Detailed description of the mobile phone reception control apparatus and control method of the present invention will be described with reference to the accompanying drawings.

1 is a schematic block diagram of a mobile phone reception control apparatus and a control method according to the present invention, and a signal processing unit 120 for processing RF signals received through an antenna 110 and converting them into intermediate signals. A demodulation unit 130 for receiving and demodulating an intermediate signal received from the signal processing unit 120 or receiving and modulating a signal received from the DTMF generator 140 and the codec unit 160; Codec unit 160 for coding or decoding the audio signal input and output between 130 and audio amplifier 170 under the control of system controller 150, and the voice signal applied from microphone 172. Receives the amplified signal, amplifies it, and outputs the audio amplifier 170 to the codec unit 160, a system controller 150 for controlling all operations of the process, and various kinds of information according to the control of the system controller 150. Display to DISPLAY The unit 182, the memory unit 152 for storing various kinds of information required by the mobile phone under the control of the system controller 150, the phone number, various functions, etc. under the control of the system controller 150 Under the control of the keyboard unit 186 and the system control unit 150 to input the signal output from the electromagnetic wave blocking transmission unit 192 installed outside to switch the mode of the mobile phone to the vibration mode or the power-off mode The electromagnetic wave blocking receiving unit 190 is controlled.

The antenna 110 is a dual antenna that can receive a signal of a radio frequency band of the mobile phone and another radio frequency band for receiving the signal of the electromagnetic wave blocking transmitter 192.

The microwave blocking receiver 190 is a state in which a signal output from the electromagnetic wave blocking transmitter 192 is unilaterally received, and the electromagnetic wave blocking transmitter 192 is typically installed at an entrance through which a person enters or exits, such as a theater, a hospital, a court, and the like. The data is transmitted and received wirelessly between the electromagnetic wave blocking receiver 190 and the electromagnetic wave blocking transmitter 192. In this case, the frequency used is a frequency band of a high frequency different from the frequency band used in the mobile phone. It can also be used using infrared rays.

That is, the frequency band used at this time is usually preferably about 300 to 500MHz.

Reference numeral 174 is a speaker and 186 is a keyboard.

As shown in FIG. 2, the operation of the present invention is performed by the user turning on the power (S100), after performing the step (S100), and initializing (S200), and performing the step (S200). After receiving the signal from the electromagnetic wave blocking transmission unit 192, and switching to a predetermined mode, and setting the contents of the waiting time and the like (S300), and after switching to the constant setting mode by the step (S300) the user is a mobile phone Receiving a signal received from the electromagnetic wave blocking transmitter 192 installed in a theater or the like (S400), and receiving the signal output from the electromagnetic wave blocking transmitter 192 in the step (S400). In step S410, if the received signal is an odd number, if the received signal is an odd number, and proceeds to the next step (S900), and in the step S410, the electromagnetic wave blocking transmitter 192 ) When the signal output from the odd number is the step of checking whether the user is busy (S500), and if the user is busy by the step (S500) received the received signal from the electromagnetic wave blocking transmitter 192 to the user Therefore, the step S600 of displaying the contents of the transition mode to the constant state and the contents of the transition to the constant mode are displayed by the step S600, and then a predetermined waiting time elapses after the setting in the step S300. Switching to the switching state (S700), and if the user exits the theater after switching to the switching state (S700), receiving the output signal from the electromagnetic wave blocking transmitter 192 again (S800); When receiving the signal output from the step (S800) to check whether the received signal is even-numbered to perform the next step in the even-numbered, if the odd-numbered The step (S810) of performing the step (S500), and when receiving the signal output from the electromagnetic wave blocking transmitter 192 from the step (S810) (S820) and the step ( After being displayed by the step S820 and immediately switching to a state before the step S400 (S900).

In the step (S300) is set to a certain specification when the mobile phone is released for the first time, if the user wants to set to a different state can be set to a new state.

For example, when it is released from the company, upon receiving the signal output from the electromagnetic wave blocking transmitter 192, the vibration mode and the standby time may be set to 5 seconds, and the user modifies the setting state to block the electromagnetic wave. When the signal from the transmitter 192 is received, the power can be turned off and the standby time can be 10 seconds.

However, the waiting time can be varied according to a normal situation, but the maximum extension time is preferably about 5 seconds to 10 seconds considering the case of the call.

In addition, in step S410, after receiving the received signal output from the electromagnetic wave blocking transmitter 192 at the antenna 110, the signal processing unit 120 and the modulation and demodulation unit 130 perform a predetermined process and then the electromagnetic wave blocking receiver ( When received at 190, the electromagnetic wave blocking receiver 190 applies the signal output from the electromagnetic wave blocking transmitter 192 to the system controller 150, and the system controller 150 inputs the signal. The signal output from the electromagnetic wave blocking transmission unit 192 is stored in the memory unit 152 by being applied to the memory unit 152 and the signal output from the electromagnetic wave blocking transmission unit 192 is stored in the system control unit 150. The number of times entered is determined.

In operation S600, the signal output from the electromagnetic wave blocking transmitter 192 is displayed externally so that a user may know when receiving the signal, and the antenna 110 receives the signal received from the electromagnetic wave blocking transmitter 192. When the signal processing unit 120 and the modulation and demodulation unit 130 receives a predetermined process after receiving a signal from the electromagnetic wave blocking receiver 190, the electromagnetic wave blocking receiver 190 outputs the signal from the electromagnetic wave blocking transmitter 192. Is applied to the system controller 150, and the system controller 150 receives such a signal and applies the signal to the display unit 182 so that the user can be displayed to the outside.

In the step S900, the user is to maintain the state before the step S400. For example, when the state before the step S400 is the melody state when receiving the mobile phone, the melody state is a vibration state. In the case of a vibration state, and in a power off state, it is kept in a power off state.

Mobile phone reception control device and control method of the present invention configured as described above, the mobile phone that most people carry a cell phone in a public place, such as a hospital, court, lecture room, etc. do not operate to inconvenience the surrounding people inconvenience It is designed to be able to maintain the state that suits the characteristics of public places.
