SIP BASED VOIP MULTIPLAYER NETWORK GAMES

摘要

This invention is directed to a system and method for the close coupling of Session Initiation Protocol (SIP) based Voice over Internet Protocol (VoIP) with multiplayer network games. Game state dependent voice communications ar e used as another method of player interaction in the game environment. The system uses SIP enhanced game servers and conference servers with audio mixi ng capabilities, and the game server controls the creation, maintenance and changing of the voice conferences. Participation in a voice conference is determined by the game state features associated with each player including distance and direction to determine how the voices are mixed in a voice conference.
