Abstract

Embodiments of the present invention disclose a wireless terminal positioning method and apparatus. The method comprises the steps of determining a direction vector corresponding to a target wireless terminal according to target wireless signals received by multiple front ends; acquiring a relative distance corresponding to the target wireless terminal; and determining absolute coordinates of the target wireless terminal according to the relative distance, the direction vector and preset base station coordinates. Through adoption of the wireless terminal positioning method and apparatus, when a mobile signal is poor, a stable positioning service is provided for the user, and the bandwidth use ratio of the wireless network channel and the throughput of the wireless device are improved.

Description

technical field [0001] Embodiments of the present invention relate to wireless communication technologies, and in particular, to a positioning method and device for a wireless terminal. Background technique [0002] With the development of wireless technology and the improvement of data processing capabilities, location-based services have become one of the most promising mobile Internet services. Whether it is about indoors or outdoors, the demand for quickly and accurately obtaining location information of wireless terminals and providing location services has become increasingly urgent. [0003] Currently, a positioning method for a wireless terminal mainly adopts a positioning technology based on a GPS (Global Positioning System, Global Positioning System). However, in crowded places, or places with poor mobile signals, such as in the field of public security, mineral resources development, tourism, etc., the use of GPS positioning technology will cause unstable positio...
