ENHANCED FINDING OF SUBSCRIBERS IN COMMUNICATIONS SYSTEM
First Claim
1. A method of providing subscriber location information in a communications system, the method comprisingperforming a prioritization act according to predetermined prioritization criteria, wherein the prioritization act is performed on the basis of passive location data received in a gateway node from an operator network, the passive location data including location information on user terminals in the operator network;
- selecting, on the basis of said prioritization act, one or more of said user terminals as polling priority user terminals;
requesting, on the basis of said selecting, one or more network nodes in the operator network to perform an act for generating updated passive location data;
receiving the updated passive location data in the gateway node, the updated passive location data including information on detected polling priority user terminals; and
storing the received updated passive location data in the gateway node.

Abstract
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).
