction model. For another example, a three-point positioning algorithm or other methods that can be used for position evaluation are adopted to determine the initial position of the target base station according to the distances between the N sampling points and the target base station and the position information of the N sampling points.

[0078] It should be noted that because a single base station can involve multiple coverage sub-regions, by considering the coverage sub-region where the sampling point is located and determining the target transmission power of the coverage sub-region, the signal attenuation value of the network signal transmitted by the base station can be accurately determined, thereby improving the accuracy of determining the distance between the sampling point and the target base station, and further improving the accuracy of determining the initial position.

[0079] Optionally, in the method for determining the position of the base station, the target transmission power of the coverage sub-area corresponding to the sampling point is determined according to the base station information, and the distance between the sampling point and the target base station is determined according to the target transmission power, the signal quality information of the user terminal to which the sampling point belongs, and a signal path loss relationship.

[0080] Optionally, the signal level of the terminal is strongly related to the transmission power, frequency, bandwidth, and channel number of the cell (i.e., coverage sub-area), and the transmission power, frequency, bandwidth, and channel number of different cells can be different.

[0081] Optionally, the area information at least includes the network standard (e.g., 4G, 5G), the maximum signal transmission power, and the number of resource blocks (RB) of the bandwidth, and can further include the frequency band, duplex mode, frequency, bandwidth, transceiver mode, CRS (Cell Reference Signal) port number, etc., wherein a single RB includes 12 REs (Resource Element).

[0082] Table 1

[0083]

[0084] For another example, Table 2 shows part of the area information of different cells corresponding to different operators under the network standard of 5G.

[0085] Table 2

[0086]

[0087] Optionally, the base station information of the wireless network data corresponding to the sampling point includes the cell ID (i.e., area identifier) corresponding to the sampling point, and the target processing system is pre-provided with the area information corresponding to each cell, so that the target processing system can obtain the area information corresponding to the cell according to the cell ID. The cell IDs of different cells corresponding to the same operator are different, and the cell IDs of cells corresponding to different operators are also different, i.e., the cell ID is a unique identifier.

[0088] For LTE networks, terminals perform network selection and handover operations by measuring the power of REs with CRS reference signals. For 5G, terminals perform these operations by measuring the average value of REs in the SSB (Synchronization Signal Block). Therefore, user terminals measure the signal power of REs within a single bandwidth. This means that the power received by the user terminal (i.e., signal received power) and the power reported refer to the power of a single RE. The single RE power output by the cell is related to factors such as maximum transmit power, transmit / receive mode, and bandwidth. By obtaining information such as the cell's maximum transmit power, bandwidth, and transmit / receive mode, the RE-level transmit power of cells in different standards and frequency bands can be determined. The aforementioned RE-level transmit power is the cell's target transmit power.

[0089] For example, when the network standard of a cell is 4G, the target transmit power of a cell can be calculated as follows:

[0090]

[0091] in, Indicates the target transmission power of the cell. Indicates the maximum signal transmission power of the cell. This indicates the number of transmit antennas in the cell, corresponding to the transmit / receive mode. For example, if the transmit / receive mode is 2T4R, then... Take 2, Indicates the number of RBs on the cell bandwidth. To increase the power of the CRS pilot signal received by the terminal, it can be achieved by adjusting... The parameter setting shifts the power of the RE signal that does not contain the CRS signal to the RE that does contain the CRS signal. To improve power efficiency, it is generally set to 1.

[0092] For example, based on the above formula, the target transmit power of cells under different operators and frequency bands in 4G can be calculated as shown in Table 3:

[0093] Table 3

[0094]

[0095] Optionally, to minimize public overhead, the 5G protocol design eliminates the 4G CRS pilot channel. Therefore, when the network standard of a cell is 5G, the user terminal receives the RE power of the SSB. The target processing system can calculate the target transmit power of the cell using the following formula:

[0096]

[0097] For example, according to the above formula, the target transmission power of the cell under different operators and different frequency bands under 5G can be calculated as shown in Table 4:

[0098] Table 4

[0099]

[0100] Optionally, the signal quality information at least includes the reference information receiving power, and can further include a dynamic network type, a base station signal strength, a downlink signal-to-interference noise ratio, a reference information receiving quality, and a reference information receiving power of a nearby base station, wherein the aforementioned reference information receiving power is the signal receiving power of the user terminal to which the sampling point belongs.

