Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

The present invention relates to a file server service apparatus and method using a file server trunk for a private branch exchange.

[0002]

2. Description of the Related Art An example of conventional file access is described in Japanese Patent Application Laid-Open No. 10-105450. In the file access method in the distributed system described in this publication, a client sends a file name to be accessed to a directory server. The directory server calls the file access step of the file server by referring to the map information that associates the file name with the machine name in the machine specifying step, accesses the file to the disk, acquires the file, and transfers it to the client.
When the file name is a logical expression, a real name is obtained by referring to a logical name table in a logical name resolution step of the file server, and the real name is accessed. If there are multiple machines with the specified file name, create a file list, display it to the user, select the machine, and access this machine.

DESCRIPTION OF THE PREFERRED EMBODIMENTS The construction of an embodiment of the present invention will be described in detail with reference to FIGS. FIG. 1 is a diagram showing a configuration of a file server service device of the present invention. FIG.
FIG. 3 is a diagram showing a configuration of a file server trunk of the present invention.

As shown in FIG. 1, a file server service device includes a file server trunk 1 having a folder for managing files on a contractor basis, and a private branch exchange 2 connected to a PHS private network 5, a private network or a public network 8. And PH
S The PHS 3 accommodated in the private network 5, the data terminal 4 connected to the PHS 3, and the F
It comprises an AX communication device 6 and a FAX terminal 7 accommodated in a private network or a public network 8.

As shown in FIG. 2, the file server trunk 1 has a connection line 17 connected to the private branch exchange 2, a line control unit 11 for controlling the line, and an FT for controlling FTP.
A P control unit 12, a file transfer unit 13 for controlling a file transfer special number service, a folder control unit 14 for controlling a folder control special number service, a voice control unit 18 for controlling voice guidance, and an external unit for storing a subscriber file. It comprises a storage device 16 and a file control unit 15 for controlling file access of the external storage device.

Next, the operation of the embodiment of the present invention will be described with reference to FIGS.
This will be described with reference to FIG. FIG. 3 is a diagram showing the operation of the file transfer service of the present invention. FIG. 4 is a diagram showing the operation of the folder control service of the present invention.

With reference to FIG.
When the file transfer special number of the private branch exchange 2 is used using S3, the private branch exchange 2 performs a terminal authentication process (step A).
1). The terminal authentication number is notified to the file server trunk 1, and the file server trunk 1 and the PHS 3 are connected (step A2). The line control unit 11 of the file server trunk 1 connects the connection line 17 to the private branch exchange with the FTP control unit 12 and notifies the file transfer unit 13 of the terminal authentication number. In the file transfer unit 13, since the terminal authentication processing has been completed by the private branch exchange 2, the outgoing PHS
It is determined that the authentication process 3 is completed, and the FTP control unit 1
Then, an FTP login process is performed for Step 2 (Step A3).
The FTP control unit 12 establishes a socket with the data terminal 4 by the login process of the file transfer unit 13. Thereafter, a file is written from the data terminal 4 by the FTP service between the data terminal 4 and the FTP control unit 12,
File reading, file erasing, and file list services are performed (step A4). The file accessed from the data terminal 4 is stored in the contractor folder in the external storage device 16 by the file control unit 15. PHS3
, The FTP logout process is performed and the service is terminated. Also, in response to an FTP logout request from the data terminal 4, the FTP control unit 12
, The line is disconnected from the file server trunk 1 (step A5).

Next, an embodiment of the folder control special number service will be described with reference to FIG. The folder control special number service does not use the data terminal 4 but checks the list of files in the contractor folder stored in the file server trunk 1 only by the PHS 3, deletes the file, transfers the file to another contractor folder, and sends the designated fax number. Is a service that sends files. When the PHS 3 issues a folder control special number to the private branch exchange 2, the private branch exchange 2 performs a terminal authentication process (step B1). Thereafter, the terminal authentication number is notified to the file server trunk 1, and the connection between the file server trunk 1 and the PHS 3 is performed. The line control unit 11 of the file server trunk 1 connects the connection line 17 to the private branch exchange and the voice control unit 18 and notifies the terminal control number to the folder control unit 14 (step B2). Folder transfer unit 1
4 instructs the voice control unit 18 to transmit voice guidance and waits for a service number input. According to the voice guidance, the user of PHS3 inputs a service number (step B3). The folder control unit 14 uses the service number to
The list announcement (step B5), file deletion (step B6), file transfer (step B7), and fax transmission (step B8) are performed. In the case of the facsimile transmission service, the private branch exchange is requested to connect to the facsimile communication device 6, and the facsimile communication device 6 transmits data sent from the folder control unit 14 to the facsimile terminal 7. This service is terminated by disconnecting from the file server trunk 1 by disconnecting from the PHS 3 or ending the service of the service number.

The present invention provides a similar service by connecting a file server trunk to an exchange capable of data communication, such as a public network exchange or an exchange for the next large-capacity portable communication, in addition to the private branch exchange. Is possible.

[0014]

The file server service apparatus of the present invention can realize a file transfer service by FTP within a range in which a private branch exchange can communicate without constructing a LAN network. By the PHS authentication processing, the setting of the network security becomes unnecessary, and the user management of the file server trunk can be managed by registering the special number service.
