Abstract
A feeder link handover method, device and apparatus, and a handover method, device and apparatus for user equipment belonging to a satellite are provided. The method includes: interacting with a target gateway by a source gateway and determining a handover time instant T and/or a target cell activation time instant T′, wherein the handover time instant T is a time instant at which a previous feeder link is disconnected and establishment of a new feeder link is initiated, the target cell activation time instant T′ is T+a time period Δ (delta) required for the establishment of the new feeder link; initiating a feeder-link handover at the handover time instant T, and instructing a user equipment to synchronize with a target cell at the T′.
