Radio communication system, radio terminal, radio network, radio communication method and program

A radio terminal that performs measurement based on a measurement condition to be indicated by a radio network, and reports a measurement result including at least a positioning result, comprising:

• a positioning unit that measures a location of said radio terminal;
• a positioning accuracy calculator that calculates a positioning accuracy of the measured location of said radio terminal;
• and
• a measurement reporting controller that controls, in accordance with the calculated position accuracy, execution of at least the reporting of said measurement result to the radio network by the radio terminal, in order to report only said measurement result including a positioning result satisfying said required positioning accuracy.

A radio communication system in which a radio terminal performs measurement based on a measurement condition to be indicated by the radio network and reports a measurement result including at least a positioning result:

• wherein the radio network comprises a required positioning accuracy notifying unit that notifies to the radio terminal a required positioning accuracy related to a condition of a positioning accuracy for controlling execution of at least the reporting of said measurement result to the radio network by the radio terminal;
• and
• wherein the radio terminal comprises:
• a positioning unit that measures a location of said radio terminal;
• a positioning accuracy calculator that calculates a positioning accuracy of the measured location of said radio terminal;
• and
• a measurement reporting controller that compares said required positioning accuracy with said calculated positioning accuracy, and controls, in accordance with the calculated position accuracy, execution of at least the reporting of said measurement result to the radio network by the radio terminal, in order to report only said measurement result including a positioning result satisfying said required positioning accuracy.
