Perkins & Devarapalli Expires April 28, 2011 [Page 1] Internet-Draft MN Identifier Types for RFC 4283 October 2010 1. Introduction The Mobile Node Identifier Option for MIPv6 [2] has proved to be a popular design tool for providing identifiers for mobile nodes during authentication procedures with AAA protocols such as Diameter [4]. To date, only a single type of identifier has been specified, namely the MN NAI. Other types of identifiers are in common use, and even referenced in RFC 4283. In this document, we propose adding some basic types that are commonly in use in various telecommunications standards, including the IMSI, P-TMSI, IMEI, GUTI, and IEEE MAC-layer addresses. In addition, we include the IPv6 address itself as a legitimate mobile node identifier. Perkins & Devarapalli Expires April 28, 2011 [Page 2] Internet-Draft MN Identifier Types for RFC 4283 October 2010 2. New Mobile Node Identifier Types The following types of identifiers are commonly used to identify mobile nodes. For each type, references are provided with full details on the format of the type of identifer. o IPv6 Address [1] o IMSI [5] o P-TMSI [5] o EUI-48 address [6] o EUI-64 address [6] o GUTI [5] Perkins & Devarapalli Expires April 28, 2011 [Page 3] Internet-Draft MN Identifier Types for RFC 4283 October 2010 3. Security Considerations This document does not introduce any security mechanisms, and does not have any impact on existing security mechanisms. Insofar as the selection of a security association may be dependent on the exact form of a mobile node identifier, additional specification may be necessary when the new identifier types are employed with the general AAA mechanisms for mobile node authorizations. Perkins & Devarapalli Expires April 28, 2011 [Page 4] Internet-Draft MN Identifier Types for RFC 4283 October 2010 4. IANA Considerations The new mobile node identifier types defined in the document should be assigned values from the "Mobile Node Identifier Option Subtypes" registry. The following values should be assigned. New Mobile Node Identifier Types +-----------------+------------------------+ | Identifier Type | Identifier Type Number | +-----------------+------------------------+ | IPv6 Address | 2 | | | | | IMSI | 3 | | | | | P-TMSI | 4 | | | | | EUI-48 address | 5 | | | | | EUI-64 address | 6 | | | | | GUTI | 7 | +-----------------+------------------------+ Table 1 See Section 2 for details about the identifer types.
