1 Femto Cell System Overview S.P Status Update to CDG and Femto Forum Fukuoka, Japan, September 2010

2 Introduction 3GPP2 TSG-S is developing Femto Cell System Overview –Technical Report S.R0139 under development in WG1 –Femto Phase I specs complete; experts can focus on S.P0139 –First part (Section 4) is femto specification inventory, similar to System Release Guide –More in-depth contents (Section 5) can be co-published with CDG, Femto Forum, or both (an open question) Main purpose of the document: –Provide guidance to operators and others on femto cell deployment issues –Pull together in one place relevant information regarding femto cell specifications, with minimum restatement of specs –Describe not just what is specified in standards, but what is feasible with cdma2000 femto cells –A vehicle to promote 3GPP2 femto cells to broader community

3 Status Outline Started contributing in December ’09 – some topics: –Deployment phases »Legacy and femto-aware mobile support »Macro network evolution steps, etc. –Spectrum allocation scenarios – dedicated and reuse –Macro system configuration, e.g.: »Neighbor lists »Macro and femto pilot phase planning »Transition issues from legacy to femto-aware mobile support Femto Forum expressed desire to participate/review CDG is encouraged to do likewise Progressed the development slowly while awaiting completion of Technical Specifications in TSGs It is now time to accelerate completion & initial publication Latest Draft: S.P v0.5 attached

9 Way Forward Contents is open for additional input –Now or in subsequent version updates (sooner is better) –CDG has been briefed during Sept meeting in Fukuoka –Femto Forum is likewise informed of status via correspondence –Both are kindly asked to evaluate contents, comment on general direction –Goal is to retain market focus and real deployment needs/wants Schedule Outline (target assuming 3GPP2 publication proc.) –Additional input received in Sept. ‘10 meeting, and expected in Oct. ‘10 meeting –October ‘10: Complete draft text and start TSG Review »Minor additional input may be allowed, otherwise future version update –January ‘11: Complete TSG Review, start V&V –March ‘11: Complete V&V and Publish After Phase I version is published, start work on Rev. A for Phase II features, as well as filling any gaps in Rev. 0

10 Open Discussion Development and Publication –3GPP2 expertise is essential in document development, but deployment and recommended practices are typically outside the scope of 3GPP2 –Femto Forum expressed keen interest in assisting (April 2009) and possibly jointly publishing –CDG is likewise interested in publication plans, contents –3GPP2 should retain overall control Carious publication options still on the table –Leave with 3GPP2 –Femto Forum –CDG –Any combination of above Document changes/additions based on publication plan –Need to further discuss division of labor for joint or collaborated 3GPP2/CDG/Femto Forum publication(s)
