2. Description of the Related Art In recent years, there has been proposed a caller ID function service capable of recognizing a telephone number of a call destination at the time of an incoming call. Such a caller ID function service aims at protecting privacy. A function to prevent the other party (destination) from sending out the telephone number of the user (destination) based on a user's operation at the time of dialing, and a function to prevent a mischievous call from being made when a call is received. If you don't recognize your phone number,
That is, when the destination is set not to transmit the telephone number of the destination at the time of dialing, a function of transmitting a signal or a message notifying the destination that the reception has been rejected is provided while rejecting the incoming call. Such a function is realized in a communication device of a destination or a destination, or in an exchange connecting the destination and the destination.

[0003]

By the way, in a communication device which can use the above-mentioned caller ID function service, it is necessary to recognize the telephone number of the destination when receiving an incoming call or to notify the telephone number of the user (the destination). Caller, or automatically reject incoming calls when the incoming caller's phone number cannot be recognized. However, the other party can be called without notifying the user (destination) phone number. When a call is made to make a call and the other party (destination) is set to automatically reject the call when the destination phone number cannot be recognized, the user (destination) Sends a predetermined signal to the exchange by performing a predetermined operation in response to a signal or message indicating a call rejection sent from the other party (destination) or the exchange. Therefore, it is necessary to make a dial call without activating the function of once terminating the communication with the exchange and hiding the user's telephone number, which requires complicated operations by the user to communicate with the other party. There was a problem.

[0004] It is an object of the present invention to provide a communication device that can reliably call a partner device without requiring a complicated operation by a user.

[0005]

In order to achieve the above object, according to the first aspect of the present invention, an incoming call is set so as to reject an incoming call if caller information is not attached at the time of dialing in the other party's device. In a communication device using a communication system in which a signal or message for rejecting an incoming call is sent from a partner device or an exchange, a call rejection signal or a call rejection message sent from the partner device or an exchange is detected. And a control means for permitting the attachment of the caller information to the other party device when an incoming call rejection signal or an incoming call rejection message is detected by the detecting means.

According to a second aspect of the present invention, when an incoming call is set so as to reject an incoming call if no caller information is attached at the time of dialing in the other party's device, the incoming call is rejected from the other party's device or the exchange. In a communication apparatus using a communication system in which a signal or a message to be transmitted is sent, a storage means for storing the other party number used at the time of dialing, a call rejection signal or a call rejection sent from the other party apparatus or exchange. Detecting means for detecting a message, and, when an incoming call rejection signal or an incoming call rejection message is detected by the detecting means, once release the connection with the exchange, and make a dial call based on the other party number stored in the storage means.

Reference numeral 11 denotes an input discriminating unit 11-1 for discriminating the type of operation signal issued from the function button 8, a dial unit 11-2 for transmitting a signal such as DTMF to the communication line 1 through the speech circuit 4, and a speech circuit. 4 is a control circuit including an input signal determining unit 11-3 for determining a tone signal or a message signal coming from the communication line 1 input via the control unit 4, and a control unit 11-4 for controlling operation of each unit.

First, an example of the operation of the communication device configured as described above when dialing out will be described with reference to the flowchart shown in FIG.

The user picks up the handset 5 from the apparatus main body (step F1), or the on-hook key of the function button 8 is operated, and the operation of the on-hook key is determined by the input determining unit 11-1 and the control unit 11- 4 (step F2), the control unit 11-4 controls the hook switch 3 to close the communication line 1 (step F3), and establishes connection with the exchange.

After the connection with the exchange is made,
The user operates the function button 8 to input the other party's number. The input of the other party's number by the function button 8 is determined by the input determination unit 11-1 and the control unit 11
-4 (step F4), the controller 11-4
Stores the other party number determined by the input determination unit 11-1 in the RAM 9 (step F5), and
Based on the registration status of various settings stored in the AM 9, it is determined whether attachment of caller information (caller ID) is necessary or unnecessary (step F6).

The necessity of attaching the cola ID is determined by the input discriminating unit 8 confirming the necessity of attaching the cola ID based on the operation of the function button 8 by the user, and storing the result in the RAM 9. , Is set in advance before dialing.

When the control unit 11-4 determines that it is necessary to attach a caller ID at the time of dialing (step F6), the control unit 11-4 sends the dial unit 1 a.
The caller ID and the destination number transmitted from the input discriminating unit 11-1 are transmitted to 1-2, and the dial unit 11-2 transmits a DTMF signal based on the destination number and a caller attached before the DTMF signal. Dial transmission is performed by transmitting the ID and the communication circuit 4 to the communication line 1 (step F7).

On the other hand, if the control section 11-4 determines that it is not necessary to attach a caller ID when dialing out (step F6), the control section 11-4 sends the dial section 1 a call.
1-2 is notified of the other party number transmitted from the input discriminating unit 11-1, and the dial unit 11-2 transmits a DTMF signal based on the other party number from the communication circuit 4 to the communication line 1 to dial. A call is made (step F8).

Then, when a connection with the exchange is made based on the dial call, the incoming call is rejected if the caller ID is not attached at the time of the dial call in the partner device based on the dial call. If it is determined that an incoming call has been set, a signal or message indicating that the incoming call has been rejected is sent from the exchange.

