(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) 20 © 2004 Nortel 10 Nortel Corporate Presentation Some sample IMS in NGN scenarios 21 What does this mean for the Core Network? > Common, access independent NGN Core Network solution: IP-based using IETF protocols > Basic mobile telecommunications paradigm includes integration of IMT-2000 (3G) and Wireless LANs > Common issues dealt with in a common way: • • • • • QoS Fraud/Privacy CS (legacy) interworking Charging ... 22 © 2004 Nortel 11 Nortel Corporate Presentation NGN - Convergence Model > What’s new: horizontally integrated network Video Services (TV, movie, etc.) Data Services (WWW, e-mail, etc.) Telephone Services NGN Services Point to point, point to multipoint, multipoint to multipoint NGN Transport Point to point, point to multipoint, multipoint to multipoint ITU-T Recommendation Y.2011 23 3GPP R5 network architecture Signalling This animated chart is & Control provided as two Bearer discrete charts at the Roaming end of this package.
