Abstract

The present disclosure relates to a positioning method, device and system, and relates to the technical field of communication. The method of the present disclosure includes: acquiring at least three pieces of signal measurement information corresponding to multiple locations of the terminal; wherein, each piece of signal measurement information is the measurement information of signals interacted between different base stations and the terminal at corresponding location points; according to the inertia of the terminal Navigation data, determining the relative positional relationship of multiple location points; according to the relative positional relationship of multiple location points, mapping at least three pieces of signal measurement information corresponding to the terminal at multiple location points to at least three pieces of signal measurement information corresponding to one location point ; Determine the location information of the location point according to at least three pieces of signal measurement information corresponding to the terminal at the location point.

Description

technical field [0001] The present disclosure relates to the field of communication technologies, and in particular, to a positioning method, device, and system. Background technique [0002] Indoor positioning has a wide range of application scenarios, including indoor positioning applications such as shopping guide for shopping malls and exhibition halls, child positioning monitoring, car parking navigation, location search, and advertising. The current indoor positioning technology, network and terminal are immature, which affects the development of business. [0003] Currently, to perform high-precision positioning of a terminal by using an indoor base station, it is necessary to obtain more than three pieces of signal measurement information, for example, the terminal measures measurement information of signals of more than three base stations. SUMMARY OF THE INVENTION [0004] The inventor found that: in the existing indoor scene, generally only 1-2 pieces of signal...
