Example one
As shown in fig. 1, an embodiment of the present invention provides a method for identifying a subway user, where the method includes:
and S110, obtaining the position information of the base station in the area along the subway.

Specifically, a subway line region is acquired from an official database in advance, then Measurement Report data (MR) of the subway line region is acquired in real time, namely intersection is obtained by crossing longitude and latitude ranges of the subway line region and longitude and latitude information of the MR data, then base station position information of the subway line region is reversely obtained according to the Measurement Report data, namely, duplication is removed according to preset base station position information of the MR data of the intersection portion, and base station position information of the subway line region is obtained.
And S120, acquiring the position time sequence information of the user.
In this embodiment, after the accurate base station location information is obtained, the location timing information of the user needs to be obtained, where the location timing information may be the base station location information obtained based on the communication signal of the mobile device of the user, and the mobile device of the user transmits the communication signal through the base station regardless of whether the user uses the mobile device, so that the base station that reports the communication signal of the mobile device of the user may be used as the location timing information of the user.
Preferably, the location timing information further includes reporting time of a communication signal of the mobile device of the user, and determining whether the reporting time is at operation time of a subway corresponding to the subway line region, and if the reporting time is not at the operation time of the subway, it may be directly determined that the user is a non-subway user without performing steps S130 and S140.
And S130, judging whether the position time sequence information is matched with the base station position information.
And S140, if the position time sequence information is matched with the base station position information, identifying the user as a subway user.
In this embodiment, after the accurate position timing information and the base station position information are obtained, it may be determined whether the position timing information matches the base station position information, specifically, the base station position information corresponds to the base station, that is, the base station position information includes the first base station, and the position timing information of the user is reported through the base station, that is, the position timing information includes the second base station, where the first base station and the second base station may be multiple, and then it is determined whether the position timing information matches the base station position information, that is, it is determined whether the first base station matches the second base station, specifically, it is determined whether the first base station includes the second base station, and if the first base station matches the second base station, the user is identified as a subway user. Because the number of the users can be multiple, all subway users can be accurately identified.
Illustratively, the method includes the steps of obtaining base station position information of a subway line area, wherein the base station position information includes 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 obtaining position time sequence information of a user, and because the base station A reports communication signals of mobile equipment of the user, the position time sequence information includes the base station A, matching is conducted, a first base station includes a second base station, namely matching is judged to be successful, and therefore the user is identified as a subway user.
The embodiment of the invention obtains the position information of the base station in the area along the subway line; acquiring position time sequence information of a user; judging whether the position time sequence information is matched with the base station position information; and if the position time sequence information is matched with the base station position information, the user is identified as the subway user, so that the problem that no identification method is available for the subway user is solved, and the effect of accurately identifying the subway user is realized.
Example two
As shown in fig. 2 to fig. 4, a second embodiment of the present invention provides a method for identifying a subway subscriber, and the second embodiment of the present invention further explains and explains the first embodiment of the present invention.
In this embodiment, as shown in fig. 2, on the basis of the first embodiment of the present invention, step S110 specifically includes:
s111, acquiring first longitude and latitude position information of the subway in the map and second longitude and latitude position information of a preset base station.
And S112, using the intersection base station position information of the first longitude and latitude position information and the second longitude and latitude position information as the first base station position information of the subway line area.
In this embodiment, the position information of the base station in the area along the subway can be obtained through the first longitude and latitude position information of the subway in the map and the second longitude and latitude position information of the preset base station. Specifically, when the data of the officer 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 a preset base station is obtained, wherein the preset base station is a base station which can be inquired. And then, the intersection base station position information of the first longitude and latitude position information and the second longitude and latitude position information is used as the first base station position information of the subway line area.
And S113, acquiring measurement report data of the area along the subway.
And S114, reversely obtaining the position information of the second base station in the area along the subway according to the measurement report data.
And S115, correcting the position information of the first base station by using the position information of the second base station to obtain the position information of the base station in the area along the subway.
In this embodiment, the first base station location information is only the base station location information of the area along the subway covered by the roughly defined wireless signal, and cannot be accurately identified, and the power of each base station is different, and the coverage area is also different according to the influence of a building or a shelter, but the first base station location information is very comprehensive, so that the accurate second base station location information is further obtained by obtaining MR data of the area along the subway, and the first base station location information is corrected by using the second base station location information, and finally the base station location information of the area along the subway is obtained.
