Abstract
Methods and apparatus for identifying a source of quality degradation for a media call flowing in a first direction and a second direction between a mobile-originating user equipment (UE) and a mobile-terminating (MT) UE are presented. In an example method, a network node obtains a set of multiple rules specified respectively for multiple candidate sources of quality degradation for the media call in the first direction. These rules indicate whether a particular candidate source is an actual source of quality degradation based on values of certain key performance indicators (KPIs). The network node identifies, from among the multiple candidate sources of quality degradation, one or more sources of quality degradation by evaluating one or more rules from the set of multiple rules.
