WLAN authentication method, WLAN authentication system and AP equipment

Abstract

The invention relates to an WLAN authentication method, a WLAN authentication system and AP equipment. The WLAN authentication method comprises the steps of transmitting an identity authentication request to a WLAN platform after a networking request from a client is received; then receiving a redirected portal address from the WLAN platform, and transmitting a logging-on interface of the portal address to the client; after receiving a logging-on request which is transmitted from the client, forwarding the logging-on request to the WLAN platform, and receiving a first redirected message of a response logging-on request of the WLAN platform and forwarding the first redirected message to the client; after receiving a networking request which is retransmitted from the client according to the first redirected message, transmitting a client authorization state searching request to the WLAN platform; and after receiving a first response which is authorized by the client, authorizing the networking right of the client, and transmitting a second redirected message for responding the networking request to the client. According to the WLAN authentication method, the WLAN authentication system and the AP equipment, the request is transmitted to the WLAN platform through the AP equipment in networking operation and network disconnecting operation of the client, thereby simplifying a data processing flow, reducing a data transmission rate and saving bandwidth.

Description

technical field [0001] The invention relates to the technical field of communication, in particular to a wlan authentication method and system, and AP equipment. Background technique [0002] Wlan authentication is essentially an authentication process for captive portal websites that use wireless access technology to access the Internet. It's just that the expression form of the authentication process is transferred from the traditional PC wired network access to the wireless network access of the mobile terminal equipment. The current process of the existing wlan authentication access system follows the "China Mobile WLAN Device Interface Specification", such as figure 1 As shown, the devices involved include PORTAL server, AP device, AC device, RADIUS server, AAA accounting server, etc. For a user to complete the user online authentication action, data exchange between the above-mentioned devices and the server is required, and the format of the message protocol used is...

Problems solved by technology

The above-mentioned devices or servers may be located between different subnets, which will lead to the situation of crossing network segments in the horizontal direction and crossing network layers in the vertical direction

In terms of deployment and use, it is very easy to affect the interconnection and intercommunication of the above-mentioned devices, causing confusion in management; secondly, the various protocols used between devices and servers in the network generate a lot of heterogeneous data, which is not convenient for unified processing and increases data adaptability. The processing intensity of the distribution layer, and the data flow between the equipment and the server in the network presents an irregular flow with the increase in the scale of equipment and servers; in addition, there are many equipment and servers in the network, resulting in input costs higher, more expensive
