Fault management is a crucial part of cellular network management systems. The status of the base
stations is usually monitored by well-defined key performance indicators (KPIs). The approaches for
cell degradation detection are based on either intra-cell or inter-cell analysis of the KPIs. In intra-cell
analysis, KPI profiles are built based on their local history data whereas in inter-cell analysis, KPIs of
one cell are compared with the corresponding KPIs of the other cells. In this work, we argue in favor
of the inter-cell approach and apply a degradation detection method that is able to detect a sleeping
cell that could be difficult to observe using traditional intra-cell methods. We demonstrate its use for
detecting emulated degradations among performance data recorded from a live LTE network. The
method can be integrated in current systems because it can operate using existing KPIs without any
major modification to the network infrastructure.

Anomaly Detection Algorithms for the Sleeping Cell Detection in LTE Networks
Chernov, Sergey; Cochez, Michael; Ristaniemi, Tapani (IEEE, 2015)The Sleeping Cell problem is a particular type of cell degradation in Long-Term Evolution (LTE) networks. In practice such cell outage leads to the lack of network service and sometimes it can be revealed only after ... -
