Next Generation 9-1-1
Next Generation 9-1-1 (abbreviated NG9-1-1) refers to an initiative aimed at updating the 9-1-1 service infrastructure in the United States and Canada to improve public emergency communications services in a growingly wireless mobile society. In addition to calling 9-1-1 from a phone, it intends to enable the public to transmit text, images, video and data to the 9-1-1 center (referred to as a Public Safety Answering Point, or PSAP). The initiative also envisions additional types of emergency communications and data transfer.〔(U.S. Dept. Of Transportation NG9-1-1 initiative )〕 This NG9-1-1 infrastructure is intended to replace the current services over time. The National Emergency Number Association (NENA) first identified the need for NG9-1-1 in 2000, and started development actions in 2003, and is nearing full definition and standards for NG9-1-1. Since 2006, the US Department of Transportation (DOT) in the United States and the Canadian Radio-television and Telecommunications Commission (CRTC) in Canada have been leading their respective initiatives, which include research and development projects aimed at advancing NG9-1-1.〔(''Mission Critical Magazine'': "Greater Expectations" )〕〔("T9-1-1 CRTC INTERCONNECTION STEERING COMMITTEE REPORT" )〕 On January 24, 2013, the CRTC announced the first step toward a Canadian implementation of NG9-1-1.〔("CRTC announces enhancements to 911 services for Canadians with hearing or speech impairments" )〕 Several US states have implemented versions of NG9-1-1, as of October 2013.
==Purpose and history==
Planning for NG9-1-1 started in 2000 and was published in NENA's Future Path Plan in 2001.〔(NENA NG9-1-1 Future Path Plan )〕 NENA's NG9-1-1 Project began in 2003 and continues to an ultimate goal of establishing national NG9-1-1 architecture and operations standards, and implementation plans to accomplish advanced 9-1-1 systems and services. Public safety communications experts recognized that the nation's current 9-1-1 system was not capable of handling the text, data, images and video that are increasingly common in personal communications. The stated goal of a related USDOT project is: "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, and allow the emergency services community to take advantage of advanced call delivery and other functions through new internetworking technologies based on open standards."〔(NG9-1-1 Initiative Overview )〕
The project is aimed at supporting establishment of a national architecture for an NG9-1-1 system that would meet these goals, and to create a transition plan for NG9-1-1.
The "Proof of Concept" phase of the DOT project, using the architecture designed by NENA, was completed in 2008, and a report was issued on the results of a proof of concept demonstration conducted over the course of that year.〔(NG9-1-1 Proof Of Concept Test Report )〕 That report has served as a basic blueprint for planning and implementation of these capabilities. Actual implementation of these capabilities is expected to take several years, and will require changes to existing communications infrastructure, as well as changes to the way PSAPs operate.〔(DOT NG9-1-1 Overview )〕
