  3. Business Goals Subscriber Generated Growth While Reducing Costs • Remove Silos • Accelerate Service Rollout • Increase Subscriber Revenue • Increased ARPU • Increased Stickiness • Beat Competition

  4. FMC Mobility - Seamless Roaming Single Access-Agnostic Backbone Single Location-Agnostic Backbone Services Single Service-Agnostic Backbone Multi-Service Service Blending IP Enhancements Security End-to-End QOS Charging/Billing Architectural Goals Value Services = More than a Bit-Pipe Carrier

  5. Personalization Location-Aware, Time-Aware, Availability-Aware User-Controlled Policies and Account Profiles Unification Terminals Applications Socialization VoIP Blended Services (Presence, IM) Ad-Hoc Social Networking Automation Contextual Text Messaging Contextual Advertising Enhanced Customer Experience Customer Experience The number of worldwide mobile connections is expected to grow 50%from 2.7 billion in 2006 to 4 billion in 2010. Wireless Intelligence

  6. IMS Architecture – Service Delivery Architecture

  7. IMS Market Maturity, Demand Drivers and Risk Factors

  8. Global Service Revenue

  9. Growth in IMS Systems Revenue Globally

  10. Integrate different access networks into common evolving IP, Pre-IMS, IMS, or NGN core network Allow authenticated subscribers access to authorized services from any location/network Deliver End-to-End Per-Flow QoS Terminate Secure Tunnels + Encrypt/Decrypt Fraud Prevention - Prevent Theft of Bandwidth and Services Provide DOS Protection to UE and the network Serve Lawful Intercept Control, Media, and Data NAT for Public <-> Private Addressing Seamless Mobile IP Roaming IMS Services Goals Guaranteed Seamless Multi-Service Delivery To Mobile and Fixed-Line Subscribers

  11. Operator Challenges to Implementing IMS Vendors/Product Availability Internal business processes Interoperability Interfaces from infrastructure to applications Integration with legacy networks Interconnect agreements

  12. Security • SIP, RTSP, RTP, and HTTP Application Layer Attack Layers • TCP and UDP • IP and ICMP Transport Layer Network Layer • Malformed packets • Floods • DoS attacks • Hijacking • Unauthorized access • Theft of service • Theft of bandwidth Revenue Attacks DoS Attacks • Mutual Authentication • IPSec or TLS Encrypted Signaling • IPSec Encrypted Bearer Data Secure Access
