SYSTEM AND METHOD FOR COMMUNICATING MUTI-USER IN ACCESS GRID THEREOF

摘要

A multilateral communication system in an AG(Access Grid) and a method thereof are provided to realize a user invitation function and various additional functions required for the invitation function through a message processing procedure, thus various additional services are available. A venue server(120) transmits/receives media data by connecting a origination client(100) to/from a destination client(110), and controls the overall conference for a video conference. A location DB server(130) receives URI(Uniform Resource Locator) and IP(Internet Protocol) addresses of the origination/destination clients(100,110), and stores the received addresses. A redirect module receives a registration message from the origination client(100) to transmit the URI and IP addresses to the server(130), and transmits a URI included in an invitation message to the server(130) if the invitation message is received, so as to receive searched result information of an identical IP address.
