Claim 13:
14. A system, comprising:
a processor configured to:
generate a handover request including a handover reason of no presence of quality of service (QoS) flow for a voice signal to a user equipment (UE),
receive a handover command generated by an access and mobility management function (AMF) to transfer the UE from one or more 5G systems (5GS) to an Evolved Packet System (EPS) based on the handover request,
after a flow of the voice signal has terminated, re-establish a connection with the UE to reconnect the UE to the one or more 5GS, wherein the connection is re-established based on a target ID of a base stations (BS); and

a radio frequency integrated circuit, coupled to the processor, configured to transmit the handover request to the AMF, and the handover command to the UE for the UE to establish a connection with the EPS.
