Figure 1 As shown, a base station position correction method is provided, comprising the following steps: step 110, step 120 and step 130. The steps of the method flow are only a possible implementation of the present invention.
[0024] Step 110: Obtaining Minimization of Drive Tests (MDT) data of a target area; The target area includes an urban area and / or a suburban area, and each cell of the target base station is in the urban area.
[0025] Among them, Minimization of Drive Tests (MDT) data is mobile network performance data collected by minimizing actual drive test activities and using a variety of technical means and optimization methods.
[0026] Among them, MDT data includes uplink and downlink rates, delay, packet loss rate, reference signal reception power, reference signal reception quality, user terminal location information and other data.
[0027] Optionally, the user terminal automatically reports network performance data, such as signal strength, signal quality, and latency, during normal communication. The base station measures and reports various parameters related to user terminal communication, such as received power and interference level. These data are integrated to obtain MDT data.
[0028] Step 120: Calculate multiple timing advance (TA) values for each cell of the target base station based on the MDT data, and select multiple target TA values from the multiple TA values, where the multiple target TA values include a first target TA value, and the first target TA value is greater than a preset value. The Timing Advance (TA) value refers to the amount of time a user terminal sends a signal in advance to compensate for the delay caused by signal propagation between the base station and the user terminal in a mobile communication system. The TA value is calculated based on the distance between the user terminal and the base station.
[0029] Optionally, the preset value is determined based on user input or empirical data.
[0030] For example, the multiple target TA values are 1 μs, 2 μs, 3 μs, 4 μs, 5 μs, 6 μs, etc., the preset value is 1 μs, and the first target TA value is 2 μs, 3 μs, 4 μs, 5 μs, 6 μs, etc.
[0031] Step 130: Determine the inner and outer diameters of the ring corresponding to the first target TA value, and determine the first optimal position of the center of the ring corresponding to the first target TA value with the goal of maximizing the probability that the ring corresponding to the first target TA value covers the first grid. The first optimal position is determined as the first predicted position of the target base station; the first grid is the cell grid corresponding to the first target TA value.
[0032] It should be noted that on the electronic map of the target area, each cell is divided into multiple grids. The cell grid corresponding to the first target TA value represents the position of the user terminal corresponding to the first target TA value. There are multiple cell grids corresponding to the first target TA value.
[0033] Optionally, there are multiple first target TA values and corresponding rings, and the first optimal position is determined to be the center of the multiple rings so that the sum of the coverage of the corresponding first grid by each ring is maximized.
[0034] In an embodiment of the present invention, minimized drive test (MDT) data of a target area is obtained; based on the MDT data, multiple timing advance (TA) values of each cell of a target base station are calculated, and the multiple TA values are screened to obtain a first target TA value that is greater than a preset value; the inner and outer diameters of a circular ring corresponding to the first target TA value are determined, and with the goal of maximizing the probability that the circular ring corresponding to the first target TA value covers a first grid, a first optimal position of the center of the circular ring corresponding to the first target TA value is determined, and the first optimal position is determined as the first predicted position of the target base station, thereby improving the efficiency and accuracy of base station position correction.
[0035] In some embodiments, the plurality of target TA values include a second target TA value, the second target TA value being equal to a preset value, and the method further includes: Determine the radius of the circle corresponding to the second target TA value, and determine the second optimal position of the center of the circle corresponding to the second target TA value with the goal of maximizing the probability that the circle corresponding to the second target TA value covers the second grid. Determine the second optimal position as the second predicted position of the target base station; the second grid is the cell grid corresponding to the second target TA value.
[0036] The cell grid corresponding to the second target TA value represents the location of the user terminal corresponding to the second target TA value.
[0037] Figure 2 Schematic diagram of the second predicted position of the target base station provided by the embodiment of the present invention. Figure 2As shown, the second target TA value is 1 μs, the sampling number of the second grid corresponding to the second target TA value is 63, and the second optimal position of the center of the circle corresponding to the second target TA value is the second predicted position of the target base station.

If so, the original position of the target base station is determined to be an abnormal position, and the original position of the target base station is updated to the target position.
[0039] Optionally, the original location of the target base station is obtained through a geographic information system, or the original location of the target base station is determined by obtaining a network planning document, or the original location of the target base station is determined by an on-site survey.
[0040] In some embodiments, screening out multiple target TA values from multiple TA values includes: Divide each cell into multiple grids and determine the number of grids corresponding to each TA value; It is determined whether the number of grids corresponding to each TA value is greater than a preset grid number threshold. If so, each TA value is determined as a target TA value.
[0041] Optionally, a preset grid quantity threshold, such as 10, is determined based on user input or empirical data.
[0042] Optionally, the number of grid sampling points corresponding to each TA value is determined according to the MDT data, and when the number of grid sampling points corresponding to each TA value is greater than a preset sampling point number threshold, each TA value is determined to be a target TA value.
[0043] It can be understood that by screening multiple TA values, multiple target TA values with higher accuracy can be obtained.

[0045] Optionally, pre-processing such as data cleaning, data conversion, and interpolation is performed on the MDT data.
[0046] Optionally, a plurality of first signal propagation delays from the plurality of user terminals to the target base station is estimated using an existing signal propagation model, where the model takes into account various factors in the signal propagation process, such as distance, obstacle attenuation, etc.
[0047] Optionally, the accuracy of the calculated TA value is verified by actual network performance indicators.
[0048] In some embodiments, after obtaining the MDT data of the target area, the method further includes: Calculate multiple TA values of the target cell based on the MDT data; Divide the target cell into multiple target grids; Determine multiple TA distances and multiple target grids corresponding to multiple TA values of the target cell; Determine the locations of multiple target grids; With the position of each target grid as the center of the circle and the TA distance corresponding to each target grid as the radius, determine the circle corresponding to each target grid; The location of the base station of the target cell is determined based on the circle corresponding to each target grid.
[0049] Among them, the target cell is in the suburbs, and the distribution of multiple TA values of the target cell is relatively discrete.
