Diameter Parameter Allocation
IANA allocates Diameter or AAA parameters, according to
RFC 3588, and
these allocations are detailed at:
In particular, IANA allocates all Diameter Application ID’s and
Command Codes. IANA also allocate all ‘IETF consensus’ AVP codes and
AVP specific values. Entities other than IANA can issue ‘vendor
specific’ AVP codes and AVP specific values, and Experimental Result
Codes, using IANA-allocated ‘enterprise numbers’.
ETSI’s enterprise number is 13019.
3GPP’s enterprise number is 10415.
ETSI CTI manages the allocation of ETSI AVP codes, AVP specific
values and Experimental Result Codes.
ETSI CTI also handles
requests to IANA for Diameter Application ID’s.
To request a code allocation, please send an email to
Please provide name, e-mail address, and details of the ETSI TB for
which the registration is required.
Please provide details of the type of registration requested, and
(draft) ETSI specification for which the registration is required.
ETSI generally allocates a block of 50 AVP codes to each specification in which
Diameter AVP codes are specified, and a block of 20 Experimental Result Codes to
each specification in which these codes are specified. Allocation
is performed on a first-come, first-served basis.
If new Command Codes, or IETF consensus AVP codes or values are
required, specification activity needs to be performed at the IETF.
ETSI Diameter parameters
No AVP specific values which require global management have yet been
assigned by ETSI.
3GPP Diameter parameters
Diameter parameters used in 3GPP specifications are detailed in
3GPP TS 29.230
