METHOD AND SCORE MANAGEMENT NODE FOR SUPPORTING SERVICE EVALUATION

A method and score management node for supporting service evaluation by obtaining a perception score P reflecting a user's experience of a service delivered by means of a telecommunication network. The score management node receives network measurements related to service events when the service is delivered to the user. For each received network measurement, the score management node determines a quality score Q reflecting the user's perception of quality of service delivery by applying a first function on the network measurement, and determines an associated significance S reflecting the user's perception of importance of service delivery by applying a second function on the network measurement. The first and second functions are dependent on network measurement type. The perception score P is then calculated based on the determined quality scores Q and associated significances S, wherein the calculated perception score P is made available for use in the service evaluation.
