Systems and methods for network monitoring and testing using self-adaptive triggers based on KPI values

摘要

Embodiments are directed to systems and methods for network monitoring and testing using self-adaptive Key Performance Indicator to establish thresholds to trigger alarms in network monitoring. The present embodiments will be described in the context of calculating KPIs for call detail records (CDRs) and using the KPIs for network monitoring.

1. A method of determining a normal key performance indicator (KPI) value, comprising the steps of:
recording an initial set of a plurality of KPI values during a learning period; computing a normal KPI value based on the initial set of the plurality of KPI values at an end of the learning period; monitoring the plurality of KPI values; comparing one KPI value of the plurality of KPI values to a range of normal KPI values, wherein the one KPI value is indicative of a network performance issue; sending an alarm to one or more recipients based on determination of a deviation between the one KPI value to the range of KPI values and based on a first set of rules describing conditions for sending the alarm to the one or more recipients based on the deviation; and using one or more KPI values from the initial set of the plurality of KPI values and one or more new KPI values from the plurality of KPI values to update the normal KPI value based on a second set of rules describing conditions for:
updating the normal KPI value; anddetermining which of the one or more new KPI values should be used to update the normal KPI value and which of the one or more new KPI values should be excluded from updating the normal KPI;wherein:sending the alarm to the one or more recipients comprises sending the alarm over a packet-based network; andrepeating said monitoring, comparing, and sending using the updated normal KPI value.
