Abstract: The object of the invention is to provide a network system capable of solving the problems above without applying excessive load to the host computer and enabling users to exchange views freely. The network communication system 1 comprises the host device 3, the first communication device 5, and the second communication device 7. The first communication device 5 in turn includes a primary connection information generating means 11, an identity information generating means 12, a major identity information generating means 13, and a transmitting means 14. The second communication device 7 includes a receiving means 15, a storage means 16, a display means 17, a selecting means 18, and a connecting means 19. Therefore, a network system capable of solving the problems above without applying excessive load to the host computer and enabling users to exchange views freely, is provided.

Abstract: In a communication network structure, a communication network system using the communication network structure and a communication method for the communication network system, a plurality of user stations which are connected to one another through bidirectional communication means, and at least one host station which is connected to each of the user stations through bidirectional communication means. The host station holds a data base containing consciousness information in which only each user station's intention of entering the communication network is collected, and communication connection in formation which is required for each user station to directly or indirectly select another user station without going through host station to perform a direct communication therebetween, and each user station holds knowledge information to be delivered between the user stations without going through the host station by the direct communication therebetween.
