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, often encounter connection bottlenecks, and often encounter wifi routers that are connected, disconnected, and fail to connect for a long time

Embodiment 1

[0025] A method for realizing fast communication using wifi probe request and response packets, including the following steps: First, based on the probe request and probe response messages in the wifi 802.11 protocol, the end that sends the probe request message is defined as the client end, and the probe is sent One end of the response message is defined as the Master end,

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

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

[0028] IE1 package type includes the following definitions, 0: query request package, 1: query response package, 2: completion request package, 3: completion response package;

[0029] The number of packets is the total number of packets required to complete the data transmission;

[0...

Abstract

The invention relates to a method of using a wifi probe request and a response packet to realize rapid communication, and solves the insufficiency in prior art. The technical scheme comprises the steps of defining one end for sending probe request as the Client end, and defining one end for sending probe response as the Master end based on probe request and probe response in wifi 802.11 protocol; then, defining parameters to the Probe request and Probe response, wherein, IE1 needs the following parameters: packet type, packet number, packet index, IE 2 number and packet mask; IE2 needs the following parameters: data block offset, data block length and data block content; IE1 packet type comprises the following definition: 0 for querying request packet; 1 for querying response packet; 2 for completing the request packet; and 3 for completing the response packet. The Client end sends a request at a fixed frequency based on a received packet MASK; a background receives response of the Master continuously and updates the received packet MASK until all packets collected and a communication complete request is sent to the Master end; and the Master end gives a communication complete response feedback.

Description

Technical field [0001] The invention relates to a method for fast communication, in particular to a method for realizing fast communication by using wifi probe request and response packets. Background technique [0002] At present, to realize the communication between wifi data packets, the wifi device must first connect to the wifi router, and then perform data communication and interaction through TCP / IP. To complete the connection to the wifi router, the wifi client must first monitor 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 pass encryption authentication and negotiation to complete the wifi connection. For TCP / IP protocol communication, an IP address is obtained through DHCP dynamic IP application, and then TCP / UDP data communication is performed based on the IP address. Although this technology can guarantee the stability and security of communication th...
