FIG. 1 shows an embodiment of the mobile telephone grftft of the present invention. In the figure, a parent device 1 is connected to a wireless telephone 12 via a wireless line, and is also connected to a wired telephone line 3.

Now, when the line relay 33 is turned on and in a talking state, the signal sent from the voice line 3 becomes the modulation input of the transmitter 5 via the line relay 33 and the hybrid circuit 4. Radio waves modulated by the transmitter 5 are sent to the radio telephone 2 from the transmitting antenna 6.

On the other hand, radio waves transmitted from the S-less telephone 2 are received by the receiving antenna 7 of the parent device 1 and demodulated by the receiver 8. The demodulated signal is sent to the hybrid circuit 4 and line relay 3
Right 1% through 3! It is sent to telephone line 3.

Synthesizer 9 outputs a signal of a frequency corresponding to the wireless channel (communication channel and control channel) to transmitter 5 and receiver n8. Note that, as the wireless channel, one of one control channel and a plurality of communication channels is selected.

One of the outputs of H4i!18 is the received electric field detection circuit 1.
0 and used for determining the electric field strength.

This circuit 10 is generally called a carrier squelch circuit or a noise squelch circuit. Another output is output as a data signal included in the received demodulated wave,
The signal is input to an identification signal detection circuit 11 that checks the identification @ number determined by the combination of the parent device 1 and the wireless telephone 2, and the identification signal is checked. This identification signal is generally called an ID code.

The outputs of these detection circuits and the demodulated output of the data signal are input to the control circuit 12 and used for connection control. Furthermore, this control circuit 12 performs wireless channel switching control by controlling the synthesizer 9, and controls the transmitter 5.
Control is performed such as sending out the transmission data signal as a modulation input. Also, the wired line 1 is detected by the 16H2 detection circuit 30.
It is detected whether or not there is an incoming call from 3, and the control circuit 12
The incoming call is determined based on the detection output of this circuit.

On the other hand, the radio telephone 112 is similarly provided with a reception antenna 13 and a reception 1114, and the demodulated output of the receiver 14 is output to the receiver 15. Further, the voice input from the transmitter 16 becomes a modulation input to the transmitter 17, and radio waves are transmitted from the transmitting antenna 18.

Synthesizer 19 and received electric field detection circuit 20 in the S-less telephone 2. The identification signal detection circuit 21 is equivalent to the parent device 1, and is controlled! The Ill channel 22 provides overall control of the wireless telephone 2. The speaker 23 is a sounder that emits a ringing tone when a call arrives.

In these power supply systems, the main mounting ¥11 is AC-100V.
Connect the AC plug 24 to 11! The output of the current stabilizing circuit 25 is used in each circuit. Further, this output is supplied to a rechargeable battery 29 of the radio telephone 2 via the current control resistor 26 and charging terminals 27 and 28, and the output of the battery 29 is used as a power source for the radio telephone 2.

Next, the calling operation of this radio telephone device will be described.

When the hook switch 31 is turned on when making a call from the non-IQ telephone 2, the control circuit 22 detects this and causes the Hokko diode 34 to blink. This allows the user to send
You can tell that the vJ work has started. At the same time, the control circuit 22 determines that the hook switch 31 is turned on, so that the FIL-free telephone 2 should shift from the standby state to the outgoing operation, locks the oscillation frequency of the synthesizer 19 to the control channel, and then transmits the signal to the receiver 14. Turn on and receive radio waves on the control channel. and,
The electric field strength of the received radio waves in the control channel is detected by the detection output of the received electric field detection circuit 20. As a result, if there is no received field strength above a certain value, the control circuit 22 determines that this control channel is vacant, and transmits 117
is turned on to cause this radio telephone 2 to transmit a calling signal containing the assigned 10 code. In the parent device 1 that has received this outgoing signal, the identification signal detection circuit 11 determines whether or not the II) code included in the outgoing signal matches the ID code that has been cut out for the combination with the wireless telephone 1112. If they match, the control circuit 12 turns on the transmitter 5 and sends a response signal (including code 10 and call channel designation information) to the wireless telephone 2.
to be sent.

The wireless telephone m2 receives the response signal from the parent device 1 on the control channel, and uses the identification signal detection circuit 21 to determine whether the 10 codes contained therein match its own.
If they match, the control circuit 22 switches the oscillation frequency of the synthesizer 19 to the frequency of the communication channel designated by the parent device 1. On the other hand, in the parent device 1, after transmitting the response signal, the control circuit 12 switches the oscillation frequency of the synthesizer 9 to the frequency of the call channel designated for the call. As a result, the parent device 1 and the Rem Rai phone 2 are connected through the communication channel designated by the parent device 1. In the parent device 1, after transmitting the response signal, the control circuit 12 turns on the line relay 33 to
A DC loop of the PJ telephone line 3 is formed.

At this time, in the radio telephone 2, after switching the oscillation frequency of the synthesizer 19 to the frequency of the communication channel, the control circuit 22 causes the light emitting diode 34 that had been blinking to continuously emit light. Here, from the start of the call, the parent device 1 and the wireless phone 1
It takes 1 to 2 seconds for a wireless line of a communication channel to be established between 12 stations. Therefore, light emitting diode 3
4 blinks for 1 to 2 seconds from the start of the call until the radio line of the communication channel is configured, and then lights up continuously when the radio line of the communication channel is configured. Therefore, the user can sense that the wireless line of the call channel is being configured by the blinking of the light emitting diode 34, and can also sense that the wireless line of the call channel has been configured by the continuous light emission of the light emitting diode 34. Can be done.

No l here? j When the dial number of the called party is specified by operating the dial key 32 of the telephone 2, this dial number is transmitted from the wireless telephone 2 to the parent device 1,
Furthermore, the dialed number is sent from the parent device 1 to the right If;A telephone line a3. This completes the calling operation.

In this embodiment, the light emitting diode 34 blinks and emits light continuously to indicate that the wireless line of the communication channel is being configured or has been configured, but the present invention is not limited to this. , a plurality of light emitting diodes having different emitting colors may be provided, and by lighting up any one of these light emitting diodes, it may be displayed that the wireless line of the call channel is being configured or has been configured. .
