Description

  The present invention creates a transmission file to be transmitted to a receiver terminal by performing transmission file creation processing on the received file received from the sender terminal in parallel, and transmits the created transmission file to the receiver terminal. The present invention relates to a file mediation program, a file mediation device, and a file mediation method that mediate file transmission / reception.

  2. Description of the Related Art Conventionally, a file intermediary system that supports transmission and reception of electronic data such as slips between a sender terminal and a receiver terminal when performing an inter-company electronic commerce is known (for example, see Patent Document 1). Specifically, the received file received from the sender terminal is queued in a single queue and the "send file creation process" is performed, and the send file subjected to this "send file creation process" is sent to the receiver terminal. It transmits sequentially.

  That is, in this file mediation system, a header added to a received file received from a sender terminal in order to effectively mediate file exchange between the sender terminal and the receiver terminal as an interface for inter-company electronic commerce. Based on the information, the “splitting process” that divides the received file for each destination included in the header information and the compatibility of the file formats handled by the sender terminal and the receiver terminal respectively. “Transmission file creation processing” such as “conversion processing” for converting the file format of the received file received from the terminal into the file format handled by the recipient terminal is performed.

  However, since this “transmission file creation process” is a process with a heavy processing load, it naturally takes a long processing time. For this reason, if the configuration in which the received file is queued with a single queue and the “transmission file creation process” is performed is adopted, the throughput related to the “transmission file creation process” is reduced.

  For this reason, in recent years, file mediation systems have been developed in which received files received from a sender terminal are queued in a plurality of queues and “transmission file creation processing” is performed in parallel.

  According to this conventional technique, the received file received from the sender terminal is queued in a plurality of queues, and the “transmission file creation process” is performed in parallel, thereby improving the throughput related to the “transmission file creation process”. be able to.

  However, the above prior art cannot evaluate the validity of the transmission order of transmission files (whether or not the transmission order of transmission files is the same as the reception order). Even if the transmission file creation completion order is different from the original reception order, the situation where the transmission file is transmitted in a different order from the reception order is overlooked. It was.

  This will be explained with a specific example. When a reception slip relating to “cancel” of this order is received after receiving a reception slip relating to “order” from the sender terminal, the reception order is as follows. It is necessary to transmit these transmission slips to the receiver terminal in the order of the slip relating to “ordering” and the slip relating to “cancellation”.

  However, in the above-described prior art, it is impossible to evaluate the situation that the creation completion order of the transmission slip is different from the reception order and the validity of the transmission order of the transmission slip. This is a case where the processing load of “transmission file creation processing” for the received file queued before the voucher related to is heavy and the transmission voucher related to “cancel” is created before the transmission voucher related to “order”. However, the slip relating to the “order” will be left behind and the slip relating to the “cancellation” will be transmitted to the receiver terminal, resulting in confusion in the transaction between the sender and the receiver. .

  Therefore, the present invention has been made to solve the above-described problems (problems) of the prior art, and the transmission file creation processing (for example, division processing and conversion processing) for the received file is performed in parallel while being transmitted.

  Exemplary embodiments of a file mediating apparatus according to the present invention will be described below in detail with reference to the accompanying drawings. In the following, after describing the outline and features of the file mediation system according to the present invention, the file mediation system according to the first embodiment will be described. Finally, various modifications (example 2) will be described as other embodiments. ) Will be explained.

(Overview and features)
First, the outline and features of the file mediation system according to the present invention will be described. FIG. 1 is a block diagram illustrating the configuration of the file mediation system according to the first embodiment. As shown in the figure, the file intermediary system 1 is connected to sender terminals 50-1, 50-2,... 50-n (hereinafter referred to as sender terminals 50 as appropriate) via the Internet 2. And receiver terminals 60-1, 60-2... 60 -n (hereinafter referred to as receiver terminals 60 as appropriate) so as to be able to communicate with each other.

