Re: [stir] Robocall Strike Force

["DOLLY, MARTIN C" <[e-mail]>]

Tony,

For deployment in the USA, this ITU work would be totally useless.

The ATIS - SIP Forum is has a profile of the IETF STIR RFC drafts in the SHAKEN Framework document.
Further, SHAKEN telecom industry framework - Signature-based Handling of Asserted Information using Tokens

1.      Defines the architecture and NNI dependencies around the usage of the PASSporT and 4474bis based framework

2.      Defines the security model around management and usage of certificates used to sign and assert caller identity information

In addition, there is a Display Framework document, that defines the requirements for signaling the verification information from the network to the user device and the requirements for what is displayed on the user device independent of technology.

Service Requirements to support the above is being brought into the 3GPP SA1 meeting in San Francisco next week, 8/22-26 (Being led by Greg Schumacher, Sprint).

I will be bring in a discussion paper and CRs into the October CT1 meeting in China with the support of Nokia and Ericsson (and hopefully the other USA companies).

WRT display  on the user device, there will be a combination of vendors getting requirements based on the ATIS-SIP Forum Display Framework given to them as part of ecosystem participation in the FCC Strike Force and/or direct requirements from carriers. In addition, further documentation to in GSMA, Cable Labs, etc... specifications may/will occur.

Up to now, the coordination has been with the ATIS-SIP Forum co-chairs/leaders and moving forward with the FCC Strike Force Authentication Committee (co-chairs Chris Wendt and myself, so there the transition should be seamless)

With the above work plan I do not see a role for the ITU on the Caller ID Spoofing.

Hi Martin et al.,

It is worth noting that for the
upcoming SG17 meeting, China's
MIIT, China Unicom, and China mobile
have proposed a new work item that
is substantially related to stir work.
Indeed, the proposal contains a useful
comprehensive overview of related
SDO activities, including stir, and
a gap analysis.

I expect that the usdel to the meeting
would appreciate any views from the
Task Force and stir participants on
the contribution.  In addition, how does
stir and the IETF anticipate collaborating
with SG17 and the other SDOs going forward?
The NWI seems almost certain to get approved,
and may well be before WTSA 2016.

best,
