NGN Concept
NGN is a concept for defining & deploying networks, which due to their
formal separation into different layers & planes and use of open
interfaces, offers service providers a platform which can evolve in a
step-by-step manner to create, deploy & manage innovative services.
NG Architecture : Service oriented, layered (transport, control,
application)
NG Services
: Converged (quad play- voice, data, video & mobility)
NG Access
: High speed (Broadband) IP based connectivity
(ADSL,VDSL, WiMax, Cable TV, FTTH)
NG Transport
: Ethernet, IP-MPLS, RPR, T-MPLS
NG Mobile
: 3G+, 4G
NG Internet
: IPv6
NG Interconnect : Capacity and Quality based
NG Licensing
: Unified, Converged

FMC-Business Drivers
Many households today have at least one cell phone.
In these households estimated 60% of long distance calls and 36% of local calls
take place on mobile phone at home (Yankee Group)
14% of users use cell phones as their primary line (Yankee Group)
Additional 26% of users are ready to switch as in-building coverage improves
Over 50% of users place mobile calls when they are at home or office
(Wireless Review)
WiFi exists or can be supported in both places
Traffic on mobile network has been increasing causing QoS problem and hence
subscribers’ churn
Pressure to reduce tariff for voice services
“Fixed” broadband availability is growing at a rapid pace - double digits in
CALL
most cases
FAILED
VoBB provides new revenue stream for Service Provider, and also
give a low cost alternative to carry mobile voice traffic
Leverage low fixed line asset cost to support the mobile voice application
PLEASE
TRY
AGAIN!
Users need to access services seamlessly regardless of their
location, active device or the network access method
Lower CAPEX, Lower OPEX, Higher coverage and quality
Colombo, Sri Lanka, 7-10 April 2009
11
Driving Forces
Consumers like mobile phones
And all of them are not using just for mobility
In >50% cases used for portability, not mobility.
Consumes demands low cost for voice
Broadband is getting widely deployed
Voice over broadband is not only new revenue stream for SP, but also
the low cost alternative to carry mobile voice traffic
Leverage low fixed line asset cost to provide the mobile voice
application
Lower CAPEX, Lower OPEX, Higher coverage and quality
=> Fix Mobility Convergence

With FMC, users can access the best available service whether they have
mobile coverage (e.g. GSM, CDMA),
Wi-Fi/fixed-line coverage (e.g. Wi-Fi SIP over broadband)
or a combination of both.

Solution fit for different Operators
MNO (e.g. Cingular, Sprint)
Improve the mobile coverage with low cost WiFi- Residential / Enterprise / Public
hotspot
Partner with Cable/Fixed Op to offer total package- Triple or Quadra-play
NGN Operator (e.g. Vonage)
Enhance their current offerings with mobile capability
Partner with MNO as whole sell (MVNO) or roaming
Integrated Service Provider (e.g. Brazil Telecom)
In-house Mobile and Fixed line operation
FMC allows them to use fixed line infrastructure to offer mobile service
The combined infrastructure provides lower OPEX ratio comparing with pure MNO
Cable Operators (e.g. GCI, Comcast)
Partner with MNO to offer FMC
Natural extension from Triple-play to Quadra-play – Voice, Data, TV/Video, Mobile
FMC-Enabler (e.g. VeriSign)
Host equipment and provide FMC backend capability to other NGN, MNO operators
Work with multiple small/tier 2/3 operators – Don’t acquire FMC subs directly

