  1. 3G Roaming Roll Out Challenges Siddhartha Kohli Regional Vice-President Asia Pacific

  2. Agenda • Roaming at a Glance • 3G & 4G Challenges • The Hubbing Concept • The IPX Factory • Achieving Ubiquituous Connectivity

  3. Roaming at a Glance

  4. Ubiquitous Roaming… • 2.4+ Bio GSM Users in 210+ Countries Around the World • 680+ GSM Networks Live • Roaming Mainly Achieved via Bi-lateral Agreements • Only 1 Roaming Partner per Country for Outbound Coverage • Between 200 & 400 Roaming Partners per Mobile Operator • Extensive Testing and Multi-Years Process • Existing Issues • New Mobile Operators with Small Subscriber Base Having to Roll Out Worldwide Roaming • Large Operators with Limited Resources and Focus on Cost Reduction • New Agreements and Implementations Required to Follow Services and Technologies Evolution (GPRS, 3G, CAMEL…)

  5. Closed Policy to Prevent Fraud & Spam Focus on Coverage for New Services Mature Market Tier 1 Mature Market Tier 2/3 Dvlp Market Tier1 Dvlp Market Tier 2/3 New Entrant Willing to Sign Roaming/IW Agreements Limited Volumes to Justify Expansion Universal Services, Not Islands… MNO MNO MNO MNO

  6. Fraud Agreements Deployment Support Billing Mobile Operators Challenges Enhance Service Offering & Extend the Reach

  7. Financials Aspects • Supporting Roaming through Bi-lateral Agreements • Average Setup Cost Per Service (Network & Billing) • Yearly Maintenance Cost (Commercial, Network & Billing) Estimated Cost Above 3 Mio EUR to Setup Worldwide Roaming

  8. 3G & 4G Challenges

  9. Enhancing the Interco Fabric • 1 Agreement with the Hub (AA14) • 1 Technical Connection • 1 Financial Relation • 1 Testing per Service Multilateral HUB Non-Roaming/IW Partners Bilaterals Roaming/IW Partners

  13. The Hubbing Concept

  14. GSMA Open Connectivity • GSMA Initiative Reviewing Current Bilateral Paradigm • One-to-One Needs to Be Replaced by a Many-to-Many Model • Global Roaming • To ensure that an operator is able to allow its customers to roam on the network of any other GSMA member • Global Inter-Working • To ensure that the customers of all 3GSM networks (and in future, other technologies) can send and receive services between themselves • Optimization of Costs • To ensure cost-optimization for operators in establishing and maintaining global roaming & inter-working agreements

  15. OC High Level Requirements(1/2) • Open Solution Interoperability of solutions • Obligation Manage white & black lists • Transparency Full visibility of transactions at commercial & technical level • Cascade Billing Remove need for bi-lateral settlement • Efficiency Efficient use of resources and minimize network configuration • End-to-End Quality of Service Measurement of KPIs and commitment on QoS (SLAs)

  16. OC High Level Requirements(2/2) • Service Support Full outsourcing capabilities for O&M activities • Testing Outsourcing of testing activities • One Relationship Need to offer One Stop Shopping solution • Fraud & Security Latest tools & functionality for anti-spamming & anti-fraud • Availability Continuous & reliable access to the service • Service & Enabler Support Offer services individually through a single connection

  17. MNO MNO MNO B MNO A Hub 1 Hub 2 Hub 3 MNO MNO • Single investment • Unique billing & settlement • Open competition • Trusted environment • Extended 2-way reach • Termination Revenue • Limited implementation • Reduced testing Next trial phase planned for Q1 2008 Open Connectivity Status Commercial and Technical framework for Hubbing Proof of Concept SMSsuccessfully demonstrated in Barcelona 3GSM World Congress 02/2006 (Orange, SFR, TI & Belgacom ICS) SMS Hubbing Trialcompleted with 13 hub providers & 29 Mobile Operators and announced at Singapore 3GSM Congress 11/2006 Proof of Concept Roamingsuccessfully demonstrated with Belgacom ICS in Barcelona 3GSM World Congress 02/2007

  18. The IPX Factory

  19. PSTN 3GPP VoIP/DSL PSTN Mobile TDM IP6 IP PSTN VoIP DSL PSTN GRX VoIP The Interconnect Roadmap TDM Only Switch MMS SMS IP on the Edge SoftSwitch Internet All IP E2E SIP/IMS Proxy IPv6 IPv4

  20. From Bit Pipe to Service Aware Network

  21. IPX IPX IPX IPX Towards an All-IP Universe MNOs ISPs Operators in Country A FixedLine ASPs FixedLine Multilateral Direct Bilateral Bilateral

  22. Operators Operators Operators GRX Evolution to IPX • IPX Re-Uses and Builds on GRX Functionality • IPX Proxy Already Tested in GSMA SIP Trials Program • GRX Providers Can Upgrade to an IPX • New Entrants Can Implement an IPX • Transit Networks Can Adopt IP Technology Operators Operators IPX Operators

  23. Achieving Ubiquituous Connectivity

  24. Implementing Hubbing… • SMS Inter-Working Through Multilateral Launched Early 2000 • Mainly used within North America, Latin America, Asia and Africa • 400 Networks already connected • Most of traffic flowing through IP connections (North America) • Limited traffic flowing between Multilateral islands • Final Open Connectivity SMS Recommendations Approved in 04/2007 • Enhancement Required of Existing Multilateral Solutions & Launch of New Hubs • SS7 and SMPP support • Cascade Accounting • Interoperability of solutions • Transparency • Initial SMS Hubbing OC Peering Announced in Q1 2007

  25. … For Seamless Inter-Working • Additional Interconnection Amongst Hubs to Be Added • Mobile Operators to Adopt the Hubbing Model and Enable Inter-Working via Hubs • Process to Be Formalized Between Mobile Operators and Hubs and Between Hubs for the Opening of Relations

  26. Q & A
