As shown in fig. 1, an embodiment of the present invention provides a positioning method, which specifically includes the following steps:
The M base stations are all base stations participating in positioning, and the target measurement quantity may be one of multiple measurement quantities such as TOA, TDOA, AOA, and the like. The target measurement quantity can be used for representing the distance between a base station and the terminal to be positioned. And calculating the target measurement quantity between the terminal to be positioned and the M base stations participating in positioning, estimating the position according to the measurement quantity, and determining the target base station closest to the terminal to be positioned.
And step 102, under the condition that the target measurement quantity between the target base station and the terminal to be positioned meets a first condition, positioning the terminal to be positioned by using base stations except the target base station in the M base stations.
Determining the distance between the target base station and the terminal to be positioned according to the target measurement quantity between the target base station and the terminal to be positioned, wherein under the condition that the target measurement quantity meets a first condition, the distance between the target base station and the terminal to be positioned can be indicated to be short, in order to avoid positioning errors of the terminal to be positioned caused by the short distance, when the terminal to be positioned is positioned, the target base station is removed, namely the information of the target base station is not used, and other base stations except the target base station in M base stations participating in positioning are used for positioning the terminal to be positioned.
According to the embodiment of the application, the distance between the terminal to be positioned and each base station participating in positioning can be determined according to the target measurement quantity, and the distance between the terminal to be positioned and the target base station closest to the terminal to be positioned can be determined, so that the base station which can be used for positioning is selected from the base stations participating in positioning, and the terminal to be positioned is positioned. According to the embodiment, the effective positioning base station is selected according to the condition that the distance between the terminal to be positioned and the base station is short, so that the positioning error caused by the fact that the distance between the base station and the terminal is short is avoided, the positioning precision near the position of the base station can be improved, and the accuracy of positioning the terminal is improved.
Specifically, the first condition may include: the target measurement quantity between the target base station and the terminal to be positioned is less than or equal to a target threshold value; the target measurement quantity is used for indicating the distance between the target base station and the terminal to be positioned.
The target threshold is a threshold related to the target measurement amount, and may be set according to conditions such as an algorithm of the target measurement amount, an application scenario, and the like. In this embodiment, when the target measurement amount between the target base station and the terminal to be positioned is less than or equal to the target threshold, the base stations other than the target base station are used to position the terminal to be positioned.
Taking the target measurement amount as TOA as an example, the total number of base stations participating in positioning calculation is M, namely BS i (i ═ 1,2, …, M), performing position estimation according to the target measurement TOA (or TDOA), and selecting the target base station BS closest to the position of the terminal to be positioned i,Min Determining the distance between the terminal to be positioned and the target base station BS according to the target measurement TOA i,Min If the target base station BS i,Min The target measurement TOA between the terminal to be positioned and the terminal is less than or equal to a target threshold value, namely
Wherein the content of the first and second substances,
for the terminal to be positioned and the target base station BS i,Min The TOA measurement value of (a), TH, is a target threshold value related to the target measurement TOA, and may be determined according to a specific algorithm and a specific usage scenario. At this time, the distance between the terminal to be positioned and the target base station is close, and if the first condition is met, the target base station BS closest to the terminal to be positioned is excluded from the M base stations i,Min And positioning and calculating the terminal to be positioned by using the information of the rest M-1 base stations.
Optionally, when the target measurement quantity between the target base station and the terminal to be positioned does not satisfy the first condition, the terminal to be positioned is positioned by using the M base stations. And when the target measurement quantity between the target base station and the terminal to be positioned is larger than a target threshold value, the M base stations are utilized to perform positioning calculation on the terminal to be positioned.
It should be noted that, in the following description,the target measurement quantity may be selected as desired. As an optional embodiment, the target measurement quantity may also be TDOA, and it is assumed that there are M base stations in the positioning system to locate the terminal to be located, the position coordinate of the terminal to be located is (X, y), and the position coordinate of the base station is (X, y) i ,Y i ) I is more than or equal to 1 and less than or equal to M, wherein, the signals of the M-1 base stations reaching the terminal to be positioned and the serving base station BS 1 The time difference of incoming waves between signals (namely the target base station) reaching the terminal to be positioned is t i I — 1,2,3, …, M, which can be calculated by the TDOA principle:
let r be i -r 1 ＝r i1 ，k i ＝X i 2 +Y i 2 By linearizing the equation, one can obtain:
r i1 2 +2·r i1 r 1 ＝-2·(Y i -Y 1 )·y+k i -k 1 ，i＝2,3,…,M； (1)
wherein r is i Is a base station (X) i ,Y i ) Distance from terminal (x, y) to be positioned, r 1 For serving base station BS 1 And c is the speed of light.
For the solution of the above equation, an LS algorithm, a Chan algorithm or a Taylor series expansion algorithm can be adopted, wherein the LS algorithm is to eliminate r from M-1 formulas in the above formula (1) 1 Term, establish h ═ Z · V T ·(V·V T ) -1 Is solved, h ═ x, y]. The Taylor series expansion algorithm is based on an initial position (X) 0 ,Y 0 ) Calculating r i And then calculate h t And G t And calculating by combining the covariance matrix Q
According to (X) 0 +Δx,Y 0 + Δ y) continues the calculation. ChThe an algorithm assumes that P ═ X, Y, r] T ，h c ＝G c P+ε c Wherein, in the step (A),
P＝(G c T Q -1 G c ) -1 G c T Q -1 h c
wherein Q is a covariance matrix of TDOA measurement error, and is a substitution error epsilon c The covariance matrix of (c).

