    • In a mobile communication system, even when cells formed by fixed radio base stations are separated from each other, the switching operation between the cells is easily carried out to conduct continuous communication. A first-end radio device mounted in a first-end section of a mobile unit and linked with one of fixed radio base stations or a last-end radio device mounted in a last-end section of a mobile unit and linked with one of fixed radio base stations is selected. A communication network is established between the first-end or last-end radio device thus selected and a plurality of mobile terminals in the mobile unit. This makes it possible to construct a communicable zone (a virtual cell) on the mobile unit and hence elongates the ranges of cells formed by the base stations.
    • 在移动通信系统中,即使由固定无线基站形成的小区彼此分离,也容易进行小区之间的切换操作,进行连续的通信。 一种安装在移动单元的第一端部分并与固定无线电基站之一或最后端无线电装置之一连接的第一端无线电装置,其安装在移动单元的最后端部分中并与固定无线基站中的一个连接 选择无线基站。 在这样选择的第一端或最后端无线电设备和移动单元中的多个移动终端之间建立通信网络。 这使得可以在移动单元上构建可通信区域(虚拟小区),并因此延长由基站形成的小区的范围。
