Method and apparatus of intelligent device to access wireless local area network

Abstract

The invention discloses a method and apparatus of an intelligent device to access a wireless local area network. The method comprises the following steps: sending detection request information by the intelligent device when the intelligent device needs to access the wireless local area network, wherein the detection request information contains an access request identifier used for indicating the absence of an access information mode and device information of the intelligent device; receiving detection response information by the intelligent device, analyzing encrypted access information from the detection response information, decrypting the encrypted access information by using a private key allocated to the intelligent device according to the device information of the intelligent device to obtain access information, and accessing the wireless local area network by using the access information. According to the method disclosed by the invention, a non-accessed device is helped by the device that has accessed the wireless local area network to access the wireless local area network, thereby effectively improving the network access efficiency of the device and solving the risk that the private information of the intelligent device is leaked to third party manufacturers.

Description

technical field [0001] The invention relates to the technical field of wireless communication of smart devices, in particular to a method and a device for smart devices to access a wireless local area network. Background technique [0002] Before accessing a WIFI network, a smart device with a WIFI (Wireless Fidelity) function needs to know the Service Set Identifier (SSID) and access password of an Access Point (AP for short). However, since many smart devices do not have a human-computer interaction interface, other devices with a human-computer interaction interface (such as mobile phones, PADs, computers, etc.) are needed to access the network of the AP. [0003] Joining the WIFI network needs to go through the process of scanning, authentication, association, identity verification, obtaining IP address and so on. A smart device with a WIFI function periodically sends a detection request message to scan for the existence of an AP, and the AP can notify the smart device ...

AI Technical Summary

Problems solved by technology

[0010] In the first method, multiple steps are required from the establishment of the connection to the disconnection between the home appliance and the mobile terminal, and after the configuration is completed, it is necessary to switch to the STA mode and then join the AP network, and the mobile terminal has been "disconnected" during this time state, bad user experience

[0011] In the second method, the efficiency of broadcast or multicast is low, and each frame carries very little information, and in the actual deployment network, packet loss often occurs, so the user experience is poor

[0012] In the third method, the biggest problem is that the router needs to obtain the key of the smart device. Most home appliances and routers are from different manufacturers, so there is a problem of leakage of private information of smart devices.
