What is NG 9-1-1?
The evolution of emergency calling beyond the traditional voice 9‐1‐1 call has caused the
recognition that our current E9‐1‐1 system is no longer able to support the needs of the future.
Next Generation 9‐1‐1 (NG9‐1‐1) networks replace the existing narrowband, circuit switched 9‐1‐1 networks which carry only voice and very limited data. Currently there are difficulties in supporting such things as text messages for emergencies, images and video (including support
for American Sign Language users), and easy access to additional data such as telematics data,
building plans and medical information over a common data network.
In addition, the need for inter‐communications across states, between states, and across international boundaries requires that we create a more flexible 9‐1‐1 system design with much greater data handling capabilities. A highly standardized system is essential and critical to seamlessly support communications and data transfer across county, state, and international borders, and across
the multitude of emergency response professions and agencies, from traditional PSAPs to
Poison Control Centers, trauma centers, Coast Guard, and disaster management centers.
There will be numerous and varied steps toward the new system named NG9‐1‐1, and vendors are already referring to their products as aimed at, enabling, or being wholly NG9‐1‐1 compliant. Vendors who have direct experience with parts of today’s E9‐1‐1 system and service, and who are directly involved in NENA and other standards development can and are starting to produce NG9‐1‐1 oriented products.
The direction of the Standards that will support NG9‐1‐1 is becoming clear, and demonstrations and trials are beginning to appear and will contribute to continued standards development. Despite this progress, a fully featured, truly “standards based” NG9‐1‐1 system is not yet identifiable, because the necessary standards are still in development. As a result, a summary definition of NG9‐1‐1 as a system and service process is needed to clarify what is involved.
Why NG 9-1-1?
Fully replace Enhanced 9‐1‐1, with all capabilities and functions in place today
Add capabilities to support changes for current and new types of Originating Service
Providers
Add flexibility for the PSAPs and 9‐1‐1 Authorities
Add capabilities to integrate and interoperate with emergency entities beyond the PSAP
