That is, each set of set reference point sequences includes a plurality of set reference points set along the corresponding set traffic route stations, the set reference points including base stations and possibly wireless access points (AP, wireless Access Point). The set traffic route includes at least one of a high-speed route and a rail traffic route. The rail transit line includes at least one of a subway line, a high-speed rail line, and a light rail line. In practical application, in the case that the traffic line is a subway line, as shown in fig. 2 and 3, the set reference points are set along the subway rail, the number of the set reference points set near the rail between two subway stations is determined by the length of the subway rail and the wireless environment in the subway channel, and the radio frequency fingerprint information of every two adjacent set reference points in each set of set reference point sequences has obvious difference.
When the traffic line is set to be a highway, under the condition that a highway usually comprises two lanes with different driving directions at the same time, a set of set reference point sequences corresponding to each highway comprises a set reference point sequence; in the case that a highway generally includes only one lane in the traveling direction, two set reference point sequences are included in a set of set reference point sequences corresponding to each highway; when the traffic route is set to be a track traffic route, because the running tracks corresponding to different running directions are different, a set of set reference point sequences corresponding to each track traffic route comprises two set reference point sequences, and each set reference point sequence corresponds to one running direction of the track traffic route.
In practical application, the electronic equipment acquires first radio frequency fingerprint information acquired by the terminal, and determines a set reference point passed by the terminal from at least one set of set reference point sequences based on the first radio frequency fingerprint information acquired by the terminal and second radio frequency fingerprint information corresponding to the set reference point.
In order to reduce the power consumption of the electronic device, in some embodiments, the first radio frequency fingerprint information acquired by the terminal is acquired when the terminal enters a set traffic line.
When the electronic equipment is a terminal in actual application, the terminal acquires first radio frequency fingerprint information under the condition that the terminal detects that the electronic equipment enters a set traffic line currently; when the electronic equipment is a server, the server acquires first radio frequency fingerprint information acquired by the terminal under the condition that the terminal is detected to enter a set traffic line.

The riding application can be a quick application without installation or an application needing installation.
It should be noted that, the mode of detecting whether the terminal enters the set traffic line is not limited to the above three modes, and whether the terminal enters the set traffic line can be determined by other modes of detecting whether the terminal enters the station.
Based on the first radio frequency fingerprint information acquired by the terminal and the second radio frequency fingerprint information corresponding to the set reference point, the implementation process of determining the set reference point passed by the terminal from at least one set of set reference point sequences is as follows:
in some embodiments, when the electronic device acquires the first rf fingerprint information acquired by the terminal, the electronic device determines a set reference point corresponding to each piece of first rf fingerprint information, so as to obtain each set reference point passed by the terminal, thereby obtaining all set reference points passed by the terminal: and determining second radio frequency fingerprint information which is most matched with the first radio frequency fingerprint information based on the first radio frequency fingerprint information acquired by the terminal and second radio frequency fingerprint information corresponding to a set reference point in at least one set of set reference point sequences, and determining the set reference point corresponding to the determined most matched second radio frequency fingerprint information as the set reference point through which the terminal passes.
In some embodiments, the electronic device may also determine the set reference point through which the terminal passes by: determining a set traffic line of the terminal, and determining at least one set of set reference point sequences corresponding to the set traffic line of the terminal from at least one set of set reference point sequences; and determining a set reference point passed by the terminal based on the first radio frequency fingerprint information acquired by the terminal and based on the second radio frequency fingerprint information corresponding to the set reference point in the determined at least one set of set reference point sequences. The set reference point sequence corresponding to the set traffic line where the terminal is located comprises: the terminal comprises a set reference point sequence corresponding to a first set traffic line where the terminal is located and a set reference point sequence corresponding to a second set traffic line containing stations on the first set traffic line where the terminal is located. The electronic equipment determines the set traffic line where the terminal is located by any one of the following modes:
Determining a site where the terminal is located based on the first positioning information of the terminal and the second positioning information of each site on the set traffic line, and determining the set traffic line where the site where the terminal is located is the set traffic line where the terminal is located;
and determining the set traffic line of the site where the terminal is located as the set traffic line of the terminal based on the first radio frequency fingerprint information acquired by the terminal and the radio frequency fingerprint information corresponding to each site on the set traffic line.
