ABSTRACT:
In a mobile telecommunications system, when it is determined that a mobile terminal should be handed over from a first cell (primary cell) to a second cell (target cell), the target cell is chosen based on measurements of link quality in the primary network at the time when it is determined that handover is necessary, as well as on stored data indicative of the respective probabilities that different potential target cells will be the best handover target from a particular primary cell. This enables an appropriate choice of target cell to be made even in a case where it is not possible to make measurements on the target cells at the time when it is determined that handover is necessary (for example because handover is to a target cell that operates at a different frequency from that of the primary cell).
