Transcript

  • 1.  
  • 2. IMS Evolution and Outlook
    • Some misconceptions
    • What will operators do with IMS (vendors perspective)?
    • Revenue Expectations
    • How does IMS align with new initiatives?
      • Web 2.0
    • What are the opportunities for IMS?
    • What is the overall outlook?
  • 3. IMS Research REF: AMF Ventures, http://www.slideshare.net/tonyfish/amf-ventures-survey-results
  • 4. IMS Research REF: AMF Ventures, http://www.slideshare.net/tonyfish/amf-ventures-survey-results
  • 5. IMS Research
    • What do those slides tell us?
  • 6. IMS Research
    • Slide A:
      • Very important: 25%+
      • Important: 42%+
      • Moderately important: 20%
        •   VI + I = 67%
        • VI + I + MI = 87% 
    • Slide B:
      • VI: 13%
      • I: 39%
      • MI: 32% 
        • VI + I = 52%
        • VI + I + MI = 84%
  • 7. IMS Research
    • Results are actually strikingly similar
    • Tony Fish:
      • “ the differences were often quite subtle. It made it hard to pull out any real differences between each question”
      • “ You caught a slide where we got the phrasing backwards”
    • IMS provides just the QoS framework demanded
  • 8. IMS Revenue Expectations REF: Pyramid Research, IMS Market Opportunities, April 2008
  • 9. IMS Evolution and Outlook REF: Quick Scan IMS Vendors, TNO Report November 2007
  • 10. IMS Evolution and Outlook
    • IMS and Web 2.0
    • Complementary, not competitive
    • IMS provides real time telco capabilities
      • Convergence on network layer
      • Policy admission and control
      • Extensible framework for adding and abstracting capabilities
    • Web 2.0 leverages capabilities from multiple resources to create mash-ups and interactive services
    • Examples

    • IMS and SOA
      • Service Orientated Architecture
      • Abstracts system functions into services
      • Integrates services into applications
      • Defines services as:
        • Logical representation of a business function
        • Self contained
        • Possibly composed of other services
        • “ Black box” to consumers of the service

  • 25. IMS Evolution and Outlook
    • IMS services
      • “ An IMS service is a service that makes use of SIP and the IMS either centrally or marginally”
        • Christophe Gourraud, IMS Lantern
        • http://theimslantern.blogspot.com/2008/01/what-is-ims-service.html
      • How many can we expect to see?
  • 26. IMS Evolution and Outlook REF: Quick Scan IMS Vendors, TNO Report November 2007
  • 27. IMS Evolution and Outlook
    • When can we expect to see penetration of IMS services?
      • Not yet!
  • 28. IMS Evolution and Outlook REF: Quick Scan IMS Vendors, TNO Report November 2007
  • 29. IMS Evolution and Outlook
    • When can we expect to see penetration of IMS handsets?
      • Not yet!
  • 30. IMS Evolution and Outlook REF: Quick Scan IMS Vendors, TNO Report November 2007
  • 31. IMS Evolution and Outlook
    • Decomposed model has advantages
      • Scale
      • Vendor independence
      • Ease of upgrade and migration
    • But challenges for interoperability
      • Protocols are great!
    • Why?
  • 32. IMS Evolution and Outlook REF: Quick Scan IMS Vendors, TNO Report November 2007 Multi Vendor Interoperability of IMS Functions
  • 33. IMS Evolution and Outlook REF: Quick Scan IMS Vendors, TNO Report November 2007 Causes of Interoperability Issues
  • 34. IMS Evolution and Outlook
    • Considerable debate about role of IMS
      • Is it too bloated?
      • Can it deliver?
      • Can alternatives serve just as well?
    • General consensus is that real time services need IMS and that it will happen
      • Despite problems and credible alternatives for some operators
      • Evolution not revolution
  • 35. IMS Evolution and Outlook
    • . "In the wireline community, deployment on a massive scale is still likely to take place around the Tispan elaboration of IMS, as incumbents make the transition to VOIP and a suite of related communications-oriented services. Misgivings about IMS are greater on the wireless side, yet with few obvious alternatives today, wireless telcos are also likely to deploy IMS on a wide scale.“
      • Graham Finnie, Chief Analyst, Light Reading and author of “ IMS Deployment Update: Promise & Challenges”
  • 36. IMS Evolution and Outlook
  • 37. IMS Evolution and Outlook
    • Near / medium term
      • IMS deployments proceed piecemeal, except in largest telcos
      • Adopting NGN means facing up to IMS at some point
        • Cbeyond may be right in their case, but they are an alt net with 33K subs (Q3 07)
          • Not a tier 1 with multiple networks
      • Solid business cases can be derived for certain services, targeted at certain segments
    • Long term
      • IMS will proliferate
      • Long tail will be enabled and enriched by Web 2.0, via open gardens and exposure of service enablers and capabilities

    • Multiple services create business case
      • >3
    • Paradox of stovepipes
      • Deploy initial service to kick-start activity
      • Adding services gets cheaper and easier
    • Little debate that IMS is a key enabler for SDPs

  • 44. IMS Evolution and Outlook
    • Finally….IMS Lantern:
      • IMS core is merely route to connectivity to enablers and user access devices
      • Provides sophisticated SIP routing and security
      • Focus should be on applications and the ability to access users and resources
      • Doesn’t undermine IMS, merely suggests focus and emphasis away from complexity of core components
      • If IMS is the best way to provide this, it will create its own business case and succeed
    • My view – nothing else provides the interoperability and scale that may be required to achieve this consistently across all domains…yet
