Abstract: Systems and methods establish and maintain end-to-end priority of wireless multimedia priority service (MPS) sessions terminating to subscribers without high priority access. A network device a wireless core network receives a request to establish a bearer for an elevated priority call. The elevated priority call originates from a first user equipment (UE) device in a Radio Resource Control (RRC) connected mode having an elevated priority status and terminates at a second UE device in a RRC connected mode having a non-elevated priority status. The network device determines modification of a terminating bearer for the second UE device is necessary to preclude preemption during periods of network congestion and identifies a high priority parameter of an originating bearer for the first UE device. The network device initiates establishment of the terminating bearer to match the high priority parameter of the originating bearer.
