Abstract

Disclosed is a mobile terminal capable of interworking a navigation function with a schedule management function. If a user previously registers schedule information including the origin, destination, appointment date/time and schedule alarm time, the mobile terminal will automatically generate an alarm when the schedule alarm time is reached on the date of appointment. Also, the mobile terminal displays an optimal route to the destination and time information to help the user to reach the destination at a desired time. To display the time information (for example, remaining time to reach the destination), the mobile terminal measures the traveling speed of the user and calculates the remaining time to reach the destination based on the measured traveling speed.

Claims

1. A method for route guidance on a mobile terminal capable of interworking schedule management and navigation functions, which comprises the steps of:

estimating an optimal route and a time to get to a destination based on schedule information inputted by a user;

obtaining a departure time in consideration of the estimated time to get to the destination and setting an alarm for the departure time;

generating an alarm when the departure time is reached;

guiding the optimal route to the destination;

calculating a remaining time to reach the destination according to the traveling speed of the mobile terminal; and

comparing the calculated time with the schedule information and outputting a route guiding message.

2. The method as claimed in claim 1, wherein said schedule information includes at least one of a scheduled appointment, scheduled date and time, schedule alarm time, desired alarm sound and route setting information.

3. The method as claimed in claim 1, wherein said route setting information includes at least one of an origin, destination, means of travel, desired arrival time and route guiding information.

4. The method as claimed in claim 3, wherein said means of travel is any of car, bus, subway, public transportation and foot.

5. The method as claimed in claim 1, wherein registration of said schedule information includes:

determining whether a route setting menu is selected to implement a navigation function in connection with the inputted schedule information; and

when the route setting menu is selected, inputting route setting information.

6. The method as claimed in claim 5, further comprising the steps of:

sending the route setting information which includes an origin, destination, means of travel, desired arrival time to a navigation server; and

receiving information about a departure time obtained in consideration of the time to get to the destination and an optimal route from the server.

7. The method as claimed in claim 1, wherein said estimation of the time to get to the destination includes:

determining whether at least one means of travel has been selected;

measuring a speed of the selected means of travel; and

calculating the remaining time to reach the destination based on the measured speed.

8. The method as claimed in claim 1, further comprising the steps of:

determining whether a desired arrival time has been set;

if the desired arrival time has been set, comparing the remaining time to reach the destination with the desired arrival time;

determining whether a user can reach the destination by the desired arrival time; and

if it is determined that the user cannot reach the destination by the desired arrival time, notifying the user of an arrival delay.

9. The method as claimed in claim 8, wherein said arrival delay is notified through output of a voice message.

10. The method as claimed in claim 8, further comprising the step of requesting for information about a new route when it is determined that the user cannot reach the destination by the desired arrival time.

11. The method as claimed in claim 10, further comprising the step of requesting for information about a new route via another means of travel.
