Description

  The present invention relates to a facsimile apparatus, a facsimile communication system, a facsimile communication control method, a facsimile communication control program, and a recording medium. The present invention relates to a facsimile communication control program and a recording medium.

  In facsimile communication in which image data is transmitted and received using a line, when a call is made from the calling side to the called side and the called side answers, the facsimile communication is performed according to the facsimile communication procedure, and the image data is received from the calling side. To the side.

  In the facsimile communication, if the called party cannot receive the call due to busy or out of paper, the facsimile communication cannot be established and the image data cannot be transmitted.

  In this case, if the traffic of facsimile communication is very high as in the product order receiving center, for example, if the image data of the order slip is urgently transmitted from the branch to the product order receiving center, If the machine receives new facsimiles one after another, even if repeated calls are repeated from the branch office facsimile machine to the facsimile machine at the product order receiving center using the recall function, a situation may occur in which transmission cannot be performed for a long time. is there.

  Therefore, conventionally, when a caller has called a callee and the callee has not been able to transmit image data due to busy or the like, the caller has set the IP address of the callee. The image data is stored and stored, and the caller responds with an incoming call, but if the image data is not transmitted within a preset time, the IP address of the other party of the incoming call There has been proposed a network facsimile apparatus that transmits stored image data to a destination when the IP address matches an IP address stored in advance (see Patent Document 1).

  However, in the prior art described in the above publication, when the incoming call side is connected from the incoming call side to the outgoing call side, the incoming call cannot be answered because the previous incoming call was busy. In order to determine whether or not a call is made to the caller of the incoming call, it is checked whether or not image data is transmitted from the caller within a preset time. If the image data is not transmitted within the time, it is determined that the call is an incoming call from the other party that made the call based on the IP protocol, and the stored image data is transmitted. Therefore, it takes time to determine whether the other party that received the call was the first party that could not send the image data and the processing speed was reduced. And improve the transmission of image data There was a need for improvement.

  In other words, in facsimile communication, the time from the completion of call connection to the start of the facsimile protocol is stipulated in the ITU-T recommendation. The program control signal is transmitted from the terminal, and the facsimile communication protocol is advanced after waiting for a response from the calling side. Therefore, in the prior art described in the above publication, whether the facsimile control signal from the called side does not reach the calling side and the image data is not transmitted, or the calling side responds to the previous incoming call. It is difficult to distinguish whether image data has not been transmitted in order to realize the above, and there is a possibility that an appropriate procedure cannot be executed. It is necessary to confirm that no image data is transmitted, and there is a need for improvement in order to increase the processing speed of facsimile communication.

By being installed in the ROM or the magnetic disk unit 6, it is constructed as a facsimile apparatus that executes a facsimile communication control method for reliably transmitting urgent image data described later. This facsimile communication control program is a computer-executable program written in a legacy programming language such as assembler, C, C ++, C #, Java (registered trademark) or an object-oriented programming language, and is stored in the recording medium. And can be distributed.

  The call connection message encoding unit 8, the call connection message decoding unit 9, the call ID generation unit 10, the call connection message transmission unit 11, and the call connection message reception unit 12 function as a call connection message exchange unit as a whole. The CPU functions as an emergency transmission request control unit and an emergency transmission control unit on the calling side, and also functions as an emergency response standby control unit and an emergency response control unit on the called side.

  Next, the operation of this embodiment will be described. When making a facsimile call, the facsimile apparatus 1 according to the present embodiment adds a parameter for designating a callback and a call ID for specifying the call and cannot transmit image data. When there is a call to which a parameter for specifying a call by callback and a call ID are added, image data that could not be transmitted in response to the call is transmitted to the destination.

  In the following description, the facsimile apparatus 1 is installed on both the calling side and the called side, and for the sake of clarity, the facsimile on the side that makes the call first with a callback request is described. The apparatus 1 is called a calling terminal Ta, and the facsimile apparatus 1 on the receiving side is called a called terminal Tb. Then, it is assumed that the called terminal Tb calls back to the calling terminal Ta in response to the callback request.

