Abstract
A radio communication system includes a plurality of base station apparatuses. In the radio communication system, the communication areas of the plurality of base station apparatuses are connected in a loop to form a borderline separating the inside and the outside of a management area. The radio communication system detects a mobile terminal which enters the management area by crossing the borderline on the basis of communication between the base station apparatuses and a mobile terminal.
