User access control method and system for wireless local area network

Abstract

The invention provides a user access control method and a user access control system for a wireless local area network, and relates to a wireless local area network technology. The user access control method for the wireless local area network comprises that: an authentication portal server receives an access point (AP) authentication request initiated by a user terminal; the authentication portal server transmits the related authentication information of the user terminal to an authentication, authorization and accounting (AAA) server by a multi-service edge (MSE) according to the AP authentication request initiated by the user terminal; the AAA server authenticates the user terminal, and transmits an authentication result and preset user level information to an access point (AP) by the MSE; after the user terminal passes the authentication, the AP detects current traffic; and the AP judges whether to permit the accessing of the user terminal according to the current traffic, the user level information and a preset traffic threshold value. By the method and the system, the accurate and differential user access control of the wireless local area network (WLAN) can be effectively realized, the resource utilization rate of the WLAN can be increased and user perception can be improved.

Description

technical field [0001] The invention relates to wireless local area network technology, in particular to a wireless local area network user access control method and system. Background technique [0002] A Wireless Local Area Network (WLAN, Wireless Local Area Network) is an important means to realize broadband wireless access for users. Usually a WLAN network includes a wireless client, an access point (AP, Access Point) and a wireless controller (AC: Access Controller), wherein the wireless client is a personal computer (PC: Person Computer) with a wireless network card or a portable For terminals such as notebook computers, the AP is used to provide the bridging function from the wireless client to the LAN, and perform wireless-to-wired and wired-to-wireless frame conversion between the wireless client and the LAN. [0003] Now in the implementation of WLAN project, the number of users connected at the same time on the AP is limited by statically setting the number of ac...

Problems solved by technology

The above method has the following deficiencies: first, the access control is only based on the number of users, and the control is not accurate enough, because a large number of users does not necessarily mean a large traffic; second, the priority level of users is not considered, especially for high-priority users Does not reflect a differentiated access control strategy
