PROBLEM TO BE SOLVED: To solve problems of a communication device that is brought out in the public and used, and therefore secret information may be leaked through communication, while if its use is uniformly restrained by a position or time band in use, it cannot be used when urgent needs to make contact with the outside arise and the response to an emergency will be delayed.SOLUTION: In a communication device 2, disaster determination means 42 determines whether or not received disaster information indicates a particular disaster. A mode setting unit 44 normally sets the device to a restriction mode to restrict call origination by a user, switches to a release mode to cancel call origination restriction when it received disaster information indicating the particular disaster, and permits call origination temporarily. |
