Description

[Detailed description of the invention] [Object of the invention J (Industrial application field) The present invention relates to improvements in radiotelephone equipment.

(Prior Art) Conventionally, there are the following devices as this type of device. Figure 6 shows its configuration.
i! 1, and a wireless telephone 4 connected to the parent device 2 via a wireless line 3.Transmission 1 (TX) 22 and reception II, in which transmission and reception channels are specified. (RX) 23, subscriber line 1 is connected during a call.
After passing through the line relay 24 and the hybrid circuit 25, the call signal received from the other party's terminal is modulated by the transmitter 22 and sent from the transmitting antenna 26 to the radio circuit.
3, and receives a wireless communication signal that arrives from the wireless telephone 4 via the wireless line 3 via the receiving antenna 27.
After demodulating at 23, the signal is sent to the subscriber line 1 via the hybrid circuit 25 and line relay 24.

This parent I device 2 also serves as a circuit necessary for connection between the subscriber line 1 and the wireless telephone 4, and is connected to the
An incoming call detection circuit 28 that detects a Hz calling signal, a received electric field detection circuit (C-DET) 29, and an identification signal detection circuit (
ID-DET) 30 and a control circuit (CONT) 31. Of these, the received electric field detection circuit 29 is comprised of a carrier squelch or noise squelch circuit, and monitors the arrival of radio waves from the wireless telephone 14. The identification signal detection circuit 30 verifies a predetermined identification signal (ID code) by the combination of the parent device 2 and the wireless telephone Ia4, and notifies the control circuit 31 of the verification result.The control circuit 31 , for example, has a microcomputer as the main control unit, and performs occasional connection control. Reference numeral 32 is a rectification and stabilization circuit, which adjusts the predetermined operating voltage V from the commercial power output.
cc is generated and this operating voltage Vcc is supplied to each circuit in the parent device 2, and is also supplied to the wireless telephone 4 via the power supply terminal 33 as a charging voltage.

On the other hand, the wireless telephone III 4 is equipped with a transmitter (TX) 42 and a receiver (RX) 43 for which transmission and reception channels are specified by a synthesizer (SYN) 41, similar to the above-mentioned parent device 2. The incoming wireless communication signal is received and demodulated by the receiver 43 via the receiving antenna 44, and then outputted as voice from the receiver 45, and transmitted to the transmitter 4.
After modulating the speech signal input from 6 at the transmission g142, it is sent to the radio line 3 via the transmission antenna 47. The wireless telephone 4 also includes a transmission switch 48, a circuit necessary for connection between the parent device 2 and the exchange.
Dial key 49, received electric field detection circuit (C-DET>5
0, an identification signal detection circuit (ID-DET) 51, a control circuit (CONT) 52 which uses a microcomputer as a main control unit and performs various connection controls, and a sounder 53 which generates a sound. Furthermore, 54 is a battery;
It is charged by the operating voltage Vcc supplied from the parent device 2 via the charging terminal 55. Further, 56 is a power switch.

In such a configuration, when an incoming call first occurs, the parent device 2 detects the occurrence of this incoming call with the incoming call detection circuit 28, and the control circuit 31 instructs the synthesizer 21 to select a control channel to transmit the signal to the transmitter tI22 and the receiver. 2 are activated to send an ID code and an incoming call signal to the wireless telephone 4. Note that this incoming call signal also includes a signal specifying a communication channel. On the other hand, in the wireless telephone 4, the receiver 43 performs an intermittent reception operation while on standby, and when a radio wave arrives from the master device 2 in this state, it is detected by the received electric field detection circuit 5.
0, and the identification signal detection circuit 51 checks the ID code sent from the parent device i2. If it is determined as a result of this verification that the call is to the own device, the control circuit 52 instructs the synthesizer 41 to select a transmission/reception channel, puts the transmitter 42 and the receiver 43 in a continuous operating state, and then sends an ID code and responds to the incoming call. The signal is sent back to the parent device 2. On the other hand, when the receiving electric field detection circuit 29 detects the arrival of radio waves from the wireless telephone Ia4, the parent device 2 stops sending out the incoming signal, and then checks the ID code in the identification signal detection circuit 30, and if the ID codes match, Transmission 16!22 and reception I! ! 23 is first switched to the communication channel specified for the wireless telephone 4 by the incoming call signal, and then a bell ringing signal is sent out. In response, the radio telephone 4 switches the channels of the transmitter 11142 and the receiver 43 to the communication channel after sending out the incoming call response signal, and then waits for the arrival of the bell ringing signal from the parent device 2, and then this bell ringing signal arrives. Then, the sounder 53 generates a ringing tone to notify the subscriber of the occurrence of an incoming call.

