Problems solved by technology

In indoor dense urban areas, due to the large attenuation of the GPS signal, it is impossible to search for enough 4 stars, and the GPS positioning cannot be completed, which restricts the positioning function
[0004] The main problem of traditional wireless positioning schemes is that there are too few options for positioning anchor points, and they are limited to public anchor points, such as satellite base stations, etc.
In addition, factors such as NLOS, multipath, and channel environment changes indoors will also lead to inaccurate cellular positioning. Although there have been some research results in this area, they are generally based on ideal assumptions, and further research is needed to make it feasible in practical applications. technical solutions

Embodiment Construction

[0042] The preferred embodiments of the present invention will be described in detail below in conjunction with the accompanying drawings. It should be understood that the preferred embodiments described below are only used to illustrate and explain the present invention, and are not intended to limit the present invention.

[0043] image 3 It is a flow chart of terminal-assisted wireless positioning provided by an embodiment of the present invention, such as image 3 As shown, the steps include:

[0044] In step 301, the first terminal UE cannot be positioned successfully, and it is used as an assisted positioning requesting terminal.

[0045] The first terminal determines whether its positioning condition is satisfied, and if it is satisfied, it performs positioning; if it is not satisfied, it acts as an auxiliary positioning requesting terminal. Specifically, the positioning conditions specifically include but are not limited to: whether the number of signals received fr...

Abstract

The invention discloses a terminal-assisted wireless positioning method and device, which relate to the field of wireless communication. The device includes: a request sending module, which is used to send a request to the vicinity of the first terminal when the first terminal to which it belongs does not have the positioning capability. At least one second terminal that has completed positioning initiates an assisted positioning request, and saves the sending time of the assisted positioning request; the response receiving module is configured to receive assisted positioning information sent by the second terminal in response to the assisted positioning request, and The receiving time of the auxiliary positioning information is saved; the positioning calculation module is used to determine its spatial position by using the auxiliary positioning information and receiving time, and the sending time of the auxiliary positioning request. The present invention assists terminals without positioning capability to complete wireless positioning through mutual cooperation among terminals.

Description

technical field [0001] The invention relates to the field of wireless communication, in particular to a wireless communication positioning technology. Background technique [0002] With the continuous development of the times, mobile phone positioning technology has received more and more attention. Whether it is GPS positioning technology, or the use of wireless sensor networks or other positioning means for positioning, there are limitations. In order to achieve higher positioning accuracy, multiple positioning systems cooperate and combine positioning, that is, multi-mode positioning. range for seamless, precise positioning. For example, the organic combination of satellite positioning system and mobile communication system for mobile phone positioning, make full use of the advantages of satellite positioning system in large coverage area, high positioning accuracy in open areas and mobile communication network in indoor and dense urban areas, to better meet the market...
