The efficient use of frequency bands is one of the most important issues in mobile communication systems because the demand for mobile communications is increasing rapidly and the frequency bands for mobile communications are limited. For the efficient use, the cellular concept is usually applied to mobile communication systems. For using the frequency bands more efficiently, the size of a cell becomes smaller and the 2-dimensional cellular system is replaced by the 3-dimensional cellular system.The objective of this research is increasing system capacity of multi-dimensional mobile communication systems by applying Dynamic Cell Allocation and Dynamic Channel Assignment. We obtained the following research results :1.An algorithm for Dynamic Cell Allocation is obtained.2.It is shown that the Dynamic Cell Allocation increases the system capacity.3.Flexible Hybrid Channel Assignment strategy, which is based on neuroalgorithms, is developed.4.Flexible Hybrid Channel Assignment strategy increases the system capacity of multi-dimensional mobile communication systems.From these results, it is shown that new technology is required for developing multidi-mensional mobile communication systems. The future problemis developing the new technology.

频段的有效利用是移动通信系统中最重要的问题之一，因为移动通信的需求迅速增长，而移动通信的频段却是有限的。为了有效地使用，蜂窝的概念通常被应用到移动通信系统中。为了更有效地利用频段，小区尺寸变得更小，二维蜂窝系统被三维蜂窝系统取代，本研究的目的是通过应用动态小区分配和动态信道分配来提高多维移动通信系统的系统容量。研究成果如下：1.提出了一种动态小区分配算法。2.研究表明，动态小区分配提高了系统容量。3.提出了基于神经算法的灵活混合信道分配策略。4.灵活混合信道分配策略提高了多维移动通信系统的系统容量。从这些结果可以看出，开发多维移动通信系统需要新的技术。未来的问题是开发新技术。
