Method and monitoring centre for supporting supervision of events

A method and monitoring center (304) for supporting supervision of events in a monitored area (300) based on sensor data (D) reported by sensors over a communication network (302). When the monitoring center (304) detects an abnormal event (E), it identifies a set of sensors (S1-S3) which are potentially impacted by the event, and also identifies network nodes (N1-N3, BS) that are able to communicate sensor data reported by the identified sensors (S1-S3). The monitoring center (304) then instructs (In) the identified network nodes to promote the communication of sensor data reported by the identified sensors. Thereby, transport of the sensor data will be enhanced and it will arrive promptly and properly at the monitoring center, to enable any watching staff to take notice and evaluate the abnormal event as soon as possible.
