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].

§1Evolved Packet System Architecture
The 3GPP Evolved Packet System (EPS) is the architecture for fourth-generation (4G LTE) mobile networks. Two critical network elements are the Mobile Management Entity (MME), which controls user authentication and mobility, and the Serving GPRS Support Node (SGSN), which routes data for legacy connections. Both interact with the Home Subscriber Server (HSS), which stores subscriber information like which services are allowed.
The interfaces between these elements (called S6a, S6d, S13, and S13') use the Diameter protocol. Because Diameter is extensible, each application using it needs unique command codes to avoid conflicts.
In a 4G network, the phone connects to an MME, which asks the HSS if the customer is allowed on the network. They use Diameter to ask questions, but they need special codes so the answers don't get confused with other questions.
§2Two Key 3GPP Applications
The S6a/S6d application (vendor ID 16777251) handles subscriber data. The MME or SGSN can request update-location information (commands 316), cancellation-location information (317), authentication data (318), and insertion or deletion of subscriber data (319-320). Commands for purging (321), resetting (322), and notifications (323) also transfer subscriber state.
The S13/S13' application (vendor ID 16777252) handles Mobile Equipment (ME) identity checking. The Mobile Equipment Identity Check Request/Answer (command 324) lets the MME or SGSN verify with the Equipment Identity Register that a device is not blacklisted (e.g., for theft or fraud).
The S6 interface asks "what can this customer do?" The S13 interface asks "is this phone stolen or blacklisted?"
§3IANA Command Code Allocations
RFC 5516 registers nine command code values in the 3GPP vendor namespace (10415). Commands 316 through 324 are allocated as pairs (request and answer) with specific abbreviations used in 3GPP specifications. For example, code 316 handles Update-Location-Request (ULR) and Update-Location-Answer (ULA). Each command is defined in 3GPP Technical Specification TS 29.272, which provides the ABNF and semantics for the Diameter messages.
IANA assigns nine numbers, one pair for each type of question the phone company needs to ask. Each number has a name like ULR (Update-Location-Request).
