Classification of KPI Measurement
• The quality of network performance is mainly evaluated by KPI (Key Performance
Index)
› Drive Test KPI/ Stationary Test: Some KPIs should be attained by drive test, such as
such as coverage KPI and latency KPI, measurement results are coming from driver test tools.
› Performance Measurement KPI: Most of KPIs are attained by this approach, such as
RRC success Rate, HHO success rate, eg, these KPIs are coming from eNodeB
performance statistic.
