Abstract

Provided is a method and apparatus for managing a schedule of a terminal based on a local time. It is possible to prevent schedule information from a schedule of a terminal from being repeatedly processed or from being missed, when the local time changes due to the movement of the terminal into another time zone or due to daylight saving time. It is also possible to manage a schedule by determining if the schedule has changed during a period between a time before the change and the changed time.

Claims

1. A method for managing a schedule of a terminal based on a local time, the method comprising:

determining if the local time changes;

if the local time changes to an earlier time, determining if there is schedule information that has already been processed that will be processed again as a result of the local time change;

if the local time changes to a later time, determining if there is unprocessed schedule information that was to be processed during a period between the changed local time and the local time before the change of the local time; and

preventing an already-processed schedule information from being processed again and reporting the unprocessed schedule information to a user.

2. The method as claimed in claim 1, further comprising changing a schedule state for schedule from an active state to an inactive state, so as to prevent the already-processed schedule information from being processed again.

3. The method as claimed in claim 1, further comprising storing a time difference value corresponding to the time between the changed local time and the local time before the change of the local time, and changing a schedule state for the schedule from an inactive state to an active state when the time difference value counted down becomes zero.

4. The method as claimed in claim 2, further comprising storing a time difference value corresponding to the time between the changed local time and the previous local time before changing of the local time, and changing the schedule state of the schedule from the inactive state to an active state when the time difference value counted down becomes zero.

5. The method as claimed in claim 1, further comprising storing an absolute time corresponding to the local time before the change of the local time, and changing a schedule state for the schedule in the inactive state to an active state when the changed local time becomes the same as the local time before the change of the local time.

6. The method as claimed in claim 2, further comprising storing an absolute time corresponding to the local time before the change of the local time, and changing the schedule state for the schedule from the inactive state to an active state when the changed local time becomes the same as the local time before the change of the local time.

7. The method as claimed in claim 1, further comprising storing a processed time and a condition for the already-processed schedule information.

8. A method for managing a schedule of a terminal based on a local time, the method comprising:

inputting a schedule into a terminal from an external server or by a user;

determining if schedule information within the schedule is identical with schedule information already-processed in the terminal, when the inputted schedule is active; and

executing corresponding schedule information when the schedule information within the schedule is not identical with the schedule information already-processed in the terminal.

9. The method as claimed in claim 8, further comprising storing a time and a condition for the executed schedule information.

10. The method as claimed in claim 8, further comprising checking the schedule information and a state for the input schedule when the schedule information within the schedule is identical with the schedule information already-processed in the terminal.

11. The method as claimed in claim 10, wherein the checking of the schedule information is repeated.

12. An apparatus for managing a schedule based on a local time, the apparatus comprising:

a storage device for storing information for the schedule; and

a controller for changing time within a terminal after receiving a changed local time when the local time changes, recognizing the changed time, and determining if the schedule inputted in the storage device is to be executed.

13. The apparatus as claimed in claim 12, wherein the controller further comprises a device management enabler client for communicating with an external server.

14. The apparatus as claimed in claim 12, wherein the storage device stores a time difference value between the changed time and the time before the change of the time.

15. The apparatus as claimed in claim 12, wherein the storage device separately stores the time before the change of the local time.

16. The apparatus as claimed in claim 12, wherein the storage device stores a time and a condition of the schedule to be executed.
