Abstract
A method for prediction of UT handovers in a satellite communications network is provided. Optimal characteristics regarding the beams of satellites and regarding a one UT are determined. For each of a plurality of the satellite beams, for each of a plurality of instants of time tn, an estimated signal strength as seen at the UT is determined, wherein each estimated signal strength is determined based on the optimal at the respective time tn. A next instant of time tm is determined at which the estimated signal strength for a candidate beam that is within the view of the UT is greater than or equal to the estimated signal strength for the satellite beam that is currently servicing the UT. A handover of the UT, at the time tm, from the satellite beam that is currently servicing the one UT to the candidate beam is determined.
