Fostering worldwide interoperabilityGeneva, July 2009 Use of cdma2000 ® Femto Cells for Home Network Applications Home Networking Global Standards Collaboration (GSC) 14 DOCUMENT #:GSC14-GTSC7-007R1 FOR:Presentation SOURCE:TIA AGENDA ITEM:4.3 CONTACT(S):Cheryl Blum/Dan Bart

Fostering worldwide interoperability 2 Geneva, July 2009 TIA members working closely through their partnership in 3GPP2 to develop specifications to support cdma2000 ® -based Femto cells 3GPP2 began work on Femtocell-related standardization in early 2007 Femtocell Workshop was held in October 2007 in Boston Extensive work has been done in all areas System requirements Security aspects Air interface (radio) enhancements Support for legacy 1x circuit services Packet data services for 1x and HRPD (EV-DO) Publication expected by Q Background

Fostering worldwide interoperability 3 Geneva, July 2009 Femto Cells may be deployed in various applications As a Home Network thus of interest to GTSC In an Enterprise Application Or a Service Provider may use as an adjunct in its serving areas Background (2)

Fostering worldwide interoperability 4 Geneva, July 2009 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 Partner (MRP) relationship with 3GPP2 Drivers for the Work

Fostering worldwide interoperability 5 Geneva, July 2009 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 Air interface enhancements for 1x and EV-DO Enhancements for improved femto macro system handoff Improved operation of Enhanced System Selection (ESS) Key Architecture Aspects (1)

Fostering worldwide interoperability 6 Geneva, July 2009 Key Architecture 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 Local IP Access (Local Breakout) Access to owners local Home Network Packet Data Service traffic can flow directly to Home Internet service Access to Home Network resources when mobile device is operating on the macro system via the users home Femtocell (e.g., remote access) Femto zone services

Fostering worldwide interoperability 7 Geneva, July 2009 Develop Femto cell standards to support Increased coverage Home Network enhanced services Relationship with Broadband Forum is being established for publication of Femto Data Object models Coordination with Femto Forum to address industry considerations Strategic Direction

Fostering worldwide interoperability 8 Geneva, July 2009 Coordination with Broadband Forum on publication schedules Potential coordination with 3GPP for interoperability Ensuring 1x features are fully supported on a SIP/IMS Femto architecture Regulatory Issues for Femto cells including the Home Network Applications Local IP Access Emergency Services Lawfully Authorized Electronic Surveillance Challenges

Fostering worldwide interoperability 9 Geneva, July 2009 Second phase will add requirements for Femto zone enhanced service capabilities Interworking with other technologies (e.g., E- UTRAN) Lawfully Authorized Electronic Surveillance Femto support for Enterprise Systems Continue close collaborative work with Femto Forum and Broadband Forum and others working in this area. Next Steps/Actions

Fostering worldwide interoperability 10 Geneva, July 2009 TIA proposes a revision to Resolution GSC 13/12 Home Networking to recognize the Applicability of Femtocells for Home Networks. TIA Contribution GSC14-GTSC Contains the proposed revisions to the Resolution on Home Networking. Next Steps/Actions
