Claim 10:
11. A mobility management entity (MME), comprising:
at least one transceiver; and
at least one processor, wherein the at least one processor is configured to:
receive, from an access and mobility management function (AMF) for a source next generation node B (gNB), a message associated with 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;
transmit, to an evolved node B (eNB), a handover request message for the inter-system handover with the source gNB; and
receive, from the eNB, an acknowledge of the handover request 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,
wherein the handover request message includes the node identifier of the source gNB and the UE identifier allocated at the source gNB, and
wherein the eNB is associated with the target SgNB in a dual connectivity based on the node identifier of the source gNB in the handover request message.
