A new IETF working group has been proposed in the Transport Area. The
IESG has not made any determination as yet. The following description
was submitted, and is provided for informational purposes only. Please
send your comments to the IESG mailing list (iesg@ietf.org) by February

Emergency Context Resolution with Internet Technologies (ecrit)
================================================================

Currect Status: Proposed Working Group

Description of Working Group:

In a number of areas, the public switched telephone network (PSTN) has
been configured to recognize an explicitly specified number (commonly
one that is short and easily memorized) as a call for emergency
services.  These numbers (e.g. 911, 112) relate to an emergency service
context and depend on a broad, regional configuration of service contact
methods and a geographically-constrained context of service delivery.
These calls are intended to be delivered to special call centers
equipped to manage emergency response. Successful delivery of an
emergency service call within those systems requires both an association
of the physical location of the originator with an appropriate emergency
service center and call routing to deliver the call to the center.

Calls placed using Internet technologies do not use the same systems to
achieve those goals, and the common use of overlay networks and tunnels
(either as VPNs or for mobility) makes meeting them more challenging.
There are, however, Internet technologies available to describe location
and to manage call routing.  This working group will describe when these
may be appropriate and how they may be used.
Explicitly outside the scope of this group is the question of
pre-emption or prioritization of emergency services traffic. This group
is considering emergency services calls which might be made by any user
of the Internet, as opposed to government or military services that may
impose very different authentication and routing requirements.

The group will show how the availability of location data and call
routing information at different steps in session setup would enable
communication between a user and a relevant emergency response center.
Though the term "call routing" is used in this document, it should be
understood that some of the mechanisms which will be described might be
used to enable other types of media streams. Video and text messaging,
for example, might be used to request emergency services.

While this group anticipates a close working relationship with groups
such as NENA and ETSI EMTEL, any solution presented must be useful
regardless of jurisdiction, and it must be possible to use without a
single, central authority.  Further, it must be possible for multiple
delegations within a jurisdiction to be handled independently, as call
routing for specific emergency types may be independent.

This working group cares about privacy and security concerns, and will
address them within its documents.