In some embodiments, under the condition that at least one set of set reference point sequences corresponding to the set traffic line where the terminal is located is determined, the electronic device determines a set reference point through which the terminal passes for the first time based on the first radio frequency fingerprint information acquired by the terminal and based on the determined second radio frequency fingerprint information corresponding to the set reference point in the at least one set of set reference point sequences; detecting whether the terminal is out of the station, determining the station of the terminal out of the station under the condition of detecting the terminal out of the station, and determining all the set reference points passed by the terminal based on at least one set of set reference point sequences corresponding to the set traffic line where the terminal is located, the set reference points passed by the terminal for the first time and the set reference points corresponding to the station of the terminal out of the station. In practical applications, the terminal can be determined to be inbound or outbound by monitoring the set application.
In some embodiments, the terminal detects whether the terminal is outbound through the setting application, when the terminal detects that the terminal is outbound, the terminal stops collecting the radio frequency fingerprint information, and the electronic device may determine, based on the radio frequency fingerprint information last collected by the terminal and based on the second radio frequency fingerprint information of the set reference point in at least one set of set reference point sequences corresponding to the set traffic line where the terminal is located, a set reference point last passed by the terminal from at least one set of set reference point sequences corresponding to the set traffic line where the terminal is located; the electronic device may determine all the set reference points passed by the terminal from at least one set of set reference point sequences corresponding to the set traffic line in which the terminal is located, based on the set reference point passed by the terminal for the first time and the set reference point passed by the terminal for the last time.
In order to reduce the amount of calculation and improve the efficiency of determining the reference point passed by the terminal, in some embodiments, the determining, based on the first rf fingerprint information acquired by the terminal and the second rf fingerprint information corresponding to the set reference point, the set reference point passed by the terminal from at least one set of set reference point sequences includes:
Determining a first set reference point matched with the current position of the terminal based on the first radio frequency fingerprint information acquired by the terminal and the second radio frequency fingerprint information corresponding to each set reference point;
determining at least one set of first set reference point sequences from the at least one set of set reference point sequences; the first set reference point sequence is a set reference point sequence containing the first set reference point;
and determining a set reference point passed by the terminal from at least one set of first set reference point sequences.
Here, the current position of the terminal characterizes a position where the terminal is located when the terminal collects the first radio frequency fingerprint information.
The electronic equipment determines the similarity between the first radio frequency fingerprint information acquired by the terminal and the second radio frequency fingerprint information corresponding to each set reference point, and determines the set reference point corresponding to the second radio frequency fingerprint information which is most similar to the first radio frequency fingerprint information as a first set reference point matched with the current position of the terminal; at least one set of first set reference point sequences including the first set reference points are determined from at least one set of set reference point sequences, and the set reference points passed by the terminal are determined from at least one set of first set reference point sequences.
It should be noted that, in the case that the current position of the terminal corresponds to the transfer station on the set traffic line, the number of groups of the first set reference point sequence including the first set reference point is at least two; and under the condition that the current position of the terminal corresponds to the non-transfer station on the set traffic line, the group number of the first set reference point sequence containing the first set reference point is 1. As shown in fig. 3, when the determined first set reference point is the reference point a, the first set reference point sequence including the first set reference point represents a set of first set reference point sequences corresponding to the set traffic route formed by the station 1, the station 2, and the station 3, and the set of first set reference point sequences includes 2 first set reference point sequences. When the determined first set reference point is the reference point C, the number of groups of the first set reference point sequences including the first set reference point is 2, that is, the first set reference point sequence includes a group of first set reference point sequences corresponding to the set traffic lines formed by the station 1, the station 2 and the station 3, and a group of first set reference point sequences corresponding to the set traffic lines formed by the station 4, the station 2 and the station 5, where the first set reference point sequence includes 4 set reference point sequences.
In practical application, when the set of first set reference point sequences include 2 set reference point sequences and the set reference point passed by the terminal is determined from at least one set of first set reference point sequences, the electronic device may determine the set reference point sequence in which the first set reference point is located from at least one set of first set reference point sequences, and determine the set reference point passed by the terminal from the set reference point sequences in which the first set reference point is located. Wherein,,
the electronic equipment detects whether the terminal is out of the station under the condition that at least one group of first set reference point sequences are determined, determines the station of the terminal out of the station under the condition that the terminal is detected to be out of the station, and determines the reference point through which the terminal passes based on all the determined first set reference point sequences, the determined first reference points and the set reference points corresponding to the station of the terminal out of the station.
In some embodiments, considering that the terminal stops acquiring the rf fingerprint information when the terminal is out of the station, at this time, the electronic device may determine, from the set reference point sequence in which the first set reference point is located, the set reference point that the terminal passes through last time, based on the rf fingerprint information acquired last time by the terminal and based on the second rf fingerprint information of the set reference point in the set reference point sequence in which the first set reference point is located; and determining all the set reference points passed by the terminal based on the determined all the first set reference points, the determined all the first set reference point sequences and the set reference points passed by the terminal last time.
