1. A method, comprising: receiving, by a system comprising a processor, data representing a time series of failures of outgoing handovers corresponding to a wireless access point device, wherein the outgoing handovers are outbound communication transfers from a source cell of the wireless access point device to target cells; and in response to quantifying the time series of the failures of the outgoing handovers based on a metric, determining, by the system based on a determined condition corresponding to the metric, that the source cell is associated with an anomalous cell relation corresponding to the time series of the failures of the outgoing handovers, wherein the anomalous cell relation comprises the source cell and a target cell of the target cells.
