RADIO BASE STATION, MOBILE COMMUNICATION SYSTEM, HANDOVER CONTROL METHOD, AND PROGRAM

摘要

A radio base station that performs radio communication with a mobile station in a cell and that includes: resource management unit that secures resources necessary for radio communication with the mobile station; and communication control unit that, in accordance with a reconnection request from the mobile station, uses the resources secured by the resource management unit to perform reconnection control for establishing radio communication with the mobile station. If a reconnection request is received from the mobile station that takes another radio base station as the connection source in a state in which resources have not been secured by resource management unit, communication control unit interrupts the reconnection control, executes handover with the other base station in order to switch the connection destination of the mobile station from the other base station to its own base station, causes resource management unit to secure resources, and then resumes the reconnection control.
