The Emergency Context Resolution with Internet Technologies (ecrit) working group in the Real-time Applications and Infrastructure Area of the IETF is undergoing rechartering. The IESG has not made any determination yet. The following draft charter was submitted, and is provided for informational purposes only. Please send your comments to the IESG mailing list (iesg at ietf.org) by 2013-12-02. Emergency Context Resolution with Internet Technologies (ecrit) ------------------------------------------------ Current Status: Active WG Chairs: Marc Linsner <marc.linsner@cisco.com> Roger Marshall <rmarshall@telecomsys.com> Assigned Area Director: Richard Barnes <rlb@ipv.sx> Mailing list Address: ecrit@ietf.org To Subscribe: https://www.ietf.org/mailman/listinfo/ecrit Archive: http://www.ietf.org/mail-archive/web/ecrit/ Charter: In a number of areas, the public switched telephone network (PSTN) has been configured to recognize an explicitly specified number (usually one that is short and easily memorized) as a request for emergency services. These numbers (e.g., 911, 112) are related to an emergency service context and depend on a broad, regional configuration of service contact methods and a geographically-constrained approach for 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 an association of both the physical location of the originating device along with appropriate call routing to an emergency service center. Calls placed using Internet technologies do not use the same systems mentioned above to achieve those same goals, and the common use of overlay networks and tunnels (either as VPNs or for mobility) makes meeting these goals even more challenging. There are, however, Internet technologies available to manage location and to perform call routing. This working group has described where and how these mechanisms may be used. The group specified how location data and call routing information are used to enable communication between a user and a relevant emergency response center [RFC6443,RFC6444]. Though the term "call routing" is used, it should be understood that some of the mechanisms described might be used to enable other types of media streams. Beyond human initiated emergency call request mechanisms, this group will develop new methods to enable non-human-initiated requests for emergency assistance, such as sensor initiated emergency requests. The working group will also address topics required for the operation of emergency calling systems, such as: authentication of location, management of the service URN namespace, augmented information that could assist emergency call takers or responders. Explicitly outside the scope of this group is the question of pre- emption or prioritization of emergency services traffic in the network. 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. While this group anticipates a close working relationship with groups such as NENA, EENA, 3GPP, and ETSI , any solution presented must be general enough to be potentially useful in or across multiple regions or jurisdictions, and it must be possible to use without requiring a single, central authority. Further, it must be possible for multiple delegations within a jurisdiction to be handled independently, things such as call routing for specific emergency types, media types, language contents, etc., may be routed differently depending on established policies and availability. This working group will address privacy and security concerns within its documents.
