Network access control method, device and system

Abstract

The embodiment of the invention provides a network access control method, device and system. When a portal authentication passing message, sent by a portal server, of user equipment is received, the state of the user equipment is recorded to be online; when the offline condition of the user equipment is monitored, the state of the user equipment is changed into the aging state; whether the message sent by the user equipment is received or not within the set aging time is judged, if the message sent by the user equipment is received, the state of the user equipment is changed to be online from aging, and if the message sent by the user equipment is not received, the state of the user equipment is changed to be offline from aging; according to the state of the user equipment, the user equipment is controlled to have access to the network, and therefore the access authentication process of the user equipment is optimized when the user equipment leaves the network for a short time is optimized, and the phenomenon that a user frequently executes login authentication operation is avoided.

Description

technical field [0001] The present invention relates to communication technology, in particular to a network access control method, device and system. Background technique [0002] With the continuous development of communication network technology, various methods for user equipment to access the network emerge as the times require. Among them, user equipment, such as mobile phones, computers, or PDAs, can access the network through an access point (AP for short) under the control of an access controller (AC for short). Previously, portal authentication was required. [0003] In the prior art, when the AC receives a web page access request initiated by a user equipment but has not performed portal authentication, it will forcefully redirect the web page access request to a portal server, also called a portal server. The portal server forwards the authentication portal webpage to the user equipment, and the user submits the user name and password through the portal webpage...

Problems solved by technology

[0004] However, when the user equipment adopts power-saving mode, or leaves the network signal coverage area for a short time, or the user closes the authentication portal web page, etc., the portal server will generate a login and logout instruction, and notify the AC to disconnect the user equipment from the network.

When the user device transmits data streams between the network side again, the portal authentication process needs to be re-executed, which increases the complexity of the user device's access to the network, reduces access efficiency, and affects user experience.
