Abstract

In accordance with an example embodiment of the present invention, a method and an apparatus are shown comprising receiving status information of an apparatus, and determining a probability for an update of information related to a position being obtained based on the status information. Based on the determined probability and an elapsed time since a last update of the information related to a position, it is determined whether to activate a receiver in order to obtain the update of information related to a position.

Claims

1. A method comprising:

receiving multiple status information of an apparatus;

determining a cumulative probability for an update of information related to a position being obtained based on the multiple status information; and

determining whether to activate a receiver in order to obtain the update of information related to a position based on the determined probability and an elapsed time since a last update of the information related to a position.

2. The method of claim 1, further comprising at least one of:

a) determining a time when to update the receiver in order to obtain the update of information related to a position;

b) wherein information related to a position comprises information related to a process of calculating a position;

c) wherein information related to a position comprises ephemeris data;

or

d) wherein information related to a position comprises a reference time.

6. The method of claim 2, wherein obtaining the information related to a position comprises receiving a signal from a at least one of:

a) satellite of a global positioning system;

b) wherein obtaining the information related to a position comprises receiving information from a short range radio transceiver;

c) wherein receiving status information of an apparatus comprises receiving connectivity information of a local transmitter;

d) wherein receiving status information of an apparatus comprises receiving handover information of a radio receiver;

e) wherein receiving status information of an apparatus comprises receiving information of an active communication profile;

f) wherein receiving status information of an apparatus comprises receiving information of an active profile of the apparatus;

g) wherein receiving status information of an apparatus comprises receiving information on a connected charger;

or

h) wherein receiving status information of an apparatus comprises receiving information on a sensor reading.

3-5. -5. (canceled)

7-13. -13. (canceled)

14. An apparatus, comprising:

a controller configured to receive multiple status information from the apparatus;

the controller being further configured to determine a cumulative probability for an update of information related to a position being obtained based on the multiple status information;

the controller being further configured to determine whether to activate a receiver in order to obtain the update of information related to a position based on the determined probability and an elapsed time since a last update of the information related to a position; and

the controller being further configured to activate the receiver at the determined time.

15. The apparatus of claim 14, wherein the controller is further configured to determine a time when to update the receiver in order to obtain the update of at least one of:

a) wherein the information related to a position

b) wherein information related to a position comprises ephemeris data;

or

c) wherein information related to a position comprises a reference time.

16. The apparatus of claim 15, wherein the apparatus comprises at least one of:

a) wherein the receiver is a receiver of a global navigation satellite system;

b) wherein the apparatus comprises the receiver;

c) wherein the receiver is a short range radio transceiver;

or

d) wherein the information related to a position comprises information related to a process of calculating a position.

17-21. -21. (canceled)

22. A computer program, comprising:

code for receiving multiple status information of an apparatus;

code for determining a cumulative probability for an update of information related to a position being obtained based on the multiple status information; and

code for determining a time when to activate a receiver in order to obtain the update of information related to a position based on the determined probability and an elapsed time since a last update of the information related to a position was received when the computer program is run on a processor.

23. The computer program according to claim 22, wherein the computer program is a computer program product comprising a computer-readable medium bearing computer program code embodied therein for use with a computer.

24. A computer-readable medium encoded with instructions that, when executed by a computer, perform:

receiving multiple status information of an apparatus;

determining a probability for an update of information related to a position being obtained based on the multiple status information; and

determining a time when to activate a receiver in order to obtain the update of information related to a position based on the determined cumulative probability and an elapsed time since a last update of the information related to a position was received.

25. An apparatus comprising:

means for receiving multiple status information of an apparatus;

means for determining a cumulative probability for an update of information related to a position being obtained based on the multiple status information; and

means for determining a time when to activate a receiver in order to obtain the update of information related to a position based on the determined probability and an elapsed time since a last update of the information related to a position was received.
