When receiving a connection request from a radio terminal (20), a radio base station (10-1) transmits a resource reservation request to a radio base station (10-2) and a radio base station (10-3) if a resource cannot be reserved in the radio base station (10-1), and receives a resource reservation response indicating whether or not the resource can be reserved. When the resource can be reserved in the radio base station (10-2) or the radio base station (10-3), the radio base station (10-1) establishes a service channel via the radio base station (10-1) and performs control for causing the radio terminal (20) to perform a handover to the radio base station (10-2) or the radio base station (10-3). |
