ABSTRACT:
In a multicellular radio communications network, when a mobile station satisfies a criterion for automatic intercellular handover from a source cell to a target cell, the speed of movement of the mobile station with respect to the base station of the target cell is estimated on the basis of the measured levels of the signal which the mobile station has received from this base station before the handover criterion is satisfied. Depending on the layers of the cells concerned, it is then possible to take account of this speed estimate in order to decide whether or not to trigger intercellular handovers.
