RADIO BASE STATION DEVICE, RADIO TERMINAL DEVICE, COMMUNICATION SYSTEM, COMMUNICATION CONTROL METHOD, AND COMMUNICATION CONTROL PROGRAM

摘要

PROBLEM TO BE SOLVED: To provide a radio base station device, a radio terminal device, a communication system, a communication control method, and a communication control program which can stabilize communication by appropriately controlling handover operation in the radio terminal device.SOLUTION: A radio base station device 101 comprises a handover instruction unit 12 which receives a response from another radio base station device to a request to perform handover operation of a radio terminal device 202 from the radio base station device to the other radio base station device, and gives an instruction to the radio terminal device 202 to perform the handover operation from the radio base station device to the other radio base station device. On receiving the response, when a predetermined execution condition concerning communication quality between the radio base station device and the radio terminal device 202 is not satisfied, the handover instruction unit 12 cancels or suspends transmission of the instruction to the radio terminal device 202.
