Abstract

This document registers a set of IANA Applications and Diameter Command Codes to be used in new vendor-specific Diameter applications defined for the Worldwide Interoperability for Microwave Access (WiMAX). These new Diameter applications are defined for the interaction of the Access Serving Network Gateway (ASNGW) with the AAA and the Policy and Charging Control infrastructure in the Connectivity Serving Network (CSN) and between the Home Agent (HA) and AAA servers. Applications and related commands are also defined to support Location Based Services.

1.  Introduction

Release 1.0 of the WiMAX Forum network architecture utilizes RADIUS [RFC2865] (Rigney, C., Willens, S., Rubens, A., and W. Simpson, “Remote Authentication Dial In User Service (RADIUS),” June 2000.) based Authentication, Authorization and Accounting (AAA) protocols. Release 1.5 introduce Diameter [RFC3588] (Calhoun, P., Loughney, J., Guttman, E., Zorn, G., and J. Arkko, “Diameter Base Protocol,” September 2003.) AAA protocols.

As part of this architecture, the interfaces based on the Diameter protocol requires the definition of the following Diameter applications:

WiMAX Network Access Authentication and Authorization Diameter Application(WNAAADA)

This application authenticates, authorizes, network access of devices between the ASN-GW and the Diameter Server in the CSN. Part of the authorization includes IP and QoS bootstrapping.

WiMAX Network Accounting Diameter Application(WNADA)

This application is used for accounting purposes between the ASN-GW or Home Agent and the Accounting server.

WiMAX MIP4 Diameter Application(WM4DA)

This application is used to authenticate and authorize Mobile IPv4 service between the Home Agent and the Diameter server.

WiMAX MIP6 Diameter Application(WM6DA)

This application is used to authenticate and authorize Mobile IPv6 service between the Home Agent and the Diameter server.

WiMAX DHCP Diameter Application(WDDA)

This application is used to obtain keys used to secure DHCP interactions between the DHCP Relay and the DHCP Server.

WiMAX-Location-Authentication-Authorization Diameter Application(WLAADA)

This application is used to authenticate and authorize location requester seeking location information about a specific WiMAX devices.

WiMAX-Location-Authentication-Authorization Diameter Application(WLAADA)

This application is used to authenticate and authorize location requester seeking location information about a specific WiMAX devices. As well, the application supports command for fetching measurement reports from the ASN.

WiMAX-Policy-and-Charging-Control-R3-Policies Diameter Application(WiMAX PCC-R3-P)

This application is used for the policy and charging control in a WiMAX network when WiMAX PCRF and ASN are interacting.

WiMAX-Policy-and-Charging-Control-R3-OFfline-Charging Diameter Application(WiMAX PCC-R3-OFC)

This application is used for Diameter based offline charging in WiMAX networks when the ASN interacts with the CSN.

WiMAX-Policy-and-Charging-Control-R3-OFfline-Charging-Prime Diameter Application(WiMAX PCC-R3-OFC')

This application is used for Diameter based offline charging in WiMAX networks when AAA provides accounting records to an OFCS.

WiMAX-Policy-and-Charging-Control-R3-Online-Charging Diameter Application(WiMAX PCC-R3-OC)

This application is used for Diameter based online charging in WiMAX networks when the ASN interacts with the Online Charging System (OCS).

2.  Terminology

The base Diameter specification (Section1.4 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.

3.  WiMAX Network Access Authentication and Authorization Diameter Application(WNAAADA)

The WiMAX Network Access Authentication and Authorization Diameter application requires the allocation of command code values for the following command pairs:

• WiMAX-Diameter-EAP-Request/Answer (WDER/WDEA)
• WiMAX-Change-of-Authorization-Request/Answer (WCAR/WCAA)
• WiMAX-Reauthentication-Request/Answer (WRAR/WRAA)
• WiMAX-Session-Termination-Request/Answer (WSTR/WSTA)
• WiMAX-Abort-Session-Request/Answer (WASR/WASA)

4.  WiMAX Network Accounting Diameter Application(WNADA)

The WiMAX Network Accounting Diameter Application re-uses the commands defined in Diameter Base [RFC3588] (Calhoun, P., Loughney, J., Guttman, E., Zorn, G., and J. Arkko, “Diameter Base Protocol,” September 2003.).

5.  WiMAX MIP4 Diameter Application(WM4DA)

The WiMAX MIP4 Diameter application requires the allocation of command code values for the following command pairs:

• WiMAX-Home-Agent-IPv4-Request/Answer (WHA4R/WHA4A)

6.  WiMAX MIP6 Diameter Application(WM6DA)

The WM6DA application requires the allocation of command code values for the following command pairs:

• WiMAX-Home-Agent-IPv6-Request/Answer (WHA6R/WHA6A)

7.  WiMAX DHCP Diameter Application(WDDA)

The WiMAX DHCP Diameter application requires the allocation of command code values for the following command pairs:

• WiMAX-DHCP-Request/Answer (WDHCPR/WDHCPA)

8.  WiMAX Location Authentication Authorization Diameter Application(WLAADA)

The WiMAX-Location-Authentication-Authorization Diameter Application requires the allocation of command code values for the following command pairs:

• WiMAX-LAA-Request/Answer (WLAAR/WLAA)
• WiMAX-Location-Accounting-Request/Answer (WLACR/WLACA)
• WiMAX-Location-Measurement-Query-Request/Answer (WLMQR/WLMQA)

9.  WiMAX Policy and Charging Control R3 Policies Diameter Application(WiMAX PCC-R3-P)

The WiMAX Policy and Charging Control R3 Policies Diameter Application is based on 3GPP Gx and reuses the commands defined in Diameter Credit-Control Application [RFC4006] (Hakala, H., Mattila, L., Koskinen, J-P., Stura, M., and J. Loughney, “Diameter Credit-Control Application,” August 2005.) respectively commands defined in Diameter Base [RFC3588] (Calhoun, P., Loughney, J., Guttman, E., Zorn, G., and J.

10.  WiMAX Policy and Charging Control R3 OFfline Charging Diameter Application(WiMAX PCC-R3-OFC)

The WiMAX Policy and Charging Control R3 Offline Charging Diameter Application reuses the commands defined in Diameter Base [RFC3588] (Calhoun, P., Loughney, J., Guttman, E., Zorn, G., and J. Arkko, “Diameter Base Protocol,” September 2003.).

11.  WiMAX Policy and Charging Control R3 OFfline Charging Prime Diameter Application(WiMAX PCC-R3-OFC')

The WiMAX Policy and Charging Control R3 Offline Charging Diameter Prime Application reuses the commands defined in Diameter Base [RFC3588] (Calhoun, P., Loughney, J., Guttman, E., Zorn, G., and J. Arkko, “Diameter Base Protocol,” September 2003.).

12.  WiMAX Policy and Charging Control R3 Online Charging Diameter Application(WiMAX PCC-R3-OC)

The WiMAX Policy and Charging Control R3 Online Charging Diameter Application reuses the commands defined in Diameter Credit-Control Application [RFC4006] (Hakala, H., Mattila, L., Koskinen, J-P., Stura, M., and J. Loughney, “Diameter Credit-Control Application,” August 2005.) respectively commands defined in Diameter Base [RFC3588] (Calhoun, P., Loughney, J., Guttman, E., Zorn, G., and J. Arkko, “Diameter Base Protocol,” September 2003.).

13.  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 Vendor Specific Application code values as per section 11.3 of [RFC3588] (Calhoun, P., Loughney, J., Guttman, E., Zorn, G., and J. Arkko, “Diameter Base Protocol,” September 2003.) :

14.  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.).