  When the user of the calling terminal Ta wants to transmit urgent image data (facsimile data), he / she sets a transmission document on the scanner unit 2 of the calling terminal Ta and operates the operation display unit 4 to operate the emergency transmission mode and the transmission destination. And a transmission instruction designating the image data to be transmitted.

  The calling terminal Ta performs emergency facsimile communication control processing on the calling side as shown in FIG. That is, the calling terminal Ta checks whether there is a call request during standby (step S101), and if there is a call request, checks whether the call request is a call request for which emergency transmission is designated (step S101). Step S102).

  When emergency transmission is not specified in step S102, the call connection message encoding unit 8 generates a normal call connection message and transmits it from the call connection message transmission unit 11 to the partner terminal (step S103), and emergency transmission is specified. If so, the call connection message encoding unit 8 adds a callback request parameter for emergency transmission request (emergency transmission request parameter) to an area where the terminal of the call connection message can freely set parameters (step S104). ), The call connection message transmission unit 11 transmits the call connection message to which the parameter is added (step S103). The calling terminal Ta adds a callback request parameter to the call connection message as a parameter for the emergency transmission request, for example, as shown in FIG. 3 and calls the emergency transmission request as call specifying information. An ID (CallID) is set and transmitted.

  When the calling terminal Ta transmits a call connection message to the called terminal Tb, the calling terminal Ta checks whether the partner terminal (called terminal Tb) is busy (step S105), makes a normal incoming call instead of busy, When the facsimile communication procedure is executed by the call connection message transmission unit 11 and the call connection message reception unit 12, the image data of the original is read by the scanner unit 2 and necessary image processing, particularly by an encoding method corresponding to facsimile transmission. After the encoding, the image data (facsimile data) is transmitted to the called terminal Tb, which is the counterpart terminal, according to the communication procedure of the normal facsimile communication protocol, and the process is terminated.

  In step S105, when the counterpart terminal (calling terminal Tb) cannot respond due to busy or the like, the call connection message received from the called terminal Tb is received by the call connection message receiving unit 12, and the call connection message decoding unit is received. 9, it is checked whether or not a parameter (callback reception parameter: emergency transmission reception parameter) indicating “callback reception” is set (added) to the call connection message (step S107). If it is not set, it waits for a preset re-calling time and waits for a re-calling (step S108), and performs the same processing from step S101 as above (steps S103 to S108). In this case, the calling terminal Ta performs the re-call process for the preset number of re-calls, and stops the re-call process when the counterpart terminal does not respond in step S105.

  Then, as will be described later, the incoming call terminal Tb receives the incoming call by the call connection message receiving unit 12, decodes the call connection message by the call connection message decoding unit 9, and the callback response parameter is set in the call connection message. If so, the communication number management unit 14 is used to check whether the incoming call is possible. When the incoming call terminal Tb can answer the incoming call, the facsimile communication control unit 13 is used to start a normal facsimile reception protocol. When the incoming call terminal Tb cannot respond due to busy or the like, as shown in FIG. 4, the call connection message encoding unit 8 adds a callback acceptance parameter to the call connection message for disconnection, and the call ID generation unit 10 as shown in FIG. Then, a call ID (CallID) is generated and added, and the call connection message transmission unit 11 transmits a call connection message for disconnection to which the callback acceptance parameter and the call ID are added to the calling terminal Ta.

  If the callback acceptance parameter is set in the call connection message from the called terminal Tb, which is the counterpart terminal, in step S107, the calling terminal Ta reads the image data of the document by the scanner unit 2 and performs necessary image processing. Then, the image data is stored in the magnetic disk unit 6 (step S109), and the call ID is acquired from the callback reception parameter of the call connection message sent from the partner terminal, as shown in FIG. Is registered in the callback response reception management table (step S110). This callback response reception management table is stored in the magnetic disk unit 6 or an NVRAM (Nonvolatile Random Access Memory) (not shown) or the like, and as shown in FIG. 5, an IP address is registered as a destination and is associated with the IP address. Call ID (CallID) as call identification information is registered.

  When the calling terminal Ta stores the transmission document and the call ID, the calling terminal Ta stands by as a callback waiting state for waiting for a callback from the called terminal Tb (step S111).

