Description

  The present invention relates to a FAX gateway apparatus that can receive FAX data even with a terminal that does not have a FAX reception function (including a terminal that has a FAX reception function but does not support a protocol).

  In a conventional fax using a public line, the fax can be received only by a terminal having a fax function.

  On the other hand, IP (Internet Protocol) -FAX using SIP (Session Initiation Protocol) has begun to spread (see, for example, Patent Documents 1 to 5), and a number is not assigned to a FAX terminal but to a person. By assigning a number, each person can designate a terminal that receives a FAX.

  By the way, protocols such as T4, T37, and T38 recommended by ITU-T (International Telecommunication Union Telecommunication Standardization sector) are mainly used for the FAX data transmission method in FAX communication, but the receiving terminal is not compatible. If this happens, communication cannot be performed.

For this reason, there is a technique for performing communication by negotiating a transmission control procedure by presenting a FAX data transmission system included in the FAX transmission side terminal and allowing the reception side terminal to select it.
JP 2005-51802 A JP 2005-80025 A JP 2004-229296 A JP 2004-201276 A Japanese Patent No. 3645191

  The following problems have been pointed out in the conventional technology described above.

  (1) Even if it is attempted to perform communication by selecting a means according to the data transfer speed of the receiving terminal and the FAX data transmission method at the time of FAX transmission, communication is performed if the other terminal cannot cope with the means presented as a selection candidate. Can not do. In addition, the FAX data transmission method presented as a selection candidate at this time is based on the assumption that the receiving device is a FAX terminal, and the receiving side is not a FAX terminal but a printer or PC (Personal Computer). Cannot communicate.

  (2) Since the IP-FAX transmission by SIP is performed not for the conventional telephone number but for the SIP user identification ID such as SIP-URI (Uniform Resource Identifiers), whether or not the terminal of the identification ID is a FAX device. Is unknown to the sender. Therefore, when the sender surely wants to send FAX data to the other party, the sender must know in advance that the other terminal is a FAX apparatus.

  (3) If the data received by FAX does not need to be output on paper, but only to be captured on a PC, the output paper is converted into image data by a scanner or the like and sent to the PC. It must be complicated.

  (4) When transmitting highly confidential information by FAX, if the person to be received is absent, the confidential information remains output on paper, which causes a security problem.

  (5) If the receiving terminal cannot receive data due to data processing or a failure or the like, the sender cannot know the detailed reason and must transmit again.

  (6) Since IP-FAX normally does not incur a telephone charge between users of the same service provider, a malicious user may send FAX data, which wastes resources and hinders important FAX reception. It becomes.

<Operation>
FIG. 7 is a sequence diagram showing an overall processing example of a system to which the above-described FAX gateway device 6 is applied.

  In FIG. 7, user registration (service registration) is performed to the SIP server 5 by SIP from the PC 8 on which the user has logged in, the printer 7 of the transfer destination device, (PC 8), the FAX apparatus 9, and the FAX gateway apparatus 6 at the time of activation. (Steps S101 to S103). When the user registers with the SIP server 5, the FAX gateway device 6 is set to receive a fax addressed to its own URI by proxy by designating the FAX gateway device 6 in the Contact header of the SIP message.

  Next, the FAX gateway apparatus 6 periodically makes a presence request to the PC 8 and the transfer destination device by SIP, and acquires presence information (transfer setting information in FIG. 5 and transfer destination device specific information in FIG. 6) by the response. (Steps S104 to S107).

  Thereafter, when there is a FAX call addressed to the user from the FAX apparatus 2 (step S108), the FAX gateway apparatus 6 responds by proxy and establishes a session with the transfer destination apparatus according to the transfer setting information (FIG. 5) (step S108). S109).

  Then, the FAX gateway apparatus 6 notifies the FAX apparatus 2 of completion of data transfer preparation (step S110), receives FAX data from the FAX apparatus 2 (step S111), and is predetermined according to transfer destination device specific information (FIG. 6). The data is converted into the above protocol and transferred (step S112). When a data end notification is received from the FAX apparatus 2 (step S113), a data end notification is sent to the transfer destination device (step S114), and the process ends.

  Hereinafter, the operation of each unit will be described in more detail. In addition, the positional relationship of each figure used for the following description is shown in FIG.

  FIG. 8 is a flowchart showing a processing example of the FAX gateway device 6.

  In FIG. 8, the FAX gateway device 6 performs user registration (service registration) with the SIP server 5 by SIP at the time of activation (step S201).

  Next, the FAX gateway apparatus 6 acquires transfer destination device specific information (FIG. 6) including transfer setting information (FIG. 5) from the user and information such as a desired communication method from the transfer destination device by the SIP presence function. Then, it is stored in the storage device 65 (FIG. 2) in a table format (step S202).

  Thereafter, when the FAX gateway device 6 detects an incoming fax addressed to the user (step S203), the unique information of the transfer destination device designated as the transfer destination is read from the storage device 65 (step S204).

