Problems solved by technology
Most of the existing inter-star switching is for a single attribute, and the effect of switching can only achieve the optimum of one attribute at the expense of other attributes, so the method of switching with a single attribute will also be affected by the poor quality of other attributes. cause switching failure

The invention belongs to the field of low-orbit satellite communication, and in particular relates to a method for controlling switching of low-orbit satellite communication lines based on a multi-objective genetic algorithm. information, and predict the start time and switching time of a single coverage satellite-to-terminal communication connection; according to the start time and switching time of a single coverage satellite-to-terminal communication connection, a directed graph of the switching relationship between a terminal and a satellite is obtained; Pareto multi-objective The genetic algorithm screens the switching paths in the directed graph of the switching relationship between the terminal and the satellite to find the optimal switching path; controls the switching between the low-orbit satellite and the terminal according to the optimal switching path; the present invention combines prediction with multiple attributes to predict Finding a high-speed terminal handover route with better satellite multi-attributes within a period of time can effectively improve the success rate of handover, reduce the time of handover, and increase the effectiveness of handover.
Description
Switching control method of low-orbit satellite communication line based on multi-objective genetic algorithm technical field The invention belongs to the low-orbit satellite communication field, be specifically related to a kind of low-orbit satellite communication based on multi-object genetic algorithm Communication line switching control method. Background technique [0002] In the near future, mobile communication networks are personalized and diversified seamless communication networks that support cross-standard and cross-protocol connections. It can break through the limitations of space, time and bandwidth on network equipment, and fully integrate data, voice, multimedia and other services. to communicate with anyone, anytime, anywhere and in any way. The current communication network is based on the terrestrial cellular mobile network. Mainly, wireless local area network as a supplementary communication system can basically meet the needs of most users, but ...
