A method and a score management node for supporting service evaluation by obtaining a perception score reflecting a user's experience of one or more services delivered by a telecommunication network. The score management node receives a network measurement related to a current service event of service delivery to the user within a predefined time length from a previous service event, and determines a correlation level reflecting the user's perception of the current service event as correlated with the previous service event. A quality score is determined for the current service event, reflecting the user's perception of quality of service delivery and an associated significance reflecting the user's perception of importance of service delivery, based on the network measurement and the correlation level. The perception score is then calculated for the current service event as the quality score weighted by the associated significance and is made available for the service evaluation.

Method and score management node for supporting service evaluation based on correlated service events

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.