In order to more quickly determine the set reference point that the terminal passes through, and improve the efficiency of determining the travel track of the terminal, in some embodiments, when determining the set reference point that the terminal passes through from at least one set of first set reference point sequences, the method includes:
matching third radio frequency fingerprint information acquired by the terminal with second radio frequency fingerprint information corresponding to at least one second set reference point; the collection time corresponding to the third radio frequency fingerprint information is later than the collection time corresponding to the first radio frequency fingerprint information; the second set reference point is a set reference point adjacent to the first set reference point in the at least one set of first set reference point sequences;
determining a third set reference point as a set reference point through which the terminal passes; the third set reference point is a second set reference point which is the most matched between the corresponding second radio frequency fingerprint information in the at least one second set reference point and the third radio frequency fingerprint information.
Here, since the set reference point sequence is composed of a plurality of set reference points arranged according to the position information, when determining at least one set of first set reference point sequences, the electronic device may determine a set reference point adjacent to the first set reference point from at least one set of first set reference point sequences, and determine all the determined set reference points adjacent to the first set reference point as the second set reference point; matching the third radio frequency fingerprint information acquired by the terminal with the second radio frequency fingerprint information corresponding to each second set reference point to obtain a matching result; and determining a third set reference point corresponding to the second radio frequency fingerprint information which is most matched with the third radio frequency fingerprint information from the determined second set reference points based on the matching result, and determining the third set reference point as a set reference point through which the terminal passes. Wherein,,
The second set reference point characterizes the next set reference point that the terminal may pass after passing the first set reference point, that is, the second set reference point is an alternative reference point. As shown in fig. 3, when the determined first set reference point is the reference point a, the second set reference point is the reference point B and the reference point C; when the determined first set reference point is the reference point C, the second set reference point comprises a reference point A, a reference point D, a reference point E, a reference point F and a reference point G.
In addition, when the third set reference point is determined, the third set reference point may be determined as a first set reference point matching the position of the terminal, so as to determine a new second set reference point based on the new first set reference point, and determine a new third set reference point based on the new second set reference point.
In this embodiment, after determining at least one set of first set reference point sequences, the electronic device determines at least one second set reference point from the at least one set of first set reference point sequences, so as to obtain a next set reference point that the terminal may pass through, matches the third rf fingerprint information with the second rf fingerprint information corresponding to the second set reference point, instead of matching the third rf fingerprint information with the second rf fingerprint information corresponding to all the set reference points included in the at least one set of first set reference point sequences, so that the calculation amount can be reduced, and thus the time required for determining the next set reference point that the terminal passes through is reduced, and the set reference point that the terminal passes through can be determined more quickly.
To determine the second set point of reference more quickly, in some embodiments, the method further comprises, based on determining the second set point of reference:
determining the traveling direction of the terminal based on the determined set reference point through which the terminal passes;
and determining the second set reference point from set reference points adjacent to the first set reference point in the at least one set of first set reference point sequences based on the traveling direction of the terminal.
The electronic equipment determines a set reference point adjacent to the first set reference point from at least one set of first set reference point sequences under the condition that the at least one set of first set reference point sequences are determined; determining the traveling direction of the terminal based on the determined set reference point passed by the terminal and the position of the terminal in the corresponding set reference point sequence; and determining a second set reference point from the determined set reference points adjacent to the first set reference point based on the traveling direction of the terminal. As shown in fig. 3, in the case where the determined set reference point through which the terminal passes includes a reference point a and a reference point B, the traveling direction of the terminal is from station 1 to station 2, i.e., from left to right; under the condition that the first set reference point currently determined by the electronic equipment is a reference point A, the second set reference point is a reference point C; and under the condition that the first set reference point currently determined by the electronic equipment is the reference point C, the second set reference point comprises the reference point D, the reference point E, the reference point F and the reference point G.
In some embodiments, the method further comprises:
the set reference point passed by the terminal is determined by the following method:
determining the similarity between the radio frequency fingerprint information collected by the terminal and the second radio frequency fingerprint information corresponding to the set reference point;
determining a fourth set reference point as a set reference point through which the terminal passes; the fourth set reference point represents a set reference point corresponding to the second radio frequency fingerprint information corresponding to the determined maximum similarity; the maximum similarity is greater than a first set threshold.
