Embodiment Construction

[0021] In order to make the object, technical solution and advantages of the present invention clearer, various embodiments of the present invention will be described in detail below in conjunction with the accompanying drawings. However, those of ordinary skill in the art can understand that, in each implementation manner of the present invention, many technical details are provided for readers to better understand the present application. However, even without these technical details and various changes and modifications based on the following implementation modes, the technical solution claimed in each claim of the present application can be realized.

[0022] The first embodiment of the present invention relates to an automatic anti-theft alarm method for a terminal device. In this embodiment, it is necessary to pre-set the enabling condition of the anti-theft function of the terminal device, and the terminal device is in the anti-theft state when the enabling condition is...

Abstract

The invention relates to the file of communications, and discloses a terminal device automatic anti-theft alarm method and a terminal device. According to the invention, the terminal device will try to establish communication connection with an external tag by periodically utilizing the self-provided NFC function when being in the anti-theft state. If the establishment is failed continuously for many times, then a preset alarm ringtone will be played automatically. The communication connection established by utilizing the NFC function has a short distance limit, so once the distance between the terminal device and the external tag exceeds the distance limit, the establishment of the communication connection will be failed, and after the establishment of the communication connection is failed continuously for many times, the alarm function will be triggered automatically so as to achieved the mobile phone anti-theft purpose.

Description

technical field [0001] The invention relates to the communication field, in particular to the anti-theft technology of terminal equipment. Background technique [0002] With the increasing popularity of terminal devices such as mobile phones, more and more functions of the terminal devices are integrated and used. At present, Near Field Communication (NFC for short) technology has also begun to be widely used in mobile phones, and major mobile phone manufacturers have begun to add NFC functions to their latest released mobile phones. [0003] NFC is a short-range high-frequency wireless communication technology that allows non-contact point-to-point data transmission and exchange data between electronic devices (such as between mobile phones and external tags). This technology is powered by contactless RFID ( RFID ) evolved and is backward compatible with RFID. Like RFID, NFC information is also transmitted through electromagnetic induction coupling in the radio frequency...
