Summary:After entering the 5G era, satellite-terrestrial in-tegrated network has become a hot issue of common concern, which combines the advantages of terrestrial communication and satellite communication to provide high-quality services for dense users. In this paper, we design a content distribution system model for multi-beam satellite-terrestrial cache-enabled network-s. Based on beam-hopping, we propose a greedy algorithm to achieve the goal of flexible and reasonable allocation of on-board resources including caching, power and bandwidth, according to the changing user demand preferences, thereby maximizing the system throughput by the multidimensional resource optimization. The simulation results show that the proposed resource allocation algorithm is superior to the traditional fixed power and bandwidth methods in terms of system throughput, and it also shows the outperformance of the most popular caching methods.