  Then, the incoming call terminal Tb performs an emergency facsimile communication control process on the incoming call side as shown in FIG. That is, the called terminal Tb checks whether there is an incoming call (step S201), and if there is an incoming call, the communication number management unit 14 checks whether the terminal is ready for reception (step S202). If this is possible, the facsimile communication control unit 13 starts a normal facsimile reception protocol and performs normal facsimile reception processing (step S203).

  In step S202, when the own terminal cannot respond due to busy or the like, the code connection part 9 decodes the call connection message with the call connection message, and there is an emergency transmission designation in the call connection message, that is, a callback request parameter is added. If the callback request parameter is not added and the emergency transmission is not designated, a normal disconnect call connection message is transmitted from the call connection message transmitting unit 11 to the calling terminal Ta. The process ends (step S205).

  In step S204, if a callback request parameter is added to the call connection message and an emergency transmission is specified, a callback reception parameter (emergency transmission reception parameter) is added to the call connection message for disconnection, and a call ID (CallID) is set. Is added (step S206), and the call connection message transmitter 11 transmits the message to the calling terminal Ta (step S207).

  Upon receiving the call connection message for disconnection, the called terminal Tb registers the IP address of the calling terminal Ta in the callback destination of the callback request management table stored in the magnetic disk unit 6 or NVRAM (not shown). At the same time (step S208), the transmitted call ID (CallID) is registered in correspondence with the destination (IP address), and the state shifts to an emergency response standby state (callback response standby state) (step S209), and a call can be made. A check is made to see if the state is correct (step S210). This callback request management table has the same configuration as the callback response reception management table shown in FIG. 5, for example, and at least a callback destination and a call ID are registered.

  In step S210, when a call is ready in the emergency response standby state (callback response standby state), the called terminal Tb refers to the callback request management table and extracts the IP address from the callback destination ( Step S211), the call ID (CallID) registered corresponding to the IP address is extracted from the callback request management table, and the call connection message encoding unit 8 calls the call connection message as shown in FIG. A back response parameter is set (added), and a call ID (CallID) is set (step S212).

  The called terminal Tb generates a call connection message to which a parameter representing a callback response is added by the call connection message encoding unit 8, and transmits the call connection message from the call connection message transmission unit 11 to the calling terminal Ta (step S213).

  When the called terminal Tb transmits a call connection message to which a parameter indicating a callback response is added to the calling terminal Ta, the called terminal Tb checks whether the other party has responded (step S214).

  In step S214, when the calling terminal Ta that is the other party responds, the facsimile communication control unit 13 starts the facsimile reception protocol, receives the emergency image data requested for the callback, and ends the processing (step S215). ).

  Then, the calling terminal Ta in the callback waiting state (emergency transmission response waiting state) checks whether there is an incoming call (step S301) as shown in FIG. 8, and if there is an incoming call, it receives a call connection message. The call connection message is received by the unit 12, the received call connection message is decoded by the call connection message decoding unit 9, and the callback response parameter is set, that is, the call connection message is a call connection message for disconnection. It is checked whether a callback response parameter is added (step S302).

  When the callback response parameter is not set in step S302, the calling terminal Ta starts the normal facsimile reception protocol by the facsimile communication control unit 13 and performs normal facsimile reception (step S303).

  In step S302, when the callback response parameter is set in the call connection message, the calling terminal Ta confirms whether the call ID (CallID) added to the call connection message matches the call ID transmitted earlier. Whether or not the call ID is correct is checked (step S304).

  When the call ID is correct in step S304, the calling terminal Ta starts the facsimile transmission protocol by the facsimile communication control unit 13, reads the emergency image data previously stored in the magnetic disk unit 6 and sends it to the called terminal Tb. Facsimile transmission is performed (step S305).

  If the call ID is wrong in step S304, the calling terminal Ta disconnects the facsimile communication and ends the facsimile communication by the callback (step S306).

  As described above, in the facsimile apparatus 1 according to the present embodiment, as shown in the connection message sequence in FIG. 9, when the calling terminal Ta performs emergency transmission, the callback request and the call ID (Call ID) are set up in Setup. ) And is sent to the called terminal Tb. When the called terminal Tb sends Call Proceeding and the called terminal Tb cannot respond, the calling terminal Ta receives the callback reception and the call ID in the next Release Complete. (CallID) is added and sent to the calling terminal Ta to store the image data to be transmitted in the magnetic disk unit 6.

