Abstract

Abstract:

By analyzed the scenario characteristics of 6G integrated satellite and terrestrial network, the current state of research on edge computing capabilities on satellite, and the demand of cloud-edge collaboration, a network architecture that combines computing power network technology to achieve cloud-edge collaboration for integrated satellite and terrestrial networks was proposed, and global resource awareness and collaborative policy scheduling for integrated satellite and terrestrial networks by introducing a network function cloud-edge collaboration function was achieved .Based on this architecture, a unified resource management mechanism of the integrated satellite and terrestrial network was proposed, included a global resource awareness technology that could managed the computing and network resources of the integrated satellite and terrestrial network, and a policy generation technology that could collaborate with the computational capabilities of the cloud-edge and the integrated satellite and terrestrial network.Finally, the rationality of the cloud-edge collaborative architecture proposed in this article, as well as the correctness of resource awareness technology and policy scheduling technology, were verified through a self-developed mobile communication network platform.

Key words: integrated satellite and terrestrial network, network architecture, mobile edge computing, cloud-edge collaboration mechanism, computing power network, resource management
