WIRELESS NETWORK ACCESS SYSTEM, TERMINAL, WIRELESS ACCESS POINT, REMOTE ACCESS SERVER, AND AUTHENTICATION SERVER

摘要

PROBLEM TO BE SOLVED: To provide a wireless network access system capable of designating an access destination network by each wireless LAN user. SOLUTION: When a terminal 1 of a wireless LAN user transmits information to authenticate the wireless LAN user to a wireless AP (Access Point) 2, the wireless AP 2 informs an authentication function 4 about this information. When the authentication function 4 authenticates the wireless LAN user, encrypted communication between the terminal 1 and the wireless AP 2 is established. Then the terminal 1 transmits authentication information for network access to a network for an ISP (Internet Service Provider) or an in- enterprise network or the like. A RAS (Remote Access Server) 3 decides a network terminator 6-1 or 6-2 for containing an access destination network from the network access authentication information and performs routing.
