[0010]

In the prior art described above, (1) In the case of the prior art 1, since there is only one node in the communication network, a plurality of nodes in the communication network are installed and these nodes are installed. No messages can be exchanged between them.

(2) In the case of the prior art 2, the transfer destination of the message is an adjacent node registered in each node to which the message is transferred. For this reason, the delivery destination of the message is not the destination node desired by the message sender,
According to the registration of the message transfer destination in the node in the communication network that relays the message, it is not possible to control whether or not each node can deliver the message at the message sending side. Further, it is not possible to control whether a message can be read for each user.

(3) In the case of the prior art 3, since the destination of the message follows the registration method of the access to the bulletin board of the node (storage side) in the communication network, the delivery of each node at the message sending side is performed. Availability cannot be controlled. In addition, it is not possible to control whether a message can be read for each user.

(4) In the case of the prior art 4, all the user identification codes corresponding to the bulletin board identification codes to which the message is to be transferred need to be registered in advance. When the user is changed, it is necessary to change the registration of the node (transmission side) in the communication network. When there is a change such as deletion of the registration of the user in each node, the node in the communication network (transmission There may be inconsistencies with the registration contents of the side).

According to the present invention, (1) it cannot be adapted to a communication network composed of a plurality of nodes (prior art 1), and (2) the transfer destination cannot be controlled from the source of the message (prior art 2,
3), (3) Inconsistency tends to occur between the registration change of the identification code of the user at each node and the registration change of the identification code of the user registered as the message transfer destination (prior art 4).
It is intended to solve the conventional drawback.
