Claim 16:
17. A network entity, comprising:
at least one transceiver; and
at least one processor, wherein the at least one processor is configured to:
operate a source next generation node B (gNB);
transmit, to an access and mobility management function (AMF), a handover required message for an inter-system handover from a 5G system (5GS) to an evolved packet system (EPS) with the source gNB associated with a target secondary gNB (SgNB), wherein the source gNB and the target SgNB correspond to a same network entity; and
receive, from the AMF, a handover command message,

wherein the handover required message includes a node identifier of the source gNB and a user equipment (UE) identifier allocated at the source gNB, and
wherein the target SgNB is associated with an evolved node B (eNB) in a dual connectivity based on the node identifier of source gNB in the handover required message.
