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.S 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. Operators need to support IP v4 and v6 users on same network
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.
