Abstract: As an important part of the space-integrated-ground information networks, the low-earth-orbit satellite communication system has attracted more and more attention due to its advantages of low delay and low cost. According to the characteristics of low-earth-orbit satellites and the diversity as well as uneven distribution of users’ services, the corresponding resource scheduling methods have also been widely studied. Firstly, summarizes the data-driven and knowledge-driven methods and analyzes their characteristics respectively, including the introduction of data-driven methods and knowledge-driven methods, the definition and classification of knowledge and the ways of knowledge integration. Secondly, the traditional mathematical model-driven resource scheduling method is introduced, and then the data-driven resource scheduling method and the data-knowledge-driven resource scheduling method are emphatically introduced. Finally, the challenges of resource scheduling for low-earth-orbit satellites in the future are summarized and prospected.
