Abstract

PURPOSE:To automatically retrieve a file to be sent even when no file name is inputted from a caller data terminal equipment. CONSTITUTION:A digital private branch of exchange 10 is provided with a function informing an extension number of a caller data terminal equipment 6 to a server data terminal equipment 5 via a control signal line 12, and the server data terminal equipment 5 is provided with a function retrieving a file to be sent by using a caller extension number as a keyword from files 52, 53, 54 in a hard disk 50 automatically. Thus, it is not required to enter a file name having been required for selecting a file and an opposite terminal equipment is confirmed by using an extension number to secure the secrecy more highly.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a file transfer system, and more particularly to a file transfer system having a function of automatically searching a transmission file.

[0002]

2. Description of the Related Art A conventional file transfer system specifies a file by inputting a file name or the like from a client data terminal to a server data terminal after a data line is connected. Further, in order to maintain the confidentiality of file transmission, the sender has been confirmed by inputting an ID number or the like.

[0003]

However, in this conventional file transfer system, it is necessary to input the file name etc. one by one from the client that receives the data, and it is necessary to check the file name. Then, there was a problem that the work became complicated. In order to keep the secret, there is a confirmation method by inputting an ID number or the like, but it is difficult to keep the secret by limiting the terminal.

The present invention has been made in view of the above-mentioned problems, and provides a file transfer system capable of checking a terminal and searching for a required file without inputting a file name from the client side. For the purpose of provision.

[0005]

To achieve the above object, a file transfer system of the present invention is a file transfer system for transmitting data of a predetermined file from a data terminal of a callee to a data terminal of a caller. Is provided with a search function for automatically searching for the predetermined file based on the extension number.

[0006] Further, a digital private branch exchange connected by a line for digitally multiplexing data communication signals and control signals for communication, one data terminal as a server for transmitting data, and a client for receiving data. In a system including a plurality of data terminals, the digital private branch exchange has a function of transmitting the extension number of the caller to the called party as a control signal and a function of allowing data communication between the data terminals. Then, the data terminal of the server has a function of reading out the extension number of the caller from the control signal, and automatically searches for a file to be transmitted from an external storage device such as a hard disk using the extension number of the caller that has been read out as a keyword. It has a database function and a function of transmitting the data of the file, and the data terminal of the client stores the data. And a function of signal, a configuration equipped with a function of storing data in the external storage device.

[0007]

Embodiments of the present invention will be described below with reference to the drawings. FIG. 1 is a block diagram showing a file transfer system according to an embodiment of the present invention.

In the figure, reference numeral 10 denotes a digital private branch exchange, which comprises a digital line circuit 4, a switch 1 and a digital line circuit 3 for digitally multiplexing and communicating data communication signals and control signals. Reference numeral 2 is a central control unit for making these connections. Further, 5 is one data terminal which serves as a server for transmitting data, and 6 is a plurality of data terminals which are clients for receiving data.

The central control unit 2 of the digital private branch exchange 10 has a function of transmitting the extension number of the caller as a control signal to the callee and a function of causing data communication between the data terminals.

Further, the data terminal 5 of the server has a function of reading the extension number of the caller from the control signal and a file to be transmitted from the files 52, 53 and 54 of the hard disk 50 using the read extension number of the caller as a keyword. It has a database function of automatically searching for the searched file 51 and a function of transmitting the data of the searched file. On the other hand, the data terminal 6 as a client has a function of receiving data and a function of storing the data in the floppy disk 61 of the external storage device.

Therefore, according to this embodiment, the files are transferred as follows. The data line is transmitted from the data terminal 6 of the client to the data terminal 5 of the server. Central control unit 2 of digital private branch exchange 10
Transmits the incoming call processing and the extension number of the client data terminal 6 to the server data terminal 5 via the control signal line 12. The data terminal 5 of the server automatically responds to the incoming call and reads the extension number of the data terminal 6 of the client who is the sender.

The central control unit 2 is a data terminal 5 of the server.
Responded, control switch 1 to control server terminal 5
The data line 11 connects between the client terminal 6 and the client terminal 6. The data terminal 5 of the server selects the data file to be transmitted from the search file 51 of the extension number and the data file name from the data files 52, 53, 54 by using the extension number of the data terminal 6 of the client as a keyword. Then, the selected data file is transmitted to the data terminal 6 of the client via the data line 11. The data terminal 6 of the client controls the floppy disk 61 and saves the received data as a file.

In the above embodiment, if the ID number method is used together, a higher degree of confidentiality can be maintained.

[0014]

As described above, according to the file transfer system of the present invention, the client terminal is automatically recognized by the extension number of the caller notified to the server terminal by the control signal, and the file to be transmitted by the server terminal is selected. Search automatically.
This has the effect of eliminating the need to specify the file name from the client side. Further, in order to keep the secret, unlike the confirmation method by inputting an ID number or the like, it is possible to automatically confirm the terminal and keep the secret.
