Solution fit for different Operators
MNO (e.g. Cingular, Sprint)Improve the mobile coverage with low cost WiFi- Residential / Enterprise / Public hotspotPartner with Cable/Fixed Op to offer total package- Triple or Quadra-play
NGN Operator (e.g. Vonage)Enhance their current offerings with mobile capabilityPartner with MNO as whole sell (MVNO) or roaming
Integrated Service Provider (e.g. Brazil Telecom)In-house Mobile and Fixed line operationFMC allows them to use fixed line infrastructure to offer mobile serviceThe combined infrastructure provides lower OPEX ratio comparing with pure MNO
Cable Operators (e.g. GCI, Comcast)Partner with MNO to offer FMCNatural 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 operatorsWork 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 ubiquityWi-Fi SIP over broadband – Offer better quality, lower cost and feature rich capabilities
Enhancement of Service QualityStimulates the new service opportunities to increase ARPUCapability 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/OPEXby offloading the traffic from cellular to WLAN and spending less on infrastructure buildout
Single set of user credentialsUsing GSM IMSI method authentication for both networks simplifying the user management
System Reliability and Scalability backed by Real DeploymentBased 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/IMSFuture-proof via open standards

FMC Solution Advantage-User 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’ serviceWiFi SIP or GSM/CDMA coverage
The user will be able to initiate and terminate calls at any place
Seamless RoamingThe 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 billSimplified and Unified service plans and payment schemes. A single always reachable phone number (Option for dual number)
Availability of new servicese.g. IM, Unified VM, SMS, Unified phone book, CRBT….

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 routingNormal NGN users are still served by existing infrastructure
Zero impact of the FS additionAll (home/visiting) FMC users will be served by the FMC-FS
Registration, authentication, roaming, call processing, handoverFMC-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 usersNGN Homed FMC users appear to be visiting GSM usersFMC-FS uses standard roaming Interface to the GSM Network

iNumber is UTStarcom solution name for Find-Me-Follow-Me service
Subscriber registers one number as a master number
Then associates other numbers to the master number- home, office ...
Whenever the master number is called, the system will ring sequentially all the numbers
Flexible number bundling among SIP user, PSTN POTS, PLMN MSISDN etc.
Dial one number to reach all the bundled number
Support sequential and simultaneous ringing options

PSTN to NGN Migration Case StudyBackground
A leading tier 1 carrier in PhilippineOwning 2m fixed & 22m GSM mobile customers as of Q2 2006
A public company listed in NYSETotal market cap of US$7.8B as of Sept 2006Total revenue US$2.5B in last 4 quartersEBITDA US$1.6B in last 4 quartersOperating 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 StatementHow to sustain and grow the fixed line service?
Lots of population without telephone serviceLots 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 SolutionPSTN Emulation Subsystem – PES
Provide services to green-field customersReplace the existing TDM switch – total 7 models in place
mSwitch as the core SoftSwitch + Gateways + Backend office applications
iAN8000 as the accessCombination of DSL, DLC and VoIP AG
Foundation for FMC and IPTV in the future
Phase 1: Started with 150K NGN lines capacityNetwork installation and migration planning for 3 monthsFirst TDM switch replacement/migration in March 2006 Adding customer via both old switch migration and green field expansion
Service extension to CentrexTargeting under served enterprise customers
Phase 2: Network expansion to total of 500K NGN linesContract signed in later 2006Network fully deployed
Phase 3: Planning for total of 1.5M NGN lines in 2008 Total 5m NGN lines planned in next 3 – 5 years150+ CO sites replaced by 3 NGN SS sites

Blueprint of One Real CO Space Reduction
19 x 11 =209ft2
6 x 4 =24 ft2
48 x 29 =1392 ft2
6 x 34 =204 ft2
Total Space= 1392+209+24= 1625 ft2
Total Saving in One CO =1421 ft2

Greatest Experience: Cut-Over Procedure
IP, NGN, and PSTN inter-connect infrastructure configured and tested
AGs installed, wired on MDF, configured, and qualified
Migration of Digital Loop Carriers Retrofitting the access gateways in existing DLC cabinet
Consolidation of cabinet areas
Sample subscriber data populated, provision ADSL Sub
Number migration set up and tested for lines and trunks
Bulk sub data migrated and tested again for all features and billing
MDF- isolation pin switched so that sub lines are switched from legacy switch to AGs (a couple of minutes)
PSTN tandem switches re-route traffic from legacy switch to NGN C4 (1 minute)
