Abstract

PROBLEM TO BE SOLVED: To effectively use a caller's number informing service by call- originating caller's number information when the number of the opposite party designated upon calling is not stored. SOLUTION: A system control part 2 monitors which method is used for inputting a destination, i.e., direct input by ten keys, shortened dialing and one-operation dialing and when the destination is inputted by a registered dial, the part 2 checks the value of a caller's number non-informing flag Fh corresponding to a shortened number or a one-operation key number in a registered dial registering table. Then, when the value of the flag Fh is 0, a caller's number informing procedure is executed and when the value of the flag Fh is 1, a caller's number non-informing procedure is executed. When a terminal attribute is digital in the manual dialing with ten keys, the caller's number informing procedure is executed. Caller's number information is call-originated based on a caller's number informing service to be executed by a public network upon calling to an opposite party who is not stored.

Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to PSTN and ISD
The present invention relates to a communication terminal device such as a facsimile device that performs communication via a public network such as N.

[0002]

2. Description of the Related Art In ISDN, a service of notifying a called party of a caller ID has been available free of charge from the beginning. In recent years, the PSTN has also provided a service for notifying the called party of the caller ID to the called party for a fee, which is called a number display service.

[0003] The caller ID notification service is useful for preventing unwanted calls and mischievous calls because it can identify the caller without answering the incoming call. There is a problem in terms of privacy protection, since one's phone number can be unintentionally disclosed.

[0004] Whether or not a caller's number is notified to the called side using the caller ID notification service depends on the line contract form and dial form of the caller.

[0005] Specifically, taking the number display service in PSTN as an example, suppose that the calling side has a line contract with a PSTN carrier in the setting of "not notify every line", and the calling side has contracted. For all calls / communications originating from an existing line, if dialing is performed as usual, the caller ID is not notified to the called party. However,
Even in the case of "Hide each line", when dialing, dial the special number "186" indicating that the caller ID is to be notified before the telephone number of the called party and dial the called party number. Is done.

On the other hand, assuming that the calling side has a line contract with a PSTN communication carrier with the setting of "notify every call",
For all calls / communications originating from the line to which the calling party has subscribed, if dialing is performed as usual, the calling party number is not notified to the called party. However, even in the case of “not notify every call”, when dialing, if a special number “184” indicating that the caller ID is not to be notified is dialed in front of the telephone number of the called party, the caller ID will be changed to the called party. Not notified.

[0007] In this way, the calling side informs the called side that it is about to make a call by using the caller ID notification service, or notifies his / her own telephone number. Judgment of the caller who does not want to be made is made, furthermore, the actual contract status regarding the transmission number notification of the line to which the user is subscribed is judged, and the telephone number of the called party is dialed as it is, or
It is necessary to determine whether to dial with a special number such as "86" or "184".

[0008]

For this reason, it is complicated for the calling party to make a decision regarding the caller ID notification service when calling the called party, and the notification is made by erroneous judgment or erroneous operation. If you do not want to be notified, your phone number will be notified to the called party, or conversely, if you want to be notified, your phone number will not be notified to the called party, so the caller ID notification service will be activated There was a problem that it could not be used.

The present invention has been made in view of the above circumstances, and it is necessary for the user on the calling side to be aware of the form of the line contract regarding the caller ID notification service and the form of designating notification / non-notification of the calling telephone number. It is another object of the present invention to provide a communication terminal device capable of effectively using the caller ID notification service.

Further, the facsimile apparatus 1 performs a call communication using the telephone 13 via the B channel set by the D channel control unit 9.

The facsimile apparatus 1 has a dial register shown in FIG. 3 for a speed dial function and a one-touch dial function, which are registration dial functions that can save the trouble of inputting a destination, rather than directly inputting a destination number. The table 4a is stored in the RAM 4 in advance.

In FIG. 3, the registration dial registration table 4a is configured as a table in which the partial registration tables of the abbreviated dial registration table and the one-touch dial registration table are combined. Each record specified by the registration number of each partial registration table is composed of a destination number field, a destination name field, and a calling number non-notification flag Fh.

The abbreviated dial registration table is composed of 100 records corresponding to the registration numbers "00" to "99". Each registration number (abbreviated number) has a destination number, a destination name, and a call origination number. The number non-notification flag Fh is registered in association with the number. The registration of the destination number and the destination name is performed interactively using the display 7j as in the conventional case. That is, registration is performed by designating the abbreviated number to be registered, inputting the destination number, and inputting the destination name. Also, the transmission number non-notification flag Fh specifies the abbreviated number to be registered, inputs the destination number, inputs the destination name, and then notifies the transmission number for the destination of the destination number or Let me choose whether or not to notify,
When “non-notification” is selected, the value of the corresponding calling number non-notification flag Fh is set to 1, and when “notification” is selected, the value of the corresponding calling number non-notification flag Fh is set. Registered by setting to 0.

Next, the procedure of the transmission process in the facsimile machine 1 will be described with reference to FIG.

In the figure, the system control unit 2 determines whether the destination is to be directly input using the numeric keypad 7a, abbreviated dialing,
Alternatively, it is monitored whether the operation is performed by one-touch dialing (No loop of judgment 101), and when an address is input (Yes of judgment 101), the address input is performed by a speed dial or a one-touch dial registration dial. It is determined whether or not it is true.

When the destination is entered by the registration dial (Yes in decision 102), the value of the transmission number non-notification flag Fh corresponding to the abbreviated number or the one-touch key number in the registration dial registration table 4a is checked ( Process 103).

