[0038] In the embodiments of the present application, the term "and / or" describes the association relationship of the associated objects, indicating that three relationships may exist. For example, A and / or B may represent: A exists alone, A and B exist at the same time, and B exists alone. The character " / " generally indicates that the associated objects before and after are in an "or" relationship.

[0039] In the embodiments of the present application, the term "plurality" refers to two or more than two, and other quantifiers are similar.

[0040] The following will be combined with the drawings in the embodiments of the present application to clearly and completely describe the technical solutions in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

[0041] The basic working parameters of base stations are relatively static, with few adjustments and modifications. They contain relatively complete information and can be used as basic data for analysis. This can be used to analyze the location and angle of the base station, thereby reflecting whether the location setting of the base station is reasonable, whether the angle setting is abnormal, and other issues. Further analysis and optimization can be carried out to improve the utilization rate of the base station and optimize the base station construction plan.

[0042] In view of the problems in the prior art that the base station optimization selection range is relatively small, the time taken is relatively long, and there is no timely and rapid response, the embodiments of the present application provide a solution by collecting basic information of the base station, constructing a polygon based on information such as the azimuth angle and downtilt angle of the base station to approximate the signal coverage range of the base station, and making an overlap judgment with the signal coverage range of the surrounding base stations to determine whether there is an overlapping area, the size of the overlapping area, and the proportion of the overlapping area, so as to adjust the working parameters of the base station and optimize the base station angle setting and base station distribution, so that the base station has a better signal switching band and the base station area setting is more reasonable and efficient.

[0043] Figure 1 A flow chart of a method for adjusting base station working parameters provided in an embodiment of the present application is shown as follows: Figure 1 As shown, the method comprises the following steps:

[0044] Step 100: Obtain initial working parameter information corresponding to each base station;

[0045] Specifically, in an embodiment of the present application, in order to use the engineering parameter information of the base station to optimize the base station site, it is first necessary to obtain the initial engineering parameter information of all base stations within the area to be optimized, such as the initial position latitude and longitude coordinates, initial direction angle, initial downtilt angle and initial antenna height of the base station.

[0046] The area to be optimized may be any area where base station site optimization is required, and its area range is not specifically limited. For example, it may be the urban area of ​​Shanghai or the Haidian District of Beijing.

[0047] Step 101: Determine a polygon corresponding to each base station and used to represent the coverage range of the base station signal based on initial working parameter information;

[0048] Specifically, after obtaining the initial engineering parameter information corresponding to each base station, a polygon corresponding to each base station for characterizing the base station signal coverage range can be generated according to the location longitude and latitude coordinates, azimuth angle, downtilt angle, antenna height and other data of the base station in the initial engineering parameter information. It should be noted that the number of sides and shape of the polygon are not specifically limited, for example, it can be a pentagon, a regular pentagon, a hexagon or a regular hexagon.

[0049] Step 102: Based on a preset model, adjust the geometric parameters of the polygons corresponding to each base station so that the overlapping area of ​​two adjacent polygons meets a preset condition;

[0050] Specifically, after obtaining the initial engineering parameter information of each base station and generating polygons corresponding to each base station for characterizing the base station signal coverage range based on the initial engineering parameter information, the geometric parameters of each polygon (such as the vertex coordinates, center point coordinates or side length of the polygon, etc.) can be input into a pre-trained model to adjust the geometric parameters of the polygons corresponding to each base station so that the overlapping area between every two adjacent polygons can meet the preset conditions.

[0051] The preset condition may be that the overlapping area of ​​two adjacent polygons is smaller than a preset area value, or that the overlapping area ratio of two adjacent polygons is smaller than a preset threshold value.

[0052] It should be noted that the overlapping area ratio refers to the ratio of the overlapping area of ​​two adjacent polygons to the area of ​​any one of the polygons. For example, the areas of two adjacent polygons are s1 and s2 respectively, and their overlapping area is s3. Then their overlapping area ratio includes two values ​​s3 / s1 and s3 / s2. If the maximum value of s3 / s1 and s3 / s2 is less than the preset threshold value, it is determined that the overlapping area ratio of the two adjacent polygons is less than the preset threshold value, that is, the overlapping area of ​​the two adjacent polygons meets the preset conditions.

