Research on service-driven network technologies for space-air-ground-sea integration
Facing the emerging novel applications and service demands,space-air-ground-sea integrated network of-fers advantages such as global coverage,high efficiency,flexibility,elasticity,and reliability.It provides intelligent,collaborative,and efficient ubiquitous information services for diverse service scenarios in many fields,and is an im-portant part of future mobile communication system.Firstly,the domestic and international development status,net-work architecture,demands,and challenges of space-air-ground-sea integration were analyzed.Then,driven by the de-mand for carrying massive diverse services,key network technologies,including network slicing,mobile edge com-puting,and communication-sensing-computing integration,were investigated.Finally,the future development direc-tion of space-air-ground-sea integration was discussed from the perspectives of intelligence,integration,and security.
