Method for the automatic device discovery in the wireless interconnection

Abstract

The disclosed automatic detection method for wireless interconnection device comprises: adding field for device source independently for Beacon frame, Probe response frame, Association Request frame and Reassociation Request frame, all in MAC layer of BSS network; AP builds and maintains said source information, broadcasts periodically the source through Beacon frame; when scanning network, the new device analyzes information field of Beacon frame and Probe response frame to obtain the source condition and decide whether detecting device and provide basis for register; according to scan result, the new device selects AP and sends Association Request frame to the AP, joins network, and registers device or source. This invention improves system search performance, and reduces the implementation cost.

Description

technical field [0001] The present invention relates to a method for wireless connection of equipment, in particular to a method for automatic discovery of equipment in wireless interconnection. Background technique [0002] The concept of "wireless interconnection" was first proposed by IT enterprises, mainly referring to the wireless connection of network communication. With the development of the integration trend of 3C (home appliances, communications, computers), the interconnection between household electrical appliances has become the focus of attention of major enterprises, and is known as one of the future development directions of the home appliance industry. Technicians envision connecting the various electronics and appliances in the home so that they can communicate with each other. At the same time, the wireless interconnection between various devices makes the home no longer full of wires and boxes, and the living environment will become more comfortable. ...

AI Technical Summary

Problems solved by technology

[0009] 1. The IGRS standard device discovery protocol is an application layer protocol based on the transport layer protocol, which requires the device to have strong protocol processing capabilities, thus increasing the cost of the device;

[0010] 2. The device discovery protocol of the IGRS standard does not specify the specific implementation of the physical layer, that is, it does not specify the link between two devices, such as wired, Bluetooth or 802.11 wireless LAN

This approach increases the detection time and reduces the detection performance, making it difficult to realize automatic detection and automatic linking;

[0012] 4. The device discovery protocol of the IGRS standard is based on the computer and is oriented to home applications. It has a complex structure and is not suitable for mobile applications.
