METHOD AND APPARATUS FOR AUTOMATICALLY DETERMINING CAUSES OF SERVICE QUALITY DEGRADATION

摘要

Causes of service quality degradation in a communication network are determined for automated root cause analysis by identifying (301) occurrence of degradation in service quality within a user session; identifying (303) an underperforming resource of the communication network during occurrence of said identified degradation in service quality;in response to determining that the underperforming resource has at least one dependant resource, identifying (305) any underperforming dependant resources during occurrence of said identified degradation in service quality; outputting (509) a plurality of causes of the service quality degradation including the identity of each of the identified underperforming resources.
