The present invention relates to the integrated processing of documents created by various OA (Office Automation) equipment having a communication function, and in particular, while processing documents created in various types of terminals in a common manner, but the standard in accordance with international standards in the terminal matching device The present invention relates to a document communication control processing apparatus which processes so as to be able to service.

Facsimile terminals have been widely used and their usage forms have evolved from simple inter-terminal communication to e-mail device functions such as broadcasting and group transmission through communication processing devices inside and outside the network.

In addition, OA devices having communication functions, such as word processors and personal computers, are being developed from the conventional stand-alone type to the mesh type. As the private exchange (PABX) is digitalized, the non-switching system is used in the private exchange. The terminal can be accommodated.

In addition, in the environment of companies, the traffic between each place as well as the place of business is on the rise, and therefore, a dedicated private document communication processing system for companies is required. As a result of the standard activities of the message communication system, CCITT released the X.400 series of recommendations, and the environment for standardized implementation of document communication processing devices such as companies mentioned above was established. There is a demand for a system having a function of efficiently providing document communication between and within workplaces through PABX.

Existing electronic mail systems use only the mail function of a general-purpose computer to process documents created from a designated terminal or rely on file transfer using a personal computer (PC) network.

However, since the documents in the actual office transmit documents created from various OA devices by people or FAX, the postal function of general purpose computers is not limited to OA unless there is a system that accommodates various OA devices and provides integrated document processing. There was a problem that did not help.

Accordingly, it is an object of the present invention to provide an apparatus capable of servicing messages of international standards by connecting several OA devices used in document preparation and communication in an office to a single processing apparatus.

FIG. 2 is an image creation processing unit 200 having a processing flow chart as shown in FIG. 2B. The operation of the image processing unit 200 is operated by a request from the central controller 1.

The type of processing required is mainly to convert text codes (e.g. ASCII codes) into image codes that can be printed on fax and to convert the types of image codes already received (e.g. mutual conversion between MH coding and MR coding). It can be divided into two cases. In the case of the code conversion, the image data corresponding to the code value is stored in the image memory using the character generating ROM, and in the case of the image processing, the decoded data is stored in the image memory using the DICEP. The stored image is subjected to a controlled process (e.g., enlargement, reduction, etc.) and coded into a desired fax image using DICEP. The function of the image processing apparatus 4 is terminated by transmitting the coded data to the central control apparatus 1.

The facsimile transmission and reception processing unit 21 of FIG. 2 has a processing flow chart as shown in FIG. 2c. The facsimile transmission and reception processing function is started by the following two cases. The first is service reception due to a call from a user, and the next is a service transmission that calls the system and outputs the service progress to the user. The functions of other modules described later also start processing from the case of service reception and service transmission. In the case of service reception, when a call from the user is detected by ringing through the private switch 100 and notified to the central control unit 1, the central control unit 1 designates the number of the voice text to be guided to the user and sets the fax matching device. (6) requires voice guidance and PB signal reception. The fax matching device 6 instructed by voice guidance extracts the voice data corresponding to the designated voice text number from Epirom, converts it into an analog signal using a codec, and transmits it to the other fax user. The user presses a push button PB (Push Button) after listening to the voice guidance, and the fax matching device 6 detects the PB signal using a DTMF receiver. The received PB data is transmitted to the central control unit 1 again, and the central control unit 1 instructs the transmission of another voice announcement or the next operation. The next operation is in the case of requesting the body of a document after receiving all PB data to perform a service (for a message transmission service) or requesting a reply truncation (for various inquiry services).

If reception of the main body is required, a fax document is received from the status fax, the received document is transmitted to the central control unit 1, and the line is cut. In the case of line disconnection, the line is immediately forwarded. Here, the operation of the rotation transmission is the same as that of hook-on in a general call.

In the case of service transmission, a status fax is called (automatic dialing) to transmit the call result to the central control unit 1. The central control unit 1 then requests the transmission of the fax image, and the fax matching device 6 sends the document to the status fax and then notifies the central control unit 1 of the completion of the document transmission. After that, the line is cut.