The electronic device determines the similarity between the radio frequency fingerprint information collected by the terminal and the second radio frequency fingerprint information corresponding to the set reference point, determines the maximum similarity of which the similarity is larger than the first set threshold, determines the set reference point corresponding to the second radio frequency fingerprint information corresponding to the maximum similarity as a fourth set reference point, and determines the fourth set reference point as a set reference point through which the terminal passes.
In practical application, the radio frequency fingerprint information acquired by the terminal and the second radio frequency fingerprint information acquired by the electronic equipment comprise multiple radio frequency fingerprint information. The similarity of at least one item of radio frequency fingerprint information between every two adjacent set reference points in each set of set reference point sequences is smaller than a second set threshold value, so that the radio frequency fingerprint information of every two adjacent set reference points in each set of set reference point sequences has obvious difference, and the set reference points passed by the terminal can be accurately determined.
In practical application, under the condition that the radio frequency fingerprint information comprises a plurality of items of radio frequency fingerprint information, when the electronic equipment calculates the similarity between the radio frequency fingerprint information acquired by the terminal and the second radio frequency fingerprint information, the quotient of the number of items of the matched radio frequency fingerprint information and the total number of items of the radio frequency fingerprint information can be determined as the corresponding similarity. Of course, the electronic device may also determine the similarity between the radio frequency fingerprint information collected by the terminal and the second radio frequency fingerprint information by using other manners, for example, convert the radio frequency fingerprint information collected by the terminal and the second radio frequency fingerprint information into vectors respectively, calculate cosine similarity between the vectors, and obtain the similarity between the radio frequency fingerprint information collected by the terminal and the second radio frequency fingerprint information.
In practical application, the radio frequency fingerprint information at least includes the radio frequency fingerprint information of the serving cell and the radio frequency fingerprint information of the neighboring cell, and may also include the radio frequency fingerprint information of the AP. Wherein,,
the serving cell and the neighbor cell may be cells in at least one of the following mobile communication technologies: third generation mobile communication technology (3G,3rd generation wireless systems), fourth generation mobile communication technology (4G,4th generation wireless systems), and fifth generation mobile communication technology (5G,5th generation wireless systems).
The radio frequency fingerprint information of the serving cell and the radio frequency fingerprint information of the neighbor cell at least comprise the following four items:
cell frequency point number (ARFCN, absolute Radio Frequency Channel Number);
cell number (CID, cell Id);
cell Physical number (PCI); and
reference signal received power (RSRP, reference Signal Receiving Power) of the cell.
In practice, the electronic device identifies the cell by ARFCN, CID, and PCI. When the electronic equipment calculates the similarity between the radio frequency fingerprint information collected by the terminal and the second radio frequency fingerprint information, under the condition that ARFCN, CID and PCI in the radio frequency fingerprint information collected by the terminal are the same as ARFCN, CID and PCI in the second radio frequency fingerprint information, the corresponding similarity is determined based on the difference between RSRP in the radio frequency fingerprint information collected by the terminal and RSRP in the second radio frequency fingerprint information. The smaller the difference, the higher the similarity. In practical application, the similarity corresponding to the RSRP difference value can be determined based on the setting range of the RSRP difference value and based on the setting corresponding relation between the setting range and the similarity.
The radio fingerprint information of the AP includes a basic service set identifier (BSSID, basic Service Set Identifier).
The radio frequency fingerprint information of the serving cell and the radio frequency fingerprint information of the neighboring cell may further include at least one of:
mobile country code (MCC, mobile Country Code);
mobile network code (MNC, mobile Network Code);
cell broadband (Bandwidth);
cell synchronization signal block index (SSB index, synchronization Signal and PBCH block index) of 5G.
In practical application, the similarity of at least one item of radio frequency fingerprint information between every two adjacent set reference points in each set of set reference point sequences is smaller than a second set threshold value, so that the radio frequency fingerprint information of every two adjacent set reference points in each set reference point sequence has obvious difference.
For example, the PCIs of cells in the radio frequency fingerprint information of each two adjacent set reference points are different, or the PCIs are the same but the RSRP difference is larger, for example, the RSRP difference is larger than 10db. In practical application, the second set threshold may be smaller than or equal to the first set threshold.
Step 102: and determining the travel track of the terminal based on the determined position information corresponding to the set reference point.
Here, the database stores second radio frequency fingerprint information and corresponding location information of each set reference point in the set reference point sequence, the location information representing a geographical location of the set reference point.
Under the condition that the set reference point passed by the terminal is determined, the electronic equipment acquires position information corresponding to the set reference point passed by the terminal from a database; and the electronic equipment connects all the determined set reference points according to the position information based on the position information corresponding to each set reference point in all the determined set reference points passed by the terminal, so as to obtain the travel track of the terminal.
