Problems solved by technology

Another problem: due to poor GPS accuracy, it is difficult to clearly identify areas where calls are prohibited or blocked
Likewise, GPS cannot be used inside buildings
[0009] The technique of Japanese Unexamined Patent Publication No. 224075 / 2001 has the problem that the user must set the mode mode in order to utilize the scheduling function, which is troublesome for the user
[0010] In the technique of Japanese Unexamined Patent Publication No. 326976 / 2001, a processor calculates the moving speed by utilizing GPS, however continuous use of GPS consumes a lot of power in the mobile terminal

Embodiment Construction

[0053] Hereinafter, embodiments of the present invention will be described with reference to the drawings.

[0054] figure 1 is an overall conceptual view showing the first embodiment of the cellular phone system of the present invention. A cellular phone 1 in the figure exists in a designated area (or designated location) 2 and can communicate with a first base station 3 . When radio waves are transmitted from the cellular phone 1, they are received by the first base station 3 and sent to a cellular phone system server 4 to be transmitted to the other party's cellular phone or Fixed telephone.

[0055] figure 2 is a block diagram showing an embodiment of the overall operation of the cellular phone of the present invention. In this figure, a CDMA (Code Division Multiple Access) signal and a GPS (Global Positioning System) signal received from an antenna 21 are input to a CDMA amplifier 23 or a GPS amplifier 24 through a transmission / reception selector switch 22 and commun...

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

technical field [0001] The present invention relates to a cellular telephone device and a transmitter for transmitting to a cellular telephone, and more particularly to cellular telephone technology and a transmitter for transmitting to a cellular telephone for use at a specified location, time , situation or environment, switch the cellular phone mode to sleep mode or silent mode or answer mode, and automatically disconnect the transmission. Background technique [0002] With the widespread use of cellular phones, there have been problems with the harsh manner in which cellular phones are used and the negative effects from radio waves. For example, in order to prevent disturbing other people while using cellular phones, public transportation systems such as buses and trains have regulations in the compartments of buses or trains requiring passengers to refrain from using cellular phones. However, this requirement is not always complied with. Hospitals and medical clinics ...