The text terminal transmit / receive processing unit 220 of FIG. 2 has a processing sequence as shown in FIG. 2d, and this process is similar to the facsimile transmit / receive process in its flow. However, unlike the case of fax, instead of receiving the voice guidance PB, the control document is received. The control document is a terminal-specific protocol that determines the reception procedure and transfers the received control document data to the central control unit 1 so that the central control unit 1 instructs the following operation as in the case of the fax. Other procedures are the same as in the case of fax, so description is omitted.

The system network communication processing unit 230 of FIG. 2 has the same processing sequence as that of FIG.

The communication with the system network is based on a concept almost similar to the transmission / reception procedure of the fax or text terminal, which has been deprecated. The reception from the counterpart system is started by the central control unit 1 detecting a modem signal (Carrier) in the DSU. If this is notified to the central control unit 1, the reception of the telegraph is requested. The communication between systems uses the full text, not the concept of a control document, but since the CCITT recommends that the text itself should be coded to include the information of the MHS protocol, it is only necessary to send the receiving text itself to the central controller 1. do. When the reception of the telegram is completed, the modem's carrier is turned off, so the call disconnect is recognized. In the case of the transmission, after receiving the connection request from the central control unit 1, the call is made to the other party's modem through the modem's handshaking procedure, and the telegram is transmitted as in the case of the call part text terminal matching device 7. After the transmission is completed, the result is notified by the central controller 1, and the service is terminated through the call disconnection procedure of the modem.

The first protocol processing unit 24 of FIG. 2 converts the received service into a standard protocol that can be processed by the system in cooperation with the facsimile matching device 6 in the processing sequence as shown in FIG. Requesting the fax matching device 6 to convert the service output request (which is described in the system standard protocol format) from the service common processing unit into a full-text format that can be printed on the fax and send it to the other fax. Perform the function.

When a call notification from the FAX matching device 6 is received, PB data is received after requesting to output the voice guidance. The received PB data is converted into internal standard protocol data and then continues the voice guidance PB receiving procedure. After all necessary PB data has been received, the final announcement is sent and it is determined whether to receive the document body or cut the line according to the protocol information created from the receiving PB. If a body is needed, it is requested to receive the body to receive the body, and if the line is to be disconnected, it is instructed to disconnect the line. When such an operation is completed, the written protocol and the received body (only when received) are transmitted to the service common processing unit 260 to request a service. In the case of the service transmission, the image processing apparatus 4 requests processing after layout of the format in order to create an image that can be output to a fax. After receiving the processing result, the fax matching device 6 is connected to the rotation, and after receiving the connection result, the output of the message is requested. After the transmission is completed (after receiving the transmission result, and after disconnection instruction), the service common processing unit 260 returns the completion result of the service transmission.

The second protocol processor 250 of FIG. 2 has the same processing sequence as that of FIG. In the case of facsimile processing, the skeleton of the flow is similar to that of facsimile. In case of service reception, the difference is distinguished between a procedure of receiving a control document and converting it into an internal protocol form and a procedure of converting internal protocol information into a terminal control document when transmitting a service.

The service common processing unit 260 of FIG. 2 has a processing sequence as shown in FIG. 2h.

It is located between the 1 and 2 protocol processing units 240 and 250 of each terminal correspondence and the application service processing units 1-n (270-290) of the system to perform a kind of traffic control. That is, when the service is received, the internal protocol information about the service request is analyzed to deliver the service to the service processing unit that will service this protocol.In the case of service transmission, the protocol processing unit corresponding to the terminal is checked by checking the type of the terminal to output the service. Request transmission.

The private exchange 100 may be any digital private exchange, and the pad 100 may be used. Since the packet data is processed and the PSDN 120 and the PSTN 130 refer to existing data networks and telephone networks, the present invention will be described with reference to the document processing apparatus 140.

