Patent ID: 8239468

Claim:
A session Quality of Service (QoS) control apparatus, configured to relay control information for a user session between a first user communication terminal and a second user communication terminal, the session QoS control apparatus comprising: one or more processors; a session information analysis unit including at least one processor of said one or more processors, and configured to analyze a session state of the first user communication terminal by referring to user session information received from the first user communication terminal, and by referring to: a session management database configured to store session management information for the user session between the first user communication terminal and the second user communication terminal, and a user preference database configured to store user preference information representing a user QoS requirement associated with the first user communication terminal; a session QoS control unit including at least one processor of said one or more processors, and configured to determine a QoS policy for the user session, based on the result of session state analysis performed by the session information analysis unit, to generate a session QoS command addressed to a router configured to set the QoS policy, wherein the router configured to set the QoS policy is identified by referring to: a router management database configured to store a mapping of a connection between the first user communication terminal and the router; and a unit for communication with the router, configured to transmit to the router the session QoS command generated by the session QoS control unit.
