MOBILE COMMUNICATION SYSTEM AND ITS BASE-STATION DEVICE

摘要

A mobile communication system in which an integral controller (ISa1) is provided between a group of base stations (CSa1, CSa1, ...) arranged in an area where the traffic density is low and a public digital network (INW), I' lines of the base stations (CSa1, CSa1, ...) are connected to the controller (ISa1), and the controller (ISa1) is connected to the network (INW) through an I', line having a smaller number of channels than the total number of channels of the I' lines between the base stations (CSa1, CSa1, ...) and the controller (ISa1). The controller (ISa1) performs various kinds of control of incoming and outgoing calls to and from the base stations (CSa1, CSa1, ...).
