cdma2000 Femto Standardization Activities in 3GPP2 … Femtocell World Summit June 21 st -23 rd, 2011 London, UK

1 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) Phase I femtocell specifications completed by Q Phase II specs support femtocells connecting to MSC/MSCe, to be completed Q2 2011

2 3GPP2 Standards : Architecture Two possible architectures for voice –Legacy IOS interface connecting to existing MSC/MSCe –SIP/IMS approach for connecting femtocells to IMS convergence server 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

3 3GPP2 Femtocell System Architecture (IMS)

4 3GPP2 Femtocell System Architecture (Legacy IOS-based)

5 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 –Facilitate 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 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 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

6 3GPP2 standards: LIPA and RIPA Femto / Router handset in femto coverage PDSN Media Server Printer TV Home IP Domain Operator’s Backhaul handset in macro network Operator’s IP Domain Internet Residential Backhaul (Firewall) WWW

7 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 Functions controlled via provisioning –Discovery/Registration –Redirection to alternate SeGW, ACS, or Femto Gateway –Self-organizing network –Location verification –Provisioning and radio parameter assignments 3GPP2 FAP device management model is included as part of TR-196 issue 2 – to be published soon

8 3GPP2 Femtocell-Related Specifications System Requirements for Femto Cell Systems – S.R v1.0 Femtocell System Overview – S.R –Providing guideline to operators on deployment considerations for cdma2000 femtocells Interoperability Specification (IOS) – A.S0024 –Includes handin/out, IOS interface support for connecting to MSC/MSCe Packet Data Service pieces – X.S0059 –Packet data service aspects for 1x and EV-DO –Local and Remote IP Access support –SIP/IMS-based 1x legacy voice service Femto Management Objects – X.R0063 (subset of TR-196 issue 2) 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 –Enhanced System Selection (ESS, a.k.a. PUZL) – C.P0016-D –Signaling conformance tests Performance requirements for FAPs
