Abstract
It was constituted such that in a case when a function of the communication terminal apparatusis limited in response to a wireless communication state between the communication terminal apparatusand the wireless key apparatus, it is controlled in the wireless key apparatussuch that a communication connection with the communication terminal apparatusis to be carried out; the function of the terminal apparatusis to limited in the communication terminal apparatusin a case when a predetermined communication state cannot be maintained with respect to the wireless key apparatusand at the same time; and in a case when it is detected that the terminal apparatusexists in a predetermined region such as in the vicinity of the apparatusor the like, the function of the terminal apparatusis not to be limited regardless of the communication state with respect to the wireless key apparatus. In this manner, low power consumption can be attempted in a case when a security process of a communication terminal apparatus such as a mobile telephone terminal is carried out by a wireless communication.
