Network access control method and system

Abstract

The invention relates to a network communication technology. Aiming at overcoming a defect that access speed is lower in the prior art, the invention discloses a network access control method and system, and increases the access speed and quantity of terminal devices. The network access control method comprises the steps that A, when the terminal devices access for the first time, a first-time authentication request is sent to an authentication server from a network server; B, after the first time authentication is passed, the authentication server stores identity information of the terminal devices and the identity information is bound with user information; C, when the terminal devices access again, an authentication request is sent to the authentication server directly; and D, the authentication server checks the identity information of the terminal devices, authentication is passed when the identity information is matched with the information stored in the authentication server, and the terminal devices are allowed to have an access to a network for a visit. The network access control system comprises the terminal devices, an access device, the network server and the authentication server. The method and the system simplify access control procedures and increase the access speed of a user to the network.

Description

technical field [0001] The invention relates to network communication technology, in particular to a method and system for network terminal device access control. Background technique [0002] There are generally two traditional network access control methods, one is the control method based on the 802.1X protocol (client / server-based access control and authentication protocol), and the other is the MAC (Media Access Control Protocol) address binding control method. 802.1X technology network terminal equipment needs to install 802.1X client program, the management and maintenance workload is very heavy, and many terminal equipment do not support the installation of 802.1X, so many terminal equipment need to rely on the assistance of MAC address binding method, and MAC address binding A certain method needs to collect a large number of MAC addresses, and manually complete the binding work on the access device. [0003] In order to solve this kind of problem, someone propose...

[0004] However, in this method, when the user accesses the network for the second time, he needs to query the Portal server and re-initiate the Portal authentication process, resulting in a slow user access speed, and requires the Portal server to have relatively high processing performance, which limits the access of terminal devices. quantity
