Independent cell system of forward and reverse links

摘要

A radio communication system includes: a plurality of forward base stations each forming a macrocell; a plurality of reverse base station each forming a microcell in the associated macrocell; and a mobile communication control office connected between the forward base stations and a public or local area network. The mobile communication control office monitors the received signal's levels of signals sent from portable wireless terminals located in the reverse base stations, thereby specifying each reverse base station which is to exercise jurisdiction over the associated portable wireless terminals and performing the handover control. Since the reverse base station is installed every microcell, the transmitted power of each portable wireless terminal has only to be weak. Thus, the installation number of forward base stations and mobile communication control offices is increased, whereby the service area can be readily enlarged.
