Abstract
There is provided a solution comprising detecting that a positioning device (400) is within a predetermined control area (402A, 402B) associated with a building (100), acquiring a first sequence (420) of magnetic field measurements carried out by the positioning device (400), wherein the first sequence (420) represents at least one of the magnitude and the direction of Earth's magnetic field (208); determining that an operational environment of the positioning de-vice (400) has changed between an indoor environment and an outdoor environment when a at least one predetermined criterion with respect to the first sequence (420) is met; and causing actuation of a predetermined software function in or with respect to the positioning device (400) when the operational environment of the positioning device (400) has changed.
