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?

• 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 Revenue Expectations

• 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 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?

• When can we expect to see penetration of IMS services?– Not yet!




• When can we expect to see penetration of IMS handsets?– Not yet!




• Decomposed model has advantages– Scale– Vendor independence– Ease of upgrade and migration

• But challenges for interoperability– Protocols are great!

• Why?



Multi Vendor Interoperability of IMS Functions



Causes of Interoperability Issues


• 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


• . "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”



• 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


REF: Motoshi Tamura, NTT DoCoMo, IMS World Forum, 2008



• 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– IMS World Forum

• 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
