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.

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].
