Anomaly correlation mechanism for analysis of handovers in a communication network
First Claim
1. A method, comprising:
- receiving, by a system comprising a processor, data representing a first time series of failures of outgoing handovers, wherein the outgoing handovers are outbound communication transfers from a source cell of a wireless access point device to target cells; and
in response to determining, by the system based on a first probability distribution corresponding the outgoing handovers, that the source cell and a target cell of the target cells comprise a first anomalous relation represented by a first defined condition with respect to a defined periodic variation in the failures of the outgoing handovers within a defined period, sending, by the system, a message, directed to a device, identifying the first anomalous relation to facilitate removal of the first anomalous cell relation, from a data store, identifying the target cell as a handover candidate.

Abstract
Optimizing neighbor cell relationships for improving handover performance by interpreting handover failures is presented herein. A method can include receiving data representing a time series of failures of outgoing handovers corresponding to a wireless access point device, and determining, based on a determined condition corresponding to a metric, that a source cell of the wireless access point device is associated with an anomalous cell relation corresponding to the time series of the failures of the outgoing handovers in response to quantifying the time series based on the metric. In various examples, the quantifying can include quantifying the time series with respect to: a volume of the failures during a period of time, an entropy calculated on a probability distribution of the failures by determined relations between the source cell and target cells, and/or an entropy calculated on a probability distribution of determined outgoing handover outcomes.
