[0036] Figure 1 This is a flow chart of a terminal identification method provided by an embodiment of the present invention. This embodiment is applicable to the case of identifying a mobile terminal. The method can be executed by a terminal identification device. The terminal identification device can be implemented in the form of hardware and / or software. The terminal identification device can be configured in an electronic device such as a computer or a server. Figure 1 As shown, the method of this embodiment includes:

[0037] S110, obtaining a first communication base station position sequence of a mobile terminal using a first communication card within a target period in a target area, and a second communication base station position sequence of a mobile terminal using a second communication card.

[0038] Among them, the target area can be set according to actual needs. In an embodiment of the present invention, there are multiple mobile terminals that use communication cards for communication in the target area. The target time period can be set according to actual needs. In an embodiment of the invention, the time unit of the target time period can be at least one of year, month, day, hour, minute, etc. The first communication card and the second communication card can be understood as communication cards used by the mobile terminal for communication. In an embodiment of the present invention, the mobile terminal can be a smart watch, a mobile phone, a vehicle-mounted terminal device, etc. Optionally, the communication card can be a SIM card, an eSIM card, an iSIM card, etc. The first communication base station position sequence can be understood as a position sequence of base stations that provide network signals for mobile terminals using the first communication card within a target period in the target area. The second communication base station position sequence can be understood as a position sequence of base stations that provide network signals for mobile terminals using the second communication card within a target period in the target area. In an embodiment of the present invention, the base station position information in the first communication base station position sequence and the base station position information in the second communication base station position sequence can be the same or different. Optionally, the base station position information can be base station coordinates.

[0039] In the embodiment of the present invention, there are multiple ways to obtain the first communication base station position sequence of the mobile terminal using the first communication card in the target area during the target period. As an optional implementation in the embodiment of the present invention, the base station position information of the mobile terminal using the first communication card in the target area during the target period is obtained; and then the first communication base station position sequence of the mobile terminal using the first communication card in the target area during the target period can be obtained according to the acquisition time of the base station position information.

[0040] As another optional implementation of the embodiment of the present invention, obtaining the first communication base station position sequence of the mobile terminal using the first communication card in the target area during the target period may include: obtaining the identification sequence of the base station that provides the network signal to the mobile terminal using the first communication card in the target area during the target period, that is, obtaining the base station identification sequence; and then obtaining the communication base station position sequence of the mobile terminal using the first communication card in the target area during the target period based on the base station identification sequence, that is, the first communication base station position sequence. Among them, the base station identification sequence may include one or more base station identifications. It can be understood that the base station identification can be used to distinguish different base stations.

[0041] In an embodiment of the present invention, obtaining a communication base station position sequence of a mobile terminal using the first communication card in a target period in the target area based on a base station identification sequence may include: determining a correspondence between a base station identification and a base station position. Then, the base station position corresponding to each base station identification in the base station identification sequence may be determined in sequence. Then, a communication base station position sequence corresponding to the base station identification sequence may be obtained, that is, a communication base station position sequence of a mobile terminal using the first communication card in a target period in the target area may be obtained.

[0042] Similarly, in the embodiment of the present invention, there are multiple ways to obtain the second communication base station position sequence of the mobile terminal using the second communication card in the target area during the target period. As an optional implementation in the embodiment of the present invention, the base station position information of the mobile terminal using the second communication card in the target area during the target period is obtained; and then the second communication base station position sequence of the mobile terminal using the second communication card in the target area during the target period can be obtained according to the acquisition time of the base station position information.

[0043] As another optional implementation of the embodiment of the present invention, obtaining a second communication base station position sequence of a mobile terminal using a second communication card in a target area during a target period of time may include: obtaining an identification sequence of a base station that provides a network signal to a mobile terminal using a second communication card in a target area during a target period of time, i.e., obtaining a base station identification sequence; and then obtaining a communication base station position sequence of a mobile terminal using a second communication card in a target period of time in the target area based on the base station identification sequence, i.e., a second communication base station position sequence. The base station identification sequence may include one or more base station identifications. It is understandable that a base station identification may be used to distinguish different base stations.

[0044] In the embodiment of the present invention, obtaining the communication base station position sequence of the mobile terminal using the second communication card in the target area during the target period based on the base station identification sequence may include: determining the correspondence between the base station identification and the base station position. Then, the base station position corresponding to each base station identification in the base station identification sequence may be determined in turn. Then, the communication base station position sequence corresponding to the base station identification sequence may be obtained, that is, the communication base station position sequence of the mobile terminal using the second communication card in the target area during the target period may be obtained.