  After that, when the called terminal Tb becomes ready to make a call, in Setup, a callback response and a call ID (CallID) are added to the calling terminal Ta, and the calling terminal Ta sends the Call Proceeding and Connect procedures. Then, the image data stored in the magnetic disk unit 6 is transmitted from the calling terminal Ta to the called terminal Tb.

  The calling terminal Ta may manage the designation of emergency transmission in a table. That is, for example, when the calling terminal Ta performs a setting operation of the emergency transmission mode by designating the other party on the operation display unit (setting unit) 4, the CPU performs, for example, an emergency destination as illustrated in FIG. 10. A management table (emergency transmission necessity setting table) is created and stored in the magnetic disk unit 6 serving as an emergency transmission necessity setting table storage means, the NVRAM, or the like, and emergency transmission is performed by referring to the emergency destination management table. Check if the call request is specified. As shown in FIG. 10, the emergency destination management table is a table in which a destination (address) and emergency communication setting ON (ON) and OFF (OFF) are set.

  When the emergency transmission is managed by the emergency destination management table, the calling terminal Ta executes the emergency facsimile communication control process on the calling side shown in FIG. 2 as shown in FIG. In FIG. 11, the same step numbers are assigned to the same processing steps as in FIG. 2. In the description of FIG.

  That is, as shown in FIG. 11, the calling terminal Ta checks whether the CPU has made a call request during standby (step S101), and if there is a call request specifying the destination, the emergency destination shown in FIG. The management table is searched (step S121), and it is checked whether the call request is a call request for which emergency transmission is designated (step S122).

  When emergency transmission is not designated in step S122, the call connection message encoding unit 8 generates a normal call connection message and transmits it from the call connection message transmission unit 11 to the partner terminal Tb (step S103). If specified, the call connection message encoding unit 8 adds a callback request parameter that is an emergency transmission request parameter and a call ID (CallID) that is call identification information to the call connection message (step S104), and A call connection message to which the parameter is added is transmitted from the connection message transmission unit 11 (step S103).

  The calling terminal Ta executes the emergency facsimile communication calling process in the same manner as in FIG. 2 (steps S105 to S111).

  As described above, in this embodiment, the calling terminal Ta sends a message indicating that the incoming call terminal Tb is in a state incapable of facsimile communication in the outgoing call for transmitting the facsimile data instructed to perform the emergency transmission. Upon receipt, a callback request parameter that is an emergency transmission request parameter for requesting emergency transmission and a call ID that is call identification information for specifying a call requesting emergency transmission are added to the call connection message and transmitted. When a callback reception parameter, which is an emergency transmission reception parameter indicating that a callback request has been received from the called terminal Tb, and a call connection message to which the call ID is added are received, an emergency transmission is made in correspondence with the call ID. The target facsimile data (image data) is stored in the magnetic disk unit 6 to respond to an emergency transmission from the called terminal Tb. In the emergency transmission response standby state, a call connection message to which a callback response parameter and a call ID are added, which is an emergency transmission response parameter for responding to the emergency transmission request, is received in the emergency transmission response standby state. The facsimile data stored in the magnetic disk unit 6 is transmitted to the called terminal Tb, and the called terminal Tb receives the call connection message to which the callback request parameter and the call ID are added. When the facsimile data cannot be received, the callback acceptance parameter indicating that the callback request has been accepted and the call ID are added to the call connection message and transmitted to enter the emergency response standby state (callback response standby state). In the emergency response standby state, the facsimile communication ready state (callable state) is entered. When an emergency transmission response call is made by adding a callback response parameter and a call ID to a call connection message and transmitting the call request to the calling terminal Ta, the calling terminal Ta responds. Facsimile data is received from Ta.

  Therefore, it is possible to quickly and surely transmit image data that requires urgent reception when the receiving terminal Tb on the receiving side can receive the data, and the usability can be improved. For example, in the facsimile transmission of the order slip by facsimile communication between the product order receiving center and the branch office, even when the traffic is high, the facsimile transmission of the order slip can be performed reliably and promptly.

