Description

[0001]
[Industrial applications]
The present invention relates to a communication server system and an information communication method.
[0002]
[Prior art]
In recent years, software assets such as peripheral devices such as large-capacity storage devices, printers and scanners, various application software, and common databases are shared among a plurality of computer terminals (client terminals) connected by a short-distance communication cable. By constructing a local area network (LAN) or a WAN (wide area network) by connecting a plurality of LANs, these resources are being actively utilized.
[0003]
Also, in the field of communication using public communication lines (ISDN <Integrated Services Digital Network>, PSTN <Public Network>), hardware having a communication function is added to a computer terminal, and the communication is performed from the computer terminal through the communication line. A system for directly performing data communication with a communication terminal in a remote place has attracted attention.
According to this type of terminal, a document or image created and edited on a computer terminal can be directly transmitted and received via a communication line, so that a hard copy or a soft copy of the document or image can be obtained. Can be saved in time, cost, resources, and the like, as compared with a conventionally used method of transferring the data by a communication-dedicated terminal such as a facsimile.
[0004]
Also, by using these terminals, there is no degradation in image quality from the original image caused by image reading or printing processing, so that the image can be transferred with the same image quality as created. There is.
On the other hand, when a server device for integrally managing each client terminal constituting the LAN and performing the operation of the system is provided on the LAN, the server device is provided with the communication function as described above. All client terminals that can access the device can use the communication function described above to send and receive documents from the window of the client terminal.
[0005]
In addition, by adding various processing functions or service functions to the server device, it becomes possible to provide a wider range of communication services to the client terminal. For example, an automatic distribution processing service for automatically transferring a document received from a partner communication terminal to a destination client terminal is one example.
That is, a client identifier is assigned to each client terminal in advance, stored and collectively managed in the server device, and a user who sends a document to the client terminal stores the client identifier in the secondary address of the communication line. Set and send the document. Then, the server device that has received the document determines the client terminal from the client identifier designated by the sender as the secondary address, and performs automatic document transfer processing to the receiving client terminal via the LAN.
[0006]
[Problems to be solved by the invention]
Although the communication server system aims to provide the above advantages to the user, in the above system, the person who sends a document to the client terminal does not know the number of the client terminal to which the document is sent. In this case, the document received by the server device is temporarily stored in a storage device in the server device as an unknown destination document.
[0007]
In this case, the sender of the document informs the user of the receiving client terminal that the document has been transmitted in some form, or manages the contents of the received document stored in the server device in the server device. Until the system administrator reviews the documents, determines who the recipients of the documents are, and manually forwards them to the appropriate client terminals, the recipients will be able to review the documents addressed to them on the client terminals. There is a problem that can not be.
As a result, not only is the immediacy of the received document lost, but if the reception of unknown destination documents overlaps, the capacity of the storage device in the server decreases, and the efficiency of the entire system deteriorates. Then, there is a possibility that the server device falls into an unreceivable state.

Then, the distribution processing unit 30 controls various processes until the received document is transferred to the client terminal.
[0018]
Therefore, the processing performed by the server device 1 according to the present embodiment having the above configuration will be described in detail below, assuming that the server device 1 receives a document.
FIGS. 3, 4, and 5 are flowcharts illustrating a processing procedure performed by the server apparatus 1 when an unknown destination document is transmitted from the external communication terminal 6 to the client terminal 3 according to the present embodiment.
<Description of reception processing>
With reference to the flowchart shown in FIG. 3, the reception processing in the present embodiment will be described.
[0019]
In the secondary storage unit 22 in the server device 1, a client information file is prepared for each client terminal on the LAN. Here, all the unique information set by the user from the client terminal is registered and managed in the file.
When the sender of the document transmits the document from the communication terminal 6 shown in FIG. 1 to the client terminal 3, the communication control unit 23 performs a series of communication of incoming call, line connection, communication function negotiation, data transfer, and line disconnection. The phase is ended, and the acquired document is stored in the primary storage unit 21 (Step S3-1). The communication protocol and various parameters exchanged during communication are also stored in the primary storage unit 21 as needed.
