TERMINAL APPARATUS CARRYING OUT COMMUNICATIONS AFTER AUTHENTICATION, A COMMUNICATION SYSTEM, AND A COMMUNICATION METHOD

摘要

An acquiring unit acquires the positional information. A first request unit requests an authentication station to perform authentication by using the positional information acquired by the acquiring unit. When the authentication station grants authentication for a request from the first request unit, a communication processing unit carries out communications using a first radio communication system. When authentication required for carrying out the communications using the first radio communication system is not performed in the communication processing unit, a second request unit requests another terminal apparatus to perform authentication by using a second radio communication system, whose transmission distance is shorter than the first radio communication system.

主权项

1. A terminal apparatus comprising:
an acquiring unit that acquires positional information; a first request unit that requests an authentication station to perform authentication by using the positional information acquired by the acquiring unit; a communication unit that carries out communication using a first radio communication system, when a request from the first request unit has been authenticated by the authentication station; and a second request unit that requests another terminal apparatus to perform authentication by using a second radio communication system, whose transmission distance is shorter than the first radio communication system, when authentication required for carrying out the communication using the first radio communication system is not performed in the communication unit.
