| Abstract(in English) | In Low Earth-Orbital Satellite(LEOS)mobile communication systems, one of the most important technical issues is handover between cells formed by spot-beams of a satellite. In this study, we consider a hierarchical channel structure to improve handover performance of a LEOS system. In order to measure the Quality of Service, the probability of the rejection of a newly arrived call and the forced termination due to the failure of a handover are derived. Using this performance measures, we discuss the sysytem performance. As the result, it is shown that the performance can be improved by the hierachical channel strucure with the global handover channels and the number of channels of each group has the opdtimum ratio. |
