This project studies extremely-distributed switching control networks for mobile communications, where a system-on-a-on-chip switching system locates at each base-station. This is to contribute to providing high-speed packet communications to high-speed mobile terminals in the future multimedia mobile communication network. This is also to permit accommodation of IP-based high-speed terminals in micro-cellular network which is indispensable for radio resource reuse.This project focused on PON (Passive Optical Network) as an access network for the mobile communication network. The broadcasting mechanism of the PON allows continuous packet communications during the movement among several micro-cells. This report proposes a dynamic logical macro-cells concept, which allows the soft-handover in the logical macro-cell region by broadcasting the identical packet to every base station and wireless link. In addition, the dynamic logical macro-cell can move following the movement of the terminals. This can inhibit bit errors at hard-handover which never falls to happen at the border of the cells. As for the IP-based communications, FA (Foreign Agent) locates beyond several OLTs (Optical Line Terminal)s of PON, and permits terminal movement without FA switch-over in a region of 40 km diameter. This report also presents soft-handover procedure for IP-based terminals. In the dynamic logical macro-cell, an identical broadcasting IP address is used.

该项目研究用于移动通信的极度分布式交换控制网络，其中片上系统交换系统位于每个基站处。这将有助于在未来多媒体移动通信网络中为高速移动终端提供高速分组通信。这也是为了在微蜂窝网络中容纳基于IP的高速终端，这对于无线电资源的再利用是必不可少的。该项目重点关注PON（无源光网络）作为移动通信网络的接入网络。 PON的广播机制允许在多个微小区之间移动期间连续的分组通信。该报告提出了动态逻辑宏小区的概念，该概念允许通过向每个基站和无线链路广播相同的数据包来在逻辑宏小区区域中进行软切换。另外，动态逻辑宏小区可以跟随终端的移动而移动。这可以抑制硬切换时的比特错误，而硬切换时的比特错误永远不会发生在小区的边界处。对于基于IP的通信，FA（外地代理）位于PON的多个OLT（光线路终端）之外，并且允许终端在直径40公里的区域内移动而无需FA切换。该报告还介绍了基于 IP 的终端的软切换过程。在动态逻辑宏小区中，使用相同的广播IP地址。