[0020]
When the reception of the document is completed, the communication control unit 23 writes the communication result held in the primary storage unit 21 into a file (hereinafter, referred to as a communication record file) and stores it in the secondary storage unit 22 I do. Further, the distribution processing unit 30 receives the destination information of the received document from the communication record recorded by the communication control unit 23. Then, the value of the client identifier written by the document sender is read into the secondary address in the destination information (steps S3-2 and S3-2a).
[0021]
If the client identifier is included in the secondary address (YES in step S3-3), the document is decrypted (step S3-4). Then, after performing a distribution process (step S3-5) described later, the communication result is written into the reception notification file, that is, the reception notification file is extracted from the secondary storage unit 22, and the received document name and transmission source address Then, the reception time is written in the file (step S3-6).
[0022]
Next, when a transfer command is issued to the LAN control unit 25 in the server device 1, the LAN control unit 25 receiving the command transfers the file to the operation unit 15 in the client terminal according to the identifier. Then, the reception notification file is transferred from the server device 1 to the client terminal (step S3-7). As a result, the operation unit 15 of the client terminal that has received the file reads the reception notification text in the reception notification file and displays it on a display (not shown) (step S3-8).
<Description of distribution processing>
FIG. 5 is a flowchart illustrating a distribution processing procedure according to the present embodiment.
[0023]
The distribution processing unit 30 extracts a client information file corresponding to the above-described identifier, and reads a file format from the client information file (step S5-1). Then, in step S5-2, the current file format is compared with the file format registered in the client information file, and if the current file format is different from the file format in the client information file (step S5). -3, the command is issued to the image processing unit 28 to request the corresponding processing, that is, image processing such as decoding and file format conversion, to convert the document into the specified format. (Step S5-4).
[0024]
Then, the IP address is read from the client information file (step S5-5), and the document after this processing and the IP address are passed to the LAN control unit 25, and a document transfer command is issued. Upon receiving the transfer command, the LAN control unit 25 performs client-server communication with the operation unit 15 in the client terminal 3, and transfers a document to the client terminal 3 indicated by the destination (step S5-6). .
[0025]
On the other hand, if it is determined in step S3-3 in FIG. 3 that there is no input of the client identifier in the secondary address, the distribution processing unit 30 searches for a communication record file in the secondary storage unit 22, that is, described later. A destination search process is performed (step S3-9).
<Description of destination search process>
FIG. 4 is a flowchart illustrating a destination search processing procedure according to the present embodiment.
[0026]
If there is no input of the client identifier in the secondary address, a search is made for a past source address in the communication record file (step S4-1), and this search content is compared with the source address (secondary address). (Step S4-2). Then, when it is determined that the communication record file has the same address as the source address with which communication was performed in the past (the determination result in step S4-3 is YES), the communication record file group whose address matches is determined. Extract (step S4-4).
[0027]
Next, the destination address (destination client terminal) of the file group is searched (step S4-5), and the client terminal having the largest number of destinations among the client terminals as the destination is set as the provisional destination of the received document. Then, the same distribution processing as described above is performed (steps S4-6, S4-6a).
If it is determined in step S4-3 that communication has not been performed in the past, the distribution processing unit 30 decrypts the document (step S4-7), and converts the processed document into a file format. Is stored in the secondary storage unit 22 without performing the conversion (step S4-8).
[0028]
Then, the reception notification file is extracted from the secondary storage unit 22, the received document name, transmission source address, and reception time are written in this file (step S4-9), and a transfer command is issued to the LAN control unit 25 (step S4-9). Step S4-10). When the LAN control unit 25 receiving the command transfers the file to the operation unit 15 in the client terminal, the operation unit 15 reads the reception notification text in the reception notification file and displays it on the display.
[0029]
As described above, according to the present embodiment, when a document whose destination is unknown is received, the destination is determined from the past reception history and distributed, thereby transmitting the document to the receiving user. It is no longer necessary to transfer the document to the recipient via a separate system such as a telephone, or the system administrator can check the contents of the received document one by one and transfer the document to the recipient. Document confirmation becomes easier.
[0030]
In addition, since it is possible to avoid a state where documents with unknown addresses are excessively accumulated in the server device, it is possible to avoid a situation in which the storage capacity for storing documents in the server device is insufficient.
The present invention may be applied to a system including a plurality of devices or an apparatus including one device. Needless to say, the present invention can be applied to a case where the present invention is achieved by supplying a program to a system or an apparatus.
[0031]
