无线蜂窝网络中的移动性管理是资源优化的主要问题之一。它的目的是跟踪不同位置区域(LAS)或注册区(RAS)中的移动站(MS)，以实现有效的呼叫传递。这些定位策略的优化问题寻求所产生的信令流量的最小化。我们描述了位置管理的三种基本策略：基于距离、基于时间和基于移动，以及它们相应的优化代价。我们强调，计算在呼叫持续时间或呼叫间时间内发生的无线小区交叉或切换的数量是移动性管理分析的基本问题。我们给出了文献中处理这些问题的主要方法，特别强调更新理论来建模这些优化问题的概率结构。
Mobility management in wireless cellular networks is one of the main issues for resource optimization. It is aimed to keep track of Mobile Stations (MSs) in the different Location Areas (LAs) or Registration Areas (RAs) for an efficient call delivery. The optimization issues of these location strategies look for a minimization of the generated signaling traffic. We describe the three basic strategies for location management: distance-based, time-based and movement-based, and their corresponding optimization cost. We emphasize that counting the number of wireless cell crossings or handovers occurring in the call duration time or during inter-call times is a fundamental issue for mobility management analysis. We present the main approaches in the literature to deal with these problems with a special emphasis to renewal theory to model the probabilistic structure of these optimization problems.
