Abstract

An approach is provided for providing efficient power saving schemes for a device and any associated sensors thereon while allowing for various levels of functionalities. A device determines a distance from a location of a device on a route to a checkpoint location on the route based, at least in part, on mapping data associated with the route. Then the device causes an initiation of a sleep mode of operation for at least one location sensor associated with the device. Further, the device causes an initiation of an active mode of operation for the at least one location sensor based, at least one in part, on a determination that the device has substantially traveled the distance, a portion of the distance, or a combination thereof.

Claims

1-38. -38. (canceled)

39. A method comprising:

determining a distance from a location of a device on a route to a checkpoint location on the route based, at least in part, on mapping data associated with the route;

causing, at least in part, an initiation of a sleep mode of operation for at least one location sensor associated with the device; and

causing, at least in part, an initiation of an active mode of operation for the at least one location sensor based, at least one in part, on a determination that the device has substantially traveled the distance, a portion of the distance, or a combination thereof.

40. The method of claim 39, wherein the initiation of the sleep mode of operation is based, at least in part, on a determination that the distance is greater than a predetermined threshold value.

41. The method of claim 39, further comprising:

determining whether to enable the sleep mode of operation based, at least in part, on a user input.

42. The method of claim 39, wherein the initiation of the sleep mode of operation is based, at least in part, on a power level associated with the device, a configuration of the device, or a combination thereof.

43. The method of claim 39, wherein the determination that the device has substantially traveled the distance, a portion of the distance, or a combination thereof is based, at least in part, on odometer data.

44. The method of claim 39, wherein the determination that the device has substantially traveled the distance, a portion of the distance, or a combination thereof is based, at least in part, on speedometer data and a duration of travel.

45. The method of claim 39, wherein the location sensor includes, at least in part, a satellite-based navigation system, a network-assisted navigation system, or a combination thereof.

46. The method of claim 39, further comprising:

causing, at least in part, a monitoring of a current location of the device on the route based, at least in part, on a direction and a distance traveled by the device.

47. The method of claim 46, further comprising:

determining a potential deviation of the device from the route based, at least in part, on the direction, a duration of travel, or a combination thereof; and

causing, at least in part, an initiation of the active mode of operation for the at least one location sensor to update the current location.

48. The method of claim 39, wherein the mapping data is available on the device, via one or more service providers, via one or more content providers, or a combination thereof.

49. An apparatus comprising:

at least one processor; and

at least one memory including computer program code for one or more programs,

the at least one memory and the computer program code configured to, with the at least one processor, cause the apparatus to perform at least the following,

determine a distance from a location of a device on a route to a checkpoint location on the route based, at least in part, on mapping data associated with the route;

cause, at least in part, an initiation of a sleep mode of operation for at least one location sensor associated with the device; and

cause, at least in part, an initiation of an active mode of operation for the at least one location sensor based, at least one in part, on a determination that the device has substantially traveled the distance, a portion of the distance, or a combination thereof.

50. The apparatus of claim 49, wherein the initiation of the sleep mode of operation is based, at least in part, on a determination that the distance is greater than a predetermined threshold value.

51. The apparatus of claim 49, wherein the apparatus is further caused to:

determine whether to enable the sleep mode of operation based, at least in part, on a user input.

52. The apparatus of claim 49, wherein the initiation of the sleep mode of operation is based, at least in part, on a power level associated with the device, a configuration of the device, or a combination thereof.

53. The apparatus of claim 49, wherein the determination that the device has substantially traveled the distance, a portion of the distance, or a combination thereof is based, at least in part, on odometer data.

54. The apparatus of claim 49, wherein the determination that the device has substantially traveled the distance, a portion of the distance, or a combination thereof is based, at least in part, on speedometer data and a duration of travel.

55. The apparatus of claim 49, wherein the location sensor includes, at least in part, a satellite-based navigation system, a network-assisted navigation system, or a combination thereof.