  Among these, the sender terminal 50 transmits a predetermined file (that is, electronic data such as a slip) to the desired receiver terminals 60-1, 60-2... 60-n via the file mediation system 1. The receiver terminal 60 is a terminal device that receives a predetermined file transmitted from the sender terminals 50-1, 50-2... 50-n via the file mediation system 1. .

  Here, the file mediation system 1 according to the present invention adds a sequence number to the received file in accordance with the reception order of the received file received from the sender terminal 50, the sequence number of the added received file, and the received file The “transmission file creation process” completion status of the file is stored in association, and the transmission file creation source is created based on the “transmission file creation process” completion status of the stored received file. Check whether the transmission file creation process is completed for the received file with a number smaller than the sequence number of the received file, determine whether the transmission file can be transmitted, and determine the transmission file that is determined to be transmittable. The main feature is that the sequence numbers are sent in order. Shin file creation processing (e.g., dividing such processing and conversion) while parallelize, so that it is possible to transmit the transmission file as the reception order.

  This main feature will be described in detail. The file mediation system 1 is configured so that the transmission file creation completion order is replaced with the original reception order due to the parallelization of the “transmission file creation process”. The sequence numbers are added to the received files in ascending order according to the reception order of the received files received from the sender terminal 50 so that the transmission order of the transmission files can be sorted according to the reception order. Further, in order to monitor the transmission file created from the received file received after the transmission file created from the received file received earlier is sent, the sequence number of the received file and the “ Whether or not the “send file creation process” can be completed (that is, “unprocessed” or “processed”) is stored in association with each other.

  Then, the file mediation system 1 receives the received file to which a number smaller than the sequence number of the received file that is the transmission file creation source is added based on the completion status of the “transmitted file creation process” for the received file. By checking whether or not the "send file creation process" can be completed, send files that should not be sent at present (that is, send files created earlier than received files received earlier at this time) and can be sent now So that it can be distinguished from an outgoing file.

  Therefore, in the above-mentioned example of the prior art, the situation where the transmission file is transmitted in an order different from the reception order due to the parallelization of the “transmission file creation process” is not overlooked. Monitor the transmission file created from the received file received after the transmission file created from the received file received earlier, and send the current file and the transmission file that should not be transmitted at present Differentiated from the transmission file, and among the transmission files that can be transmitted at present, the transmission order of the transmission file is sorted according to the reception order. Send files can be sent in the order of reception while parallelizing (for example, split processing and conversion processing) It made.

  Next, the file mediation system according to the first embodiment will be described. FIG. 1 is a block diagram illustrating the configuration of the file mediation system according to the first embodiment. As shown in the figure, the file mediation system 1 includes a reception server 10, a storage server 20, a transmission file creation server 30, and a transmission server 40. In the following, the function of each server that constitutes the file mediation system 1 will be described, and the processing operation of each server will be described together with the function using sequential flowcharts.

  Among these, the receiving server 10 is a server device that receives a predetermined file (that is, electronic data such as a slip) from the sender terminals 50-1, 50-2,... 50-n, and is closely related to the present invention. A sequence number adding unit 10a is provided as a related functional unit.

  The sequence number adding unit 10a is a processing unit that adds sequence numbers to the received file in ascending order according to the reception order of the received file received from the sender terminal 50. Specifically, a time stamp is added as a sequence number to the received file received from the sender terminal 50.

  At this time, when a plurality of received files are received at the same time, a correction value (for example, “α” = “1 minute”) corresponding to the number of simultaneously received files is added to the reception time of each received file simultaneously. To. For example, when three received files are received at time “10:01”, nothing is added to the reception time of the first received file, and the correction value “ 1 minute ”is added, and the correction value“ 2 minutes ”is added to the reception time of the third received file.

  Thus, by adding a time stamp as a sequence number to the received file received from the sender terminal 50, an appropriate sequence number can be added with a simple configuration.