[0101] Optionally, the signal path loss = CRS transmission power (i.e., target transmission power) - terminal receiving signal power, so that the road loss value (i.e., signal path loss value) corresponding to different level values can be calculated from the CRS transmission power and the terminal receiving level value of different frequency bands, so as to determine the distance between the base station and the user terminal according to the road loss value.

[0102] Optionally, the signal path loss relationship can be determined according to the signal frequency of the cell. For example, for a frequency below 1.5 GHz (i.e., low frequency), the signal path loss relationship is as follows:

[0103]

[0104] wherein, represents the signal path loss value, represents the carrier frequency, represents the height of the base station antenna, represents the distance between the sampling point and the target base station, represents the terrain attenuation factor, represents the target transmission power of the cell, represents the signal receiving power of the user terminal. The above formula is also called Okumura-Hata formula.

[0105] For example, for a frequency above 1.5 GHz (i.e., high frequency), the signal path loss relationship is as follows:

[0106]

[0107] wherein, is a preset correction factor, and the above formula is also called COST231-Hata model.

[0108] For example, according to the above formula, the distance value corresponding to different road loss values of different cells under 4G system can be calculated as shown in Table 5:

[0109] Table 5

[0110]

[0111] In an optional embodiment, the above signal path loss relationship formula can be used in both 4G and 5G systems.

[0112] In an optional embodiment, in order to further improve the accuracy of the determined distance, in the case of a 4G network system, the above signal path loss relationship formula is used, and in the case of a 5G network system, a 3D-Uma (3D Urban Macrocell) signal path loss relationship formula can be used, and therefore, details are not repeated here.

[0113] It should be noted that by the above method, the target transmission power of the coverage sub-area is accurately and specifically determined, and the signal reception power is effectively determined, thereby improving the accuracy of the determined distance between the sampling point and the target base station.

[0114] Optionally, in the method for determining the position of the base station provided in the embodiments of the present application, the wireless network data further includes terminal parameters of the user terminal, and wherein the distance between the sampling point and the target base station is determined according to the signal reception power, the target transmission power, and the signal path loss relationship formula, including: determining the terminal model of the user terminal to which the sampling point belongs from the terminal parameters in the first set of wireless network data; obtaining the signal correction parameter corresponding to the terminal model, wherein the signal correction parameter is used to correct the level error generated when the user terminal receives the network signal; and determining the distance between the sampling point and the target base station according to the signal reception power, the target transmission power, the signal correction parameter, and the signal path loss relationship formula.

[0115] Optionally, modem demodulation chips used by different models of user terminals have great differences, resulting in certain differences in the received signal levels (i.e., signal reception power) of different terminals. For example, the received signal levels of different models of terminals at the same time, in the same cell, and at the same location are tested, and the tests are performed in areas with high signal strength, medium signal strength, and low signal strength, respectively, and the test results are shown in Table 6:

[0116] Table 6

[0117]

[0118] Therefore, the operation and maintenance personnel can determine the signal correction parameters corresponding to different terminal models according to the test results. For example, taking the user terminal of model a as the reference value, then for the user terminal of model c in the above table, the corresponding signal correction parameter is +7dB.

[0119] Optionally, in actual application, the terminal parameter includes model information of the user terminal, the target processing system can determine the terminal model of the user terminal to which the sampling point belongs from the terminal parameter in the first wireless network data set, and then acquire the signal correction parameter corresponding to the terminal model, so as to determine the distance between the sampling point and the target base station in combination with the signal correction parameter.

