Background
• 3GPP2 began work on femtocell-related standardization in early 2007– Kicked off through a femtocell workshop in October 2007 in
Boston• Technical activities were initiated in all 3GPP2 TSGs in
late 2007– System requirements– Security aspects– Air-interface (radio) enhancements– Support for legacy 1x circuit services– Packet data services for 1x and HRPD (EV-DO)
• Extensive work has been done in all areas• Phase I femtocell specifications expected by Q1 2010

3GPP2 Standards : Architecture
• SIP/IMS approach for 1x circuit services– Voice services– Emergency and location services– SMS– Supplementary services
• Packet data service model– Reuse existing interfaces (A10/A11) to PDSN from Femto
Access Points (FAPs)• Security architecture using IPsec/IKEv2
– Certificates with simple authentication model– Basic IPsec/IKEv2 profiles
• TR-069-based management architecture– Specification of Management Object contents and procedures

3GPP2 Standards : Key Features
• Preferred User Zone List (PUZL) as part of Enhanced System Selection (ESS)
– “Fingerprint” of the FAPs location to assist autonomous scanning and selection of FAPs
– Facilicate manual selection, black list and white list management in terminals• Active handoff from macro to FAP
– Legacy terminals supported through the reverse-link detection of mobile signal
– Enhanced terminals supported through the new overhead message that advertises unique FAP identity
• Air interface enhancements for 1x and EV-DO– Operates with unmodified macro systems (1x and EV-DO)– Allows flexible partitioning of PN code space between macro system
and femto system– Augmented overhead for quick discovery of unique femto identity,
association type, human-friendly ID, location information

Role of The TR-069 Standard in Femtocell Management
• Broadband Forum TR-069 has been selected as the framework for femtocell management– Widely supported by 3GPP2 (and 3GPP) vendors and carriers– Endorsed by Femto Forum
• Management architecture and TR-069 ACS are the backbone of the key femtocell operational and provisioning call flows in 3GPP2 (and 3GPP)– Discovery/Registration– Redirection to alternate SeGW, ACS, or Femto Gateway– Self-organizing network– Location verification– Provisioning and radio parameter assignments

3GPP2 Femtocell-Related Specifications
• System Requirements for Femto Cell Systems – S.R0126-0 v1.0• Interoperability Specification (IOS) pieces – A.S0024
– Includes Local IP Access support, handin/out, etc.• Packet Data Service pieces – X.S0059
– Packet data service aspects for 1x and EV-DO– Remote IP Access support– SIP/IMS-based 1x legacy voice service
• Femto Management Objects – X.R0063• Network Reference Model, etc., – S.R0135• Security Framework – S.S0132• Air Interface Enhancements for future femto-aware mobile devices
– EV-DO – C.S0024-C– 1x enhancement – C.S0005-E published– Enhanced System Selection (ESS, a.k.a. PUZL) – C.P0016-D– Signaling conformance tests
• Performance requirements for FAPs

Complementary cdma2000 Femto Standards Activities Outside 3GPP2
• Close cooperation with Broadband Forum to ensure that 3GPP2-specified Management Objects get incorporated into TR-196
• Consider working with 3GPP on SIP/IMS femto architecture– Ensure 3GPP2 1x-specific services are supported
by 3GPP standards• Other areas of common interest with Femto Forum
and 3GPP2– Local IP Access– Regulatory issues
10
Future Enhancements of 3GPP2 femtocells
• Example of features that are being considered for Phase II of 3GPP2 femtocells– Femto flatter architecture (e.g., bringing some PDSN
function into femtocell)– Mobility enhancements– Inter-technology Interworking– IOS interfaces support– Backhaul optimization
