Abstract
There is provided mechanisms for locating wireless devices. A method is performed by a network operator node of cells. The method comprises obtaining an indication to locate wireless devices in a geographical area from a surveillance center node (s102). The method comprises initiating a change of logical group area identity of those of its cells that at least partly overlap with the geographical area (s104), thereby initiating location reporting from those wireless devices located in the geographical area that are in idle mode. The method comprises, in response thereto, receiving location indicating information from the wireless devices in the geographical area (s106).
Claims16
A network operator node of cells for locating wireless devices, the network operator node comprising processing circuitry, the processing circuitry being configured to cause the network operator node to:
- obtain an indication to locate the wireless devices in a geographical area from a surveillance center node;
- initiate a change of logical group area identity of specific cells, of the cells, that at least partly overlap with the geographical area, thereby initiating location reporting and enabling position determination from the wireless devices located in the geographical area that are in an idle mode;
- and in response thereto:
- receive location indicating information and positioning information of the wireless devices in the geographical area.
