DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a network coordination device for realizing coordination between different network systems.

[0002]

2. Description of the Related Art Network systems having functions such as electronic mail, electronic conference rooms, and electronic bulletin boards are widely used. Many of these are individually constructed, and few have a link function with other network systems. Japanese Unexamined Patent Publication No.
Japanese Patent Application Laid-Open No. 234541 discloses an e-mail exchange means for connecting each network, sets respective coordination IDs for accessing each network connected to the e-mail exchange means, and accesses the network A using the coordination IDA. A technique for transmitting to B using the cooperation IDB is disclosed.

[0003]

When each network is not linked, the user needs to subscribe to all the required networks, obtain the respective user IDs, and log in to each network separately, which is complicated. Become. In the case of JP-A-2-234541, since the message sent to the network B is transmitted by the cooperative IDB, there is a problem that the original sender name of the message cannot be directly known.

[0004] The present invention has been made in view of the above-described problems, and has as its object to provide a network cooperation apparatus that can transmit a message by the sender name of the message.

[0005]

FIG. 1 is a diagram illustrating the principle of the present invention. In a network linking apparatus having a link ID for connecting a plurality of networks and accessing each linking network, a user ID for each of a plurality of predetermined networks accessed by each user
When a message from the connected network A to the connected network B is received from the network A using the corresponding cooperation ID 34, the message is transmitted from the user ID of the sender of the message. A user ID for extracting a user ID 35 of the source user to the network B using the user ID correspondence table 33
An extraction unit 32 is provided, and the extracted user ID 35 is used to transmit to the network B.

When the message to be transmitted to the network B is addressed to an electronic conference room having no registration qualification, the transmission source user of the network A is notified by e-mail that the message cannot be transmitted to the network B. It is like that.

Further, a user ID for the network B
When 35 is not in the user ID correspondence table 33, the message is transmitted to the network B using the cooperation ID 34 corresponding to the network B.

[0008] Further, a message history storage unit for accessing the connected networks with the corresponding cooperation ID 34 and holding a history of received messages is provided.

[0009] Further, it is provided with a data section for encrypting and holding at least a part of the user ID correspondence table 33, and a decryption section for decrypting the encrypted data.

[0010]

The user ID correspondence table 33 stores a list of user IDs 35 for each network that a user wants to use for networks connected to the network coordination apparatus. That is, if the user wants to access the networks A, B, and C, the user IDA to the network A, the user IDB to the network B, and the user IDC to the network C are described. The network cooperation apparatus accesses each connected network with the cooperation ID 34 corresponding to each network. In other words, the cooperation IDA for the network A, the cooperation IDB for the network B, and the cooperation IDC for the network C.
To access. The network cooperation apparatus monitors at regular time intervals whether there is a message to be transmitted using the cooperation ID 34 corresponding to each connected network. When accessing the network A, a message to be transmitted to the network B is detected.
The extraction unit 32 checks the user ID of the sender of the message, extracts the user ID 35 of the user who accesses the network B from the user correspondence table 33, logs in to the network B with the extracted user ID 35, and transmits the message. I do. By doing so, the network B
Then, the sender can be confirmed from the logged-in user ID 35. When transmitted by the cooperation ID 34, the transmission source cannot be confirmed on the receiving side.

[0011] Even if the user has the user ID 35 necessary to access the network, the electronic conference room still requires eligibility, and if he does not have this eligibility, he cannot send a message to the electronic conference room. Can not. In this case, the sender of network A is notified that transmission to network B is not possible by e-mail.

When a user who does not have the user ID 35 required to access the network accesses the network, accesses the network D in the above example, in this case, the user ID correspondence table 33 Is the user ID of the sender's network D
Since 35 is not described, the network cooperation apparatus logs in to the destination network with the corresponding cooperation ID 34 and transmits a message. In this case, the sender cannot confirm the sender.

