Abstract

 This document describes the IANA's allocation of a block of Diameter
 Command Codes for the Third Generation Partnership Project (3GPP)
 Release 5.  This document does not pass judgment on the usage of
 these command codes.  Further more, these command codes are for use
 for Release 5.  For future releases, these codes cannot be reused,
 but must be allocated according to the Diameter Base specification.

Loughney Informational [Page 1] RFC 3589 Diameter Command Codes for 3GPP Release 5 September 2003

1. Introduction

 The Third Generation Partnership Project (3GPP) is defining the
 Internet Multimedia Subsystem (IMS) as part of their Release 5
 architecture.  As part of this architecture, they have defined a
 Diameter application [29.229] and [29.329] which requires the use of
 new Diameter Command Codes [DIAM].

1.1. Abbreviations

 3GPP  Third Generation Partnership Project
 IANA  Internet Assigned Name Authority
 IMS   Internet Multimedia Subsystem

2. Command Code Allocation

 The IANA has allocated Diameter Command Codes 300 through 313, for
 use in 3GPP Release 5.  The protocols defined by these command codes
 have not been carefully reviewed by the IETF community and are not
 considered to be general mechanisms appropriate for broad usage.
 More work is needed to develop general mechanisms and may become a
 work item of an IETF Working Group.  These command codes are intended
 to be used for 3GPP Release 5 only [29.228], [29.229].  Future 3GPP
 releases are expected to make use of alternate mechanisms.
 Command codes for 3GPP Release 6 are expected to be allocated from
 the standard command space, with IETF documentation.  The current
 intent as agreed with 3GPP is to develop a standards track
 application addressing the needs of AAA for SIP/SDP and encompassing
 the requirements of the cellular community.

3. Security Considerations

 This document is not known to affect the security of the Internet.

4. Intellectual Property Statement

 The IETF takes no position regarding the validity or scope of any
 intellectual property or other rights that might be claimed to
 pertain to the implementation or use of the technology described in
 this document or the extent to which any license under such rights
 might or might not be available; neither does it represent that it
 has made any effort to identify any such rights.  Information on the
 IETF's procedures with respect to rights in standards-track and
 standards-related documentation can be found in BCP-11.  Copies of
 claims of rights made available for publication and any assurances of
 licenses to be made available, or the result of an attempt made to
 obtain a general license or permission for the use of such
 proprietary rights by implementors or users of this specification can
 be obtained from the IETF Secretariat.
 The IETF invites any interested party to bring to its attention any
 copyrights, patents or patent applications, or other proprietary
 rights, which may cover technology that may be required to practice
 this standard.  Please address the information to the IETF Executive
 Director [2026].
