TIA WLAN Inter-working Standards

• Phase I standards support public WLAN hot spot
  roaming of cdma2000 subscribers for Access
  Control and Charging . Phase I standards are
  complete awaiting publication.
• Phase IIa standards support access to cdma2000
  operator data and IMS services. Phase IIa
  standards are in balloting for publication.
• Phase IIb work supports IMS/VoIP handoffs between
  WLAN access and cdma2000 packet access networks.
  Phase IIb is in stage 2 and stage 3 discussions.
• TIA WLAN Standards are developed in conjunction
  with 3GPP2

Voice Call Continuity

• Voice Call Continuity (VCC) project supports
  voice handoffs between IMS VoIP and circuit-based
  networks. VCC is in stage 2 and stage 3
  discussions
• Types of VCC handoffs supported
• IMS WLAN VoIP to Circuit Voice
• IMS cdma2000 VoIP to Circuit Voice
• Circuit Voice to IMS WLAN VoIP
• Voice Call Continuity (VCC) Issues
• Call management issues between IMS and circuit
  network
• Supplementary services support between IMS and
  circuit network
• Alignment with 3GPP VCC work