When the subscriber responds to this call by turning on the calling switch 48, the wireless telephone 1114 transmits an off-hook signal from the transmitter 42 to the rice bag H2. On the other hand, when the off-hook signal arrives from the wireless telephone 4 while transmitting the bell ringing signal, the parent device 2 stops transmitting the bell ringing signal and closes the line relay 24 at this point.

Thus, a communication path is formed between the wireless telephone tI14 and the caller, and communication between the two is possible thereafter.

On the other hand, in the standby state, when the subscriber turns on the transmission switch 48 of the radio telephone 4, the radio telephone 4 uses the control circuit 52 to instruct the synthesizer 41 to a specific control channel, thereby transmitting the transmitter 42 and the receiver 43. are operated continuously, and the I[) code and transmission signal are sent to the parent device 2. On the other hand, when a radio wave arrives from the wireless telephone 4, the parent device 2 receives it from a receiving electric field detection circuit 29.
The ID code is detected by the identification signal detection circuit 30. As a result of this verification, when it recognizes that it is a connection request to itself and confirms the arrival of the outgoing signal, the control circuit 31 creates a outgoing response signal and sends this signal from the transmitter 22 along with the communication channel instruction information. Wireless telephone 4
and after this sending, the transmitter 22 and the receiver e1
Switch channel 23 to a voice channel. After this control, the line relay 24 is turned on to close the DC loop of the subscriber line 1. On the other hand, the wireless telephone 4 is connected to the main device 2.
When the transmission response signal arrives from the receiver 1143, the receiver 1143 is operated continuously to switch the channels of the transmitter 42 and the receiver 43 to the communication channel. When the subscriber enters the telephone number of the other party using the dial key 49 in this state, the wireless telephone 4 transmits the key code data from the wireless line 3 to the transmitter a42.
The data is sent to the parent device 2 via. As a result, the control circuit 31 of the parent device 2 controls the opening and closing of the line relay 24 in accordance with the key code data to transmit dial pulses to the subscriber line 1. A call is then made to the desired party, and if the called party responds, a communication path is established between the wireless telephone 4 and the called party, and subsequent communication becomes possible.

That is, if such a device is used, the wireless telephone 4
It is very convenient because you can move around freely and make calls just like a normal wired phone.

However, this type of device is difficult to use when the wireless telephone 4 turns off the power switch 56 for rapid charging, for example, or when the wireless telephone 4 is outside the range where radio waves can be sent and received with the main device 2 (outside the communication area). ), even if an incoming call occurs, the incoming call signal sent from the parent device 2 does not reach the wireless telephone 4, and as a result, a wireless line 3 is formed between the parent device 2 and the wireless telephone 4. Can not do it. Further, even if the wireless telephone 114 is present within the communication area, the wireless line 3 cannot be formed if it is hidden behind something such as a pillar or if fading occurs while moving. In such a case, the parent device 2 repeats sending out the incoming call signal until the incoming call response signal arrives from the wireless telephone 4, and when the incoming call response signal is not returned even after sending out the predetermined number of times, the call signal from the exchange is interrupted. The computer returns to standby mode.

Therefore, when using this type of device, care must be taken to prevent the above situation from occurring, but if the above situation were to occur, conventional devices would Since the system simply returns to the standby state after the call is abandoned, the subscriber has no idea that an incoming call has occurred, and it is difficult to take appropriate responses to incoming calls that occur during that time. I couldn't do it.

(Problems to be Solved by the Invention) As described above, when a call is received when the wireless line cannot be connected, the conventional device does not have to deal with the caller's business, etc. This has the problem that it is impossible to even know that an incoming call has occurred, and it is impossible to take appropriate measures afterwards. Even if a call occurs,
The present invention aims to provide a wireless telephone device that allows not only the occurrence of an incoming call to be known but also information such as the caller's business and the like so that an appropriate response can be taken later.

"Structure of the Invention" (Means for Solving Problems) The present invention provides a wireless telephone device that connects a parent device and a wireless telephone via a wireless line, as shown in FIG.
a wireless line connection determining means B, which has a recording means A built into or externally installed in the parent device, and determines whether or not a wireless line can be connected between the parent device and the wireless telephone when a call is received; and a recorded guidance sending means C; A recording control means is provided, and when the wireless line connection determining means B determines that the wireless line connection is impossible, the recording guidance sending means C responds to the calling party and then records the business. After the guidance information is sent out and the recorded guidance sending means C sends out the guidance information, the recording control means causes the recording means A to record the signal arriving via the wired telephone line. This is the point.

