Radio-communication terminal device that prevents communication through an unauthenticated antenna
First Claim
1. A radio-communication terminal device comprising:
- an antenna unit that includes;
an antenna element for transmitting and receiving radio signals; and
an authenticator for indicating an authentication of the antenna unit; and
a transceiver unit that includes;
a transmission circuit that transmits radio signals to the antenna unit;
a reception circuit that receives radio signals from the antenna unit;
an authentication detector that determines whether the authenticator indicates the authentication of the antenna unit; and
a communication controller for preventing communication through the antenna unit when the authentication detector does not indicate the authentication.

Abstract
A radio-communication terminal device having an antenna unit incorporating an antenna element and an authenticator for authenticating the connected antenna element, and a transceiver unit that includes a transmission circuit, a reception circuit, an authentication detector and a communication controller. The antenna unit further includes a first antenna connector and a first connector. The transceiver unit includes a second connector that connects to the first connector when the first antenna connector connects to the second antenna connector. The authentication detector detects the authentication of the authenticator when the first connector is connected to the second connector. The communication controller prevents the transmission circuit from transmitting signals when the authenticator cannot authenticate the connection to the antenna unit.

31. A method for authenticating a connection between an antenna unit and a transceiver unit in a radio-communication terminal device, the method comprising:
-
connecting the antenna to the transceiver unit; switching the radio-communication terminal device to an authentication detection mode; detecting a signal from the authenticator; comparing the signal from the authenticator to a signal in the authentication detector within the transceiver unit; sending a signal to a communication controller indicating that an authentication is detected; and preventing the transmission circuit from transmitting signals to the antenna unit when the communication controller determines that the authentication detector does indicate the authentication. - View Dependent Claims (32, 33, 34, 35)

36. A method for detecting a proper connection between an antenna unit and a transceiver unit in a radio-communication terminal, the method comprising:
-
connecting the antenna unit to the transceiver unit; detecting information from an authenticator in the antenna unit; comparing the information from the authenticator with information stored in the transceiver unit in an authentication detector; sending a signal from the authentication detector to a communication controller indicating that an authentication is detected; preventing the transmission circuit from transmitting signals to the antenna unit when the communication controller determines that the authentication detector does not indicate the authentication.
