DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a network system in which a plurality of devices having different protocols are connected on the same transmission medium, and in particular, a designation of a default directory and a default printer in a file server is prepared for each user. The present invention relates to a network system configured to perform using a file.

[0002]

2. Description of the Related Art Conventionally, a network system in which data processing devices such as a host and a workstation and devices having various service functions such as a file server and a printer are connected on the same network has been known.
In such a network system, if the connected devices have the same protocol, various data exchanges can be performed only by adding a common interface between the devices. On the other hand, if the protocol of each device is different, log in to the gateway that performs protocol conversion by absorbing the difference in the protocol of the connected device, and perform data exchange etc. by accessing the device with the desired service function from the gateway. Is going.

SUMMARY OF THE INVENTION However, the conventional
In a gateway that supports the TCP (Transmissin Control Protocol), the default directory for file services accessed by the user had to be specified in advance using the Change Working Directory command each time the user logged in. Further, it is necessary to specify the default printer when the gateway service is installed, and there is a problem in that operations for data exchange and the like become complicated. Further, there is an inconvenience that the default directory and the default printer cannot be properly used for each user who logs in.

SUMMARY OF THE INVENTION It is an object of the present invention to provide a network system which does not require the designation of a default directory and a default printer at the time of login, and allows the designation of a default directory and a default printer on a user basis.

[0005]

In order to solve the above problems, a network system according to the present invention converts a plurality of terminal devices connected to a network having different communication protocols and a communication protocol between the terminal devices. In a network system having a gateway, the gateway is configured to store information related to each user operating the plurality of terminals as a user profile, and a user operating the terminal device to connect to various servers via the gateway. And setting means for setting default conditions for the user based on the user profile stored in the storage means when accessing. In addition, the present invention is characterized in that, when a user operating the terminal device accesses a print server via the gateway, a default printing related to the user is performed based on the user profile stored in the storage unit. The condition is set automatically. In addition, according to the present invention, when the user who operates the terminal device accesses the file server via the gateway, the setting unit can provide the user on the file server based on the user profile stored in the storage unit. The related default directory is automatically set.

[0006]

When a user using a terminal device logs in to a gateway, default conditions relating to the user are extracted from a user profile corresponding to the user stored in the storage means of the gateway,
Is set. For example, when making a print request to the print server, the print conditions corresponding to this user are set on the print server, and when receiving the service of the file server, the directory corresponding to the user on the file server is specified. Is done. This eliminates the need to specify a default directory, etc., which was previously performed every time the user logs in.By preparing a user profile for each user, the user can specify the default directory to use and set print conditions. Because it is possible, the default directory and the like can be used for each user.

[0007]

An embodiment of a network system according to the present invention will be described below with reference to the drawings.

FIG. 1 is a block diagram showing a basic configuration of a network system according to the present invention. In the figure, reference numeral 11 denotes a host corresponding to the TCP / IP protocol;
Is a printer that executes a print service, which corresponds to the XNS (Xerox Network System) protocol, 13 is a file server that executes the file service, which corresponds to the XNS protocol, 14 is a workstation that supports the XNS protocol, and 15 is a XNS protocol. A home file server 16 that supports and executes a file service is a gateway that supports the TCP / IP protocol and the XNS protocol and exchanges data between the host 11 and the file server 13 or the printer 12.

The home file server 15 stores user-specific information when a user logs in to the gateway 16 in a user profile 1 for each user.
7 is stored. FIG. 2 is an explanatory diagram showing an example of the format of the user profile. The user profile is provided with items such as a default directory 21, a default printer 22, and a print parameter (designation items at the time of printing) 23. The user can arbitrarily set a default directory to be accessed and a name of the default printer. can do.

In a system constituted by a network as shown in FIG. 1, user profiles in the format shown in FIG. 2 are stored in advance in the home file server 15 by the number of users. User is Host 1
1 or the workstation 14 connects to the gateway 16 and logs in, the gateway 16 reads the user profile of the home file server 15 and
Transfer the file to the default directory or default printer.

For example, a file of the host 11 corresponding to the TCP / IP protocol is transferred by a file transfer command.
When transferring to a file service that supports the XNS protocol, the default directory set in the user profile is used as the transfer destination directory. When a file of the host 11 corresponding to the TCP / IP protocol is transmitted to a print service corresponding to the XNS protocol by a print command, a default printer and print parameters set in a user profile are used.

The user profile includes a user command (eg, Change Local Print Parameters, Ch).
ange Working Directory) etc.
When the logoff procedure is performed by the user,
The state immediately before that is held and stored. When the user logs on again, the data set in the state when the user last logged off is used.

Next, a processing procedure of the gateway 16 when various services such as a default directory are designated by the user profile will be described with reference to a flowchart of FIG.

When the gateway 16 receives a login from a user (step 101), the gateway 16 reads the user profile stored in the home file server 15 (step 102), and a default directory or a default printer is set for the logged-in user. Is determined (Step 10
3). If a default directory or the like is set in the user profile, the file is transferred to the default directory or the default printer set in the user profile (step 104). On the other hand, if a default directory or the like is not set in the user profile, an error message is output to the user (step 105). Then, after receiving the designation of the default directory or the default printer from the user (step 106), the file is transferred to the designated default directory or default printer (step 107). When the logoff procedure is executed, the gateway 16 stores the default directory or the default printer set at the time of logoff in the user profile (step 108).
The process ends.

As described above, the information such as the default directory and the default printer of the file service accessed when the user logs in to the gateway is collectively managed by the user profile prepared for each user, so that the default directory at the time of login is obtained. This eliminates the need for designation, and can simplify operations for data exchange and the like. By preparing a user profile for each user, a default directory and a default printer can be specified for each user.

In the above-described embodiment, an example has been described in which TCP / IP and XNS are used as network protocols. However, other protocol systems may be applied as long as they have equivalent functions. .

[0017]

As described above, according to the present invention, information relating to each user operating a plurality of terminals is stored as a user profile, and the user operating the terminal device accesses various servers via the gateway. In this case, since the default condition relating to the user is set, the condition setting corresponding to the user can be performed for each user. Further, according to the present invention, when the user operating the terminal device accesses the print server via the gateway, the default print conditions relating to the user are set, so that the print conditions corresponding to the user are automatically set. Can be set to In addition, the present invention is configured such that when a user operating a terminal device accesses a file server via a gateway, a default directory for the user on the file server is set, so that a default directory corresponding to the user is set. Can be specified automatically.
