Network sub-domain management and control method and device for low earth orbit satellites

The invention provides a network sub-domain management and control method and device for a low earth orbit satellite, and relates to the technical field of satellite networks. The method comprises the steps that a geographic area where a ground user is located is divided into a plurality of geographic sub-areas according to service attribute parameters of the ground user and the maximum service handling capacity of low-orbit satellites, a control sub-area corresponding to a first geographic sub-area in the multiple geographic sub-areas is determined, and the control sub-area comprises a plurality of first low-orbit satellites; according to the position information and the movement speed of the plurality of first low-earth-orbit satellites, predicting the time when the plurality of first low-earth-orbit satellites serve the first geographic subarea; and determining the first low-orbit satellite serving the first geographic sub-region for the longest time as a controller satellite of the first geographic sub-re
