Description

  The present invention relates to a communication terminal device, a communication method, and a communication program, and more particularly to an archive of transmission / reception data.

It is known to archive Internet facsimile e-mail, G3 facsimile, and the like in a communication terminal device such as a network multifunction peripheral (Patent Document 1). The importance of archiving is increasing so that personal information is not leaked, confidential information of companies and the like is thoroughly managed, and communication terminal devices are not used illegally. However, little consideration has been given to the possibility of archiving due to communication failure.
Japanese Patent Laid-Open No. 2004-40600

  An object of the present invention is to ensure that transmitted / received data can be archived even if a communication failure or the like occurs.

  According to the present invention, in a communication terminal device having an archiving means for archiving transmission / reception data, the archiving means stores the transmission / reception data in its own memory, and then transfers it to the archive destination. The transmission / reception data archived from the memory of the machine is erased.

Preferably, if transfer to the archive destination fails, after waiting for a predetermined time, it is retransferred to the archive destination and the number of transfers is counted, and when the counted value reaches a predetermined value, a notification is given to the outside.
Particularly preferably, when storing the transmission / reception data in its own memory, the archiving unit associates the archive destination data with the transmission / reception data, and executes the transfer to the archive destination according to the corresponding archive destination data. . Here, “corresponding” means that the archive destination is described in the archive data file, or that the archive data file and the archive destination data file are linked.

Further, according to the present invention, in a communication method for transmitting / receiving data and archiving the transmitted / received data, the transmitted / received data is stored in its own memory, then transferred to an archiving destination, and if the transfer is successful, it is The received transmission / reception data is erased.
Preferably, if the transfer to the archive destination fails, the data is transferred again to the archive destination after waiting for a predetermined time, and the number of transfers is counted. When the counted value reaches a predetermined value, an external notification is given.

  The present invention also relates to a program for a communication terminal device that performs transmission / reception of data and archives the transmission / reception data, stores the transmission / reception data in the memory of the own device, and then transfers the command to the archive destination. And a command for erasing the transmitted / received data archived from the memory of the own device.

  In this specification, the description regarding the communication terminal apparatus also applies to the communication method and the communication program as it is, and conversely, the description regarding the communication method also applies to the communication terminal apparatus and the communication program. In the embodiment, a network multifunction peripheral that includes a scanner and a printer and transmits and receives image data via e-mail via a network will be described. However, the type of communication terminal device itself is arbitrary.

  In this invention, the data to be archived is stored in its own memory and then transferred to the archive destination. Therefore, even if the transfer fails due to a communication failure or the server of the archive destination being down, the archive data is stored in its own memory. Remains, so the archived transmission / reception data (archive data) will not be lost. Further, when the archive transfer is successful, the archive data is erased from the memory of the own device, so that the memory does not overflow.

  If the number of failed transfer to the archive destination is counted and notified to the administrator, etc. above a predetermined value, the archive destination host has been removed, the archive destination address setting is incorrect, etc. Since it is possible to detect errors that are not expected to be restored, it is possible to take measures such as changing the archive destination.

  If the transfer to the archive destination is repeated, the setting of the archive destination may be changed during that time. When searching archive data later, there are many cases where the time of transmission / reception data is used as a clue, and it is convenient to know the archive destination based on the time of first transmission / reception. Therefore, if the archive data and the archive destination are stored in association with each other, even if the setting of the archive destination is changed later, the archive data is not affected immediately and can be archived to the archive destination of the initial setting.

  In the following, an optimum embodiment for carrying out the present invention will be shown.

  1 to 6 show an embodiment of the network multifunction device 2 as an example. The network MFP 2 is connected to a client 6 such as a personal computer, a mail server 8 and an archive destination server 10 via a LAN 4. The archive destination server 10 includes a shared folder according to the SMB (Server Message Block) protocol, or receives and stores data for archiving by SMTP, FTP, or the like. The LAN 4 is connected to the Internet 14 via the router 12. The network MFP 2 includes a LAN interface 16, a scanner 17, and a printer 18. A G3 facsimile processing unit 19 transmits and receives G3 facsimile via a PSTN (public telephone network) 20. Note that the data to be archived is an electronic mail transmitted / received through at least the LAN interface 16, which includes Internet facsimiles, and G3 facsimile documents may also be archived.

