Description

Method and system for finding lost users

technical field

The invention belongs to the field of communication, and in particular relates to a method and system for finding a lost user.

Background technique

In recent years, with the vigorous development of the Internet financial industry, the proportion of non-performing assets has also increased rapidly, and the scale of non-performing assets in the entire industry has reached trillions of levels. This has also become a bottleneck restricting the business development of many P2P platforms. There are many reasons for the large number of non-performing loans. Many of them borrow from multiple sources and cannot repay when they are due, so they will choose to lose contact. For financial institutions, after losing contact, the biggest difficulty is to locate the borrower. Some people lost contact after changing their phone numbers and tried to disappear, which brought difficulties to asset collection.

Embodiments of the present invention provide a method for finding lost users, as shown in Figure 1, which includes:

S10. Obtain signaling data of the lost contact number.

Among them, the signaling data includes mobile subscriber identification number, location information and switch information.

S20. Search for a number that has the same signaling data as the lost number before the lost time time as the suspected number.

Since the signaling data of the two numbers in the dual-card mobile phone is the same, another number used by the lost user can be found according to the signaling data, so that the number can be locked as a suspect number.

S30. Obtain the signaling data of the suspect number after the disconnection time.

After the suspect number is determined, the signaling data of the suspect number after the time of losing contact is further obtained, so as to obtain the location of the lost user.

Another embodiment of the present invention also provides a method for finding a lost user, as shown in FIG. 2 , which specifically includes:

S1, to set the lost contact time of the lost contact number.

Wherein, the disconnection time is set by the user, and is usually the moment when the disconnection is determined.

S2. Obtain the mobile subscriber identification number, location information, and power on/off information of the lost number within a predetermined period of time before the lost contact time.

Wherein, the location information may be a location area code LAC.

S3. Search for a number that has the same mobile subscriber identification number, location information, and switch information as the lost number within a predetermined time period of the lost connection time as the suspected number.

The suspect number can be preliminarily locked through steps S1 to S3, but in practical applications, the signaling data of the suspect number is the same as that of the lost number, but the user of the suspect number and the lost user may not be the same person In order to further confirm that the user of the suspect number is the lost user, in this embodiment, steps S4 to S6 are also included.

S4. Obtain the mobile terminal identification number of the lost contact number.

S5. Obtain the mobile terminal identification number of the suspect number.

Among them, the mobile terminal identification number (IMEI) is equivalent to the ID card number of the mobile phone, and is used to identify each independent mobile phone.

S6, judging whether the mobile terminal identification number of the suspected number is the same as the mobile terminal identification number of the missing number, if they are the same, then go to step S7, if not, then end.

In this embodiment, by judging whether the mobile terminal identification number of the suspect number is the same as the mobile terminal identification number of the lost number before the time of losing contact, it is further determined whether the user of the suspect number is a lost user. If the mobile terminal identification number is the same as that of the lost number, it can be determined that the user of the suspect number and the lost number are the same person, that is, the lost user.

S7. Obtain the location information and power on/off information of the suspect number after the lost contact time.

By obtaining the location information of the suspect number after the time of losing contact, it can be used as an important clue to find the lost user.

It should be noted that, in this embodiment, in step S4 to step S6, it is judged whether the user of the suspected number and the lost number are the same person by judging whether the mobile terminal identification numbers of the suspected number and the lost number are the same, But the present invention is not limited thereto. In practical application, it is also judged whether the users of the suspect number and the lost number are the same person by judging whether the type allocation codes of the suspect number and the lost number are the same. Among them, the type allocation code can be used to determine whether the suspect number and the lost contact number are the same mobile phone.
