1. Introduction

   In May 2001, the IPv6 Working Group (WG) held an interim meeting in
   Redmond, WA to discuss the use of IPv6 within the 3GPP standards.
   The first day of the meeting was a joint discussion with 3GPP, during
   which an architectural overview of 3GPP's usage of IPv6 was
   presented, and there was much discussion regarding particular aspects
   of IPv6 usage within 3GPP.  At that meeting, a decision was made to
   form a design team to write a document offering advice from the IPv6
   WG to the 3GPP community, regarding their use of IPv6.  This document
   is the result of that effort.

   This document offers recommendations to the 3GPP community from the
   IETF IPv6 Working Group.  It is organized into three main sections:

      1. An introduction (this section) that provides background
         information regarding the IETF IPv6 WG and the 3GPP and
         includes a high-level overview of the technologies discussed in
         this document.
