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 MME and SGSN related interfaces in the Release 8 architecture.

1.  Introduction

The Third Generation Partnership Project (3GPP) is defining the Evolved Packet System (EPS) as part of their Release 8 architecture. As part of this architecture, the interfaces based on the Diameter protocol [RFC3588] (Calhoun, P., Loughney, J., Guttman, E., Zorn, G., and J. Arkko, “Diameter Base Protocol,” September 2003.) require the definition of two new Diameter applications: the 3GPP S6a application (vendor-specific application id: 1677251) and 3GPP S13 application (vendor-specific application id: 1677252), both defined under the 3GPP vendor-id "10415". These Diameter applications are described in [TS29.272] (3rd Generation Partnership Project, “3GPP TS 29.272 V8.0.0; Technical Specification Group Core Network and Terminals; Evolved Packet System; MME and SGSN Related Interfaces Based on Diameter Protocol (Release 8),” September 2008.). This document defines the assigned values of the command codes used in these applications.

2.  Terminology

The base Diameter specification (Section 1.4 of [RFC3588] (Calhoun, P., Loughney, J., Guttman, E., Zorn, G., and J. Arkko, “Diameter Base Protocol,” September 2003.)) defines most of the terminology used in this document. Additionally, the terms and acronyms defined in [TS29.272] (3rd Generation Partnership Project, “3GPP TS 29.272 V8.0.0; Technical Specification Group Core Network and Terminals; Evolved Packet System; MME and SGSN Related Interfaces Based on Diameter Protocol (Release 8),” September 2008.) are used in this document.

3.  Command Codes

The 3GPP S6a application described in [TS29.272] (3rd Generation Partnership Project, “3GPP TS 29.272 V8.0.0; Technical Specification Group Core Network and Terminals; Evolved Packet System; MME and SGSN Related Interfaces Based on Diameter Protocol (Release 8),” September 2008.) requires the allocation of command code values for the following command pairs:

• Update-Location-Request/Answer (ULR/ULA)
• Cancel-Location-Request/Answer (CLR/CLA)
• Authentication-Information-Request/ Answer (AIR/AIA)
• Insert-Subscriber-Data-Request/Answer (IDR/IDA)
• Delete-Subscriber-Data-Request/Answer (DSR/DSA)
• Purge-UE-Request/Answer (PUR/PUA)
• Reset-Request/Answer (RSR/RSA)
• Notify-Request/Answer (NOR/NOA)

The 3GPP S13 application described in [TS29.272] (3rd Generation Partnership Project, “3GPP TS 29.272 V8.0.0; Technical Specification Group Core Network and Terminals; Evolved Packet System; MME and SGSN Related Interfaces Based on Diameter Protocol (Release 8),” September 2008.) requires the allocation of a command code value for the following command pair:

• 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] (Narten, T. and H. Alvestrand, “Guidelines for Writing an IANA Considerations Section in RFCs,” May 2008.).

This document defines values in the namespace that has been defined in the Diameter Base specification [RFC3588] (Calhoun, P., Loughney, J., Guttman, E., Zorn, G., and J. Arkko, “Diameter Base Protocol,” September 2003.). Section 11 of [RFC3588] (Calhoun, P., Loughney, J., Guttman, E., Zorn, G., and J. Arkko, “Diameter Base Protocol,” September 2003.) (IANA Considerations) details the assignment criteria.

IANA is requested to allocate the following command code values:

5.  Security Considerations

This document describes command codes used in applications which build on top of the Diameter base protocol and the same security considerations described in [RFC3588] (Calhoun, P., Loughney, J., Guttman, E., Zorn, G., and J. Arkko, “Diameter Base Protocol,” September 2003.) are applicable to this document. No further extensions are required beyond the security mechanisms offered by [RFC3588] (Calhoun, P., Loughney, J., Guttman, E., Zorn, G., and J. Arkko, “Diameter Base Protocol,” September 2003.).
