Abstract:
A user equipment (UE) device (11) including a mobile terminal (MT) (11b 11bâ€²) coupled to a terminal equipment (TE) device (11a), for use in multimedia communication requests for internet protocol (IP) communications across a packet switched communication network (12) where the multimedia communication requests are made using signaling according to a predetermined protocol, the TE (11b) including a user agent (UATE) for providing a communication establishment message (INVITE) as part of the signaling and including a session description protocol (SDP) component, the UE device (11) characterized by:a) an IMS proxy adjunct (P+), located in the TE device (11a), responsive to the communication establishment message (INVITE) and other messages including the SDP component, for making extensions to the communication establishment message (INVITE) and other messages by extending the SDP component so as to reserve resources ensuring a predetermined quality of service (QoS) for the IP communications, and for originating and terminating messages according to the predetermined protocol on behalf of the user agent (UATE) in the TE device (11a) so that the packet switched communication network (12) need not take into account the operation of the IMS proxy adjunct (P+); and b) an IP router and QoS manager (Q), located in the MT (11b 11bâ€²), responsive to control signals provided by the IMS proxy adjunct (P+), for providing QoS using access network specific procedures to open QoS enabled IP flows, and routing IP packets to different QoS enabled IP flows.
