Abstract

A method, apparatus and computer program product are provided that enable a method for providing location information to be selected based upon a determination, such as a minimization, of the consumption of location server resources that will be consumed by the method. The method, apparatus and computer program product may determine a selected location method from a set of location methods based on predetermined selection criteria. Specifically, the selected location method may be selected to meet a location accuracy requirement specified in a request for location information while consuming a determinable, such as a minimum, amount of resources. The predetermined selection criteria may be updated over time such that method, apparatus and computer program product are self-learning.

7. A method according to claim 6, wherein updating the predetermined selection criteria comprises associating information about a location of an event generating an update with the update.

8. A method according to claim 5, wherein updating the predetermined selection criteria comprises updating the resource consumption associated with the selected location method.

9. A method according to claim 8, wherein updating the predetermined selection criteria comprises associating information about a location of an event generating an update with the update.

10. A method according to claim 5, wherein determining the selected location method comprises using initial information regarding a location of the mobile terminal.

11. A method according to claim 10, wherein the initial information regarding the location of the mobile terminal includes an identity of a cell serving the mobile terminal.

12. A computer program product comprising at least one computer-readable storage medium having computer-readable program code portions stored therein, the computer-readable program code portions comprising:

a first executable portion for initiating the method by determining a selected location method from a set of location methods based on predetermined selection criteria;

a second executable portion for communicating the selected location method to a position determining entity, the selected location method used to determine location information of a mobile terminal;

a third executable portion for updating the predetermined selection criteria responsive to information received from the position determining entity, the information being descriptive of the predetermined selection criteria based at least on employment of the selected location method with respect to the determined location information, wherein the updating occurs prior to a re-initiation of the method; and

a fourth executable portion for determining a new selected location method from the set of location methods based on the updated predetermined selection criteria.

13. A computer program product according to claim 12, further comprising a fifth executable portion for an initial operation of receiving a request for location information, the request being associated with a requested location accuracy.

14. A computer program product according to claim 13, further comprising a sixth executable portion for determining the set of location methods from a plurality of location methods, the set of location methods including location methods having an expected accuracy at least equal to the requested location accuracy.

15. A computer program product according to claim 12, wherein the predetermined selection criteria comprise an expected accuracy and a resource consumption, and the first executable portion includes instructions for selecting the selected location method as one of the set of location methods having the expected accuracy at least equal to the requested location accuracy and a resource consumption that meets a predefined resource usage criteria.

16. A computer program product according to claim 15, wherein the third executable portion includes instructions for updating the expected accuracy based on accuracy information associated with the selected location method.

17. A computer program product according to claim 15, wherein the third executable portion includes instructions for updating the resource consumption associated with the selected location method.

18. An apparatus comprising a processor configured to control a location method selection module, wherein the location method selection module is configured to:

initiate a process by determining a selected location method from a set of location methods based on predetermined selection criteria;