  Further, in this embodiment, when the emergency transmission is designated for the facsimile data or by designating the called terminal, the automatic operation is performed only when the called terminal Tb which is the called facsimile machine 1 cannot receive. In response to a callback transmission request, the called terminal Tb accepts the callback transmission, and when the facsimile reception is possible, the urgently designated facsimile data is transmitted by the callback from the called terminal Tb. ing.

  Therefore, only when the other party is busy cannot send a facsimile, there is no need to manually designate an emergency transmission and perform an emergency transmission process, and it is possible to reliably send emergency facsimile data with a unified operation. Usability can be improved.

  Furthermore, in the present embodiment, the calling terminal Ta registers the destination that requires emergency transmission and the on / off of the emergency transmission setting in the emergency destination management table and designates the destination for emergency transmission.

  Therefore, emergency transmission can be performed with a simple operation, and usability can be further improved.

  FIG. 12 shows emergency facsimile communication control processing at the time of incoming call on the calling side by the facsimile apparatus to which the second embodiment of the facsimile apparatus, facsimile communication system, facsimile communication control method, facsimile communication control program and recording medium of the present invention is applied. It is a flowchart to show.

  The present embodiment is applied to the facsimile apparatus 1 and the facsimile apparatus of the first embodiment. In the description of the present embodiment, the reference numerals used in the description of the first embodiment are used as necessary. This will be described as it is.

  In this embodiment, when an incoming call is received, the rejection of the incoming call is only due to the incoming call function such as no image data or a memory full (the capacity of the magnetic disk unit 6 storing the received image data in the memory reception is full). If there is, the incoming call is made without rejecting the incoming call for the call back response.

  That is, when an emergency transmission is designated, the calling terminal Ta transmits a call connection message with a callback request parameter for an emergency transmission request added as shown in FIG. Even when the terminal Tb is not able to perform facsimile transmission due to busy or the like, a call-back request is notified to the call-in terminal Tb, and a transition is made to an emergency transmission response wait state waiting for a call-back response from the call-in terminal Tb. Thus, emergency facsimile communication control processing at the time of an incoming call is performed.

  Then, as shown in FIG. 12, when there is an incoming call in the emergency transmission response standby state (step S401), the calling terminal Ta checks whether the incoming call response is possible by the communication number management unit 14 (step S402). If the call response is possible, the facsimile communication control unit 13 starts a normal facsimile reception protocol and performs normal facsimile reception processing (step S403).

  When the incoming call response cannot be made in step S402, the reception system error detection unit 7 detects whether or not the incoming call response cannot be made only for the incoming function such as no paper or memory full (step S404). If the reason why the incoming call cannot be answered is other reasons such as not limited to the incoming call function, the normal call connection message for disconnection is transmitted from the call connection message transmission unit 11 to the calling terminal Ta to perform the incoming call processing. The process ends (step S405).

  In step S404, the calling terminal Ta receives the call connection message for disconnection by the call connection message receiving unit 12 and decodes it by the code unit 9 using the call connection message when the reason why the incoming call cannot be answered is limited to the incoming call function. Then, it is checked whether or not the callback response parameter is set (step S406). When the callback response parameter is not set in the call connection message, a normal disconnect call connection message is sent from the call connection message transmission unit 11 The incoming call process is terminated by transmitting to the terminal Ta (step S407).

  When the callback response parameter is set in the call connection message in step S406, the calling terminal Ta matches the call ID (CallID) added in the call connection message parameter with the previously transmitted call ID. If the call ID is incorrect, a normal call connection message for disconnection is transmitted from the call connection message transmitter 11 to the calling terminal Ta, and the incoming call processing is terminated (step S408). S407).

  In step S408, when the call ID is correct, the calling terminal Ta starts the facsimile transmission protocol by the facsimile communication control unit 13, reads out the image data previously stored in the magnetic disk unit 6 and transmits it to the called terminal Tb by facsimile. (Step S409).