[0120] For example, for a frequency below 1.5 GHz (i.e., low frequency), the distance is inversely calculated by using the following formula:

[0121]

[0122] wherein, represents the signal correction parameter.

[0123] For example, for a frequency above 1.5 GHz (i.e., high frequency), the distance is inversely calculated by using the following formula:

[0124]

[0125] It should be noted that, by identifying the user terminal model and applying the corresponding correction parameter, the signal measurement deviation caused by different terminal hardware characteristics can be effectively compensated, the conversion from the signal quality information to the base station distance prediction is more accurate, and the error in the distance prediction is reduced.

[0126] Optionally, in the method for determining the position of the base station provided in the embodiments of the present application, in the case where N is 3, the initial position of the target base station is determined according to the distances between the N sampling points and the target base station, comprising: for each sampling point, taking the position of the sampling point as the center and the distance between the sampling point and the target base station as the radius, a circular region corresponding to the sampling point is determined; based on the position relationship among the circular regions corresponding to the three sampling points, the initial position of the target base station is determined.

[0127] Optionally, in the case where N is 3, taking the longitude and latitude of the selected three points as the center, three circles are made according to the distances between the three sampling points and the base station. Figure 3 is a schematic diagram for determining the initial position according to the embodiments of the present application Figure 1 As shown in Figure 3 , if there is a common intersection point among the three circular regions (i.e., the case where any two circular regions intersect with each other), the center point of the intersection point of the three circular regions is taken as the initial position (i.e., the D point in Figure 3 ).

[0128] Optionally, Figure 4 is a schematic diagram for determining the initial position according to the embodiments of the present application Figure 2 As shown in Figure 4As shown, if only two of the three circular regions intersect, then the center point of the intersection of these two circular regions (i.e., ...) is taken. Figure 4 Point F in the diagram is used as the initial position.

[0129] Optional, Figure 5 This is a schematic diagram of determining the initial position according to the embodiments of this application. Figure 3 ,like Figure 5 As shown, if each of the three circular regions intersects with the others, but the three circular regions do not share a common intersection point, then a quadrilateral is constructed based on the intersection points of each of the three circular regions (e.g., ...). Figure 5 (in the quadrilateral DFEG), and take the center of the quadrilateral (i.e. Figure 5 Point H in the diagram is used as the initial position of the target base station.

[0130] Optional, Figure 6 This is a schematic diagram of determining the initial position according to the embodiments of this application. Figure 4 ,like Figure 6 As shown, if none of the three circular regions intersect, then a triangle is constructed based on the centers of the three circular regions (e.g., ...). Figure 6 In triangle ABC, the center of the incircle of the triangle (i.e., Figure 6 Point D in the diagram is determined as the initial location of the target base station.

[0131] It should be noted that the above method enables the determination of the initial location of the base station using mathematical calculations and geometric analysis, thereby improving the accuracy of determining the initial location.

[0132] Optionally, in the method for determining the location of a base station provided in this application embodiment, the network signal transmitted by the target base station corresponds to multiple coverage sub-regions. The method for determining the target location of the target base station based on the initial coverage range and the second wireless network dataset includes: determining the area range of multiple coverage sub-regions in the initial coverage range based on the initial coverage range and the second wireless network dataset; and determining the target location of the target base station based on the area range of the multiple coverage sub-regions.

[0133] Optionally, the target processing system can determine the initial coverage area of ​​the target base station based on the initial location of the target base station and according to the preset range width and range length. That is, the initial coverage area is a rectangle, and the center of the rectangle is the initial location.

[0134] After the initial coverage range is determined, the target processing system can determine the target position of the target base station in the initial coverage range according to the second wireless network data set. For example, according to the signal strengths received by each user terminal in the second wireless network data set, the position with the highest average received signal strength value is determined as the target position. For another example, the network signal transmitted by the target base station corresponds to a plurality of coverage sub-regions, and the target processing system can determine the region ranges of the coverage sub-regions in the initial coverage range according to the second wireless network data set, and thus determine the target position of the target base station according to the region ranges of the coverage sub-regions, such as determining the confluence of the coverage sub-regions as the target position of the target base station.

