3. HUAWEI TECHNOLOGIES Co., Ltd. Page 3 cdma 1x FemtoCell Architecture-IOS based FAP –Contains BTS/BSC/PCF function –Provides A1p/A2p/A10/A11 interface to the FGW –Support IPSec FGW –Proxy of A1p/A2p/A10/A11 –Provide standard A1/A1p/A2/A2p Interface to the MSC –Provide standard A10/A11 interface to the PDSN –Support IPSec

4. HUAWEI TECHNOLOGIES Co., Ltd. Page 4 cdma 1x FemtoCell Architecture-IOS based No change to cdma1x Core Network –FGW acts as a A1p/A2p/PCF proxy, MSC/PDSN just see the FGW as a BSC/PCF Support both CS and PS service Limited mobility cases support –FemtoCell handoff to Macro handoff Low cost of FemtoCell Need deployed macro 1x system support

5. HUAWEI TECHNOLOGIES Co., Ltd. Page 5 cdma 1x FemtoCell Architecture-IMS based FGW –Proxy of A1p/A2p/A10/A11 –Support SIP client function in order to convert A1p signaling to SIP signaling –RTP transport of user traffic –Provide standard A10/A11 interface to the PDSN –Support IPSec FAP –Contains BTS/BSC/PCF function –Provides A1p/A2p/A10/A11 interface to the FGW –Support IPSec

6. HUAWEI TECHNOLOGIES Co., Ltd. Page 6 cdma 1x FemtoCell Architecture-IMS based IMS network support is needed Support both CS and PS service, but the delay of CS call setup is longer than traditional 1x CS call setup Limited mobility cases support –FemtoCell handoff to Macro handoff, and handoff performance is worse than the IOS based handoff Still need HLR for subscription management
