Since a terminal may include one or more IMEIs, at this time, the server can determine that the terminal corresponding to the first IMEI and the terminal corresponding to the second IMEI may for the same terminal.

S103. In a case where the trajectory similarity between the first IMEI and the second IMEI is greater than or equal to a similarity threshold, the server determines that the second IMEI belongs to the first terminal.

Wherein, the first terminal is a terminal corresponding to the first IMEI among the multiple terminals.

It should be understood that when the track similarity between the first IMEI and the second IMEI is greater than or equal to the similarity threshold, it means that the track similarity between the first IMEI and the second IMEI is relatively large, and the same terminal model corresponds to Among the two IMEIs, the number of locations where the first IMEI is located at multiple times is similar to the number of locations where the second IMEI is located at multiple times is relatively large. At this time, the server can determine The first IMEI and the second IMEI belong to the same terminal, and since the terminal corresponding to the first IMEI is the first terminal, the server can determine that the second IMEI also belongs to the first terminal.

It can be understood that when the track similarity between the first IMEI and the second IMEI is less than the similarity threshold, it means that the track similarity between the first IMEI and the second IMEI is small, and the same terminal model corresponds to Among the two IMEIs, the first IMEI is located at multiple locations at multiple times, and the number of locations similar to the second IMEI at multiple locations at multiple times is relatively small. At this time, the server can determine The first IMEI and the second IMEI belong to the same terminal,

The degree of similarity between the positions at a moment, when the trajectory similarity between the first IMEI and the second IMEI is greater than or equal to the similarity threshold, the server determines that the second IMEI belongs to the first terminal, the second IMEI belongs to the first terminal, the second IMEI The first terminal is a terminal corresponding to the first IMEI. In the present invention, since the first IMEI is the same as the first i characters of the second IMEI, the terminal model corresponding to the first IMEI is the same as the terminal model corresponding to the second IMEI, and the server is in the same terminal model. Among the IMEIs, when the first IMEI is located in multiple positions at multiple times and the second IMEI is located in multiple positions at multiple times, if the number of similar positions is relatively large, it is determined that the second IMEI is similar to the first IMEI The IMEI belongs to the same terminal, and it can be accurately determined that the data corresponding to the first IMEI and the data corresponding to the second IMEI are data of the same terminal, thereby improving the validity of terminal identification.

It can be understood that the plurality of cells includes a cell corresponding to each IMEI in the plurality of IMEIs at each moment in the plurality of moments.

It should be understood that when the first IMEI and the second IMEI correspond to the same cell at the same time, it means that the location of the terminal corresponding to the first IMEI and the location of the terminal corresponding to the second IMEI are both in the cell Within the coverage area, the location of the first IMEI is the same as that of the second IIMEI, or the distance between the location of the first IMEI and the location of the second IIMEI is relatively short.

It can be understood that when the value of the first number is larger, it means that the first IMEI corresponds to the same cell at the same moment more times within the preset time period, and the terminal corresponding to the first IMEI corresponds to the second IMEI The number of times that the terminal is located closer to each other at multiple moments is more, and when the first number is larger, the server may determine that the track of the first IMEI is more similar to the track of the second IMEI.

It should be understood that when the distance between the second cell and the first cell is less than or equal to the distance threshold, it means that the distance between the second cell and the first cell is relatively short. When the first IMEI corresponds to If the first cell is the first cell, and the second IMEI corresponds to the second cell at the first moment, it means that the distance between the terminal corresponding to the first IMEI and the terminal corresponding to the second IMEI is relatively short.

At this time, the server may determine that M is 4, N is 3, and the trajectory similarity is 75%.

In an optional implementation manner, a time interval can be understood as a time period, and the time period can be 24 hours (that is, one day), and the preset time period can include M time periods, and the server can determine the first The daily resident cell of the IMEI and the daily resident cell of the second IMEI, and the number of days on which the daily resident cell of the first IMEI and the daily resident cell of the second IMEI are the same are determined as trajectory similarity.

In conjunction with the description of the above embodiments, it should be understood that one IMEI corresponds to one SIM card at one time, and in an optional implementation, the preset time period also includes a target time, and the target time corresponds to the same SIM card. Specifically, between the target time, the IMEI corresponding to the SIM is the first IMEI, and after the target time, the IMEI corresponding to the SIM card is the second IMEI. At this time, the server can determine the first IMEI The resident cell corresponding to each of the multiple time intervals before the target time in the preset time period of the IMEI, and the multiple time intervals of the second IMEI in the preset time range before the target time The resident cell corresponding to each time interval, and then determine the target value. When the target value is greater than or equal to the value threshold, the server determines that the terminal corresponding to the SIM card remains unchanged, and determines that the SIM card is at the target time The card slot has been replaced.

Exemplarily, before the target time, the resident cell of the first SIM card is A at 8:00-12:00 every day, and B is the resident cell at 22:00-8:00 every day. After the time, the resident cell of 8:00-12:00 every day is A, and the resident cell of 22:00-8:00 every day is B. At this time, the server can determine that the SIM card has been replaced at the target time card slot, and determine that the first IMEI and the second IMEI belong to the same terminal.