(Receiving server processing procedure)
Here, the processing procedure of the receiving server 10 will be described. FIG. 2 is a flowchart showing the processing procedure of the receiving server 10. As shown in the figure, when the receiving server 10 receives a received file from the sender terminal 50 (Yes at step S201), the receiving server 10 stores the received file in the received file DB 21 (step S202).

  Then, as shown in FIG. 3, the sequence number adding unit 10a sets the processing status flag (completion status) of the received file in the processing status management table 22 to “unprocessed” (step S203) and the sender A time stamp is added as a sequence number to the received file received from the terminal 50 (step S204).

  In this way, the receiving server 10 recursively performs the processes of steps S201 to S204, and receives the received file from the sender terminal 50.

  Returning to the description of FIG. 1, the storage server 20 is storage means (storage means) that stores data and programs necessary for various processes performed by each server (that is, the reception server 10, the transmission file creation server 30, and the transmission server 40). There are a reception file 21, a processing state management table 22, a transmission file DB 23, and a transmission state management table 24, which are closely related to the present invention.

  Among these, the received file DB 21 is a database that stores received files received from the sender terminal 50. The processing state management table 22 is a table for managing the processing state of the transmission file creation processing for the received file. For example, as shown in FIG. 3, the received file sequence number “10:01” and the received file Is stored in association with the processing status flag (completion status) “unprocessed” of the transmission file creation processing for

  The transmission file DB 23 is a database that stores transmission files created by the transmission file creation server 30. The transmission status management table 24 is a table for managing the transmission availability status of each transmission file in association with each transmission file. For example, as illustrated in FIG. 6, the transmission status management table 24 transmits to the transmission file “File 2′-1”. The availability status flag “transmission impossible” is stored in association with each other.

  The transmission file creation server 30 is a server device that performs transmission file creation processing on the received file received from the sender terminal 50, and includes a division processing unit 31 and a conversion processing unit 32 as functional units related to the present invention. Among them, the division processing unit 31 is a processing unit that divides the received file for each destination included in the header information based on the header information added to the received file received from the sender terminal 50, and performs conversion processing. The unit 32 is a processing unit that converts the file format of the received file received from the sender terminal 50 into a file format handled by the recipient receiver terminal 60.

  As described above, by having a plurality of transmission file creation servers that perform the “transmission file creation processing” on the received file received from the sender terminal 50, the “transmission file creation processing” can be performed within one apparatus. Compared to parallel execution, “send file creation processing” can be performed with higher specifications, and the performance of the file mediation system can be improved.

  Here, the processing procedure of the transmission file creation server 30 will be described. FIG. 4 is a flowchart showing a processing procedure of the transmission server creation server 30. This processing is performed for each received file whose processing status flag in the processing status management table 22 is “unprocessed” by each of the transmission file creation servers 30 (that is, the transmission file creation servers 30-1, 30-2... 30-n). Is started by sequentially searching. Here, the transmission file creation server 30-2 will be described as an example.

  As shown in the figure, when the search process of the received file whose processing status flag is “unprocessed” performed by another transmission file creation server 30 is completed (Yes in step S401), the transmission file creation server 30-2. Searches the processing status management table 22 for a received file whose processing status flag is “unprocessed” (step S402).

  Then, when there is a received file whose processing state flag is “unprocessed” (Yes in step S403), the received file “File 2” whose processing state flag is “unprocessed” is read from the received file DB 21 (step S404). ).

  Subsequently, the division processing unit 31-2 in the transmission file creation server 30-2 divides the file for each destination (transmission destination) included in the header information based on the header information added to the received file ( In step S405), information (for example, file number and sequence number) of the division source received file is added to each of the divided messages (files), and these messages (files) are converted into conversion processing units 32a-2 and 32b-. 2 (step S406).

  For example, in the example shown in FIG. 3, the division processing unit 31-2 in the transmission file creation server 30-2 receives the destination (that is, “A → C”, “A → D”) included in the header information of the received file. ) For each message whose destination is “A → C”, and the message whose destination is “A → D” is converted to the conversion processor 32a-2. It distributes to the part 32b-2.