(Function) As a result, even if an incoming call occurs when the wireless line connection is difficult, guidance information is automatically sent to the caller prompting him or her to answer the call and record the message. When the caller speaks his/her business, the voice will be recorded on the recording means A, so the subscriber can later listen to the caller's business by playing back the voice recorded on the recording means A. You can know. Therefore, the subscriber can take appropriate measures according to the caller's requirements.

(Embodiment) FIG. 2 shows the configuration of a wireless telephone device according to a first embodiment of the present invention. In addition, in the same figure, the sixth
Components that are the same as those in the figures are given the same reference numerals and detailed explanations will be omitted.

The parent device 20 newly includes first and second recording/playback circuits 34 and 35, and an incoming call response detection circuit (RC-DET) 36.
This is the provision. The first and second recording/reproducing circuits 34 are composed of, for example, tape recorders or digital recording/reproducing circuits, and the first recording/reproducing circuit 34 is a tape recorder or a digital recording/reproducing circuit.
The caller's voice is recorded and played back. Further, the second recording/reproducing circuit 35 sends a guidance message to the calling party to record the business when it is determined that the wireless line 3 cannot be connected. The incoming call response detection circuit 36 detects the wireless telephone 11i40 after sending out the incoming call signal.
This is to determine whether or not an incoming call response signal has been returned from the incoming call response signal, and if an incoming call response signal is not detected within a certain period of time, a signal to that effect is supplied to the control circuit 311.

Further, the control circuit 311 of this embodiment includes a recording guide sending control means and a recording control means in addition to a wireless line connection control means and a subscriber line connection control means. The recorded guidance sending control means activates the line relay 24 when the incoming call response detection means 36 does not detect an incoming call response from the wireless telephone 4o and therefore determines that the wireless line cannot be connected.
After responding by closing the subscriber line 1, the second recording and reproducing circuit 35 is driven to reproduce the guidance message, and the subscriber line 1
It is to be sent to. The lax recording control means that the first recording and reproducing circuit 34 is operated after the guidance message is sent.
, thereby recording the voice coming from the caller.

With such a configuration, when an incoming call occurs and an incoming call signal is sent to the wireless telephone 40, the parent device 20 monitors whether or not an incoming call response signal has arrived from the wireless telephone 40 using the incoming call response detection circuit 36 in this state. do. If the incoming call response signal is not returned even after repeatedly sending out the incoming call signal a predetermined number of times, it is determined that the connection to the wireless line 3 is difficult, and the mode shifts to recording mode. That is, the parent device 20 first closes the line relay 24, thereby responding to the caller's call, and then reproduces the guidance message from the second recording/reproducing circuit 35 and transmits it to the subscriber line 1. here,
For example, this guidance message may include, ``I am unable to answer the phone at this time, so please wait until you hear the beep sound.''
Please state your request within 0 seconds. A voice message called ``bee'' is used. After the guidance message is sent out, the first recording/reproducing circuit 34 is operated to record the caller's business message to be sent in accordance with the guidance message. Then, when 30 seconds have passed since the start of recording, the recording operation is finished and the line relay 2
4 to return to standby mode. Also, at this time, the control circuit 311 of the parent device 20 stores in the internal memory the fact that the business message has been recorded.

In addition, in this state, when the outgoing signal arrives from the wireless telephone 40 and the signals of the # key and the When it is determined that the message is a playback request, it is first determined from the information stored in the internal memory whether or not the business message has been recorded. If it has been recorded, the first recording and playback circuit 34 is operated, thereby causing the message to be played back. 1
The message is reproduced from the recording/reproducing circuit 34 of the computer and transmitted to the wireless telephone 1140 via the wireless line 3. As a result, in the wireless telephone 11140, the business message received from the parent device 20 is output as voice from the receiver 45, and the subscriber is notified.

Therefore, by listening to this business message, the subscriber can learn about incoming calls that have occurred while the wireless telephone 40 is in a state where calls are not possible.

That is, in this embodiment, when an incoming call occurs and no incoming call response signal is obtained from the wireless telephone 40, the caller is automatically answered and then a guidance message is sent to request recording of the business, Since the message sent from the caller is recorded, even if it is a wireless phone
To automatically record a caller's business even when a power switch 56 of a wireless telephone 1140 is turned off, a wireless telephone 1140 is out of a wireless communication area, or cannot receive radio waves due to fading. Can be done. therefore,
After the wireless line 3 is restored to a connectable state, the subscriber can learn about the caller's business, and can take appropriate action accordingly.

