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.

RFC 3574 Transition Scenarios for 3GPP Networks August 2003
1. Introduction
This document describes the transition scenarios in 3GPP packet data
networks that might come up in the deployment phase of IPv6. The
main purpose of this document is to identify and to document those
scenarios for further discussion and study them in the v6ops working
group.
Just a brief overview of the 3GPP packet data network, GPRS, is given
to help the reader to better understand the transition scenarios. A
better overview of the 3GPP specified GPRS can be found for example
from [6]. The GPRS architecture is defined in [1].
2. Scope of the Document
The scope is to describe the possible transition scenarios in the
3GPP defined GPRS network where a UE connects to, or is contacted
from, the Internet or another UE. The document describes scenarios
with and without the usage of the SIP-based (Session Initiation
Protocol [5]) IP Multimedia Core Network Subsystem (IMS). The 3GPP
releases 1999, 4, and 5 are considered as the basis.
Out of scope are scenarios inside the GPRS network, i.e., on the
different interfaces of the GPRS network. This document neither
changes 3GPP specifications, nor proposes changes to the current
specifications.
In addition, the possible transition scenarios are described. The
solutions will be documented in a separate document.
All the possible scenarios are listed here. Further analysis may
show that some of the scenarios are not actually relevant in this
context.
3. Brief Description of the 3GPP Network Environment
This section describes the most important concepts of the 3GPP
environment for understanding the transition scenarios. The first
part of the description gives a brief overview to the GPRS network as
such. The second part concentrates on the IP Multimedia Core Network
Subsystem (IMS).
