Abstract:
An integrated service-area control system for integratedly controlling radio service areas of a plurality of base stations in a mobile communication system which includes an exchange, said plurality of base stations connected to said exchange, and a plurality of radio telephone sets located within the radio service areas of the base stations for communicating with the base stations through spatial radio channels, said exchange comprising:detection means for detecting an abnormal condition in the respective base stations;means, on the basis of a detection result of said detection means, for creating a base-station operation-state table indicative of operation states of the base stations;a base-station state pattern table for registering therein a plurality of patterns indicative of the various operation states of the base stations;a base-station control data table created for each of the patterns for defining the radio service areas of the base stations to match the patterns registered in said pattern table;selection means for comparing said base-station operation-state table with said base-station state pattern table to select one of the patterns optimumly matching contents of said base-station operation-state table;reading-out means for reading out one of said base-station control data tables corresponding to the pattern selected by said selection means; andmeans for transmitting control data of the base-station control data table read out by said reading-out means to the base stations,wherein each of said base stations includes means for setting its own radio service area on the basis of the control data received from the transmission means of said exchange.