[0045] In an embodiment of the present invention, the number of mobile terminals using the device communication card in the target area within the target time period is multiple. Exemplarily, the mobile terminal using the device communication card may be a mobile phone terminal, and the target area may be observed in the administrative area dimension, such as a prefecture-level city or province level. In practical applications, the larger the target area, the better. Exemplarily, the target area may be city A, and the target time period may be a certain day. That is, the number of mobile phone terminals using the device communication card in city A within one day is multiple. The method of obtaining a first communication base station position sequence of mobile terminals using a first communication card within a target period in a target area, and a second communication base station position sequence of mobile terminals using a second communication card, may include: determining a first communication card and a second communication card among a plurality of device communication cards used within a target period in the target area, and obtaining first signaling data of the mobile terminal using the first communication card and second signaling data of the mobile terminal using the second communication card; obtaining a first communication base station position sequence of mobile terminals using the first communication card within the target period in the target area based on the communication base station position information in each of the first signaling data, and obtaining a second communication base station position sequence of mobile terminals using the second communication card within the target period in the target area based on the communication base station position information in each of the second signaling data.

[0046] Among them, the first communication card and the second communication card can be understood as two communication cards used in the target period in the target area. The first signaling data can be understood as the signaling data of the mobile terminal using the first communication card. The second signaling data can be understood as the signaling data of the mobile terminal using the second communication card. In an embodiment of the present invention, the first signaling data may include the location information of the base station that provides the network signal for the mobile terminal using the first communication card. The second signaling data may include the location information of the base station that provides the network signal for the mobile terminal using the second communication card. In an embodiment of the present invention, the signaling data may also include operator information, network standard, mobile phone number, device communication card number, communication base station identification, start time, end time, etc. The location information of the base station that provides the network signal for the mobile terminal using the first communication card in the signaling data is the communication base station location update data. Optionally, the location information of the base station that provides the network signal for the mobile terminal using the communication card may include the administrative area information, longitude information, latitude information, etc. of the base station.

[0047] In an embodiment of the present invention, in order to more accurately determine the number of mobile terminals used in the target area during the target period, the data of the communication base station switching "ABA" can be removed. "ABA" means that when the device is stationary or moving a short distance, the generated signaling data will still switch back and forth between communication base stations, where "A" and "B" can be two different communication base stations, and the user is actually stationary at "A". This situation will affect the accuracy of the actual trajectory of the device, so the latter two communication base station data can be removed, and only one communication base station data "A" is retained.

[0048] In an embodiment of the present invention, determining the first communication card and the second communication card from among the multiple device communication cards used in the target area during the target period may include: randomly selecting two communication cards from among the multiple device communication cards used in the target area during the target period, thereby obtaining the first communication card and the second communication card.

[0049] In an embodiment of the present invention, obtaining a first communication base station position sequence of a mobile terminal using the first communication card in the target period in the target area may include: obtaining first signaling data of the mobile terminal using the first communication card. In practical applications, the number of first signaling data of the mobile terminal using the first communication card may be one or more. In the case where the number of first signaling data of the mobile terminal using the first communication card is one, the communication base station position information in the first signaling data may be determined, so that the first communication base station position sequence of the mobile terminal using the first communication card in the target period in the target area may be obtained based on the communication base station position information. It can be understood that the first communication base station position sequence of the mobile terminal using the first communication card in the target period in the target area obtained is the communication base station position information in the first signaling data. In the case where the number of first signaling data of the mobile terminal using the first communication card is multiple, the communication base station position information in each of the first signaling data may be determined, so that the first communication base station position sequence of the mobile terminal using the first communication card in the target period in the target area may be obtained based on each of the communication base station position information, wherein each of the communication base station position information in the first communication base station position sequence may be arranged in sequence according to the generation time sequence of the first signaling data containing the communication base station position information.

