Research on the Integrated Space-Air-Ground Communication Network Based on Network Slicing and its Key Technologies

In recent years, with the power network continuously developed and constructed, various new types of services are constantly emerging. Diversified business needs and the surge data of users and terminal devices pose new challenges to the current architecture of power communication network. Thus, the network need to be upgraded by using related technologies to meet the requirements of the so-called Energy Internet's development. Network slicing technology can build multiple logical networks with differentiated performance on the same physical infrastructure according to different service requirements. The personalized customization and security isolation brought by network slicing can better meet the needs of service requirements while saving network construction costs. The Integrated Space-Air-Ground (SAG) Communication Network can achieve a ubiquitous network coverage and be applied in emergency communication scenario. Therefore, network slicing technology can be introduced to the wireless communication part of the Integrated SAG network to solve the problems faced by current power communication network. This paper first introduces the concept and advantages of network slicing technology and analyzes current state of the power communication network, then proposes an Integrated SAG Network architecture based on network slicing and finally discusses its key technologies.
