Method and apparatus for protecting user intimacy by fuzzy mobile phone position

Abstract

The invention relates to a method for protecting user privacy by a vague mobile phone position, which has the following steps that: A. a timer T0 is started; B. the information of adjacent cells around a base station which mobile phone is in, is achieved; C. an enterable cell list is established; the number of the cell in the list is N; D. if T0 reaches a cycle T or the enterable cell list is changed, the step E is entered; E. a cell M be activated next is randomly selected in the enterable cell list; F. if the mobile phone is in a connected state, the mobile phone is repositioned in the cell M through a switching process and the timer T0 is reset; if the mobile phone is in a standby state, the mobile phone is repositioned in the cell M through cell reselection and the timer T0 is reset. A device suitable for the method comprises a control module, a timer module, an adjacent cell searching module, a judging and sequencing module, a random number generation module and a standard protocol stack module. The invention uses a cell switching method by the mobile phone to make the information of the mobile phone position in vagueness, thereby achieving the aim of preventing accurate position by the network.

Description

technical field [0001] The invention relates to a method and device for protecting user privacy in a mobile communication system, in particular to a method and device for protecting user privacy by blurring mobile phone location information. Background technique [0002] With the development of wireless communication technology, while people's life has become more and more convenient, due to technical defects, personal privacy protection is also facing more and more serious challenges. The location information of the mobile phone, as an important private information of the mobile phone user, marks the current geographic location of the user. At present, according to whether or not mobile phones are required to participate, positioning technologies for mobile phones are mainly divided into two types: mobile positioning technologies that require mobile phones to report information and mobile phone positioning technologies that do not require mobile phones to report information...
