               3GPP2 Standards Architecture
                      – Key Aspects
• 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
• 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

                          Femtocell Device Management

• TSG-X PDS proposed using TR-069 for femto cell auto-configuration
  – Each TSGs (TSG-X, TSG-A and TSG-C) will specify auto-configuration parameters within their
    scopes
  – X.P0059-300 plans to contain at least network related auto-configuration parameters
       • Whether other TSGs auto-configuration parameters will be contained in this document are TBD
• TR-069 family of standards defined by Broadband Forum to manage “touch-free”
  CPE devices in a very general manner
  –   Discovery
  –   Configuration
  –   Alarming/Event reporting
  –   Etc.
• Some access technologies agonistic auto configuration parameters may be reused
  by 3GPP2
  – What 3GPP/FF/BBF-defined HNB/HeNB auto-configuration parameters can be reused are for
    further studies
  – Examples: IPsec, timing, GPS/location, etc.
• 3GPP2 specific auto configuration parameters are FFS
• Liaison Relationship with Broadband Forum is under investigation

                                                                                                       7

                         or Liaison Activities
•   Definition of FAP management architecture
     – TR-069-based approach
     – Expected that management objects will be converted into TR-069 objects
        by the Broadband Forum (similar to 3GPP management architecture)
     – cdma2000 1x 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)
•   Consider working with 3GPP on SIP/IMS femto architecture
     – Ensure 1x-specific services are supported by 3GPP2 standards
•   Other areas of common interest with Femto Forum and 3GPP
     – Local IP Access
     – Regulatory issues
•   TSG-X proposed to manage external liaison relationships for these
    femtocell activities (with inputs from all TSGs as appropriate)
