Claim 3:
4. A method performed by an evolved node B (eNB), the method comprising:
receiving, from a mobility management entity (MME), a handover request message for an inter-system handover from a 5G system (5GS) to an evolved packet system (EPS) with a source next generation node B (gNB) associated with a target secondary gNB (SgNB), wherein the source gNB and the target SgNB correspond to a same network entity; and
transmitting, to the MME, an acknowledge of the handover request message,
wherein the handover request message includes a node identifier of the source gNB and a user equipment (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.