So as to determine the target base station closest to the terminal to be positioned according to the target measurement quantity. And under the condition that the target measurement quantity between the target base station and the terminal to be positioned meets the first condition, excluding the target base station with the shortest distance so as to determine M-1 base stations participating in positioning, and performing positioning calculation on the terminal to be positioned according to the information of the M-1 base stations and a predetermined positioning algorithm.

Taking the different values of M of multiple positioning calculations as an example, positioning the terminal to be positioned for N times to obtain N positioning results; wherein, M values of each positioning in N times of positioning are different; processing the N positioning results to obtain a target positioning result; n is greater than or equal to 2.
Specifically, the processing the N positioning results to obtain the target positioning result may include: and averaging or filtering the N positioning results to obtain the target positioning result.

It should be noted that if the values of M calculated by multiple positioning calculations are the same, multiple measurements (e.g., N times) may be performed on each value of M, and an average value or a filtered value of the multiple measurements is used as a final positioning result.
As an alternative embodiment, as shown in fig. 2, the implementation process of the positioning method is described below by a specific embodiment.

step 2: selecting the base station BS nearest to the position of the terminal to be positioned according to the measurement quantity i,Min I.e. the target base station;
and step 3: calculating a terminal to be positioned and a base station BS i,Min If said distance satisfies a predetermined first condition (if a TOA measurement is used, it is necessary to determine whether or not the condition is satisfied
If yes, the terminal to be positioned and the base station BS are considered i,Min The distance is short), the next selection of the base station is carried out, and then the position of the terminal to be positioned is calculated;
and 4, step 4: excluding the nearest base station BS i,Min Then M-1 base stations which are closer to the position of the terminal to be positioned are determined;
and 5: and performing positioning calculation on the position of the terminal to be positioned according to the selected information of the M-1 base stations and a predetermined positioning algorithm.

And determining the base station closest to the terminal to be positioned as the target base station according to the measurement result of the measurement quantity. According to the measurement result of the measurement quantity, the distance between the terminal to be positioned and the target base station can be judged, and if the terminal to be positioned is judged to be very close to the target base station (meeting a first condition), a base station which can be used for positioning needs to be selected from all base stations participating in positioning (the target base station is excluded) for positioning. Otherwise, directly performing positioning calculation according to all base stations participating in positioning.
The number of base stations used for positioning may be one value or a plurality of different values. The calculation times of the positioning can be one time or multiple times; when a plurality of positioning results are obtained through multiple calculations, the final positioning result can be obtained through processing by a filtering or averaging method.
