First Claim
1. A positioning control device that determines a current location based on positioning requests from a plurality of applications, comprising:
- a positioning unit configured to determine a current location at a positioning accuracy specified by an application; and
a positioning request management unit configured to return a positioning result obtained by the positioning unit in response to the positioning request from the application,wherein when there is a new positioning request from the application, in a case where a positioning accuracy specified in the new positioning request is equal to or less than a positioning accuracy specified in a prior positioning request, the positioning request management unit is configured to return a positioning result for responding the prior positioning request, in response to the new positioning request.

Abstract
A positioning control device includes a GPS hardware control unit that makes GPS determine a current location at different positioning accuracies, and a positioning request management unit that makes the GPS hardware control unit carry out positioning in response to a positioning request from an application according to a positioning accuracy specified in the positioning request, acquires the positioning result, and returns the acquired positioning result to the application of the request origin. In a case where a positioning accuracy of a new positioning request is equal to or less than a positioning accuracy of a latest positioning result, the positioning request management unit reuses the latest positioning result and returns the latest positioning result in response to the new positioning request.

4. A positioning control method for determining a current location based on positioning requests from a plurality of applications, comprising:
-
a positioning step of determining a current location at a positioning accuracy specified by an application; and a positioning request management step of returning a positioning result obtained in the positioning step in response to the positioning request from the application, wherein when there is a new positioning request from the application, in a case where a positioning accuracy specified in the new positioning request is equal to or less than a positioning accuracy of a latest positioning result determined for a prior positioning request, the latest positioning result for responding the prior positioning request is returned in response to the new positioning request in the positioning request management step.
