Claim 17:
18. A processing device comprising:
one or more processors and memory storing instructions that, when executed, cause the one or more processors to
responsive to a requirement to test an Over-the-Top (OTT) content provider by one of a user, a mobile network operator, an Internet service provider, and a content delivery provider, perform a first Quality of Experience (QoE) measurement from a first content source to obtain a QoE measurement from a second content source that is the OTT content provider, wherein the first QoE measurement includes one or more of download time from the first content source, connection time to the first content source, number of stalls and their duration from the first content source, throughput from the first content source, and waiting time, wherein the second content source is different from the first content source, and wherein the second content source has user policies prohibiting repeated requests for the QoE measurements from the user device,
determine a QoE adjustment factor based on a predictive model, wherein the QoE adjustment factor includes values to adjust the first QoE measurement to accurately substitute for the QoE measurement from the second content source that is the OTT content provider, wherein the values of the QoE adjustment factor are different values for different time intervals and are monitored and adjusted over time,
adjust the first QoE measurement using the QoE adjustment factor to obtain a second QoE measurement, the second QoE measurement reflects a QoE estimate from the second content source based on the first QoE measurement from the first content source, thereby complying with the user policies of the second content source, and
provide a graphical representation of the test with the second QoE measurement as the QoE estimate instead of performing the QoE measurement from the second content source.
