An example of the processing flow of FIG. Next, the operation processing of the present invention will be described in detail according to this processing flow.

When the relay control device 1 receives a connection request from the user terminal 2 by designating the connection number to the host device 9-i, as shown in the processing flow of FIG. By referring to the first management area 70 of the connection information file 7, the specified connection number is assigned to the first management area 70.
If it is registered, the line connection procedure indicated by the connection number is specified, and if it is not registered, the line connection procedure indicated by "other" is specified.

For example, from the user terminal 2 the connection number "12"
When there is a connection request to the host device 9-1a by specifying 34 ", the line connection procedure 1 is specified according to the management data of the first management area 70 shown in FIG. 3, and the connection number" 3564 "is specified.
When there is a request for connection to the host device 9-3m by designating, the line connection procedure 3 is specified according to the management data of the first management area 70 shown in FIG.

When the registration of the connection number is determined in step 1, the process proceeds to step 2 and the connection information file 7
By referring to the third management area 72, the board 8-i that executes the line connection procedure specified by the connection number registration is specified. On the other hand, when it is determined in step 1 that the connection number is not registered, the process proceeds to step 3 and the second management area 71 of the connection information file 7 is referred to, so that "others correspond to the line connection procedure". Judge whether "relationship" is set to valid or invalid.

When it is determined in step 4 that no security is set according to this determination process, that is, it is determined that "correspondence between other and line connection procedure" is set to valid. When doing so, proceed to step 2 and the third management area 7 of the connection information file 7
By referring to 2, the board 8-i that executes the line connection procedure specified without the connection number is specified. On the other hand, according to this determination processing, when it is determined in step 5 that security is set, that is, when it is determined that "correspondence between other and line connection procedure" is set to invalid, Proceeding to step 6, a message indicating that connection is impossible is output to the user terminal 2 which is the connection request source, and the processing ends.

In this way, in step 2, for example, when there is a connection request to the host device 9-1a by designating the connection number "1234" from the user terminal 2, the line connection procedure 1 is executed as described above. I will identify it, so at this time,
When the two boards 8-1 and 2 are specified according to the management data of the third management area 72 shown in FIG. As described above, the line connection procedure 3 is specified, and at this time, the two boards 8-4,5 are specified according to the management data of the third management area 72 shown in FIG.

When the board 8-i is specified in step 2, the process proceeds to step 7, and if there are a plurality of specified boards 8-i, the fourth management area 7 of the connection information file 7 is selected.

When the line connection procedure and the board 8-i that executes the line connection procedure are determined, the process proceeds to step 9, where the board 8-i is used and the user of the connection request source follows the line connection procedure. A connection is established between the terminal 2 and the host device 9-i that is the connection request destination. Then, in step 10,
The management data in the third management area 72 of the connection information file 7 is updated in response to the increase in the number of user terminals 2 connected to the board 8-i by one due to the connection processing. For example, when the board 8-1 is specified in step 7, the number of connected boards 8-1 registered in the third management area 72 is increased by one, and when the board 8-5 is specified, the third board 8-1 is connected. The number of connected boards 8-5 registered in the management area 72 is increased by one.

Then, in the following step 11, when the communication process between the connected user terminal 2 and the host device 9-i is started and a disconnection request is issued from the user terminal 2, in the following step 12, the host device is connected. Disconnect from 9-i,
Finally, in step 13, the third management of the connection information file 7 is performed in response to the decrease in the number of user terminals 2 connected to the board 8-i used by the disconnection process. The management data in area 72 is updated. For example, when the board 8-1 is used in step 11, the number of connected boards 8-1 registered in the third management area 72 is 1
3 when you are using board 8-5
The number of connected boards 8-5 registered in the management area 72 is decreased by one.

In this way, according to the present invention, the user operating the user terminal 2 can access the desired host device 9-i by simply specifying only the connection number. Moreover, the public network 5-3
It becomes possible to access the host device 9-3 housed in the server even if the connection number is not registered in the connection information file 7.

That is, as shown in FIG. 5, in the connection information file 7, the correspondence between the connection number "1234" and the line connection procedure 1 and the connection number "5678" and the line connection procedure 2 are shown.
When the user terminal A designates the connection number “1234” and issues a connection request to the host device A when the correspondence relationship between the user terminal A and the other and the line connection procedure 3 are registered. The relay control device 1 specifies the line connection procedure 1 for realizing the connection with the host device A, and connects with the host device A according to the line connection procedure 1, and
When the user terminal A specifies the connection number “1111” and issues a connection request to the host device C, the relay control device 1
The line connection procedure 3 for realizing the connection with the host device C is specified, and the connection with the host device C is performed in accordance with the line connection procedure 3.
