Abstract

  This document registers a set of IANA Diameter Command Codes to be
  used in new vendor-specific Diameter applications defined for the
  Third Generation Partnership Project (3GPP) Evolved Packet System
  (EPS).  These new Diameter applications are defined for Mobile
  Management Entity (MME)- and Serving GPRS (General Packet Radio
  Service) Support Node (SGSN)-related interfaces in in the
  architecture for the Evolved 3GPP Packet Switched Domain, which is
  also known as the Evolved Packet System (EPS).

1.  Introduction

  The Third Generation Partnership Project (3GPP) is defining the
  Evolved 3GPP Packet Switched Domain - also known as the Evolved
  Packet System (EPS).  As part of this architecture, the interfaces
  based on the Diameter protocol [RFC3588] require the definition of
  two new Diameter applications.

  As defined in [TS29.272], the 3GPP S6a/S6d application (vendor-
  specific application id: 16777251) enables the transfer of
  subscriber-related data between the Mobile Management Entity (MME)
  and the Home Subscriber Server (HSS) on the S6a interface and between
  the Serving GPRS Support Node (SGSN) and the Home Subscriber Server
  (HSS) on the S6d interface.

  Also defined in [TS29.272], the 3GPP S13/S13' application (vendor-
  specific application id: 16777252) enables the Mobile Equipment
  Identity check procedure between the Mobile Management Entity (MME)
  and the Equipment Identity Register (EIR) on the S13 interface and
  between the Serving GPRS Support Node (SGSN) and the Equipment
  Identity Register (EIR) on the S13' interface.

  Both Diameter applications are defined under the 3GPP vendor-id
  "10415".  This document defines the assigned values of the command
  codes used in these applications.

2.  Terminology

  The base Diameter specification (Section 1.3 of [RFC3588]) defines
  most of the terminology used in this document.  Additionally, the
  terms and acronyms defined in [TS29.272] are used in this document.

3.  Command Codes

  The 3GPP S6a/S6d application described in Section 5 of [TS29.272]
  requires the allocation of command code values for the following
  command pairs:

  o  3GPP-Update-Location-Request/Answer (ULR/ULA)

  o  3GPP-Cancel-Location-Request/Answer (CLR/CLA)

  o  3GPP-Authentication-Information-Request/ Answer (AIR/AIA)

  o  3GPP-Insert-Subscriber-Data-Request/Answer (IDR/IDA)

  o  3GPP-Delete-Subscriber-Data-Request/Answer (DSR/DSA)

  o  3GPP-Purge-UE-Request/Answer (PUR/PUA)

  o  3GPP-Reset-Request/Answer (RSR/RSA)

  o  3GPP-Notify-Request/Answer (NOR/NOA)

  The 3GPP S13/S13 application described in Section 6 of [TS29.272]
  requires the allocation of a command code value for the following
  command pair:

  o  3GPP-ME-Identity-Check-Request/Answer (ECR/ECA)

4.  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 [RFC5226].

  This document defines values in the namespace that has been defined
  in the Diameter base specification [RFC3588].  Section 11 of
  [RFC3588] (that document's IANA Considerations) details the
  assignment criteria.  IANA allocated the following command code
  values:

5.  Security Considerations

  This document describes command codes used in applications that build
  on top of the Diameter base protocol and the same security
  considerations described in [RFC3588] are applicable to this
  document.  No further extensions are required beyond the security
  mechanisms offered by [RFC3588].

6.  Acknowledgements

  We would like to thank the 3GPP CT4 delegates, Victor Fajardo, and
  Glen Zorn for their review and comments.  We would also like to thank
  Dan Romascanu for volunteering to be AD sponsor and Hannes Tschofenig
  for volunteering to be Document Shepherd.
