Radio communication system and radio communication terminal

A radio communication system comprising a radio communication terminal and radio communication base stations, wherein

• based on a report from a connected radio communication base station, the radio communication terminal performs a predetermined measurement on other radio communication base stations neighboring the connected radio communication base station and reports a result of the predetermined measurement to the connected radio communication base station, and
• when the radio communication terminal performs a handover, the connected radio communication base station selects a radio communication base station, from among the other radio communication base stations, to be a target of the handover by the radio communication terminal based on the result of the predetermined measurement, and in predetermined circumstances, selects a radio communication base station, from among other radio communication base stations neighboring the connected radio communication base station, for which the predetermined measurement was not performed, to be the target of the handover by the radio communication terminal.
