Abstract

Methods and apparatus are provided for handover of a UE from a source node connected to a first core network to a target node connected to a second core network. The UE receives, from the source node, a mobility command including an indication of the radio access technology (RAT) used by the target node and a message container containing configuration information for the target node. The UE further determines, based on the indication of the RAT used by the target node, whether to treat the handover as an inter-RAT handover or as an intra-RAT handover with a core network change, and performs a radio resource control procedure for one of an inter-RAT handover or an intra-RAT handover with a core network change based on the determination.
