Session 2 Evolution And Outlook

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?

IMS Research What do those slides tell us?

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%

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

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 IMS Evolution and Outlook

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?

IMS Evolution and Outlook When can we expect to see penetration of IMS services? Not yet!

IMS Evolution and Outlook When can we expect to see penetration of IMS handsets? Not yet!

IMS Evolution and Outlook Decomposed model has advantages Scale Vendor independence Ease of upgrade and migration But challenges for interoperability Protocols are great! Why?

IMS Evolution and Outlook REF: Quick Scan IMS Vendors, TNO Report November 2007 Causes of Interoperability Issues

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

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”

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

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
