Abstract

There are provided a cellular telephone device and transmitter for setting a cellular telephone to answering mode and a telephone section to sleep status when communication forbidding information is received, and restoring telephone section operation when there is no communication forbidding information and canceling silent mode and answering mode; and automatically setting silent mode and answering mode when a communication forbidding signal is received, and maintaining the telephone section operation status when there is no communication forbidding information, and canceling silent mode and answering mode.

Claims

1. Cellular telephone device comprising:

a radio-frequency part including a telephone section for sending and receiving radio frequency communication signals; and

,

a processor for controlling said radio frequency part so as to maintain said telephone section in sleep status when communication forbidding information is received, so as to restore said telephone section in operation status when said communication forbidding information is no longer received, and so as to send an answering mode cancel request signal.

4. Cellular telephone device according to claim 1, wherein said communication forbidding information is specified communication forbidding information.

7. Cellular telephone device according to claim 1, wherein communication prohibit mode is cancelled and an emergency telephone mode is set to enable making calls to another party.

2. Cellular telephone device comprising:

a radio-frequency part for receiving communication forbidden area proximity information; and

,

a warning device for giving a warning with characters, sound, or vibration when communication forbidden area proximity information is received.

3. Cellular telephone device comprising:

a radio-frequency part including a telephone section for sending and receiving radio frequency communication signals; and

,

a processor for periodically measuring the field intensity of radio waves from a first base station and the field intensity of radio waves from a second base station, detecting changes in said field strength over a unit of time, and sending an answering mode registration request signal when determined to be moving, maintaining said telephone section in sleep status, and when movement can no longer be detected, restoring said telephone section to operation and sending an answering mode request cancel signal.

5. Cellular telephone device comprising:

a radio-frequency part including a telephone section for sending and receiving radio frequency communication signals; and

,

a processor capable of receiving communication forbidden time period information within designated area, sent from a communications device installed in said designated area, and said processor controlling said telephone section so as to send an answering mode registration request signal when said communication forbidden time period is started, and maintaining said telephone section in sleep status during said communication forbidden time period, and said process restoring said telephone section in operation status and to sending an answering mode cancel request signal when said communication forbidden time period has elapsed.

6. Cellular telephone device comprising:

a radio-frequency part including a telephone section for sending and receiving radio frequency communication signals;

a smell sensor capable of detecting specific odors, wherein when said smell sensor detects said specific smell, then that area is determined to be a communication forbidden area; and

,

a processor for controlling said radio frequency part so as to send an answering mode registration request signal, to maintain said telephone section in sleep status, and to send an answering mode cancel request signal when said smell can no longer be detected.

8. Cellular telephone device according to claim 14, wherein a communication prohibit cancel button is installed, and said emergency telephone mode is set by pressing said communication prohibit cancel button.

9. Cellular telephone device comprising:

a camera; and

,

an emergency mode switcher, ‘

wherein when set to emergency mode by said emergency mode switcher means, pictures are automatically taken by said camera and sent to a pre-specified address.

10. Cellular telephone device comprising:

a voice signal output part;

a speaker to change the signal from said voice signal output means to audio; and

,

an audio quality degradation part,

wherein when receiving communication or communication forbidding information, said device connects said audio quality degradation part between said voice signal output part and said speaker.

11. Cellular telephone device comprising:

a radio-frequency part including a telephone section for sending and receiving radio frequency communication signals;

to and,

a processor for measuring the field intensity of radio waves from a first base station and the field intensity of radio waves from a second base station at periodic intervals, detecting the changes in field strength over units of time, maintaining said telephone section in operating status when determined to be moving, setting silent mode and answering mode, and automatically canceling said silent mode and said answering mode when communication forbidding information is no longer received.

12. Cellular telephone device comprising:

a radio-frequency part including a telephone section for sending and receiving radio frequency communication signals;

a smell sensor capable of detecting specific odors in said cellular telephone device, wherein when said smell sensor detects said specific smell, then that area is determined to be said communication forbidden area; and

,

a processor for controlling said radio frequency part so as to maintain said telephone section in operating status, and to set said silent mode and answering mode, and automatically canceling said silent mode and said answering mode when said smell can no longer be detected.

13. Cellular telephone device comprising:

a radio-frequency part including a telephone section for sending and receiving radio frequency communication signals; and

,

a processor for controlling said radio frequency part so as to maintain said telephone section in operating status when communication forbidding information is received, and to set silent mode and answering mode, to cancel communication forbidden status, and to set an emergency telephone mode for calling another party.
