  5. 3GPP2 Organizational Structure

  6. Current 3GPP2 IP Activities(2/2) • TSG-A • Developing specifications for IP based transport from the BTS to the BSC (Abis) • Doing a study on access network re-design to support an IP based access network • Currently interfaces A8 - A11 are mobile IP v4 based • TSG-P • cdma2000 packet data specification is based on mobile IP v4. • Working to incorporate IP v6 support • Expanding the specification to help support multimedia (SIP) call model • TSG-N • Developing specifications to support existing mobiles over an IP based core network • Starting to develop specification, in conjunction with TSG-P to support multimedia (SIP) mobiles on an IP based core network

  7. What is “All IP” in 3GPP2 • “All IP” is the concept of moving the current wireless network architecture from the current circuit based concept to a packet based architecture utilizing IP protocols and technology where possible.

  8. 3GPP2 All IP History • Ad Hoc formed to perform initial study - November 1999. • Ad Hoc results submitted to the 3GPP2 Steering Committee (SC) at the November 2000 SC meeting in Tokyo. • Original Ad Hoc was formally dissolved at the SC meeting. • New Ad Hoc was formed under TSG-S in December, 2000. • Mark Lipford (Sprint PCS) was appointed Chair. • Operates with some level of autonomy as instructed by the 3GPP2 SC, and reports regularly to TSG-S. • Responsible for Requirements, Architecture, Project Management. • Meetings are monthly.

  9. Current 3GPP2 IP Activities (1/2) • TSG-S All IP AdHoc • Continuing to refine the architecture • Adding clarification to the requirements • Identifying release content • Project managing the overall project • Coordinating work across Technical Specification Groups (TSGs)

  10. All IP Architecture (Based on IP v4)

  11. Current 3GPP2 IP v6 Activities • TSG-P is currently working to include support for IP v6 into the next release of P.S0002. Scheduled to be published 4Q01. • All IP AdHoc is working to define how IP v6 should be supported in the first release of All IP specifications. • Hosted two meetings to discuss issues, concerns, and requirements relating to IP v6

  12. All IP Architectural Principal • Current Architectural Principal is: • “The All-IP architecture shall be designed in such a way that a migration from IPv4 to IPv6 is feasible and that IPv4 and IPv6 based All-IP networks may interoperate”

  13. IP v6 Requirements on All IP • Operators realize the need for IP v6 addressing due to limited v4 address availability • Need to allow for existing IP v4 users on All IP network • Need to allow both IP v4 and IP v6 users access to applications and services on IP v4 networks (possibly v6 networks)

  14. IP v6 Impacts • Operators need to support IP v4 and v6 users on same network • Possible Changes in architecture

  15. 3GPP2 Concerns with IP v6 • Recent issues from the March IETF meeting relating to security holes in binding update • Is mobile IP v6 baked enough to base voice grade services on it • How will v6 networks interact with services on v4 networks.
