Worldwide estimates and forecasts of IMS infrastructure
(In millions of dollars)
 New research from Venture Development Corp. estimates worldwide markets for IP multimedia
Subsystem (IMS) infrastructure equipment will exceed $2.6 billion by 2008.
 This represents a compound annual growth rate of 67% from 2005 to 2008.
 Key infrastructure products in the market include application servers, home subscriber servers,
IMS softswitches and media resource function products.

IMS Rollouts Vary With Carrier Type
Distinct types of operators will leverage IMS differently in the coming five years

November 2005, Trends “IMS Will Transform Telecom”
IMS' Impact Varies With Carrier Type
>
2005 to 2007: Point deployments for Mobile operators dominate.
Wireless carriers will be the first to deploy IMS infrastructure because mobile standards will be stable. They
will focus initially on revenue-generating applications, like push-to-talk over cellular (POC) and voice-animated
picture sharing. Fixed operators like SBC will prepare for an IMS infrastructure upgrade (e.g., by consolidating
subscriber profiles within the HSS). Converged operators that want FMC will be more aggressive than wireline
providers. For example, BT's 21st Century Network plans rely on IMS, and today, BT uses IMS-compliant
Unlicensed Mobile Access to tie mobile and wireline networks together in its Fusion service. While BT is not a
true converged carrier in that it does not have a mobile arm, it is marching toward FMC with Bluetooth and
WLAN wireless. BT announced the world's first fully integrated fixed and mobile telephony service — BT
Fusion.
>
2007 to 2009: Fixed carriers get serious.
As fixed standards stabilize in late 2007, fixed line rollouts will ramp up. Fixed-line carriers will use IMS to
power VoIP offerings and new combinational applications like voice/Web session integration for contact
centers. Mobile operators will progress to a full IMS-powered network, enabling true VoIP over cellular. As
VoIP erodes mobile voice ARPU, wireless carriers will turn to new combined voice/data applications like
locator games with voiceover hints, to compensate for the voice revenue decline. Converged carriers will offer
applications that work seamlessly across networks, like an active phone book that provides presence and
bridges communications across all network types, whetting customers' appetites for continuous connectivity.
>
2009 and beyond: IMS becomes a core part of network architectures.
By 2009, customers will begin to expect applications to work continuously across all types of wireless and
wireline networks. As a result, FMC will help generate revenue and cement customer loyalty as carriers offer
single contact number and presence across multiple networks. Geographically, this plays out differently. In the
US, Verizon and Verizon Wireless will use IMS to link their networks and enable them to capitalize on FMC. In
Europe, converged mobile/fixed network leaders like FT and Telecom Italia will grow market share at the
expense of late movers lacking a converged offering.