  The network MFP 2 includes an HTTP server function processing unit 21, an SMTP server function processing unit 22, and an Internet facsimile function processing unit 23. The network multifunction peripheral 2 provides a Web page to the client 6 as an HTTP server, sends / receives e-mail to / from an external terminal connected to the client 6 or the Internet 14, and the image read by the scanner 17 by the Internet facsimile function processing unit 23. Data, image data received from the public telephone line network 20, and the like are transmitted as an Internet facsimile in an e-mail format. Similarly, the Internet facsimile function processing unit 23 receives an Internet facsimile in an e-mail format, prints it by the printer 18, transfers it to the client 6, and performs G3 facsimile transfer from the G3 facsimile processing unit 19.

  The archive processing unit 24 archives e-mails to be transmitted / received, and also archives G3 facsimiles transmitted / received by the G3 facsimile processing unit 19. For the archive data, electronic mail or G3 facsimile may be used as they are, or the image data portion in these data may be compressed. The protocol used for archive transfer is, for example, SMB, SMTP, or FTP. The archive processing unit 24 sends / receives e-mails and G3 facsimiles, adds an archive destination setting to the communication data (archive data) file, stores the file in the communication memory 28, and then sets the archive setting. The archive data is transferred to the archive destination server 10 according to the protocol in FIG. When the transfer is successful, the archive processing unit 24 deletes the archive data file from the communication memory 28, and does not delete the file if the transfer fails.

  The archive error management unit 25 is activated due to failure of archive transfer, and performs retransfer after waiting for a predetermined time and counts the number of transfer failures. When the number of failures exceeds a predetermined value, the archive error management unit 25 performs processing such as displaying on an operation panel (not shown) or transmitting information to the administrator terminal 5.

  The image memory 26 stores image data read by the scanner 17 and image data to be printed by the printer 18, and the communication memory 27 succeeds in transferring data, G3 facsimile data, and archive data communicated via the LAN interface 16. Remember until you do. The G3 facsimile processing unit 19 may not be provided, and the embodiment may be applied to an archive such as a personal computer or the mail server 8. The archive data may be stored in the network multifunction device 2 and the storage location is arbitrary.

  FIG. 2 shows an archive program 30 according to the embodiment. A communication memory storage instruction 31 stores setting data such as an archive destination address in the archive data in the communication memory 28. The archive transfer instruction 32 transfers the archive data stored in the communication memory 28 according to the setting data of the transfer destination described in the file, and when the transfer is successful, deletes the archive data file from the communication memory. The error management instruction 33 counts the number of times the archive transfer has failed, calls the archive transfer instruction 32 every time a predetermined time elapses, causes the archive data to be retransferred, and notifies the outside when the number of failures exceeds a predetermined value. .

  FIG. 3 shows an archiving procedure in the embodiment. As data is transmitted / received, archive data is generated (steps 1 and 2), and setting data of the archive destination is added to the transmitted / received data and stored in the communication memory (step 3). After saving, the data is transferred to the archive destination (step 4), and when the transfer is successful, the corresponding archive data is deleted from the communication memory and the process ends (steps 5 and 6). If the transfer fails, when the number of transfers exceeds a predetermined value n, the administrator is notified by sending it to the administrator's terminal or displaying it on the operation panel (steps 7 and 9). Transmit (step 8).

  FIG. 4 shows a change in state until transmission / reception data is archived. The transmission / reception file 41 is added with the archive destination data after completion of the transmission / reception, stored in the communication memory as the archive file 42, and transferred to the archive destination according to the archive destination data in the file. If the transfer is successful, the archive file 42 is deleted from the communication memory. If the transfer fails, the number of failures is counted, and the transfer is repeated after waiting for a predetermined time. When the number of failures exceeds a predetermined value, processing such as notifying the administrator terminal is performed.

In the embodiment, the following effects can be obtained.
(1) Even if transfer to the archive destination fails, the archive data remains in the communication memory and can be transferred again.
(2) If the transfer fails repeatedly, it can be estimated that the archive destination has a failure that is not primary. In such a case, the administrator can know.
(3) Even if the archive destination setting is changed while the archive transfer is repeated, in principle it can be transferred with the settings at the time of archive data generation.

Since the archive destination is not expected to be restored, it may be possible to repeat the transfer according to the data in the archive file even though the setting of the archive destination is changed. To prevent this situation, change the setting of the archive destination data, ignore the data in the archive file and follow the new setting, and enable the archive destination data in the archive file even after changing the setting. It is good to provide a mode.
