IMS Motivation, Drivers and Opportunities (3) –
Key IMS Functions and Benefits
 Increase control and profitability through
a common IMS based Service Infrastructure:

The IMS is an open Service Infrastructure providing Service Support Functions that
assist the development/control/integration of services.
IMS is not just a simple SIP-Proxy.

IMS Motivation, Drivers and Opportunities (5) –
Siemens IMS Strategy: IMS based Service Consolidation
 One IMS based Service Infrastructure for: 1) Fixed Market, 2) Mobile
Market, 3) (Hosted) Enterprise Market, 4) Transit/Interconnect Market
will provide a Converged Communication World.

IMS as central core in 3GPP (Mobile, WLAN), TISPAN (Fixed), PacketCable2.0 (Cable)
ensures interoperability and long term investment protection.

Siemens FMC Reference
Time Warner Cable demonstrates dual mode telephony
Solution concept
München, Stamford, Connecticut,
May 2, 2006
Siemens Communications and Time Warner Cable
recently showcased fully integrated fixed line, mobile
and WiFi broadband technologies via the IP Multimedia
Subsystem (IMS) designed to deliver fixed mobile
convergence (FMC). The demonstrations, which
recently took place at Time Warner’s U.S. facility,
highlighted the practical value for network operators of
adopting Siemens’ IMS solutions and also showed how
consumers can enjoy shared multimedia applications,
entertainment features and communication sessions –
all on the basis of converged solutions.
…
The technical platform for simple network handover
and the provision of multimedia services is the
Siemens IP Multimedia Subsystem (IMS@vantage).
…
Time Warner, one of the first cable network providers
worldwide to demonstrate IMS, plans to use Siemens
technology commercially to support a wide range of
IP-based services.

Network operators may chose a
stepwise introduction of FMC
Fixed
Step 1
• Gain experience
• Enable network for FMC service delivery
Step 2
• Early time-to-market with FMC services
• Full reuse of equipment
• Add few additional components for FMC
Mobile
Deploy VoIP / NGN
applications
in fixed nets
Deploy IMS
applications
in mobile nets
Add e.g. multiple terminal access to fixed network offer,
add 2G/3G inter-working for video and data applications,
add fixed-wireless access (e.g. WLAN), ...
Step 3
Single Brand
• Address both fixed and mobile market
with complete FMC offering
for bundled fixed & mobile FMC services
Operators that already deploy NGN in fixed, or IMS in mobile networks
today are expected to be first to offer Fixed Mobile Converged services