[0053] The above-mentioned preset area value and preset threshold value can be set according to actual needs or engineering design experience, and are not specifically limited. For example, the preset threshold value can be 30%.

[0054] Step 103: Based on the adjusted geometric parameters of the polygons corresponding to the base stations, the target engineering parameter information corresponding to the base stations is determined, and the initial engineering parameter information is updated and adjusted.

[0055] Specifically, after adjusting the geometric parameters of the polygons corresponding to each base station using a pre-trained model, the target engineering parameter information corresponding to each base station can be derived based on the adjusted geometric parameters of the polygons corresponding to each base station. The target engineering parameter information can be used to update and adjust the initial engineering parameter information of the base station, thereby achieving optimization of the base station site.

[0056] For example, the initial working parameter information includes an initial downtilt angle. After adjusting the geometric parameters of the polygons corresponding to each base station using a pre-trained model, the target downtilt angle corresponding to each base station can be derived based on the adjusted geometric parameters of the polygons corresponding to each base station, thereby updating and adjusting the initial downtilt angle of the base station according to the target downtilt angle. After the downtilt angle of the base station is adjusted to the target downtilt angle, it can have a smaller signal coverage overlap area with other adjacent base stations, thereby achieving optimization of the base station site.

[0057] The above-mentioned target engineering parameter information may include the target position latitude and longitude coordinates of the base station, the target direction angle, the target downtilt angle and the target antenna hanging height.

[0058] The method for adjusting the working parameters of base stations provided in the embodiment of the present application generates polygons corresponding to each base station for characterizing the signal coverage range of the base station based on the initial working parameter information of the base station, optimizes and adjusts the geometric parameters of the polygons corresponding to each base station using a preset model, and derives the target working parameter information corresponding to each base station based on the adjusted geometric parameters of the polygons corresponding to each base station, thereby updating and adjusting the initial working parameter information of the base station, being able to quickly give suggestions for optimizing site distribution, reduce labor costs, and perform large-scale site distribution optimization.

[0059] The following uses two adjacent base stations as an example to illustrate some steps in the above method.

[0060] Figure 2 A schematic diagram of the coverage area of ​​two adjacent base stations provided in an embodiment of the present application, such as Figure 2 As shown, the two adjacent base stations are base station A 200 and base station B 210. The antenna heights and total downtilt angles of the two base stations can be obtained according to the initial engineering parameter information of the two base stations. Based on the antenna heights and total downtilt angles, the main lobe ray coverage distance d_a of the cell of base station A 200 and the main lobe ray coverage distance d_b of base station B 210 can be calculated using the formula |OB|=|OA| / tan(θ). In the formula, |OB| is the main lobe ray coverage distance of the cell of the base station, |OA| is the antenna height of the base station, and θ is the total downtilt angle of the base station.

[0061] After calculating the main lobe ray coverage distances d_a and d_b of the cells of base station A 200 and base station B 210, two regular hexagons with base station A 200 and base station B 210 as one of the vertices can be constructed based on the direction angle, base station location and other information in the initial engineering parameter information, as shown in FIG. Figure 2 As shown, the two regular hexagons are used to represent the signal coverage ranges of base station A 200 and base station B 210, that is, the cell coverage areas of base station A 200 and base station B 210, respectively.

[0062] The cell coverage area is a regular hexagon with a side length of a. The area calculation formula of the regular hexagon is:

[0063] The coverage area of ​​base station A 200 cell is:

[0064] The coverage area of ​​the base station B 210 cell is:

[0065] The area of ​​the coverage overlap region 220 is the overlapping area of ​​"the coverage area of ​​the cell of base station A 200" and "the coverage area of ​​the cell of base station B 210".

[0066] The following solution can be used to calculate the overlapping area, and the solution analysis is as follows.

[0067] Obviously, the intersection of convex polygons is still a convex polygon. The key to this solution is to first find all the vertices of the intersection convex polygons, and then use the area algorithm of convex polygons to solve it.

[0068] First, we need to clarify the vertex composition of the intersection convex polygon. In this problem, it is easy to prove that the vertices of the intersection convex polygon should come from the following two types of points:

[0069] (1) The vertices of two known polygons;

[0070] (2) The intersection of the sides of two polygons.

