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.

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.

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

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].
