Technique for Performance Management in a Mobile Communications Network

摘要

A technique of generating statistics for a performance metric of a mobile communications network is presented. The performance metric depends on at least a first parameter and a second parameter, wherein the first and second parameters each can be categorized in two or more non-overlapping sets of parameter values. Different combinations of first and second parameter value sets are defined. A method implementation of the technique comprises receiving performance metric values, first parameter values and second parameter values. A particular performance metric value is associated with the first and second parameter values prevailing when the particular performance metric value was acquired. The method further comprises identifying groups of performance metric values for which the associated first and second parameter values match the first and second parameter value sets of an individual combination, and generating the performance metric statistic from the identified groups of performance metric values.

1. A method of generating statistics for a Key Performance Indicator, KPI, of a mobile communications network, the KPI having a dependency on at least a first parameter and a second parameter, wherein each of the first parameter and the second parameter is categorized in two or more non-overlapping sets of parameter values, and wherein different combinations of a first parameter value set and a second parameter value set are defined, the method being performed by one of a Network Management System, NMS, and a network node and comprising:
receiving KPI values, first parameter values and second parameter values, wherein a particular KPI value is associated with the first and second parameters values prevailing when the particular KPI value was acquired; identifying groups of KPI values for which the associated first and second parameter values match the first and second parameter value sets of an individual combination; and generating the KPI statistics from the identified groups of KPI values, wherein the KPI statistics are generated by processing the KPI values on a group-by-group basis.
