3. Femto for Home Coverage  Cost effective to improve coverage and capacity at home No special terminal needed to provided CDMA services at home IP transmission over existing DSL line Plug-and-play for end user to install CDMA Femto at home Installed at home AT/MS CDMA Femto CDMA Core Network Internet /Intranet AGW DSL access

4. Femto Requirements Performance requirements The same voice quality as CS voice call The similar call setup time compared to macro network The same level of handoff success rate compared to macro network Ongoing femto service should have minimum impact on broadband connection such as xDSL Management and maintenances requirements Update of existing CN network should be minimum Ease to manage/configure/upgrade femto

5. Overview of femto A interface based femto solution Femto contains BTS+BSC+PCF functionality AGW provides aggregation function and PDSN function AGW connects to MSC/MSCe over A interface over IP IMS based femto solution Femto contains BTS+BSC+PCF+PDSN functionality Femto support SIP client for 1x terminal AGW provides aggregation function AGW connects to internet or 3GPP2 CN over IP

8. A Interface Based Femto BTS+BSC+PCF solution ›Femto contains BTS+BSC+PCF function ›AGW aggregates the signaling+data flow ›Support 1x/DOtechnology ›AGW acts as PDSN function also ›AGW connects to MSC for supporting 1x voice call

9. A Interface Based Architecture Entities Femto ›BTS+BSC+PCF function (including 1x and HRPD) ›Tunnel management for signaling and data  Fat pipeline between the femto and the AGW  Per user per tunnel ›Self-configuration AGW ›A1/A2/A5 interface support over IP or E1/T1 for CS domain ›Relay A1/A2/A5 interface message to the MSC ›PDSN function ›P-P interface support for fast handoff ›Tunnel management for signaling and data ›Femto’s Authenticator ›ESN/MEID/IMSI based access control for 1X ›NAI based access control for DO FHR ›AAA Server provides Diameter/Radius interface for Femto

10. Femto Authentication and Registration Mutual authentication is preferred, the network must authenticate the device ›AGW behaves as authenticator, FHR acts as authentication server IKEv2 is used for femto authentication ›refer to X.S0028-200 When authentication successes, the Femto’s profile is downloaded from the AAA IPSec tunnel is setup for conveying signaling of cdma system FemtoAGWFHR IKEv2 AuthenticationDiameter/Radius IPSec Tunnel
