An apparatus calculates a first radio wave strength value, based on a first radio wave between a wireless communication device and a first base station device wirelessly coupled to the wireless communication device, calculates a second radio wave strength value, based on a second radio wave between the wireless communication device and a second base station device, changes at least one of the first radio wave strength value and the second radio wave strength value, when a first wireless communication method used by the first base station device is different from a second wireless communication method used by the second base station device, and, after changing at least one of the first radio wave strength value and the second radio wave strength value, transmits, to the first base station device, a measurement report including the first and second radio wave strength values.
