DEVICE AND METHOD FOR CONTROLLING QOS Russian patent published in 2021 - IPC H04W48/18 

FIELD: wireless communication.

SUBSTANCE: invention relates to wireless communication. Said technical result is achieved in that the object of the SMF session control function receives control information though the data flow of the QoS SDF-level service; the SMF object sends control information of the Qos SDF-level to the terminal device; and the terminal device performs QoS control of the data package of upward communication flow based on the control information of the QoS SDF-level or removes the control information of the QoS SDF-level. The terminal device can perform Qos control of the data package of upward communication flow based on the control information of QoS SDF-level.

EFFECT: ensuring correct QoS rule for transmitting a packet of an upward communication flow in order to prevent the packets of an upward communication flow being dropped on the network side.