1 to 8, the processing method of the present invention will be briefly described. The image creation processing unit 200 of FIG. 2 is a module performed by using the image processing apparatus 4 of FIG. It converts various characters to be converted into fax image data, converts coding schemes, and enlarges / reduces images. The processing request from the central control unit 1 and the transfer of the processing result are performed to the iPSB interface 610 of FIG. 6 and the iPSB interface 804 of FIG. 8, and the image processing apparatus 4 is to be processed.

The processed image data is coded in a format that can be output by facsimile (FAX), transferred to the memory 802, stored, and then transmitted to the central controller 1 using the DMA controller 807 and the iPSB interface 804. do.

The facsimile transmitting / receiving processing unit 210 of FIG. 2 is a module that is performed through the FIU 2 and the fax matching device 6 and is a module that performs data transmission / reception with the facsimile (FAX) using the CCITT T.30 protocol. The T.30 protocol is an internationally standardized communication standard for the communication of group 3 types of facsimile.

The T.30 protocol is recommended by CCITT as a communication protocol of G3 facsimile currently in use on the market. In order to accommodate the facsimile of the present invention, only the T.30 protocol is referred to as the user facsimile should provide the document transmission and reception. For reference, the facsimile T.30 protocol is applied after pressing the communication button of the facsimile machine (in T.30, the phase A is defined as before the communication button is pressed and in this case, the call can be made to a normal telephone). Receives voice announcement PB.

The pixel transmission / reception processing unit 210 will be described by dividing the reception processing and the transmission processing.

In the case of reception of the facsimile, the call from the user is first detected as a ring in the network controller 310 through the private switch 100. The call detected by the ring of the network controller 310 is polled by the CPU 300. Recognize. That is, the ring signal is the ring signal from the private switch 100 is the network control device 310 (of the public network matching device) of the facsimile matching device 6 or the text terminal matching device 7 of FIG. In this case, the call is recognized by detecting the carrier of the modem in the DUS because the dedicated line is used. do.

The detection data is transmitted to the FIU 2 via the RS-232C interface 309 through the serial input / output device 305, and then to the central controller 1 of FIG. 1 through the iPSB interface 610. Go through In the facsimile transmission and reception process, a FIU (2) is involved in the communication path between the fax matching device (6) and the central control device (1), and the FIU (2) is a fax matching device (6) which is extended in the case of the expansion of the receiving line. Since the number of is designed to share the load of the central control unit 1 so that the central control unit 1 of FIG. 1 is not burdensome, the following description describes only the interface of the fax matching unit 6 and the central control unit 1. do. For the call from the user's fax, a voice prompt must be sent so that a user can input various control information (for example, user number, password, service type, counterpart number, etc.) that the user needs to enter or select. The voice guidance text designated by the control device 1 is taken out of the pyramid 301 and sent to the counterpart FAX via the codec 307.

When the user who listens to the voice prompt inputs the corresponding number through the push button PB, the user receives the voice prompt through the DTMF signal receiver 306 and transmits the result to the CPU 300 again. The CPU 300 determines the voice text to be sent next. Repeat the sending instruction again. After all the input information has been received, the modem starts to go through the T.30 protocol procedure of the fax for the reception of the original, at which time the modem 308 is involved. In order to connect the relative codec of the codec 307, the DTMF signal receiver 306, and the modem 308, switching through the relay of the network controller 310 must be performed. Since the reception of the original using the modem 308 is the same as the facsimile communication known to the public, description thereof will be omitted. The received original is divided into blocks of a certain size and sent to the central control unit 1, which is stored in the hard disk under the control of the hard disk driver 11 through the input / output terminal control unit 5.

The following describes the transmission to the facsimile.

With respect to the original to be sent, the central control unit 1 instructs the fax matching unit 6 to transmit, and at this time, the telephone number of the other party's fax is also known. The fax matching device 6 calls the relative fax using the automatic dialing function of the modem 308, transmits the original using the T.30 protocol procedure, and informs the central controller 1 of the result.

