Collaborative Research: CRI: IAD: A Testbed for Research and Development of Next Generation 9-1-1 Services

传统的911系统可以追溯到20世纪70年代，只支持语音，而非紧急通信现在采用其他媒体。为911增加额外的媒体带来了机遇和挑战。短信、手机拍摄的图像、视频剪辑和自动故障通知消息可以通过加快紧急响应和缩短故障清除时间来显著增强911服务。住宅、游牧和移动VoIP使用的快速增长要求开发基于VoIP的下一代9-1-1系统和服务，以取代目前的电路交换9-1-1系统。除了媒体和移动性支持方面的限制外，现有系统效率低下，无法轻松适应新功能。该项目是北德克萨斯大学、哥伦比亚大学和德克萨斯农工大学之间的合作项目，UNT将作为牵头机构，开发一个测试平台，用于研究下一代911服务的理解和分析。该试验台使可靠性、安全性、功能适当的隐私和其他在大规模VoIP中已经困难的领域的研究和开发成为可能，但当VoIP系统是关键基础设施时，这些领域就变得令人望而生畏。这个项目的广泛影响是多方面的。在州和联邦政府都在规划下一代应急通信平台的过程中，一个基于互联网的911研究测试平台尤为重要，不幸的是，这些平台往往没有充分的与供应商无关的测试和评估。测试平台的用户将调查与定位9-1-1呼叫者相关的问题，确保公共安全应答点，确保大规模紧急情况下9-1-1服务的持续可用性，预测紧急情况，提供公民警报（“反向9-1-1”），以及改善机构间协调。pi希望将该基础设施的研究成果转化为工程指南，并在政府组织、IETF和国家紧急号码协会（NENA）等标准机构以及911中心之间传播结果。此外，这个项目的实验结果将对美国各地的居民有用。

Traditional 9-1-1 systems, which date back to 1970s, support only voice, while non-emergency communications now feature other media. Adding additional media for 9-1-1 presents opportunities and challenges. Text messages, images captured by cell phones, video clips, and automatic crash notification messages can dramatically enhance the 9-1-1 services by expediting emergency responses and reducing crash clearance times. The rapid increase of residential, nomadic and mobile VoIP usage requires the development of VoIP-based next generation 9-1-1 systems and services that will replace the current circuit-switched 9-1-1 systems. Beyond limitations in media and mobility support, existing systems are inefficient and cannot easily accommodate new functionality. This project is a collaboration among University of North Texas, Columbia University and Texas A&M University, where UNT will be the lead institution, to develop a testbed that will enable research on understanding and analysis of next generation 9-1-1 services. The testbed make possible research and development in reliability, security, function-appropriate privacy and other areas that already difficult in large scale VoIP, but which become daunting when the VoIP system is critical infrastructure. The broader impacts of this project are many. A testbed for Internet-based 9-1-1 research is particularly important as both state and federal governments are in the process of planning next-generation emergency communication platforms, unfortunately often without adequate vendor-neutral testing and evaluation. Users of the testbed will investigate issues related to locating9-1-1 callers, securing Public Safety Answering Points, ensuring continuous availability of 9-1-1 services during large-scale emergencies, predicting emergencies, providing citizen alerts ("reverse 9-1-1"), and improving inter-agency coordination. The PIs expect to translate results from research on this infrastructure to engineering guidelines and disseminate results across government organizations, standards bodies such as IETF and National Emergency Number Association (NENA) and 9-1-1 centers. Moreover, the findings from the experiments in this project will be useful for the residents across USA.
