Abstract

   This document authorizes IANA to allocate a block of Diameter command
   codes for the Third Generation Partnership Project 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.

           Provisional Diameter Command Codes for 3GPP Release 5



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 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 RFC-2119 [2119].

1.2 Abbreviations

   3GPP  Third Generation Partnership Project

   IMS   Internet Multimedia Subsystem


2. Command Code Allocation

   This document authorizes IANA to allocate 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 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 Consideration

   This document does not impact the security of the Internet.
