Claim of US Patent No. 10,251,178

6. A quality of experience (QoE) provisioning method of a user equipment (UE) measurement apparatus in a network, the method comprising:receiving, by the UE, a request for UE related information for QoE estimation from a policy and charging rules function (PCRF);
collecting, by the UE, the UE related information; and
transmitting, by the UE, the collected information to the PCRF,
wherein the UE related information is used in combination with network related information obtained from a network measurement apparatus to estimate a QoE of a data flow,
wherein the estimated QoE is used for a QoE adjustment,
wherein a QoE adjustment mechanism is identified based on a type of the data flow,
wherein a request for a first QoE adjustment is transmitted to an application function (AF), if information on the data flow is transmitted from the AF, the first QoE adjustment being performed by decreasing a transmission rate of the data flow,
wherein the request for a second QoE adjustment is transmitted to a transborder data flow (TDF), if information on the data flow is supported by the TDF, the request including a parameter related to the data flow for the second QoE adjustment, the second QoE adjustment being performed by dropping at least one of data packets of the data flow,
wherein the information on the data flow supported by the TDF is collected by using deep packet inspection, in the case that the information on the data flow transmitted from the AF is insufficient, and
wherein information including a transmission supported by the AF is transmitted from the AF to the PCRF, the request for the first QoE adjustment is transmitted to the AF, and the data flow with a decreased transmission rate is transmitted from the AF to the PCRF.
