Abstract

The present invention receives a caller's telephone number provided by an ISDN at a fax receiver, receives fax data transmitted from a sender corresponding to the caller's telephone number, and determines whether the received fax data has been successfully received. Therefore, since a successful message is transmitted to the sender's fax in a predetermined message format, the sender's fax user can easily know whether or not the fax data is successfully received by the receiver's fax.

Description

How to send acknowledgment message using caller's phone number in general information communication network

The present invention relates to a method for transmitting an acknowledgment message. More particularly, the present invention relates to receiving a fax data by using a calling party number provided by an integrated services digital network (ISDN). The present invention relates to a method of transmitting an acknowledgment message using a caller's telephone number in an integrated information communication network (ISDN) which automatically reports whether a fax is transmitted successfully by transmitting it to a sending side fax.

First, in the present specification, when the terms of the sender and the sender are defined, the sender refers to a person or a fax using a communication channel set to the opposite fax through a telephone number, and the sender transmits the fax data through the set communication channel. It means people. Therefore, in the present specification, the sender and the sender are the same person or fax, and both the sender and the sender are used interchangeably.

Faxes are widely used as office equipment for transmitting and receiving fax data in the form of images between faxes.

In such a fax, when sending fax data by a fax sender, the sender did not know whether the receiving party correctly received the fax data transmitted by external factors such as the network connected to the fax and the status of the receiving fax.

In general, the fax provides a mechanism for confirming that the transmitted fax data is correctly received by the receiver. The fax connected to the Public Switch Telephone Network (PSTN) is used by the sender of the fax data. Register the fax sender's telephone number with the Transmitting Subscriber Identification (TSI) command according to the International Telegraph and Telephone Consultative Committee (CCITT) Recommendation T.30, and use it on the receiving side to report the receiving status to the sending side. Could.

However, if the sending user does not register the correct calling phone number in the information field of the TSI command, or does not register the calling phone number at all, the acknowledgment reporting message sent by the receiving end is not correctly delivered to the sending end. .

Therefore, in order to know whether the outgoing fax data has been correctly transmitted, the sending fax user registers his / her telephone number correctly, and the receiving side transmits the reception of the fax message to the sending party using this registration information, or the sending user or Since the receiving user needs to check the fax reception by manually calling again, the users have a problem in checking the fax data transmission.

Accordingly, an object of the present invention is to determine whether the receiving side fax itself is successful in receiving the fax data using the calling party's telephone number provided by the ISDN, and transmits the receiving side to the sending side fax in a predetermined message format. In this case, the sending fax user can easily know whether the receiving fax is successfully received by the receiving fax.

And a field for storing a flag indicating whether the fax data has been successfully received.

FIG. 5A shows a message format for notifying a fax data transmission side of a fax data transmission side according to the present invention, and FIG. 5B shows a message format for notifying a fax data transmission side of a fax data transmission side according to the present invention.

Hereinafter, an operation of a method of transmitting an acknowledgment message using a caller's phone number in an integrated information communication network (ISDN) of the present invention will be described with reference to FIG. 3.

First, the central processing unit 10 of the receiving side receiving the fax data establishes a communication channel by connecting the calling line and the call line (step: S300).

After setting the communication channel, the central processing unit 10 receives the caller's telephone number of the fax sender from the integrated information communication network (ISDN) via the network unit 60 (step: S310).

After receiving the sender's telephone number of the fax sender from the ISDN, the receiver receives the fax data of the fax sender through the established communication channel (step S320).

After receiving the fax data of the fax sender through the established communication channel, predetermined information regarding the received fax data is stored in the memory 20 (step S330).

At this time, the predetermined information includes the caller's telephone number of the fax data, the receiver's telephone number of the fax data, the time at which the fax data was received, the number of pages of the received fax data, and the reception of the fax data, as shown in FIG. Information on the flag indicating success or failure.

Meanwhile, the recipient's telephone number of the fax data is to be used as a contact number of the message sender when transmitting this information to the sender later, and the time at which the fax data is received is stored using the real-time clock of the multifunction device. The number of received pages and the shared no information can be obtained through a general fax communication protocol.

After storing predetermined information about the received fax data, the message is transmitted to the caller's telephone number according to whether the fax data is successfully received (step S340).

Looking at this in more detail, first set the fax and communication channel corresponding to the sender's telephone number of the information on the received fax data stored in the memory 20 (step: S341)

On the other hand, since the detailed process of setting the channel is a very general technique it will be omitted.

After setting a communication channel with a fax corresponding to the sender's telephone number, it is determined whether the reception is successful through a flag indicating whether reception is successful among the information on the received fax data stored in the memory 20 (step: S342).

Preferably, the flag value is '0' when the reception of the fax data is successful, and the flag value is set to '1' when the reception of the fax data has failed.

As a result of determining whether the reception of the fax data is successful, when the reception of the fax data fails (that is, when the flag value is '1'), the fax reception failure message regarding the failed reception of the fax data is transmitted as shown in FIG. 5B (step S343). .

If it is determined that the reception of the fax data is successful, if the reception of the fax data is successful (that is, the flag value is '0'), the fax reception success message regarding the successful reception of the fax data is transmitted as shown in FIG. 5A (step: S344).

Although the preferred embodiments of the present invention have been described in detail above, those skilled in the art will appreciate that the present invention may be modified without departing from the spirit and scope of the invention as defined in the appended claims. It will be appreciated that modifications or variations may be made. Therefore, changes in the future embodiments of the present invention will not be able to escape the technology of the present invention.

As described above, according to the present invention, by using the calling party's telephone number provided by the ISDN, it is determined by the receiving fax itself whether the receiving data is successful. The sending fax user can easily know whether the receiving fax is successfully received by the receiving fax.
