Abstract

The invention relates to a method and a system for discovering a user residence position based on mobile phone signaling. The method comprises the following steps: the obtained mobile phone signalingdata of the user is taken as the original trajectory data, and the original trajectory data is sequentially processed by data cleaning, data slicing, preliminary clustering, data verification and corecluster calculation, and finally the user staying position is obtained. Adopting a series of algorithms such as track slice aggregation, hierarchical clustering algorithm, kernel density clustering algorithm and machine learning algorithm, etc., considering mobile phone track point density, signaling time interval, track point moving direction and moving distance, etc., we can judge user 's staying position, staying time, entering and leaving staying point time. The algorithm can effectively eliminate the interference of base station drift on user location judgment, improve the identificationaccuracy of user dwell point position and dwell time, and objectively restore the user dwell position.

Description

technical field [0001] The invention relates to the field of mobile phone signaling data, in particular to a method and system for discovering a user's staying position based on mobile phone signaling. Background technique [0002] At present, there are two main technical approaches to discover the user's staying location based on mobile phone signaling: [0003] 1. According to the fixed space unit, the cumulative length of stay of the user in the area is counted, the geometric center of the calculation area is the stay position, and the first and last trajectory time is the start and end time of this stay. [0004] 2. Based on the traditional spatial data clustering algorithm, the neighborhood search is performed according to a certain radius, and the data satisfying this range are aggregated into one category. When the aggregated data accumulation time exceeds a certain threshold, it is judged that the category is a stay group, and the group geometry is removed. The cent...
