Embodiment Construction

[0055] In order to solve the technical problem of low accuracy of wireless positioning technology in the prior art, embodiments of the present invention provide a positioning method, device and system, positioning signal determination method, and terminal. The following describes the present invention with reference to the accompanying drawings and embodiments. Detailed description. It should be understood that the specific embodiments described here are only used to explain the present invention, but do not 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 that carries time parameters. The existing time difference of arrival (TDOA) method is improved, so that the error rate can be determined with a small error rate. The location of the terminal.

[0057] The above-mentioned terminal may be a mobile terminal, such as a mobile phone, a tablet computer, and other ...

Abstract

The invention discloses a positioning method, device and system, a positioning signal determining method, and a terminal. The positioning method comprises the steps: obtaining a positioning signal ofa to-be-positioned terminal, wherein the positioning signal comprises a time parameter; and carrying out the positioning of the to-be-positioned terminal according to the positioning signal. Accordingto the invention, the method effectively solves a technical problem that the positioning precision is low in the prior art, and achieves the effective improving of the positioning precision.

Description

Technical field [0001] The present invention relates to the field of mobile communications, in particular to a positioning method, device and system, positioning signal determination method and 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 medical, industrial, public safety, logistics, and transportation fields. Especially in the field of mobile terminals (for example, mobile phones), the GPS function has become a core functional module. [0003] Currently, 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 the shielding or reflection of electromagnetic waves by urban buildings, etc., it is...
