Description
Technical field
The present invention relates to smart machine wireless communication technology fields more particularly to a kind of smart machine to access WLAN
Method and device.
Background technique
Smart machine with WIFI (Wireless Fidelity) function is needed to know and is connect before accessing WIFI network
The service set (Service Set Identifier, abbreviation SSID) and access of access point (Access Point, abbreviation AP)
Password.But due to many smart machines and without the interface of human-computer interaction, it is therefore desirable to there is human-computer interaction by other
The equipment (such as mobile phone, PAD, computer) at interface accesses the network of AP.
WIFI network needs are added to be scanned, authenticate, being associated with, authentication, obtaining the processes such as IP address and could complete.
Smart machine with WIFI function sends probe request message periodically to scan the presence of AP, and AP can then pass through spy
The relevant information of AP for surveying response message to inform smart machine.
Each smart machine with WIFI function has a device id, the device id may include manufacturer's information,
MAC Address, device model and unique sequence number etc..And each smart machine has a public private key pair, for encrypting
The data of transmission.
There is the method for the smart machine access WIFI network of WIFI function to include the following three types for configuration in the prior art:
Method one, the smart machine with WIFI function work under the mode of SOFTAP, access the intelligence by mobile terminal
Energy equipment, is allocated to smart machine for the SSID of AP and password.
Method two, mobile terminal period by way of broadcast or multicast, to send the SSID and password of AP, WIFI
Smart machine is in state of listening to, and obtains and parse SSID and password.
Method three, the smart machine with WIFI function Portable device model, router in probe response message receive
After will carry out equipment verification to cloud service, and obtain the public key of smart machine, and pass through public key and MAC Address export encryption
Code key, by the password of encryption code key encryption AP, (encryption SSID is optionally, because SSID can be obtained in Probe REQ
Take), smart machine is returned to by Probe RES.
Method in the prior art has the disadvantage in that
In method one, multiple steps are needed from establishing a connection to disconnect between household appliance and mobile terminal, and
It needs to switch to STA mode after the completion of configuration to add to AP network, and mobile terminal this period is constantly in " suspension " shape
State, user experience are bad.
In method two, the efficiency of broadcast or multicast is lower, and the information that each frame carries is considerably less, and in actual deployment net
In network, the phenomenon that often will appear packet loss, therefore user experience is poor.
In method three, the biggest problems are that router needs to obtain the key of smart machine, most of household appliance and
Router comes from different manufacturers, therefore the private information of smart machine has leakage.
