Because the number of users can be multiple, all subway users can be accurately identified.
The method includes the steps that base station position information of a subway line area is obtained, the base station position information comprises a base station A, a base station B and a base station C, namely, three base stations of the base station A, the base station B and the base station C are arranged in the subway line area, then position time sequence information of a user is obtained, the base station A reports communication signals of mobile equipment of the user, the position time sequence information comprises the base station A, matching is conducted, a first base station comprises a second base station, namely, matching is judged to be successful, and therefore the user is identified as a subway user.

Example two
As shown in fig. 2-4, a second embodiment of the present invention provides a method for identifying subway users, and the second embodiment of the present invention is further explained based on the first embodiment of the present invention.
In this embodiment, as shown in fig. 2, based on the first embodiment of the present invention, step S110 specifically includes:
s111, acquiring first longitude and latitude position information of a subway and second longitude and latitude position information of a preset base station in a map.
S112, taking intersection base station position information of the first longitude and latitude position information and the second longitude and latitude position information as first base station position information of a subway line area.
In this embodiment, the base station position information of the subway along the area can be obtained through the first longitude and latitude position information of the subway and the second longitude and latitude position information of the preset base station in the map. Specifically, when the official data cannot be obtained, the first longitude and latitude position information of the subway can be obtained from the map, and the second longitude and latitude position information of the preset base station is obtained, wherein the preset base station is all the inquired base stations. And then taking intersection base station position information of the first longitude and latitude position information and the second longitude and latitude position information as first base station position information of the subway along the line area.
S113, acquiring measurement report data of the area along the subway.
And S114, reversely solving the second base station position information of the subway line area according to the measurement report data.
S115, correcting the first base station position information by using the second base station position information to obtain base station position information of the subway line area.
In this embodiment, the first base station position information is only the base station position information of the wireless signal approximately marked and covering the subway line area, and cannot be accurately identified, and the power of each base station is different, and the coverage area is different according to the influence of the building or the shielding object, but the first base station position information is very comprehensive, so that the accurate second base station position information is further obtained by acquiring the MR data of the subway line area, the second base station position information is used for correcting the first base station position information, and finally the base station position information of the subway line area is obtained.
Specifically, because the first base station position information is relatively comprehensive, the second base station position information is relatively accurate, but the region without MR data uploading can lead to missing the base station in the region, the second base station position information is used for gradually correcting the first base station position information, so that the most accurate base station position information of the subway along the region can be obtained, and the comprehensiveness and the accuracy are considered.
In this embodiment, as shown in fig. 3, based on the first embodiment of the present invention, step S120 specifically includes:
s121, acquiring measurement report data and analysis data of deep message analysis reporting, wherein the analysis data comprises field information and reporting time.
S122, identifying the user according to the field information.
In this embodiment, the location timing information of the user may be determined by acquiring all measurement report data (MR data) in the communication network and parsing data reported by deep packet inspection (DPI, deep Packet Inspection), and specifically, the parsing data reported by the DPI data includes field information and reporting time, where the field information may include field information such as IMSI (International Mobile Subscriber Identity ), MSISDN (Mobile Subscriber International ISDN/PSTN Number), IMEI (International Mobile Equipment Identity ), and the like, and each specific user may be identified by the field information such as IMSI, MSISDN, and IMEI.
S123, associating longitude and latitude position information of the measurement report data to the user through a position backfilling algorithm to obtain position track information of the user.
S124, obtaining the position time sequence information of the user according to the reporting time and the position track information.
In this embodiment, after a specific user is obtained, the longitude and latitude position information in the corresponding MR data is associated to the user through a position backfilling algorithm, so as to obtain position track information of the user, and position time sequence information of the user is obtained by combining the reporting time, namely, the longitude and latitude position information of each moment of the user.
In this embodiment, as shown in fig. 4, based on the first embodiment of the present invention, step S140 specifically includes:
s141, if the position time sequence information is matched with the position information of the base station, determining a first speed of the user in a preset time period according to the position time sequence information.
