Detailed Description
The embodiment of the invention provides a positioning method, a positioning device and positioning equipment.
In order to make the technical solution of the present invention better understood by those skilled in the art, the technical solution of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention, and it is apparent that the described embodiments are only some embodiments of the present invention, not all embodiments. All other embodiments, which can be made by those skilled in the art based on the embodiments of the invention without making any inventive effort, shall fall within the scope of the invention.
Example 1
As shown in fig. 1, an embodiment of the present invention provides a positioning method, where an execution body of the method may be a server, and the server may be an independent server or a server cluster formed by a plurality of servers. The method specifically comprises the following steps:
in S102, an initial position 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, a neighbor cell identifier, a user-to-serving cell time advance, a user-to-serving cell antenna arrival angle, serving cell and neighbor cell measurement levels, a measurement adoption period reporting timestamp, 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, application scenarios based on positioning technology are increasing, and how to prepare and acquire location information of a user becomes a focus of attention of operators. Currently, the location of a user can be determined by the location of the base station to which the user's device signal is attached. For example, the location information of the user with the device signal attached to the base station can be determined according to the longitude and latitude coordinates of the base station and in combination with the preset signal coverage area of the base station, that is, the location of the user with the device signal attached to the base station is realized.
However, since the coverage area of the preset signal of the base station is large and varies from hundreds of meters to hundreds of kilometers, the positioning accuracy is poor when the user is positioned through the coverage area of the preset signal of the base station. For this purpose, another implementation scheme is provided in the embodiment of the present invention, which specifically may include the following:
as shown in fig. 2, the target user may be located at the crossing position of the signal coverage areas of the plurality of base stations, and the device of the target user may receive signals from the plurality of base stations, so that information, such as signal strength, signal frequency, and the like, of signals received by the target user from the plurality of base stations may be obtained according to the device signal measurement report (such as MR) of the target user, and by using these information, the relative position between the target user and each of the plurality of base stations may be determined, and then the initial position of the target user may be determined according to the relative position between the target user and each of the base stations.
The above method for determining the initial position of the target user is an optional and implementable method, and besides the above method, there may be a plurality of different determining methods in different practical application scenarios, which is not limited in particular by the embodiment of the present invention.
In S104, based on the target parameters of the target base station, determining a signal coverage area of the target base station, and performing rasterization processing on the signal coverage area by a preset scale.
The target parameters may include an antenna height, an antenna downtilt angle, and a power angle of the target base station, where the target base station may be a base station to which a device signal of the target user is attached, for example, as shown in fig. 2, the device of the target user may receive signals of the base station 1, the base station 2, and the base station 3, but the device signal of the target user is finally attached to the base station 1, where the base station 1 may be a target base station, and the preset scale may be any scale, for example, the preset scale may be 10 m×10 m.
In implementation, for example, a signal of a target base station may cover multiple cells at the same time, and signal coverage areas of the target base station for different cells may be determined according to target parameters of the target base station for different cells. After determining the signal coverage area of the target base station, the target signal coverage area may be rasterized based on a preset scale. For example, according to target parameters of the target base station for different cells, determining signal coverage areas of the target base station for different cells, and then rasterizing the signal coverage areas of the target base station based on a preset scale to obtain a rasterized signal coverage area 1, a rasterized signal coverage area 2 and a rasterized signal coverage area 3, which are used as the rasterized signal coverage areas of the target base station.
In an actual application scenario, methods for determining a signal coverage area of a target base station based on a target parameter are various, and may be different according to different actual application scenarios, which is not particularly 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 signal coverage area after rasterization processing may be corrected according to the initial position of the target user, and then the target user may be positioned according to the signal coverage area of the corrected target base station. For example, the signal coverage areas of the target base stations after the rasterization processing 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 the point a and the point a is outside the signal coverage area 1, the signal coverage area 1 may be enlarged to a signal coverage area 1' including the point a, that is, the signal coverage area 1' is used as the signal coverage area of the target base station after the rasterization processing 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 based on a device signal measurement report of the target user, determining a signal coverage area of the target base station based on target parameters of the target base station, rasterizing the signal coverage area by a preset scale, wherein the target parameters comprise antenna height, antenna downward inclination angle and power angle of the target base station, and positioning the target user based on the initial position and the rasterized signal coverage area. In this way, 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 accuracy of positioning the target user can be improved through positioning the target user through the initial position of the target user and the signal coverage area obtained after the rasterization processing.
Example two
As shown in fig. 3, an embodiment of the present invention provides a positioning method, where an execution body of the method may be a server, and the server may be an independent server or a server cluster formed by a plurality of servers. The method specifically comprises the following steps:
in S302, an initial position of the target user is determined based on the device signal measurement report of the target user.
In practice, the above-mentioned processing manner of S302 may be varied, and the following provides an alternative implementation manner, which can be seen from the following steps one to three:
step one, based on the device signal measurement report of the target user, acquiring signal transmitting power and cell signal reference power of each base station from a plurality of base stations including the target base station received by the device of the target user at a preset time point.
