Abstract

   This document describes different scenarios in Third Generation
   Partnership Project (3GPP) defined packet network, i.e., General
   Packet Radio Service (GPRS) that would need IP version 6 and IP
   version 4 transition.  The focus of this document is on the scenarios
   where the User Equipment (UE) connects to nodes in other networks,
   e.g., in the Internet.  GPRS network internal transition scenarios,
   i.e., between different GPRS elements in the network, are out of
   scope.   The purpose of the document is to list the scenarios for
   further discussion and study.
