Abstract

Abstract

A non-sufficiently guaranteed handover scheme for multiple services is proposed in this paper. Under this scheme, the channels will be allocated and reserved for the arriving calls to be served when an interval is less than the maximum cell residence time. And when the calls are terminated, the allocation strategy will be adjusted for those associated channels facing the risk of handover failure. At the mean time, the degree of non-sufficient guarantee is adjusted periodically according to real-time performance of the handover calls. Through simulation, the QoSs of the proposed strategy are analyzed under different degrees of non-sufficient guarantee, and the efficiency for multiple services is thus verified. The simulation results show that, the proposed channel allocation strategy (IGH) can significantly reduce the new call blocking probability, at the expense of slight handover failure probability. Therefore, compared with the guaranteed handover scheme, IGH is more suitable for multi-service LEO constellation communication system.
