极端条件下应急通信系统关键技术
Key technologies for emergency communication systems under extreme conditions
摘要
Abstract
Aiming at the existing problems and technical blind spots of the emergency communication system under extreme conditions such as disconnection of roads,power supply and network,we carried out research on the key technologies of the emergency communication system and the design of the sys-tem architecture.Firstly,by analyzing the reasons for disconnection of road,power and network after a disaster,three major demand characteristics of the emergency communication system under extreme conditions were obtained;secondly,three key technologies,namely,reliability enhancement,flexible ad-aptation and rapid deployment of the communication system,were explored,and the business types,ap-plicable scenarios and performance characteristics of various technologies,such as space-air-tandem network slicing and network cooperation technology,were analyzed,and a centralized and redundant e-mergency communication system based on the main framework of"space-air-ground"and supported by"public-specialized combination and wide-narrow fusion"was established,and a multi-level resource cooperative management scheme covering the terminal layer,access layer,network layer and decision-making layer was proposed.The results show that the emergency communication system can realize full coverage of communication network,real-time transmission and analysis of multi-source information,and resource sharing at all levels under extreme conditions,thus improving the emergency communica-tion guarantee capability and rapid recovery capability.The research can provide a reliable solution to the problem of recovery and guarantee of emergency communication under extreme conditions.关键词
