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 15):
A method, comprising:\n receiving an IP multimedia subsystem (IMS) voice over Packet Switched (PS) session is supported indication by a user equipment (UE) in a next generation radio access network (NG RAN) serving cell connected to a 5G core network; performing IMS registration with an IMS server, wherein subsequently the UE is originating or terminating an IMS voice call setup procedure; receiving a handover command when IMS voice over PS (VoPS) session is not supported over the NG RAN service cell with a predefined Quality of Service (QoS) requirement, wherein the UE handovers from the NG RAN serving cell to a target cell that supports IMS VoPS; and continuing the IMS voice call setup procedure through the IMS server in the target cell.
