Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a terminal device for automatically calling a destination connected to a public telephone line network,
In particular, the present invention relates to a terminal device that automatically makes a call to a partner who needs to send an additional number together with a normal number.

[0002]

2. Description of the Related Art In dormitories and small companies, an additional number type dial-in system is often used, in which an additional number is sent after the other party's telephone number to connect directly to multiple people. There is. In addition, as information terminal devices such as facsimile machines become widely used in general households,
Many information services of the type in which a representative is called once and then the desired information is entered by entering a box number are being provided.

When the terminal device automatically makes a call to the other party adopting such an additional number type dial-in system or the information service provider who needs to input the box number, the other party Some kind of voice message often flows. For example, when using an information service, a voice message such as "Please input the box number of necessary information." Will be heard when the representative is called. Therefore, it is necessary to send an additional number such as a box number after an appropriate interval after the normal number corresponding to the telephone number of the other party.

Conventionally, the pause code corresponding to this interval is registered in advance, that is, when the dial number (normal number and additional number) of the other party is registered in the one-touch dial key or the like, this pause is performed. This was handled by registering the code as well.

[0005]

However, the contents of the voice message sent from the other party may change on a weekly or monthly basis by changing the number of box numbers handled.

Therefore, the length of the voice message may be longer than the length of the pause code registered at the beginning, and in this case, the additional number is transmitted while the voice message is flowing. , The false detection of the additional number is likely to occur. Further, depending on the other party, there is a case where the additional number is not detected during the transmission of this voice message, and in this case, there is a problem that the connection cannot be established to the other party.

It is an object of the present invention to provide a terminal device capable of automatically calling a partner who needs to send an additional number together with a normal number without paying attention to the timing of sending the additional number. And

[0008]

In order to achieve the above object, the present invention provides a network control unit for connecting to a public telephone line network, and a silent state detecting unit for detecting a silent state of the public telephone line network. , A storage means for storing the dialed number of the other party as an ordinary number and an additional number, and after reading the ordinary number from this memory means to call the other party, the silent state is continuously detected for a predetermined time by the silent state detection section. It is intended to provide a terminal device capable of automatically calling, which is provided with a control means for detecting whether or not to carry out, and controlling so as to send out the additional number stored in the storage means when it continues for a predetermined time.

Further, when a predetermined time has elapsed after reading the normal number and calling the other party, the additional number may be forcibly transmitted regardless of whether or not the silent state is detected.

[0010]

According to the present invention, of the dial numbers stored by distinguishing between the ordinary number and the additional number, the ordinary number is read out first to call the other party connected to the public telephone line network, and thereafter, It is detected whether the public telephone line network is in a silent state for a predetermined time continuously. Then, when a silent state is detected for a predetermined period of time, an additional number is sent to automatically call the other party.

Further, if the silent state is not detected within a predetermined time after the normal number is read and the other party is called, the additional number is compulsorily transmitted, whereby the public telephone line network Enable automatic calling even when there is a large amount of noise.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Embodiments of the present invention will be specifically described below with reference to the accompanying drawings. FIG. 1 is a block diagram showing the configuration of a terminal device used in this embodiment.

In this terminal device, the control unit 1 performs control processing of each unit of the device, and the system memory 2
Stores various data necessary for a control program executed by the control unit 1 and forms a work area of the control unit 1.

The parameter memory 3 stores various information unique to the device. The operation unit 4 provides an interface for an operator to operate this terminal device, and includes function keys for making various settings for the device, one-touch dial keys for calling the dial number of the other party with one touch, etc. It is equipped with various operation keys.

The DTMF signal generator 5 is for producing a DTMF signal to be sent to the public telephone line network, and the silent state detector 6 detects the energy level of the sound in the public telephone line network, and this energy level. It is to judge whether or not there is a silent state by whether or not is less than or equal to a predetermined value. The network control unit 7 is for connecting the terminal device to a public telephone line network.

Then, each of these components exchanges data with each other via the system bus 8.

FIG. 2 is a flow chart showing the operation when the terminal device of FIG. 1 automatically makes a call to a destination that needs to send the additional number together with the normal number.

First, by using the operation unit 4, the dial number of the other party who makes the automatic call is distinguished and registered as a normal number and an additional number. At the same time, register in advance how long after the normal number is sent, the additional number is sent when a continuous silence state is detected, and for how long this detection is continued when this continuous silence state cannot be detected. deep.

In this state, when a specific one-touch dial key of the operation unit 4 is pressed to request automatic calling to a destination registered in advance, first, the relay of the network control unit 7 is controlled. A DC loop is formed (S201). Then, using the DTMF signal generator 5 and the network controller 7, the ordinary number is sent to the public telephone line network to call the other party (S202). After that, when all the normal numbers have been transmitted, the silent state detection unit 6 starts detecting the silent state (S203). Then, the silent detection limit timer for measuring the detection time limit is started, and the continuous silence detection timer for measuring the continuous silent state period is initialized to 0 (S204).

Here, when the silent state detecting section 6 detects a silent state, the continuous silence detection timer is counted (S206) and it is checked whether or not the continuous silence detection timer exceeds a predetermined value (S206). S207). If it does not exceed the predetermined value, the process returns to S205 to determine again whether or not the silent state is detected. On the other hand, if it exceeds the predetermined value, the silent state detection unit 6 stops detecting the silent state (S208), and the additional number is sent out via the DTMF signal generation unit 5 and the network control unit 7 (S209).

On the other hand, when the silent state is not detected by the silent state detecting section 6 (S205), the continuous silence detecting timer is reset (S210), and then the silent detection limit timer is checked to see if it exceeds a predetermined value. I will check. Then, if it does not exceed the predetermined value, the process returns to S205 to determine again whether or not the silent state is detected. On the other hand, if it exceeds the predetermined value, the silent state detection unit 6 stops detecting the silent state (S208), and the additional number is set to DTM.
It is sent out through the F signal generator 5 and the network controller 7 (S2
09).

It should be noted that, for a predetermined time during which the silent state continues,
Regarding the predetermined time for which the silent state is continuously detected, the setting may be appropriately changed according to the situation such as noise of the public telephone line network or the length of the voice message sent from the other party.

[0023]

As described above, the continuous silent state after the sending of the normal number is detected, and it is determined that the voice message or the like is not flowing from the other party because the silent state continues for a certain period. The additional number can be sent at an appropriate and accurate timing, and it is possible to flexibly deal with various voice messages sent from the other party.

Further, even if no continuous silent state is detected for a predetermined period, the silent state is terminated within a predetermined time limit and the additional number is sent to the other party. Even if the silent state is not detected due to noise or noise around the calling side, the additional number can be effectively transmitted.
