Problems solved by technology

That is to say, the current WLAN access control at home and abroad is based on whether it can be accessed as the only judgment, lacking various access control methods and access control when the network is congested, which is far from enough for practical applications

Embodiment Construction

[0049] The present invention adds user-level and device-level attributes to the certificate management library of the GB15629.11 standard system, and adds a network congestion state monitoring mechanism to the AP device, so that the background management control server can obtain the network and device working status in real time. When a new user terminal accesses, it sends the network status along with the authentication message, and performs access control according to the user and AP level settings and network congestion status.

[0050] figure 1 It shows the communication system of the present invention that can realize the congested call admission of the air interface of the wireless local area network, and the system includes a user terminal 1, a wireless access point (hereinafter referred to as AP) 2, an Ethernet switch 3, a public network 4, and a management server 5 and 3A server 6. Wherein the user terminal is a computer, mobile phone or PDA with a wireless network ...

Abstract

The invention discloses a control method and a system for realizing air interface congestion call admission of a wireless local area network. The control method comprises the following steps: leading a user terminal to send an access request to an AP; leading the AP to activate the identity authentication process by sending information about user identity, AP identity and AP congestion degree and level after receiving the access request; leading a management server to identify the user identity information, the AP identity information and the AP congestion degree and level, and then return identification information to the AP; leading the AP to carry out call admission control according to the identification result; and leading the AP and the user terminal which is allowed to access to carry out key agreement and data communication.

Description

technical field [0001] The invention relates to wireless local area network access, in particular to a method and system capable of realizing congestion call admission control on the air interface of the wireless local area network. Background technique [0002] Wireless Local Area Network (WLAN) is the product of the combination of computer network and wireless communication technology. It uses radio frequency (RF) technology to replace the old twisted-pair copper wires to form a local area network, and provides all the functions of a traditional wired LAN. The infrastructure required for the network does not need to be buried underground or hidden in the wall, and can also be moved as needed. or change. The wireless local area network can use the simple access framework to allow users to achieve the ideal state of "portable information and convenient access to the world". WLAN is the product of the combination of computer and wireless communication technology in the 1990...