[0071] Method for finding the first type of point: Obviously, if a vertex of a polygon is inside another polygon (including on the edge), then the vertex is a vertex of the intersection convex polygon. Therefore, we only need to judge the vertices of the two polygons in turn to check whether they are contained in the other polygon to find the first type of point. This solution compares the sum of the areas of the triangles formed by the point to be judged and all the edges of the other polygon in order with the area of ​​the other polygon to determine the belonging of the point. If the sum of the areas of the triangles formed by the point and all the edges of the other polygon in order is greater than the area of ​​the other polygon, then the point is outside the other polygon and does not belong to the first type of point; otherwise, it is a vertex of the intersection convex polygon.

[0072] Method for finding the second type of points: When two polygons intersect, there may be two overlapping sides (including partial overlapping). Obviously, the overlapping part must be an edge of the intersecting convex polygon. The vertex of this edge is the vertex of the two known polygons, that is, it should belong to the first type of points. This type of vertex is obviously included in the method for finding the first type of points. Therefore, when we find the intersection of the edges of two polygons, we do not need to calculate the intersection when the two edges overlap, but only calculate the intersection when the two edges intersect (not parallel). In this solution, in order to find the intersection of two edges, we use the parametric equation representation of the line segment, that is:

[0073] x=a*t+b,

[0074] y=c*t+d, where 0≤t≤1;

[0075] In the formula, x, y represent the intersection vertex (x, y) of the polygonal line segment, b and d are the x and y coordinate values ​​of one of the endpoints 1 of the line segment, (a+b) and (c+d) are the x and y coordinate values ​​of the other endpoint 2 of the line segment, a is the difference between the x coordinate values ​​of endpoint 2 and endpoint 1 of the line segment, c is the difference between the y coordinate values ​​of endpoint 2 and endpoint 1 of the line segment, and t is the independent variable of the parametric equation.

[0076] Assume that the coordinates of the two endpoints of the line segment are (x0, y0) and (x1, y1), then the parametric equation of the line segment can be written as:

[0077] x=(x1-x0)*t+x0,

[0078] y=(y1-y0)*t+y0, where 0≤t≤1;

[0079] In the formula, x, y represent the intersection vertices (x, y) of the polygon segments, and t is the independent variable of the parametric equation.

[0080] Based on this, we can find the intersection point of two edges.

[0081] If the vertex of a polygon is on the edge of another polygon, the above algorithm shows that it will be counted as two types of points respectively. Therefore, some of the vertices of the intersection convex polygon we finally obtain may be repeated, but the polygon area algorithm shows that this will not affect the size of the area. Therefore, there is no need to make a detailed division when determining the two types of points.

[0082] When finding the area of ​​a triangle, the following formula is used:

[0083]

[0084] In the formula, (x0, y0), (x1, y1), (x2, y2) are the coordinates of the three vertices of the triangle respectively; and S3 is the directed area of ​​the triangle. The reason for using the directed area is that when determining the order of the vertices of the intersecting convex polygon, the directed area of ​​the triangle is used for direction judgment. If the three points of the triangle are arranged counterclockwise, the directed area is positive, otherwise it is negative.

[0085] It should be noted that, in the method of finding the first type of points, the "area of ​​the triangle" in the sum of the areas of the triangle formed by the point to be determined and all the sides of another polygon in sequence refers to the absolute value of the directed area of ​​the triangle, that is, the area without direction.

[0086] After finding all the vertices of the intersection convex polygon and determining the order of the vertices of the intersection convex polygon, the area of ​​the intersection convex polygon can be obtained by calculating the absolute value of the sum of the areas of triangles formed by any vertex of the intersection convex polygon and the remaining vertices in order. For example, the vertices of the intersection convex polygon are a, b, c, d, e and f in counterclockwise order, then the area of ​​the intersection convex polygon S6 = SΔabc + SΔacd + SΔade + SΔaef, wherein SΔabc is the absolute value of the directed area of ​​the triangle formed by the vertices a, b and c of the intersection convex polygon, SΔacd is the absolute value of the directed area of ​​the triangle formed by the vertices a, c and d of the intersection convex polygon, SΔade is the absolute value of the directed area of ​​the triangle formed by the vertices a, d and e of the intersection convex polygon, and SΔaef is the absolute value of the directed area of ​​the triangle formed by the vertices a, e and f of the intersection convex polygon.