The text terminal transmission / reception processing unit 220 of FIG. 2 is a module performed through the LIU 3 and the text terminal matching device 7, and data transmission / reception with the terminal uses a terminal-specific communication protocol. Like the FIU 2, the LIU 3 also serves to share the load of the central control unit 1, so only the roles of the text terminal matching device 7 and the central control unit 1 will be described. The text terminal transmission and reception processing unit 220 will be described by dividing it into the case of reception processing and transmission processing.

In the case of the reception of the text terminal, a call from the user is first detected as a ring through the private switch 100, and the detected call is transmitted to the central controller 1. At this point, communication between the terminal and the text terminal is started. Since the communication method varies depending on the type of terminal, the protocol procedure of the corresponding terminal should be followed. The V.24 interface 408 for error checking and correction of received data may be unnecessary depending on the communication method, but is required as a lower module of most T and X protocols for accurate communication.

The received original is divided into blocks of a certain size and sent to the central control unit 1, which is stored in the hard disk by the control of the hard disk driver 11 through the input / output terminal control unit 5.

Next, transmission to the text terminal will be described.

With respect to the original to be transmitted, the central control unit 1 instructs the text terminal matching device 6 to transmit, and also informs the telephone number of the other party's text terminal. The text terminal matching device 7 calls the relative text terminal using the automatic dialing function of the modems 410 and 411, transmits the original using the protocol procedure unique to the terminal, and then outputs the result to the central controller 1. To tell. The system network communication processor 230 of FIG. 3 is a module that is performed through the LIU 3 and the public network matching device 8 and is a module that processes data transmission and reception through the general leased line and the PSDN 150.

The public network matching device 8 which mainly performs this function includes the data service device 508 and the V. V. text message matching device 7 instead of the modems 410 and 411 and the V.24 interfaces 408 and 409. The difference is that the 35 interface 507 is used, and the actual data transmission / reception procedure follows a general procedure for matching the leased line or the PSDN 150.

9 is a flow diagram according to the present invention, in which a first process of checking a terminal form after detecting a call, and the terminal form of the first process receives a text terminal temporary control information data, provides a temporary voice announcement of a fax terminal, and performs a PB. A second process of receiving control information on a signal, a third process of receiving control information data according to a terminal type in the second process, and converting the internal protocol into information, and converting the information into the internal protocol in the third process A fourth step of checking whether the document transmission service is authorized from the second step; and a fifth step of receiving a message to be transmitted when the document transmission service is detected in the fourth step, detecting a service type, and processing the corresponding service.

Therefore, a specific embodiment of the present invention will be described in detail with reference to Figs. 1-9, and a user who wants to receive a document communication processing service according to the present invention may specify the type of service requested and necessary service control information in case of document transmission. The message must be prepared in advance.

In the case of the user of the text terminal (Text1-Textn), necessary control information and transmission message are prepared in advance by using the terminal's own function, and in the case of a FAX user, a transmission original is prepared. It will be described according to the type of the terminal to be used. That is, the call is detected in step 4a and the type (type) of the terminal is checked in step 4b. In the case of a FAX user, when a system is connected through the private exchange 100 when calling a telephone (MFC telephone) attached to the FAX, the ring signal from the private exchange 100 is received by the facsimile matching device ( 6) is delivered. The facsimile matching device 6 detects a ring request from the private switch 100 to detect that there is a service request, and generates an interrupt to the central controller 1 through the FIU 2.

Since the service request detection is to perform communication processing in the apparatus of the present invention, it is determined that the service from the terminal will be requested after the point of detecting the call from the user terminal. Confirm by receiving.