  As described above, when the calling terminal Ta of the present embodiment receives the call connection message to which the callback response parameter and the call ID are added from the called terminal Tb, the calling terminal Ta is in a state where communication of facsimile data is not possible. If there is a reason why the communication is impossible only in the receiving system that receives the facsimile data, the call is connected and responded, and the emergency transmission facsimile data stored in the magnetic disk unit 6 is sent to the called terminal Tb. Sending a fax to

  Therefore, when there is a reason that the facsimile communication is impossible only in the receiving system such as no paper or memory full, since the facsimile data transmission is not affected, the emergency facsimile data by the callback can be transmitted. Emergency transmission can be performed more reliably and promptly.

  FIG. 13 is a flowchart showing the emergency facsimile communication control process on the called side by the facsimile apparatus to which the third embodiment of the facsimile apparatus, facsimile communication system, facsimile communication control method, facsimile communication control program and recording medium of the present invention is applied. is there.

  The present embodiment is applied to the facsimile apparatus 1 and the facsimile apparatus of the first embodiment. In the description of the present embodiment, the reference numerals used in the description of the first embodiment are used as necessary. This will be described as it is.

  In the present embodiment, when the called terminal Tb sets and manages the callback response (emergency transmission response standby state) and the other terminal does not respond even if the callback response is made, FIG. As shown in FIG. 2, emergency facsimile communication incoming call processing for once canceling the callback response setting is performed. In FIG. 13, the same processing steps as those in FIG. 6 are given the same step numbers to simplify the description.

  That is, as shown in FIG. 13, the incoming call terminal Tb checks whether there is an incoming call (step S201), and if there is an incoming call, the communication number management unit 14 checks whether the own terminal is ready for reception. If it is possible to receive an incoming call (step S202), the facsimile communication control unit 13 starts a normal facsimile reception protocol and performs normal facsimile reception processing (step S203).

  In step S202, when the terminal cannot respond due to busy or the like, the code connection unit 9 decodes the call connection message with the call connection message, and whether or not the callback transmission request parameter is added to the call connection message, that is, emergency It is checked whether or not there is a transmission designation (step S204), and if no call request parameter is added to the call connection message and there is no emergency transmission designation, a normal call connection message for disconnection is sent from the call connection message transmission unit 11. It transmits to the calling terminal Ta and ends the processing (step S205).

  In step S204, if a callback request parameter is added to the call connection message and an emergency transmission is specified, a callback acceptance parameter is added to the call connection message for disconnection and a call ID (CallID) is added (step S204). (S206), the call connection message transmission unit 11 transmits the call to the calling terminal Ta (step S207).

  When the called terminal Tb transmits the call connection message for disconnection, it registers the IP address of the calling terminal Ta in the callback destination of the callback request management table provided in the magnetic disk unit 6 or NVRAM (not shown). At the same time (step S208), the transmitted call ID (CallID) is registered in correspondence with the destination (IP address), and the state shifts to the emergency transmission response waiting state (step S209). A check is made (step S210).

  When it becomes possible to make a call in the emergency transmission response standby state in step S210, the called terminal Tb refers to the callback request management table, extracts the IP address from the callback destination (step S211), and calls back the request. The call ID (CallID) registered corresponding to the IP address is extracted from the management table, and the call connection message encoding unit 8 sets a callback response parameter in the call connection message, and sets the call ID (CallID). Set (step S212).

  The called terminal Tb adds the callback response parameter and the call ID to the call connection message, and transmits the call connection message from the call connection message transmission unit 11 to the calling terminal Ta (step S213).

  When the called terminal Tb transmits a call connection message to which the callback response parameter and the call ID are added to the calling terminal Ta, the called terminal Tb checks whether the other party does not have a facsimile communication function or the other party does not respond (step). S501) When the calling terminal Ta as the other party responds, the facsimile communication control unit 13 starts the facsimile reception protocol, receives the emergency image data requested for the callback, and ends the processing (step S215). .

  In step S501, when the other party does not have a facsimile communication function or does not respond in step S501, the called terminal Tb cancels the call by the callback response, and also receives the callback destination and the call ID from the callback response reception management table. Is deleted (step S502).

