Competition remains intense but rational. Strict profitability focus in Operators.
All Operators considering NGN deployment and have issued RFP/Tenders
NGN market in Asia provides a potential for a cumulative operator capex
opportunity of approx. $3.9B* over 2007-2010 and $0.9B* in 2008

What is NGN
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

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.
