Abstract:
1. A radio communication system comprising: at least one base station; a plurality of mobile stations accommodated in said base station; and a line controller connected to said base station for managing communication channels possessed by said radio communication system, said line controller including a first memory for keeping track of each of the communications channels of said system for each base station as to whether each communications channel is occupied or idle, said base station including a second memory for storing at least one of said idle communication channels stored in said first memory as reserved channels, wherein said base station is responsive to a connection request generated from an arbitrary calling mobile station of said mobile stations, said connection request including designation of at least one called mobile station, to designate a reserved channel stored in said second memory included in said base station as a communication channel for at least said calling mobile station to establish a connection with said calling mobile station, and when all of the reserved channels stored in said second memory have already been assigned to communications of mobile stations so that no idle channel is available, said base station issues a request for notification of an idle communication channel to said line controller so that said line controller can assign one of the idle communication channels that are kept track of by said line controller to said base station as a reserved channel.