FIG. 3 shows the configuration of a wireless telephone device according to a second embodiment of the present invention. This device includes a wireless telephone 40
1 is provided with a key 57 for generating a power off signal,
By operating this key 57 before turning off the power switch 56, the wireless telephone 401 notifies the parent device 210 that the power will be turned off, and by storing this information in the parent device 201, the incoming call can be stopped. When this occurs, it can be determined from this power-off information that the wireless line 3 cannot be connected.

That is, when the subscriber operates the power-off signal generating key 57 when rapidly charging the battery 54 of the wireless telephone 11401, for example, the control circuit 522 of the wireless telephone 401 is activated.
When this power-off signal generation key 57 is operated, the transmitter 42 is operated to send a power-off signal to the parent device 201, and then the power switch 56 is turned off. On the other hand, upon receiving the power off signal, the parent device 201 stores this signal in the internal memory of the control circuit 312.

When an incoming call occurs in this state, the control circuit 312 of the parent device 201 first determines whether or not a power off signal is stored in the internal memory. It responds by closing the relay 24, and then executes the control for recording the business message mentioned above. Note that when charging of the wireless telephone 401 is completed and the subscriber turns on the power switch 56, a power-on signal is sent from the wireless telephone 401 to the parent device 201, and the serial control circuit 312 of the parent device 201 stores it in the internal memory. Clear a certain power off signal.

With such a configuration, when the power switch 56 of the wireless telephone 401 is turned off, the master device 201 immediately automatically answers an incoming call without sending an incoming signal and enters the message recording mode. Since there is no need to send out unnecessary radio waves, and there is no need to respond to incoming calls from the wireless telephone 13t401 for a certain period of time, it is possible to shift to recording the message in a short time, thereby reducing the sense of discomfort to the caller. can be reduced.

In this embodiment, a power off signal generation key 57 is provided to send a power off signal to the parent device 20'1.
Alternatively, a capacitor for holding the electric voltage may be provided to maintain the operation of the radio telephone 401 for a certain period of time after the power switch 56 is turned off, and a power off signal may be generated and sent to the parent device 201 during this period. good.

The status display control means notifies the wireless telephone 402 that a message has been recorded and displays it on the display 58.

That is, when a power-on signal arrives from the wireless telephone 402 which was in the power-off state while the business message is being recorded in the first recording/playback circuit 34, the control circuit 313 of the parent device 202 transmits the message to the wireless telephone 11402. Sends a signal indicating that the message is being recorded. As a result,
Display 58 of wireless telephone 402 lights up or flashes after power is turned on. Therefore, the subscriber can know from this display 58 that an incoming call has occurred during the power-off period of the radio telephone 402, and thereby, for example, the subscriber can receive a call from the sta telephone 402 as described in the first embodiment. When a request is sent, the business message recorded in the first recording/playback circuit 34 of the parent device 202 is played back and the wireless telephone t14 is sent.

In addition, the above control operations can be performed other than when the power is turned on.
This can also be done when a calling operation is performed on the wireless telephone 11402 or when an incoming call occurs on the parent device 402. In this case, for example, by inserting or adding information to the effect that a business message has been recorded in a connection control signal accompanying an outgoing/receiving call, the main device 202 can send the message to the wireless telephone 4.
02 and drive the display 58.

Furthermore, this may be done when the subscriber inputs a confirmation request on the wireless telephone 402, or if a message is recorded, the parent device 202 may periodically send a display signal to the wireless telephone 402. It may also be displayed.

With this embodiment, it is possible to more reliably notify the subscriber of the wireless telephone 11402 that the caller's message has been recorded. In addition to the light emitting diode, the message may be displayed as it is on a dot display as a means of displaying that the message has been recorded.Also, a voice synthesis circuit may be used to record the message. The sounder 53 may output a voice message indicating that the message is being recorded.

