Abstract

A method and device for position determination, in which one or more application (201, 202) requests a positioning method selection device (204) for positioning data. The positioning method selection device provides an application with positioning data using one or more positioning method (205 to 209) in accordance with settings defined by the application and/or the user. The positioning method selection device (204) receives a positioning request from an application (201, 202), forms a parameter or parameters indicating the quality of positioning requested by the application, compares the quality of positioning data provided by the positioning methods with the positioning quality required by the application, and sends positioning data to the application (201, 202) in response to the positioning request.
