Abstract

A method for controlling a call handover between telecommunication networks includes determining whether a User Equipment (UE), in communication with a first network, is engaged in a call attempt when the UE is to be transferred from the first network to a second network, if the UE is engaged in a call attempt, maintaining the UE communicating with the first network, and if the UE is not engaged in a call attempt, initiating the handover from the first network to the second network.
