Benefits of technology

The present invention provides a cellular telephone device that can automatically switch between different modes based on information related to location, time, and circumstances. This is achieved by measuring the field intensity of radio waves from nearby base stations and detecting changes in field strength over time. The device can also be programmed to switch modes based on specific smells or other factors. The invention allows for improved convenience and efficiency for users of cellular telephones, especially in situations where communication is prohibited or restricted.

Problems solved by technology

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.
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.
In the conventional cellular telephone, as mentioned previously, actions such as turning off the cellular telephone or switching to answering mode are entrusted entirely to the cellular telephone user and so rules governing these actions are not always complied with.
Use of cellular telephones however, is not only is a great source of annoyance to other people but may also cause accidents so that a system for automatically turning off the telephone or setting it to answering mode is needed according to the specified location, time, circumstances or environment.
The technology of Japanese Unexamined Patent Publication No. 224064 / 2001 has the problem that setting of reference points is required.
Another problem is that clearly determining an area where calls are forbidden or prohibited is difficult since the GPS accuracy is poor.
Also, GPS cannot be used inside buildings.
The technology of Japanese Unexamined Patent Publication No. 224075 / 2001 has the problem that the user must set the manner mode in order to utilize the scheduling functions, and this is troublesome for the user.
In the technology of Japanese Unexamined Patent Publication No. 326976 / 2001, a processor calculates the movement speed by utilizing GPS, however constant use of GPS consumes much power in the mobile terminal.

first embodiment

[0054]FIG. 1 is an overall concept view showing 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.

[0055]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 th...

second embodiment

[0068]FIG. 4 is a concept diagram showing the cellular telephone system of the present invention. In this embodiment, calls of the cellular telephone present within the designated area are automatically forbidden. The BT device 401 in the figure is installed to prohibit calls in the designated area. This designated area for example is a concert hall 402. The BT device 401 installed in the concert hall 402 inserts communication forbidding information in the format sent after the pilot. The cellular telephone 403a within range of the radio waves of BT 401, or in other words, all cellular telephones 403a in the concert hall receive communication forbidding information so that all the cellular telephones 403a automatically send an answering mode registration request signal, and the telephone sections are set to sleep status (RF section transmission is stopped) so that the cellular telephones 403a cannot make calls. When the cellular telephones 403b is brought outside of the communicatio...

third embodiment

[0072]FIG. 5 is a concept diagram showing the cellular telephone system of the present invention. An example is described for areas allowing calls (communication) and areas where calls are forbidden on a transportation means. In this embodiment, a train is the type of transportation having a train interior 501 where calls are forbidden and a deck 502 where calls are allowed. A BT device 503 is installed with the train interior 501, and this BT device 503 sends communication (call) forbidding information to each cellular telephone 504 in the train interior 504. Along with showing that the area is a communication forbidden area on the display (LCD) 504a of cellular telephone 504, an answering mode registration request signal is sent, and each cellular telephone 504 is set in sleep status. However, a BT device 505 is installed on the deck 502 and a communication allow signal is output from this BT device 505. The cellular telephone 506 in the deck 502 is capable of making calls so can ...

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.

Description

FIELD OF THE INVENTION [0001] 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. DESCRIPTION OF THE RELATED ART [0002] 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...
