PURPOSE:To securely transmit a message without a special operation by automatically calling a dial for message reproduction when a telephone system becomes enabled calling, discriminating the presence or absence of the message by the message from a base statin and informing a caller of the message only when there is the message. CONSTITUTION:When a control part 9 judges that the power of the system is supplied or that the system comes into a call possible range, the control part 9 automatically calls the dial for message transmission through a modulator 4, a high frequency part 7 and an antenna 8. A DTMF receiver 6 detects whether the message is registered or not, and it is informed to the caller with a reception speaker 2 by an alarm.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a telephone device, and more particularly to a telephone device suitable for effectively using a message reproducing dial in a car phone or a mobile phone.

[0002]

2. Description of the Related Art In recent years, car telephones, mobile telephones, etc., have been providing answering service for answering machines when they are out of the service area or when the caller is absent and the power is turned off. There are many things.

In this answering machine message service, the message is stored in the base station, and the caller can hear the message by calling the message reproducing dial. When entering or when the power is turned on, the message reproduction dial is called to call the base station. Then, when there is a message, the message stored in the base station is heard through the telephone device, and when there is no message, a guide indicating that there is no message is heard from the tape of the base station.

[0004]

Since the conventional telephone device is constructed as described above, when the power is turned on or when the mobile phone enters the coverage area, the message playback dial is called to determine whether there is a message. It is very inconvenient to know. And when there are few normal messages, you will hear the tape guidance that there is no message even if you make a call to hear the message, which is not only very annoying, but often calls to the message playback dial. I will neglect.

In particular, in the case of a car telephone, it is necessary to stop the car to make a call, and it is difficult to know whether or not the driver is in the call range, such as when the driver is at the boundary with the call range, and the call can be made. Every time it seems to enter the area, it is necessary to stop the car and call the message playback dial, which is hardly practical. However, if the call to the message playback dial is neglected due to the annoyance, there is a possibility that an important message will be missed next time, so the service of the message playback dial will not be effectively utilized. I will end up.

As described above, the conventional telephone device is very inconvenient because it is necessary to confirm the presence or absence of the message recorded in the message storage device at the base station side by making a call. The development of means of communication has been a major issue.

The object of the present invention is to solve the above-mentioned problems of the prior art, and when the power is turned on or when a call is made, the decision is made and the message reproduction dial is automatically called to make a call from the base station. It is to provide a telephone device capable of surely transmitting a message without any special operation by determining the presence or absence of a message by the message and notifying the caller of the message only when there is a message.

[0008]

In order to achieve the above object, the present invention provides a call availability determination means for determining whether the power of the device is turned on or the device enters the communication range and becomes available for communication. A message is registered in the message reproducing dial connected to the message reproducing dial and the message reproducing dial in the base station when it is judged that the communication is possible. (EN) A telephone device provided with a message discrimination means for discriminating the presence / absence of a message indicating whether or not there is a message, and an informing means for notifying a caller of this based on the output of the message discrimination means.

[0009]

In the above-mentioned means, the telephone device of the present invention, when the call enable determination means determines that the power supply of the device has been turned on or the device has entered the communication range and is ready for communication, the calling device determines the base station. A message is automatically called to the message reproduction dial in the station, and it is judged by the message judgment means whether or not the message is registered in the connected message reproduction dial, and it is judged that there is a message by the message judgment means. The notification means notifies the caller of this and prompts the listener to listen to the message.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS A telephone device according to the present invention will be described below with reference to the drawings, taking a car telephone as an example.

FIG. 1 is a block diagram showing the configuration of the car telephone of this embodiment. In the figure, the signal received by the antenna 8 is sent to the demodulator 5 via the high frequency unit 7.
The demodulator 5 demodulates the transmitted signals of the base station and the partner station and supplies them to the receiving speaker 2. The DTMF (Dual Tone Multi-Frequency) signal in the demodulated signal is D
It is detected by the TMF receiver 6 and sent to the control unit 9 such as a CPU.

