A method, system and device for establishing a communication link

Abstract

The invention discloses a method for establishing a communication link, comprising: a monitoring device collects an image within a preset range of the current orientation, and matches each terminal contained in the image with its corresponding identification (ID); according to the The image acquires all link information of each terminal; according to the all link information, the link information of the terminal and the peer terminal is sent to the corresponding terminal and the peer terminal. The invention also discloses a system and a device for establishing a communication link. By adopting the invention, the speed and precision of the terminal beam forming can be improved, and then the link establishment of the short-distance wireless communication can be completed quickly and accurately.

Description

technical field [0001] The present invention relates to short-distance wireless communication technology in the field of wireless communication, in particular to a method, system and device for establishing a communication link. Background technique [0002] 60GHz wireless communication technology is a short-distance wireless communication technology with transmission bandwidth and transmission rate reaching gigabit level, and its typical application scenarios are mainly indoors. Since the propagation of electromagnetic waves in the 60GHz frequency band shows light-like properties, that is, the propagation beam is very narrow and cannot penetrate obstacles, so the antennas in the 60GHz frequency band mostly use antenna arrays and beamforming technology to enable the beam to follow the specified direction along the line of sight or along the line of sight. The reflected path bypasses obstacles to reach the receiver. However, the above-mentioned beamforming technology require...

Problems solved by technology

[0004] 1. Use the Global Positioning System (GPS, Global Positioning System) module configured by the terminal itself to obtain location information and assist in beamforming. However, the positioning accuracy of the GPS module cannot meet the requirements for short-range wireless communication in an indoor environment. ;

[0005] 2. Apply low-frequency wireless fidelity (Wi-Fi, Wireless Fidelity) technology for positioning, but this method still can only achieve rough positioning accuracy;

[0006] 3. Assist the terminal to complete beamforming by pre-configuring the location information of the terminal. However, this method needs to reconfigure the location information when the terminal changes location, which is more complicated

[0007] It can be seen that in the short-distance wireless communication system of the prior art, fast and accurate beamforming between the receiving and receiving terminals cannot be realized, so the link establishment of the short-distance wireless communication cannot be completed quickly and accurately
