The present invention relates to a cellular telephone device and a transmitter for transmitting to cellular telephones and more particularly to cellular telephone technology and a transmitter for transmitting to cellular telephones for switching the cellular telephone mode to sleep mode or silent mode or answering mode in a specified location, time, circumstances or environment, and automatically turning off the transmission.
Along with the widespread use of cellular telephones, the problems of bad manners when using cellular telephones and adverse effects from radio waves have appeared. For example, to prevent annoying other people by using cellular telephones, public traffic systems such as for buses and trains make announcements within the bus or train compartment requesting that passengers refrain from using cellular telephones. However, this request is not always obeyed. Hospitals and medical clinics post signs and make announcements requesting that cellular telephones be turned off, but these cellular telephones are often willfully or by mistake left on. To prevent annoying or inconveniencing others, places such as theaters, movie theaters and concert halls post signs and make announcements to inform people that cellular telephones should be turned off while viewing a play, a movie or a music performance, but this warning is not always complied with. People also continue to use cellular telephones while driving in spite of the fact that many accidents occur due to use of cellular telephones while driving automobiles.
Technology is disclosed in Japanese Unexamined Patent Publication No. 224064/2001 for a cellular telephone information terminal (hereafter cellular phone terminal) for storing reference point position information ahead of time in a reference point memory section, measuring the position of the cellular phone terminal by GPS (Global Positioning System) processing, calculating the distance from the cellular phone terminal position to the reference point in a distance data processor and comparing it with a specified threshold value, and when within the threshold, allowing calls to be made from the cellular telephone by control from a call controller, and when in excess of the threshold forbidding or prohibiting calls from being made.
FIG. 1 is an overall concept view showing the first embodiment of the cellular telephone system of the present invention.
FIG. 2 is a block diagram showing an embodiment of the overall operation of the cellular telephone of the present invention.
FIG. 3 is a flowchart showing an embodiment of the processing operation of the cellular telephone device of the present invention.
The embodiments of the present invention are described hereafter while referring to the accompanying drawings.
FIG. 1 is an overall concept view showing the first embodiment of the cellular telephone system of the present invention. A cellular telephone 1 in the figure is present within a designated area (or designated location) 2, and capable of communicating with a first base station 3. When radio waves are transmitted from the cellular telephone 1, these are received by a first base station 3, sent to a cellular telephone system server 4, and transmitted to the cellular telephone or fixed telephone of another party by way of a general public pay (telephone) net 5.
FIG. 2 is a block diagram showing an embodiment of the overall operation of the cellular telephone of the present invention. In the figure, the CDMA (Code Division Multiple Access) signal and GPS (Global Positioning System) signal received from the antenna 21 are input via the transmit/receive selector switch 22 to the CDMA Amplifier 23 or the GPS amplifier 24 and communications processor 25 and voice audio is output from a speaker 26. In the case of electric mail (hereinafter mail), a display is shown on an LCD 27. Voice audio from the microphone 28 is output from the antenna 21 after passing the communication processor 25, the transmit CDMA Amplifier 29, and the switch 22. The keys 30 are provided for entering the telephone number or entering the mail characters in the cellular telephone. A memory 31 is also installed for recording different functions and telephone numbers. A camera 32 is also sometimes installed for sending images.
