Patent ID: 8023979

Claim:
A method, by a server, for separating a session according to an attribute of media to transmit the media, the server connecting to at least one terminal through a Session Initiation Protocol/Internet Protocol (SIP/IP) core network, the method comprising the steps of: receiving a session establishment parameter for pre-setting an attribute of media on a multimedia session from arbitrary terminals; setting the session establishment parameter for each of the arbitrary terminals; receiving a multimedia session INVITE message from at least one requesting terminal, the multimedia session INVITE message including at least one attribute of media; extracting the attribute of media in the multimedia session INVITE message for splitting the arbitrary terminals according to the extracted attribute of media; comparing the extracted attribute of media with the set attribute of media for the arbitrary terminals; applying service settings to the arbitrary terminals corresponding to the INVITE message to establish a session with each of the arbitrary terminals based on the respective set attribute of media corresponding to each of the arbitrary terminals as a result of the comparison; splitting the multimedia session INVITE message to be transmitted to the arbitrary terminals based on the respective set attribute of media corresponding to each of the arbitrary terminals; and establishing a session with each of the arbitrary terminals by transmitting the split INVITE messages to corresponding routing addresses according to each of the arbitrary terminals.
