Mobile terminal and schedule management method using the same

A schedule management method using a mobile terminal, comprising:

• setting, by a controller, a schedule including an alarm time, planned event time, planned event and destination;
• receiving, by a GPS module, location information of a destination of the schedule through a map search feature;
• determining, by the controller at an alarm time of a current schedule, whether a preceding schedule is pending between the alarm time and a planned event time of the current schedule;
• computing, by the controller, an estimated travel time from a destination of the preceding schedule to a destination of the current schedule when preceding schedule is pending;
• outputting an alarm, by an audio processor, and display unit the computed estimated travel time and the current schedule at a planned event time of the preceding schedule at or after the alarm time of the current schedule;
• repeatedly computing, by the controller, a tentative estimated travel time between the current location of the mobile terminal and the destination of the current schedule at regular time intervals from the alarm time to the planned event time of the current schedule;
• and
• issuing an alarm, by the audio processor, when the tentative estimated travel time is greater than the difference between the estimated travel time and a preset time duration, an alarm.

A mobile terminal comprising:

• an input unit for inputting a schedule composed of an alarm time, planned event time, planned event, destination, and transportation means;
• a wireless unit for receiving location information of a destination of a schedule from a map search feature;
• a global positioning system (GPS) module for receiving GPS satellite signals to compute a current location of the mobile terminal at an alarm time of a current schedule;
• a control unit for computing a first estimated travel time from the current location of the mobile terminal to a destination of the current schedule and for calculating a second estimated travel time from a destination of the preceding schedule to the destination of the current schedule when the preceding schedule is pending between the alarm time and the planned event time of the current schedule;
• a display unit for displaying the computed first and second estimated travel time and the current schedule;
• and
• an alarm unit for producing an alarm at an alarm time of a schedule.
