ABSTRACT:
In a mobile radio telecommunications system having a switching unit, a control station connected to the switching unit, a plurality of base stations connected to the switching unit, and a plurality of mobile stations connected to the base stations by radio channels, the base stations are each situated at private property, and each includes a controller for determining a direction in which a mobile stations is moving. The controller receives via the control station and switching unit information representative of the levels at which the individual base stations have received a radio wave from a mobile station, compares the received levels, determines, based on the result of comparison, that one of the base stations having the highest received level currently covers the mobile station, and determines a direction in which the mobile station is moving on the basis of a transition of the highest received level.