The interrupt is a communication between the facsimile matching device 6 and the central control device 1 and the FIU 2 for load sharing is interposed between the two devices. The facsimile matching device 6 and the FIU 2 between the FIU It is necessary to process a separate interprocessor communication system between the (2) and the central control unit (1). As described above, a serial I / O (SIO) method is used between the facsimile matching device 6 and the FIU 2, and when the sender writes information to be sent to the SIO port, the receiver SIO processor An interrupt is generated, which is detected by the CPU 600 and reading data from the SIO port. In addition, the communication between the FIU 2 and the central control unit 1 uses a system bus (MultiBus 11 of iNTEL) 621 applied in the present invention, and the iPSB interface described in FIG. The CPU 600 receives the information transmitted from the transmitting side by generating an interrupt in the iPSB interface 610. Therefore, because of this concept, the signal transmission between devices has been described using the term interrupt.

The central control unit (1) requests the output of the voice guidance to the FIU (2) in the process (4c) to facilitate the input of control information to the FAX user, the request is transmitted to the facsimile matching device (6) The signal is communicated to the FAX user via private exchange 100. The FAX user transmits the necessary control information according to the voice guidance of step (4c) to the system in step (4e) by using a button of a PB (Push Button) telephone.

The voice guidance needs to receive necessary service information from the user in order to provide the facsimile service, but a user who is unfamiliar with the apparatus of the present invention needs a method of informing the input procedure.

In the present invention, for this reason, the voice guidance is provided, but the guidance is not always fixed and may not be described in detail because it may vary depending on the application of the system. The following describes only the voice guidance method.

1) All voice texts that need to be output from the system are processed as digital signals and stored in the pyramid 601 in the facsimile matching device 6 and give a door number for each voice text.

2) When the central control unit 1 determines the voice text to be output according to the service procedure, it designates the voice text number to be output to the facsimile apparatus and transmits it to the user.

3) The facsimile answering device extracts the voice data corresponding to the requested voice number and converts it to an analog signal through the CDOEC (codec).

4) The converted signal allows the user who is transmitted to the other fax user through the line to take the following actions.

The control information defines the terminal equipment control procedure for communication services of Recommendation T.62 Teletex or Facsimile of CCITT. In this Recommendation, the substance of a transmission and reception document is referred to as a normal document. A document describing the control method (how to handle it) is defined as a control document. Although there are various contents to be included in the control document according to the application type of the communication service, it is difficult to explain them one by one, but it is obvious that the control document should be prepared in any form in the system providing the communication service of the document. For example, even when sending a document, information such as the sender and receiver's address, document title, delivery priority, etc. should be included in the control document. In the present invention, only the information necessary for constructing the control document is referred to as the control information. It goes without saying that such control information should be expressed in a promised form between the terminal and the communication processing apparatus, but the present invention does not mention the specific technical scheme. Only the control information representation method for the text terminal is recommended as X.430 in the CCITT, and the facsimile is under continuous research. In the present invention, the voice guide PB signal reception method is used to accommodate the facsimile. By converting to a protocol, common processing is performed regardless of the type of terminal.

The input PB signal is transmitted to the central controller 1 through the fax matching device 6 and the FIU 2 for analysis. At this time, the information is not a service type is removed, only the relevant service information is input and the input control information is converted into a protocol (CCITT X.400 series recommended protocol) used in the present invention in the process (4f) and the hard disk driver ( Control is stored as a file on the hard disk. The input processing of this control information repeats voice guidance and PB signal reception until all necessary control information is input. If the service request is a professional transmission in step 4g, the control information is received from the facsimile FAX.

Professional reception from FAX is received in (4h) process by CCITT's T.30 protocol using modem function in facsimile matching device (6). Detects at When the facsimile matching device 6 finishes receiving the full text, the received full text is stored in a file on the hard disk under the control of the hard disk driver 13. The storage processing in the file is performed between the FIU 2 and the input / output terminal controller 5.

Control information and full-text reception from the facsimile FAX are performed by the facsimile transmission / reception processing unit 210 and the first protocol processing unit 240 of FIG. 3 in step 4j-4I.