[0050] Similarly, obtaining the second communication base station position sequence of the mobile terminal using the second communication card in the target period in the target area may include: obtaining the second signaling data of the mobile terminal using the second communication card. In practical applications, the number of the second signaling data of the mobile terminal using the second communication card may be one or more. In the case where the number of the second signaling data of the mobile terminal using the second communication card is one, the communication base station position information in the second signaling data may be determined, so that the second communication base station position sequence of the mobile terminal using the second communication card in the target period in the target area may be obtained based on the communication base station position information. It can be understood that the second communication base station position sequence of the mobile terminal using the second communication card in the target period in the target area obtained is the communication base station position information in the second signaling data. In the case where the number of the second signaling data of the mobile terminal using the second communication card is multiple, the communication base station position information in each of the second signaling data may be determined, so that the second communication base station position sequence of the mobile terminal using the second communication card in the target period in the target area may be obtained based on each of the communication base station position information, wherein the communication base station position information in the second communication base station position sequence may be arranged in sequence according to the generation time of the second signaling data containing the communication base station position information.

[0051] S120. Obtain first reference trajectory data of a mobile terminal using the first communication card according to the first communication base station position sequence, and obtain second reference trajectory data of a mobile terminal using the second communication card according to the second communication base station position sequence.

[0052] The first reference trajectory data may be understood as the reference trajectory data of the mobile terminal using the first communication card obtained according to the first communication base station position sequence. The second reference trajectory data may be understood as the reference trajectory data of the mobile terminal using the second communication card obtained according to the second communication base station position sequence.

[0053] In an embodiment of the present invention, the first communication base station position sequence includes the position information of one or more base stations that provide network signals to the mobile terminal using the first communication card. In practical applications, the first communication base station position sequence usually includes the position information of multiple base stations that provide network signals to the mobile terminal using the first communication card. The position information of each base station can be spliced ​​in sequence according to the sequence of base stations that provide network signals to the mobile terminal using the first communication card, so as to obtain the first reference trajectory data of the mobile terminal using the first communication card. It can be understood that the first communication base station position sequence includes the position information of a base station that provides network signals to the mobile terminal using the first communication card. The first reference trajectory data is the position information of the base station that provides network signals to the mobile terminal using the first communication card.

[0054] Similarly, in an embodiment of the present invention, the second communication base station position sequence includes the location information of one or more base stations that provide network signals to the mobile terminal using the second communication card. In practical applications, the second communication base station position sequence usually includes the location information of multiple base stations that provide network signals to the mobile terminal using the second communication card. The location information of each base station can be spliced ​​in sequence according to the order of the base stations that provide network signals to the mobile terminal using the second communication card, so as to obtain the second reference trajectory data of the mobile terminal using the second communication card. It can be understood that the second communication base station position sequence includes the location information of a base station that provides network signals to the mobile terminal using the second communication card. The second reference trajectory data is the location information of the base station that provides network signals to the mobile terminal using the second communication card.

[0055] S130. Obtain first target trajectory data of a mobile terminal using the first communication card in the target area within the target time period based on the first reference trajectory data, and obtain second target trajectory data of a mobile terminal using the second communication card in the target area within the target time period based on the second reference trajectory data.

[0056] The first target trajectory data may be trajectory data obtained according to the first reference trajectory data, and the second target trajectory data may be trajectory data obtained according to the second reference trajectory data.

[0057] In an embodiment of the present invention, obtaining the first target trajectory data of the mobile terminal using the first communication card within the target time period in the target area based on the first reference trajectory data may include: first determining a plurality of geospatial grids corresponding to the target area, wherein the geospatial grid may be a hexagonal grid. Afterwards, each reference trajectory point in the first reference trajectory data may be mapped to the geospatial grid of the target area, respectively. Thus, based on the mapping result of the geospatial grid, the first target trajectory data of the mobile terminal using the first communication card within the target time period in the target area may be obtained. At this time, the first target trajectory data may be grid trajectory data. Grid trajectory data may be understood as trajectory data represented in the form of a grid to indicate that the trajectory data has been mapped into a grid.

[0058] Similarly, obtaining the second target trajectory data of the mobile terminal using the second communication card in the target period in the target area based on the second reference trajectory data may include: determining a plurality of geospatial grids corresponding to the target area, wherein the geospatial grids are hexagonal grids; mapping each reference trajectory point in the second reference trajectory data to the geospatial grids of the target area; and obtaining the second target trajectory data of the mobile terminal using the second communication card in the target period in the target area based on the mapping results of the geospatial grids. Similarly, the second target trajectory data may be grid trajectory data.

[0059] In an embodiment of the present invention, the hexagonal geospatial grid can be obtained by using Uber H3 technology to divide the geographic space of the target area, thereby obtaining multiple geospatial grids corresponding to the target area. In an embodiment of the present invention, the determination of multiple geospatial grids corresponding to the target area can include: performing H3 grid division and encoding on the geographic information of the target area according to the set H3 spatial index level to obtain a grid set of the target area under the H3 spatial index level, wherein the grid set can include multiple geospatial grids corresponding to the target area.

