A dem<strong>and</strong>ing market reality <strong>for</strong> service providers…<br />
Falling revenue from voice services …<br />
competition from alternative communication<br />
means (VoIP, churning to mobile, IM, etc)<br />
Cost Challenge<br />
Traffic<br />
Aging TDM voice switches …<br />
High maintenance cost<br />
Revenues<br />
… <strong>and</strong> users expect more<br />
Simple, innovative, personalized communication<br />
across any device, any network, anytime,<br />
anywhere<br />
Mainly<br />
voice<br />
Multimedia/multiservice<br />
Time<br />
Requires a change from keeping value in the network to<br />
extracting value from the network<br />

What is the operator’s strategy ?<br />
Alternative 1<br />
• Continue legacy<br />
Alternative 2<br />
• Trans<strong>for</strong>m but don’t evolve<br />
Alternate 3<br />
• Trans<strong>for</strong>m <strong>and</strong> Evolve<br />
10 | Migration to a HLN All Rights Reserved © Alcatel-Lucent 2010
Investment Strategy<br />
Objective<br />
• Invest in the most future proof<br />
technology possible in the context of<br />
asset lives <strong>and</strong> revenues possible<br />
• Deploy Converged Core <strong>for</strong> all types of<br />
access network<br />
Strategy<br />
• Invest in one-step approach instead of<br />
two step approach<br />
• Use IMS <strong>for</strong> access agnostic core<br />
• Use service control layer to enable<br />
subscribers enjoy similar “user<br />
experience” across domains<br />
• Deploy IMS which makes FMC possible<br />
• Invest <strong>for</strong> ease of operations cost<br />
• All-IP network <strong>and</strong> common core<br />
reduces the OPEX costs<br />

• <strong>Operators</strong> in emerging<br />
markets are still<br />
experiencing line growth<br />
• There are benefits to<br />
investing in IP, rather than<br />
circuit-based technology<br />
(e.g., new services)<br />
• Markets with line growth<br />
include Africa, the Middle<br />
East, the Commonwealth of<br />
Independent States (CIS),<br />
<strong>and</strong> areas in Asia-Pacific<br />

Replacement<br />
• Some operators are<br />
considering replacing their<br />
TDM Class 5 switches with<br />
IP-based technology<br />
• The goal of this<br />
replacement is primarily<br />
<strong>for</strong> operational savings<br />
• Service providers who<br />
have advertised this<br />
strategy include BT <strong>and</strong> DT<br />

investing in an overlay<br />

• End-users can be enticed to<br />
move their voice to the<br />

of bundles with data <strong>and</strong><br />
