Embodiment Construction

[0050] The invention provides a method for switching mobile phone device numbers to protect user privacy, which is used in the mobile phone positioning process. Such as image 3 Shown, the inventive method comprises the following steps:

[0051] A: When the mobile phone is turned on, use its pre-stored N IMSI numbers to register with the network and access the mobile network. N is a positive integer greater than or equal to 2;

[0052] B: Waiting for the network call or the user's initiative to call, the mobile phone uses one of the IMSI numbers selected by the user (for the mobile phone caller) or the network selection (for the mobile phone called) to establish a communication link and use it first;

[0053] C: The mobile phone starts the timer Timer;

[0054] D: If the timer reaches the set time T0, proceed to step E; otherwise, proceed to step D;

[0055] E: The phone randomly selects an unused IMSI number;

[0056] F: The mobile phone uses the IMSI number selected in s...

Abstract

The invention provides a method for protecting privacy of the user by switching a cell phone equipment number. The applied cell phone is composed of an IMSI management module, a dispatching control module and an original cell phone module. The invention carries out random selection between different cell phone equipment numbers through the cell phone, and improves the possibility that the user is searched by a network under the condition of guaranteeing the normal work of the cell phone; besides, due to continuous switching of the equipment number, the privacy of the user is effectively protected.

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 for protecting user privacy by switching mobile phone device numbers and a mobile phone implementing the method. 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. [0003] At present, according to whether mobile phones are required to actively participate in the classification, mobile phone positioning technologies are mainly divided into two types: mobile phone positioning technologies that require mobile phones to report information and mobile phone positioning technol...
