ARCD: a Solution for Root Cause Diagnosis in Mobile Networks

Abstract : With the growth of cellular networks, the supervision and troubleshooting tasks have become troublesome. We present a root cause diagnosis framework that identifies the major contributors (devices, services, user groups) to the network overall inefficiency, classifies these major contributors into groups and explores the dependencies between the different groups. Our solution provides telecommunication experts with a graph summing up the fault locations and their eventual dependencies, which helps them to trigger the adequate maintenance operation.
