1. A method for updating a location database of a Radio Signature Positioning Determining Entity (RS-PDE), the method comprising the steps of:

  • a) transferring new location data to the RS-PDE;

    b) correlating the new location data with existing location data of the location database and creating correlated location data;

    c) uploading the correlated location data into the location database;

    d) determining a Figure of Merit (FoM) for a cell associated with at least a portion of the new location data, the FoM relating to an exactitude of a positioning provided by the RS-PDE for positioning requests within the cell; and

    e) if the FoM for the cell is below a pre-defined threshold, tagging the cell for a location data automatic update; and

    wherein steps b) comprises correlating new location data associated to the cell with existing location data associated to the cell.
