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)

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
