Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention is used in the field of using a communication network such as a LAN (Local Area Network) and relates to an automatic connection system for connecting various terminals such as workstations to the communication network.

[0002]

2. Description of the Related Art Conventionally, when a communication terminal is connected to a LAN or the like, a connection environment is set in advance for a communication management terminal (hereinafter referred to as a server), which is a connection destination of the communication terminal, and communication is performed with it. The connection environment was also set up for the terminal.

FIG. 6 shows a state in which a plurality of servers A and B and already connected terminals are connected to the LAN 1, and a new connected terminal is about to be connected to the LAN 1. Server A
It has an information file corresponding to the ID number of the connected terminal, and the mail processing of the connected terminal based on the ID number,
We manage documents. On the other hand, in the already connected terminal, its own ID number, the address of the management server, etc. are defined as the connection environment. In this way, if the connection environment is not prepared for both the server and the connection terminal, data cannot be transmitted and received between them.

When the newly connected terminal is connected to the LAN 1 to be managed by the server A, it is necessary to make a physical connection and a logical connection. The physical connection is to mechanically and electrically connect the input / output terminal of the new connection terminal and the connection terminal of LAN1. The logical connection is to match the connection environment on the server side and the connection environment on the new connection terminal side as described above.

If the connection environment prepared on the server side is not set on the new connection terminal side as determined by the connection environment prepared on the server side, the connection between the two is completely impossible. There should not have been one mistake.

However, in the conventional logical connection method, the environment is set manually on the server side and the new connection terminal side separately, so there is a high possibility that the environment is set erroneously, and this is prevented. Therefore, a great burden was imposed on the operator.

[0007]

As described above, in the conventional connection method of the communication line terminal, the work of setting the information necessary for the connection to the connection terminal and the server is troublesome and there is a possibility of erroneous input. Therefore, there was a problem in workability and reliability.

The present invention has been made in view of the above circumstances, and it is possible to realize complete automation in logical connection of terminals, reduce the burden on the operator, and improve the efficiency of work required for logical connection. It is an object of the present invention to provide an automatic connection method for communication line terminals that can be used.

[0009]

In order to achieve the above object, the automatic connection system for a communication line terminal of the present invention is to connect a new connection terminal to the communication line by physically connecting the new connection terminal to the communication line. Broadcasting a new connection declaration simultaneously, receiving the contents of the new connection declaration at a specific communication management terminal connected to the communication line, and creating terminal connection information of the new connection terminal; The step of simultaneously broadcasting the terminal connection information created on the management terminal on the communication line, and the terminal connection information sent on the communication line is received by the new connection terminal and the information for the logical connection after that is created and the terminal is created. And the step of setting in.

[0010]

According to the communication line terminal automatic connection system of the present invention, when a terminal is physically connected to a new communication line, a "new connection declaration" is issued to the entire communication line. When this is acquired in advance by the communication management terminal scheduled to be connected to the terminal, unique connection information for the newly connected terminal is created. The connection information is transmitted to the entire communication line again. When the newly connected terminal receives the connection information, it creates information for logical connection and sets it in the terminal. In this way, a connection environment that matches each other is automatically set for both the communication management terminal and the new connection terminal.

[0011]

EXAMPLES Examples of the present invention will be described below.

FIG. 1 shows functional blocks of a server and a connection terminal in a communication network according to an embodiment of the present invention. The server determines the content of the data received from the communication line 10 by the received data determination unit 11. In addition, the reservation flag generation unit 12 and the already-connected flag generation unit 13
Two types of flags, a reservation flag and an already-connected flag, can be set. The connection information of the new connection terminal is created by the terminal information generation unit 14. The terminal information generation unit 14 allocates a free area of the identification information table 15 with the unique ID information prepared in advance as a key to a newly connected terminal, and ID information of the allocated area and address information to which the ID information corresponds. Etc. as connection information. The connection information is sent from the transmission processing unit 16 to the communication line 10 together with the address of the server.
Broadcast to.