If the value of the flag Fh is 0 (Yes in the decision 104), the calling number notification procedure is executed (Process 105), and if the value of the flag Fh is 1 (No in the decision 104). Then, a calling number non-notifying procedure is executed (process 108).

If it is determined in step 102 that the call is not a registered dial, that is, if it is a manual dial using the numeric keypad 7a (Yes in step 102), it is determined whether the terminal attribute of the call is digital (G4FAX). Judgment is made (Judgment 106), and if the terminal attribute is digital (Yes in Judgment 106), a calling number notification procedure is executed (Process 105).

If the terminal attribute is not digital, G3FA
X or analog of telephone call (decision 10
No. 6), it is further determined whether or not the calling mode is G3 FAX (decision 107). If the calling mode is G3 FAX (Yes in decision 107), a calling number notification procedure is executed (step 107). Process 105).

If the calling mode is not the G3 FAX but the normal call mode by the telephone set 13 or the on-hook dial mode by pressing the on-hook key 7i (No in decision 107), the calling number non-notification procedure is executed. (Process 108).

According to the transmission processing procedure shown in FIG.
When the destination is input by the registration dial, the transmission number notification or non-notification procedure is executed according to the value of the transmission number non-notification flag Fh corresponding to the input destination in the registration dial registration table 4a. For each destination registered in the registration dial registration table 4a, notification / non-notification of the calling number can be arbitrarily set.

When the destination is input by manual dialing, the calling number notification procedure is executed only when the terminal attribute is digital. When the terminal attribute is not digital, the calling mode is set to G3.
When it is a fax, a calling number notification procedure is executed,
When the calling mode is not G3 FAX, the calling number non-notifying procedure is executed. The priority in determining whether to execute the calling number notifying process or the non-notifying process depends on whether the destination is input by the registration dial or not. The priority order setting function may be started by a combination operation of pressing the [Function] key 7f and entering a number using the numeric keypad 7a, not limited to the order of the terminal attribute and the calling mode.
You may make it possible to set the order desired by the user.
Further, whether to perform the calling number notification processing or the non-notification processing is determined based on whether or not the destination is input by the registration dial, the terminal attribute, or only one of the calling modes, or only two. The combination of the two determinations selected from the three types of determination in the case of only two determinations can be arbitrarily selected, and the [Function] key 7f is pressed and the number by the numeric keypad 7a is selected. The determination selection function may be activated by an input combination operation, so that the user can select a desired determination and set the priority of the selected determination. Further, using the registration dial registration table 4a, which is originally for one-touch dialing and speed dialing, each one-touch key number,
The destination number corresponding to the abbreviated number is registered in association with the calling number non-notification flag Fh, and the calling number notification procedure is executed when the destination number with the value of the calling number non-notification flag Fh of 0 is specified. Rather than registering, the destination number for which the calling number should not be notified is registered in the dedicated non-notifying destination table, and the destination number entered at the time of calling is not registered in the non-notifying destination table Only the caller ID notification procedure is performed, or the callee number to be notified of the caller ID is registered in a dedicated callee address table, and the destination number entered at the time of calling is registered in the callee address table. The calling number notification procedure may be performed only when the destination number has been registered. In such a case, if the destination number is entered by registered dial such as speed dial or one-touch dialing Not only, even if the destination number by the ten key 7a is input by manual dialing, for each destination number entered, the caller ID /
Non-notification can be set arbitrarily.

Here, the calling number notifying procedure of the process 105 and the calling number non-notifying procedure of the process 108 will be described.

In the number display service provided on the PSTN line, a service is provided by adding "184" and "186" in front of the other party's telephone number so as to control whether or not the calling number can be notified.

Specifically, the calling side sets "notify every line"
Assuming that you have a line contract with a PSTN carrier in the above settings, for all calls and communications originating from the line to which the calling party has subscribed, if you dial as usual, the caller ID will be sent to the called party. Although not notified, even in the case of "not notify for each line", when dialing, if a special number "186" indicating that the caller ID is to be notified is dialed before the telephone number of the called party, the caller ID will be changed. The called party is notified.

Further, if the calling side has a line contract with a PSTN communication carrier in the setting of “notify every call”,
For all calls and communications originating from the line to which the calling party has subscribed, the caller ID will not be notified to the called party if dialing as usual, but even if `` Hide each call, '' If a special number "184" indicating that the caller number is not to be notified is dialed in front of the telephone number of the called side, the caller number is not notified to the called side.

Therefore, if the calling party has a line contract with the setting of "not notify every line", dial "186" before the input destination number and dial "105". The number notification procedure can be realized, and if the input destination number is dialed as it is, the calling number non-notification procedure of the process 108 can be realized.

If the calling party has a line contract with the setting of "not notify every call", dialing the input destination number as it is can realize the calling number notification procedure of processing 105, and the input destination number If dialing is performed with the number “184” added before “”, the calling number non-notifying procedure of the process 108 can be realized.

In the case of ISDN, the notification / non-notification of the calling number can be controlled by “184” and “186” in the ins net 64 in the same manner as in the PSTN. The non-notification procedure can be realized, but it can also be realized by instructing display permission / display prohibition in the calling number information element of the call setup message SETUP. This method uses “184” and “1”.
Since the priority is higher than the dialing of "86" and the contract status of the line, it is possible to realize the calling number notification / non-notification procedure without depending on the network function and the contract status.

In the above-described embodiment, the present invention is applied to a facsimile apparatus which is one of the communication terminal apparatuses.
Any communication terminal device that is connected to a line that can control non-notification or has a function of controlling notification / non-notification of a calling number when making a call can be similarly applied.
