The document discusses the concept of "Home Zone 2.0" as a solution for mobile operators to own voice services in the home. It involves using low-power access points like femtocells and Wi-Fi to provide improved coverage and offload traffic. UMA is identified as the 3GPP standard that can enable Home Zone 2.0 by addressing challenges of earlier cellular-based approaches and leveraging broadband connectivity. Major mobile operators are expected to trial femtocell solutions in 2008 and UMA dual-mode handsets are gaining widespread commercial availability.

3. Current Telecom “Battleground” Mobile Operators Fixed Operators VoIP Operators Who will own voice services in the home? “ Battle for the Building” Fixed-to-Mobile Substitution Fixed-to-VoIP Substitution Mobile-to-VoIP Substitution

4. The Mobile Operator’s Dilemma How to offer service differentiations Mobile Advantage: Common Service Experience across the network Mobile Dis-Advantage: Common Service Experience across the network Home Office Hot Spot

5. Home Zone Mobile Operator Approach for Owning the Home Home Zone Definition A service zone where operators can be aggressive on price Today, ‘Zone’ is defined by the cell towers surrounding the home Consumer demand is strong O2 DE – Genion Discounted calling when in ‘zone’ 74% of post paid subscribers take Genion, 3.94m subs. Voda DE – Zuhause 2.4m subscribers Operator objectives Accelerate FMS Reduce churn Cellular Home Zone (Based on Cell ID) Home Zone

13. Femtocell Market Update

14. 2007 Femtocell Market Summary Market consensus on approach: ‘Iu-based’ RAN Gateway ‘ Iu-b’ and SIP approaches too costly and limited UMA Position : UMA is the leading Iu-based implementation Lead operators enter lab trials Vodafone, O2/Telefonica, Telia, SFR, T-Mobile,… UMA Position : UMA solutions in trial at SEVEN major operators Industry recognizes need for core interface standard Key objective of Femto Forum 3GPP study items in progress UMA Position : Current 3GPP UMA/GAN standard meets requirements Only approach fully standardize-able in 2008

15. Femtocell-to-Core Network Connectivity Primary Implementation Options SIP-Based (a.k.a. IMS based) SIP Internet Security HSS SIP MSC E, D Iu-CS Iu-PS Internet RNC-Based (a.k.a. “Iu-b based”) Iu-b over IP RAN Gateway (a.k.a. “Iu based”) Internet Iu over IP RNC Existing Mobile Core Network (Circuit, Packet, IMS services) Security & Aggregation GW (SMS) GW (SMS) GW (SMS) Femtocell Femtocell RAN GW Femtocell Radio Management Functions Core I/F

16. Challenges to Femtocell Deployment Service offer Benefit today for operators Network Offload, coverage in-fill What drives consumers to take service? Today: Cheap Voice Need to expand into data Cost Need femtocells at $200 or less Driven by standards, in turn drive volumes Standards Time to standards = Time to Market UMA offers best option for femtocell standard in 2008 “ With a very conservative update of new innovative services enabled by femtocell solutions, it could take as much as five years before carriers go into the black on femtocell solutions .” Stuart Carlaw, February 2007 £ € $

17. 2008 UMA Femtocell Market Outlook The Race to Initial Deployments Most major operators will field trial femtocells 2008 For leaders: trials in 1H08 -> pilots in 2H08 UMA Position : UMA solutions ready to support, NOW The Race to Standards 3GPP initiates formal standardization UMA Position : Only approach standardize-able in 2008 NEC, Motorola, Kineto making joint submissions to 3GPP

18. Femtocell Announcements Europe The Race to Initial Deployments “ Kineto Ready to Support Commercial Femtocell Rollouts” Latest release meets operator requirements for full service deployment (Wed Feb 6) “ T-Mobile to Trial Ubiquisys Femtocell” Based on an investment in the company “ Vodafone to Trial Femtocells” Trialing both Alcatel/Lucent and Huawei “ O2 Announces Femtocell Trial” Based on NEC solution “ Telia Announces Femtocell Trial” Based on Motorola solution “ NEC Announces Trials of Femtocell Solutions” Announced trial activities and femtocell product portfolio “ Motorola Announces Family of Femtocell Access Points” 8000 is stand-alone femto, 8100 is home gateway + femto International

24. Conclusion

25. Strong Industry Recognition "We believe UMA will go down in history as the most important wireless industry phenomenon since the advent of GSM in 1992.“ "UMA, which was believed to have short legs just a year ago, is the predominant technology deployed today to implement seamless FMC between wireless LAN and 2G cellular networks. For those who still believe UMA will be short lived, it can now support 3G, is backed by the 3GPP, has a clear migration roadmap to IMS and is becoming the default case for femtocells .” Femtocell Dual-mode Handset Jim Ballsillie sees "unbelievable" potential in Wi-fi technology and UMA. This convergence, Balsillie said, is "incredibly positive to a carrier that thoughtfully embraces it."

26. UMA: The Platform for HZ2.0 Mobile operators NEED to “own the home” Start with low cost voice, expand into data services Cellular-based Home Zone solutions are limited Revenue leakage Margin squeeze No coverage improvement Voice only Home Zone 2.0 (HZ2.0) solutions happening today Low power access point in home (femto, Wi-Fi) Leverage broadband to lower costs Addresses voice and data applications UMA is the 3GPP standard for Home Zone 2.0
