  2. StandardsDevelopment Status • Stage-1 Requirements (S.R0087-0) published August 04. This document is under the responsibility of TSG S • Stage-2/3 Specification Phase I (X.P0028-0) completed (3Q04). Not published yet. This document is under the responsibility of TSG X Main features: • Common billing & Customer Care (scenario 1) • Common authentication (EAP-TLS; EAP-AKA) & WLAN Direct IP Access (scenario 2) • Stage-2/3 Specification Phase II (X.P0028-A). Completed (1Q06). Not published yet. This document is under the responsibility of TSG X Main features: • WLAN 3GPP2 IP Access (scenario 3) • Session Continuity (scenario 4)

  3. StandardsDevelopment Status • 3GPP2-00108 Support for Multi-mode System Selection. C.S0016-D v1.0, C.P0023-D v1.0, C.S0040-0 v1.0, C.P0064-A v1.0. These documents are under the responsibility of TSG C. Status open. • 3GPP2-00115 Support for Cross Notification on cdma2000 1x for Alternate Technologies C.P0075-0. In progress. This document is under the responsibility of TSG C.

  4. 3GPP2-WLAN IW Phase II Architecture • Support both scenario 3 and scenario 4 functionality. • Support packet data access using Simple IPv4 & IPv6, Mobile IPv4, and Mobile IPv6. • Support packet data access using a secure IP tunnel between MS and 3GPP2 system • Define a new logical network entity called Packet Data Interworking Function (PDIF) which among other things will serve as a tunnel termination point in 3GPP2 home or visited system. • Service authorization and mutual authentication between PDIF and MS shall be performed over the established secure tunnel between MS and 3GPP2 system. Basic EAP authentication is assumed to be successful prior to tunnel establishment. • Minimal impact to the existing PDSN interfaces or functionality (e.g., R-P interface) • Support roaming. • Support route optimization in IPv6.
