Patent ID: 8079908

Claim:
A game network construction method for a network game system comprising a plurality of user terminals, the method comprising: constructing a star peer-to-peer network in which one of the plurality of user terminals is set as a host terminal and the other of the plurality of user terminals are set as client terminals; starting a network game in a plurality of user terminals which have been connected to the star peer-to-peer network; constructing a mesh peer-to-peer network from the star peer-to-peer network by sequentially establishing connections between the client terminals which have been connected to the star peer-to-peer network; and while the mesh peer-to-peer network is constructed after the network game is started, (a) performing transmission and reception of game data, which is required for the network game to advance, between client terminals which have established a connection therebetween, without passing via the host terminal, and (b) performing transmission and reception of game data, which is required for the network game to advance, between client terminals which have not established a connection therebetween yet, via the host terminal by transfer processing of the host terminal.
