METHOD AND SCORE MANAGEMENT NODE FOR SUPPORTING SERVICE EVALUATION BASED ON INDIVIDUALIZED USER PERCEPTION

摘要

A score management node identifies characteristics of a user, defines a user profile for the user which user profile comprises at least one predefined user group that matches the identified user characteristics, and sets user-specific model parameters based on the defined user profile wherein the user-specific model parameters are valid for the at least one user group in the user profile. When receiving network measurements related to service events when the service is delivered to the user, the score management node determines a quality score reflecting the user's perception of quality of service delivery and an associated significance reflecting the user's perception of importance of each service delivery, by applying the user-specific model parameters on each network measurement. The score management node then calculates the perception score based on the quality scores and associated significances, wherein the calculated perception score is made available for the service evaluation.
