1. An offloading method, of a satellite-to-ground edge computing task, assisted by a satellite and a high-altitude platform, wherein comprising the following steps:
step A: acquiring, by a low earth-orbit satellite (LEO SAT), a related information in a system;
step B: selecting, by the LEO SAT according to an acquired related information, a proper high-altitude platform for a ground user to associate with according to a method for associating the ground user with the high-altitude platform;
step C: offloading a computing task to an associated platform according to an association result between the ground user and the high-altitude platform by using a multi-input and multi-output (MIMO) transmission method;
step D: dividing, by the high-altitude platform according to a result of a computing task allocation method after receiving the computing task of the ground user, the computing task of the ground user into two parts, that is, a task processed by the high-altitude platform and a task offloaded to the LEO SAT for processing; for the task processed by the high-altitude platform, allocating, by the high-altitude platform, a proper computing resource according to a computing resource allocation method to process the computing task of the ground user; and for the computing task offloaded to the LEO SAT, offloading, by the high-altitude platform, the computing task to the LEO SAT by using the MIMO transmission method; and
step E: allocating, by the LEO SAT after receiving a task offloaded by the high-altitude platform, a computing resource to each of the computing task according to the computing resource allocation method, to complete the computing task.
