Ticket based method, device and system for determining activity range of mobile terminal

Abstract

The invention relates to ticket based method, device and system for determining the activity range of a mobile terminal. The method comprises the steps of: acquiring the electronic ticket data of the mobile terminal in a certain period and formatting the electronic ticket data; analyzing each call record in the formatted electronic ticket data to obtain all base stations, the number of times each base station appears and the longitude and the latitude of each base station in the call action records of a mobile subscriber; marking the geographic location of each base station to varying degrees in an electronic map according to the longitude and the latitude of each base station and different times each base station appears, and taking the marked range as the activity range of the mobile terminal. The invention determines the important activity places of the mobile terminal in the whole activity range on the basis of a call ticket, thereby providing great support for the investigation of criminal cases and saving a lot of resources.
