v6ops-3GPP Design Team
V6ops Interim meeting
Sunnyvale, USAJonne Soininen
18.9.2002
2 18.9.2002 / Jonne Soininen
Scope & Goal
• Identify relevant transition scenarios• Map relevant transition mechanisms to the scenarios
• Identify relevant transition mechanisms• Perform “Gap Analysis” – I.e. identify missing
transition tools• Make recommendations for usage of transition tools• Document the results
• Scenarios• Solutions• Gaps• Recommendations
• Discuss these in the WG• A Non-Goals
• Specify new transition mechanisms• Change 3GPP specs

People & Deliverables
• Design team members• Margaret Wasserman (v6ops Chair)• Alain Durand• Jonne Soininen• Juha Wiljakka• Hesham Soliman• Karim El-Malki• Hugh Shieh• Niall Murphy• Paul Francis
• Deliverables• Scenarios Document
• draft-soininen-v6ops-3gpp-cases-00.txt (old draft-soininen-ngtrans-3gpp-cases-00.txt)
• draft-wiljakka-3gpp-ipv6-transition-01.txt

Changes to Scenarios Document
• Introduction to relevant 3GPP concepts added• GPRS basics• IMS basics
• PDP Type PPP added
• “Pictures” Added• Hopefully to clarify
• This document should be pretty stable by now
