Step 103, AP sends the corresponding Beacon frame of each encryption algorithm type with broadcast mode.
The transmission sequence of Beacon frame is corresponded to according to scheduled encryption algorithm type, AP is sent when sending cycle reaches
The corresponding Beacon frame of one encryption algorithm type.For example, it is assumed that wireless service support encryption algorithm type be TKIP type,
1 type of AES-CCMP-SHA, 256 type of AES-CCMP-SHA, then AP periodically sends TKIP type pair with broadcast mode
The Beacon frame answered, the corresponding Beacon frame of 1 type of AES-CCMP-SHA, 256 type of AES-CCMP-SHA are corresponding
Beacon frame.
In the embodiment of the present invention, AP sends the process of the corresponding Beacon frame of each encryption algorithm type with broadcast mode,
It is specifically including but not limited to such as under type: corresponding to Beacon frame transmission sequence according to scheduled encryption algorithm type, AP is being sent
When period reaches, the corresponding Beacon frame of an encryption algorithm type is sent.For example, it is assumed that the Encryption Algorithm class that wireless service is supported
Type is TKIP type, 1 type of AES-CCMP-SHA, 256 type of AES-CCMP-SHA, and scheduled encryption algorithm type is corresponding
Beacon frame transmission sequence is that successively the corresponding Beacon frame of transmission TKIP type, 1 type of AES-CCMP-SHA are corresponding
The corresponding Beacon frame of Beacon frame, 256 type of AES-CCMP-SHA, then: when sending cycle reaches for the first time, AP is with wide
Broadcast mode sends the corresponding Beacon frame of TKIP type, and when sending cycle reaches for the second time, AP sends AES- with broadcast mode
The corresponding Beacon frame of 1 type of CCMP-SHA, when sending cycle third time reaches, AP sends AES-CCMP- with broadcast mode
The corresponding Beacon frame of 256 type of SHA, then in the 4th arrival of sending cycle, AP sends TKIP type pair with broadcast mode
The Beacon frame answered, and so on, subsequent Beacon frame transmission process no longer repeats in detail.
Since the STA1 encryption algorithm type supported is TKIP type, STA1 is receiving 1 type of AES-CCMP-SHA
When corresponding Beacon frame and the corresponding Beacon frame of 256 type of AES-CCMP-SHA, STA1 will abandon AES-CCMP-SHA 1
The corresponding Beacon frame of type and the corresponding Beacon frame of 256 type of AES-CCMP-SHA；STA1 is receiving TKIP type correspondence
Beacon frame when, STA1 can parse TKIP key information from Beacon frame, be based on this TKIP key information, STA1 with
Can be with interactive authentication message, association message between AP, and STA1 can establish connection with AP.Since the STA2 encryption supported is calculated
Method type is 1 type of AES-CCMP-SHA, therefore STA2 is receiving the corresponding Beacon frame of TKIP type and AES-CCMP-SHA
When the corresponding Beacon frame of 256 types, which will abandon the corresponding Beacon frame of the TKIP type and AES-CCMP-SHA
The corresponding Beacon frame of 256 types；For STA2 when receiving the corresponding Beacon frame of 1 type of AES-CCMP-SHA, STA2 can be from
1 key information of AES-CCMP-SHA is parsed in Beacon frame, is based on this 1 key information of AES-CCMP-SHA, STA2 and AP
Between can be with interactive authentication message, association message, and STA2 can establish connection with AP.The Encryption Algorithm supported due to STA3
Type is 256 type of AES-CCMP-SHA, therefore STA3 is receiving the corresponding Beacon frame of TKIP type and AES-CCMP-SHA
When the corresponding Beacon frame of 1 type, which will abandon the corresponding Beacon frame of TKIP type and 1 type of AES-CCMP-SHA
Corresponding Beacon frame；For STA3 when receiving the corresponding Beacon frame of 256 type of AES-CCMP-SHA, STA3 is from Beacon frame
In parse 256 key information of AES-CCMP-SHA, be based on 256 key information of AES-CCMP-SHA, can between STA3 and AP
With interactive authentication message, association message, STA3 can establish connection with AP.
Based on the above-mentioned technical proposal, corresponding by being generated for every kind of encryption algorithm type in the embodiment of the present invention
Beacon frame, and the corresponding Beacon frame of each encryption algorithm type is sent with broadcast mode, to make that various encryptions is supported to calculate
The STA of method type can correctly parse wireless service, and the encryption algorithm type supported using itself from Beacon frame
Access this wireless service.Further, aforesaid way can to support interactive authentication between the STA and AP of PMF wireless service
Message, association message, and STA and AP is made to establish connection；And aforesaid way is not it is also possible that support PMF wireless service
Interactive authentication message between STA and AP is associated with message, and STA and AP is made to establish connection.