[0087] Based on the above embodiment, optionally, the preset model is trained by the following method:

[0088] Based on the geometric parameters of each polygon initially input, the overlap area ratio between each two adjacent polygons is obtained; the overlap area ratio is the ratio of the overlap area of ​​two adjacent polygons to the area of ​​any one of the two adjacent polygons;

[0089] Specifically, firstly, multiple polygons are input as training samples. Based on the geometric parameters of each polygon initially input, the overlapping area and overlapping area ratio of two adjacent polygons can be calculated. The overlapping area ratio refers to the ratio of the overlapping area of ​​two adjacent polygons to the area of ​​any one of the polygons. For example, if the areas of two adjacent polygons are s1 and s2 respectively, and their overlapping area is s3, then their overlapping area ratio includes two values: s3 / s1 and s3 / s2.

[0090] If it is determined that the maximum value of each overlapping area ratio is greater than a preset threshold, the geometric parameters of each polygon are adjusted, and based on the adjusted geometric parameters of each polygon, each overlapping area ratio is re-obtained;

[0091] Specifically, if the maximum value of the overlap area ratio between each two adjacent polygons in each polygon initially input is calculated to be greater than the preset threshold value, the geometric parameters of each polygon can be adjusted, and based on the adjusted geometric parameters of each polygon, the overlap area ratio between each two adjacent polygons in each new polygon is calculated. The preset threshold value can be set according to actual needs or engineering design experience, and is not specifically limited. For example, the preset threshold value can be 30%.

[0092] The training is iterated continuously until the number of iterative training reaches the preset number, then the training stops and the preset model is obtained.

[0093] Specifically, the overlap area ratio between each two adjacent polygons in each adjusted polygon is continuously calculated by an iterative optimization method, so that the overlap area ratio between two adjacent polygons is less than a preset threshold value, and iterative training is continuously performed until the number of iterative training reaches a preset number, and then the training is stopped to finally obtain a preset model. The number of iterative training can be set according to actual needs, for example, it can be 100 times.

[0094] The method for adjusting base station engineering parameters provided in the embodiment of the present application continuously adjusts the overlapping area ratio between two adjacent polygons in each polygon through an iterative optimization method to make it less than a preset threshold, so that the training model finally obtained is used for base station site optimization, which can quickly give optimized site distribution suggestions, reduce labor costs, and perform large-scale site distribution optimization.

[0095] On the basis of the above embodiment, optionally, determining the polygon corresponding to each base station and used to characterize the coverage range of the base station signal based on the initial working parameter information includes:

[0096] Convert the longitude and latitude coordinates of each base station in the initial engineering parameter information into the corresponding longitude and latitude coordinates in the projection coordinate system;

[0097] Specifically, the longitude and latitude coordinates of the base station location in the initial engineering parameter information of the base station usually obtained are the longitude and latitude coordinates in the geographic coordinate system (for example, the World Geodetic System WGS84 coordinate system or the National Geodetic Coordinate System CGCS2000 coordinate system). Since the geographic coordinate system is a spherical coordinate system, in order to accurately calculate the polygon vertex coordinates corresponding to each base station for characterizing the base station signal coverage range, the longitude and latitude coordinates of the base station location can be first converted to a projection coordinate system such as the Mercator projection Mercator coordinate system. The projection coordinate system is a plane coordinate system, which can more accurately calculate the polygon vertex coordinates corresponding to each base station for characterizing the base station signal coverage range.

[0098] Taking the conversion from WGS84 coordinate system to Mercator coordinate system as an example, the conversion formula is as follows:

[0099] Longitude in Mercator coordinate system = lonLat.X*20037508.34 / 180;

[0100] Latitude in Mercator coordinate system = Math.Log(Math.Tan((90+lonLat.Y)*Math.PI / 360)) / (Math.PI / 180)*20037508.34 / 180;

[0101] In the formula, lonLat.X represents the longitude in the WGS84 coordinate system, lonLat.Y represents the latitude in the WGS84 coordinate system, Math.Log represents the logarithm of the natural number base of the return parameter, Math.Tan represents the tangent value of the return parameter, and Math.PI represents the value of pi π.

