Abstract

The invention relates to a method for realizing a convergence WAPI network architecture in separated MAC mode, which comprises the following steps: 1) constructing the separated MAC mode for realizingWPI through a wireless terminal point, and separating MAC function and WAPI function of a wireless access point onto the wireless terminal point and an access controller; and 2) realizing fusion of WAPI and a convergence WLAN network system architecture in separated MAC mode for realizing WPI by the wireless terminal point; 2.1) an association connecting process of a site and the wireless terminal point and the access controller; 2.2) a notification process of execution of WAI protocol between the access controller and the wireless terminal point; 2.3) an execution process of WAI protocol between the site and the access controller; 2.4) a notification process of the ending of execution of the WAI protocol between the access controller and the wireless terminal point; and 2.5) a secret communication process between the wireless terminal point and the site by WPI. The method not only can meet the requirement of large-scale deployment of WLAN, but also can ensure the safety of WLAN underthe convergence system architecture.

Description

technical field [0001] The invention relates to a method for realizing convergent WAPI network architecture in a separate MAC mode. Background technique [0002] In the WLAN (Wireless Local Area Networks) of the autonomous architecture, the wireless access point AP (Access Point) is fully deployed and terminated with the GB15629.11 function, and is managed independently as a separate entity on the network. At present, WLANs designed based on WLAN Authentication and Privacy Infrastructure (WLAN Authentication and Privacy Infrastructure) adopt autonomous architecture, but with the expansion of WLAN deployment scale, the network working mode of this autonomous architecture has inherent defects Has gradually become an obstacle restricting the development of wireless technology. [0003] First, in a WLAN with an autonomous architecture, APs, as Internet Protocol (IP) addressable devices, need to be independently managed, including monitoring, configuration, and control. During ...

AI Technical Summary

Problems solved by technology

In a large-scale WLAN, the workload of updating the dynamic configuration of APs on the entire network in time is very heavy, and even impossible

[0005] Third, in WLAN, the wireless transmission medium is a shared resource. In order to improve the performance of the network, each AP must be monitored in real time and the configuration of these APs must be dynamically updated according to the current usage of the shared medium. Manual configuration and wireless transmission Medium-related AP parameters will consume a lot of manpower and material resources

[0006] Fourth, in WLAN with autonomous architecture, it is also difficult to securely access the network and prevent illegal APs from joining

It can be seen that the working mode of the autonomous architecture WLAN can no longer meet the deployment requirements of large-scale networks, and it is urgent to design a WAPI-based convergent WLAN network architecture, that is, the WAPI thin AP architecture
