1. A method for operating a satellite communication system, comprising:
interconnecting a first controller of a first satellite constellation and a second controller of a second satellite constellation in the satellite communication system to form an interconnected constellation, wherein the second satellite constellation is different from the first satellite constellation, and the interconnected constellation comprises the first satellite constellation and the second satellite constellation;
utilizing the first controller to obtain first control information on the first satellite constellation, and receive second control information on the second satellite constellation from the second controller, wherein the first control information indicates a link quality of a first communication link between a user terminal and a first satellite of the first satellite constellation, and the second control information indicates a link quality of a second communication link between the user terminal and a second satellite of the second satellite constellation; and
performing data communication via the interconnected constellation without using an intersatellite link, according to the first control information and the second control information, comprising:
when the link quality of the second communication link is higher than the link quality of the first communication link, utilizing the first controller to select the second satellite as a candidate satellite for data transmission between the user terminal and a gateway.
