摘　　要：通信覆盖的空间域具有多元性,导致应急状态下的通信速率难以达到保障,为此提出基于区块链的多域协同空间应急通信网络技术。借助数据流切割技术对通信数据流细粒度的划分能力,利用其根据通信的覆盖范围、通信容量以及用户分布,实现空间域的灵活划分和动态调整;建立不同时空域之间的通信关联关系,在应急通信阶段,根据链路与业务的匹配度,执行具体的信息传输。在测试结果中,应急通信场景中用户移动性对于数据传输速率的影响基本可以忽略不计,且具体的数据传输速率始终稳定在555.0 Mbps以上。Due to the diversity of communication coverage space,it is difficult to guarantee the communication rate in emergency.Therefore,a multi-domain collaborative space emergency communication network technology based on blockchain is proposed.With the help of data stream cutting technology,the fine-grained division ability of communication data stream can be used to realize flexible division and dynamic adjustment of spatial domain according to communication coverage,communication capacity and user distribution.Establish the communication relationship between different airspace,and in the emergency communication stage,according to the matching degree of link and service,carry out specific information transmission.In the test results,the influence of user mobility on the data transmission rate in emergency communication scenarios is basically negligible,and the specific data transmission rate is always stable above 555.0 Mbps.