[0102] Based on the corresponding longitude and latitude coordinates in the projected coordinate system and the initial engineering parameter information, the longitude and latitude coordinates of the polygon vertices corresponding to each base station in the projected coordinate system for representing the coverage range of the base station signal are obtained;

[0103] Specifically, after the longitude and latitude coordinates of the base station location are transferred to the projection coordinate system, the longitude and latitude coordinates of the polygon vertices corresponding to each base station for representing the base station signal coverage range can be obtained in the projection coordinate system based on the longitude and latitude coordinates of the base station location and the initial engineering parameter information.

[0104] The longitude and latitude coordinates of the polygon vertices are converted into a geographic coordinate system to generate polygons corresponding to each base station in the geographic coordinate system for representing the coverage range of the base station.

[0105] Specifically, after calculating the longitude and latitude coordinates of the polygon vertices corresponding to each base station for representing the base station signal coverage range in the projection coordinate system, the longitude and latitude coordinates of the polygon vertices corresponding to each base station for representing the base station signal coverage range in the projection coordinate system can be converted to a geographic coordinate system such as the WGS84 coordinate system, and the vertices are converted into polygons and input into the preset model for subsequent optimization processing.

[0106] The method for adjusting the base station engineering parameters provided in the embodiment of the present application calculates the longitude and latitude coordinates of the polygon vertices corresponding to each base station for characterizing the base station signal coverage range by converting the longitude and latitude coordinates of the base station location in the initial engineering parameter information of the base station into a projection coordinate system, thereby improving the accuracy of the polygon vertex coordinate calculation.

[0107] Figure 3 A flow chart of a method for adjusting base station working parameters provided in an embodiment of the present application is shown as follows: Figure 3 As shown, based on the above embodiment, optionally, before determining the polygon corresponding to each base station and used to characterize the base station signal coverage range based on the initial working parameter information, the method further includes:

[0108] If it is determined that the downtilt angle in the initial working parameter information is reasonable, a polygon corresponding to each base station and used to characterize the coverage range of the base station signal is determined based on the initial working parameter information.

[0109] Specifically, after obtaining the initial working parameter information corresponding to each base station, it is possible to first determine whether the downtilt angle in the initial working parameter information is reasonable based on empirical data, for example, whether there is a downtilt angle that is significantly larger than the empirical data. If the downtilt angle in the initial working parameter information is reasonable, then the polygon corresponding to each base station for characterizing the base station signal coverage range is determined based on the initial working parameter information. Otherwise, it is determined that the corresponding base station working parameter is abnormal and the base station setting is unreasonable.

[0110] The method for adjusting the base station working parameters provided in the embodiment of the present application improves the optimization efficiency of the base station site by first judging whether the downtilt angle in the working parameter information is reasonable after importing the base station working parameters, and promptly identifying the base stations with abnormal working parameters.

[0111] The methods and devices provided in the various embodiments of the present application are based on the same application concept. Since the methods and devices solve problems based on similar principles, the implementation of the devices and methods can refer to each other, and the repeated parts will not be repeated.

[0112] Figure 4 A schematic diagram of the structure of an electronic device provided in an embodiment of the present application, such as Figure 4 As shown, the electronic device includes a memory 420, a transceiver 410 and a processor 400; wherein the processor 400 and the memory 420 may also be arranged physically separately.

[0113] The memory 420 is used to store computer programs; the transceiver 410 is used to send and receive data under the control of the processor 400.

[0114] Specifically, the transceiver 410 is used to receive and send data under the control of the processor 400 .

[0115] Among them, Figure 4 In the embodiment, the bus architecture may include any number of interconnected buses and bridges, specifically one or more processors represented by processor 400 and various circuits of memory represented by memory 420 are linked together. The bus architecture may also link together various other circuits such as peripherals, voltage regulators, and power management circuits, which are well known in the art and are therefore not further described in this application. The bus interface provides an interface. The transceiver 410 may be a plurality of components, namely, a transmitter and a receiver, providing a unit for communicating with various other devices on a transmission medium, which transmission medium includes a wireless channel, a wired channel, an optical cable, and other transmission media. The processor 400 is responsible for managing the bus architecture and general processing, and the memory 420 may store data used by the processor 400 when performing operations.
