Method and score management node for supporting service evaluation

摘要

A score management node receives network measurements related to at least one service event when the service is delivered to the user, and determines, in a first scoring module, a quality score Q reflecting the user's perception of quality of the delivered service and an associated significance S reflecting the user's perception of importance of the delivered service, based on the received network measurements. The determined quality score Q and associated significance S of each service event are modified in a succession of intermediate scoring modules, based on a predefined influence factor applied in each intermediate scoring module. The perception score P is further calculated in a concluding scoring module, based on the modified quality score and associated modified significance, wherein the calculated perception score P is made available for use in the service evaluation.

主权项

1. A method performed by a score management node, comprising a processor and a memory containing instructions executable by the processor, 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 method comprising the steps performed by the score management node:
receiving network measurements related to at least one service event when the service is delivered to the user, determining, in a first scoring module, a quality score Q reflecting the user's perception of quality of the delivered service and an associated significance S reflecting the user's perception of importance of the delivered service, based on the received network measurements, modifying, in a succession of intermediate scoring modules, the determined quality score Q and associated significance S of each service event based on a predefined influence factor applied in each intermediate scoring module, and calculating, in a concluding scoring module, the perception score P based on a modified quality score Qm and an associated modified significance Sm, wherein the calculated perception score P is made available for use in the service evaluation, wherein the score management node calculates a perception score PN for N service events of service delivery to the user asPN=∑n=1N⁢Qn⁢Sn∑n=1N⁢Sn where Qn is a modified quality score for the service event n and Sn is an associated modified significance for the service event n.