  Then, it is determined whether or not the transfer destination device is in a state where data can be received (step S205). If the transfer destination device is in an online state, it is determined that data can be received (Yes in step S205). The operation when the transfer destination device is not ready to receive data (step S212) will be described later.

  When the transfer destination device is ready to receive data (Yes in step S205), it is determined what the communication method desired by the transfer destination device (step S206), and the transfer destination device is connected to the transfer destination device using the desired communication method. Session is established (steps S207 to S210), data is converted according to the procedure according to each protocol control, and the data is transferred to the transfer destination device (step S211).

  It is also possible to specify the PC 8 used by the user as the FAX destination device for the user. In this case, information including the transfer setting information and the destination device specific information is used in the presence response (step S202). Notice.

  Further, when the user must unavoidably delete the registration from the SIP server 5 due to a PC shutdown or the like when returning home, the user can register the user with the SIP server 5 from the FAX gateway device 6 so that the user can Data transfer by the FAX gateway device 6 can be used even when the user is absent.

  FIG. 9 is a flowchart illustrating a processing example of the transfer destination device.

  In FIG. 9, the transfer destination device performs user registration (service registration) with the SIP server 5 by SIP at the time of activation (step S301).

  Next, the transfer destination device notifies the transfer destination device specific information (FIG. 6) as a response to the request from the FAX gateway device 6 using the SIP presence function (step S302).

  Thereafter, the transfer destination device waits for data transfer from the FAX gateway device 6 (step S303), and when the proxy reception FAX gateway device 6 receives a FAX addressed to the user (step S304), the device specific information is used. Data is received from the FAX gateway apparatus 6 by the notified communication protocol (step S305).

  Note that the transfer destination device does not need to be a FAX apparatus, and may be a printer or a PC. As a typical usage method, if the transfer destination device is a printer, FAX data transferred by designating the IPP protocol or LPR protocol can be printed as printer data. If the transfer destination device is a PC, the SMB protocol or the like can be printed. Fax data can be acquired as image data in the PC folder using the FTP protocol. Furthermore, image data can be received by mail by specifying a mail address such as direct SMTP from the PC instead of the data transfer destination device. It should be noted that the user name, password, etc. necessary for writing to the PC folder or mail transmission are set in supplementary information of the transfer setting information (FIG. 5) at the time of presence notification.

  FIG. 10 is a flowchart showing a processing example of the FAX reception control unit 605 mainly of the FAX gateway device 6. This process is a detailed version of step S211 in FIG.

  In FIG. 10, after establishing a session with the transfer destination device (step S401), the FAX gateway device 6 is ready for data reception by transmitting an ACK (Acknowledge) message to the transmitting terminal that has transmitted the FAX. A response to that effect is made (step S402).

  Thereafter, reception processing of FAX data is performed, but when normal FAX data cannot be transmitted at once, etc., since it is divided and transmitted into a plurality of packet data, loop processing is performed (steps S403 to S408), and individual division is performed. When the packet data is received (step S404), the packet data is transferred to the transfer destination device (step S405), and an error or the like is detected in the transfer to the transfer destination device before the reception of all FAX data is completed. If it is found that the error could not be made (No in step S406), an error is notified to the calling terminal at that time (step S409). If all data has been received normally (Yes in step S407), the sending terminal is notified that data reception has been completed normally (step S410).

  FIG. 11 is a flowchart showing a processing example of mainly the presence control unit 606 of the FAX gateway apparatus 6. This process is a detailed version of step S212 in FIG.

  In FIG. 11, when the transfer destination device is not in a state where data can be received (step S501), the response method in the reception disabled state of the transfer setting information (FIG. 5) of the destination user is read (step S502).

  Next, the response method in the reception disabled state is determined (step S503), and if the content is “notify reception disabled” (CASE 1), the FAX gateway device 6 sends a message indicating that reception is disabled to the calling terminal. Is transmitted (step S504), and if the mail address of the destination user and the administrator of the transfer destination device designated as the transfer destination is set in the device specific information (FIG. 6), it is received by those persons. The fact that an unacceptable response has been made is notified by mail (steps S505 and S506), and the SIP session is terminated (step S511).

  In addition, when the response method in the reception disabled state is the content that “the proxy gateway stores and stores” (CASE 2), the FAX gateway device 6 prepares for data reception by transmitting an ACK message to the calling terminal. Is received (step S507), and then the FAX data transmitted from the calling terminal is intercepted and stored in the storage device (step S508). In addition, when the mail address of the destination user and the administrator of the transfer destination device specified as the transfer destination is set in the device specific information (FIG. 6), proxy reception and storage were performed for those users This is notified by mail (steps S509 and S510), and the SIP session is terminated (step S511).

  If the response method in the reception disabled state is not specified by the destination user (CASE 3), the response method set in advance by the administrator of the FAX gateway device 6 is read (step S512), and the response method is read out. Process according to

  FIG. 12 is a flowchart showing a processing example mainly of the data transfer control unit 609 of the FAX gateway apparatus 6. This process is another example in which step S211 of FIG. 8 is detailed.

