and a wireless receiving means 23 and a wireless transmitting means 24 of the mobile station 3
constitute wireless transmitting/receiving means 80 and 81 for transmitting and receiving control data and voice signals for communication via the wireless line 4, respectively.

Next, the operation of the above embodiment will be explained. In Figure 1, in steady state (standby state), relays A and B
, C are in the state shown in FIG. 1, respectively. When a call is received from the telephone line in this state, the ringer 6 rings, the call is detected by the incoming signal detection means 7, and an output signal indicating the call state is input to the control means 5.

In this case, the control means 5 stores a program from step 35 to step 78 corresponding to the flowcharts shown in FIGS. 2 and 3, and processes based on this flowchart are performed. When the mobile station 5 detects an input signal indicating the ringing state of the incoming signal detecting means 7, it drives the wireless receiving means 16 and the wireless transmitting means 17 to transmit an incoming command to the mobile station 3 indicating that there is an incoming call.

This incoming command is sent to the wireless transmitting means 17, the antenna 21,
The signal is input to the control means 22 of the mobile station 3 via the radio line 4, the antenna 34, and the radio reception means 23. (Hereinafter, this communication route will be referred to as an upstream communication route). When the control means 22 detects an incoming call command from the wireless reception means 23, it drives the ring tone transmission means 29. Then, a ringing signal is output from the ringing tone sending means 29 and the amplifying circuit 31. A ringing tone is output through the speaker 32.

When in this ringing tone output state, the control means 5 monitors the response at the base station 2, the response at the mobile station 3, the end of the call, and the automatic response time in steps 37, 38, 39, and 40, that is, When an output indicating an off-footer is detected from the handset state detection means 9, the handset call is made at the base station 2, and a termination command indicating the end of the operation is sent to the control means 22 via the upward communication path, and the termination command is received. The control means 22 stops the ringing tone sending means 29 and stops outputting the ringing tone (step 37.53.
54).

When a call is input from the operation unit 33 of the mobile station 3, the control means 22 of the mobile station 3 transmits a call command indicating that there is a call, stops the ring tone sending means 29, and stops outputting the ring tone. The 0 call command is sent to the wireless transmitting means 24.
, through the antenna 34, the radio line 4, the antenna 21, and the radio receiving means 16, and is input to the control means 5 of the mobile station 3 (hereinafter, this communication path will be referred to as the downlink communication path). When a communication command is received, relay A
is turned on to close the line and shift the mobile station 3 to talk mode (steps 38, 55, and 56).

In handset call mode, the audio signal sent from the telephone line is sent to line connection terminal 1, switching contact a.
, the voice is output to the receiver 8a through the telephone call circuit 15, and the voice input from the microphone 8b is sent to the telephone line via the telephone call circuit 15, the switching contact a, and the line connection terminal 1, so that a telephone conversation is possible.

In the mobile station call mode, a voice signal sent from the telephone line is output to the receiver 27 via the line connection terminal 1, the switching contact a, the call circuit 15, the uplink communication path, and the amplifier circuit 25, and is output from the microphone 28. The input voice is transmitted to the telephone line via the amplifier circuit 26, the down communication path, the telephone call circuit 15, the switching contact a, and the line connection terminal l, so that a telephone call is possible.

In step 39, when the control means 5 detects that there is no more output indicating the calling state, it sends a termination command to the mobile station 2. The control means 22 that received the termination command through the uplink communication path stops the ringing tone sending means 29,
Stop outputting the ringtone.

In step 40, when the control means 5 detects that the automatic response time has elapsed, in step 41 it stops outputting the ring tone by transmitting a termination command through the uplink communication path,
In step 42, relay A is turned on to close the line,
By driving the response sending means 13 in step 43,
A response message is sent to the telephone line via the telephone call circuit 15, the switching contact a, and the line connection terminal 1.

When in this state of sending a response message,! l1m means 5
monitors the output of the control signal detection means 10, the response at the base station 2, the response at the mobile station 3, and the response message in steps 44, 45, 46, and 47. When an output indicating the end of the response message is detected from the response sending means 13 in step 47, the message recording means 14 is driven in step 48, and the caller's message is recorded at the line connection terminal 1 and the switching contact a.
, the message is recorded in the message recording means 14 via the communication circuit 15.

When in this business recording state, the control means 5 detects the control signal detection means 1 in steps 49.50.51.52.
0, the response at the base station 2, the response at the mobile station 3, and the output of the call end detection means 12 are monitored. In step 52, when an output signal indicating the end of the call is detected by the call end detection means 2, the message recording means 14 is stopped in step 57, and relay A is turned off in step 58. As a result, recording of the message is completed and the telephone line is released.1. Returns to the state of detecting the presence or absence of a call (steady state).

While sending a response message or recording a message,
When the handset 8 goes off-hook and there is a call input from the operating unit 33, the system shifts to the respective call mode after completing each operation, similarly to the ringing tone output state.

