Abstract

Provided is a method and system for determining sleep periods within a communications device configured to communicate via a network The method includes analyzing at least one of two or more data fields related to a data unit and determining device sleep periods based upon the analysis. The analysis includes determining whether or not particular MediaFLO Logical Channel data (MLC) is present within an overhead information symbols channel. If MLC data is not present, the device sleeps for a predetermined amount of time.

Claims

1. A method for determining sleep periods within a communications device, comprising:

analyzing at least one of two or more data fields related to a data unit; and

determining device sleep periods based upon the analysis.

2. The method of claim 1, further comprising determining whether data will be available in a subsequent data unit based on the analysis.

3. The method of claim 2, wherein the sleep periods are consecutive sleep periods.

4. The method of claim 3, wherein the sleep periods are separated by awake periods.

5. The method of claim 1, wherein the communicating is based upon orthogonal frequency division multiplexed principles.

6. The method of claim 1, wherein the analyzing occurs within a physical layer of the network.

7. A method for determining sleep periods within a communications device configured to communicate via a network, comprising:

analyzing a data field related to presence of a data unit; and

determining whether data will be available in an ensuing data unit based on the analysis.

8. An apparatus for determining sleep periods within a communications device configured to communicate via a network, comprising:

means for analyzing at least one of two or more data fields related to a data unit; and

means for determining device sleep periods based upon the analysis.

9. The apparatus of claim 8, further comprising means for determining whether data will be available in a subsequent data unit based on the analysis.

10. The apparatus of claim 9, wherein the sleep periods are consecutive sleep periods.

11. The method of claim 10, wherein the sleep periods are separated by awake periods.

12. The method of claim 8, wherein the communicating is based upon orthogonal frequency division multiplexed principles.

13. The method of claim 8, wherein the analyzing occurs within a physical layer of the network.

14. A transceiver configured to determine sleep periods associated with communicating via a network, comprising:

a processor configured to analyze at least one of two or more data fields related to a data unit; and

a timer for determining device sleep periods based upon the analysis.

15. A computer readable medium carrying one or more sequences of one or more instructions for execution by one or more processors to perform a method of determining sleep periods within a communications device, the instructions when executed by the one or more processors, cause the one or more processors to perform the steps of:

analyzing at least one of two or more data fields related to a data unit; and

determining device sleep periods based upon the analysis.

16. The computer readable medium of claim 15, carrying the one of more instructions, further causing the one or more processors to determine whether data will be available in a subsequent data unit based on the analysis.

17. The computer readable medium of claim 15, wherein the sleep periods are consecutive sleep periods.

18. The computer readable medium of claim 17, wherein the sleep periods are separated by awake periods.

19. The computer readable medium of claim 18, wherein the communicating is based upon orthogonal frequency division multiplexed principles.

20. The computer readable medium of claim 15, wherein the analyzing occurs within a physical layer of the network.
