[0026] Exemplary embodiments of the present invention will be described in more detail below with reference to the accompanying drawings. Although exemplary embodiments of the present invention are shown in the accompanying drawings, it should be understood that the present invention can be implemented in various forms and should not be limited by the embodiments set forth herein. Rather, these embodiments are provided to enable a more thorough understanding of the present invention and to fully convey the scope of the present invention to those skilled in the art.

[0027] Figure 1The schematic diagram of the process of optimizing the azimuth angle of the LTE base station provided by the embodiment of the present invention is shown. The method for optimizing the azimuth angle of the LTE base station is applied to the server side, such as Figure 1 As shown, the method for optimizing the azimuth angle of the LTE base station includes:

[0028] Step S11: extracting parameter information of the LTE base station in the area where the target LTE base station is located, including area, station type, timing advance, longitude and latitude, azimuth, and average TA distance.

[0029] In this embodiment of the present invention, if the target LTE base station is a newly built base station, parameter information of all other LTE base stations in the area where the target LTE base station is located is extracted. If the target LTE base station is not a newly built base station, parameter information of the target LTE base station and all other LTE base stations in the area where the target LTE base station is located is extracted.

[0030] Step S12: Calculate the new position coordinates of the LTE base station according to the timing advance, the azimuth, the average TA distance and the longitude and latitude.

[0031] In this embodiment of the present invention, the new position coordinates of the LTE base station are calculated according to the timing advance, the azimuth, the average TA distance, and the longitude and latitude using the following relationship:

[0032]

[0033]

[0034] Among them, lon(2): longitude of the new position, lat(2): latitude of the new position,

[0035] lon(1): extracted longitude, lat(1): extracted latitude,

[0036] TA: Timing advance data extracted from the LTE base station, 1TA = 78 meters,

[0037] θ: The new position offset angle calculated from the LTE base station azimuth angle,

[0038] 2πr: circumference of the Earth,

[0039] α: The weighted value of the horizontal and vertical offset positions. When ta>1, α=(ta-1) / ta.

[0040] In step S12, new location coordinates of all extracted LTE base stations are obtained.

[0041] Step S13: Calculate the first azimuth angles of the plurality of LTE base stations that meet the conditions according to the longitude and latitude, the average TA distance, and the new position coordinates.

[0042] In an embodiment of the present invention, a plurality of LTE base stations that meet the conditions are first obtained, wherein the conditions include the direction of the determined new azimuth angle and the distance between the new position coordinates and the target LTE base station being less than the maximum distance. The direction of the new azimuth angle is specifically determined based on the extracted azimuth angle of the target LTE base station. Among them, direction 1 is [300°, 360°) and [0°, 60°)), direction 2 is [60°, 180°) and direction 3 is [180°, 300°). For the maximum distance, preferably, when the target LTE base station is located in a city, the maximum distance is 500 meters, and when the target LTE base station is located in a rural area, the maximum distance is 3000 meters.

[0043] Then, the quadrant in which the new location coordinates are located is determined. Specifically, a rectangular coordinate system is formed based on the latitude and longitude of the target LTE base station; and the quadrant in which the new location coordinates are located is determined based on the position of the new location coordinates in the rectangular coordinate system. [0°, 90°) is the first quadrant, [90°, 180°) is the second quadrant, [180°, 270°) is the third quadrant, and [270°, 360°) is the fourth quadrant.

[0044] Then, the azimuth offsets of the plurality of LTE base stations are calculated based on the longitude and latitude, the average TA distance, and the new location coordinates. Specifically, the length of the opposite side and the length of the right angle side of the azimuth offset are calculated based on the longitude and latitude, the average TA distance, and the new location coordinates by applying the following second relationship; and the azimuth offset is calculated based on the length of the opposite side and the length of the right angle side by applying an inverse trigonometric function.

[0045] L1=r*ACOS(sin(lat(2))*sin(lat(2))+cos(lat(2))*cos(lat(2))*cos(lon(2)-lon(1))),

[0046] L2=r*ACOS(sin(lat(2))*sin(lat(1))+cos(lat(2))*cos(lat(1))*cos(lon(2)-lon(1))),

[0047] β=arctan(L1 / L2),

[0048] Wherein, L1 is the length of the opposite side of the azimuth offset; L2 is the length of the right-angle side of the azimuth offset; β is the azimuth offset, which is used in subsequent calculations to obtain the first azimuth.

[0049] Finally, the first azimuth is determined based on the azimuth offset and the quadrant in which the new position coordinates are located. Specifically, a rectangular coordinate system is formed based on the latitude and longitude of the target LTE base station; and the quadrant in which the new position coordinates are located is determined based on the position of the new position coordinates in the rectangular coordinate system. If the new position coordinates are in the first quadrant, the first azimuth is determined to be equal to the azimuth offset β; if the new position coordinates are in the second quadrant, the first azimuth is determined to be equal to 180-the azimuth offset β; if the new position coordinates are in the third quadrant, the first azimuth is determined to be equal to the azimuth offset β+180; if the new position coordinates are in the fourth quadrant, the first azimuth is determined to be equal to 360-the azimuth offset β.

[0050] Step S14: Determine a new azimuth angle of the target LTE base station according to the first azimuth angles of the plurality of LTE base stations.