FIG. 5 shows the configuration of a wireless telephone device according to a fourth embodiment of the present invention. This device is designed to provide various conveniences in use by providing a plurality of function buttons. That is, the wireless telephone 11403 is provided with a recording/playback request button 59, and this recording/playback request button 5
9 and then a predetermined key in the dial keypad 49, the second recording/playback circuit 35 of the parent device 203 is activated.
is set to the recording mode, and in this state, if the subscriber inputs a desired voice message from the transmitter 46 of the radio telephone 403, this message will be recorded in the second recording and reproducing circuit 35 as a guidance message. Further, when the above-mentioned recording/playback request key 59 is pressed and then another dial key is pressed, the first recording/playback circuit 34 of the parent device 203 enters the playback mode. The message is sent to wireless telephone 403 and output from receiver 45.

On the other hand, the parent device 203 has a playback button 38 and a recording button 3.

When the playback button 38 is operated, the first recording/playback circuit 34 enters the playback mode, and the business message played from this circuit 34 is amplified by the amplifier 60 provided in the parent device 203 and then amplified from the speaker 61. Output. When the recording button 39 is operated, the second recording/playback circuit 35 enters the recording mode, and in this state, when the subscriber inputs a voice message from the microphone 62 provided in the parent device 203, this voice message is amplified by the amplifier 63. After that, it is supplied to the second recording/reproducing circuit 45 and recorded as a guidance message. That is, these play buttons 38
By operating the recording button 39, the user can listen to the business message and record the guidance message using the parent device 293 without using the radio telephone 403. Further, when the manual recording button 64 is operated, the operation signal of this button 64 is supplied to the control circuit 314 through the OR circuit 65 together with the detection signal of the incoming call response detection circuit 36. Therefore, the fill 1!11 circuit 314 automatically answers the caller and then shifts to the control for recording the caller's message as described above. However, the first
The caller's message is recorded in the recording/reproducing circuit 34 of the caller. That is, by operating the manual recording button 64, the caller's message can be recorded even when the wireless telephone 403 is available for response. For example, if a subscriber uses a wireless phone! If the parent device 1203 is far away from 14403 and cannot respond immediately, and the parent device 1203 is nearby.
If there is, the user can operate the manual recording button 64 to record the caller's message for the time being, and later take appropriate action in response to the message. Note that the display 37 provided in the parent device 203
When the first and second recording/reproducing circuits 34 and 35 are recording, they light up or blink to notify the user that recording is in progress.

Note that the present invention is not limited to the above embodiments.

For example, in the above embodiment, the wireless line 3
However, there are cases where an incoming call response is detected but the ID code is not received or does not match, or a bell ringing signal is sent for a certain period of time. Even if an off-hook signal does not arrive even after the off-hook signal is received, it may be determined that the wireless line connection is not possible and the mode may be shifted to the business recording mode. Furthermore, even after it is determined that the wireless line 3 cannot be connected and the mode is shifted to business recording mode, the parent device continues to send an incoming call signal or a bell ringing signal to the wireless telephone, and in this state, an incoming call response signal is not sent back. or when an off-hook signal arrives, the business recording mode may be interrupted and the connection with the wireless telephone may be established, thereby allowing a conversation to take place. In this way, for example, even if the radio waves are temporarily cut off due to fading or the like during incoming call connection control and the mode is shifted to business recording mode, it is possible to switch to a telephone call when the radio wave state returns to normal. Furthermore, in each of the above embodiments, the mode is shifted to the message recording mode only when it is determined that the wireless line cannot be connected. However, for example, by providing a mode changeover switch and operating this changeover switch, the wireless line It may also be possible to shift to the business recording mode even if connection is possible. Furthermore, there is no need to provide separate recording means for recording and reproducing guidance information and for recording and reproducing business messages; for example, by dividing the recording area of the tape and using it, a single tape recorder can be used. Good too. In addition, the configurations of the recording means, the wireless line connection determining means, and the recording guide sending means, the control procedure and control contents of the recording control means, etc. can be modified in various ways without departing from the gist of the present invention.

[Effects of the Invention] As detailed above, according to the present invention, recording means is built in or installed externally in the main unit, and when a call is received, it is determined whether or not a wireless line can be connected between the main unit and the wireless telephone. A wireless line connection determining means for making a determination, a recorded guidance sending means, and a recording control means are provided, and when the wireless line connection determining means determines that the wireless line connection is impossible, the recorded guidance sending means issues a message. After answering the call party, sending guidance information urging the caller to record the business, and after the guidance information is sent by the recording guidance sending means, a signal arrives via the wired telephone line by the recording control means. By having the above-mentioned recording means record the information, even if an incoming call occurs when the wireless line cannot be connected, the user can know not only the occurrence of the incoming call but also information such as the caller's business. This makes it possible to provide a wireless telephone device that allows appropriate measures to be taken later.
