The optimal location area sizes for the dynamic location area ( DLA ) and movement-based location area ( MBLA ) algorithms were derived using both multi-level location areas and the fluid flow mobility model of planar hexagonal cell topology. 基于二维六边形多级位置区蜂窝网络结构以及液体流动运动模型假设,分别给出动态位置区算法和基于运动的动态位置区算法的优化位置区大小。