In the connection terminal, the received data determination unit 17 determines the content of the data taken in from the communication line 10. Further, the existing connection flag generation unit 18 and the new connection flag generation unit 22 can set the existing connection flag and the new connection flag. The logical connection information generation unit 19 creates the connection information of the own terminal necessary for the logical connection. When the logical connection information generation unit 19 creates the connection information of its own terminal, the automatic initialization generation unit 20 is activated and the restart process is executed. The connection environment information storage unit 21 is a unit in which the connection information created at the time of restart by the automatic initialization generation unit 20 is stored.

The operation of the present embodiment will be described by taking as an example a system in which a plurality of servers and connection terminals configured as described above are connected to the communication line 10. A connection terminal that is already logically connected to the communication line 10 is called an already connected terminal,
A connection terminal that is logically connected to the communication line 10 from now on is called a new connection terminal.

When the newly connected terminal is logically connected to the communication line 10, the reservation flag generator 12 of the server is connected before the physical connection.
In response, a command to the effect that it is the management station of the terminal to be connected is input. Reservation flag generation unit 1 that received this command
2 sets a reservation flag. This state is shown in FIG.

Next, the newly connected terminal is physically connected to the communication line 10. This physical connection issues a new connection declaration and broadcasts it on the communication line 10, and the new connection flag generation unit 22 sets a new connection flag. FIG. 3 shows a state in which the new connection declaration is broadcast.

Two servers A and B are connected to the communication line 10, and the server A serves as a management station of a newly connected terminal. When receiving the new connection declaration from the communication line 10, the reception data determination unit 11 of the server A determines whether or not the reservation flag is set in its own station. If the reservation flag is set, the terminal information generation unit 14 creates unique terminal connection information for the newly connected terminal.

The terminal information generation unit 14 uses the identification information table 1
An unused area (a different ID is assigned to each area) is selected from 5. Since the ID of the used area is assigned to the connected terminal, the same terminal information does not exist on the communication line 10.

On the other hand, in the server B, the received data judging section 11
When the new connection declaration is received at, since the reservation flag is not set in the own station, the existing connection flag generating unit 13 is instructed to set the existing connection flag. When the received data determination unit 17 of the already connected terminal receives the new connection declaration, it instructs the already connected flag generation unit 18 to set the already connected flag. This state is shown in FIG. Next, the terminal connection information created by the server A is broadcast from the transmission processing unit 16 onto the communication line 10. This state is shown in FIG.

Of the terminals that have received the broadcast, only the terminal for which the new connection flag is set, that is, the new connection terminal, takes in the terminal connection information from the server A and reflects it as the connection environment. The terminal for which the connected flag is set ignores the terminal connection information received from the server A and erases the connected flag.

In the newly connected terminal that has fetched the terminal connection information from the server A, the logical connection information generation unit 19 temporarily stores the terminal connection information as environment information for subsequent line connection. When the environmental information is stored, the automatic initialization generation unit 20 resets it. As a result, the environment information is stored in the connection environment information storage unit 21 and is reflected in the newly connected terminal.

As described above, according to this embodiment, the newly connected terminal is physically connected to the communication line 10 to broadcast the terminal connection request broadcast, and the server to be managed which receives the broadcast automatically obtains the logical connection information. Is generated and the logical connection information is returned to the new connection terminal to automatically set the environment for the logical connection, so the work of manually inputting the connection information separately for the server and the connection terminal can be reduced, and the connection with the server can be reduced. The logical connection with the terminal can be automated. The present invention is not limited to the above embodiments, and various modifications can be made without departing from the gist of the present invention.

[0023]

As described above in detail, according to the present invention, it is possible to realize full automation in the logical connection of terminals, reduce the burden on the operator, and improve the efficiency of the work required for the logical connection. A line terminal automatic connection system can be provided.
