Positioning method and system of communication network

Abstract

The embodiment of the invention provides a positioning method and system of a communication network. The method comprises the steps of: determining one or more than one first base by a server; sendinga distance measurement request wireless frame to the second high-frequency distance measurement module of the terminal by the one or more than one first base through the first high-frequency distancemeasurement module itself; sending a distance measurement response wireless frame for the distance measurement request wireless frame to the first high-frequency distance measurement module of the one or more than one first base by the terminal through the second high-frequency distance measurement module itself; calculating the distance information of the one or more than one first base and theterminal by adopting the distance measurement response wireless frame by the one or more than one first base through the first high-frequency distance measurement module itself, and sending the distance information to the server; adopting the distance information of each first base and the terminal by the server to calculate the position of the terminal. According to the embodiment of the invention, the positioning accuracy can be improved by adopting the method for positioning through the high-frequency distance measurement module.

Description

technical field [0001] The present application relates to the technical field of communications, and in particular to a positioning method for a communication network and a positioning system for a communication network. Background technique [0002] The Internet of Things technology is the third information technology revolution after computers and the Internet. It has the advantages of real-time and interactivity, and has been widely used in many fields such as urban management, digital home, positioning and navigation, logistics management, and security systems. Among them, LoRa is an ultra-long-distance transmission scheme based on spread spectrum technology in the Internet of Things, which has the characteristics of long transmission distance, low power consumption, multi-node and low cost. [0003] Positioning is an important application of the LoRa network. However, the current positioning solutions on the market are not only expensive, but also have low positioning ...

AI Technical Summary

Problems solved by technology

However, the current positioning solutions on the market are not only expensive, but also have low positioning accuracy (above 70 meters)

This has led to the delay in putting the LoRa network positioning function into practical use.
