Abstract

A device and method for executing a reserved function using time information extracted from a broadcasting data that provides a correct time in asynchronous mobile communication terminal are provided. The method of executing a reserved function in a mobile communication terminal includes: when a broadcasting function is executed, performing (1) extracting a time information from received broadcasting data, (2) calculating a time difference between a time of the extracted time information and a corresponding operating time of the mobile communication terminal, and (3) storing the calculated time difference as a time difference information; and if a reservation time for executing a specific function is set and when the operating time reaches the set reservation time based on the stored time difference information, executing the specific function.

Claims

1. A method, operable in a mobile communication terminal, for executing a reserved function that is scheduled for execution at a reservation time, the method comprising:

extracting a time information from a received broadcasting data;

calculating a time difference between the extracted time information and an operating time of the mobile communication terminal,

storing the calculated time difference as a time difference information;

calculating a reserved function execution time based on the reservation time and the stored calculated time different information; and

executing the reserved function when the operating time of the mobile communication terminal corresponds to the reserved function execution time.

2. The method of claim 1, wherein the received broadcasting data is at least one Transport Stream (TS) packet.

3. The method of claim 2, wherein the time information is extracted from Program Specific Information (PSI)/System Information (SI) data of the broadcasting data.

4. The method of claim 1, wherein calculating the reserved function execution time comprises:

adding the reservation time and the stored time difference information.

5. The method of claim 1, wherein calculating the time difference-information comprises subtracting the extracted time information from the operating time of the mobile communication terminal.

6. The method of claim 1, wherein the reserved function is a broadcasting reservation recording function.

7. The method of claim 1, wherein the reserved function is at least one of:

a morning call function and a schedule alarm function.

8. A method of executing a reserved function in a mobile communication terminal, the method comprising:

extracting time information from received broadcasting data,

determining a time difference between a current operating time of a clock function and the extracted time information, and

executing the reserved function if a reservation time for executing the reserved function is set and when the operating time of the clock function reaches a calculated reserved function execution time, the calculated reserved function execution time being the sum of the reservation time and the time difference.

9. A device for executing a reserved function in a mobile communication terminal, comprising:

an input unit for providing inputs;

a controller for executing a clock function based on information provided through the input unit, the clock function generating an operating time of the device; and

a broadcasting reception unit for receiving broadcasting data,

wherein the controller extracts time information from a broadcasting data received by the broadcasting reception unit and when a reservation time for executing the reserved function is set, the controller executes the reserved function when the operating time of the device reaches a reserved function execution time, the reserved function execution time being determined using the reservation time and a time difference between the operating time at the time of receiving the broadcast data and the extracted time information.

10. The device of claim 9, wherein the broadcasting reception unit further comprises:

a tuner for tuning to a broadcasting frequency; and

a demodulator for demodulation of the broadcasting data from a radio signal received through the tuner.

11. The device of claim 10, wherein the broadcasting data is at least one TS packet.

12. The device of claim 11, wherein the TS packet is received when a broadcasting function is executed.

13. The device of claim 11, wherein the time information extracted from the broadcasting data is included in a PSI/SI data of the TS packet.

14. The device of claim 9, wherein the controller further comprises at least one oscillator for generation of a clock to execute the clock function.

15. The device of claim 9, wherein the controller:

stores the time difference information.

16. The device of claim 9, wherein the controller:

provides a notification of the time difference, and

adjusts the operating time to a time based on the received broadcasting data in response to an adjustment signal.

17. The device of claim 9, wherein the controller adds a clock function based on the extracted time information and executes the added clock function.

18. The device of claim 17, wherein the controller executes, if a reservation time for executing a specific function is set, the specific function according to an operating time of the added clock function.
