摘要

提出一种适用于LEO(低轨道)星座通信系统的信道分配方案。该方案为切换呼叫提供了保留信道

降低了切换呼叫的阻塞概率。同时

采取新呼叫排队策略抑制保留信道引起的新呼叫阻塞概率的恶化

如果正在进行的呼叫离开

队列中的新呼叫可以按照次序获得分配信道。结果表明

该方案可以显著降低切换呼叫阻塞概率

并使新呼叫阻塞概率得到改善。

Abstract

A channel assigning scheme which was adapted to LEO constellation communication system was proposed. The scheme provided reserved channel for handover call to reduce blocking probability of handoff call.Meanwhile

new call queuing strategy was adopted to restrain new call balockage deterioration caused by reserving scheme. When there was a departure of ongoing call

new call in queue could obtain channel assigning priority-ranked. It is shown that the scheme can reduce the handoff call blocking probability observably

and new call blocking probability is improved at the same time.
