3GPP2 Primary Specifications 3GPP2 is focused on the development cdma2000®1 technologies. Air Interfaces cdma2000 1x – Rev 0 through E HRPD – Rev 0 through C Core Networks TIA-41 cdma2000 Wireless IP Network Open Service Access - Application Programming Interface Legacy MS Domain Multimedia Domain Multimedia Messaging Services Access Network Interfaces System Applications Vocoders 1cdma2000® is the trademark for the technical nomenclature for certain specifications and standards of the Organizational Partners (OPs) of 3GPP2. When applied to goods and services, the cdma2000® mark certifies their compliance with cdma2000® standards. Geographically (and as of the date of publication), cdma2000® is a registered trademark of the Telecommunications Industry Association (TIA-USA) in the United States.

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) Initial (Phase I) femtocell specifications completed Q1 2010 Revised (Phase II) specs support femtocells connecting to MSC/MSCe, to be completed Q3 2011

Key Features Preferred User Zone List (PUZL) as part of Enhanced System Selection (ESS) “Fingerprint” of the FAP (femtocell access point) location by the MS to assist in autonomous scanning and selection of FAPs, including handoff assistance Facilitate automatic FAP 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 or out-of-band detection Enhanced terminals supported through the new overhead message that advertises unique FAP identity Air interface enhancements for 1x and EV-DO Operates with unmodified macrocell systems (1x and EV-DO) Allows flexible partitioning of PN code space between macrocell system and femtocell system Augmented overhead for quick discovery of unique FAP identity, access type (open/restricted), human-friendly ID, location information
