Detailed Description
The embodiment of the invention provides a positioning method, a positioning device and positioning equipment.
In order to make those skilled in the art better understand the technical solution of the present invention, the technical solution in the embodiment of the present invention will be clearly and completely described below with reference to the drawings in the embodiment of the present invention, and it is obvious that the described embodiment is only a part of the embodiment of the present invention, and not all embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
Example one
As shown in fig. 1, an execution subject of the method may be a server, and the server may be an independent server or a server cluster composed of a plurality of servers. The method may specifically comprise the steps of:
in S102, an initial location of the target user is determined based on the device signal measurement report of the target user.
The device signal measurement report may include a serving cell identifier, an adjacent cell identifier, a time advance from the user to the serving cell, an antenna arrival angle from the user to the serving cell, measurement levels of the serving cell and the adjacent cell, a periodic reporting timestamp for measurement, and the like, where the target user is any user using mobile communication. In practical applications, the device signal Measurement Report may be MR (Measurement Report) or the like.
In implementation, with the continuous development of computer technology, the number of application scenarios based on positioning technology is increasing, and how to prepare to acquire the location information of the user becomes a focus of attention of operators. Currently, the location of the user can be determined by the location of the base station to which the device signal of the user is attached. For example, the location information of the user whose device signal is attached to the base station may be determined according to the longitude and latitude coordinates of the base station and in combination with the preset signal coverage of the base station, that is, the location of the user whose device signal is attached to the base station is implemented.
However, the preset signal coverage of the base station is large, and ranges from hundreds of meters to hundreds of kilometers, so that the user is positioned through the preset signal coverage of the base station, and the positioning accuracy is poor. Therefore, another implementation scheme is provided in the embodiments of the present invention, which may specifically include the following:
as shown in fig. 2, the target user may be located at an intersection of signal coverage areas of a plurality of base stations, and the device of the target user may receive signals from the plurality of base stations, so that information of the signals received by the target user from the plurality of base stations, such as signal strength, signal frequency, and the like, may be obtained according to a device signal measurement report (such as MR) of the target user, and from the information, a relative position between the target user and each base station of the plurality of base stations may be determined, and then an initial position of the target user may be determined according to the relative position between the target user and each base station.
The method for determining the initial position of the target user is an optional and realizable determination method, and besides the determination method, in different practical application scenarios, there may be a plurality of different determination methods, which is not specifically limited in the embodiment of the present invention.
In S104, a signal coverage area of the target base station is determined based on the target parameter of the target base station, and the signal coverage area is rasterized by a preset scale.
For example, as shown in fig. 2, the device of the target user may receive signals of base stations 1, 2, and 3, but the device signal of the target user is finally attached to base station 1, and then base station 1 may be the target base station, and the preset scale may be any scale, for example, the preset scale may be 10 meters by 10 meters.
In implementation, for example, the signal of the target base station may cover multiple cells simultaneously, and the signal coverage area of the target base station for different cells may be determined according to the target parameters of the target base station for different cells, respectively. After the signal coverage area of the target base station is determined, rasterization processing may be performed on the target signal coverage area based on a preset scale. For example, according to target parameters of the target base station for different cells, signal coverage areas of the target base station for the different cells are determined, and then the signal coverage areas of the target base station are rasterized based on a preset scale, so that a rasterized signal coverage area 1, a rasterized signal coverage area 2, and a rasterized signal coverage area 3 are obtained and serve as the rasterized signal coverage areas of the target base station.
In an actual application scenario, there are various methods for determining a signal coverage area of a target base station based on a target parameter, which may be different according to different actual application scenarios, and this is not specifically limited in the embodiment of the present invention.
In S106, the target user is located based on the initial position and the signal coverage area after the rasterization processing.
In implementation, the coverage area of the signal after the rasterization process may be corrected according to the initial position of the target user, and then the target user may be located according to the corrected coverage area of the signal of the target base station. For example, the signal coverage area of the target base station after the rasterization process may include a signal coverage area 1 for a cell 1, a signal coverage area 2 for a cell 2, and a signal coverage area 3 for a cell 3. If the initial position of the target user is located at point a and point a is outside the signal coverage area 1, the signal coverage area 1 may be expanded to a signal coverage area 1 ' including point a, that is, the signal coverage area 1 ' is used as a signal coverage area of the target base station after the rasterization process for the cell 1, and at the next time point, the target user is located through the signal coverage area 1 ', the signal coverage area 2 and the signal coverage area 3, and the position, the action track, and the like of the target user are determined.
The embodiment of the invention provides a positioning method, which comprises the steps of determining an initial position of a target user through an equipment signal measurement report based on the target user, determining a signal coverage area of a target base station based on target parameters of the target base station, rasterizing the signal coverage area through a preset scale, wherein the target parameters comprise the antenna height, the antenna downtilt and the power angle of the target base station, and positioning the target user based on the initial position and the rasterized signal coverage area. Therefore, the actual signal coverage area of the target base station can be accurately determined through the target parameters of the target base station, so that the target user is positioned through the initial position of the target user and the signal coverage area obtained after rasterization, and the accuracy of positioning the target user can be improved.
Example two
As shown in fig. 3, an execution subject of the method may be a server, and the server may be an independent server or a server cluster composed of a plurality of servers. The method may specifically comprise the steps of:
in S302, an initial location of the target user is determined based on the device signal measurement report of the target user.
In practice, the processing manner of S302 may be varied in practical applications, and an alternative implementation manner is provided below, which may specifically refer to the following steps one to three:
step one, acquiring a signal transmission power and a cell signal reference power of each base station in a plurality of base stations including a target base station, which are received by equipment of a target user at a preset time point based on an equipment signal measurement report of the target user.
And step two, determining the distance between the target user and each base station based on the signal transmission power of each base station and the cell signal reference power.