  Then, the conversion processing units 32a-2 and 32b-2 convert the divided message into a transmission file (Step SA407 and Step SB407), and store the converted transmission file in the transmission file DB 23 (Step SA408 and Step SB408). ). Specifically, as shown in FIG. 3, the file format of the received file received from the sender terminal 50-1 (Company A) is changed to the recipient terminal 60-1 or 60-2 (Company C or Company D). The transmission file is created by converting into the file format handled in (1), and the created transmission file is stored in the transmission file DB 24.

  Here, when the conversion of all the divided messages (for example, the message distributed to the conversion processing unit 32a-2 and the message distributed to the conversion processing unit 32b-2) is completed (Yes in step S409), the transmission is performed. The file creation server 30-2 updates the processing status flag of the received file “File 2”, which is the creation source of each transmission file, in the processing status management table 22 to “processed” (step S410).

  Then, as shown in FIG. 6, the transmission file creation processing unit 30-2 determines whether each transmission file (that is, “File 2′-1” and “File 2′-2”) can be transmitted in the transmission state management table 24. The status flag is set to “transmission impossible” (step S411).

  In this way, the transmission file creation server 30 recursively performs the processing of the above steps S401 to S404, performs the transmission file creation processing in parallel with the reception file received from the sender terminal 50, and receives the recipient. A transmission file to be transmitted to the terminal 60 is created.

  Returning to the description of FIG. 1, the transmission server 40 is a server device that transmits the transmission file created by the transmission file creation server 30 to the receiver terminal 60, and as a function unit closely related to the present invention, the transmission permission / inhibition determination is performed. Unit 40a and transmission processing unit 40b.

  Among these, the transmission permission / inhibition determination unit 40a has a number smaller than the sequence number of the reception file from which the transmission file is created for the transmission file in which the transmission permission / non-transmission status flag “transmission disabled” is held by the transmission state management table 24 When the “transmission file creation process” for the received file to which “” is added has been completed, the transmission availability flag of the transmission file is updated to “transmission possible”.

  In addition, when the reception file is divided into a plurality of destination transmission files by the transmission file creation process, the transmission permission / inhibition determination unit 40a receives the reception file that is a creation source of each transmission file divided for each of the plurality of destinations. The transmission file creation process for the received file to which a number smaller than the sequence number is added is checked to determine whether the transmission file divided for each of the plurality of destinations can be transmitted.

  More specifically, in the example of FIG. 6, the division processing unit 31-2 receives the transmission file having a plurality of destinations (that is, the transmission file “File 2′-1” whose destination is “A → C”, And each of the divided transmission files (“File 2′-1” and “File 2′-2”) are divided into transmission files “File 2′-2” whose destination is “A → D”. It is determined whether or not the transmission file creation processing for the received file to which a number smaller than the sequence number “10:02” of the received file “File 2” that is the creation source is completed is completed. In this example, both “File 2′-1” and “File 2′-2” have “File 1” with a time stamp (10:01) earlier than the time stamp (10:02) of the creation source file “File 2”. Therefore, it is determined that “transmission is impossible”.

  In this way, when the received file is divided into a plurality of destination transmission files by the transmission file creation processing, the sequence number of the reception file that is the creation source of each transmission file divided for each of the plurality of destinations. By checking whether or not the transmission file creation process for the received file with a smaller number is completed and determining whether or not the transmission file divided for each of the multiple destinations can be transmitted, Even when the transmission file is divided, it is possible to accurately determine whether each transmission file can be transmitted.

  Here, the processing procedure of the transmission permission / inhibition determination unit 40a will be described. FIG. 5 is a flowchart illustrating a processing procedure of the transmission permission / inhibition determination unit 40a. As shown in the figure, the transmission permission / inhibition determination unit 40a searches the transmission state management table 24 for a transmission file whose transmission permission / inhibition state flag is “transmission disabled” (step S501).

