Abstract

There are provided measures for detection and inhibition of multiple consecutive inter-RAT ping-pong handovers (also called handover bounces). Such measures exemplarily include detecting multiple consecutive ping-pong handovers of a communication endpoint between two radio access technologies, wherein a ping-pong handover includes a handover from one of said two radio access technologies to the other of said two radio access technologies and a handover from the other of said two radio access technologies to the one of said two radio access technologies, and causing immediate inhibition of certain handovers of said communication endpoint.
