SIGNAL-LINKING SERVER, SERVICE QUALITY PROVIDING SERVER, AND METHOD USING FLOW LABEL FOR PROVIDING MULTIMEDIA SERVICE IN IPV6 NETWORK

摘要

PROBLEM TO BE SOLVED: To provide a QoS provision method and a system that uses flow label for providing multimedia service in IPv6 network.;SOLUTION: The QoS provision method includes a step where a signal linking server extracts session information from call request response signal transferred from the destination and transfers to the QoS provision server; a step where the QoS provision server generates a session key, containing flow label and sets QoS information corresponding to the session key; a step where the QoS provision server transfers the session key and QoS information to IPv6 node and transfers QoS provision completion information to the signal-linking server; a step where the signal-linking server transfers the received call request response signal to the departure place, after receiving the QoS provision completion information; and a step where the IPv6 node forwards packet that is made to flow, based on the session key and the QoS information.;COPYRIGHT: (C)2007,JPO&INPIT