When a control signal, for example a DTMF signal, is sent from the caller while a response message is being sent (or while a message is being recorded), it is detected by the control signal detection means 10,
An output signal indicating the presence of a control signal is input to the control means 5 and the terminal designation code detection means J1. When the control means 5 detects the output signal indicating the presence of a control signal from the control signal detection means 10 in step 44 (or step 49), the control means 5 sends the answer sending means 13 (or message recording means] 4) in step 59. Then, in step 60.6, the output signal of the terminal designation code detection means 11 is monitored.

The terminal designation code detection means 11 is the control signal detection means 10.
When an output signal indicating the presence of a control signal is detected, detection of a terminal designation code sent from the calling party is started, and when a terminal designation code is detected, the terminal designation code is outputted to the control means 5.

If the terminal designation code from the terminal designation code detection means 11 is not input even after the terminal designation code input waiting time has elapsed, the control means 5 drives the special ring tone transmission means 18 in step 63 to perform a relay. B is turned on, a special ring tone is output from the base station 2 via the amplifier circuit 19 and the speaker 20, and is sent to the telephone line via the communication circuit 15, the switching contact a, and the line connection terminal 1, as well as the uplink communication path. As a result, a special ringing command for outputting a special ringing tone is transmitted to the control means 22. The control means 22 that has received the special ringing command drives the special ringing tone sending means 29, turns on the relay -C, and transmits the special ringing tone to the amplification circuit 31.
, is output from the mobile station 3 via the speaker 32.

Further, when the control means 5 detects a terminal designation code indicating selection of the base station 2, it drives the special call sending means 8, turns on the relay B, and sends a special ring tone to the base station 2 and the telephone line. output (steps 6062, 64), and when a terminal designation code indicating selection of the mobile station 3 is detected, the special ring tone sending means 18 is driven to send a special ring tone to the telephone line and also issue a special ring command. vI control means 22.

In this case, the control means 22 turns on the relay C to output a special ring tone from the special ring tone sending means 30 via the amplifier circuit 31 and the speaker 32 (steps 60, 62, 6).
5).

When in these special ring tone output states, the control means 5
If both the base station 2 and the mobile station 3 are outputting a special ring tone, in steps 66, 67, and 6869, the response at the base station 2, the response at the mobile station 3, the output of the end of call detection means 12, The elapse of the special ring stop time is monitored, and if only from the base station 2, the response at the base station 2, the output of the end of call detection means 12, and the elapse of the special ring stop time are monitored in steps 73, 74, and 75. Do the following. On the other hand, if only from the mobile station 3, the responses at the mobile station 3, the output of the end of call detection means 12, and the elapse of the special ring tone stop time are monitored in steps 176, 77, and 78.

When both the base station 2 and the mobile station 3 are outputting a special ring tone, when the control means 5 detects that the special ring stop time has elapsed (step 69), the control means 5 outputs the special ring tone in step 70. Stops the ringing tone sending means 18, turns off the relay B, stops outputting the special ringing tone from the base station 2 and sending it to the telephone line, and transmits a termination command to the control means 22 via the upstream communication path. . Upon receiving the termination command, the control means 22 stops the special ring tone sending means 29, turns off the relay C, and causes the mobile station 3 to output a special ring tone.

Further, when the control means 5 detects that the special ring stop time has elapsed and only the base station 2 is outputting the special ring tone (step 75), the control means 5 outputs the special ring tone in step 70. The sound sending means 18 is stopped, the relay B is turned off, and the output of the special ring tone from the base station 2 and the sending to the telephone line are stopped. In the case of only mobile station 3 (
Step 78), in step 70, the special ring tone sending means 18 is stopped to stop sending the special ring tone to the telephone line, and an end command is sent to the control means 22 to move the special ring tone. Stop the output from station 3.

As described above, when the control means 5 detects the elapse of the special ring tone stop time and terminates the special call, the control means 5 becomes ready to receive a control signal again, and the control means 5 The output of the end of call detection means 12 is monitored (steps 71 and 72).

On the other hand, if the control means 5 detects the off-footer of the handset 8 while outputting the special ring tone (step 66 or step 73), the special ring tone is stopped in steps 53 and 54, and the handset of the base station 2 is output. enable calls,
If a call command is received from the control means 22 (step 67 or step 76), step 55.56
The special ring tone is stopped and the mobile station 3 is enabled to make a call. If the end of the call is detected (steps 68, 74, 77), the special ring tone is stopped in step 57, 58, the telephone line is opened, and the state of detecting the presence or absence of a call (steady state) is established. return.

Effects of the Invention As is clear from the above embodiments, the present invention allows the caller to select the output of the special ringing tone from both the base station and the mobile station, or only one of them. Even when the users of the base station and the mobile station are different, the so-called selective response function, in which only a specific person can respond, can be fully utilized.
