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


11

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

Migration Benefits

CAPEX SavingsCentral Office (CO) consolidationSimpler network with fewer types and pieces of equipment

OPEX Cost Savings- 80%Operation and Maintenance cost reduction

Reduced power consumption- 94% (Reduced air-conditioning requirements)Faster provisioning of services

Floor Space Savings- 92%Reduced space requirementsConsolidation of cabinet areas

Improvement in “time-to-market” for new services- 90%Faster introduction of new services Increase in Revenues

EOL managementEnd of support to critical TDM components- High cost of vendor supportStop manufacturing of componentsSalvage components to support in-house repair of modules when they run out of spares.

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


14

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)
