Problems solved by technology

[0002] As the number of smart home devices used in the home increases, the networking of smart homes becomes more and more complex
Most of the networking technologies proposed in related technologies are based on the IEEE802.15.4 protocol, such as the standard networking of Zigbee, etc. For low-power devices such as SUB-1G or RF433MHZ, simple key interactions are generally used, which are vulnerable to external interference and encryption during the period. key theft
[0003] However, SUB-1G or RF433MHZ is a narrow-band small wireless transmission. When sending and receiving data packets physically, there will be a large number of data packet collisions, which will lead to the failure of sending and receiving.
Especially when a large number of SUB-1G or RF433MHZ devices enter the network and interact, the command packets and response packets will seriously congest the channel

Abstract

The invention provides a network access method, device and system. The method comprises the following steps: sending a network access broadcast packet through a current working channel; receiving a network access request from a to-be-accessed device, wherein the network access request is sent by the to-be-accessed device after the to-be-accessed device receives the network access broadcast packetin a rapid network access mode; if the device information of the device to be accessed carried by the network access request is checked to be in a local list to be added, sending a channel negotiationpacket encrypted by the device information to the device to be accessed, wherein the channel negotiation packet carries the channel information of the optimal channel decided by the gateway device; and when the current working channel is not the optimal channel, switching the current working channel to the optimal channel, and negotiating a communication key with the device to be accessed to thenetwork through the switched optimal channel, the communication key being used by the gateway device and the device to be accessed to the network to complete network access of the device to be accessed to the network. According to the embodiment, the networking speed can be increased, and the networking safety can be guaranteed.

Description

technical field [0001] The present application relates to the technical field of network processing, and in particular to a method, device and system for network access. Background technique [0002] As the number of smart home devices used in the home increases, the networking of the smart home becomes more and more complex. Most of the networking technologies proposed in related technologies are based on the IEEE802.15.4 protocol, such as the standard networking of Zigbee, etc. For low-power devices such as SUB-1G or RF433MHZ, simple key interactions are generally used, which are vulnerable to external interference and encryption during the period. key theft. [0003] However, SUB-1G or RF433MHZ is a kind of narrow-band wireless transmission. When sending and receiving data packets physically, there will be a large number of data packet collisions, which will lead to the failure of sending and receiving. Especially when a large number of SUB-1G or RF433MHZ devices enter ...
