AGENDA ITEM 4.3
CONTACT(S) Cheryl Blum/Dan Bart
Home Networking

• Use of cdma2000 Femto Cells for Home Network
  Applications

2
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

3
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

4
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

5
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 lt-gt macro system
  handoff
• Improved operation of Enhanced System Selection
  (ESS)

6
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

7
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

8
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

9
Next Steps/Actions

• 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.

10
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-GTSC7-008 Contains the
  proposed revisions to the Resolution on Home
  Networking.
