Patent ID: 8380208

Claim:
A terminal device comprising: a trigger judging section judging, on the basis of a result of comparison between a reception quality of a macrocell and a reception quality of a small cell in the macrocell, whether an event trigger for performing handover from the macrocell to the small cell has occurred or not; a first measurement result reporting section transmitting a first measurement result report which includes a physical cell ID indicating a small cell for which the event trigger has occurred, to a base station of the macrocell; a proper cell ID detecting section detecting a proper cell ID for uniquely identifying the small cell for which the event trigger has occurred, on the basis of measurement setting information transmitted from the base station of the macrocell as a response to the first measurement result report; a second measurement result reporting section transmitting a second measurement result report which includes the detected proper cell ID, to the base station of the macrocell; and a report transmission controlling section controlling, on the basis of a reception quality of a first small cell for which an event trigger has occurred earlier and a reception quality of a second small cell for which an event trigger has occurred later, transmission of the first and second measurement result reports of the first and second small cells so as to reduce the frequency of transmission of the measurement result reports when the event triggers have continuously occurred, wherein: the report transmission controlling section performs control to cancel transmission of the second measurement result report of the first small cell and prioritize transmission of the second measurement result report of the second small cell in the event that the reception quality of the second small cell is higher than the reception quality of the first small cell, and performs control to delay transmission of the first measurement result report of the second small cell and transmit the second measurement result report of the first small cell and the first measurement result report of the second small cell together in the event that the reception quality of the second small cell is lower than the reception quality of the first small cell.
