COMMUNICATION SYSTEM AND COMMUNICATION TERMINAL APPARATUS

摘要

In a case when a mode relating to a function limitation of the communication terminal apparatus or a notification mode relating to that function limitation is set in response to the communication state between the communication terminal apparatus 10 and the wireless key apparatus 50, the communication terminal apparatus and the wireless key apparatus include judgment means for judging or presuming the wireless communication state or the wireless communication distance in the communication circuit, the communication terminal apparatus and the wireless key apparatus are wireless-connected, and in a case when a communication state for carrying out a wireless communication intermittently is set in each communication circuit and there is judgment or presumption of a predetermined state in the judgment means in a state in which the wireless connection is maintained, the mode setting relating to the function limitation or the notification mode setting relating to the function limitation is to be changed. In this way, in a case when a process which carries out a security control of a communication terminal apparatus such as a mobile telephone terminal is carried out in response to a wireless communication state with another communication apparatus, it is possible to carry out a mode setting of the security control or the like by a low power consumption favorably.