  As described above, the incoming call terminal Tb of the present embodiment temporarily cancels the callback response waiting state when the call terminal Ta cannot start facsimile communication due to busy or the like when the call is made by the callback response. It is possible to prevent a complicated communication standby state from being continued forever and improve the usability.

  FIG. 14 is a flowchart showing emergency facsimile communication control processing on the called side by the facsimile apparatus to which the fourth embodiment of the facsimile apparatus, facsimile communication system, facsimile communication control method, facsimile communication control program and recording medium of the present invention is applied. is there.

  The present embodiment is applied to the facsimile apparatus 1 and the facsimile apparatus of the first embodiment. In the description of the present embodiment, the reference numerals used in the description of the first embodiment are used as necessary. This will be described as it is.

  In the present embodiment, when the calling terminal Tb does not respond due to busy even if the calling terminal Tb does not respond due to busy in the state where the calling terminal Tb sets and manages the callback response, as shown in FIG. An emergency facsimile communication control process is performed for re-calling a callback response after a predetermined re-call time interval. In FIG. 14, the same processing steps as those in FIG. 6 are assigned the same step numbers to simplify the description.

  That is, as shown in FIG. 14, the incoming call terminal Tb checks whether there is an incoming call (step S201), and if there is an incoming call, the communication number management unit 14 checks whether the terminal is ready for reception. If it is possible to receive an incoming call (step S202), the facsimile communication control unit 13 starts a normal facsimile reception protocol and performs normal facsimile reception processing (step S203).

  In step S202, when the terminal cannot respond due to busy or the like, the code connection unit 9 decodes the call connection message with the call connection message, and whether or not a callback request parameter is added to the call connection message, that is, emergency transmission. Whether or not there is designation is checked (step S204), and when there is no emergency transmission designation, a normal call connection message for disconnection is transmitted from the call connection message transmission unit 11 to the calling terminal Ta and the processing is terminated (step S205).

  In step S204, if a callback request parameter is added to the call connection message and an emergency transmission is specified, a callback acceptance parameter is added to the call connection message for disconnection and a call ID (CallID) is added (step S204). (S206), the call connection message transmission unit 11 transmits the call to the calling terminal Ta (step S207).

  When the called terminal Tb transmits the call connection message for disconnection, it registers the IP address of the calling terminal Ta in the callback destination of the callback request management table provided in the magnetic disk unit 6 or NVRAM (not shown). At the same time (step S208), the transmitted call ID (CallID) is registered in correspondence with the destination (IP address), and the state shifts to the emergency response waiting state (step S209), and it is checked whether the call can be made. (Step S210).

  In step S210, when it becomes possible to make a call, the called terminal Tb refers to the callback request management table, extracts the IP address from the callback destination (step S211), and extracts the IP address from the callback request management table. The call ID (CallID) registered corresponding to the call ID is extracted, and the call connection message encoding unit 8 sets the callback response parameter in the call connection message and sets the call ID (CallID) (step S212). .

  The called terminal Tb adds the callback response parameter and the call ID to the call connection message, and transmits the call connection message from the call connection message transmission unit 11 to the calling terminal Ta (step S213).

  When the called terminal Tb transmits a call connection message to which the callback response parameter and the call ID are added to the calling terminal Ta, the called terminal Tb checks whether or not the other party is busy and responds (step S601). When Ta responds, the facsimile communication control unit 13 starts the facsimile reception protocol, receives the urgent image data requested for the callback, and ends the processing (step S215).

  In step S601, when the other party is not busy and responds, the called terminal Tb interrupts the call by the callback response and waits for a preset re-call time (step S602), and then proceeds to step S210. Returning, it is checked whether or not the call can be made (step S210).

  If a re-call is possible in step S210, the callback destination IP address is extracted from the callback response management table, and the call ID is acquired and set in the call connection message (steps S212 and S213). From the process of setting the callback response parameter and the call ID and transmitting to the calling terminal Ta, the same process as described above is performed (steps S210 to S213, S215, S601, and S602).

  In this way, even if the called terminal Tb of the present embodiment makes a call by a callback response, but the other calling terminal Ta does not respond by busy, it waits for a predetermined re-calling time and calls back again. Calls based on responses can be continuously made, emergency data can be transmitted more reliably, and usability can be improved.

