As shown in FIG. 1 , an execution body of the method in this embodiment may be a mobile terminal, where the mobile terminal has a function of acquiring a positioning signal indicated by positioning signal configuration information. The method comprises the following steps:

Step 101: The mobile terminal acquires positioning signal information.

The positioning signal information in this embodiment includes a time parameter type for measuring the positioning signal and/or a time parameter corresponding to the time parameter type. The time parameter corresponding to the time parameter type includes a measurement result obtained by the mobile terminal according to the time parameter type, that is, a time parameter.

During the propagation of radio waves, due to the blocking, reflection and penetration of obstacles such as buildings, trees, hillsides, etc., a plurality of different paths are formed by the base station to the mobile station or by the mobile station to the base station. In the process of receiving the wireless signal of the base station by the mobile station, a corresponding plurality of identical content signals are received, and each signal corresponds to one propagation path. These signals will arrive at the mobile station one after the other, and the corresponding mobile station will receive these signals in succession. Signals of different paths have different propagation delays, and the power received by the mobile station is also different. The mobile station confirms the signals of different paths under different delays by measuring the received signals, wherein the path signal with the smallest delay is the first path signal; in the confirmed multipath signal, the power is the largest The signal is the strongest power signal; wherein the path signal with the largest delay is the Nth path signal, and it is assumed that N path signals are confirmed. The first arrival time of the signal refers to the arrival time of the first path signal; the arrival time of the strongest power of the positioning signal refers to the signal arrival time with the highest power; the average arrival time of the signal refers to all The time after the acknowledgment signal is averaged, that is, the average time is related to the arrival time of all acknowledgment signals, which is a function of them; the arrival time width of the signal, that is, the difference between the arrival time of the last path and the arrival time of the first path It can also be the statistical standard deviation of the arrival time of each path. It is assumed that the arrival time of each path confirmed is (T1, T2, T3, ..., TN), and the corresponding received powers are (P1, P2, P3, ..., PN). The average arrival time of the signal is calculated as follows:

Method 1, T _mean = (T1 + T2 + T3 + ... + TN) / N;

Mode 2, (p1, p2, p3, ..., pN) = (P1, P2, P3, ..., PN) / (P1 + P2 + P3 + ... + PN);

T _mean =T1*p1+T2*p2+T3*p3+...+TN*pN;

In the above calculation, T _mean is the average arrival time of the signal, and other algorithms are not excluded.

The arrival time width of the signal has the following calculation method:

T _width =(T1-T _mean )*p1+(T2-T _mean )*p2+(T3-T _mean )*p3+...+(TN-T _mean )*pN;

In the above calculation, T _width is the arrival time _width of the signal, and other algorithms are not excluded.

The error in timing can be reported using the difference of the above time type parameters. The first time difference of arrival of the signal refers to the difference between the first arrival times of the different base stations and the reference base station; the difference in arrival time of the strongest power of the signal refers to the difference between the arrival times of the strongest powers of the signals of the base station and the reference base station.
