Abstract
A technique for preparing User Equipment, UE, mobility from a 4G network to a 5G network for a UE moving from a 2G/3G network to the 5G network via the 4G network is disclosed. A method implementation of the technique is performed by a network node and comprises triggering terminating one or more Packet Data Network, PDN, connections associated with the UE when the UE moves from the 2G/3G network to the 4G network forcing the UE to reestablish connectivity with the 4G network prior to moving from the 4G network to the 5G network.