FMC Solution Advantage –
Service Provider Perspective
Converged service infrastructure by consolidating the voice services between the
fixed and mobile networks
Mobile coverage (GSM, CDMA) – Offering mobility, convenience and ubiquity
Wi-Fi SIP over broadband – Offer better quality, lower cost and feature rich capabilities
Enhancement of Service Quality
Stimulates the new service opportunities to increase ARPU
Capability to quickly include value added services - VMS, SMS, CRBT, FMFM, Centrex..
Provides the service differentiators and creates the service stickiness to lower the churn
rate
Reduction in CAPEX/OPEX
by offloading the traffic from cellular to WLAN and spending less on infrastructure
buildout
Single set of user credentials
Using GSM IMSI method authentication for both networks simplifying the user
management
System Reliability and Scalability backed by Real Deployment
Based on the proven NGN (mSwitch) platform (and its IP core)
The single mSwitch solution implementation serves over 2.1 m subscribers
Architecture compliant with 3G/IMS
Future-proof via open standards
Colombo, Sri Lanka, 7-10 April 2009
16
FMC Solution AdvantageUser Perspective
FMC enable users to access their voice and data services transparently,
regardless of their location, device, or network-access method
‘One Number’ and ‘One Phone’ service
WiFi SIP or GSM/CDMA coverage
The user will be able to initiate and terminate calls at any place
Seamless Roaming
The user will have non-interrupted call sessions when moving from one network to
another
Uniform and consistent service accessibility & behavior independent of
access
especially attractive for enterprise users to extend corporate VPN to cellular
networks.
Reduced monthly charges & convenience of a single bill
Simplified and Unified service plans and payment schemes.
A single always reachable phone number (Option for dual number)
Availability of new services
e.g. IM, Unified VM, SMS, Unified phone book, CRBT….

Service providers can now:
• Reduce churn by providing single number NGN & wireless service to customers
• Increase stickiness through advanced services
• Generate new revenue through supporting roaming agreements
• Future-proof via open standards
• Maintain a single cost-optimized network infrastructure

No Impact to Existing Networks
To Existing NGN Networks:
A functional module addition to the existing SoftSwitch and backend application
Able to use the existing NGN for call processing and routing
Normal NGN users are still served by existing infrastructure
Zero impact of the FS addition
All (home/visiting) FMC users will be served by the FMC-FS
Registration, authentication, roaming, call processing, handover
FMC-FS requires access to FMC user profile data
HSS (Home Subscriber Server) model of IMS
To Existing GSM Networks:
GSM Homed FMC users appear to be regular GSM users
NGN Homed FMC users appear to be visiting GSM users
FMC-FS uses standard roaming Interface to the GSM Network

PSTN to NGN Migration Case Study
Background
A leading tier 1 carrier in Philippine
Owning 2m fixed & 22m GSM mobile customers as of Q2 2006
A public company listed in NYSE
Total market cap of US$7.8B as of Sept 2006
Total revenue US$2.5B in last 4 quarters
EBITDA US$1.6B in last 4 quarters
Operating margin 37%
A fast growing service provider in Asia
Provides fixed line, GSM mobile and broadband data service to both residential and enterprise
customers
Problem Statement
How to sustain and grow the fixed line service?
Lots of population without telephone service
Lots of business users demand more service
How to increase the ARPU leveraging NGN/IMS?
IPTV? FMC? Triple-play? Quadrupled-Play?
How to lower the OPEX?
Real estate expense in the big metropolitan area?
Power consumption?
Human resource required for operation?
How to manage EOL/EOS of the aged TDM switches?
The cost of maintaining is unbalance with the cost of buying new

UTStarcom Solution
PSTN Emulation Subsystem – PES
Provide services to green-field customers
Replace the existing TDM switch – total 7 models in place
mSwitch as the core
SoftSwitch + Gateways + Backend office applications

Combination of DSL, DLC and VoIP AG
Foundation for FMC and IPTV in the future
Phase 1: Started with 150K NGN lines capacity
Network installation and migration planning for 3 months
First TDM switch replacement/migration in March 2006
Adding customer via both old switch migration and green
field expansion
Service extension to Centrex
Targeting under served enterprise customers
Phase 2: Network expansion to total of 500K NGN lines
Contract signed in later 2006
Network fully deployed
Phase 3: Planning for total of 1.5M NGN lines in 2008
Total 5m NGN lines planned in next 3 – 5 years
150+ CO sites replaced by 3 NGN SS sites