  Then, when there is a transmission file whose transmission permission / non-permission status flag is “transmission disabled” (Yes in step S502), the transmission permission / non-permission determination unit 40a sets the transmission file creation source whose transmission permission / non-transmission status flag is “transmission disabled” The received file information (sequence number) is sequentially read from the processing state management table 22 (step S503).

  Here, the transmission permission / inhibition determination unit 40a receives the processing status flag (end) of the received file whose reception time is earlier than the time stamp (sequence number) of the received file that is the creation source of the transmission file and that is received from the same sender terminal. It is checked whether or not there is a received file whose availability status is “unprocessed” (step S504).

  If there is no received file that satisfies the determination condition (No at Step S505), the transmission permission determination unit 40a holds that the transmission permission flag of the transmission file should be changed to “transmission enabled”. (Step S506). For example, in the example of FIG. 7, there is no received file that is earlier than the time stamp of the source file “File 1” of the transmission file “File 1 ′” and received from the same sender terminal 50-1 (Company A). Therefore, it holds that the transmission availability flag of the transmission file “File 1′-1” should be changed to “transmission enabled”.

  On the other hand, if there is a received file that satisfies the determination condition (Yes in step S505), the transmission permission determination unit 40a holds that the transmission permission flag of the transmission file should be changed to “transmission disabled”. (Step S507). For example, in the example of FIG. 6, there is a received file “File 1” whose time stamp is earlier than the creation source file “File 2” of the transmission file “File 2′-1” and whose processing status flag is “unprocessed”. Therefore, it holds that the transmission permission / non-permission status flag of the transmission file “File 2′-1” should be changed to “transmission impossible”.

  Then, the transmission permission / non-permission determination unit 40a performs the “transmission permission / non-transmission determination” in steps S503 to S507 described above until the “transmission permission determination processing” is completed for all transmission files whose transmission permission / non-permission status flag is “transmission impossible” (step S508 affirmative). Continue the “judgment process”.

  Thereafter, the transmission permission / inhibition determination unit 40a completes the “transmission permission / inhibition determination process” for all the transmission files whose transmission permission / inhibition status flag is “transmission disabled” (Yes in step S508), and stores each of the files held in steps S506 and S507. The transmission availability flag of the transmission file is updated at the same time (step S509).

  As described above, the “transmission file creation process” is completed for a reception file to which a number smaller than the sequence number of the reception file that is the creation source of the transmission file is added and the reception file received from the same sender terminal Since it is decided to check whether or not the transmission is possible, transmission files of different transmission sources that do not need to compensate for the transmission order can be excluded from the objects to be checked, and file transfer can be effectively mediated.

  Returning to the description of FIG. 1, the transmission processing unit 40 b is a processing unit that transmits transmission files determined to be transmittable by the transmission permission determination unit 40 b in the order of sequence numbers. Specifically, the transmission state management table The transmission files having the transmission permission / non-permission status flag of “transmission enabled” are sorted in the order of the sequence numbers, and the sorted transmission files are sequentially transmitted to the receiver terminal 60.

  Here, a processing procedure of the transmission processing unit 40b will be described. FIG. 8 is a flowchart illustrating a processing procedure of the transmission processing unit 40b. As shown in the figure, the transmission processing unit 40b searches the transmission status management table 24 for a transmission file whose transmission permission / non-permission status flag is “transmission enabled” (step S801).

  Subsequently, when there is a transmission file whose transmission permission / non-permission status flag is “transmission enabled” (Yes in step S802), the transmission processing unit 40b transmits a transmission file whose transmission permission / non-transmission status flag is “transmission enabled” to the transmission file DB 23. (Step S803).