  15 and 16 are diagrams showing a fifth embodiment of a facsimile apparatus, a facsimile communication system, a facsimile communication control method, a facsimile communication control program, and a recording medium of the present invention. FIG. 15 shows a facsimile apparatus of the present invention, FIG. 16 shows an example of a callback response reception wait management table stored in a facsimile apparatus to which a fifth embodiment of a facsimile communication system, a facsimile communication control method, a facsimile communication control program, and a recording medium is applied. It is a flowchart which shows the emergency facsimile communication control processing by a terminal.

  The present embodiment is applied to the facsimile apparatus 1 and the facsimile apparatus of the first embodiment. In the description of the present embodiment, the reference numerals used in the description of the first embodiment are used as necessary. This will be described as it is.

  In the present embodiment, when the calling terminal Ta makes a callback request, an emergency facsimile communication control process for managing the callback response reception and releasing the waiting for the callback response is performed after a preset callback waiting time elapses. .

  That is, as shown in FIG. 2, the calling terminal Ta makes a call by setting the callback request parameter for emergency transmission request and the call ID in the call connection message in accordance with the designation of emergency transmission, and calls the called terminal Tb. If the call does not respond, the IP address of the called terminal Tb is associated with this IP address in the destination column of the callback response reception waiting management table as shown in FIG. Is registered, and a callback waiting time which is a waiting time for calling back a response from the called terminal Tb which is the destination is set and registered. When the calling terminal Ta registers in the callback reception waiting management table, the calling terminal Ta enters an emergency transmission response standby state (callback response incoming call waiting state), and performs an emergency facsimile communication control process shown in FIG. In FIG. 16, the same step number is assigned to the same processing step as the emergency facsimile communication process at the time of incoming call on the calling side in FIG.

  Then, as shown in FIG. 16, the calling terminal Ta checks whether there is an incoming call (step S301), and when there is an incoming call, the call connection message receiving unit 12 receives and receives the call connection message. The call connection message is decoded by the call connection message decoding unit 9 to check whether the callback response parameter is set, that is, whether the call connection message is a call connection message for disconnection and a callback response parameter is added ( Step S302).

  When the callback response parameter is not set in step S302, the calling terminal Ta starts the normal facsimile reception protocol by the facsimile communication control unit 13 and performs normal facsimile reception (step S303).

  When the callback response parameter is set in the call connection message in step S302, the calling terminal Ta sets the call ID (Call ID) added to the call connection message to wait for reception of the callback response shown in FIG. Whether or not the call ID is correct is checked based on whether or not it matches the call ID registered for the destination IP address in the management table (step S304).

  If the call ID is wrong in step S304, the calling terminal Ta disconnects the facsimile communication and ends the facsimile communication by the callback (step S306).

  In step S304, when the call ID is correct, the calling terminal Ta is within the callback waiting time (time limit) registered for the IP address of the called party in the callback response reception waiting management table. That is, after making a call for a callback request to the called terminal Tb first, it is checked whether the incoming call is within the callback waiting time (step S701), and the incoming call is within the callback waiting time. Then, the facsimile transmission protocol is started by the facsimile communication control unit 13, the image data previously stored in the magnetic disk unit 6 is read and transmitted to the called terminal Tb by facsimile (step S305).

  In step S701, the calling terminal Ta disconnects the facsimile communication and terminates the facsimile communication by the callback if the incoming call has passed the callback waiting time (step S306).

  As described above, the calling terminal Ta of the present embodiment cancels the callback waiting state when the callback response from the called terminal Tb is not within the predetermined callback waiting time after making the callback request. Thus, when urgent data is transmitted by other methods, the urgent data stored in the magnetic disk unit 6 can be deleted, and the callback waiting state can be prevented from being continued, thereby improving the usability. be able to.

  The invention made by the present inventor has been specifically described based on the preferred embodiments. However, the present invention is not limited to that described in the above embodiments, and various modifications can be made without departing from the scope of the invention. It goes without saying that it is possible.

  The present invention can be used for a facsimile apparatus, a facsimile system, a facsimile communication control method, a facsimile communication control program, and a recording medium that transmit and receive emergency image data by facsimile.
