Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention connects a VAN (value-added communication network) and a subordinate computer terminal via a superordinate computer, and via this superordinate computer, data is transferred between the subordinate computer and the VAN. The present invention relates to a data transmission method suitable for transmitting and receiving data.

[0002]

2. Description of the Related Art Conventionally, for example, when data such as programs and documents are transmitted and received online between a head office or a branch and a work place in a company, each computer terminal installed in the head office or the branch and the work place, respectively. Is connected to the VAN via a telephone line, and data is transmitted between the computer terminals via the VAN. In addition, such a data transmission system using VAN transmits information or data desired to be transmitted from a computer terminal on the transmission side to V
This information or data is sent to the AN and stored in a data storage unit such as a VAN mailbox for each destination.
Then, when receiving the mail at each computer terminal, the VAN is accessed to read the data or information addressed to itself from the data storage unit.

[0003]

However, since each computer terminal in the above conventional data transmission system is connected to the VAN through the telephone line,
There is a problem that an access charge is generated for each transmission / reception to / from the VAN, and the communication cost increases as the data transmission amount increases. Further, in order to solve the above-mentioned problem, a computer terminal installed in a work place or the like is connected to a VAN via an upper computer such as an office computer, and this upper computer enables PC support (file transfer program). ) May be used to send or receive data from a computer terminal to or from the VAN. However, this requires that a PC support transfer request be made each time, which is troublesome. In addition to this, there is a problem in that the selection of the transfer file becomes troublesome, the burden on the operator is increased, and errors are likely to occur. It is also possible to create a PC support transfer request in advance, but this has a problem in that the file name is fixed and the versatility is lacking.

The present invention has been made in view of the above circumstances, and an object of the present invention is to eliminate the need for making a troublesome file transfer request, rewrite a file name in a transfer request, and transfer a file. It is to provide a data transmission method that facilitates selection.

[0005]

In order to achieve the above-mentioned object, the invention of claim 1 becomes the upper computer terminal via a signal line to an upper computer accessible to a VAN via a dedicated line. A lower computer terminal which is connected to a lower computer terminal and transmits data from the lower computer terminal to the VAN via the upper computer, wherein the lower computer terminal functions as the upper computer terminal. Step of selecting a type of transfer file to be transferred to the VAN from the upper computer to the lower computer by an input operation of the input unit of, and setting a disk storing the transfer file in a designated drive File of the file to be transferred to the higher-level computer from the disk. A second step of inputting a drive name and a directory name into the subordinate computer by an input operation of an input unit of the subordinate computer terminal functioning as the subordinate computer terminal; and the input drive name and directory name. A third step of reading a corresponding file list from the disk and displaying it on the display unit of the lower computer terminal, and selecting a file to be transferred from the displayed file list;
A fourth step of rewriting the lower computer side file name in the transfer request to a file name selected from the file list; and the file rewritten in the transfer request functioning as the upper computer terminal. The fifth step of transferring to the higher-level computer by an input operation of the input unit of the lower-level computer terminal and inputting items necessary for storage on the higher-level computer side; and the step transferred to the higher-level computer. And a sixth step of transmitting file data to the VAN by an input operation of an input unit of the lower computer terminal functioning as the upper computer terminal.

According to a second aspect of the present invention, a higher-order computer connected to the VAN through a dedicated line is connected to a lower-order computer terminal which can be the higher-order computer terminal via a signal line, and the higher-order computer terminal is connected to the higher-order computer terminal. Is a data transmission method for fetching data from the VAN to a lower computer via the computer, and the VAN is operated from the upper computer by an input operation of an input unit of the lower computer terminal functioning as the upper computer terminal. Access the data to the VAN
From the upper computer to the first step,
A file to be transferred to the lower computer is selected from the file list of the data received from the VAN displayed on the display unit of the lower computer terminal functioning as the upper computer terminal, and the lower file is selected for the selected file. A second step of inputting a drive name, a directory name and a file name to be stored on the computer terminal side of the computer to the upper computer by an input operation of an input unit of the lower computer terminal functioning as the upper computer terminal; A third step of transferring the input drive name, directory name and file name to the lower computer by an input operation of an input unit of the lower computer terminal functioning as the upper computer terminal; Based on information transferred from the computer Fourth rewrite file name in the transfer request Te to a file name for the lower computer terminal
And a fifth step of transferring the rewritten file data from the upper computer to the lower computer terminal by an input operation of an input unit of the lower computer terminal functioning as the lower computer terminal. It is equipped with and.

[0007]

According to the present invention, when data is transmitted from the lower computer terminal to the VAN, a list of transfer files is displayed on the display unit of the lower computer terminal, and a file to be transferred to the upper computer is selected from this file list. Then, after automatically rewriting the file name for the transfer request to the selected file name, the transfer request is executed to transfer the requested data from the lower computer to the upper computer, and from the upper computer. VAN
Send to. In addition, when the data received by the VAN is taken into the lower computer, the VA is used by the upper computer.
Receive the file from N, select the file you want to transfer from the list of received files, and transfer the drive name, directory name and file name to be saved on the lower computer terminal side to the lower computer corresponding to this file. Then, the file name in the transfer request is rewritten to the lower computer terminal side file name according to the transfer content, and then the transfer request is executed to transfer the data of the file received by the upper computer to the lower computer terminal. Therefore, it becomes possible to perform data transfer processing interactively while looking at the display screen of the upper or lower computer terminal, making it unnecessary to create a troublesome file transfer request, rewriting the file name in the transfer request, and transferring the transfer file. Selection becomes easy.
