Embodiment Construction

[0046] The present invention has used or implicitly used some basic concepts of wireless local area network, and they are respectively:

[0047] ●(Wireless) Access Point (Access Point, referred to as AP): refers to any entity that can provide distributed access services for wireless terminals through a wireless medium. A commonly used wireless router is a wireless AP with enhanced functions.

[0048]●Station (STA for short): that is, wireless terminals, specifically computers, portable notebooks, mobile handheld terminals, etc. that carry wireless network cards that support 802.11 series protocols and / or WAPI protocols.

[0049] ●Authentication Server (Authentication Server, referred to as AS): It is used to authenticate users and device certificates, and is an important part of WAI.

[0050] ●Service set identifier (SSID for short): SSID includes BSSID and ESSID, which are used to distinguish different networks. SSID is usually broadcast by AP, and SSID can be simply regarded...

Abstract

The invention discloses a method and device for processing wireless multiple-security-level services. The method includes the steps that multiple wireless access points are installed in different areas of an aircraft passenger cabin respectively; a wireless local area network is set up by physically connecting each AP to a network control device on an aircraft;the NC device divides wireless local area network data services into N types of services according to attributes of personnel on the aircraft, and the wireless local area network is configured to be N wireless virtual subnets corresponding to the N types of services, wherein N is an integer larger than 2; all wireless terminals of the aircraft passenger cabin are connected with the corresponding N wireless virtual subnets corresponding to the services of the wireless terminals respectively, wherein all the virtual subnets adopt different security types, for example, the subnet serving the high-security-level service adopts a WAPI certificate mode, the subnet serving the medium-security-level service adopts the security type of a WAP2 / WAP individual mode, and the subnet serving the low-security-level service adopts a public mode. Thus, the service requirements of different wireless terminals are met, and all the services are isolated according to the security level requirements.

Description

technical field [0001] The invention relates to the technical field of aircraft wireless Internet, in particular to a method and device for processing wireless multi-security level services suitable for wireless local area network communication in aircraft cabins. Background technique [0002] A wireless local area network (Wireless Local Area Network, hereinafter referred to as WLAN) technology is a very mature technology. A broad wireless local area network includes Bluetooth, IEEE 802.11 series, HiperLAN2 and other technical standards, and uses wireless channels to replace part or all of the transmission media in wired local area networks. Currently the most widely used WLAN technology is the IEEE 802.11 series of standards, which are the mainstream standards of the current WLAN. [0003] The IEEE 802.11 series standards have been formulated since 1997, and a relatively comprehensive standard system has been formed so far. The more famous standards include 802.11a, 802.1...
