Method, device and system for determining affiliation area of mobile user

Abstract

The invention provides a method, a device and a system for determining a home area of a mobile user, and the method comprises the steps: obtaining a call record of the mobile user in a preset observation period; obtaining a base station cell and call duration corresponding to each call record according to the call records; carrying out discretization processing on the call duration to obtain a discrete time variable; establishing a spatial clustering model of the discrete time variables, and obtaining the most active position of the mobile user; and determining a home area of the mobile user according to a corresponding relationship between the most active position and a bottommost city area of an operator. Therefore, the purpose of determining the affiliation area through spatial clustering analysis of the activity degree position of the mobile user is achieved, the accuracy of the affiliation area determination result is improved, and a guarantee is provided for later customer maintenance and revenue improvement.

Description

technical field [0001] The present invention relates to the technical field of mobile communication, in particular to a method, device and system for determining the home area of ​​a mobile user. Background technique [0002] With the continuous expansion of the scale of mobile users, China's mobile service market has changed from an incremental market pattern to a stock market pattern. Studies have shown that the profit contributed by an old customer is 16 times that of a new customer, and the cost of acquiring a new customer is 5 times that of retaining an old customer. Therefore, making full use of existing resources and carrying out efficient customer retention and care activities for target customer groups is the focus of operators to ensure stable revenue growth. How to determine the belonging area of ​​the mobile user has become a key issue to improve service quality and accuracy. [0003] At present, the identification of the mobile user's attribution is usually on...

Problems solved by technology

[0004] However, the location of mobile service users is often uncertain, especially in large local networks. For example, customers may subscribe to mobile communication services in one place, but they are often active in another area

This method of determining the mobile user's belonging area only when the user newly joins the network greatly reduces the accuracy of the determination result and makes it difficult to maintain customers in the later period
