10 What is IMS? (1/2) > IP Multimedia Subsystem A set of core network functional entities to support access to operator provided SIP based services. > Builds on IETF protocols to create a robust and complete multi-media system SIP, SDP, DIAMETER Enhancements, operational profiles provide support for operator control, charging and billing, and security 19 What is IMS? (2/2) > Vertical interfaces to transport level provide: Coordinated assured QoS (session layer negotiation matches resources at transport layer) Media gating under operator control Correlated accounting among service, session and transport layers > Coordinated network interfaces provide: Better user service experience: QoS, accounting, single sign-on, better security, etc. Common Application Server interfaces for: Accounting/charging, security, subscriber data Service building blocks (e.g., for Presence, Location) Nortel 10
