cdma2000 Femto Standardization Activities in 3GPP2 Presenter: Douglas Knisely Airvana, Inc. Femtocell World Congress June 2009 Heathrow, UK

1 Background 3GPP2 began work on femtocell-related standardization in early 2007 TSG-S sponsored 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 Publication expected by Q1 2010

2 Drivers for Femtocell Work in 3GPP2 Extremely high level of interest in femtocell technologies from cdma2000 ® system operators Femtocells for 1x services already deployed by two major system operators Evolution to SIP/IMS-based architecture considered essential Femto Forum has a strong Market Representation Partnership (MRP) relationship with 3GPP2 Maximum re-use of existing 3GPP2 interfaces and entities cdma2000® is the trademark for the technical nomenclature for certain specifications and standards of the Organizational Partners (OPs) of 3GPP2. Geographically (and as of the date of publication), cdma2000® is a registered trademark of the Telecommunications Industry Association (TIA-USA) in the United States.

3 3GPP2 Standards Architecture – Key Aspects (1) Reflects 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 FAPs –Packet data service terminated in FAP is in roadmap for second release of specifications Security architecture using IPsec/IKEv2 –Certificates with simple authentication model –Basic IPsec/IKEv2 profiles

4 3GPP2 Standards Architecture – Key Aspects (2) Enhanced System Selection (ESS)/Preferred User Zone List (PUZL) –Provisioned data structures that supplement the existing Preferred Roaming List (PRL) –Operates with unmodified macro systems (1x and EV-DO) –Addresses the notion of “autonomous” learning of PUZL information by mobile devices –Analogous to CSGs in 3GPP with some additional functionality Air interface enhancements for 1x and EV-DO –Enhancements for improved femto macro system handoff –Improved operation of ESS

5 3GPP2 Standards Architecture – Key Aspects (3) Local IP Access (Local Break-out) –Access to owner’s home network –Packet Data Service traffic can flow directly to home Internet service Remote IP Access (Local Break-in) –Access to owner’s home network via the home femtocell when mobile device is operating on the macro system TR-069-based management architecture –Specification of Management Object contents and procedures (e.g., discovery, registration, provisioning) –New specification produced by the 3GPP2 Femto MO Ad Hoc Group –Formal definition of MOs to be included into Broadband Forum specification TR-196 via liaison relationship

6 3GPP2 Reference Architecture – 1x Circuit

7 3GPP2 Reference Architecture – Packet Data (Legacy)

8 3GPP2 Reference Architecture – Packet Data (Release 2)

9 3GPP2 Femtocell-Related Specifications System Requirements for Femto Cell Systems – S.R v1.0 Interoperability Specification (IOS) pieces – A.P0024 –Includes Local IP Access support, handin/out, etc. Packet Data Service pieces – X.P0059 –Packet data service aspects for 1x and EV-DO –SIP/IMS-based 1x legacy voice service –Basic management object contents Femto Management Objects – NEW Network Reference Model, etc., – S.R0135 OAM&P for cdma2000 – S.S0028-E Security Framework – S.S0132 Air Interface Enhancements for future femto-aware mobile devices –EV-DO – C.P0024-C –1x enhancement – C.P0005-E –Enhanced System Selection (ESS, a.k.a. PUZL) – C.P0016-D Enhanced version of the 3GPP Closed Subscriber Group (CSG) feature –Signaling conformance tests Performance requirements for FAPs

10 3GPP2 Organization Structure and Roles in Femtocell-Related Work 3GPP2 Organizational Partners/ Steering Committee TSG-A Access Network Interfaces TSG-C Radio Access TSG-S Service and System Aspects TSG-X Core Networks Local IP Access Device Authentication RAN Management Objects Interworking between femto and macro systems Enhanced System Selection 1x and EV-DO Radio Interface Enhancements Minimum Performance Specifications Air Interface Management Objects System Requirements Security Architecture 3GPP2 Program Management 3GPP2 Vision Network Reference Model System Management Model Femto MO Ad Hoc Group Packet Data Service Aspects Security Protocols Reference architecture for femtos SIP/IMS-based Circuit Service Architecture and Protocols IP-related Management Objects Femto Forum MRP Relationship

11 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 are managed only by ACS –AAA and back-office interfaces are required only on ACS

14 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
