Secure LTE-A access for critical public safety applications

拟议的项目涉及加强加拿大公共安全的技术。研究的目标是使用先进的无线网络和数据处理，以安全可靠的方式收集和处理信息，并根据需要部署可移动的网络和传感器，以监测感兴趣的区域，并以及时和可靠的方式向急救人员提供关键信息。这项研究直接关系到加拿大通用动力任务系统公司(GD-MS)以及制造和运营涉及公共安全应用的设备和网络的公司。该行业正在建设基于LTE宽带无线标准的700 MHz频段的全国性公共安全网络。LTE被广泛用于商业部署，但可以理解的是，公共安全网络在范围、覆盖、通话中断和安全方面有更严格的要求。拟议的工作将研究、分析和提供 中介网关(MG)的初始规范，可促进不同类型的传感器和“加固”的安全LTE接入节点之间的接口。传感器包括高分辨率视频、音频、跟踪系统和感知其他关键信息的设备。拟议的MG将弥合不同制造商设计的不同类型传感器的独特要求与LTE标准规定的特定格式和帧结构之间的差距。MG的设计将支持不同无线节点之间的快速部署和快速切换，同时保持数据的安全性和完整性。这项工作对GD-MS来说是重要和及时的，因为他们制造加固的可移动LTE节点，并且他们需要将他们的安全LTE网络与其他网络和设备接口。公共安全是全世界非常关注的问题，加拿大应该在采用加拿大大量先进技术方面发挥重要作用 以确保此类网络的稳健和可靠运行。拟议的工作直接旨在满足这一功能。

The proposed project addresses techniques to enhance public safety in Canada. The research targets the use of advanced wireless networking and data processing to collect and process information in a secure and reliable manner and to deploy transportable networking and sensors as needed to monitor areas of interest and deliver critical information to first responders in a timely and reliable ways. This research is of direct interest to General Dynamics Mission Systems Canada (GD-MS) as well as companies that manufacture and operate devices and networks involving public safety applications. The industry is in the process of building a nationwide public safety network in the 700 MHz band based on the LTE broadband wireless standard. LTE is widely deployed commercially, but understandably, public safety networks have more stringent requirements in terms of range, coverage, call drop-outs and security. The proposed work will study, analyze and provide initial specifications of a Mediation Gateway (MG) that facilitates the interface between different kinds of sensors and "hardened" secure LTE access nodes. The sensors include high resolution videos, audio, tracking systems and devices that sense other critical information. The proposed MG will bridge the gap between the unique requirements of different types of sensors designed by different manufacturers and the specific format and frame structures imposed by LTE standards. The MG will be designed to support fast deployment and rapid handoff among different wireless nodes while maintaining the security and integrity of data. This work is important and timely to GD-MS since they manufacture hardened transportable LTE nodes and they need to interface their secure LTE network with other networks and devices. Public safety is of great concern around the world, and Canada should play a major role in adapting the great array of Canadian advanced technologies to serve ensure robust and reliable operations of such networks. The proposed work aims directly at satisfying this function.
