Abstract: It is presented a method for determining a location of a mobile communication terminal. The method is performed in a location determiner and comprises the steps of: obtaining, using a first location source, a first location indicator of the mobile communication terminal; obtaining using a second location source, a second location indicator of the mobile communication terminal; determining an inconsistency condition to be true when one, and only one, of the first and second location indicators indicates the mobile communication terminal to be located within the coverage of its home network; and when the inconsistency condition is true, disregarding the location indicator indicating the mobile communication terminal to be located within the coverage of its home network.

Abstract: A method of monitoring monitored locations by means of a monitoring system. The monitoring system comprises a plurality of monitoring modules 1, each of which has a light-sensitive sensor for monitoring the monitored locations. The monitoring system further comprises a remote monitoring station 3 with an operator. The method comprises the steps of recording by each of the monitoring modules 1 an image of the monitored location associated with the monitoring module 1, extracting in each of the monitoring modules an area in the recorded image that differs from a reference image, and extracting in each of the monitoring modules an object from the area.

Abstract: A method and a device for managing image information in a monitoring system. The monitoring system comprises at least one monitoring module (1) for monitoring a monitored location and a remote recipient unit (3). The method comprises the steps of recording an image of the monitored location with the monitoring module (1), segmenting out a distinct region by comparing the recorded image with a reference image in the monitoring module (1), creating an outline shape in the monitoring module which represents the edge of the distinct region, transmitting data which represents the outline shape to the recipient unit (3), recreating the outline shape in the recipient unit by means of said transmitted data, and displaying the outline shape visually in the recipient unit.
