Hi,
For RFID we refer to the EPC standards.
"The /Electronic Product Code/ (EPC) is an identification scheme for
universally identifying physical objects by using Radio Frequency
Identification (RFID) tags.
The standardized EPC tag encoding consists of an EPC Identifier that
uniquely identifies an individual object, and may also include a
filter value if the filter is needed to enable effective and efficient
reading of the EPC tags. The EPC Identifier is a meta-coding scheme
designed to support the needs of various industries by accommodating
existing coding schemes where possible and by defining new schemes
where necessary."
"EPC supports several encoding systems or schemes including GID
(Global Identifier), SGTIN (Serialized Global Trade Item Number), SSCC
(Serial Shipping Container), GLN (Global Location Number), GRAI
(Global Returnable Asset Identifier), DOD (Department of Defense) and
GIAI (Global Individual Asset Identifier).
For each scheme except GID, there are two variations—a 64-bit scheme
(for example, GLN-64) and a 96-bit scheme (GLN-96). GID has only a
96-bit scheme.
Within each scheme, an EPC identifier can be represented in a binary
form or other forms such as URI ..etc".
May be we need some subtyping.
Cheers,
Hakima

I do not know the answer for this question. I assumed DOD-96 is a
mandated standard for RFID encoding, but looks like there are other
formats like GID-96 ..etc. May be this may end up needing subtypes. We
can defer this question to Hakima and learn some details on this, she
seems to have written many books on RFID.

Hello Sri,
Is the DoD-96 identifier for a special kind of RFID, or is it
valid for all the RFID devices that would be of interest?

Hi Hakima,
That is a good idea. We should register a type for the Dod-96

Hello Folks,
Do you think that considering specific but needed technologies for
moving objects in Internet of Things such as RFID (Radio

relevent to Charlie's current draft and the efforts related to MNID?

<Changing the subject line to reflect the MNId discussion>
Marco,
Thinking further on the complementary identifier option.
- There is already the link-layer identifier option that can be used for
carrying the Mac address
- IMEI and MSISDN are already defined in 29.275 as a 3GPP VSE's
In some sense, the complementary identifiers are already present.

I do not see a reason why multiple MN-Id instances need to be

consideration, when to use what type of identifiers.
Assuming the backend system can tie all the MN-Id's to a single
subscription, any presented identifier can be sufficient for the
gateway
to do the BCE lookup.
If multiple instances can be present, then we need to deal with
more error
cases. Is that really needed ?
I am wondering if it would not be more appropriate to go for a
different
container option to carry such information. Something like a
complementary identifier option.
Sounds interesting. Are you suggesting we leave the current MN-ID
as it
is, but use a new complementary option ? But, if the requirement is
for a
Mac based identifiers, what will be there in the current MN-Id
option ? We
still need to have identifier there ?

Operation is clear to me in case a single MNID is present in a

flexible to choose from different sub-types. If multiple MNIDs
with
different sub-types are present in
a single message, which one should e.g. the LMA take for the BC
lookup..
No big problem to solve, but
to be considered in implementations.
If the reason for multiple present MNIDs with different
sub-types is to
do other things than identifying
the node or using the ID as key for a lookup, I am wondering if
it would
not be more appropriate
to go for a different container option to carry such

Something like a complementary
identifier option.

Hello Charlie,
Agree with that. MN-Id as its defined today is a logical
identifier. It
does not
require the identifier to be bound to a physical device or
a interface
identity.
But, we have clearly seen requirements where the need is
for generating
identifiers based on some physical identifiers. Those
physical
identifiers include
IMSI, MSISDN, IMEI, MAC ..etc. If we can define a type for
each of the
source
and the rules for generating MN-ID based using those
sources, the sender
and
receiver will have clear guidance on how to use the spec.
Some pointers,
explanation and examples for each of those identifiers will
greatly help
avoid
inter-op issues.

Sri

Hello folks,
I think it's best to consider the MNID as simply living
in a space of
identifiers, and not worry too much about whether it's
a logical
identifier or a physical identifier. If the former,
then somewhere
(perhaps below the network layer) the logical
identifier has been bound
to something in the physical interface, but that's not
our problem.
The number space for types of MNIDs is likely to stay
pretty empty, so
I'd say we could add as many types as would be
convenient for the
software designers. So, we could conceivably have
several MNIDs
defined that all "looked like" NAIs (which, themselves,
"look like"
FQDNs).

Yes. Currently, the MNID is if the nai format and
is overloaded. The
MNID in 3GPP specs is the IMSI-NAI (IMSI@REALM),
its based on the
IMSI. Ex:
"<IMSI>@epc.mnc<MNC>.mcc<MCC>.3gppnetwork.org²
We also have MAC48@REALM;
We also have approaches to transform MAC to Pseudo
IMSI, and then
carry IMSI-NAI as the MN-ID.
So, we need unique sub-types for each of the
types/sources.
MN-Id based on IMSI, MSISDN, IMEI, MAC ..
Also, do we need to distinguish between IMSI and
IMSI-NAI ?

It seems the MNID is somehow overloaded to
carry both, node-specific
IDs, e.g. MAC, as well as subscriber IDs,
which is the IMSI.
There may be value in adding the IMEI to the
list of possible types
of node-specific IDs.

Two more comments.
4.) I'd also use sub-type value of (2) for
IMSI. Just to align with
the sub-types defined for MN Id defined
for ICMP. I suspect there
are some implementations already using
sub-type (2). Please see
the other thread.
5.) For each of the sub-types, we need text
including examples and
some
explanation on how they are used.

Hi Charlie,
This is good. Thanks.
1.) If EUI-48 and EUI-64 addresses are
derived of a 48-bit IEEE
802.2
address, why do we need to two
sub-types ? Why not have just one
sub-type for mac based identifiers ?
2.) Sub type value (1) is currently
used. Its currently overloaded
for
IMSI-NAI (3GPP specs) and generic NAI
based identifiers. Given the
definition of new sub-types, we need
some text explaining the
motivation
3.) Proposed Sub-type value of (2) for
IPv6 address. What exactly
is
this ? Are these CGA-based IPv6
addresses ?