Specifically, the position information of the first base station is comprehensive, the position information of the second base station is accurate, but the base stations in the area can be missed due to the fact that the area without MR data uploading, and therefore the position information of the first base station is gradually corrected by the position information of the second base station, so that the most accurate position information of the base stations in the area along the subway line can be obtained, and comprehensiveness and accuracy are both considered.
In this embodiment, as shown in fig. 3, on the basis of the first embodiment of the present invention, step S120 specifically includes:
s121, obtaining measurement report data and analysis data reported by deep packet analysis, wherein the analysis data comprises field information and reporting time.
And S122, identifying the user according to the field information.
In this embodiment, the location timing information of the user may be determined by obtaining all measurement report data (MR data) in the communication network and analysis data reported by Deep Packet analysis (DPI), specifically, the analysis 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 Identity), IMEI (International Mobile Equipment Identity), and each specific user may be identified by the field information such as IMSI, IMEI, and MSISDN.
And S123, associating the longitude and latitude position information of the measurement report data to the user through a position backfill algorithm to obtain the position track information of the user.
And 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 backfill algorithm to obtain the position track information of the user, and the position timing information of the user, that is, the longitude and latitude position information of the user at each time is obtained by combining the reporting time.
In this embodiment, as shown in fig. 4, on the basis of the first embodiment of the present invention, step S140 specifically includes:
and S141, if the position time sequence information is matched with the base station position information, 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 base station of the user passing through the subway line region 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 location timing information is longitude and latitude location information of a user at each time, the base station location information is longitude and latitude location information of a base station in the subway line region, the two longitude and latitude location information are matched, and if the difference between the longitude and latitude location information of each time and any longitude and latitude location information of the base station in the subway line region is smaller than a preset value within a preset time period, the location timing information is considered to be matched with the base station location information.
Further, since the average moving speed of subway users is generally about 40km/h, if the speed of the users is far away from the average moving speed, a part of non-subway users can be filtered out based on the average moving speed. Specifically, if the position timing information is matched with the base station position information, determining a first speed of the user within a preset time period according to the position timing information, then judging whether an absolute value of a difference value between the first speed and the preset speed is smaller than a first threshold, and if the absolute value of the difference value between the first speed and the preset speed is larger than the first threshold, determining that the user is a non-subway user.
Illustratively, the time sequence information is acquired according to the position of the user; the base station corresponding to the longitude and latitude position information of 11:40 is a base station A, the base station corresponding to the longitude and latitude position information of 12:40 is a base station B, and as the longitude and latitude position information of the base station in the subway line region is known, 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, and the absolute value of the difference value between the first speed and the preset speed is 30 which is greater than 20, so that the user is a non-subway user.
Further, even if the speed is consistent with the base station, the subway station may 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 is coincident with the subway, passengers on the train 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 a first threshold, a second sequential code of a base station of a user passing through a subway line area is acquired according to position time sequence information, the position information of the base station comprises the preset first sequential code, whether the matching rate of the first sequential code and the second sequential code is larger than a 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 a subway user.
Illustratively, the position information of a base station in a subway line area is obtained, and base stations corresponding to longitude and latitude position information in the position information of the base station are respectively as follows: the method comprises the following steps that a base station A, a base station B and a base station C are arranged in a subway line area, namely, the base station A, the base station B and the base station C are arranged in the subway line area, and then position time sequence information of a user is obtained, wherein the position time sequence information comprises the following steps: 11 point 12 points, longitude x1 latitude y 1; 12 o' clock, longitude x2 latitude y2, longitude x1 latitude y1 corresponding to the base station A, longitude x2 latitude y2 corresponding to the base station B, that is, the position timing information is matched with the base station position information, it is determined that the distance between the base station A and the base station B is 40km according to longitude x1 latitude y1 longitude and x2 latitude y2, the preset speed is 40km/h, so that the absolute value of the difference between the first speed and the preset speed of the user is less than a first threshold value, the sequence code of the known base station A is 1, the sequence code of the base station B is 2, the sequence code of the base station C is 3, the second sequence code is 12, and the preset first sequence code is 123, the same number of bits in the first sequence code as the second sequence code is taken only in sequence, the matching rate of the first sequence code and the second sequence code is 100%, and the second threshold value is 80%, that the matching rate of the first sequence code and the second sequence code is greater than the second threshold value, it is finally determined that the user is a subway user.
