PURPOSE: To suppress the increase of the required throughput of a terminal accompanying the increase of the number of users in a system in which the plural terminals perform communication through a network and a virtual space where the respective users can move around is realized on the network. CONSTITUTION: The terminals in a close distance on the virtual space are turned to a group, one terminal within the group is defined as a server, the other terminals are defined as clients and the communication is performed through the server within the group or the communication is performed by broadcasting/ reception within the group. In the case of performing the communication between the groups, the communication is performed only with the adjacent server on the virtual space through the server. The group to which the terminal belongs is changed corresponding to movement within the virtual space. |
