Abstract

   This document analyzes the transition to IPv6 in Third Generation
   Partnership Project (3GPP) packet networks.  These networks are based
   on General Packet Radio Service (GPRS) technology, and the radio
   network architecture is based on Global System for Mobile
   Communications (GSM) or Universal Mobile Telecommunications System
   (UMTS)/Wideband Code Division Multiple Access (WCDMA) technology.

   The focus is on analyzing different transition scenarios and
   applicable transition mechanisms and finding solutions for those
   transition scenarios.  In these scenarios, the User Equipment (UE)
   connects to other nodes, e.g., in the Internet, and IPv6/IPv4
   transition mechanisms are needed.

1.  Introduction

   This document describes and analyzes the process of transition to
   IPv6 in Third Generation Partnership Project (3GPP) General Packet
   Radio Service (GPRS) packet networks [3GPP-23.060], in which the
   radio network architecture is based on Global System for Mobile
   Communications (GSM) or Universal Mobile Telecommunications System
   (UMTS)/Wideband Code Division Multiple Access (WCDMA) technology.

   This document analyzes the transition scenarios that may come up in
   the deployment phase of IPv6 in 3GPP packet data networks.

   The 3GPP network architecture is described in [RFC3314], and relevant
   transition scenarios are documented in [RFC3574].  The reader of this
   specification should be familiar with the material presented in these
   documents.

   The scenarios analyzed in this document are divided into two
   categories: general-purpose packet service scenarios, referred to as
   GPRS scenarios in this document, and IP Multimedia Subsystem (IMS)
   scenarios, which include Session Initiation Protocol (SIP)
   considerations.  For more information about IMS, see [3GPP-23.228],
   [3GPP-24.228], and [3GPP-24.229].