[0135] It should be noted that, since there is a certain correlation between the positions of the plurality of coverage sub-regions and the position of the target base station, the plurality of coverage sub-regions are divided from the initial coverage range according to the second wireless network data set, and the target position of the target base station is determined according to the region ranges of the plurality of coverage sub-regions, which can effectively improve the accuracy of determining the target position.

[0136] Optionally, in the method for determining the position of the base station provided in the embodiments of the present application, the region ranges of the plurality of coverage sub-regions in the initial coverage range are determined according to the initial coverage range and the second wireless network data set, including: performing rasterization processing on the initial coverage range to obtain a plurality of grids; for each grid, determining the corresponding wireless network data of the target base station in the grid from the second wireless network data set to obtain a third wireless network data set; determining the coverage sub-region to which the grid belongs according to the base station information in the third wireless network data set; and determining the region ranges of the plurality of coverage sub-regions in the initial coverage range according to the coverage sub-regions to which the grids belong.

[0137] Optionally, the target processing system can determine the initial coverage range of the target base station according to a preset range width and range length with the initial position of the target base station as the center, i.e., the initial coverage range is a rectangle with the initial position as the center. Then, rasterization processing is performed on the initial coverage range to obtain a plurality of grids, for example, the length and width of each grid are set to 20 m.

[0138] After the plurality of grids are determined, for each grid, the corresponding wireless network data of the target base station in the grid is determined from the second wireless network data set to obtain a third wireless network data set corresponding to the grid. For example, the geographical range corresponding to the grid is determined according to the position of the grid in the initial coverage range, and thus in the case that the position information in the wireless network data belongs to the geographical range, it is determined that the wireless network data belongs to the third wireless network data set corresponding to the grid, and otherwise, in the case that the position information in the wireless network data does not belong to the geographical range, it is determined that the wireless network data does not belong to the third wireless network data set corresponding to the grid.

[0139] Optionally, the target processing system can count the occurrence times of each cell ID in the third wireless network data set according to the base station information in the third wireless network data set, and determine the cell corresponding to the cell ID with the most occurrence times and the occurrence times not being 0 as the cell to which the grid belongs, that is, as the coverage sub-area to which the grid belongs. If the third wireless network data set corresponding to a grid is empty, it is determined that the grid does not belong to any cell. For example, Figure 7 is a schematic diagram of the initial coverage range provided by an embodiment of the present application Figure 1 , Figure 7 The average value of the user terminal receiving level in different grids in the initial coverage range is shown in FIG. 3. For example, red color indicates a place with a higher level value, green color indicates a place with a lower level value, and a blank place indicates that no user terminal receives the network signal output by the target base station.

[0140] Optionally, the target processing system can determine the area range of the plurality of coverage sub-areas in the initial coverage range according to the coverage sub-area to which each grid belongs, that is, determine the area range formed by the grids belonging to the same coverage sub-area as the area range of the coverage sub-area. For example, Figure 8 is a schematic diagram of the initial coverage range provided by an embodiment of the present application Figure 2 As shown in Figure 8 , the area ranges of different cells are marked with different colors in Figure 8 , Figure 8 grids with the same color in Figure 8 belong to the same cell, the area ranges of three cells are shown in

[0141] .

[0142] Optionally, in the method for determining the position of the base station provided by the embodiments of the present application, after determining the coverage sub-area to which the grid belongs according to the base station information in the third wireless network data set, the method further comprises: in the case that there is a first grid in the initial coverage range, deleting the corresponding relationship between the first grid and the coverage sub-area, wherein the first grid refers to a grid that is different from the initial coverage sub-area to which all the grids adjacent to the initial coverage sub-area belong; in the case that there is a second grid in the initial coverage range, determining the coverage sub-area to which the second grid belongs according to the coverage sub-area to which the grid adjacent to the second grid belongs, wherein the second grid refers to a grid that does not belong to any coverage sub-area; and in the case that there is a third grid in the initial coverage range, deleting the corresponding relationship between the third grid and the coverage sub-area, wherein the third grid refers to a grid in a non-maximum area block in the multiple non-connected area blocks corresponding to the same coverage sub-area in the initial coverage range.

