Claim 0:
1. A target radio access network (RAN) node, comprising:
at least one memory; and
at least one processor coupled to the at least one memory and configured to:
receive a Handover Request message on a direct interface from a source RAN node, during a handover of a radio terminal from the source RAN node, which connects to a Fifth Generation Core (5G Core) network, to the target RAN node, which connects to the 5G Core network; and
receive a Path Switch Request Acknowledge message including slice information and information related to a PDU session directly from a control plane node in the 5G core network, without involving the source RAN node, in a handover completion phase after receiving the Handover Request message and after the radio terminal connects to the target RAN node, wherein

the slice information includes information which identifies network slice, the network slice being a logical network, and
the information related to the PDU session includes identification information.
