Abstract
The disclosed technology teaches alerting a network operator to deteriorated wireless network conditions with granularity and reduced false alerts, including receiving tracked performance indicators (KPIs) for multiple components of voice, data and messaging and accessing a mapping for combining the performance indicators into quality sub-indicators for individual users and into key quality indicators (KQI) for the individual users. This includes smoothing the current KQI measures of performance over time to reduce the impact of brief transitory events, accessing a weekly profile of KQIs, and comparing KQIs for a current time window to past KQIs for a corresponding time window for the individual users operating mobile devices in part of the cellular network that is a focus of interest. Based on the comparing, the disclosed technology includes generating alerts that report out-of-range current KQIs within the focus of interest that are persistently out-of-range for longer than a configurable time.
