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] 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]. 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]) 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 application described in [TS29.272] requires the allocation of command code values for the following command pairs: o Update-Location-Request/Answer (ULR/ULA) o Cancel-Location-Request/Answer (CLR/CLA) o Authentication-Information-Request/ Answer (AIR/AIA) o Insert-Subscriber-Data-Request/Answer (IDR/IDA) o Delete-Subscriber-Data-Request/Answer (DSR/DSA) o Purge-UE-Request/Answer (PUR/PUA) o Reset-Request/Answer (RSR/RSA) o Notify-Request/Answer (NOR/NOA) The 3GPP S13 application described in [TS29.272] requires the allocation of a command code value for the following command pair: o ME-Identity-Check-Request/Answer (ECR/ECA) Jones & Morand Expires July 3, 2009 [Page 3] Internet-Draft 3gpp-eps-command-codes December 2008 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] (IANA Considerations) details the assignment criteria. IANA is requested to allocate the following command code values: +---------------------------------------------------------------------+ | Code Command Name Abbreviation Defined in | +---------------------------------------------------------------------+ | tbd Update-Location-Request ULR 3GPP TS 29.272 | | tbd Update-Location-Answer ULA 3GPP TS 29.272 | | tbd Cancel-Location-Request CLR 3GPP TS 29.272 | | tbd Cancel-Location-Answer CLA 3GPP TS 29.272 | | tbd Authentication-Information-Request AIR 3GPP TS 29.272 | | tbd Authentication-Information-Answer AIA 3GPP TS 29.272 | | tbd Insert-Subscriber-Data-Request IDR 3GPP TS 29.272 | | tbd Insert-Subscriber-Data-Answer IDA 3GPP TS 29.272 | | tbd Delete-Subscriber-Data-Request DSR 3GPP TS 29.272 | | tbd Delete-Subscriber-Data-Answer DSA 3GPP TS 29.272 | | tbd Purge-UE-Request PUR 3GPP TS 29.272 | | tbd Purge-UE-Answer PUA 3GPP TS 29.272 | | tbd Reset-Request RSR 3GPP TS 29.272 | | tbd Reset-Answer RSA 3GPP TS 29.272 | | tbd Notify-Request NOR 3GPP TS 29.272 | | tbd Notify-Answer NOA 3GPP TS 29.272 | | tbd ME-Identity-Check-Request ECR 3GPP TS 29.272 | | tbd ME-Identity-Check-Answer ECA 3GPP TS 29.272 | +---------------------------------------------------------------------+ 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] 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 Jones & Morand Expires July 3, 2009 [Page 4] Internet-Draft 3gpp-eps-command-codes December 2008 Glen Zorn for their review and comments.
