摘要

PURPOSE: A network service access method, a system and a program, a storage medium for storing the program, an access point structure and a wireless user terminal are provided to guarantee authentication of a service vender to be used by a wireless user terminal when the wireless user terminal establishes an association with an access point, thereby removing an unavailable association process while saving wireless resources. CONSTITUTION: A wireless user terminal(10) is connected to service venders(40A,40B,40C) while being installed with a wireless LAN interface. An access point(20) supplies a connection to the service venders(40A,40B,40C) by using a wireless LAN by performing an association with the wireless user terminal(10). A V-LAN(Virtual LAN) switch(30) connects the wireless user terminal(10) connected to the access point(20) with a specific one of the service venders(40A,40B,40C). The service venders(40A,40B,40C) supply network services to the connected wireless user terminal(10).
