Benchmark OverviewBenchmark Overview
The France Telecom (FT) and Network Technology Service
(NTS) request the function of KPI benchmarking. 1 The requirements for KPI benchmarking of the BYG swapping project in France SFR are
as follows:
(1) The cluster-level KPIs instead of cell-level KPIs before and after the network swapping need
to be compared. The cluster-level KPIs after the network swapping must not be worse than
those before the network swapping.
(2) Generally, the average KPI values one to two weeks before the network swapping are
regarded as the benchmark values.
2 The NTS requests that the KPIs before and after the network optimization be compared.
3 It is requested that the benchmark values be calculated on the basis of history
performance data for monitoring network performance.
Copyright © 2009 Huawei Technologies Co., Ltd. All rights reserved. Page 50
Benchmark DefinitionBenchmark Definition Fixed benchmark
In a fixed benchmark rule, the benchmark value is fixed.
Fixed benchmark rules are classified into fixed benchmark rules (system)
and fixed benchmark rules (imported). The difference between the two
types of fixed benchmark rules lies in data sources of the benchmark
values. The benchmark values of fixed benchmark rules (system) are
from the internal PRS system, and the benchmark values of fixed
benchmark rules (imported) are from external data sources.
Floating benchmark
In a floating benchmark rule, the benchmark value is variable. The
benchmark value of a floating benchmark rule is obtained by adjusting
the average value based on the internal history data in the PRS.

3DBH is short for 3-Day Bush Hour.
Telenor requests the 3DBH for analyzing the network performance.
3DBH is a type of weekly busy hour. The 3DBH is calculated as follows:
(1) Calculate the busy hours of each day within a week. Then, you can obtain seven
busy hour data records about each object.
(2) Determine top 3 daily busy hours according to the obtained busy hour data
records.
(3) Calculate the average value of top 3 daily busy hour values for each KPI. Then,
one average value is calculated for each object. The calculated average value is the
3DBH data.
