Problems solved by technology

[0003] However, when the STA is disconnected from the network for some reason, such as the user equipment is turned off, or the user is disconnected from the network, or the STA roams between Wlan terminals and needs to quickly switch to the network, if the connection of the traditional Wlan network is still used In the process of entering, the process of authentication, association and key negotiation must be re-initiated to obtain the IP address again, which will make the efficiency of users accessing the wireless LAN lower and greatly reduce the user experience.

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...

Abstract

The invention provides a method and a device used for accessing a wireless local area network. A user can quickly access the wireless local area network. The efficiency of network accessing is improved. The user experience is enhanced. The method comprises the steps that a wireless access point AP receives a detection request message sent by a wireless work site STA; according to a medium access control MAC address carried by the detection request message, whether the association information of the STA is stored is determined; if the fact that the association information of the STA is stored is determined, an association response message is sent to the STA; according to a session association ID carried by the association response message, secret key negotiation with the STA is carried out; and an IP address which accesses the wireless local area network this time is distributed to the STA, so that the STA accesses a network source according to the IP address. The method and the device, which are provided by the invention, are applicable to the field of communication.

Description

technical field [0001] The invention relates to the communication field, in particular to a method and device for accessing a wireless local area network. Background technique [0002] With the popularization of mobile wireless products, users' requirements for accessing wireless networks continue to increase. The access process of the traditional Wlan (Wireless Local Area Network) network includes: after the administrator configures the password, inform the user who is allowed to access, the user uses the same password, manually input, STA (Wireless Station, wireless work station) and AP (Access Point, wireless access point) After authentication, association and key negotiation are passed, access to the Wlan network. [0003] However, when the STA is disconnected from the network for some reason, such as the user equipment is turned off, or the user is disconnected from the network, or the STA roams between Wlan terminals and needs to quickly switch to the network, if the ...
