Abstract:
A network-based solution of supporting IP multimedia subsystem (IMS) call setup in a next generation system (5GS) is proposed. During an attach or registration area update procedure, a serving base station sends an indication to a UE indicating whether IMS voice over PS session is supported or not. Upon receipt of the indication that IMS VoPS is supported, the UE triggers an IMS registration procedure. However, when an MO/MT call happens, the network determines that the UE may be in conditions where voice service is not supported because the network is not able to provide a successful IMS VoPS over the current serving cell connected to 5G core network. The network then triggers a RAT change or a EPS fallback procedure such that the UE is handover to a target cell that supports IMS VoPS.

Claim (Index 8):
A base station, comprising:\n a radio frequency (RF) transmitter that transmits information related to IP Multimedia Subsystem (IMS) from a base station to a user equipment (UE) in a Next Generation Radio Access Network (NG RAN) serving cell connected to a 5G core network, wherein the information indicates IMS voice over Packet Switched (PS) session is supported over the 5G core network; an RF receiver that receives an IMS call indication via the 5G core network; a Quality of Service (QoS) circuit that determines whether IMS voice over PS (VoPS) session is supported over the NG RAN serving cell with a predefined QoS requirement; and a handover circuit that generates a handover command to the UE upon determining that the current NG RAN serving cell does not support IMS VoPS, wherein the base station triggers a handover for the UE from the current NG RAN serving cell to a target cell that supports IMS VoPS for performing an IMS VoPS call setup.
