"The Next Generation 9-1-1 (NG9-1-1) Initiative is a research and development project funded by the US Department of Transportation (USDOT) to define the framework and plan to deploy Internet Protocol (IP)-based emergency communications across the nation. The project has helped to define the concept of operations, functional requirements, and system architecture, and to develop a transition plan that considers implementation costs, values, and risks. From a technical perspective, the project has been guided by its long-term goal: 'To enable the general public to make a 9-1-1 'call' (any real-time communication--voice, text, or video) from any wired, wireless, or IP-based device...' Additional important considerations included advancing call delivery, locating callers, and improving system functionality 'through new internetworking technologies based on open standards.' The NG9-1-1 Initiative has helped demonstrate these principles throughout the project's duration. The NG9-1-1 Final System Design document is the culmination of the technical work of the NG9-1-1 Initiative. Starting with the NG9-1-1 Concept of Operations (CONOPS), the project team leveraged past work done in the public safety and standards communities. After the CONOPS, the project developed both high-level and detailed requirements, an architecture analysis report, and the initial system design. These project artifacts served as the basis for the Proof of Concept (POC) Deployment Plan."
