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 />

• 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 />