  Then, as shown in FIG. 7, the transmission processing unit 40b sets the transmission file read from the transmission file DB in the order of the time stamp of the reception file that is the creation source (ie, “File 0 ′” (10:00), “File”). 1 ′ ”(10:01),“ File 2′-1 ”(10:02),“ File 2′-2 ”(10:02) in this order) (step S804), and the sorted transmission file Are sequentially transmitted to the receiver terminal 60 (step S805).

  As described above, according to the file mediation system 1 according to the first embodiment, for each transmission file, the transmission availability state of the transmission file is stored in association with each other, and the transmission impossible state of the transmission file stored as the transmission impossible state is stored. When the transmission file creation process for a received file with a number smaller than the sequence number of the received file that is the creation source has been completed, the transmission availability status of the transmission file is updated to the transmission enabled status, and the transmission enabled status The transmission file stored in the sequence number is transmitted in the order of sequence numbers, so that the transmission availability status of the transmission file can be managed more effectively, and the “transmission file creation process” (for example, the division process and the Conversion files, etc.) can be parallelized more effectively, and transmission files can be transmitted in the order of reception. .

  Although the embodiments of the present invention have been described so far, the present invention can be implemented in various different embodiments in addition to the above-described first embodiment within the scope of the technical idea described in the claims. It may be. Therefore, as shown below, different embodiments will be described by dividing into (1) configuration, (2) transmission permission / inhibition determination, (3) others, and the like.

(1) Configuration For example, in Example 1, as shown in FIG. 1, “Company A”, “Company B”... “Company X” are used as sender terminals, and “Company C”, “Company D” ··· An example in which “Company Y” is a receiver terminal has been described, but the present invention is not limited to this, and “Company A”, “Company B”, “Company C”, “Company D”, “Company X” and “Company Y” may each be a sender terminal or a receiver terminal.

  In the first embodiment, “division processing” and “conversion processing” are performed as “transmission file creation processing” performed by the transmission file creation server 30, but the present invention is not limited to this. Both of these may be performed, or any one of them may be performed.

(2) Judgment of transmission possibility For example, in the first embodiment, after the “transmission file creation process” is performed, the destination information of the transmission file divided by the division processing unit 31 is updated to the processing state management table 22. However, the present invention is not limited to this, and when the reception file is divided into a plurality of destination transmission files by the division processing unit 31 (time point), each transmission file divided from the reception file is The destination information may be stored.

  Specifically, as shown in FIG. 9, the division processing unit 31-2 converts the received file “File 2” into transmission files of a plurality of destinations (“A → C” and “A → D”). At the time of division, the destination information (“A → C” and “A → D”) of each transmission file divided from the received file “File 2” is written in the processing state management table 22.

  Then, the transmission permission / inhibition determination unit 40a processes the processing state flag (end permission / non-permission state) of the “transmission file creation process” for the reception file stored by the processing state management table 22, and the destination of each transmission file divided from the reception file. Based on the information, the received file to which a number (10:01) smaller than the sequence number (10:02) of the received file “File 2” that is the creation source of the transmission file “File 2′-2” is added Whether the “transmission file creation process” for “File 1” has been completed, and the transmission source (Company A) and the transmission destination in the received file “File 1” for which “transmission file creation process” has not been completed. It is checked whether or not there are received files having the same (Company D), and it is determined whether or not the transmission file can be transmitted (see FIG. 10).

  As shown in FIG. 10, there is no reception file whose transmission destination is not determined among the reception files received before the creation file “File 2” of the transmission file “File 2′-2”, and the same transmission is performed. Since there is no received file whose processing status flag is “unprocessed” with respect to the previous received file, the transmission enable / disable status flag in the transmission status management table 22 is updated to “transmittable”.

  As described above, when the received file is divided into a plurality of destination transmission files by the transmission file creation processing, the destination information of each transmission file divided from the reception file is further stored, and the transmission file creation for the reception file is performed. Transmission to a received file to which a number smaller than the sequence number of the received file that is the source of the transmission file is added based on whether processing is completed or not and destination information of each transmission file divided from the received file Check whether the file creation process has been completed and whether there is a received file with the same source and destination in the received file for which the transmission file creation process has not been completed. Since it was decided to determine whether or not the file can be sent, different destinations that do not need to compensate the transmission order Can exclude a transmission file from Shosa subject, it is possible to effectively mediate exchange of files.

