<Example>

As shown in FIG. 2, the battery 10 supplies power to a cellular phone and a PCS terminal, and the wireless call function unit 20 performs two-way communication with the exchange side to inform the exchange side of the terminal's current position. In this case, when a signal recognized at an exchange (not shown) is applied through the receiving unit 30, the position signal of the current terminal is applied to the exchange side through the transmitting unit 40, and the receiving unit 30 itself at the counterpart terminal. Receives a signal received through the exchange from the duplexer 50 when a call is made to the terminal of the terminal, and the transmitter 40 applies a transmission signal to the exchange side through the duplexer 50 when the user calls the terminal of the other party. The duplexer 50 applies a received signal applied from the exchange to the terminal, or transmits a transmission signal from the terminal to the exchange, and the MCU 60 sends to the receiver 30 and the transmitter 40. When the emitter signal is not applied to the low signal to the switching section 70 in order to minimize the power consumption of the battery, the switching section 70 in accordance with the high signal or low signal applied from the MCU (60) An electric current is applied to the line connected to the keypad 80, and the keypad 80 is engraved with the telephone number so that the user can make a telephone call.

Hereinafter, the operation of the present embodiment configured as described above will be described in detail with reference to the accompanying drawings.

First, as shown in FIG. 2, when there is no signal received from the terminal of the other party for a predetermined time, that is, a signal applied to the MCU 60 through the duplexer 50 and the receiver 30 from the base station shown in FIG. If not present, the MCU 60 stops the operation of the transistors Q1 and Q2 by applying a low signal to the base terminal of the transistor Q1 of the switching unit 70. The power applied to the line connected to the power supply is cut off to cut off the power applied to an unnecessary place, and FIG. 1 is a view showing the overall signal flow between the terminal and the terminal.

Meanwhile, since a low signal is applied from the MCU 60 and the switching unit 70 is cut off, the received signal from the base station shown in FIG. ), The duplexer 50 separates the received signal and applies the received signal to the receiving unit 30. The receiving unit 30 receiving the received signal from the duplexer 50 indicates that the received signal exists. In order to notify), the received signal is applied to the MCU 60.

The MCU 60 receiving the signal from the receiving unit 30 applies a high signal to the switching unit 70 and the switching unit 70 receiving the high signal from the MCU 60 Start applying power to the line connected to it.

As shown in FIG. 3, the base station cell receives the position response signal of the terminal a and registers it in the mobile visitor position register using the position information. The passage of the terminal (b) and the terminal (a) is connected so that voice or information can be exchanged with each other.

On the other hand, when the user presses the keypad 80 in a state in which a low signal is applied from the MCU 60 and the switching unit 70 is cut off and the power applied to an unnecessary portion of the terminal is suspended, the input through the keypad 80 is performed. The signal is applied to the MCU 60, and the MCU 60, which receives the signal from the keypad 80, applies a HIGH signal to the switching unit 70 so as to prevent the power consumption. Start applying to the line connected to.

remind As shown in FIG. 4, the terminal a transmits the location information signal through the transmitter 40 and transmits the number of the counter terminal b. Receives the position response signal and then updates the visitor register. Using the location information, the exchange station connects the path (PATH) of the counterpart terminal b and the mobile terminal a to exchange voice or information with each other.

On the other hand, when the MCU (60) outputs a low signal to the switching unit 70, the communication between the terminal and the base station, the radio call function unit 20 shown in FIG. It will work.

That is, as shown in FIG. 3, when the counterpart terminal b transmits a location request signal while the terminal a has suspended power, the terminal a receives a location request signal using a two-way radio pager and then positions the device. At the same time as the information is transmitted, the terminal a is switched to the on mode. At this time, the base station cell receives the response signal from the terminal and registers it in the mobile visitor location register. Using this position information, the exchange station connects the path between the counterpart terminal b and the terminal a to exchange voice or information. To help.

In addition, as shown in FIG. 4, the user terminal receiving the call from the base station transmits the location information signal to the mobile terminal a and transmits the number of the counterpart terminal b to the transmitter 40 and the duplexer shown in FIG. 2. 50), the base station cell receives the position response signal and updates the visitor register. Using this location information, the switching center connects the passage between the counterpart terminal b and the mobile terminal a.
