Web authentication method, network device and web authentication system

Abstract

The invention provides a Web authentication method, network equipment and a Web authentication system. The Web authentication method comprises the following steps: after a user terminal passes Web authentication, access equipment records authentication information of the user terminal; and if the access equipment knows that an authentication keep-alive page of the user terminal does not send keep-alive information in a preset keep-alive information sending period by detection and knows that the user terminal is accessed to a wireless network covered by the access equipment or detects the flow of the user terminal, the access equipment sends the keep-alive information to an authentication server according to the recorded authentication information of the user terminal, so that the authentication server keeps network connection of the user terminal. By adopting the Web authentication method, the network equipment and the Web authentication system, which are provided by the invention, the user terminal can still be ensured to normally use the network when the user terminal and the Web authentication are not compatible.

Description

technical field [0001] The invention relates to the technical field of communication, in particular to a Web authentication method, network equipment and a Web authentication system. Background technique [0002] With the popularization and development of wireless local area network (Wireless Local Area Network, WLAN), the web authentication mechanism has been widely used. [0003] figure 1 It is a flowchart of a prior art Web authentication method. Such as figure 1 As shown, it can be known that in the existing Web authentication technology, the user terminal (STA) accesses the network through the wireless access point (Access Point, AP), and at the same time sends the http authentication server (AS) through the access device (AC). Request; the AS pushes the web authentication page to the STA, and the STA fills in the necessary information and submits it to the AS, so that the AS can authenticate the STA. The STA can use the network only after passing the authentication...

AI Technical Summary

Problems solved by technology

If the web authentication page is actively closed, an offline notification will be sent to the authentication server; if the authentication page is closed abnormally, the web authentication will time out, resulting in the forced offline of the user terminal

[0004] In practical applications, because some mobile terminals are not compatible with web authentication page jumping, after the user terminal browses other web pages, the web authentication page will be forcibly closed, so the user terminal will be forced to go offline and cannot continue to use the network
