当今无线移动通信系统的主要目标是为移动终端（MTs）提供所需的服务质量，同时提供移动性和普遍性。通过无处不在，我们理解MT随时随地连接到网络的能力，而不考虑接入信道的特性。在本章中，我们将讨论机动性方面的问题。我们提供了一些基本背景的流动性模型，正在用于相关的流动性管理程序的绩效评估，如交接和位置更新。对于切换，因此对于信道保持时间，我们重新审视细胞停留时间的表征。在此基础上，建立了定位区域停留时间的模型。细胞停留时间可视为微观迁移参数，而后者可视为宏观迁移参数；两者都对切换和位置更新算法有重要影响。
The main goals of today’s wireless mobile telecommunication systems are to provide both, mobility and ubiquity to mobile terminals (MTs) with a required quality of service. By ubiquity we understand the ability of a MT to be connected to the network anytime, anywhere, regardless of the access channel’s characteristics. In this chapter we deal with mobility aspects. We provide some basic background on mobility models that are being used in performance evaluation of relevant mobility management procedures, such as handover and location update. For handover, and consequently for channel holding time, we revisit the characterization of the cell residence time. Then, based on those previous results, models for the location area residence time are built. Cell residence time can be seen as a micro-mobility parameter while the latter can be considered as a macro-mobility parameter; and both have a significant impact on the handover and location update algorithms.
