Overview
Anova Data provides industry-standard key performance indicators (KPIs) and value-add aggregate VoLTE KPIs to
measure network activity and enable you to isolate issues within your network.
Using the information provided by the KPIs, you can perform actions including the following:
• proactively managing network services
• troubleshooting issues in real-time
• understanding the root causes of customer issues. .
Using KPIs for Network Quality Monitoring
When using KPIs to monitor network quality, you can evaluate the absolute value of the KPIs and compare the
results against other networks or with reference values. You can also use the KPIs to evaluate network usage trends
and the changes of the KPIs.
The value of a KPI can change for several reasons, including the following:
• Changes in the network configuration.
Typically, changes in the network configuration are indicated by a sudden change in the KPI value. These
sudden changes may be caused by:
• Network node faults which affect the surrounding areas
• New nodes integrated into the network
• Parameter changes (including the activation of new features)
Occasionally, the variation in KPI values can be more gradual, for example, when the network change is
related to a progressive rollout activities.

• Changes in the local traffic level
In most cases, the increase in the local traffic level is gradual and produces a gradual effect on the KPIs. The
KPI trend, in this case, is usually visible in weekly or monthly observation periods.
However when the load exceeds some thresholds the effect could produce a sudden degradation of the KPIs
during the most loaded hours of the day, alternated with more stable periods.
Special events, such as stadium events, public celebrations, public holidays, etc, can also generate peaks of
traffic.
• Changes in user behavior
User behavior can differ or change under the following conditions:
• During the work week and on the weekends.
• As a result of the introduction of new services or new applications/UEs.
• New usage offering by carriers.
• Environmental changes, such as the weather..
