1 Summary of TSG-S Femto Related Activities Nick Yamasaki (KDDI) - Chair New Orleans, LA, USA March 31, 2009

2 Overview Femto Cell related standardization started in early 2007 – Work Item initiated in May 2007 sponsored by several companies Technical activities started in TSG-S in mid-2007 – TSG-S sponsored comprehensive 2-day femto cell workshop October 2007 in Boston was a foundation for very active inter-TSG effort – System requirements (SRD) development was engaging and fruitful – High level security aspect requirements included in SRD – Much thought given to OAM&P aspects in SRD – self-configuration Throughout 2008 extensive work has been done in all areas – SRD completed and published May 2008 – Security Framework work started - expected completion 3Q09 – Network Architecture Model work started – Vision – includes a section charting new directions for femto cells

3 Project Planning, Architecture, Security Work Items supporting Femto Cell Specification Development WI 00189: System Enhancements for Femto and Pico Cell Support WI WI 00215: Femto Security Framework WI Architecture and OAM&P Specifications Development Plans S.R0135-0, Network Architecture Model (NAM) for cdma2000 Femto-Cell Enabled Systems, projected completion 3Q09 S.R – Defines network elements and interfaces for femto cell systems S.S0028-E, OAM&P for cdma2000, projected completion 1Q10 S.S0028-E – High level Network Management model based on the Femto NAM Security S.S0132-0, Femto Security Framework, projected completion 3Q09 S.S Some of the topics targeted for initial release: – Certificate-based Femto Access Point (FAP) authentication – Basic profiles for IKEv2, IPSec, and certificates – cdma2000 specific security enhancements, e.g. for SIP/IMS based 1x femtos

4 Requirements S.R System Requirements for Femto Cell Systems, published May 2008 S.R Phased development envisioned System Requirements Summary – General, e.g. supplementary services, location (FAP and mobile) – Radio, e.g. co-existence with macro, continuity of phases – Mobility, e.g. hand-out, hand-in – Security, e.g. authentication, admission control – OAM&P, e.g. self-configuration, parameter optimization wrt. macro – Other: Regulatory, Performance, Accounting

5 Next Steps SC.P5003-0, 3GPP2 Vision for 2009 and Beyond (projected completion 2Q09) contains “Femto Cell Support” in Section 8.2 SC.P – Phase 1 (current effort): Basic femto cell functionality Residential use, support of legacy mobiles, limited femto-macro mobility Closed access to a limited number of authorized subscribers for a femto – Phase 2 (future effort): Enhanced femto cell systems Comprehensive mobility: femto-femto HO, between dissimilar radio IF, etc. Enhancements to facilitate denser femto cell deployments Comprehensive Fixed Mobile Convergence – FAPs as home multi-media hubs – Potential benefits to operators Fuller integration into the macro network Support of load balancing and network controlled capacity management Improved interference mitigation Requirements Document may need to be revised to S.R0126-A – More detailed elaboration of Phase 2, after specs for Phase 1 complete Femto Cell System Overview (SC.R2006-1NN-0?), in planning stages – Document cross-TSG spec structure and feature support at sub-WI granularity
