Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an online computer system in which a plurality of business terminal devices are connected to a host computer and the host computer executes a process based on the business function of the business terminal device. The present invention relates to a business terminal control method in an online computer system for controlling functions.

[0002]

2. Description of the Related Art In an online computer system in which a host computer and a business terminal device are connected via an online network, an online connection request from the business terminal device to the host computer is made in order to prevent intrusion of outsiders. Generally, the usage from the business terminal device is controlled by checking the user ID and the password.

The control contents for controlling the usage from the business terminal device in the conventional online computer system will be described below. That is, as shown in FIG. 6, a user ID and a password are assigned to each business terminal device 50 permitted to connect to the host computer 40 online. On the other hand, the host computer 40
A check table combining a user ID and a password is provided, and the user ID and password input by the user from the business terminal device 50 are collated with the check table.

A user ID is stored in the host computer 40.
Business functions that can be executed are set for each. Therefore, the business function available from the business terminal device 50 is limited to the business function specified by the user ID of the business terminal device 50 registered in the check table of the host computer.

In the conventional online computer system as described above, as shown in the flowchart of FIG. 7, when there is a connection request from the business terminal device 50 to the host computer 40 (step 701), the host computer 40 requests the connection. The business terminal device 50 is requested to enter the user ID and password (step 7).
02).

When the password and the user ID are input from the business terminal device 50 (step 703), the host computer 40 collates the input user ID and password with the check table, and the host computer 40 sends the password from the business terminal device 50. It is determined whether the connection request is a legitimate use (step 704). Here, “valid use” means that the combination of the password and the user ID exists in the check table of the host computer 40.

As a result of the collation, when the connection of the business terminal device 50 is authorized, the host computer 40 processes the business function set for each user ID (step 705). On the other hand, as a result of the collation, if the connection of the business terminal device 50 is not authorized, the host computer 40 stops the connection process of the terminal (step 706).

[0008]

However, in the above-mentioned conventional business terminal control method, it is confirmed that the combination of the user ID and the password input from the business terminal device exists in the check table of the host computer. Then, the business terminal is permitted only to process the business function set for each user ID. For this reason,
The business functions available from the business terminal device are limited to the business functions specified by the user ID. Therefore, when a user with a certain user ID uses another business function that is permitted to another user ID, a connection request from the business terminal to the host computer is made using the other user ID. However, if there is no other user ID, the business function cannot be used.

Further, in the case of a system in which the business functions that can be used in the host computer are limited according to the type of business terminal device, when using a business function other than the business functions that can be used in a certain business terminal device, It is extremely inconvenient because it is necessary to visit another business terminal device that can use business functions and make a connection request. Furthermore, in a system where the business functions that can be used by the host computer are limited according to the type of business terminal device, when the business terminal device fails and cannot be used, it can be used only by that business terminal device. If there is such a business function, there is a problem that the business function cannot be replaced by another business terminal device.

The present invention solves the above-mentioned drawbacks of the prior art, controls the business functions that can be used for each business terminal, and enables the change of the business functions that can be used by the business terminal device, so that other business operations can be performed. It is an object of the present invention to provide a business terminal function control system in an online computer system that can also use business functions set for a terminal device. Further, another object of the present invention is to provide a job in an online computer system capable of continuing the business function of the failed business terminal device by using another business terminal device even if the business terminal device fails. To provide a terminal function control method.

[0011]

To achieve the above object, a business terminal function control method in an online computer system according to the present invention connects a plurality of business terminal devices to a host computer via an online network, In the online computer system in which the host computer executes a process based on the business function of the device, the host computer can execute terminal identification information for identifying the business terminal device and the business terminal device for each business terminal device.
