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

Embodiment Construction

[0052] see figure 1 , according to a preferred embodiment of the present invention, its specific method is as follows:

[0053] 1) Build a local MAC mode: separate the MAC function and WAPI function of AP to WTP and AC;

[0054] 2) In the local MAC mode, realize the local MAC mode that binds the CAPWAP specification to WAPI;

[0055] 2.1) The association connection process between STA, WTP and AC;

[0056] 2.1.1) The STA passively listens to the WTP beacon frame to obtain WTP-related parameters, including WAPI information elements (WTP-supported WAI authentication and key management suites, cipher suites, etc.); or the STA actively sends an inquiry request frame to the WTP, After the WTP receives the inquiry request frame from the STA, it sends an inquiry response frame to the STA, and the STA receives the inquiry response frame from the WTP to obtain the relevant parameters of the WTP, including WAPI information elements (WTP-supported WAI authentication and key management ...

Abstract

The invention relates to a method for realizing the convergence of WAPI and CAPWAP in a local MAC mode. The method comprises the following steps: 1, building the local MAC mode: the MAC function and the WAPI function of wireless access points are separately set in a wireless terminal point and an access controller respectively; 2, realizing CAPWAP specifications binding WAPI protocol in the local MAC mode: 2.1, an relevancy connection process among sites, the wireless terminal point and the access controller; 2.2, an announcement process of starting the WAI protocol between the access controller and the wireless terminal point; 2.3, an implementation of the WAI protocol among the sites and the access controller; 2.4, an announcement process of ending the WAI protocol between the access controller and the wireless terminal point; and 2.5, a process of secret communication by using WPI among the wireless terminal point and the sites. The method of the invention not only meets the needs for the wide scale deploymentof WLAN, but also guarantees the security of WLAN in a convergence type system structure.

Description

technical field [0001] The invention relates to a method for realizing integration of WAPI and CAPWAP in local 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-sc...