The signal or message indicating the rejection of the call transmitted from the exchange is output from the receiver or the speaker 7 of the handset 5 through the communication circuit 4, and is also input to the input signal discriminator 11-3. When the signal discriminating unit 11-3 discriminates the signal or the message indicating the rejection of the incoming call and transmits it to the control unit 11-4 (step F9), the control unit 11-4 controls the display circuit 10 to change the caller ID. A display is provided to inform the user that the incoming call has been rejected because no attachment has been made (step F1).
0) together with a predetermined signal (tone) from the dial unit 11-2 through the communication circuit 4 by controlling the dial unit 11-2.
Is transmitted to the exchange, or the caller ID and the caller ID stored in the RAM 9 are transmitted from the dial section 11-2 to the exchange through the communication circuit 4, whereby the caller ID is attached by the service of the exchange (step F11). Thus, a call is made in the partner device, and when the partner device responds to the call (step F12), communication with the partner device is performed (step F13).

It should be noted that dialing is performed with a caller ID attached (steps F1 to F7), and dialing is performed without a caller ID attached (steps F1 to F7).
In F6 and F8), if the other party device based on the dialing is set to receive a call even if no caller ID is attached at the time of dialing, a signal indicating call rejection is received from the exchange. A call is made in the partner device without sending a message or message, and when the partner device responds to the call (step F12), communication with the partner device is performed (step F13).

Therefore, according to the above operation control, the caller I
Even if the dialing is performed without attaching D, even if the incoming call is set so as to reject the incoming call if the caller ID is not attached at the time of dialing in the destination device based on the dialing, it is used. It is possible to reliably call the other device without requiring complicated operation by the user.

Next, another example of the operation at the time of dial transmission will be described with reference to the flowchart shown in FIG. Note that the dial transmission operation is the same as the dial transmission operation (steps F1 to F10 in FIG. 2) in the above-described example of the dial transmission operation, and a description thereof will be omitted.

When dialing is performed without attaching a caller ID (steps F1 to F6 and F8), a signal or message indicating that the incoming call has been rejected is sent from the exchange, and the input signal discriminating section 11-3 Is determined to be a signal or a message indicating call rejection, and the control unit 11-
4 (step F9), the control unit 11-4 controls the display circuit 10 to display a message to inform the user that the incoming call was rejected because the caller ID was not attached (step F10). ), And controls the hook switch 3 to release the communication line 1 (step F21).

When a predetermined time has elapsed after the communication line 1 was opened (step F22), the control unit 11-
4 controls the hook switch 3 to close the communication line 1 (step F23), establishes connection with the exchange, and notifies the dialer 11-2 of the caller ID and the other party number stored in the RAM 9; The dial unit 11-2 performs dial transmission by transmitting a DTMF signal based on the other party number and a caller ID attached before the DTMF signal from the communication circuit 4 to the communication line 1 (step F2).
4).

When dialing is performed with the caller ID attached as described above (steps F23 to F24).
Even if an incoming call is set to reject an incoming call when a caller ID is not attached to the other device based on the dial call when the caller ID is not attached, a signal or message indicating the rejection of the call is transmitted from the exchange. Without being called, a call is made in the partner device, and when the partner device responds to the call (step F25), communication with the partner device is performed (step F26).

Therefore, according to the above operation control, the caller I
Even if the dialing is performed without attaching D, even if the incoming call is set so as to reject the incoming call if the caller ID is not attached at the time of dialing in the destination device based on the dialing, it is used. It is possible to reliably call the other device without requiring complicated operation by the user.

Finally, still another example of the operation at the time of dialing will be described with reference to the flowchart shown in FIG.
Note that the dial transmission operation is the same as the dial transmission operation (steps F1 to F10 in FIG. 2) in the above-described example of the dial transmission operation, and a description thereof will be omitted.

When dialing is performed without attaching a caller ID (steps F1 to F6 and F8), a signal or a message indicating that the incoming call has been rejected is sent from the exchange, and the input signal discriminating section 11-3. Is determined to be a signal or a message indicating call rejection, and the control unit 11-
4 (step F9), the control unit 11-4 controls the display circuit 10 to notify that the incoming call was rejected because the caller ID was not attached, and to determine whether the caller ID may be attached. (Step F1)
0).

Then, the function button 8 is operated by the user to make an input requesting the attachment of the cola ID, and the input requesting the attachment of the cola ID by the function button 8 is judged by the input judgment section 11-1. Control unit 11-
4 (step F31), the controller 11-4
Controls the dial unit 11-2 to cause the dial unit 11-2 to transmit a predetermined signal (tone) to the exchange through the communication circuit 4, or to transmit the other party number and the caller ID stored in the RAM 9 to the dial unit 11-. 2 to the exchange via the communication circuit 4 so that the caller ID is attached by the service of the exchange (step F32), so that a call is made in the other party's device, and when the other party answers the call. (Step F33), communication with the partner device is performed (Step F34).

On the other hand, the function button 8 is operated by the user to make an input for rejecting the attachment of the cola ID, and the input for rejecting the attachment of the cola ID by the function button 8 is determined by the input determining unit 11-1. Controller 11-4
(Step F31), the control unit 11
-4 controls the hook switch 3 to release the communication line 1 (step F35), thereby ending the operation at the time of dialing.

Therefore, according to the above operation control, the caller I
Even if the dialing is performed without attaching D, even if the incoming call is set so as to reject the incoming call if the caller ID is not attached at the time of dialing in the destination device based on the dialing, it is used. It is possible to ensure that a call is made in the other party's device by a simple operation by a user, and to interrupt dialing for the purpose of privacy protection.

When the user operates the function button 8 to input the request for attaching the cola ID, the operation for calling the partner device is as follows. Is performed (steps F21 to F26 in FIG. 3).
You may do it.
