Network Working Group J. Soininen, Ed. Request for Comments: 3574 Nokia Category: Informational August 2003 Transition Scenarios for 3GPP Networks Status of this Memo This memo provides information for the Internet community. It does not specify an Internet standard of any kind. Distribution of this memo is unlimited. Copyright Notice Copyright (C) The Internet Society (2003). All Rights Reserved. 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. Table of Contents 1. Introduction . . . . . . . . . . . . . . . . . . . . . . . . . 2 2.

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). Soininen Informational [Page 2] RFC 3574 Transition Scenarios for 3GPP Networks August 2003 3.1. GPRS Architecture Basics This section gives an overview to the most important concepts of the 3GPP packet architecture. For more detailed description, please see [1]. From the point of view of this document, the most relevant 3GPP architectural elements are the User Equipment (UE), and the Gateway GPRS Support Node (GGSN). A simplified picture of the architecture is shown in Figure 1. The UE is the mobile phone. It can either be an integrated deviceShow full document text
