Femto System Architecture overview 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
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
