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.
The current 9-1-1 system was never intended to receive calls and data from these new and emerging technologies. As a result, 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.
The National Emergency Number Association identified this need for such an overhaul in 2000, published the Future Path Plan in 2001, and began development in 2003.
Why NG9-1-1 ?
The purposes of NG9-1-1 can be briefly described in four segments:
1. It fully replaces Enhanced 9-1-1 , with all capabilities and functions in place today.
We cannot drop features of E9-1-1 as we change over to a new base technology (IP) and entirely different, software-based and database control mechanisms. 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 .
2. It adds 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 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 call and message-generating services are introduced to the public.
3. It adds flexibility for the PSAPs and 9-1-1 authorities.
This flexibility ranges 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), to the 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.
4. It adds 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 acquire and pass data between all entities (with access controls). Inherent in this portion is support for disaster management and intercommunications with and between PSAPs, EOCs, DHS, and other emergency management entities.
