Abstract

PURPOSE:To evade a sense of displeasure to a replied party by providing a message sending means sending a voice message of apology, and disconnecting a telephone line if a call reaches a general subscriber erroneously in automatic dialing. CONSTITUTION:If a wrong telephone number is sent to a telephone network 50 and reaches a general terminal equipment 60 because of misregistration of the telephone number or the effect of noise on a telephone line or the like, no carrier signal is sent even if the subscriber replies the call. Thus, a MODEM 30 cannot detect the carrier signal within a prescribed time and sends a communication error signal to a communication terminal equipment 70. The communication terminal equipment 70 uses a voice message generating means to allow a voice generator 74 to produce a preset apology message and it is sent to a telephone line so as to allow the subscriber of the general terminal equipment 60 to receive the message as a voice. Then after the end of transmission of the apology message, the telephone line is disconnected.

Description

[Detailed description of the invention] [Industrial application field] The present invention relates to an automatic calling method for a communication terminal device.

[Conventional technology]

The conventional automatic calling system of a communication terminal device will be explained using the block diagram of FIG. 4 and the situation diagram of FIG. 5 showing the communication situation between the communication terminal device IO and the communication terminal device 20.

Communication terminal device 10 on the sending side and communication terminal device 20 on the receiving side
is connected to the telephone network 50 via modems 30 and 40. The telephone network 50 also includes general subscriber terminal devices (
60 (hereinafter referred to as a general terminal device) is also connected.

The communication terminal device IO has an input/output device 11 such as an optical reader, a keyboard, a printing device, etc., a storage device 12 such as a semiconductor memory or a magnetic storage device, and a C which connects these and controls them.
It is composed of PU13. The CPU 13 has an automatic calling means, an automatic receiving means, a communication state determining means, and a data transmitting/receiving means based on the programs and data stored in the storage device 13. The communication terminal device 20 is the same device as the communication terminal device 10, and the input/output device 21, storage device 22, and CPU 23 that constitute it have the same two functional means as the communication terminal device 10. .

The communication terminal device 10 automatically calls a pre-registered communication terminal device 20 via the telephone network 50 using an automatic calling means. After the communication terminal device 20 on the receiving side performs a response operation to the telephone network 50 by the automatic call receiving means, the communication terminal device 20 on the receiving side responds to the telephone network 50 by using the modem 3 connected to the communication terminal device 10 on the calling side.
A carrier signal is sent to 0. When the modem 30 detects the carrier signal, it sends a signal indicating that the carrier signal has been detected (hereinafter referred to as a normal communication signal) to the communication terminal device 10.
Send to. When the communication terminal device IO receives the communication normal signal, the communication enable determining means determines that the communication terminal device 20 responds and becomes communicable, and the data transmitting/receiving means starts transmitting and receiving subsequent information. The data transmitting/receiving means disconnects the telephone line when data transmission and reception are completed.

Further, when the communication terminal device IO automatically makes a call and the modem 30 cannot detect a carrier signal within a certain period of time, the modem 30 detects a carrier signal and when the IO receives a communication abnormality signal, the communication possibility determining means determines whether the communication is possible. It was determined that there was an abnormality and the telephone line was disconnected.

[Problem to be solved by the invention]

The above-mentioned automatic calling method of the conventional communication terminal device is such that when a call is mistakenly received at the general terminal device 6o of a general subscriber, the modem 30 connected to the communication terminal device 1O cannot detect the carrier from the other party. Since the communication terminal device 10 immediately disconnects the line, there is a problem in that the other party who responds using the general terminal device 60 feels uncomfortable.

SUMMARY OF THE INVENTION An object of the present invention is to provide an automatic dialing system for a communication terminal device that can disconnect the telephone line without causing discomfort to the other party even if a call is mistakenly received by a general subscriber during automatic dialing by the communication terminal device. It is in.

[Means to solve the problem]

An automatic calling method for a communication terminal device of the present invention is an automatic calling method for a communication terminal device that is connected to a telephone network via a modem and has an automatic calling means and an automatic receiving means, in which the communication terminal device uses the automatic calling means to If the modem connected to the communication terminal device when making an automatic call cannot receive a carrier signal indicating a response from the other party's communication terminal device within a certain period of time, the modem connected to the communication terminal device can be set in advance by the communication terminal device on the calling side. The telephone line has means for disconnecting the telephone line after transmitting the voice message being sent to the telephone line.

〔Example〕

Next, the present invention will be explained with reference to the drawings.

FIG. 1 is a block diagram of one embodiment of the present invention.

This embodiment has a configuration in which the communication terminal device (2) 0 on the transmitting side in the conventional configuration shown in FIG. 4 is changed to a communication terminal device 70.

The communication terminal device 70 is composed of an input/output device 71, a storage device 72, a voice generating device 74, and a CPU 73 that is connected to and controls these devices. The sound generation method of the sound generation device 74 can be a recording method or a synthesis method, and these methods are executed.

FIG. 2 is a flowchart of the internal processing of the communication terminal device 70 in the same embodiment, and FIG. 3 is a situation diagram showing the communication status between the communication terminal device 70 and the general terminal device 60 shown in FIG.

The communication terminal device 70 on the calling side performs a calling operation using the automatic calling means (step SL), transmits the telephone number to the telephone network 50 via the modem 30, and after connecting the line, waits for a reply from the carrier signal. At this time, if an incorrect telephone number is sent to the telephone network 50 due to an error in registering the telephone number or the influence of noise on the telephone line, and the call is received at the general terminal device 60, even if the subscriber answers. No carrier signal is transmitted. Therefore, the modem 30 cannot detect the carrier signal within a certain period of time and transmits a communication abnormality signal to the communication terminal device 70. The communication terminal device 70 receives the signal and determines that there is a communication abnormality using the communication status determining means (step 2).
The voice message generation means generates a preset apology message in the voice generation device 74, and sends it to the telephone line so that the subscriber of the general terminal device 60 can receive it as voice (step 3). After sending the apology message, the telephone line is disconnected (step 4).

The telephone line is the correct party (in this case, the communication terminal device 20
), a carrier signal is transmitted, and if the modem 30 that received this carrier signal transmits a normal communication signal, data is transmitted and received by the data transmitting/receiving means (step 5), and when it is finished, the telephone line is is disconnected (step 6).

〔Effect of the invention〕

As explained above, in the present invention, when a call is mistakenly received by a general subscriber when a communication terminal device makes an automatic call, when the communication terminal device on the calling side recognizes that there is a communication abnormality, it sends out an apologetic voice message and calls the subscriber. By having a message sending means that disconnects the line, there is an effect that the person who responded does not feel uncomfortable.
