<p>In the present solution, a gateway node (GMLC-I, PDC) of a communications system (S) receives a find-subscribers-in-area request from an application node (LAP), and a prioritization act is performed according to predetermined prioritization criteria. The prioritization act is performed on the basis of passive location data received in the gateway node (PDC), and one or more user terminals are selected as polling priority user terminals (UE, UE2). On the basis of said selection, a core network node (MSC/VLR) is requested to perform an act for generating updated passive location data. Thus, the gateway node (PDC) receives updated passive location data including information on detected polling priority user terminals (UE, UE2). On the basis of the updated data, the gateway node (GMLC-I, PDC) is able to provide information on the detected user terminals (UE, UE2) to the application node (LAP).</p> |
