Abstract

A communication inhibiting apparatus is provided with: disturbing wave generating means for generating a disturbing wave signal which disturbs communications to and from a portable telephone or similar communication terminal equipment; and disturbing wave emitting means for emitting the signal generated by said disturbing wave generating means, as said disturbing wave, to said communication terminal equipment.

Claims

1. A communication inhibiting apparatus, comprising:

disturbing wave generating means for generating a disturbing wave signal which disturbs communications to and from a portable telephone or similar communication terminal equipment;

disturbing wave emitting means for emitting the disturbing wave signal generated by said disturbing wave generating means as a disturbing wave to said communication terminal equipment;

transmitted wave detecting means for detecting a transmitted wave from the communication terminal equipment; and

control means for controlling the disturbing wave generating means to generate the disturbing wave signal upon detecting said transmitted wave by said transmitted wave detecting means, wherein

said control means controls the disturbing wave generating means to generate the disturbing wave signal a predetermined time after the detection of the transmitted wave by the transmitted wave detecting means in order to give said communication terminal equipment a predetermined time for recording a history of incoming calls and/or for receiving a call which does not need immediate reception by a receiver, such as a text message or a voice mail message.

2. A communication inhibiting apparatus, comprising:

disturbing wave generating means for generating a disturbing wave signal which disturbs communications to and from a portable telephone or similar communication terminal equipment;

disturbing wave emitting means for emitting the disturbing wave signal generated by said disturbing wave generating means as a disturbing wave to said communication terminal equipment;

transmitted wave detecting means for detecting a transmitted wave from the communication terminal equipment;

control means for controlling the disturbing wave generating means to generate the disturbing wave signal upon detecting said transmitted wave by said transmitted wave detecting means; and

storage means for storing frequency channel information on various mobile communication systems, wherein

upon detecting the transmitted wave from the communication terminal equipment by the transmitted wave detecting means, the control means estimates, based on the frequency channel information stored in said storage means, the receiving frequency of said communication terminal equipment which is used corresponding to the frequency of said transmitted wave, and controls the frequency of the disturbing wave signal which is generated by the disturbing wave generating means.

3. A communication inhibiting apparatus, comprising:

disturbing wave generating means for generating a disturbing wave signal which disturbs communications to and from a portable telephone or similar communication terminal equipment;

disturbing wave emitting means for emitting the disturbing wave signal generated by said disturbing wave generating means as a disturbing wave to said communication terminal equipment;

transmitted wave detecting means for detecting a transmitted wave from the communication terminal equipment;

control means for controlling the disturbing wave generating means to generate the disturbing wave signal upon detecting said transmitted wave by said transmitted wave detecting means; and

storage means for storing frequency band information and TDMA slot information on the time axis of TDMA mobile communication systems, wherein

upon detecting the transmitted wave from the communication terminal equipment by the transmitted wave detecting means, the control means estimates, based on the frequency band information and the TDMA slot information stored in said storage means, the receiving frequency of the communication terminal equipment which is used corresponding to the frequency of said transmitted wave, and controls the frequency and generation timing of the disturbing wave signal which is generated by the disturbing wave generating means.
