Abstract

The invention relates to a method for switching a communications link to another channel (handover) in a digital cellular mobile radio systems and a mobile radio system, the time of the handover being determined by a decision algorithm. Roughly generalized, the changeover to a new channel can take place between two radio systems or frequency bands within a radio system (external handover), between two radio cells within a cellular network (intercell handover) or within a radio cell (intracell handover). Each handover case, in turn, can include various type of handover.
