Abstract

A method and an apparatus for reminding a calendar schedule and a recording medium are provided. First, a schedule and a location of an event are set in a calendar, and first positioning information of the location is obtained. Then, second positioning information of a current location of a mobile device is obtained. Next, the current location is determining whether to be within a signal range of a signal source. Once the current location is within the signal range, the time for moving from the location with the second positioning information to the location with the first positioning information is calculated. Finally, a reminding time is set according to the transferring time, and a reminding action is taken at the reminding time. Thereby, the reminding time of the event can be dynamically adjusted to avoid delay caused when the mobile device is too far from the event location.

when determined by the mobile device that the current location exceeds the signal range of the signal source;

calculating a transferring time of moving from the current location with the second positioning information to the location of the event with the first positioning information;

advancing from the first reminding time to a second reminding time which is earlier than the first reminding time by subtracting the transferring time from the first reminding time to generate the second reminding time; and

performing a reminding action of the event at the second reminding time.

2. The method according to claim 1, wherein the second positioning information is obtained through positioning of a positioning module.

3. The method according to claim 1, wherein the location of the event is set by selecting or picking a specific location in an electronic map.

4. The method according to claim 1, wherein the first positioning information is obtained by inquiring an electronic map according to the location, wherein the electronic map comprises positioning information of a plurality of locations.

5. The method according to claim 1, wherein the first positioning information is obtained by inquiring a positioning information database according to the location, wherein the positioning information database comprises positioning information of a plurality of locations.

6. The method according to claim 1, wherein the step of calculating the transferring time for moving from the location with the second positioning information to the location with the first positioning information comprises:

calculating the transferring time for moving from the location with the second positioning information to the location with the first positioning information by referring to road speed limit information in an electronic map or a position information database or by referring to walking pace.

7. The method according to claim 6, wherein the step of calculating the transferring time for moving from the location with the second positioning information to the location with the first positioning information by referring to the road speed limit information in the electronic map comprises:

calculating a distance between the location with the second positioning information and the location with the first positioning information; and

dividing the distance by the road speed limit information or walking pass to obtain the transferring time.

8. The method according to claim 1, wherein the step of calculating the transferring time for moving from the location with the second positioning information to the location with the first positioning information comprises:

planning a path for moving from the location with the second positioning information to the location with the first positioning information; and

calculating the transferring time for moving from the location with the second positioning information to the location with the first positioning information by referring to road speed limit information of one or multiple roads which are passed through by the path.

9. The method according to claim 1, wherein before the step of obtaining the second positioning information of the current location of the mobile device, the method further comprises:

setting a turn-on time for turning on the mobile device to obtain the second positioning information of the current location of the mobile device, and turning on the mobile device to obtain the second positioning information of the current location of the mobile device at the turn-on time, wherein the turn-on time is a time earlier than the schedule of the event for a fixed length of time or is a specific time set by a user.

10. The method according to claim 1, wherein the reminding action comprises broadcasting or displaying a reminding message of the event.

20. The method of claim 1, wherein the first reminding time is the event time subtracted by a predetermined time.

11. An apparatus for reminding a calendar schedule, comprising:

a calendar module, for setting a schedule and a location of an event, setting a first reminding time of the event in the calendar, and obtaining first positioning information of the location of the event;

a positioning module, for obtaining second positioning information of a current location and determining whether to advance the first reminding time based on whether the current location is within a signal range of a signal source which provides a connection service for the apparatus at the event location, wherein the signal source is either a base station or a Wi-Fi access point;

a calculation unit, for calculating a transferring time of moving from the current location with the second positioning information to the location of the event with the first positioning information and advancing from the first reminding time to a second reminding time which is earlier than the first reminding time by subtracting the transferring time from the first reminding time to generate the second reminding time when the positioning module determines that the current location exceeds the signal range of the signal source at the event; and

a reminding module, for performing a reminding action of the event at the second reminding time when the positioning module determines that the current location exceeds the signal range of the signal source at the event.

12. The apparatus according to claim 11, wherein the second positioning information is obtained through positioning of the positioning module.

13. The apparatus according to claim 11, wherein the location of the event is set by selecting or picking a specific location in an electronic map.

14. The apparatus according to claim 11, further comprising:

a storage unit, for storing an electronic map or a positioning information database, wherein the electronic map and the positioning information database comprise positioning information of a plurality of locations,

wherein the first positioning information is obtained by inquiring the Electronic map or the positioning information database.

15. The apparatus according to claim 11, further comprising:
