JPH04321351A - Misdialing recurrence preventing device - Google Patents

Abstract

PURPOSE:To prevent reocurrence of misdialing in a telephone set or a facsimile equipment or the like. CONSTITUTION:A dial number inputted from an input section 1 is stored in a dial number tentative storage section 2a. A mis-dial deciding section 2b decides whether or not a line is correctly connected to a prescribed opposite party. A retrieval section 7 decides whether or not a dial number stored in the dial number tentative storage section 2a is in existence in dial numbers whose communication has been successful. When the mis-dial discrimination section 2b discriminates it that the dial number is not connected to a prescribed opposite party, that is, in the case of mis-dialing and the retrieval section 7 decides it presence, then a radial start section 8 is started for the redialing. On the other hand, when the retrieval section 7 decides its absence, the operation is terminated.

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a device for preventing the recurrence of incorrect dials, and more particularly to a device for preventing the recurrence of incorrect dials that improves the accuracy of determining incorrect dials.

0002

2. Description of the Related Art Telephones, facsimile machines, etc. generally have a speed dial function. If you register an incorrect phone number when registering speed dial, the wrong party will be called every time you use the speed dial from now on.
This will cause trouble to the other person. Further, facsimile machines and the like have a re-dial function, and when the call cannot be sent to the called party, the facsimile machine re-calls a predetermined number of times at predetermined time intervals. At this time, if the telephone number of the called party is incorrect and the called party is using a telephone rather than a facsimile machine, the call cannot be sent and the call must be redialed many times. As a result, the other party receives many calls from the facsimile machine, causing a great deal of trouble.

[0003] In order to solve the above problems, various proposals have been made as follows.

(1) When the answer back tone is not returned after the line connection is completed, it is determined that the other party is not equipped with a facsimile machine, and the retransmission operation is not performed (Japanese Patent Application Laid-open No. 62 -217776).

(2) After calling the other party to whom the original is to be sent, if hook-off of the other party is detected within a predetermined time and an answer sound is detected within a certain time, processing for transmitting the original information is performed, and the other party is called. The retransmission process is executed only when the other party's hook-off is not detected within the specified time and the other party is busy. In other cases, it is assumed that there is some kind of abnormality and automatic retransmission is not performed. Showa 6
2-216474). (3) After making a call by redialing, if it is determined that a predetermined facsimile control signal does not arrive from the other party's terminal, the redialing operation is restored and subsequent redialing operations are canceled (Unexamined Japanese Patent Application Laid-Open No. 63-1998-
193667).

(4) Identifying whether or not a response signal from the other party to a call from a facsimile machine is a signal issued from the assumed terminal, and if the response signal is not issued from the assumed terminal, Stop retransmitting the outgoing signal (
JP-A-59-125171, JP-A-64-126
Publication No. 72).

(5) If a call to the same destination fails a predetermined number of times, re-dialing is prevented (Japanese Patent Laid-Open No. 63
-6662 publication).

[0008] According to the above-mentioned prior art, a party with an incorrect dialed number is not re-dialed, so there is an advantage that the other party is not inconvenienced, and a waste of time and money due to re-calling can be avoided. have.

[0009]

[Problems to be Solved by the Invention] However, in all of the above-mentioned prior art, it is determined that an incorrect dial has occurred due to failure of one call or a predetermined number of calls, and in order to prevent re-calling, for example, the other party's device doubles as a telephone. If someone accidentally answers the call using a facsimile machine or the like, there is a problem in that the caller will not be able to dial again even though the call was not made by mistake.

An object of the present invention is to eliminate the above-mentioned problems of the conventional device, and to redial even if the other party happens to answer using a telephone/facsimile machine or the like, without determining this as an incorrect dial. Accordingly, it is an object of the present invention to provide a device for preventing recurrence of incorrect dialing, which enables facsimile communication.

Another object of the present invention is to provide an apparatus for preventing the recurrence of erroneous dialing, which can more accurately recognize erroneous dialing.

0012

[Means for Solving the Problems] In order to achieve the above object, the present invention provides an input section for inputting a dial number of a communication partner, and a first dial number for storing the dial number input from the input section. a storage unit, an incorrect dialing determination unit that determines whether communication using the dialed number was successful, a second dialed number storage that stores dialed numbers with which communication was successful in the past, and the second dialed number. The present invention is characterized in that the storage section includes a search section for searching whether or not the dial number stored in the first dial number storage section is registered.

[0013]

According to the present invention, re-dialing is performed when the erroneous dial determination section determines that the dial is an erroneous dial, and the search section determines that the dial is registered. On the other hand, when the erroneous dial determination unit determines that the dial is an erroneous dial, and the search unit determines that the dial is not registered, the calling operation is stopped.

[0014] As a result, if a wrong dial happens to occur for some reason, facsimile communication can be completed successfully by dialing again. Furthermore, the accuracy of determining incorrect dialing can be improved.

[0015]

DESCRIPTION OF THE PREFERRED EMBODIMENTS The present invention will be described in detail below with reference to the drawings.

FIG. 3 shows a schematic block diagram of the hardware configuration when the present invention is applied to a facsimile machine. In the figure, 1 is an input unit corresponding to the keys on the panel of the facsimile machine, 2 is a control unit that controls the overall operation of the facsimile machine, 3 is a modem that modulates and demodulates image information to be sent and received, and 4 is a control unit of the facsimile machine. This is the network control unit (NCU). Further, 5 is an auto-dial unit that automatically dials the dial number input from the input unit 1;
7 is a dial number storage unit that stores telephone numbers from which facsimile communication was successfully performed in the past; 7 is a search unit that searches whether or not there is a dial number sent from the auto dial unit 5 in the dial number storage unit 6; 8 is a re-dial activation section.

The control unit 2 includes a storage unit that temporarily stores the dialed number input from the input unit 1, and a storage unit that temporarily stores the dialed number input from the input unit 1, and an error storage unit that determines whether or not the dialed number is an incorrect dialing based on the response of the other party to the dialing. It is equipped with a dial judgment function, etc.

Next, the configuration of this embodiment will be explained in more detail with reference to FIG. FIG. 1 shows a functional block diagram of an embodiment of the present invention. Note that the same reference numerals in FIG. 1 as in FIG. 3 indicate the same or equivalent components as in FIG. 3, and the description thereof will be omitted.

In the figure, 2a is a dial number temporary storage unit that stores the dial number entered from the input unit 1;
Reference numeral 2b indicates an incorrect dialing determination unit that determines whether the number dialed from the auto-dial unit 5 is a correct dial or an incorrect dialing; 2c indicates a facsimile communication determination unit that determines whether or not the facsimile communication is successful;
Reference numeral d designates an operation end control section that is activated when the erroneous dial determination section 2b determines that the dial is an erroneous dial, and the search section 7 determines that there is no dial. A switch 9 is turned on when the facsimile communication determining section 2c determines that the facsimile communication is successful and the searching section 7 determines that there is no dialed number.

The re-dial activation unit 8 is activated when the erroneous dial determination unit 2b determines that there is an erroneous dial and the search unit 7 determines that there is a dial.

Next, the operation of this embodiment will be explained with reference to the flowchart shown in FIG.

When a dial number is input from the input section 1 (step S1), the dial number is stored in the dial number temporary storage section 2a and automatically dialed by the auto dial section 5. The dial signal is sent to the line via the network control section 4.

Next, the incorrect dial determination unit 2b determines whether or not the dialed number is for a facsimile machine, based on the signals inputted through the network control unit 4 and the modem unit 3, that is, determines whether the dialed number is a correct dialed number or not. or whether it was a wrong dial (step S).
3).

[0024] For this determination, the technique disclosed in the above-mentioned prior art can be used. For example, as described in Prior Art (2) above, after a call is made to the other party to whom the document is to be sent, hook-off of the other party is detected within a predetermined time, and an answer tone from the facsimile machine is heard within a certain time. When the hook-off of the other party is detected, or if the other party's hook-off is not detected within a predetermined time and the other party is busy, it is determined that the dialed number is correct; in other cases, for example, after the hook-off, When there is a human voice response, or when there is no response at all, it can be determined that the dial was incorrectly dialed.

When the incorrect dial determination unit 2b determines that the dial is an incorrect dial, the search unit 7 determines whether the dial number stored in the dial number temporary storage unit 2a is stored in the dial number storage unit 6. (Step S4). Then, if there is a match (step S5
(Yes), since this is the number with which facsimile communication was previously possible, the re-dial activation section 8 is activated and re-dial is performed (step S6).

On the other hand, if step S5 is negative,
Since this is not the number used for facsimile communication in the past, the operation termination control section 2d is activated to open the line and terminate the facsimile communication operation.

[0027] When the step S3 is negative, that is,
When the wrong dial determination section 2b determines that there is no wrong dial, and the FAX communication determination section 2c determines that the facsimile communication was successful (step S7 is affirmative).
The search section 7 searches whether the dial number stored in the temporary dial number storage section 2a is stored in the dial number storage section 6 or not. Then, if the same number is not stored (step S8 is negative),
The switch 9 is turned on and the dial number is stored in the dial number storage section 6 (step S9).

On the other hand, even if step S3 is negative, if the facsimile communication is not successful (step S7 is negative), for example, when a busy tone is returned, the line is disconnected and the dial is re-dialed at an appropriate time thereafter. do. If step S8 is affirmative, the switch 9 is not turned on because the dial number with which the facsimile communication was successful has already been registered. Therefore, the dialed number is terminated without being re-registered.

As described above, according to this embodiment, even if an incorrect dial is determined, it is checked whether the dialed number has been successfully used for facsimile communication in the past, thereby preventing line confusion, etc. Even if a call happens to arrive at a different destination, it will not be determined that the wrong dial number has been entered. Therefore, incorrect dialing can be determined more accurately.

Although the above embodiment has been described using a facsimile machine, the present invention is not limited thereto, and can of course be applied to telephones and the like.

[0031]

As is clear from the above description, according to the present invention, even if it is determined that the dial is a mistake when dialing for the first time, it is not immediately determined that the dial is a mistake, and the dial number can be used for past facsimile communications. It checks whether the call was successful or not, and if it is successful, the call is re-dialed.

Therefore, even if the other party happens to answer the call using a telephone/facsimile machine or the like, the facsimile communication can be completed successfully by re-dialing rather than treating this as an erroneous dial. Furthermore, if a wrong dial is accidentally made for some reason, facsimile communication can be completed successfully by dialing again.

[0033] Furthermore, if the dialed number does not exist among the dialed numbers with which facsimile communications were successfully made in the past, there is a very high possibility that it is an incorrect dialing, and the accuracy of determining incorrect dialing can be improved.
