1. A method comprising:
receiving, by a session management function (SMF) module, a signaling indicator from a user device, wherein the signaling indicator comprises data associated with one or more preferences of the user device, wherein the signaling indicator is inferred using a reflective mapping;
receiving, from a network element by the SMF module, a quality of service notification associated with the user device;
determining, by the SMF module based on the signaling indicator and the quality of service notification, whether to provide the quality of service notification to the user device, wherein the signaling indicator is received via a non-access stratum message during a protocol data unit session, wherein determining whether to provide the quality of service indicator and quality of service notification comprises:
determining whether the signaling indicator indicates that the quality of service notification should be provided to the user device based on the quality of service notification being associated with a change in one or more predefined quality of service parameters and a change in one or more predefined quality of service profiles; and
determining whether the signaling indicator and associated preferences indicate that quality of service notifications are not to be transmitted to the user device based on the signaling indicator and associated preferences indicating the quality of service notifications associated with a particular quality of service flow, quality of service notifications that relate to one or more quality of service flows mapped to a particular dedicated radio bearer (DRB), and quality of service notifications that relate to all quality of service flows mapped to a particular protocol data unit (PDU) session; and
based on determining that the user device is to receive the quality of service notification, providing, by the SMF module, the quality of service notification to the user device, wherein the quality of service notification is provided to the user device via a control protocol data unit in accordance with service data adaptation protocol (SDAP) in an instance in which the quality of service notification is associated with a priority level of a logical channel exceeding a priority level associated with a signal radio bearer 2 (SRB2) channel.
 
14. An apparatus comprising:
processing circuitry;
a session management function (SMF) module; and
at least one memory including computer program code, the at least one memory and the computer program code configured to, with the at least one processor, cause the SMF module at least to:
receive a signaling indicator from a user device, where in the signaling indicator comprises data associated with one or more preferences of the user device, wherein the signaling indicator is inferred using a reflective mapping;
receive a quality of service notification associated with the user device;
determine, based on the signaling indicator, whether to provide the quality of service notification to the user device wherein the signaling indicator is received via a non-access stratum message during a protocol data unit session, wherein determining whether to provide the quality of service indicator and quality of service notification are comprises:
determining whether the signaling indicator indicates that the quality of service notification should be provided to the user device based on the quality of service notification being associated with a change in one or more predefined quality of service parameters and a change in one or more predefined quality of service profiles; and
determining whether the signaling indicator and associated preferences indicate that quality of service notifications are not to be transmitted to the user device based on the signaling indicator and associated preferences indicating the quality of service notifications associated with a particular quality of service flow, quality of service notifications that relate to one or more quality of service flows mapped to a particular dedicated radio bearer (DRB), and quality of service notifications that relate to all quality of service flows mapped to a particular protocol data unit (PDU) session; and
based on determining that the user device is to receive the quality of service notification, providing the quality of service notification to the user device, wherein the quality of service notification is provided to the user device via a control protocol data unit in accordance with service data adaptation protocol (SDAP) in an instance in which the quality of service notification is associated with a priority level of a logical channel exceeding a priority level associated with a signal radio bearer 2 (SRB2) channel.
 
15. A system comprising:
an apparatus comprising a session management function (SMF) module;
a processor; and
a memory comprising computer-executable instructions that, when executed by the processor, cause the SMF module to perform the following operations:
receive a signaling indicator from a user device, wherein the signaling indicator comprises data associated with one or more preferences of the user device, wherein the signaling indicator is inferred using a reflective mapping;
receive a quality of service notification associated with the user device;
determine, based on the signaling indicator, whether to provide the quality of service notification to the user device, wherein the signaling indicator is received via a non-access stratum message during a protocol data unit session, wherein determining whether to provide the quality of service indicator and quality of service notification are comprises:
determining whether the signaling indicator indicates that the quality of service notification should be provided to the user device based on the quality of service notification being associated with a change in one or more predefined quality of service parameters and a change in one or more predefined quality of service profiles; and
determining whether the signaling indicator and associated preferences indicate that quality of service notifications are not to be transmitted to the user device based on the signaling indicator and associated preferences indicating the quality of service notifications associated with a particular quality of service flow, quality of service notifications that relate to one or more quality of service flows mapped to a particular dedicated radio bearer (DRB), and quality of service notifications that relate to all quality of service flows mapped to a particular protocol data unit (PDU) session; and
based on determining that the user device is to receive the quality of service notification, providing the quality of service notification to the user device, wherein the quality of service notification is provided to the user device via a control protocol data unit in accordance with service data adaptation protocol (SDAP) in an instance in which the quality of service notification is associated with a priority level of a logical channel exceeding a priority level associated with a signal radio bearer 2 (SRB2) channel.
