Objectives

• Demonstrate how in a very short time IMS has
  moved from a standard/theory to actual
  applications
• Update on trials, applications, where IMS fits
  with convergence, key learnings
• Key Finding in various markets
• Japanese priorities vs North America vs European
• Key learnings and pitfalls

Trial Observations

• Japan is ahead of all other markets
• Europe is ahead of N. America
• CALA just starting to get up to speed on IMS

6
Trial Observations

• We are in multiple trials and some deployments
• 12 trials, 5 deployments
• MRFC and MRFP function and multiple applications
  have been IMS certified
• Trials have validated our roadmap on Applications
  UM, Conferencing moving to Video
• No killer application seamless user experience
  across networks, access and services promises
  convenience, and carrier savings
• QOS and Security becoming the major operational
  issues
• Softswitch vendors are still the anchor component
  
• Integration and Interop issues are slowing
  deployments

Learnings from Trials and Deployments

• Here are the milestones met in the trials
• Key applications including Voice Mail, Unified
  Messaging, Conferencing, Privacy Screening, Find
  Me Follow Me in addition to our Mereon 6000 Media
  Server have been IMS certified by the trial
  carriers
• In 2006, it has moved from trial to deployment
  with 5 Tier One carriers
• These trials started in 2005, giving added
  momentum to our already ambitious IMS plans
• Video, Security, Resiliency have proven to be
  critical for success in these trials

Challenges to IMS deployment

• HSS deployments
• Consolidation of the major players
• New models in rapid application deployment
• Web based applications
• Microsoft enterprise ambitions
• FMC with WiFi/WiMax
• Inertia
