A scoring node arranged to estimate a user's Quality of Experience, QoE, when a service is delivered in a media stream to the user by a communication network, wherein the scoring node is configured to:

• extract quality-related parameters pertaining to the service delivery,
• obtain a set of quality models configured to estimate service quality,
• determine an individual opinion score for each of the quality models in the set by applying each respective quality model in the set on the extracted quality-related parameters, and
• determine an aggregated opinion score as a weighted average of the individual opinion scores, wherein the aggregated opinion score can be used as an estimation of the user's quality of experience for the service delivery.

A scoring node arranged to estimate a user's Quality of Experience, QoE, when a service is delivered in a media stream to the user by means of a communication network, the scoring node comprising:

• a processor and a memory, the memory comprising instructions executable by the processor and causes the processor to be operable to:
