OVERLOAD CONTROL SYSTEM FOR AUTOMOBILE TELEPHONE SYSTEM

摘要

PURPOSE:To escape from the state without giving any effect onto an automobile telephone exchange and other radio line control base station in exchange connection by allowing a radio line control base station itself disabling to detect a call signal due to concentrated calls to apply call restriction. CONSTITUTION:Radio line control base stations 2A-2D have a function monitoring the operating state of an incoming radio control line receiving a control signal from a mobile set 3 used in a district controlled by itself and detecting the overload state of the incoming radio control line. In detecting the overload state, a call restriction signal 4 to regulate the call from the mobile equipment 3 to the outgoing radio control line sending the control signal to the mobile equipment is provided. Thus, the congestion state of calls is detected in the unit of the radio line control base stations and the congestion is to be restored by the control of the radio line control base station.
