Femto System Architectureoverview only
• 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
• Single IPSec tunnel between Femto Cell and Gateway
