Mobile networking method and system with minimum interference

Abstract

The invention provides a mobile networking method and device with minimum interference. The mobile networking method comprises the following steps: an unmanned aerial vehicle establishes connection and communication with a ground base station through a wireless relay way; the unmanned aerial vehicles are connected and communicated through a wireless networking way; multiple unmanned aerial vehicles cooperatively form a cellular network to provide the wireless network service for a user; each unmanned aerial vehicle receives receiving signal intensity information returned by user equipment, and measures beam arrival angle information of a user equipment signal; by use of a mobile interference alignment and beam forming method, the signal main lobe is aligned with a wave incoming direction of a service user, the nulling is aligned with the wave incoming direction of an interference signal, thereby finding an optimal hovering position. The mobile networking method provided by the invention has the advantages that the interference between adjacent cells is reduced through the mobility of the unmanned aerial vehicle sub-base station, the existing wireless network equipment is mainly utilized, professional equipment is unnecessary to install, and the extremely high universal applicability is provided.

Description

technical field [0001] The present invention relates to the technical field of wireless communication, in particular to a mobile networking method and system for minimizing interference. Background technique [0002] With the continuous development of wireless communication technologies, there are more and more wireless network devices, so the number of wireless access points also increases. In 3G and 4G, the coverage area of ​​the cell becomes smaller and the number of base stations increases, making the edge of the cell blurred. At the same time, the high spectrum reuse factor inevitably brings serious inter-cell interference. How to effectively cover the service area while reducing interference and provide high-quality communication services is the focus of wireless network service providers. In the existing networking method, the cell base station is usually located at a fixed location, and when the number of users in the cell increases, the interference also increases,...

AI Technical Summary

Problems solved by technology

In the existing networking method, the base station of the cell is usually located in a fixed position. When the number of users in the cell increases, the interference also increases, resulting in a decrease in the communication quality of users in the cell.

[0003] The traditional networking method has the problem of high interference in the case of high user density, and the base station cannot be moved
