Abstract
A QoS control method and a device are disclosed. In the method, a session management function SMF entity obtains service data flow SDF-level QoS control information; the SMF entity sends the SDF-level QoS control information to a terminal; and the terminal performs QoS control on an uplink data packet based on the SDF-level QoS control information, or deletes the SDF-level QoS control information. In the foregoing method embodiments, the terminal can perform the QoS control on the uplink data packet based on the SDF-level QoS control information.
Claims24
A quality of service (QoS) control method, comprising:
- obtaining, by a device, one or more service data flow (SDF)-level QoS rules from a session management function entity, wherein each SDF-level QoS rule corresponds to an SDF, and wherein each SDF-level QoS rule comprises:
- a QoS rule identifier, at least one SDF-level packet filter corresponding to the SDF, an SDF-level QoS rule precedence value corresponding to the SDF, and a QoS flow identifier;
- performing, by the device, matching between an uplink data packet and the at least one SDF-level packet filters in the one or more SDF-level QoS rules based on the SDF-level QoS rule precedence values until an appropriate SDF-level QoS rule is found, wherein one of the at least one SDF-level packet filters in the appropriate SDF-level QoS rule matches the uplink data packet successfully;
- and
- transmitting, by the device, the uplink data packet using a QoS flow corresponding to a QoS flow identifier in the appropriate SDF-level QoS rule.
2 more elements
A device, comprising:
- a memory storage comprising instructions;
- and
- one or more processors in communication with the memory, wherein the one or more processors execute the instructions to:
- obtain one or more service data flow (SDF)-level quality of service (QoS) rules from a session management function entity, wherein each SDF-level QoS rule corresponds to an SDF, and wherein each SDF-level QoS rule comprises:
- a QoS rule identifier, at least one SDF-level packet filter corresponding to the SDF, an SDF-level QoS rule precedence value corresponding to the SDF, and a QoS flow identifier;
- perform matching between an uplink data packet and the at least one SDF-level packet filters in the one or more SDF-level QoS rules based on the SDF-level QoS rule precedence values until an appropriate SDF-level QoS rule is found, wherein one of the at least one SDF-level packet filters in the appropriate SDF-level QoS rule matches the uplink data packet successfully;
- and
- transmit the uplink data packet using a QoS flow corresponding to a QoS flow identifier in the appropriate SDF-level QoS rule.
