论文摘要

在无线蜂窝通信网络的背景下,Handover(HO)管理吸引了研究的关注。 HO管理的一个关键问题是处理移动用户经历的HOS的增加。为了解决这个问题,近年来已经研究了HO跳过技术。在本文中,我们提出了一种新颖的HO跳过计划,即基于时间的HO跳过。在拟议的方案中,用户的HOS由一定固定的时间控制,我们称之为跳过时间。跳过时间可以作为系统参数进行管理,从而可以灵活地跳过操作。我们根据随机几何方法分析了提议方案的传输性能。在用户执行基于时间的HO跳过的情况下,我们得出了两个性能指标的分析表达式:HO速率和预期数据速率。分析结果表明,基于时间的HO跳过的场景超出了场景而不会跳过HO,尤其是当用户快速移动时。此外,我们透露,有一个独特的最佳跳过时间,使传输性能最大化,我们大约获得了传输性能。

Handover (HO) management has attracted attention of research in the context of wireless cellular communication networks. One crucial problem of HO management is to deal with increasing HOs experienced by a mobile user. To address this problem, HO skipping techniques have been studied in recent years. In this paper, we propose a novel HO skipping scheme, namely, time-based HO skipping. In the proposed scheme, HOs of a user are controlled by a certain fixed period of time, which we call skipping time. The skipping time can be managed as a system parameter, thereby enabling flexible operation of HO skipping. We analyze the transmission performance of the proposed scheme on the basis of a stochastic geometry approach. In the scenario where a user performs the time-based HO skipping, we derive the analytical expressions for two performance metrics: the HO rate and the expected data rate. The analysis results demonstrate that the scenario with the time-based HO skipping outperforms the scenario without HO skipping particularly when the user moves fast. Furthermore, we reveal that there is a unique optimal skipping time maximizing the transmission performance, which we obtain approximately.
