  • Dept of Transportation, Research and Innovative Technology Administraiton, Next Generation 911
  • " The Nation's current 9-1-1 system is designed around telephone technology and cannot handle the text, data, images and video that are increasingly common in personal communications and critical to future transportation safety and mobility advances.The Next Generation 9-1-1 (NG 9-1-1) initiative will establish the foundation for public emergency communications services in a wireless mobile society. "

  • NENA-VON Coalition Agreement: In December 2003, NENA, the VON Coalition and a number of major companies involved in providing voice-over-IP equipment or services agreed on a set of action items:

  • For service to customers using phones that have the functionality and appearance of conventional telephones, 9-1-1 emergency services access will be provided (at least routing to a Public Safety Access Point (PSAP) 10-digit number) within a reasonable time (three to six months), and prior to that time inform customers of the lack of such access.
  • When a communications provider begins selling in a particular area, it should discuss with the local PSAPs or their coordinator the approach to providing access. This obligation does not apply to any “roaming” by customers.
  • Support for current NENA and industry work towards an interim solution that includes (a) delivery of 9-1-1 call through the existing 9-1-1 network, (b) providing callback number to the PSAP, and (c) in some cases, initial location information.
  • Support for current NENA and industry work towards long-term solutions that include (a) delivery of 9-1-1 calls to the proper PSAP, (b) providing callback number/ recontact information to the PSAP, (c) providing location of caller; and (d) PSAPs having direct IP connectivity.
  • Support for an administrative approach to maintaining funding of 9-1-1 resources at a level equivalent to those generated by current or evolving funding processes.
  • Development of consumer education projects involving various industry participants and NENA public education committee members to create suggested materials so that consumers are fully aware of 9-1-1 capabilities and issues.

  • "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."

  • IETF GeoPriv Working Group
  • "As more and more resources become available on the Internet, some applications need to acquire geographic location information about certain resources or entities. These applications include navigation, emergency services, management of equipment in the field, and other location-based services.... The primary task of this working group will be to assess the the authorization, integrity and privacy requirements that must be met in order to transfer such information, or authorize the release or
    representation of such information through an agent. ... This WG won't develop technology to support any particular regulatory requirement [e.g. E.911] but will provide a framework that might be used for private/secure definition of such technologies by other bodies.

  • Internet Emergency Preparedness
  • "the working group will devlop a Requirements for Internet Emergency Preparedness in the Internet RFC which will detail the specific functions and technologies needed to provide support for Emergency Preparedness systems in the Internet. The working group may also develop a Framework for Supporting Internet Emergency Preparedness in IP Telephony RFC if it is determined that IP
    telephony requires special treatment above what would be in the requirements document. "
