NG9-1-1 Project

In the past 15 years, advancements in modern communications technology have created the need for a more advanced system to access emergency care. While the existing 9-1-1 system has been a success story for more than 30 years, it has been stretched to its limit as technology advances.

New wireless and IP-based communications devices are being developed at a rapid rate, offering capabilities such as text and video messaging. Unfortunately, the current 9-1-1 system was never intended to receive calls and data from these new and emerging technologies.
As a result, through cumbersome adaptations, E9-1-1 is being asked to perform functions it was not designed to handle. In short, the nation’s 9-1-1 systems are in need of a significant overhaul.
NENA identified this need in 2000, published the Future Path Plan in 2001, and began development activities toward this end in 2003.

Project Results and Status

Currently, we are expecting that most NENA Requirements, Standards and Information documents for NG9-1-1 will be completed in 2011. Specific results, both current and pending, are available at the Overall NG9-1-1 Status page.

Why NG9-1-1 ?

 The purposes of NG9-1-1 can be briefly described in four segments:

  1. Fully replace Enhanced 9-1-1, with all capabilities and functions in place today

We cannot accidentally drop even detailed standard features of E9-1-1 as we change over to a new base technology (IP) and entirely different software based and database control mechanisms to perform 9-1-1 system capabilities and features, for both callers and PSAPs.  This applies right down to seldom used but critical features for dealing automatically with real time call routing and delivery problems, or troubleshooting of call and data issues.  All current originating service types must continue to be supported seamlessly, with no service dropout during the transition from E9-1-1 to NG9-1-1.

  1. Add capabilities to support changes for current and new types of Originating Service Providers

E9-1-1 supports voice calling for wireline, cellular, and VoIP service providers today.  There are current and certainly future needs for different and new calling technologies, including non-voice messaging of various types, devices generating data-only messages (such as sensors), photo and video transmission, and unknown future services.  A primary objective is to establish a common, IP based interface that developers can design to as they develop new services, so that 9-1-1 can be planned for and then connected to quickly as 9-1-1 call and message generating services are introduced to the public.

  1. Add flexibility for the PSAPs and 9-1-1 Authorities

These range from the ability to transfer calls, messages, and data between any PSAPs on any interconnected NG9-1-1 system anywhere in the country (and beyond), ability to directly activate alternate routing much more quickly, to controlling data flow.  The PSAP will be able to access a wide range of supportive databases and share new and more robust forms of data to facilitate call processing, emergency response and comprehensive incident management.  Basic tools to support disaster related 9-1-1 call control and to handle non-voice call types are also involved.

  1. Add capabilities to integrate and interoperate with emergency entities beyond the PSAP

Other emergency and public safety related entities will be able to interconnect to the NG9-1-1 network and system, and be able to receive calls and data sent by the NG9-1-1 system or PSAPs, as well as (with access controls) acquire and pass data between all entities.  Inherent in this portion is support for disaster management and intercommunications with and between PSAPs, EOCs, DHS, and other emergency management entities.

All of the above four areas of system development also require that many policy, educational and operations issues be treated as part of the overall Project prior to implementation.  The addition of capabilities beyond those of today’s E9-1-1 systems, for instance, drive needs in these areas that are not easily derived from past practice or experience. 

System and procedural tools are required to support 9-1-1 Authorities and PSAPs, and to deal with additional data sources, different types of calling technologies and changes in call processing times at the PSAP, and new features that require new procedures. A variety of educational products are required to allow understanding, and support preparation, smooth transition and ongoing operation of NG9-1-1. 

Guidelines and recommendations for the transition of stakeholders to NG9-1-1 are critical.  All of these aspects are represented and, as additional perspectives occur, periodically updated in the development activities in the NG9-1-1 Project plan.

Next Generation 9-1-1(?) Summary Description

A system comprised of Emergency Services IP networks (ESInets), IP-based Software Services and Applications, Databases and Data Management processes that are interconnected to Public Safety Answering Point premise equipment.  The system provides location-based routing to the appropriate emergency entity.  The system uses additionally available data elements and business policies to augment PSAP routing. The system delivers geodetic and/or civic location information and the call back number.

The system supports the transfer of calls to other NG9-1-1 capable PSAPs or other authorized entities based on and including accumulated data.  NG9-1-1 provides standardized interfaces for call and message services, processes all types of emergency calls including non-voice (multi-media) messages, acquires and integrates additional data useful to call routing and handling for appropriate emergency entities. NG9-1-1 supports all E9-1-1 features and functions and meets current and emerging needs for emergency communication from caller to Public Safety entities.

For a more detailed and potentially more up to date description of NG9-1-1 see “What is NG9-1-1?”  This document covers structure and components of NG9-1-1 and the overall roles that NENA plays in the development of NG9-1-1.  All questions and comments should be addressed to Roger Hixson, NENA Technical Issues Director.
