POSITIONING TIME INTERVAL CONTROL DEVICE AND POSITIONING TIME INTERVAL CONTROL METHOD

摘要

PROBLEM TO BE SOLVED: To change a time interval expected to be positioned and a time interval where a position should be notified according to a moving state and/or a moving rate.;SOLUTION: A positioning time interval control device controlling a time interval measuring a position has an acquisition portion acquiring a moving state and a moving rate of a mobile terminal device, and a positioning time interval-setting portion setting a time interval where a position of the mobile terminal device should be measured based on the moving state and the moving rate of the mobile terminal device acquired by the acquisition portion and a time interval to output position information acquired by the measurement. The positioning time interval-setting portion changes the time interval when the moving state and/or the moving rate of the mobile terminal device changes, so that the mobile terminal device acquires the position information of the mobile terminal device at the time interval set by the positioning time interval-setting portion to output the position information.;COPYRIGHT: (C)2011,JPO&INPIT
