Thinking about the integrated communication of air, space and earth based on the "7.20 Zhengzhou rainstorm"

【 pick   want 】 in the light of “7·20 Zhengzhou torrential rain ” The new emergency rescue method in the incident is summarized and thought , This paper explores the development idea and scheme of the space earth integrated communication network for emergency communication , And give some suggestions . In the “7·20 Zhengzhou torrential rain ” In emergency communication rescue , The ground operators deployed unmanned aerial vehicles to realize the communication recovery of local areas , With the help of satellite communication, provide voice and short message services for the communication blocked areas . As an indispensable part of the integrated communication network of space and space , UAV and satellite communication have become a new and effective emergency communication mode in this rescue . In order to better enhance the ability to respond to emergencies , In the construction of space and space integrated communication network , We should gradually establish a unified technical system , Realize the business in stages 、 Heterogeneous network integration of system and system .

stay 5G In the research process of mobile communication ,3GPP、ITU And other organizations clearly put forward the need to build an integrated space and earth communication network . As the future development direction of communication system, the space earth integrated communication network , People pay more and more attention to it , Compared with terrestrial communication network , The space earth integrated communication network can break through the limitations of terrain and surface , Extend the communication link to space 、 In the air 、 land 、 Natural space such as the ocean , Achieve global ubiquitous access and connection [1-2].

stay “7·20 Zhengzhou torrential rain ” Emergency communication rescue , Operators have adopted the methods of satellite emergency communication and mobile air platform emergency communication to provide emergency communication support services for areas where communication is interrupted , It effectively ensures the safety of people's lives and property and social operation . this “7·20 Zhengzhou torrential rain ” The emergence of a new emergency communication mode in the rescue also marks the gradual development of the air space integrated communication network . With the integration of space and earth communication network in emergency communication 、 military 、 The political and economic fields are playing an increasingly important role , The integrated communication network of space and space has been highly concerned and developed by countries all over the world .
