Additional Identifier Types are proposed for use with
the Mobile Node Identifier Option for MIPv6 (RFC 4283).
The Mobile Node Identifier Option for MIPv6
has proved to be a popular design tool for providing
identifiers for mobile nodes during authentication procedures
with AAA protocols such as Diameter .
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 itself. 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.
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.
IPv6 Address
IMSI
P-TMSI
EUI-48 address
EUI-64 address
GUTI
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.
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
