摘要： 针对现有应急通信设备传输距离短、系统部署复杂、指挥调度设置在后方等问题，结合当前宽窄融合集群方案以及便携式应急通信设备，笔者提出一种应用于应急救援现场的便携式宽窄融合应急通信指挥系统。系统采用PDT+LTE解决方案，基于SIP的软交换技术实现宽带与窄带集群用户的统一管理、混合呼叫、多媒体集群调度等综合业务。结果表明：系统具有宽窄融合于一体、通信调度于一体、自备电源、便携式、即拉即用、免部署特点，覆盖范围为15～20 km。同时系统还可使用LTE专网基站+背负式Mesh拉远方案，扩大事故救援面积，保障救援通信，实现事故现场与前指、后指的二级分布式调度。

Abstract: In view of the short transmission distance of the existing emergency communication equipment, complex system deployment, and rear command and dispatch settings, this paper proposes a portable width and narrow fusion emergency communication command system applied to the emergency rescue site in combination with the current width and narrow fusion cluster scheme and portable emergency communication equipment. The system adopts PDT+LTE solution and soft switch technology based on SIP to realize the unified management of broadband and narrowband cluster users, mixed call, multimedia cluster scheduling and other integrated services. The results show that the system has the characteristics of integrating width and narrowness, integrating communication and dispatching, self-supplied power, portable, pull and use, free deployment, and covers an area of 15~20 km. At the same time, the system can also use the LTE private network base station plas the backpack-type Mesh remote scheme to expand the area of accident rescue, ensure rescue communication, and realize the two-level distributed scheduling between the accident site and the front command and rear command.
