摘要:

建设应急专网是为了满足重特大灾害事故救援、应急处突、重大活动保障等统一指挥调度通信的需要,是维护社会公共安全的重要通信手段。随着无线电技术的快速发展,传统的窄带应急通信技术体制难以满足新形势下多媒体数据通信、互联互通、安全抗干扰等需求,数字化、宽带化、泛在化成为应急专网发展的必然趋势。首先,概述了应急专网通信的技术体制及发展趋势,介绍了全球应急专网通信研究框架,重点分析了美国、欧洲、亚太等国家和地区应急专网频谱规划及使用现状,最后结合我国应急专网频谱规划情况,从技术趋势、产业发展、频段选择、建设模式等方面提出了我国应急专网建设的建议。

Abstract:

The construction of an emergency private network is the necessity of unified command and dispatch communications in rescue of disasters, emergency response, and major activity safeguard.It is an important communication means of public safety protection.With the rapid development of radio technology, the traditional narrowband emergency communication system is difficult to meet the needs of multimedia data, interconnection, anti-interference and other needs under the new situation.Digitization, broadband and ubiquity have become the inevitable trend of the development of emergency private networks.First of all, the technical system and development trend of emergency communication were summarized, the global emergency communication research framework were introduced, the frequency planning and current use status of the emergency private network in the United States, Europe, Asia-Pacific and other countries and regions were analyzed.Finally, combine with the current frequency planning, suggestions for the construction of China’s emergency private network from the aspects of technology trends, industrial development, frequency band selection, and construction mode were presented.

Key words: PPDR, frequency spectrum, emergency private network, broadband
