Embodiment Construction

[0038] The specific implementation of the present invention is as follows:

[0039] (1) Data collection: Using telecom operator signaling data, according to the track data of each IMSI identification number, collect and store the location of the base station where each IMSI is located and the time information of entering and leaving the cell.

[0040] The data used in the present invention comes from the signaling data of mobile operators, including: user mobile phone number-IMSI (International Mobile Subscriber Identification Number); location area identification code lac: used to identify different location areas; Base station number ci: combined with the location area identification code (lac), used to identify the cells covered in the network; the time when the IMSI entered the base station and the time when it left the base station;

[0041] (2) Data screening: read one IMSI pair each time, set as a IMSI and b IMSI, as the one-person-multiple-number pair to be determined; within...

Abstract

The invention provides a distance-based one-person multi-number mobile user identification method, which comprises the following steps of acquiring and storing the position of a base station where each IMSI (International Mobile Subscriber Identity) identification number is located and the time information of entering and exiting a community by utilizing signaling data of a telecom operator; reading one IMSI pair each time, and calculating the distance between every two IMSIs according to the longitude and latitude of the base station; converting the collected original signaling data into thedistance of the moving track according to the time sequence, determining the track similarity between the IMSI pairs according to the distance information, and determining the IMSI pairs which are judged to be the same track for more than a certain number of times in a certain time period as one person with multiple numbers.

Description

Technical field [0001] The present invention relates to the field of mobile communication technology, in particular to a method for identifying one-person multi-number users by using mobile communication big data. Background technique [0002] In view of the importance of statistical population information, many methods for indirect estimation of population information have been derived. For example, the change in the consumption of necessities in the area is used to estimate the population, such as the electricity consumption method, the water consumption method, and the salt sales method. The shortcomings of these methods are that the accuracy of the data obtained is not high, and there is a certain lag, the cost is relatively high, and the regional population data information cannot be quickly and accurately obtained. In addition, basic population censuses, population spot checks, and occasional thematic population surveys in a few provinces and cities are also methods of obt...