S142, judging whether the absolute value of the difference value between the first speed and the preset speed is smaller than a first threshold value.
S143, if the absolute value of the difference value between the first speed and the preset speed is smaller than a first threshold value, acquiring a second sequence code of the user passing through the base stations in the subway line area according to the position time sequence information.
S144, judging whether the matching rate of the first sequence coding and the second sequence coding is larger than a second threshold value.
S145, if the matching rate of the first sequence code and the second sequence code is larger than a second threshold value, identifying the user as a subway user.
In this embodiment, the position timing information is longitude and latitude position information of each moment of the user, the base station position information is longitude and latitude position information of a base station in a subway line area, the two longitude and latitude position information are matched, and if the difference value between the longitude and latitude position information of each moment of the user and any one longitude and latitude position information of the base station in the subway line area is smaller than a preset value in a preset time period, the position timing information is considered to be matched with the base station position information.
Further, since the average moving speed of subway users is generally around 40km/h, if the speed of users is far from that of users, a part of non-subway users can be filtered out based on the average moving speed. Specifically, if the position time sequence information is matched with the position information of the base station, determining a first speed of the user in a preset time period according to the position time sequence information, then judging whether the absolute value of the difference value between the first speed and the preset speed is smaller than a first threshold value, and if the absolute value of the difference value between the first speed and the preset speed is larger than the first threshold value, determining that the user is a non-subway user.
Illustratively, the position timing information of the user is obtained; the base station corresponding to the longitude and latitude position information of 11:40 is the base station A, the base station corresponding to the longitude and latitude position information of 12:40 is the base station B, and the distance between the base station A and the base station B can be obtained, for example, 10km, namely, the first speed of the user is 10km/h, the preset speed is 40km/h, the first threshold value is 20, the absolute value of the difference value between the first speed and the preset speed is 30 and is larger than 20, and therefore the user is a non-subway user.
Further, even if the speed and the base station coincide, it is possible to be a non-subway user because it is considered that the data reported by the subway user is not ideal continuous track point data, and when the urban road above the subway coincides with the subway, passengers on the vehicle are easily confused with passengers on the subway. Therefore, when the absolute value of the difference between the first speed and the preset speed is smaller than the first threshold, a second sequential code of the base station of the subway line area, which is the user passing through the subway line area, is acquired according to the position time sequence information, the position information of the base station comprises the preset first sequential code, then whether the matching rate of the first sequential code and the second sequential code is larger than the second threshold is judged, and if the matching rate of the first sequential code and the second sequential code is larger than the second threshold, the user is identified as the subway user.
Exemplary, base station position information of a subway line area is obtained, and base stations corresponding to longitude and latitude position information in the base station position information are respectively: base station A, base station B and base station C, namely there are three base stations of base station A, base station B and base station C in the area along the subway, then obtain the position time sequence information of the user, this position time sequence information includes: 11 points 12 minutes, longitude x1 latitude y1; the method comprises the steps that 12 points are 12 minutes, the longitude x2 latitude y2 is obtained, the base station corresponding to the longitude x1 latitude y1 is base station A, the base station corresponding to the longitude x2 latitude y2 is base station B, namely, the position time sequence information is matched with the position information of the base station, the distance between the base station A and the base station B is determined to be 40km according to the longitude x1 latitude 1 longitude and the longitude x2 latitude y2, the preset speed is 40km/h, therefore, the absolute value of the difference value between the first speed of a user and the preset speed is smaller than a first threshold value, the sequence code of the base station A is known to be 1, the sequence code of the base station B is 2, the sequence code of the base station C is 3, then the second sequence code is 12, the preset first sequence code is 123, the same digits as the second sequence code in the first sequence code are only sequentially obtained, the matching rate of the first sequence code and the second sequence code is 100%, the second threshold value is 80%, namely, the matching rate of the first sequence code and the second sequence code is larger than the second threshold value, and the user is finally determined to be the subway user.