Each time a message is received by accessing the linked network with the corresponding cooperation ID 34, the received message is stored in the message history storage unit. As a result, even in the case of a network having no message storage function, it is possible to determine whether an accessed message is unread or already read, so that only unread messages can be read.

By providing a device for encrypting part or all of the user ID correspondence table 33 and decrypting it, it is possible to prevent leakage of passwords and the like.

[0015]

Embodiments of the present invention will be described below with reference to the drawings. FIG. 2 is a block diagram showing the configuration of the present embodiment.
In this embodiment, a message is received from the network 10,
A case where a message is transmitted to the network 20 will be described. The same applies to the reverse direction. Further, although the present embodiment has shown the case where there are two networks, the same applies to the case where there are two or more networks.

The networks 10 and 20 include an electronic mail, an electronic conference room, and electronic bulletin boards 11 and 12. Here, the electronic conference room refers to a communication system in which persons registered in the conference can participate, post a theme, freely post opinions on the theme, and obtain opinions of others.

The cooperative system 30 receives a message from the network 10 and stores the message. The message storage unit 40 stores the message. The reception operation unit 36 controls the storage of the message received by the message storage unit 40. Message history storage unit 3 that stores a list of messages
9.When a message is received, the message list is read from the message history storage unit 39, and if the message is a new message, the message history operation unit 38 and the message received from the message storage unit 40 are added to this list. User ID extraction unit 32 that extracts the user ID of the user), extracts the user ID 35 to the destination network corresponding to the user ID from the user ID correspondence table 33, and reads the message stored in the message storage unit 40. , A transmission operation unit 37 for transmitting to the destination network with the user ID 35 extracted by the user ID extraction unit 32, and a control unit 31 for controlling these units.

FIG. 3 shows an example of the user ID correspondence table 33.
The user ID 41 in the network 10 is a password 42,
It comprises a user ID 43 and a password 44 in the network 20 corresponding thereto. In this case, the number of connected networks is two, but in general, there are sets of user IDs and passwords as many as the number of connected networks.

Next, the operation will be described. 4 and 5 are operation flowcharts. In FIG. 4, the cooperation system 30 accesses each connected network at regular time intervals using the corresponding cooperation ID 34.
First, the user logs in to the network 10 with the cooperation ID 34 (step 50). It is checked whether or not the network 10 is a system that leaves a reception history (step 51). If the system does not leave a reception history, a reception list that is a list of messages received from the network 10 is read from the history storage unit 39 (step 52).
. If the system is to leave a reception history, it is checked from the reception history or the list read from the history storage unit 39 whether there is a message that has not been received (step 53). If not, the access to the network 10 is terminated. (Step 66). If there is a message that has not been received, the message is received and stored in the message storage unit 40 (step 54). If the network 10 is a system that retains the reception history (step 55), after receiving the message, log out of the network 10 (step 5).
7) If the reception history is not left, the message received and stored in step 54 is written in the reception list read from the history storage unit 39 (step 56), and then the user is logged out of the network 10 (step 57).

Turning next to FIG. 5, the user ID extraction unit 32
If there is a received message (step 58), the user ID of the writer of the received message is extracted from the message storage unit 40 (step 59). Next, the user ID 35 of the network 20 corresponding to the user ID of the network 10 is extracted from the user ID correspondence table 33 (step 60).

When the user ID 35 is extracted, the user logs in to the network 20 with this user ID 35 (step 6).
1) If the user ID 35 cannot be extracted, the network 20
Login to (step 61). At this time network 2
It is checked whether or not 0 is an electronic conference room or an electronic bulletin board that cannot be used unless registered in advance (step 62), and if it is not registered, the transmission operation unit 37 does not transmit a message and the network 10 This message is notified to the user ID by e-mail (63). If it is registered (step 62), the message is read from the message storage unit 40 by the transmission operation unit 37, the message is transmitted to the e-mail, the conference room, and the bulletin board 21, and the message is deleted from the message storage unit 40. (Step 64) and log out of the network 20 (Step 64).