[0143] In order to improve the accuracy of the area range of the determined coverage sub-area, after determining the coverage sub-area to which the grid belongs, the target processing system can further adjust the coverage sub-area to which each grid belongs. For example, the target processing system can perform the following steps:

[0144] (1) Isolated grid processing;

[0145] For example, Figure 9 is a schematic diagram of a first grid provided by the embodiments of the present application, Figure 9 The grid marked in red in FIG. 8 is an isolated grid, i.e., a first grid. In the case that there is an isolated grid, the isolated grid point is removed, i.e., the grid that is not the same as the grid adjacent to the target grid is removed. For example, Figure 9 the central grid belongs to the 1st cell, and the eight surrounding grids belong to the 2nd and 3rd cells or have no belonging information, then the central cell is marked as 0, i.e., there is no belonging cell, and the corresponding relationship between the isolated grid and the cell is deleted. After processing the coverage sub-area in the initial coverage range shown in FIG. 8 in this way, Figure 8 the coverage sub-area shown in FIG. 9 can be obtained. Figure 10

[0146] (2) Blank grid filling;

[0147] For example, Figure 11 is a schematic diagram of a second grid provided by the embodiments of the present application, Figure 11 The grid marked in red in FIG. 10 is a blank grid, i.e., a second grid, which is determined by Figure 10 ​It can be seen that the grid coverage of the cell is not continuous. Therefore, further processing is needed to fill the blank areas. The specific filling method is as follows: traverse all grids. If a blank grid is encountered, count the belonging cells of the 8 neighboring grids within a 3×3 grid centered on the blank grid (i.e., the first grid range). The belonging cell that appears most frequently among the 8 neighboring grids is taken as the belonging cell of the target blank grid. To avoid an isolated grid with a belonging cell filling all the surrounding blank grids, it is necessary to determine the coverage sub-region to which the grid belongs if more than half of the grids within the 3×3 grid are non-blank grids. Figure 11 The process determines that the grid belongs to cell 2. If there is no result within the 3×3 grid, the size is increased to a 5×5 grid (i.e., the second grid range) and then up to a 7×7 grid (i.e., the third grid range). If half or more of the grids within the 7×7 grid are still blank, then the second grid is determined not to belong to any coverage sub-region, and the coverage sub-region to which the second grid belongs is uncertain. This method is followed for... Figure 10 After processing the coverage sub-regions within the initial coverage area shown, the following can be obtained: Figure 12 The covered sub-region is shown.

[0148] (3) Posterior lobe elimination;

[0149] like Figure 12 As shown, the back lobe coverage of the cell is very obvious, especially... Figure 12 In a red-colored cell, the back lobe generally has a smaller coverage area than the front lobe, and its voltage level is lower than that of nearby grid cells on the front lobe. Optionally, connected grid cells can be defined as a block (i.e., a region block). Figure 13 This is a schematic diagram of the covered sub-region provided according to an embodiment of this application. Figure 13 The blue-highlighted grid cells on the left indicate that they belong to the same covered sub-region, such as... Figure 13 As shown, if connected grid cells are defined as a block, then Figure 13 The covered sub-region shown in the figure can be divided as follows: Figure 13 The three regions shown in the right-hand image are as follows.

[0150] In an alternative embodiment, when the covered sub-region includes multiple area blocks, only the block with the largest area is retained (e.g., Figure 13 The largest block in the middle is block 2), which means deleting the correspondence between the grids in other blocks (i.e., the third grid) and the cells, and turning the grids in other blocks into blank grids.

