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 processing based on the business functions of the business terminal devices. 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 prevented in order to prevent an outsider from entering. In general, the use from the business terminal device is controlled by checking the user ID and the password.

A description will be given below of control contents for controlling use from a business terminal device in a conventional online computer system. That is, as shown in FIG. 6, a user ID and a password are assigned to each business terminal device 50 permitted to connect online to the host computer 40. 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 checked against the check table.

The host computer 40 has a user ID
Each business function that can be executed is set. Therefore, the business functions available from the business terminal device 50 are limited to the business functions specified by the user ID of the business terminal device 50 registered in the check table of the host computer.

In the above conventional online computer system, 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 input a user ID and a password (step 7).
02).

[0006] When the password and the user ID are input from the business terminal device 50 (step 703), the host computer 40 checks the input user ID and password against the check table, and receives the password from the business terminal device 50. It is determined whether or not the connection request is valid use (step 704). Here, the valid use is a case where a combination of the password and the user ID exists in the check table of the host computer 40.

If the result of the comparison indicates that the connection of the business terminal device 50 is valid, the host computer 40 performs the processing of the business function set for each user ID (step 705). On the other hand, if the result of the check indicates that the connection of the business terminal device 50 is not valid, the host computer 40 stops the connection process of the terminal (step 706).

[0008]

However, in the conventional business terminal control system described above, it has been 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, only the processing of the business function set for each user ID is permitted to the business terminal. For this reason,
The business function available from the business terminal device is limited to the business function specified by the user ID. Therefore, when a user of a certain user ID uses another business function permitted for another user ID, a connection request from the business terminal to the host computer is issued using the other user ID. If the other user ID is not known, the business function cannot be used.

Further, in the case of a system in which business functions that can be used by a host computer are limited according to the type of business terminal device, when a business function other than a business function that can be used by a certain business terminal device is used, It is very inconvenient to go to another business terminal device that can use the business function and make a connection request. Furthermore, in a system in which the business functions that can be used on the host computer according to the type of business terminal device are limited, when the business terminal device fails and becomes unusable, it can be used only with the business terminal device. When a business function exists, there is a problem that the business function cannot be replaced with another business terminal device.

[0010] The present invention solves the above-mentioned conventional drawbacks, controls the business functions available for each business terminal, and makes it possible to change the business functions that can be used by the business terminal device. It is an object of the present invention to provide a business terminal function control method in an online computer system that can also use business functions set for a terminal device. Another object of the present invention is to provide an online computer system that can continue the business function of a failed business terminal using another business terminal even when a business terminal fails. An object of the present invention is to provide a terminal function control method.

[0011]

In order to achieve the above object, a business terminal function control method in an online computer system according to the present invention comprises connecting 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 processing based on the business function of the device, the host computer can execute, for each business terminal device, terminal identification information for identifying the business terminal device and the business terminal device An input function validity check table in which function identification information for identifying various business functions is stored in association with each other, and when a processing request specifying the terminal identification information and the function identification information is input from the business terminal device, The combination of the input terminal identification information and the function identification information Determine whether or not it exists in the validity check table, if there is, the processing request is allowed, if not present, comprising a business terminal function control unit that rejects the processing request, the business terminal function control unit, A configuration is provided that includes a change unit that changes the input function validity check table based on a command requesting a change of a business function from the business terminal device.

According to another aspect, the business terminal control unit compares the terminal identification information and the function identification information included in the processing request from the business terminal device with the input function validity check table. And, as a result of the matching by the matching means, if the specified combination of the terminal identification information and the function identification information is present in the input function validity check table, the processing request is accepted. Request reception processing means for notifying the business terminal device of the rejection of the processing request.

According to another aspect, the change means of the business terminal function control unit stores the input function validity check table of the business terminal device in accordance with a command input from the business terminal device requesting merging of business functions. The input function validity check table for the other business terminal device is merged with the input function validity check table according to the command requesting the merging release by merging the input function validity check tables for the other business terminal devices specified by the command. It is configured to have a function to cancel table merging.

A business terminal control unit 12 that determines whether the business function to be executed is appropriate, and a business processing unit 13 that performs execution processing of the business function requested to be processed by the business terminal device 30.

