Abstract

PURPOSE:To retransmit an unreached data to a designated destination with simple operation by providing an unreached data detection means, a notice means, a data retrieval means and an unreached data retransmitting means. CONSTITUTION:When an unreached data takes place, a CPU 25 transmits an unreached data generation notice to a transmission terminal device 5. When the operator of a terminal device receives notice of generation of unreached data, the operator connects the terminal device 5 and a data store exchange 1 to input again a serial number. A storage device 15 retrieves a data corresponding to the serial number and retransmits a data corresponding to the serial number obtained by a reception terminal device 11 being the unreached destination. When the data is sent within the managing time, it is informed to the terminal device 5, and when not, the notice of generation of unreached data is informed again to the terminal device 5. Thus, when any unreached data takes place, the operator at the transmission terminal device retransmits the data to the reception terminal device being the unreached destination by having only to input the serial number.

Description

DETAILED DESCRIPTION OF THE INVENTION [Technical Field of the Invention] The present invention relates to an unreached destination retransmission method in a data exchange method for transmitting data between a transmitting terminal and a receiving terminal via a data storage and exchange device.

[Technical Preface of the Invention II] In such a data exchange system, when data is transmitted from a transmitting terminal to a receiving terminal via a data storage and exchange device, the data received by the data storage and exchange device is transmitted for a certain period of time (management time). ), or if it cannot be transmitted to a certain receiving terminal within a certain call interval (within the number of managed calls), so-called undelivered data may occur. This occurs, for example, when a destination receiving terminal is transmitting data from another transmitting terminal and the transmitting terminal attempts to transmit data to this receiving terminal.

For this reason, the following methods have conventionally existed for processing undelivered data.

(1) When undelivered data occurs, the occurrence of undelivered data can be displayed on the display connected to the data storage and exchange device, and the operator of the data storage and exchange device can notify the sending terminal. The operator of the transmitting terminal then enters the data again.

(2) When undelivered data occurs, an undelivered list is output to the sending terminal, the undelivered destinations are notified, and the operator of the transmitting terminal sends the data via a different route or inputs the data again.

[Problems in the Background Art] However, in the above-mentioned method of processing undelivered data, the operator of the sending terminal must re-enter the data and send it to the undelivered destination, which requires the operator to perform complicated data entry work. There was a problem that the process had to be repeated multiple times.

[Object of the Invention] Therefore, in order to solve the above-mentioned problems, it is an object of the present invention to provide an undelivered destination reproduction method that can resend data to a specified destination with a simple operation even if undelivered data occurs. .

[Summary of the Invention] In order to achieve the above object, the present invention includes undelivered data detection means for detecting the occurrence of undelivered data, notification means for notifying the transmitting terminal of the occurrence of undelivered data, and a transmitting terminal that detects undelivered data. a data search means for searching for data corresponding to the serial number among the data stored in the data storage and exchange device when a serial number is inputted after receiving a notification of the occurrence of the data; It is characterized by comprising undelivered data retransmission means for transmitting undelivered data to a receiving terminal of an undelivered destination.

[Embodiment of the Invention] An embodiment of the invention will be described in detail below based on the drawings. FIG. 1 is a block diagram showing the outline of this embodiment. A transmitting terminal 5.7 and a receiving terminal 9.11 are connected to the data storage and exchange device 11 via the switching network 3. In FIG. The communication control means 13 of the data storage and exchange device 1 stores the data and destination sent from the sending terminal 5.7 via the exchange network 3 into a storage bag @15.
and store this data in the receiving terminal 9 or 11 on the destination side.
Controls transmission to. The undelivered data detection means 17 detects the occurrence of undelivered data, and if undelivered data occurs, it notifies the notification means 19 of this. The notification means 19 transmits the notification via the communication control means 13 when undelivered data occurs, and the elementary means 21 informs the operator of the transmitting terminal 5 or 7 of the occurrence of undelivered data and inputs the serial number. , the storage device 15 is searched for data corresponding to this serial number. The undelivered data retransmission means 23 sends the undelivered data retrieved by the data retrieval means 21 to the storage device 1.
5 and transmits it to the unreached receiving terminal 9 or 11.

FIG. 2 is a diagram showing the hardware configuration of the unreached destination retransmission system according to this embodiment. As shown in the figure, the data storage and exchange device t1 is a communication control device 13-1.13-
2, a storage device 15 composed of a magnetic disk or magnetic tape, and a central processing unit! (CPU) Consisting of 25,
These are connected by a bus 27. The data storage and exchange device 1 is connected to a bus 27 and is connected to a bus 29.
A console typewriter 33 and a display 35 are connected via 31.

Next, the operation of this embodiment will be explained. When data is currently being transmitted from the other transmitting terminal 7 to the receiving terminal 11, the data is broadcast from the target transmitting terminal 5 to the receiving terminals 9 and 11 via the data storage and exchange device 1. Assume a case where communication is carried out. At this time, data is transmitted from the transmitting terminal 5 to the receiving terminal 9, but the transmitting terminal
If the transmission to the terminal 1 is too long and the broadcast communication management time has elapsed, data cannot be transmitted from the transmitting terminal 5 to the receiving terminal 11, resulting in undelivered data.

FIG. 3 is a flowchart showing the operation of this embodiment. The CPU 25 monitors the occurrence of undelivered data in step 301, and when undelivered data is generated, transmits an undelivered data occurrence notification to the sending terminal 5 in step 303. This notification of unreached data is 5.7 for each terminal.
．． If 9.11 is sent by facsimile, it is sufficient to transmit the fact that non-delivery has occurred, the serial number, and the first page of the transmission data using a facsimile signal. If each terminal is a personal computer, it is sufficient to send the fact that undelivered data has occurred, the serial number, and the first page of the transmitted data as a personal computer signal. The first page of transmission data is often sent because the sender, destination, etc. are written on this page, and when the operator of the transmission terminal 5 sees this, he or she can immediately identify which data it is. This is to make it easier to understand.

When the operator of the transmitting terminal 5 is notified of the occurrence of undelivered data, the operator connects the transmitting terminal 5 and the data storage/exchange device 1 as necessary and inputs the serial number again in step 305.

In step 307, the storage device 15 is searched for data corresponding to the serial number.

In step 309, the data corresponding to the serial number obtained in step 307 is retransmitted to the destination receiving terminal 11 that has not been reached.

If the data can be transmitted within the management time in step 311, this is notified to the transmitting terminal 5 in step 313, and if not, an undelivered data occurrence notification is again transmitted to the transmitting terminal 5.

If undelivered data occurs due to the above configuration, the sending terminal 5
The operator simply inputs the serial number, and the data is retransmitted to the receiving terminal 11 of the undelivered destination.

Although the present embodiment has been described using two transmitting terminals and two receiving terminals, it is needless to say that the number is not limited to this number.

[Effects of the Invention] As described above in detail, according to the present invention, undelivered data can be resent to a designated destination with a simple operation.
