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 termina

Embodiment 1

[0130] suppose to use Figure 4 In the short-distance wireless communication system shown, the method for establishing a communication link between the monitoring device and the terminal 1 is taken as an example to illustrate the present invention, and the specific process is as follows Figure 5 shown, including the following steps:

[0131] Step 501: Terminal 1 registers an ID.

[0132] Specifically, the terminal 1 can discover and join the system through its own low-frequency module, and register an ID, which is a unique identifier of the terminal in the system.

[0133] Step 502: The monitoring device collects an image within a preset range of the current orientation, and matches each terminal included in the image with its corresponding ID.

[0134] Specifically, when the preset range currently oriented by the monitoring device is the space where the terminal is located, the monitoring device captures an image of the space where the terminal is located, and collects ima...

Abstract

The invention discloses a method for establishing a communication link. The method includes the steps that images facing a preset range currently are acquired by a monitoring device and terminals and corresponding ID of the terminals are matched, wherein the terminals and the corresponding ID are contained in the images; all link information of the terminals is acquired according to the images; according to all the link information, link information of each terminal and link information of the corresponding opposite terminal are sent to the terminal and the corresponding opposite terminal. The invention further discloses a system and device for establishing the communication link. By the adoption of the method, system and device, the speed for beam forming of the terminals can be increased, the accuracy for beam forming of the terminals can be improved, and near field communication link establishment is rapidly and accurately finished.

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...
