Embodiment 1
[0108] An embodiment of the present invention provides a method for accessing a wireless local area network, specifically as figure 1 As shown, the method includes:
[0109] 101. The wireless access point AP receives a probe request message sent by a wireless working station STA, where the probe request message carries a Media Access Control MAC (Media Access Control, Media Access Control) address of the STA.
[0110] Specifically, the wireless access point AP broadcasts the information of the AP to the outside, including the name of the AP, authentication mode, encryption mode, working mode and so on. The wireless working station STA selects an appropriate AP to access according to the information broadcast by the AP. In the process of accessing the wireless local area network, the STA sends a probe request message to the AP, where the probe request message carries the STA's MAC address.
[0111] 102. Determine whether to store association information of the STA according t...
Embodiment 2
[0164] The embodiment of the present invention also provides a method for accessing a wireless local area network, specifically as image 3 In the illustrated embodiment, when the association information of the STA and the IP address of the STA are not stored, the interaction between the AP and the STA is elaborated, specifically as follows Figure 4 shown, including:
[0165] 401. An AP broadcasts hotspot information, so that a STA discovers the AP.
[0166] Specifically, the wireless access point AP broadcasts the information of the AP to the outside, including the name of the AP, authentication mode, encryption mode, working mode and so on. The wireless working station STA selects an appropriate AP to access according to the information broadcast by the AP.
[0167] 402. The STA sends a detection request message to the AP.
[0168] In the process of accessing the wireless local area network, the STA sends a probe request message to the AP, where the probe request message...
Embodiment 3
[0252] An embodiment of the present invention provides a device 600 for accessing a wireless local area network, specifically as Image 6 As shown, the apparatus 600 includes a receiving unit 601 , a determining unit 602 , a sending unit 603 , a processing unit 604 , and an allocating unit 605 .
[0253] The receiving unit 601 is configured to receive a probe request message sent by a wireless working station STA, where the probe request message carries a medium access control MAC address of the STA.
[0254] The determining unit 602 is configured to determine whether to store the association information of the STA according to the MAC address, where the association information includes the MAC address and session association ID of the STA.
[0255] The sending unit 603 is configured to send an association response message to the STA if the determining unit 602 determines that the association information of the STA has been stored, where the association response message carrie...
