Home Networking
Use of cdma2000® Femto Cells
for Home Network
Applications
Geneva, 13-16 July 2009
Fostering worldwide interoperability
Background
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 Q1 2010

Background (2)
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

3
Drivers for the Work
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

Key Architecture 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
Air interface enhancements for 1x and EV-DO
Enhancements for improved femto <-> macro system handoff
Improved operation of Enhanced System Selection (ESS)
Geneva, 13-16 July 2009
Fostering worldwide interoperability
5
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 owner’s 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 user’s home
Femtocell (e.g., remote access)
Femto zone services

Strategic Direction
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
Geneva, 13-16 July 2009
Fostering worldwide interoperability
7
Challenges
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

8
Next Steps/Actions
Second phase will add requirements
for
Femto zone enhanced service capabilities
Interworking with other technologies (e.g., EUTRAN)
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
TIA proposes a revision to
Resolution GSC 13/12 Home
Networking to recognize the
Applicability of Femtocells for
Home Networks.
TIA Contribution GSC14-GTSC7008 Contains the proposed
revisions to the Resolution on
Home Networking.
