A method for determining the location of a mobile device within a building, - in which a respective mobile device (MGX) by the user (U) within the space (X) is moved, - in which the motion sensor (BS) of the respective mobile device (MGX) a movement of the device (MGX) and a motion detector (BM) of at least one chamber (X) of the building installed respective room unit (RGX) a movement in the at least one space (X) recognize - in which each room unit (RGX) a radio message (FM) sends with its own position, - at which the respective mobile device (MGX) the radio message (FM) and to thereby measure their signal strength, - at which the respective mobile device (MGX) on the one hand recognizes using a statistical method, when the signal strength of the just-received radio message is high, and on the other hand, if the by the motion detector (BM) of the respective room unit (RGX) motion detected with the by the motion sensor (BS) of the respective mobile device (MGX) detected motion are correlated in time, and it concludes that the reported just in the at least one chamber (X) movement is probably its own and that the respective mobile device itself (MGX) is in the at least one chamber (X) and in the vicinity of the respective room unit (RGX) or its position.