In the present embodiment, the business functions that can be used in the business terminal device 30 are classified into functional units, and function identification information is set for each classified business function. The device 30 identifies a business function that can be used. Input function validity check table 1
1 stores, for each business terminal device 30, a table in which terminal identification information attached to the business terminal device 30 and function identification information of business functions that can be used by the business terminal device 30 are associated with each other. ing.

In the example shown in the figure, function identification information f1, f2, f3 indicating an available business function is associated with the business terminal device 30 of the terminal identification information T1, and the business terminal of the terminal identification number T2. Function identification information f4, f5, f6 indicating an available business function is associated with the device 30. Therefore, in the business terminal device 30 (T1), the business functions of the function identification information f1 to f3 can be executed using the host computer 10, and in the business terminal device 30 (T2), the function identification information f4 to f3 can be executed. f6
Business functions can be executed.

When the host computer 10 inputs a transaction (processing request) specifying terminal identification information and function identification information from any of the business terminal devices 30, the business terminal control unit 12 is included in the input transaction. It is determined whether or not a combination of the terminal identification information and the function identification information exists in the input function validity check table 11. If the combination of the terminal identification information and the function identification information exists in the input function validity check table 11, the input transaction is determined to be valid and sent to the business processing unit 13.

Accordingly, in the illustrated example, the business terminal 30
The transaction requesting execution of the business functions f1 to f3 from (T1) is determined to be valid, and the business processing unit 1
In the case of requesting a business function other than the business functions f1 to f3, the processing request is rejected and the processing is not performed. The transaction requesting execution of the business functions f4 to f6 from the business terminal device 30 (T2) is determined to be valid, and the business processing unit 13 performs the execution processing of the business functions f4 to f6. Even if a business function other than f6 is requested, the processing request is rejected and no processing is performed.

FIG. 2 is a functional block diagram showing the configuration of the business terminal control unit 12. As shown in the figure, the business terminal control unit 12 includes an input / output unit 20 for inputting and outputting data to and from the business terminal device 30, and terminal identification information and function identification information designated by a transaction input from the business terminal device 30. A collating unit 21 for collating information with the input function validity check table 11, and changing the contents of the input function validity check table 11 according to a command input from the business terminal device 30 requesting a change of the business function of the business terminal device 30 The function changing unit 22 and the transaction input from the business terminal device 30 are transferred to the business processing unit 13 according to the collation result of the collation unit 21 or the execution of the business function requested by the transaction is impossible. A request reception processing unit for notifying the business terminal device 30 of the response message;

The input / output unit 20 receives a transaction from the business terminal device 30 and sends it to the collation unit 21 or the request reception processing unit 23. The request reception processing unit 23 sends a response message or the processing result of the business processing unit 13 to the business terminal device 30.

When the transaction from the business terminal device 30 is input, the collating unit 21 searches the input function validity check table 11 for a table relating to the business terminal device 30, and checks the terminal identification information and the function identification information designated by the transaction. And the table. And
If the business function to be executed by the transaction is included in the table, the transaction is determined to be valid, and the request reception processing unit 23 is instructed to transfer the transaction to the business processing unit 13. On the other hand, when it is determined that the transaction is not valid when the business function to be executed by the transaction is not included in the table, the request reception processing unit 23 cannot input data to the business terminal device 30 via the input / output unit 20. Is sent.

The function change unit 22 receives a command (function merge command) for requesting to merge the business function of another business terminal device with the business function of the business terminal device 30 from the business terminal device 30. In the validity check table 11, the table in which the business functions of the business terminal device 30 are registered and the table in which the business functions of the other business terminal devices 30 specified by the function merging command are registered are merged.

Further, when a command (function combination release command) for requesting the release of the business function of the business terminal device 30 is input from the business terminal device 30, the business terminal device 30 in the input function validity check table 11 is input. The table in which the business function of another business terminal device 30 registered by the function merge command is registered is released from the table in which the business function is registered. As described above, the business terminal device 30
The change of the business function is performed by mutually merging or canceling the merging of the tables in which the business functions are registered for each business terminal device 30 in advance. Accordingly, when the business functions are merged for a certain business terminal device 30 and then the merging is released, the table contents of the business functions of the business terminal device 30 return to the initial state.

When the transaction is valid as a result of the collation by the collation unit 21, the request reception processing unit 23
In accordance with the instruction 1, the transaction is executed by the business processing unit 13.
