1. A method, performed by a core network, for notification control in a communication system comprising a core network, a radio access network (RAN), and an application function (AF), the method comprising:
establishing a protocol data unit (PDU) session for a user equipment (UE) served by the RAN;
receiving a request from the AF for AN-signaling based notifications indicative of the fulfillment or non-fulfillment of quality of service (QOS) for a QoS flow associated with the PDU session;
sending a notification enable signal to the RAN to enable the RAN to send AN-signaling based notifications notifying a user equipment (UE) of the unfulfillment or re-fulfillment of quality of service (QOS) for a QoS Flow in the PDU session using access stratum signaling; and
wherein the AN-signaling based notification comprises a notification message originating in the RAN and sent directly to the UE by the RAN.
