Problems solved by technology

Although this technology can guarantee the stability and security of communication through the protocol, it needs to establish a long-term connection process, which generally takes more than 5s.
In some fast and frequent connection and communication occasions, the bottleneck of the connection is often encountered, and the wifi router is often connected and disconnected for a long time, and the connection fails.

Embodiment 1

[0025] A kind of method utilizing wifi probe request and response packet to realize fast communication, comprises the following steps: at first based on the probe request and probe response message in wifi 802.11 protocol, the end that sends probe request message is defined as client end, sends probe One end of the response message is defined as the Master end,

[0026] Then, define the parameters of the Probe request message and the Probe response message,

[0027] Among them, IE1 needs to have the following parameters: packet type, packet number, packet index, IE2 number and packet mask;

[0028] IE2 needs to have the following parameters: data block offset, data block length and data block content;

[0029] IE1 packet types include the following definitions, 0: query request packet, 1: query response packet, 2: completion request packet, 3: completion response packet;

[0030] The number of packets is the total number of packets required to complete the data transmission;...

Abstract

The present invention relates to a method for realizing rapid communication by utilizing wifi probe request and response packets, which solves the deficiencies in the prior art. One end of the document is defined as the Client end, and the end that sends the probe response message is defined as the Master end. Then, parameters are defined for the Probe request message and the Probe response message. Among them, IE1 needs to have the following parameters: packet type, number of packets , packet index, number of IE2 and packet mask; IE2 needs to have the following parameters: data block offset, data block length and data block content; IE1 packet type includes the following definitions, 0: query request packet, 1: query response packet, 2 : Complete the request packet, 3: Complete the response packet; the client sends a request at a fixed frequency according to the packet receiving MASK, and the background continuously receives the Master’s response message and updates the packet receiving MASK until all packets are collected and sends a communication completion request to On the Master side, wait for the Master side to feedback the communication completion response.

Description

technical field [0001] The invention relates to a fast communication method, in particular to a method for realizing fast communication by utilizing wifi probe request and response packets. Background technique [0002] At present, to realize the communication between wifi data packets, the wifi device must first be connected to the wifi router, and then perform data communication and interaction through TCP / IP. To complete the connection of the wifi router, the wifi client must first listen to the wifi beacon data packet, or actively send the wifi probe request packet, and wait for the response of the AP to find the information of the wifi router; then complete the wifi connection through encrypted authentication and negotiation connect. The communication of TCP / IP protocol obtains the IP address through the application of DHCP dynamic IP, and then carries out the data communication of TCP / UDP based on the IP address. Although this technology can guarantee the stability a...
