A handover control method, comprising: receiving, by a source satellite base station, auxiliary information reported by a terminal; determining, by the source satellite base station, a motion state of the terminal according to the auxiliary information, determining, by the source satellite base station, at least one candidate satellite base station according to the motion state of the terminal, the orbital map information of satellite base stations in the current region and the auxiliary information, characterized by comprising: sending, by the source satellite base station, a handover request message to at least one candidate satellite base station through an inter-satellite interface between the satellite base stations, receiving, by the source satellite base station, a handover confirmation message returned by a candidate satellite base station; wherein the handover confirmation message is sent after the candidate satellite base station confirms being capable of accepting the handover request message according to load of the candidate satellite base station or a preset constraint; taking, by the source satellite base station, one or more candidate satellite base stations which return handover confirmation messages as candidate target satellite base stations according to a local strategy; returning, by the source satellite base station, a handover command containing the at least one candidate target satellite base station to the terminal, to allow the terminal to determine a target satellite base station to be switched to according to the handover command and switches from the source satellite base station to the target satellite base station. receiving, by a source satellite base station, auxiliary information reported by a terminal; determining, by the source satellite base station, a motion state of the terminal according to the auxiliary information, determining, by the source satellite base station, at least one candidate satellite base station according to the motion state of the terminal, the orbital map information of satellite base stations in the current region and the auxiliary information, characterized by comprising: sending, by the source satellite base station, a handover request message to at least one candidate satellite base station through an inter-satellite interface between the satellite base stations, receiving, by the source satellite base station, a handover confirmation message returned by a candidate satellite base station; wherein the handover confirmation message is sent after the candidate satellite base station confirms being capable of accepting the handover request message according to load of the candidate satellite base station or a preset constraint; taking, by the source satellite base station, one or more candidate satellite base stations which return handover confirmation messages as candidate target satellite base stations according to a local strategy; returning, by the source satellite base station, a handover command containing the at least one candidate target satellite base station to the terminal, to allow the terminal to determine a target satellite base station to be switched to according to the handover command and switches from the source satellite base station to the target satellite base station. sending, by the source satellite base station, a handover request message to at least one candidate satellite base station through an inter-satellite interface between the satellite base stations, receiving, by the source satellite base station, a handover confirmation message returned by a candidate satellite base station; wherein the handover confirmation message is sent after the candidate satellite base station confirms being capable of accepting the handover request message according to load of the candidate satellite base station or a preset constraint; taking, by the source satellite base station, one or more candidate satellite base stations which return handover confirmation messages as candidate target satellite base stations according to a local strategy; returning, by the source satellite base station, a handover command containing the at least one candidate target satellite base station to the terminal, to allow the terminal to determine a target satellite base station to be switched to according to the handover command and switches from the source satellite base station to the target satellite base station.
