Method for measuring performance for QOS
A disclosure of this specification provides a method for performance measurement of SDF (service data flow), performed by SMF (Session Management Function), the device comprising: receiving a QoS (Quality of Service) rule from a SMF (Session Management Function); performing measurement of performance of a target QoS flow for the SDF, with a UPF (User Plane Function), wherein based on a reflective QoS being not used for the SDF, the QoS rule includes downlink QoS information on the target QoS flow, wherein the target QoS flow is a QoS flow used by the UE to receive a downlink packet for the SDF.
1. A method for performance measurement of SDF (service data flow), performed by SMF (Session Management Function), comprising:
determining performance measurement of a target QoS (Quality of Service) flow,
wherein downlink packet for the SDF is transmitted on the target QoS flow to a UE (user equipment);
including downlink QoS information on the target QoS flow in a QoS rule, based on a reflective QoS being not used for the SDF; and
transmitting the QoS rule to the UE.
2. The method of claim 1 , further comprising:
receiving PDU (protocol data unit) session establishment request message from the UE;
wherein the step of transmitting the QoS rule comprises transmitting PDU session establishment accept message including the QoS rule.
3. The method of claim 2 ,
wherein the PDU session establishment request message includes MA (multi-access) PDU session request indication.
4. The method of claim 1 ,
wherein based on the reflective QoS being used for the SDF, the method further comprises skipping the step of including downlink QoS information on the target QoS flow in QoS rule.
5. A method to measure performance of SDF (service data flow), performed by UE (user equipment), comprising:
receiving a QoS (Quality of Service) rule from a SMF (Session Management Function);
performing measurement of performance of a target QoS flow for the SDF, with a UPF (User Plane Function),
wherein based on a reflective QoS being not used for the SDF, the QoS rule includes downlink QoS information on the target QoS flow,
wherein the target QoS flow is a QoS flow used by the UE to receive a downlink packet for the SDF.
6. The method of claim 5 , further comprising:
transmitting a PDU (protocol data unit) session establishment request message to the SMF;
wherein the step of receiving the QoS rule comprises receiving the PDU session establishment accept message including the QoS rule.
7. The method of claim 5 ,
wherein the PDU session establishment request message includes a MA (multi-access) PDU session request indication.
8. The method of claim 5 ,
wherein based on the reflective QoS being used for the SDF, the QoS rule does not include downlink QoS information of the target QoS flow.
9. A device configured to perform performance measurement of SDF (service data flow), the device comprising:
a transceiver; and
a processor,
wherein the transceiver receives a QoS (Quality of Service) rule from a SMF (Session Management Function);
wherein the processor performs measurement of performance of a target QoS flow for the SDF, with a UPF (User Plane Function),
wherein based on a reflective QoS being not used for the SDF, the QoS rule includes downlink QoS information on the target QoS flow,
wherein the target QoS flow is a QoS flow used by the device to receive a downlink packet for the SDF.
