Wireless device and mobile terminal positioning method and system

Abstract

The invention provides a wireless device and a mobile terminal positioning method and system. The method comprises the following steps: the wireless device cross-validates the identities with a far-end mobile terminal through a secret key; the wireless device obtains location information of the far-end mobile terminal through an active query method or a passive receipt method; and the wireless device processes the location information and finally presents the processed location information to a user. Due to the adoption of the technical scheme of the invention, the user can visually view the location on which the far-end mobile terminal is located or historical track or other located statistical data by using the same wireless device.

Description

technical field [0001] The present invention relates to the technical field of communication, and more specifically, to a wireless device and a mobile terminal positioning method and system. Background technique [0002] With the development of wireless communication technology, in daily work and life, the application of portable mobile terminals represented by mobile phones is becoming more and more extensive. Most of these mobile terminals have a positioning service function, such as GPS (Global Positioning System, Global Positioning System) or A-GPS (Assisted GPS, assisted GPS) function, which brings a kind of active or passive positioning of these mobile terminal devices. , and then obtain the possibility of the current user's whereabouts of the mobile terminal. At present, there are three main methods for locating mobile terminal devices: [0003] One is to use the positioning service function of the mobile terminal to allow the user to check his own position on the m...

[0004] The second is to obtain the coordinates of the current base station of the mobile device or the location of the mobile device using the positioning service through background means such as system records on the side of the wireless network operator or the location service provider. This method is limited to the interior of the operator or service provider. Without the permission of the user of the mobile terminal device, the obtained data is unreliable, and it is inconvenient to open the obtained positioning data to third parties, and the scope of use is relatively small;

[0005] The third is based on some special military or civilian systems such as the Beidou satellite navigation system, with the help of a dedicated positioning terminal with a launch function, the positioning information of the mobile terminal is obtained in the system. This method is reliable and the data is relatively accurate, but the implementation is complicated. , the cost is high, and it cannot be connected with ordinary wireless networks;
