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

传统的9-1-1系统可以追溯到20世纪70年代，它只支持语音，而非紧急通信现在以其他媒体为特色。为9-1-1增加额外的媒体带来了机遇和挑战。短信、手机拍摄的图像、视频剪辑和自动坠机通知消息可以通过加快应急响应和减少坠机清理时间来显著增强9-1-1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，以取代当前的电路交换9-1-1系统。除了媒体和移动支持方面的限制外，现有系统效率低下，无法轻松适应新功能。该项目是北得克萨斯大学、哥伦比亚大学和德克萨斯农工大学之间的合作，UNT将是该大学的牵头机构，以开发一个试验台，使研究能够理解和分析下一代9-1-1服务。试验台使在可靠性、安全性、适合功能的隐私和其他领域的研究和开发成为可能，这些领域在大规模VoIP中已经很困难，但当VoIP系统成为关键基础设施时，这些领域变得令人望而生畏。这个项目的更广泛影响是多方面的。基于互联网的9-1-1研究试验台尤其重要，因为州政府和联邦政府都在规划下一代紧急通信平台，不幸的是，往往没有足够的供应商中立的测试和评估。试验床的用户将调查与定位9-1-1呼叫者、保护公共安全应答点、确保在大规模紧急情况下持续提供9-1-1服务、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有关的问题。PIS希望将这一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)等标准机构和9-1-1中心之间传播结果。此外，该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.
