cdma2000© FemtoStandardization Activities

in 3GPP2

17 February 20093

Background

• 3GPP2 began work on femtocell-related standardization in early 2007

• 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)

• Throughout 2008, extensive work has been done in all areas

• Publication expected in Q3-Q4 2009

17 February 20094

Drivers for Femtocell Work in 3GPP2

• Extremely high level of interest in femtocell technologies from cdma2000© system operators

• Femtocells for 1xRTT 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

17 February 20095

3GPP2 Standards Architecture – Key Aspects (1)

• Reflects SIP/IMS approach for 1x circuit services Voice services

Supplementary services (SMS, etc.)

Emergency and location services

• Packet data service model Reuse existing interfaces (A10/A11) to PDSN from FAPs

“Flat” model with packet data service terminated in FAPs is in roadmap for second release of specifications

• Security architecture using IPsec/IKEv2 Certificates with simple authentication model

Basic IPsec/IKEv2 profiles

17 February 20096

3GPP2 Standards Architecture – Key Aspects (2)

• Enhanced System Selection (ESS)/Preferred User Zone List (PUZL) Analogous to CSGs in 3GPP, with some additional functionality 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

• Air interface enhancements for 1x and EV-DO Enhancements for femto <-> macro system handoff Improved operation of ESS, etc.

• Local IP Access (Local Breakout) Access to owner’s local home network Direct access to the internet for Packet Data Service traffic Access to home network resources when mobile device is operating on the

macro system

3GPP2 Femtocell-Related Specifications

• System Requirements for Femto Cell Systems – S.R0126-0 v1.0 (published)

• Interoperability Specification (IOS) pieces – A.S0024 Includes Local IP Access support and anything special for femtos, e.g., handin/out

• Packet Data Service pieces – X.S0059 Multi-part (chapter) document includes packet data service aspects for 1x and DO,

as well as the SIP/IMS-based 1x legacy voice service Basic management object contents from 3GPP2 are being documented here as well

• Network Reference Model, etc., – S.S0135

• Security Framework – S.S0132

• Air Interface Enhancements for 1x and EV-DO (for future femto-aware mobile devices) Revision of EV-DO specification (C.S0024-C) 1x enhancement included in IS-2000 Rev. E Enhanced System Selection (ESS, a.k.a. PUZL) feature – C.S0016-D Analogous to the 3GPP Closed Subscriber Group (CSG) feature, but ESS is much

more sophisticated and flexible

17 February 200910

cdma2000 Femto Standards Activities Outside 3GPP2

• Definition of FAP management architecture TR-069-based approach Management objects defined formally by Broadband Forum (similar to

3GPP management architecture) cdma2000 1xRTT and EV-DO objects within Femto Forum management

object framework Re-use of major portions of management objects that are common (e.g.,

Security Gateway-related objects)• Shared experience of SIP/IMS femto architecture as 3GPP moves into

this area Eventual movement into Common IMS architecture 3GPP under

investigation Build on lessons learned in 3GPP2 SIP/IMS efforts

• Other areas of common interest with Femto Forum, 3GPP, etc. Local IP Access Regulatory issues