And step two, determining the distance between the target user and each base station based on the signal transmitting power of each base station and the cell signal reference power.
In practice, 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 transmitting power of each base station, RSRP is the cell signal reference power of each base station, K 1 、K 2 、K 3 、K 4 Heff and Clutter_offset are preset parameters.
The preset parameters may be obtained through historical data training or manually preset according to experience, and the method for determining the preset parameters in the embodiment of the invention is not particularly limited.
And thirdly, determining the initial position of the target user based on the distance between the target user and each base station and the position coordinate of each base station.
In implementation, the position coordinates corresponding to each base station may be obtained according to the position coordinates of each base station and the distance between the target user and each base station, that is, assuming that n base stations (including the target base station) are included, the position coordinates of 3 target users may be obtained correspondingly, and then the distance between each position coordinate and 3 base stations may be calculated according to the 3 position coordinates, and the position corresponding to the position coordinate with the smallest sum of the distances may be used as the initial position of the target user.
For example, assuming that the master cell and neighbor cells have n base stations in total, one can follow the formula
......
Obtain the position coordinates (x) 1 ，y 1 )，(x 2 ，y 2 )，...，(x n ，y n ) The numerical value of the position coordinates of the target user is such that, for a circle formula with center coordinates
Minimum, therefore solving the above equation, x can be obtained mr And y mr I.e. the location 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 practice, in the GSM system, the directional stations are generally divided into three cells, namely: a cell: the direction angle is 0 degrees, and the antenna points to the north; b cell: the direction angle is 120 degrees, and the antenna points to southeast; c cell: the direction angle is 240 degrees and the antenna is pointed southwest.
As shown in fig. 4, considering the factor of the antenna vertical half power angle, the signal coverage radius of the target base station may be calculated based on the half power angle (i.e., 1/2 power angle) of the target base station, 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 the formula arctan (H/D) +β/2, and the downtilt angle α of the antenna may be obtained. If the factor of the vertical half power included angle of the antenna is considered, the actual coverage distance should be a range from the "maximum coverage distance" to the "minimum coverage distance", and the obtained height, downtilt angle, half power angle, etc. of the antenna in the target parameters of the target base station may be used to calculate the actual coverage area of the antenna, that is, the base station coverage distance=station height/tan (downtilt angle pi/180), so as to calculate the signal coverage radius of the target base station.
In S306, the signal coverage area of the target base station is determined based on the longitude information, latitude information and signal coverage radius of the target base station, and the signal coverage area is rasterized by a preset scale.
In the implementation, the signal coverage area of the target base station may be calculated by a geodetic coordinate calculation formula based on the longitude information and latitude information of the target base station and the signal coverage radius of the target base station, and the actual coverage area latitude Φ2=asin (sin Φ1·cos δ+cos Φ1·sin δ·cos θ) may be obtained, and the actual coverage area longitude λ2=λ1+atan2 (sin θ·sin δ·cos Φ1, cos δ -sin Φ1·sin Φ2), where λ2 is the resultant longitude, λ1 is the starting longitude, Φ2 is the resultant latitude, Φ1 is the resultant latitude, θ is the angle, and δ represents the angular distance from north clockwise, that is, d/R, d is the distance, and R is the earth radius.
In S308, when 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 the preset time point is checked, to obtain the checked initial position of the target user.
In an implementation, if the collation process is a smoothing filter suppression noise collation 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 acquired. And based on the first position, the second position and the initial position of the target user, performing correction processing on the initial position of the target user at a preset time point.
For example, the intermediate values of the first position, the second position, and the initial position of the target user may be used as the initial position of the target user after the calibration at the preset time point. For example, the first position has a position coordinate (Lon i-1 ，Lat i-1 ) The position coordinates of the second position are (Lon i+1 ，Lat i+1 ) The position coordinates of the initial position are (Lon i ，Lat i )
Based on the formula
Lon i ＝(Lon i-1 +Lon i +Lon i+1 )/3
Lat i ＝(Lat i-1 +Lat i +Lat i+1 )/3
The initial position of the target user after the calibration can be obtained.
Alternatively, if the collation process is a position interpolation collation process, the first position of the target user at a point in time before the target point in time and the second position of the target user at a point in time after the target point in time may be acquired. And based on the first position, the corresponding time point, the second position and the corresponding time point, performing correction processing on the initial position of the target user at the preset time point.
For example, the position coordinates of the first position are (X i-1 ，Y i-1 ) The position coordinates of the second position are (X i+1 ，Y i+1 ) The position coordinates of the initial position are (X i ，Y i ) Then
X i ＝X i-1 +(X i+1 -X i-1 )*(t i -t i-1 )/(t i+1 -t i-1 )
Y i ＝Y i-1 +(Y i+1 -Y i-1 )*(t i -t i-1 )/(t i+1 -t i-1 )。
In S310, the signal coverage area after the rasterization is collated based on the initial position of the collated target user, and the target user is positioned based on the signal coverage area after the rasterization after the collation.
The specific processing procedure of S310 may be referred to the content related to S106 in the first embodiment, and will not be described herein.
