Method for realizing integration of WAPI and CAPWAP by separation MAC mode

Abstract

The invention relates to a method for realizing the integration of a WAPI and a CAPWAP by a separation MAC mode. The method comprises the following steps: (1) constructing a separation MAC mode of realizing a WPI by an access controller: separating the MAC function and the WAPI function of a wireless access point on a wireless terminal point and the access controller; (2) under the separation MACmode of realizing the WPI by the access controller, realizing that a CAPWAP specification is bound to a WAPI protocol; (2.1) realizing a correlation connection process among a station, the wireless terminal point and the access controller; (2.2) realizing a notification process which is begun to be executed by a WAI protocol between the access controller and the wireless terminal point; (2.3) realizing an execution process of the WAI protocol between the station and the access controller; (2.4) realizing a notification process finishing the execution of the WAI protocol between the access controller and the wireless terminal point; and (2.5) realizing a process of carrying out secret communication by utilizing the WPI between the wireless terminal point and the station. The invention not only can meet the large-scale allocation requirement of a WLAN but also can ensure the safety of the WLAN under a convergence type system configuration.

Description

technical field [0001] The invention relates to a method for realizing integration of WAPI and CAPWAP in separate MAC mode. Background technique [0002] The wireless access point AP (Access Point) in the WLAN (Wireless Local Area Networks) of the autonomous architecture is fully deployed and terminated with GB15629.11 functions. As a separate entity on the network, independent management is required. 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 large...

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
