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.

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]

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.

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 |
+-----------------+------------------------+

See Section 2 for details about the identifer types.