The following describes a preparation procedure for performing a service of a text terminal user. The text terminal user calls the system through the private exchange 100 using the communication function of the terminal. When the system is connected through the private exchange 100, the ring signal from the private exchange 100 is transmitted to the text terminal matching device 7. The text terminal matching device 7 detects a ring signal from the private exchange 100 (4a), detects that there is a service request, and generates an interrupt to the central controller 1 through the LIU 3. .

The central control unit 1 requests the LIU 3 to receive control information in step 4d, and the request is transmitted to the text terminal matching device 7. The text terminal matching device 7 operates the protocol processing software according to the text terminal type to receive the control information according to the protocol procedure, and analyzes the received control information in the central controller 1. The input control information is converted into a protocol used within the present invention in step 4f, and is stored as a file on the hard disk under the control of the hard disk driver 13. If it is determined that the service request based on the control information is a professional transmission request, the professional reception is performed in step 4h through the same procedure as the input procedure of the control information in step 4g. The storage processing of the received control information and specialization file is performed between the LIU 3 and the input / output (I / O) terminal control device 5.

Control information and full-text reception from the text terminals Text1-Textn are performed in the process 4j-4I of the text terminal transmission / reception processing unit 220 and the second protocol processing unit 250 of FIG.

In this way, when the service request is received from the terminal, the received control information is converted into a protocol of a type that can serve the same regardless of the type of the user terminal, and is processed by the first and second protocol processing units 240 and 250. The service common processing unit 250 may perform a batch processing.

The service common processor 250 processes the document communication service by calling the service processor 1-n (270, 280, 290) according to the service type of the control information. The public network matching device 8 is connected to a system using the same system as the present invention or a system using the same protocol of the international standard, and thus undergoes different procedures with other user terminals. In this case, the protocol conversion processing procedure is omitted. In this case, the system network communication processor 230 immediately moves to the service processor n (290). The service processor n 290 in FIG. 3 thus becomes a mailing service processor, and the other service processor 1-2 (270, 280) becomes a service processor for other purposes.

The inter-system communication processing unit 230 operates the LIU 3 and the public network matching device 8 to control connection processing with other systems, but each independent service processing unit 1-n in step (4j) depending on the type of service. When the processing at (270-290) is completed, the service processing result should be output to the terminal. In this case, the control information and the professional reception are reversed.

In particular, in the case of the output to the facsimile user, since the protocol information used in the system should be output as an image, the image creation processing unit 200 undergoes an image conversion process. Image conversion processing is performed in the image processing apparatus 9, which is hardware. In this apparatus, a character image is generated from a character code, a figure image is generated from a figure command, a layout of a generated image is generated from necessary layout information, and the like. To process. The image processing apparatus 9 can be used to convert the full text received from the text terminal Text1-Textn into a document for facsimile (FAX) through the same procedure. In the case of FAX, the output document is printed like normal FAX communication. In the case of text terminal, the control information and the message sent from the system are displayed according to the processing function inside the terminal. do. Therefore, the form of control information between the user terminal and the system must be made in advance. The above provisions are based on Recommendation X.430 of the CCITT. Recommendation X.430 is necessary to connect teletex terminals to message communication systems of international standards. It recommends the control procedures and the presentation of control information.

The CCITT X.430 Recommendation is recommended for the general mailing function, but a new control information format may be defined for other services (e.g. filing services, bulletin board services, circular services, etc.) if necessary.

Without departing from the basic spirit of the present invention, those skilled in the art can easily implement the expansion of service terminals and the increase of service termination.

In other words, the expansion of the terminal may be performed by attaching a matching device for processing protocols between terminals with each terminal and a control device of the matching device in hardware, and designing a transmission / reception processing unit and a protocol change processing unit with the corresponding terminal in software. The expansion of the service type is made possible by additionally designing the service processing unit in FIG. 3 and extending the format of control information related to this service by CCITT X.430 Recommendation.

As described above, it is possible to integrate and accumulate documents that can occur in the office, reduce the expenses related to the creation and retrieval of documents, and also improve the document creation, editing, and communication functions in the terminal device. In combination with ISDN, it has the advantage of excellent processing of additional services such as information processing.
