MOBILE COMMUNICATION SYSTEM AND ITS BASE-STATION DEVICE

摘要

In a mobile communication system according to this invention, an integrated control apparatus (ISa1) is arranged between a plurality of base stations (CSa1, CSa1,...) arranged in an area with a low traffic density, and a public digital network (INW), the integrated control apparatus (ISa1) accommodates I' lines of the base stations (CSa1, CSa1,...), the integrated control apparatus (ISa1) and the public digital network are connected via I' lines having a smaller number of channels than the total number of channels of the I' lines, and the integrated control apparatus (ISa1) performs various kinds of control for call origination/termination with the base stations (CSa1, CSa1,...). <IMAGE>
