US 2022/0069902 A1 · HANDOVER CONTROL METHOD AND DEVICE

Abstract

The present disclosure relates to the field of wireless communication technology, and in particular, to a handover control method and device. The existing handover mechanism may cause the problem that too frequent handover measurement of a terminal increases the energy consumption of the terminal, negatively impacting the power saving of the terminal. A source satellite base station of the embodiments of the present disclosure receives auxiliary information reported by a terminal, determines at least one candidate satellite base station according to satellite base station orbital map information of the current region and the auxiliary information, and returns a handover command to the terminal according to the at least one candidate satellite base station, so that the terminal determines, according to the handover command, a target satellite base station to which the terminal is to be handed over, and is handed over from the source satellite base station to the target satellite base station. As the embodiments of the present disclosure provide a handover procedure for source satellite base station decision triggering, a terminal does not need to frequently measure the current serving base station and an adjacent base station, thereby simplifying the handover procedure and reducing the energy consumption of the terminal.

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, at least one candidate satellite base station according to orbital map information of satellite base stations in a current region where the source satellite base station is located and the auxiliary information;
returning, by the source satellite base station, a handover command to the terminal according to the at least one candidate satellite base station, 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.

A handover control method, comprising:

reporting, by a terminal, auxiliary information to a source satellite base station currently accessed, to allow the source satellite base station to determine at least one candidate satellite base station according to orbital map information of satellite base stations in a current region where the source satellite base station is located and the auxiliary information;
determining, by the terminal, a target satellite base station to be switched to according to a handover command returned by the source satellite base station, and switching from the source satellite base station to the target satellite base station.

A source satellite base station comprising a processor, a memory and a transceiver,

wherein the processor is configured to read programs in the memory to perform:
