The Business Challenges

• The successful carrier will have to
• Grow and protect subscriber base, increase ARPU
• Deliver a differentiated portfolio of value-added
  services
• Maximize ROI while controlling OPEX
• Invest in open systems, standards-based solutions
  to remain competitive
• Enhance capabilities of legacy systems if
  necessary
• Focus on application services
• Rapidly develop and deploy new services,
  including video
• Develop on standards-based technology
• Reduce time to market for new applications using
  web development model

Lets Talk Services

• Applications deliver Services
• Services are a set of capabilities offered to
  customers
• Must be able to bill for services

and many more

IMS Building the Foundation

• Converged Application Service Architecture
• Separate Transport, Service Control and
  Applications Layers
• Fixed-Mobile Convergence on One Common IP
  Application Services Architecture
• Open, Standards-based
• Standards-based Protocol Interfaces (SIPXML) for
  Flexible Integration Control of New Services
• Not APIs that Bind to Operating System, Device
  Control Development Model
• Facilitates Service Creation Environment

IMS is all about applications, built on IP and SIP

IMS Simplified Network View

• Converged Applications
• Across Networks
• Reduced development costs and time
• Voice, Video and data services
• Write once / use many

Applications
Web Content

• Shared Resources
• Media server resources
• Common user data
• Single user profile across applications
• Integrated applications

Call Session/Control
SIP
Transport

• Session Control
• Common Session Control (SIP)
• Provides common service policies
• Leverages investments across multiple
• applications

Access Network

• Access Network Agnostic
• Eliminates multiple service solutions
• Network transparency
• Consistent services across networks

DSL
PSTN
Mobile
CMTS

Why IMS

• IP will continue to be a disruptive technology to
  traditional telecom operators and is transforming
  business models from voice-driven to
  service-driven
• Facilitates cap and grow approach
• Operators require more applications to meet
  competitive threats
• CAPEX and OPEX pressures are constant
• Operators need a better environment for creating
  and deploying high value rich multimedia services
• Service delivery velocity
• Lower cost standards-based platforms
• Controllable, yet open environment for service
  creation delivery

IMS Benefits

• Efficient Resource Utilization
• Standard interfaces allow multi-network
  interoperability for user to user interactions
  and content distribution
• Access Network Independence
• Content storage medium can be off line processed
  into various formats
• Shared Resources
• Lower Development Cost and Faster Deployment
• Modern, Proven Development Techniques
• Less Lines of Code to Write, Less Complex Code
  Less Errors
• Environment That is Familiar to Large Developer
  Pool (HTTP, HTML, and XML, etc)
• Off the shelf hardware software available from
  a more general development pool
