Abstract

In a communication system of the present invention, a HeNB measures interference in Step STin an energy saving mode. When judging to have detected the interference by a UE during communication with an eNB in Step ST, the HeNB cancels the energy saving mode and moves to a normal mode in Step STand starts issuing a pilot signal in Step ST. When the UE judges to have detected the pilot signal in Step STand reports the judgment results to the eNB in Step ST, in Steps STto ST, a handover process from the eNB to the HeNB is performed for the UE.
