The present invention is to provide a network connection control method capable of minimizing a cost when service is provided via Internet. User authentication information sent together with an Internet connection request from a user terminal 5 relevant to a NAS (Network Access Server) 6 managed by an access provider, is transferred to an authentication server 7 managed by the provider. When the user authentication information meets a predetermined condition, the user authentication information is transferred to an authentication server 10 managed by a service provider which is different from the provider. Then, user authentication is executed, referring to a database 15 associated with the authentication server 10, and the user authentication result is returned to the authentication server 7. The authentication server 7 notifies the authentication result to the NAS 6 from the authentication server 10. The NAS 6 controls whether the user terminal 5 enabled or disables connection to Internet 1 based on the result of the notified user authentication.