On the other hand, the signal from the transmitting speaker 1 is modulated by the modulator 4 and then transmitted from the antenna 8 via the high frequency section 7. At this time, the control unit 9 interprets the input from the operation keys 3, supplies a control signal corresponding to the input to the modulator 4, and automatically transmits a message when it is determined that the communication area is available as described later. A control signal is supplied to the modulator 4 to call the playback dial.

FIG. 2 shows an operation flowchart of the car telephone of this embodiment.

First, in step 10, when the power of the telephone device is turned on, it is first determined in step 11 whether or not a radio wave having a strength sufficient for the device to reach whether it is within the communication range or outside the communication range has arrived. This can be determined by inputting to the control unit 9 the signal received by the antenna 8 is amplified by the high frequency unit 7 and demodulated by the demodulator 5. If it is determined that the call is out of the service area, the determination is repeated until the call is available. Now, when the two conditions of power-on and being within the communication range are met, next, at step 12, the control unit 9 automatically calls the message reproduction dial. If there is a message at the called up base station, the fact is notified by a DTMF tone. Therefore, this is amplified by the high frequency unit 7, demodulated by the demodulator 5 and
By decoding with the receiver 6, the presence or absence of a message can be known through the control unit 9. If it is determined in step 13 for making this determination that there is no message, the process directly proceeds to step 14 to end the call.

On the other hand, if it is determined in step 13 that there is a message, then the process moves to step 15 and the control section 9 causes the timer to start. Step 1 at the same time
At 6, an alarm sound is generated from the control unit 9 through the demodulator 5 and the speaker 2 to notify the caller that there is a message. Then, if the caller picks up the handset while the alarm sound is being generated or if the caller is hands-free, the call button on the operation key 3 is pressed to determine off-hook in step 17. When the control section 9 determines off hook, the alarm sound is turned off in step 18, and the message from the message reproduction dial is reproduced in step 19. When the reproduction of the message is completed, the caller manually operates to move to step 20 and end the call.

On the other hand, if the timer does not go off-hook during the operation period of the timer started at step 15, it is judged at step 21 that the timer is over, and if it is before the time, the procedure returns to step 17 to wait for the off-hook, but the time is over. If this happens, it is determined that the caller cannot pick up the call, the alarm sound is turned off in step 22, and the call is automatically terminated in step 23.

Through the above-described operation, the telephone device automatically determines whether the callable area is inside or outside after the power is turned on, and when it is in the callable area or enters the callable area, the base station is automatically set. Call the message playback dial to determine if there is a message, and if there is a message, inform the caller of the presence of a message with an alarm sound, so you can reliably receive the message without any special operation. ..

In the above embodiment, the case where the presence / absence of a message is judged by the DTMF tone when the message reproduction dial is called is shown as an example.
It works effectively when the base station has the function to notify by F tone, for example, "I have one message now" or "I do not have any message for you now." In a system in which the presence / absence of a message is notified by a voice message such as "," it is necessary to incorporate a voice recognition program in the control unit 9. However, even with such a configuration, the presence / absence of a message can be determined. Further, in the above-described embodiment, the configuration in which the presence or absence of a message is notified by the alarm sound is illustrated, but a system of notifying a caller by blinking or vibration of a lamp can of course achieve the intended purpose.

In the above embodiment, a car telephone or a mobile telephone has been described as an example of the telephone device, but the present invention is also applicable to other telephone systems, such as a local wireless telephone system and an electronic mail system.

[0020]

As described above, the telephone device of the present invention automatically makes a call to the message reproduction dial of the base station when the telephone is ready for communication, such as when the power is turned on or when the telephone communication area is reached. Since it is configured to check whether there is a message and notify the caller of the message if there is a message, the caller does not even have to be aware of whether the phone has entered the coverage area or not. Since it is possible to automatically know whether there is a message registered in the message playback dial without calling to the message playback dial, the convenience of being able to reliably receive the message, as well as that of car phones, etc. In this case, you can concentrate on driving, which has the effect of increasing safety.