[0060] In an embodiment of the present invention, the hexagonal geographic space grid obtained by using the Uber H3 technology can more accurately obtain the target trajectory data of the mobile terminal using the communication card, so as to more accurately determine whether the mobile terminals using different communication cards are the same mobile terminal, and then determine the communication card included in the mobile terminal. In an embodiment of the present invention, since the communication card uses a mobile network (also known as a cellular network), the signal coverage of each communication base station that constitutes the network coverage is hexagonal, so that the entire network is named like a honeycomb, and each hexagon can be used as a base station. The UberH3 grid is in the shape of a honeycomb. In an embodiment of the present invention, the Uber H3 grid is used to express the base station coverage, which can accurately map the target trajectory of the mobile terminal. Figure 2 Schematic diagram of a base station cell is shown. In practical applications, the base station coverage is usually within 1.5km, so the cell size of the geospatial grid can be set to 1.5km, which is equivalent to 7 levels of Uber H3.

[0061] S140. Determine, based on the first target trajectory data and the second target trajectory data, whether the mobile terminal using the first communication card and the mobile terminal using the second communication card within the target time period in the target area are the same mobile terminal.

[0062] Specifically, a preset similarity comparison algorithm, such as the Jaccard similarity coefficient, can be used to compare the first target trajectory data and the second target trajectory data for similarity, thereby obtaining a similarity comparison result. When the similarity comparison result exceeds the preset similarity threshold, it can be determined that the mobile terminal using the first communication card and the mobile terminal using the second communication card in the target time period in the target area are the same mobile terminal. When the similarity comparison result does not exceed the preset similarity threshold, it can be determined that the mobile terminal using the first communication card and the mobile terminal using the second communication card in the target time period in the target area are not the same mobile terminal. Among them, the preset similarity threshold can be set according to actual needs, which is not specifically limited here, for example, 0.9, 0.95, 0.97, etc.

[0063] It should be noted that, when it is determined that the mobile terminal using the first communication card and the mobile terminal using the second communication card are the same mobile terminal, it can be determined that the first communication card and the second communication card belong to the communication card of the same mobile terminal. In this technical solution, by comparing whether the mobile terminals using different communication cards are the same mobile terminal, the number of mobile terminals used in the target area during the target period can be determined, so as to more accurately determine the target object flow and / or the number of target objects in the target area during the target period. Among them, the target object can be a user.

[0064] The technical solution of the embodiment of the present invention is to obtain the first communication base station position sequence of the mobile terminal using the first communication card in the target period in the target area, and the second communication base station position sequence of the mobile terminal using the second communication card; obtain the first reference trajectory data of the mobile terminal using the first communication card according to the first communication base station position sequence, and obtain the second reference trajectory data of the mobile terminal using the second communication card according to the second communication base station position sequence; obtain the first target trajectory data of the mobile terminal using the first communication card in the target period in the target area based on the first reference trajectory data, and obtain the second target trajectory data of the mobile terminal using the second communication card in the target period in the target area based on the second reference trajectory data; determine whether the mobile terminal using the first communication card and the mobile terminal using the second communication card in the target period in the target area are the same mobile terminal based on the first target trajectory data and the second target trajectory data. The technical solution of the embodiment of the present invention realizes a more accurate determination of whether mobile terminals using different communication cards are the same mobile terminal.

Among them, the technical features that are the same or similar to those in the aforementioned embodiments are not repeated here.

[0066] like Figure 3 As shown, the method of this embodiment specifically includes:

Obtain first target trajectory data of a mobile terminal using the first communication card within the target period in the target area based on the first reference trajectory data; obtain second target trajectory data of a mobile terminal using the second communication card within the target period in the target area based on the second reference trajectory data.

[0070] S240: Perform trajectory segmentation on the first target trajectory data and the second target trajectory data to obtain multiple pairs of trajectory segments, wherein each pair of trajectory segments includes a first trajectory segment in the first target trajectory data and a second trajectory segment in the second target trajectory data, and the first trajectory segment corresponds to the second trajectory segment.

[0071] The trajectory segment may include a first trajectory segment in the first target trajectory data and a second trajectory segment in the second target trajectory data, and the first trajectory segment corresponds to the second trajectory segment. The first trajectory segment may be a trajectory segment obtained by segmenting the trajectory of the first target.
