<p>Provided is a communication system which can connect only a communication terminal existing in a predetermined facility such as a restaurant to the Internet. A user position authentication server (16) analyzes distance information contained in the result of communication with a communication terminal (12) which has been received from an in-facility communication device (14) and judges whether the communication terminal (12) exists in a predetermined facility. If Yes, the authentication is successful. When the authentication is successful, a connection information providing unit (40) provides connection information required for connection with an access point (10) to the communication terminal (12) via the in-facility communication device (14). Thus, only the communication terminal (12) existing in the facility can be connected to the Internet via the access point (10).</p> |
