2. 2 Femto System Architecture Why Do This? Femto Forum has applied to be a 3GPP2 MRP Femto Forum can develop “common” architectural reference –Map 3GPP2 system onto Forum Architecture –Determine required extensions to support cdma2000 Minimize potential divergence of architectures inside and outside 3GPP2 Encourage Femto Forum adoption of 3GPP2 architectural requirements

7. 7 Femto System Architecture Same Goals as Before Maximize Reuse –Use existing IOS signaling and functions in Femto Cell –Gateway acts as IOS Relay for A12, A13, A16, A21 protocols –Core network and other RAN elements unchanged Minimize Complexity of Femto Cell –Use existing IOS signaling and functions in Femto Cell –Localize required changes to Femto Gateway –Maximize economies of scale where feasible (e.g., IOS/SIP conversion) by locating new function(s) in Femto Gateway Ease deployment into existing network
