Abstract

A technique for preparing User Equipment, UE, mobility from a 4G network to a 2G/3G network for a UE moving from a 5G network to the 2G/3G network via the 4G network is disclosed. A method implementation of the technique is performed by a network node after the UE has moved from the 5G network to the 4G network and includes triggering, for each of one or more bearers handed over from the 5G network to the 4G network for the UE, an update bearer procedure to provide one or more 2G/3G Quality of Service, QoS, parameters to the UE required to hand over the respective bearer to the 2G/3G network when the UE moves from the 4G network to the 2G/3G network.
