Method and apparatus for predicting and pre-fetching location information
View Patent ↗An approach is provided for predicting and pre-fetching location information. A pre-fetching manager determines a predicted location associated with a device. Next, the pre-fetching manager retrieves location information based, at least in part, on the predicted location. Then, the pre-fetching manager determines to cache the location information at the device.

determining a planned route of travel based, at least in part, on an application, a service, or a combination thereof associated with the device; and
determining the predicted location based, at least in part, on the planned route of travel.
6. A method of claim 1 , further comprising:
determining at least one event associated with the device; and
locally and/or remotely determining actions that result in the determination of the predicted location, the determination to retrieve the location information, the determination to cache the location information, or a combination thereof based, at least in part, on the at least one event.
7. A method of claim 1 , further comprising:
determining one or more location-based applications executing on the device; and
determining the predicted location, at least a portion of the location information, or a combination thereof based, at least in part, on the one or more location-based applications.
8. A method of claims 1 , further comprising:
acting on an execution of one or more location-based applications;
at least one determination of at least a portion of the location information based, at least in part, on available information regarding a current location of the device; and
providing the at least a portion of the location information to the one or more location-based applications.
9. 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 predicted location associated with a device;
determine a hierarchy of location information with respect to a plurality of accuracy levels, including determine at least one hierarchically lower accuracy position at a time of determine a hierarchically higher accuracy position with respect to the predicted location;
to store the hierarchy of location information at the device; and
display a current location information of the device based, at least in part, on a highest accuracy position of the stored hierarchy of location information.
10. An apparatus of claim 9 , wherein the location information is reverse geo-coded information.
11. An apparatus of claim 9 , wherein the plurality of accuracy levels of the hierarchy is associated with respective granularities of the predicted location.
12. An apparatus of claim 9 , wherein the apparatus is further caused to:
receive a request for at least a portion of the location information, the request specifying at least in part a determined location of the device; and
determine the at least a portion of the location information based, at least in part, on the determined location, an accuracy associated with the determined location, or a combination thereof.
13. An apparatus of claim 12 , wherein the apparatus is further caused to:
determine at least one change to the accuracy associated with the determined location; and
determine to update the at least a portion of the location information based, at least in part, on the at least one change.
14. An apparatus of claim 9 , wherein the apparatus is further caused to:
determine the predicted location based, at least in part, on a current location of the device, context information associated with the device, a history of locations associated with the device, or a combination thereof.
15. An apparatus of claim 9 , wherein the apparatus is further caused to:
determine a planned route of travel based, at least in part, on an application, a service, or a combination thereof associated with the device; and
determine the predicted location based, at least in part, on the planned route of travel.
16. An apparatus of claim 9 , wherein the apparatus is further caused to:
determine an event associated with the device; and
cause, at least in part, actions that result in the determination of the predicted location, the determination to retrieve the location information, the determination to cache the location information, or a combination thereof based, at least in part, on the event.
17. An apparatus of claim 16 , wherein the event includes, at least in part, an initial use of the device, an activation of the device, a change in an online status of the device, a change in an operator network associated with the device, or a combination thereof.
18. An apparatus of claim 9 , wherein the apparatus is further caused to:
determine one or more location-based applications executing at the device; and determine the predicted location, at least a portion of the location information, or a combination thereof based, at least in part, on the one or more location-based applications.
