Problems solved by technology

Among them, the former uses communication satellites to perform real-time positioning around the world, and has high positioning accuracy, but requires the mobile terminal to have a GPS module; the latter does not require the mobile phone to have a GPS positioning module, but the positioning accuracy largely depends on the base station The distribution and the size of the coverage area, in some cases the error will be large
[0003] However, in many cases, the mobile terminal used by the user may neither have the conditions for GPS positioning nor the conditions for base station positioning
For example, devices such as laptops and tablets may not have a GPS module installed, or the GPS module may not work properly in some special environments (such as indoors), and such devices usually cannot directly access the mobile operator network like mobile phones , so the base station method cannot be used for positioning

Embodiment Construction

[0052] First, a method for positioning a mobile terminal provided by an embodiment of the present invention is described, and the method may include the following steps:

[0053] Obtain the identification information of the wireless network access point AP near the mobile terminal to be located;

[0054] According to the AP identification information, query the corresponding AP location information;

[0055] Determine the location of the mobile terminal to be located according to the queried AP location information.

[0056] The execution subject of the above steps may be a positioning device capable of communicating with the mobile terminal to be located, and the device may be located in the server device. The mobile terminal to be positioned in the above steps may be a mobile phone, a notebook computer, a tablet computer and other devices. These devices communicate with the positioning device through wired or wireless methods, and the server uses the wireless network acces...

Abstract

The invention discloses a mobile terminal positioning method and device. The mobile terminal positioning method comprises the following steps of: obtaining identification information of a wireless network access point (AP) near a mobile terminal to be positioned; searching corresponding AP position information according to the identification information of the AP; and determining a position of the mobile terminal to be positioned according to the searched AP position information. With the application of the technical scheme provided by the embodiment of the invention, the problem of positioning the mobile terminal without GPS (Global Position System) positioning and base station positioning conditions can be solved.

Description

technical field [0001] The present invention relates to the field of communication technology, in particular to a mobile terminal positioning method and device. Background technique [0002] Mobile terminal positioning refers to obtaining the location information (latitude and longitude coordinates) of the mobile terminal through a specific positioning technology. There are two traditional positioning technologies for mobile terminals: one is based on GPS, and the other is based on mobile base stations. Among them, the former uses communication satellites to perform real-time positioning around the world, and has high positioning accuracy, but requires the mobile terminal to have a GPS module; the latter does not require the mobile phone to have a GPS positioning module, but the positioning accuracy largely depends on the base station In some cases, the error will be very large. [0003] However, in many cases, the mobile terminal used by the user may neither have the cond...
