Abstract (in Japanese) (See Japanese page) 
(in English) In recent years, a variety of wireless standards are enacted as a function of the distance and the usage. However, complex processing is needed to handover between two or more standards in seamlesses. In addition, there is a problem the terminal cost increases because the chipset is different. Moreover, because the diversification of the standard causes the increase of the guard band cost, it is no good policy from the view point of the frequency use efficiency. In accord with this, we proposed the hybrid network system that did not depend on the distance in this paper. This system had features integrated by using TD-CDMA in the same frequency band. We arranged some simple base stations that were called mini base stations on a conventional celluar network. And we proposed "MODE" system that controled the slot appropriately in each mini base station based on the interference from central base station. As a result, we realized integrating two or more networks, improving flexibility of changing downlink and uplink slot ratio and increasing the capacity of the network effectively.
