Method and theftproof system of mobile terminal based on blue tooth submachine

Abstract

The invention is applied to the mobile communication field, which provides an anti-theft method of a mobile terminal end on the basis of a blue tooth sub machine, wherein the method comprises following steps: detecting strength of radiofrequency signals which are transmitted by an end to end, calculating a strength changing rate of the radiofrequency signals, and regulating the interval of the communication time of both communication sides according to the change rate of the radiofrequency signals which are obtained through calculating. The invention also provides an anti-theft system of a mobile terminal end on the basis of a blue tooth sub machine, wherein strength of radiofrequency signals which are transmitted by an end to end can be realized to detect and the strength change rate of the radiofrequency signals is calculated through arranging an arithmetic unit for the strength change rate of the radiofrequency signals and a regulating unit for communication time interval on the mobile terminal end and the blue tooth sub machine, therefore the interval of the communication time between both communication sides is self-adapted and regulated according to the strength change rate of the radiofrequency signals, thereby frequent communications which are unnecessary between both communication sides can be avoided, and the anti-theft system not only reduces power consumption of the system, but also provides effective stolen protection for the mobile terminal end.

Description

technical field [0001] The invention belongs to the field of mobile communication, and in particular relates to a mobile terminal anti-theft system and method based on a bluetooth handset. Background technique [0002] Bluetooth is a technical specification for short-range wireless communication. Its original goal is to replace the existing wired cable connections on various digital devices such as handheld computers and mobile phones. Judging from the current application, due to the small size, low power and good anti-interference of Bluetooth technology-based devices, its application is not limited to computer peripherals, and can be integrated into almost any digital device, especially those that are sensitive to data. Mobile devices and portable devices with low transmission rate requirements, for example, PDA (Personal Digital Assistant, personal digital assistant). [0003] With the advent of "information explosion" in the information age, mobile terminals, such as PD...
