Diameter Command Codes for Third Generation Partnership Project (3GPP) Release 5

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.