In implementation, the signal transmission power of each base station and the cell signal reference power can be substituted into the formula
Obtaining the distance between the target user and each base station, wherein d is the distance between the target user and each base station, BSPWR is the signal transmission power of each base station, RSRP is the cell signal reference power of each base station, K1、K2、K3、K4Heff and Cluter _ offset are preset parameters.
The preset parameters may be obtained through historical data training or may be preset manually according to experience, and the method for determining the preset parameters in the embodiment of the present invention is not particularly limited.
And step three, determining the initial position of the target user based on the distance between the target user and each base station and the position coordinates of each base station.
In implementation, the position coordinate corresponding to each base station may be obtained according to the position coordinate of each base station and the distance between the target user and each base station, that is, assuming that there are n base stations (including the target base station), the position coordinates of 3 target users may be correspondingly obtained, and then the distance between each position coordinate and 3 base stations may be calculated according to the 3 position coordinates, respectively, and the position corresponding to the position coordinate with the minimum sum of the distances is taken as the initial position of the target user.
For example, assuming that there are n base stations in total in the master cell and the neighbor cells, the formula can be based on
......
Obtaining the position coordinates (x) of each base station1，y1)，(x2，y2)，...，(xn，yn) A circular formula with a center coordinate, the value of the location coordinate of the target user would be
Minimum, so solving the above equation, x can be obtainedmrAnd ymrI.e. the position coordinates of the target user.
In S304, a signal coverage radius of the target base station is determined based on the target parameter of the target base station.
In implementation, in the GSM system, the directional station is generally divided into three cells, namely: and A, cell: the direction angle is 0 degree, and the antenna points to the north; and B, cell: the direction angle is 120 degrees, and the antenna points to the south east; c, cell: the direction angle is 240 degrees, and the antenna points to the southwest.
As shown in fig. 4, considering the antenna vertical half power angle, the signal coverage radius of the target base station may be calculated based on the half power angle of the target base station (i.e., power angle of 1/2), i.e., the signal coverage radius of the target base station is between the minimum coverage radius and the maximum coverage radius.
The antenna height H, the antenna downtilt angle D and the power angle β/2 of the target base station may be substituted into a formula arctan (H/D) + β/2 to obtain the downtilt angle α of the antenna. If the factors of the vertical half-power angle of the antenna are considered, the actual coverage distance should be a range from the "maximum coverage distance" to the "minimum coverage distance", and the actual coverage range of the antenna, that is, the base station coverage distance is equal to station height/tan (downward inclination angle × pi/180), may be calculated by using the height of the antenna, the downward inclination angle of the antenna, the half-power angle, and the like in the acquired target parameters of the target base station, so as to calculate the signal coverage radius of the target base station.
In S306, a signal coverage area of the target base station is determined based on the longitude information, the latitude information, and the signal coverage radius of the target base station, and the signal coverage area is rasterized by a preset scale.
In an embodiment, the signal coverage area of the target base station may be calculated by a geodetic coordinate calculation formula based on the coordinates of the target base station, the longitude information and the latitude information of the target base station, and the signal coverage radius of the target base station, so that an actual coverage area latitude Φ 2(sin Φ 1 · cos δ + cos Φ 1 · sin δ · cos θ), and an actual coverage area longitude λ 2(sin θ · sin δ · cos Φ 1, cos δ — sin Φ 1 · sin Φ 2) may be obtained, where λ 2 is the result longitude, λ 1 is the start longitude, Φ 2 is the result latitude, Φ 1 is the result latitude, θ is the angle, δ is the angular distance, that is, d/R, d is the distance, and R is the earth radius.
In S308, in a case that the initial position of the target user is not within the signal coverage area of the target base station, the initial position of the target user at a preset time point is corrected, so as to obtain the corrected initial position of the target user.
In implementation, if the correction process is a smoothing filter suppression noise correction process, a first position of the target user at a time point before the target time point and a second position of the target user at a time point after the target time point may be obtained. And performing correction processing on the initial position of the target user at the preset time point based on the first position, the second position and the initial position of the target user.
For example, the intermediate value of the first position, the second position and the initial position of the target user may be used as the initial position of the corrected target user at the preset time point. For example, the position coordinate of the first position is (Lon)i-1，Lati-1) The position coordinate of the second position is (Lon)i+1，Lati+1) The position coordinate of the initial position is (Lon)i，Lati)
Based on the formula
Loni＝(Loni-1+Loni+Loni+1)/3
Lati＝(Lati-1+Lati+Lati+1)/3
The corrected initial position of the target user can be obtained.
Alternatively, if the correction processing is the position interpolation correction processing, the first position of the target user at a time point before the target time point and the second position of the target user at a time point after the target time point may be acquired. And performing correction processing on the initial position of the target user at the preset time point based on the first position and the corresponding time point, the second position and the corresponding time point.
For example, the position coordinate of the first position is (X)i-1，Yi-1) The position coordinate of the second position is (X)i+1，Yi+1) The position coordinate of the initial position is (X)i，Yi) Then, then
Xi＝Xi-1+(Xi+1-Xi-1)*(ti-ti-1)/(ti+1-ti-1)
Yi＝Yi-1+(Yi+1-Yi-1)*(ti-ti-1)/(ti+1-ti-1)。
In S310, the coverage area of the rasterized signal is corrected based on the corrected initial position of the target user, and the target user is located based on the corrected coverage area of the rasterized signal.
For the specific processing procedure of S310, reference may be made to the relevant content of S106 in the first embodiment, which is not described herein again.

Therefore, the actual signal coverage area of the target base station can be accurately determined through the target parameters of the target base station, so that the target user is positioned through the initial position of the target user and the signal coverage area obtained after rasterization, and the accuracy of positioning the target user can be improved.