[0151] Optionally, in the case that the plurality of area blocks are included in the coverage sub-area, the block with the largest area and the block with the highest average signal receiving power are reserved, and the average signal receiving power of a certain area block is calculated according to the average signal receiving power in the target wireless network data corresponding to the area block, wherein the target wireless network data refers to the wireless network data of the same coverage sub-area as the area block.

[0152] In an optional embodiment, the first grid in the initial coverage sub-area is processed first, then the second grid is processed, and then the third grid is processed. Optionally, after the third grid is processed, a blank filling is performed again, that is, the second grid in the initial coverage sub-area is processed again, so as to obtain the final coverage sub-area to which each grid in the initial coverage sub-area belongs. For example, after the above operations, the initial coverage range shown in FIG. 6 is obtained. Figure 14

[0153] It should be noted that, by deleting the correspondence between the isolated grid and the coverage sub-area, the boundary effect and the interference of the isolated signal point on the signal analysis are avoided, and the continuity of the signal coverage is ensured. By filling the blank grid, it is ensured that all geographical areas are reasonably classified, and data omission is avoided. By eliminating the correspondence between the grids in the non-continuous area block, the geographical continuity of the coverage sub-area can be effectively improved, so that the accuracy of the area range of the finally determined coverage sub-area can be effectively improved.

[0154] Optionally, in the method for determining the position of the base station provided in the embodiments of the present application, the target position of the target base station is determined according to the area range of the plurality of coverage sub-areas, comprising: performing traversal processing on the grids in the initial coverage range based on a preset grid window size, to determine whether there is a target grid area in the initial coverage range, wherein the target grid area refers to the area corresponding to the grid window associated with the plurality of coverage sub-areas; and in the case that there is a target grid area, determining the target position of the target base station based on the center position of the target grid area.

[0155] Optionally, the preset grid window size can be 3x3. For example, the target processing system can traverse all 3x3 grid blocks in the initial coverage range, and if the 3x3 grid block contains the grids of all cells in the initial coverage sub-area, it is considered that the 3x3 grid block is a target grid area, and the center position of the target grid area is a station site possible position. For example, Figure 15 is a schematic diagram of the target grid area according to the embodiments of the present application, Figure 15 The grid window shown in FIG. 6 contains all the grids of the cells in the initial coverage sub-area, that is, the grid window is associated with all the coverage sub-areas in the initial coverage sub-area, so the area of the grid window is determined as the target grid area, and the center position of the target grid area is determined as the target position of the target base station. Figure 15 ​The position of the middle red grid is a possible position of the station site.

[0156] Optionally, if no possible position is found by traversing all 3x3 grids, the grid window size is enlarged to 5x5, and then to 7x7. If no possible position is found, it is determined that the target position of the base station cannot be determined. If a target grid area is found, the target position of the target base station is determined according to the center position of the target grid area, for example, by performing an arithmetic average calculation, or for example, by selecting the center position of any one of the target grid areas as the target position of the target base station.

[0157] Optionally, as shown in FIG. 6, the initial position in the initial position of the target base station is determined according to the position of the base station in the initial position of the target base station. Figure 14 Figure 14 The possible position of the station site in the possible position of the station site is equivalent to the center position of the target grid area. Figure 14 The predicted position in the predicted position of the target base station is the target position of the target base station. Figure 14 The true position in the true position of the target base station is a position measured by manual measurement, that is, the error between the target position determined according to the method provided in the present application and the true position of the target base station is small, thereby effectively improving the accuracy and efficiency of the determination of the base station position. Figure 14

[0158] As can be seen, in the present embodiment, the purpose of automatically determining the base station position according to the wireless network data is achieved, and the technical effect of improving the efficiency of determining the base station position is achieved, thereby solving the technical problem of low efficiency of determining the base station position caused by relying on manual detection of the base station position in the related art.

[0159] It should be noted that the steps shown in the flowchart of the accompanying drawings can be executed in a computer system such as a set of computer executable instructions, and although a logical order is shown in the flowchart, in some cases, the steps shown or described herein can be executed in an order different from that shown herein.
