US Patent:

20180167855, Jun 14, 2018

Filed:

Feb 9, 2018

Appl. No.:

15/893563

Inventors:

- Atlanta GA, US
Zhi Cui - Sugar Hill GA, US
Duc Phan - Renton WA, US
Marcus Wright - Edmonds WA, US
Qinggang Zhou - Marietta GA, US

International Classification:

H04W 36/00
H04W 24/02

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.