  In the first embodiment, the processing state management table 22 stores one processing state flag (end / non-completion state) for one received file. However, the present invention is not limited to this. If the received file is divided into a plurality of destination transmission files by “transmission file creation processing”, “transmission file creation processing” for the received file for each destination of each transmission file divided from the reception file. May be stored. (Processing end flag)

  For example, as shown in FIG. 11, the file division server 31-2 divides the received file “File 2” into transmission files of a plurality of destinations (“A → C” and “A → D”), respectively. For each destination information (“A → C” and “A → D”) of each transmission file divided from the received file “File 2”, a processing status flag (completion status) “unprocessed” is stored in the processing status management table 22. Write. At this time, the processing state management table 22 stores the sequence number of the received file and the division processing end possibility state in association with each other, and also associates the destination information of the divided transmission file with the conversion processing end state. It will be memorized.

  Then, as shown in FIG. 12, when the configuration of the information in the processing state management table 22 and the transmission state management table 24 is changed, the transmission permission / inhibition determination unit 40a creates the creation source file “File 2′-2” Among the received files received before “File 2”, there is no received file whose division is “unprocessed”, and a message with the same destination and conversion of “unprocessed” is included in the divided messages. Therefore, the transmission enable / disable state flag in the transmission state management table 22 is updated to “transmission enabled”.

  As described above, when the received file is divided into a plurality of destination transmission files by the “transmission file creation processing”, the “transmission file creation” is performed on the received file for each destination of each transmission file divided from the reception file. By storing the processing status flag (completion status) of “Processing”, it is possible to exclude transmission files of different transmission destinations that do not need to compensate for the transmission order, and effectively mediate file exchange It becomes possible.

  Further, in the first embodiment, the embodiment in which the present invention is applied when the received file is divided into a plurality of destination transmission files by the division processing has been described, but the present invention is not limited to this, The same applies to the case where the received file is divided into a plurality of (same destination) transmission files by the division processing.

  That is, when the division processing unit 31-2 divides the received file “File 5” into a plurality of transmission files (all destinations are “A → C”), the transmission permission / inhibition determination unit 40a A number (10) smaller than the sequence number (10:00) of the received file “File 5” from which the transmission files “File 5′-1”, “File 5′-2” and “File 5′-3” are created. : 08) is added to the received file “File 4” to determine whether or not the transmission file creation process is completed, and it is determined whether or not the divided transmission file can be transmitted. At this time, the files divided by the division processing unit 31-2 are not distributed to the conversion processing units 32a-2, 32b-2, and 32c-2, and are not processed. Input serially.

  In this case, since there is no received file that is earlier than the time stamp (10:00) of the source file “File 5” of the transmission file “File 5′-1” and received from the same sender terminal, the transmission state management is performed. The transmission enable / disable state flag in the table 22 is updated to “transmission enabled”.

  In this way, when a received file is divided into a plurality of transmission files by the transmission file creation process, a reception file to which a number smaller than the sequence number of the reception file from which the divided transmission files are created is added. Whether or not the transmission file creation process for the file is completed and whether or not the transmission file after division is determined can be transmitted or not. Even if the reception file is divided into multiple transmission files by the division process, whether or not each transmission file can be transmitted Judgment can be made accurately.

  In the present invention, the transmission permission / inhibition determination unit 40a is a reception file to which a number smaller than the sequence number of the reception file that is the creation source of the transmission file is added, and the reception file received from the same sender terminal It is also possible to check whether or not the transmission file creation process for the received file of the same file type is complete. In other words, this makes it possible to exclude transmission files that are different types of files that do not need to compensate for the transmission order, and effectively mediate file transfer.
