    • It is constituted such that a function limitation is to be applied to a communication terminal apparatus of a mobile telephone terminal or the like at a place far from wireless key by a constant distance and it is also constituted such that after the function limitation is applied once, it is made impossible for the function limitation to be released until the communication terminal. The transmission power is controlled in response to the state by utilizing a phenomenon that the communication possible distance between the apparatuses changes according to the amount of the transmission power wireless-communicated. Specifically, with respect to the transmission power on the occasion when a connection operation is carried out between the communication terminal apparatus and the wireless key, it is constituted for the transmission power from at least one of apparatuses such that the transmission power when releasing the function limitation is made smaller than the transmission power when applying the function limitation. Further, after the function limitation is released, the transmission power is again increased to the original transmission power when applying the function limitation.
    • 其功能限制构成为将远离无线键的位置的移动电话终端等的通信终端装置以一定的距离应用,并且还构成为在功能限制被应用一次之后 ,直到通信终端才能释放功能限制。 通过利用设备之间的通信可能距离根据无线通信的发送功率的量而变化的现象,响应于状态来控制发送功率。 具体而言,关于在通信终端装置与无线键之间进行连接动作的情况下的发送功率,构成为来自至少一个装置的发送功率,使得在释放功能时的发送功率 当应用功能限制时,限制比发送功率小。 此外,在功能限制解除之后,当应用功能限制时,发送功率再次增加到原始发送功率。

    • In a case when a wireless communication is carried out between a communication terminal apparatus and a wireless key apparatus in which one of the two apparatuses which carry out the communication becomes a master and the other one becomes a slave, the slave detects a signal from the master and the wireless communication is carried out by a wireless communication system executing the wireless connection between the two apparatuses, it is constituted such that each of the communication terminal apparatus and the wireless key apparatus includes communication means for carrying out the wireless communication, and control means; and in a case when the wireless communication state between the communication terminal apparatus and the wireless key apparatus is a non-connection state, the side which becomes the master is to transmit a signal asking for a “response from the slave” intermittently by changing the period into a plurality of steps in response to the non-connection time period and the side which becomes the slave is to carry out a reception for searching a signal from the master intermittently by changing the period into a plurality of steps in response to the non-connection time period. It may be expected by this constitution that a communication terminal apparatus such as a mobile telephone terminal can be connected wirelessly with another terminal apparatus rapidly by low power consumption.

    • 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.
