Abstract

A wireless access point having a simple configuration provides a network service in accordance with a user level without placing a heavy burden on a user of a client station. The wireless access point controls connections among networks composed of a local network and a backbone network. The local network includes a wireless local network using a wireless communication medium. When establishing a communication association with a wireless station in the wireless local network, the wireless access point monitors a message in a user authentication sequence between the wireless station and an authentication server on a local network so as to acquire the authentication result and predetermined information associated with a login user, and determines a level of the login user. The wireless access point then sets up its own filtering function based on the determination.

Description

technical field [0001] The present invention relates to an access point for controlling connections between multiple networks and a method thereof. Background technique [0002] Recently, due to the widespread use of a wireless network system such as a wireless local area network (wireless LAN), a wireless network is used as a LAN, and there are wireless access point products with a filtering function for controlling connection with a backbone network. [0003] In addition, in order to ensure the security of network access, an extended authentication protocol (extended authentication protocol, EAP) is introduced to authenticate users. If the user's wireless station (station) is authenticated successfully, the wireless station is only authorized to connect to the network. [0004] In order to realize the seamless connection between the local network and the visited network on the IP (Internet Protocol, Internet Protocol) network, a method has been proposed, in which authenti...
