COMMUNICATION SYSTEM, SERVER APPARATUS, TERMINAL, SERVICE METHOD, TERMINAL METHOD AND PROGRAM

摘要

PROBLEM TO BE SOLVED: To provide a communication system and the like that are suitable to allow the history of interaction between terminals to be observed from other terminals.

SOLUTION: In the communication system 200, terminals 201 are introduced to each other by a server apparatus 209 to start interaction such as a network match, and other terminals 201 are allowed to have the history of interaction delivered in the command of the server apparatus 209. A predetermined threshold is set for the number of other terminals 201 having direct delivery from each interacting terminal 201. Until the threshold is reached, the server apparatus 209 commands direct delivery from the interacting terminal 201. When the threshold is reached, the server apparatus 209 first receives delivery from the interacting terminal 201 and commands a new terminal 201 requesting interaction history delivery to receive a relay therefrom. Alternatively, the terminals 201 having already had the history delivered may be indicated to redistribute it.
