Abstract

The mobile communication terminal device has a security communication function, and includes a detection unit for detecting the security level of the destination of connection, and an announcing unit for announcing the detected security level. The user is able to confirm whether security is ensured at the connectee.

Claims

1. A mobile communication terminal device having a security communication function, comprising:

a detection unit for detecting the security level of the destination of connection; and

an announcing unit for announcing said detected security level.

2. A mobile communication terminal device according to claim 1, further comprising a judgment unit for judging whether said detected security level satisfies a prescribed condition, and wherein said announcing unit announces the results of said judgment.

3. A mobile communication terminal device according to claim 2, further comprising a security level setting unit for setting at least one of a security level permitting communication and a security level not permitting communication.

4. A mobile communication terminal device according to claim 3, further comprising a control unit for discontinuing communication when said detected security level has not reached said security level permitting communication or falls below said security level not permitting communication.

5. A mobile communication terminal device according to claim 3, wherein said announcing unit urges the selection of the continuance or discontinuance of communication when said detected security level has not reached said security level permitting communication or falls below said security level not permitting communication.

6. A mobile communication terminal device according to claim 1, further comprising a notification unit for notifying the caller of the discontinuance of communication when communication is discontinued based on the security level detected at the time of call reception.

7. A server device for communicating with a mobile communication terminal device via a communication network, comprising:

a server side detection unit for detecting the security level; and

a server side security level setting unit for setting at least one of a security level permitting communication and a security level not permitting communication.

8. A server device according to claim 7, further comprising a server side control unit for discontinuing communication when said detected security level has not reached said security level permitting communication or falls below said security level not permitting communication.

9. A server device according to claim 7, further comprising:

an inquiry unit for making an inquiry to said mobile communication terminal device to select either the continuance or discontinuance of communication when said detected security level has not reached said security level permitting communication or falls below said security level not permitting communication; and

a server side control unit for continuing or discontinuing communication in accordance with the response to said inquiry.
