    Abstract: A Next Generation network device receives, from a user equipment device (UE), a Service Request for establishing a Multimedia Priority Services (MPS) session. The Next Generation network device determines whether the Service Request includes a MPS fallback request to request network fallback from a Next Generation network to a Fourth Generation (4G) network for the MPS session. The device causes, based on the Service Request including the MPS fallback request, establishment of the MPS session from the UE device via the 4G network by performing one of: a handover procedure from the Next Generation network to the 4G network, or a Radio Resource Control (RRC) redirection procedure from the Next Generation network to the 4G network.