[0051] In an embodiment of the present invention, the load conditions of the first azimuth angles are obtained based on the peak utilization information; the second azimuth angle with the highest load and the third azimuth angle with the second highest load are obtained based on the load conditions; and the new azimuth angle of the target LTE base station is determined based on the second azimuth angle and the third azimuth angle. For example, N first azimuth angles that meet the conditions are obtained and recorded, and the peak utilization information P extracted from the existing LTE base station is used to obtain the new azimuth angle of the target LTE base station. N Corresponding to the first azimuth angle, the load conditions of N first azimuth angles are obtained, and the load values of the N first azimuth angles are compared using the following third relationship to obtain the second azimuth angle A1 with the highest load and the third azimuth angle A2 with the second highest load.

[0052] A1=MAX(P1,P2,P3,…,A1,…,P N ),

[0053] A2=MAX(P1,P2,P3,…,A2,…,P N-1 ).

[0054] After obtaining the second azimuth angle A1 and the third azimuth angle A2, the new azimuth angle of the target LTE base station is determined according to the second azimuth angle A1 and the third azimuth angle A2. Specifically, the antenna beam angle configured for the target LTE base station is determined; if the difference between the second azimuth angle and the third azimuth angle is greater than the antenna beam angle, the new azimuth angle is determined to be equal to the second azimuth angle; if the difference between the second azimuth angle and the third azimuth angle is less than or equal to the antenna beam angle, the new azimuth angle is determined to be equal to the average value of the second azimuth angle and the third azimuth angle. For example, it is determined that the antenna beam angle configured for the target LTE base station is 60 degrees, and the new azimuth angle of the target LTE base station is determined according to the following fourth relationship,

[0055]

[0056] Step S15: Optimize the azimuth angle of the target LTE base station according to the new azimuth angle.

[0057] If the deviation between the new azimuth and the azimuth of the target LTE base station is greater than a threshold, the azimuth of the target LTE base station is adjusted and optimized. If the deviation between the calculated new azimuth and the azimuth of the target LTE base station is greater than a threshold, it means that the cell corresponding to the target LTE base station does not normally cover the residential area, and there is a deviation, which will affect the user's Internet access perception. In this embodiment of the present invention, the threshold can be set as needed. Preferably, the threshold is 30 degrees. When adjusting and optimizing the azimuth of the target LTE base station, it can be arbitrarily adjusted within the range of direction and distance that meet the new azimuth, in order to improve the peak utilization rate of the adjusted azimuth.

[0058] The method for optimizing the azimuth angle of an LTE base station obtained in an embodiment of the present invention can be used for calculations of up to 100,000 data points. The average TA information of the base station is weighted and applied to the calculation of the new longitude and latitude, thereby improving the accuracy of the example of reusing the base station TA information for calculation, with higher accuracy; the peak utilization information of the LTE base station is applied to the azimuth angle calculation, thereby alleviating the high load problem in current mobile communications, and having higher application value; the position information of the first and second highest loads on the sphere is calculated using a formula, and then the angle formula is used to calculate the azimuth angle that meets the restriction conditions. The idea is clear and novel, and the novelty is higher.

[0059] The following example illustrates the extracted parameter information of the target LTE base station, which includes region, station type, longitude, latitude, azimuth, average TA distance, and peak utilization. The optimized cell in Table 1 refers to the cell to be optimized corresponding to the target LTE base station.

[0060] Table 1 Parameter information of target LTE base station

[0061]

[0062] The parameter information of the LTE base station in the area where the target LTE base station is located is applied to the new position coordinates calculated by the first relationship, and the distance from the new position coordinates to the longitude and latitude of the target LTE base station is calculated. The azimuth angle of the target LTE base station is 260 degrees, which belongs to the third quadrant, and the following is obtained: Figure 2 The LTE base station shown meets the requirements of 500 meters from the cell in the city and the third quadrant, that is, the corresponding cell.

[0063] According to the calculated new position coordinates, the second relationship is applied to calculate the opposite side length L1 of the azimuth offset and the right angle side length L2 of the azimuth offset, and then the azimuth offset β is calculated, thereby obtaining the first azimuth A=β+180. The first azimuth data obtained is as follows: Figure 3 shown.

[0064] According to the third relationship, we can get the second azimuth angle A1=243 for the highest load and the third azimuth angle A2=203 for the second highest load, as shown in the following example: Figure 4 shown.

[0065] The LTE base station antenna beam angle is configured to 60 degrees. The new azimuth angle A is calculated using the fourth equation: (A1 + A2) / 2 = 223. Since the azimuth angle of the target LTE base station is 260, the deviation is 37, which is greater than the threshold of 30. This indicates that the azimuth angle of the existing network is not configured properly.

[0066] Through on-site inspection, it was found that the optimized cell did not properly cover the residential area, there was a deviation, which seriously affected the user's Internet experience. The azimuth angle of the problem cell was adjusted from 260° to 240°, such as Figure 5 As shown, the adjusted peak utilization increased from 12% to 41%, an increase of 29%.

[0067] The embodiment of the present invention extracts parameter information of LTE base stations in the area where the target LTE base station is located, including area, station type, time advance, longitude and latitude, azimuth and average TA distance; calculates the new position coordinates of the LTE base station according to the time advance, the azimuth, the average TA distance and the longitude and latitude; calculates the first azimuths of multiple LTE base stations that meet the conditions according to the longitude and latitude, the average TA distance and the new position coordinates; determines the new azimuth of the target LTE base station according to the first azimuths of the multiple LTE base stations; and optimizes the azimuth of the target LTE base station according to the new azimuth, thereby improving the accuracy of LTE base station azimuth optimization and alleviating the high load problem in current mobile communications.
