Embodiment Construction

[0055] In order to solve the technical problem of low accuracy of wireless positioning technology in the prior art, the embodiment of the present invention provides a positioning method, device and system, a positioning signal determination method and a terminal. Detailed description. It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention.

[0056] In this example, a positioning method and a positioning signal determination method are proposed. The positioning signal is a signal carrying a time parameter, and the existing time difference of arrival (TDOA) method is improved, so that it can be determined with a small error rate The location of the terminal.

[0057] The above terminals can be mobile terminals, such as mobile phones, tablet computers and other terminal devices with smart modules, or portable devices, such as smart watches, etc. can be used as terminals, and the posi...

Abstract

The invention discloses a positioning method, device and system, a positioning signal determination method and a terminal, wherein the positioning method includes: acquiring a positioning signal of a terminal to be positioned, wherein the positioning signal includes: a time parameter; according to the positioning The signal is used to locate the terminal to be located. The invention effectively solves the technical problem of low positioning accuracy in the prior art, and achieves the technical effect of effectively improving the positioning accuracy.

Description

technical field [0001] The present invention relates to the field of mobile communication, in particular to a positioning method, device and system, a positioning signal determination method and a terminal. Background technique [0002] With the continuous development of GPS (Global Positioning System, Global Positioning System) positioning technology, GPS positioning technology is widely used in fields such as medical care, industry, public safety, logistics supply, and transportation. Especially in the field of mobile terminals (for example: mobile phones), the GPS function has become a core function module. [0003] At present, wireless positioning usually uses satellites and base stations for terminal positioning. For example, the position of the mobile terminal can be calculated by using a triangular formula estimation algorithm according to the distance between the terminal and the base station. However, due to shielding or reflection of electromagnetic waves by urban...
