A QoE Driven Cross-Domain Management Architecture for Space-Air-Ground Integrated Network

With the increasing demands for networks, space-air-ground integrated network (SAGIN) and quality of experience (QoE) have been proposed in recent years. In order to adapt to the more complex network environment in the future, the network management based on QoE in SAGIN comes into being. In this paper, we propose a QoE driven cross-domain management architecture for SAGIN. From the perspective of systematicity, we focus on the process of the network management, including the required network functions, the distribution of different functions and the network operation strategy. Therefore, we divide the network architecture into subsystems, functional modules and network facilities, and propose the corresponding network operation strategies. In addition, we propose a network task allocation strategy based on Q-learning and apply it to the simulation environment of proposed architecture. Through simulation experiment, we demonstrate the advantages of QoE in SAGIN.
