Abstract
This document describes the need for a new IANA Diameter Command Code
to be used in a vendor-specific new application for invocation of
Policy Processing (Policy Evaluation, or Evaluation and Enforcement).
This application is needed as one of the implementations of the Open
Mobile Alliance (OMA) Policy Evaluation, Enforcement and Management
(PEEM) enabler, namely for the PEM-1 interface used to send a
request/response for Policy Processing.

RFC 5224 PEEM March 2008
1. Introduction
This document summarizes the use of Diameter codes in a newly defined
realization of a specification for invocation of policy processing.
A new Command Code has been assigned by IANA. The document
summarizes the uses of newly defined Diameter codes (a Command Code,
an AVP, and a vendor-specific application id). When combined with
the Diameter Base protocol, this application's specification
satisfies the Open Mobile Alliance (OMA) Policy Evaluation,
Enforcement, and Management (PEEM) requirements for sending a request
for policy processing and receiving a response with the policy
processing result. See [PEM-1-TS] for the normative use of Diameter.
PEEM requirements are documented in [PEEM-RD] and PEEM Architecture
is documented in [PEEM-AD].
The Diameter realization of this application assumes the use of the
Diameter Base protocol, as per RFC 3588, and extends it only for a
specific application using a vendor-id (PEN), a vendor-specific
application ID, a new Command Code (314), and a new AVP defined in
the vendor-specific namespace. Input to policy processing are being
passed through a new AVP, and policy results are being passed through
a combination of the same new AVP, and the Experimental-Result AVP.
2. Terminology
The base Diameter specification (Section 1.4 of [RFC3588]) defines
most of the terminology used in this document. Additionally, the
terms and acronyms defined in [PEM-1-TS] are used in this document.
3. Diameter Policy Processing Application
A detailed description of the Diameter Policy Processing Application
can be found in Section 5.4.1 of the Policy Evaluation, Enforcement
and Management Callable Interface (PEM-1) Technical Specification
[PEM-1-TS].
4. Security Considerations
This document describes the Diameter Policy Processing Application.
It builds on top of the Diameter Base protocol and the same security
considerations described in RFC 3588 [RFC3588] are applicable to this
document. No further extensions are required beyond the security
mechanisms offered by RFC 3588.

5. IANA Considerations
This section provides guidance to the Internet Assigned Numbers
Authority (IANA) regarding registration of values related to the
Diameter protocol, in accordance with BCP 26 [RFC2434].
This document defines values in the namespaces that have been created
and defined in the Diameter Base [RFC3588]. The IANA Considerations
section of that document details the assignment criteria. Values
assigned in this document, or by future IANA action, must be
coordinated within this shared namespace.
5.1. Command Codes
This specification assigns the value 314 from the Command Code
namespace defined in [RFC3588]. See Section 5.4.1.3.1 of [PEM-1-TS]
to see how the command code is used.
IANA has made the following assignment in the "Authentication,
Authorization, and Accounting (AAA) Parameters" registry, in the sub-
registry "Command Codes".
Code Value Name Reference
-------------- ------------------------------- ---------
314 PDR / PDA [RFC5224]
5.2. AVP Codes
This specification uses the value 1 for the Policy-Data AVP, in the
OMA Vendor-ID (PEN) AVP namespace. See Section 5.4.1.3.3 of
[PEM-1-TS] for the assignment of the namespace in this specification.
5.3. Application Identifier
This specification uses the value 16777243 in the Application
Identifier namespace as registered in IANA for the Policy Processing
Application. See Section 5.4.1.3 of [PEM-1-TS] for more information.
6. Acknowledgements
The author would like to thank Dan Romascanu and Hannes Tschofenig
for their help and support.
Finally, the author would like to thank Alcatel-Lucent, as most of
the effort put into this document was done while he was in their
employ.