  In FIG. 12, a session is established by a protocol designated by the transfer destination device (step S601), preparation completion is notified to the calling terminal (step S602), FAX data is received (steps S603 and S604), and this data is stored. At any time, the data is stored in a storage device in a predetermined data format (step S605).

  If the allowable reception data amount specified by the device specific information has been exceeded during FAX data reception (Yes in step S606), the transfer destination device is notified of an allowable data amount excess (step S608), and the transfer destination If the e-mail address of the destination user and the administrator of the transfer destination device specified as the transfer destination is set in the device specific information (FIG. 6) without transferring the data to the device, to those persons It is notified by e-mail that data has been stored in the FAX gateway device 6 due to the overage (step S609). Other processes are the same as those shown in FIG.

  FIG. 13 is a flowchart illustrating a processing example of the FAX reception control unit 605 of the FAX gateway apparatus 6.

  In FIG. 13, after the presence information is acquired (step S701), if an incoming fax is detected (step S702), the incoming call rejection information is read out from the forwarding setting information of the destination user (step S703).

  At this time, if the calling terminal is the object of incoming call rejection (Yes in step S704), the FAX gateway apparatus 6 sends a rejection response to the calling terminal (step S705).

  If the email address of the destination user and the administrator of the transfer destination device specified as the transfer destination is set in the device specific information (FIG. 6), an incoming call rejection response has been sent to those persons Is notified by e-mail (steps S706 and S707). If the call is not rejected (No in step S704), normal processing as shown in FIG. 8 is performed (step S708).

<Summary>
As described above, in the present invention, even when the FAX destination device is a printer or a PC, the FAX gateway device 6 performs data reception as a FAX terminal, and identifies the communication method desired by the destination device. Data can be transferred in a suitable manner. In other words, the FAX sender does not need to confirm whether the SIP user identification ID specified as the destination is a FAX terminal, and if only the user identification ID is specified, the FAX gateway apparatus 6 delivers the image data to the destination by some method. be able to.

  In addition, by designating a PC or mail address as a data transfer destination, it is not necessary to output the data on paper, and it is possible to transfer the data directly to the PC when it is simply stored in the PC. This is superior in terms of security compared to a conventional FAX in which highly confidential information is transmitted by FAX and is output on paper even when no person is present.

  One of the advantages of SIP-based IP-FAX is real-time performance (in the case of conventional Internet FAX using mail, the time when the sender sent the data and the time when the receiver received the data were not always in the same period. However, there is a risk that the real-time property may be impaired because data is transferred by the FAX gateway device 6 as in the present invention. However, since the normality of the transfer is confirmed every time the data transmitted by dividing the packet is transferred to the transfer destination device, and an abnormality occurs in the data transfer, it is notified immediately. It is possible to ensure substantially the same real-time property as IP-FAX.

  Further, even when the device designated as the FAX destination cannot receive data due to data processing or failure, the FAX gateway device 6 responds to the sender on behalf of the sender, so that the detailed reason is sent to the sender. Can be notified. Further, if necessary, it is possible to notify the administrator that there has been a FAX incoming request when communication is disabled.

  Even when the device designated as the FAX destination cannot receive data due to data processing or failure, the FAX gateway apparatus 6 receives and accumulates data on behalf of the sender, so that the sender can save time. There is no need to send again. In this case, real-time processing is applied, but when this becomes a problem, the FAX gateway apparatus 6 can make a notification to the sender in advance using SDP (Session Description Protocol) information of the SIP message. It is also possible to transmit after recognizing it.

  In addition, it is possible to specify the operation when the transfer destination device that is the FAX transfer destination is in a state where data cannot be received. This is based on the premise that the transfer destination device notifies the device specific information. Therefore, this is not the case when the power is cut off. However, by preliminarily specifying an operation when nothing is specified in the FAX gateway device 6 due to reasons such as power-off of the transfer destination device, it becomes possible to perform a response according to that.

  Also, a device that receives a FAX usually does not know how much data is transmitted. Therefore, the device is occupied until the processing is completed, for example, when very large data is sent. However, such a problem can be solved by notifying the FAX gateway apparatus 6 of the upper limit of the data amount allowed in advance. In addition, since it is possible to notify the destination user and administrator, large data can be transferred from the FAX gateway device 6 by selecting a time when the transfer destination device is not used frequently.

  In addition, since IP-FAX normally does not incur a telephone charge, there is a great possibility that a malicious user sends FAX data. However, since it is possible for the FAX gateway apparatus 6 to reject an incoming call from a specific partner before reaching the transfer destination device, even a device that does not have an incoming call rejection function rejects an incoming call from a malicious user. Can do. Further, the transfer destination device manager or the destination user can know that fact.

  The present invention has been described above by the preferred embodiments of the present invention. While the invention has been described with reference to specific embodiments, various modifications and changes may be made to the embodiments without departing from the broad spirit and scope of the invention as defined in the claims.
