Network Working Group M. Wasserman, Ed. Request for Comments: 3314 Wind River Category: Informational September 2002 Recommendations for IPv6 in Third Generation Partnership Project (3GPP) Standards 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 (2002). All Rights Reserved. Abstract This document contains recommendations from the Internet Engineering Task Force (IETF) IPv6 Working Group to the Third Generation Partnership Project (3GPP) community regarding the use of IPv6 in the 3GPP standards. Specifically, this document recommends that the 3GPP specify that multiple prefixes may be assigned to each primary PDP context, require that a given prefix must not be assigned to more than one primary PDP context, and allow 3GPP nodes to use multiple identifiers within those prefixes, including randomly generated identifiers. The IPv6 Working Group supports the use of IPv6 within 3GPP and offers these recommendations in a spirit of open cooperation between the IPv6 Working Group and the 3GPP community. Since the original publication of this document as an Internet-Draft, the 3GPP has adopted the primary recommendations of this document. Conventions Used In This Document The key words "MUST", "MUST NOT", "REQUIRED", "SHALL", "SHALL NOT", "SHOULD", "SHOULD NOT", "RECOMMENDED", "MAY", and "OPTIONAL" in this document are to be interpreted as described in BCP 14, RFC 2119 [KEYWORD].

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.
