• In addition to default system reports, the user/client have the liberty to
create custom KPI reports that meet his/her needs.
• Operations related to reports (creation, viewing, modifying, and
maintaining reports) are under the Report Management function.

User-defined Reports Creation (Contd.)
• As mentioned earlier, PRS has limited storage capabilities for each timedimension (e.g., 31 days max for hourly data).
• Scheduling a report can ease your burden (have u ever forgot to extract
hourly data @ the end of month for an SLA report ?)
• PRS allows you to set a scheduled task for an existing report as required.
Then, the system generates reports on a scheduled basis.
• How to create a scheduled report?

Object Group Creation
• PRS allows for creation of groups of objects of same type
(cells, sites, BSCs/RNCs,..).
• Can be helpful in case u need to analyze performance per
area (add all objects on the area into 1 object group).

• Object Group Management involves:
 Create an object group (manually or template-based).
 Import an object group.
 Export an object group (ease of sharing!).
 Modify existing object groups.
HUAWEI TECHNOLOGIES CO., LTD.

Object Group Creation (Contd.)
• How to create an object group? There are 2 ways (either
manually or thru preparing & importing an .xlsx template).
• From the main menu (under MAE-Evaluation home page),
choose Report>Object Group Management.

Object Group Creation (Contd.)
• Manual creation can be tedious case many instances need to
be added to a group! PRS allows for easier creation of object
groups based on .xlsx templates.
• Following is a sample illustration of how to create a 2G GCELL
object group based on xlsx template.
• Repeat the same initial steps on the New Object Group
window as before (Click>New, then Set: Name, NE type,
Object type, description, Type). Afterwards, fill in the below
template with the desired object instances (i.e. 2G Cells).

Counters Activation
• PRS only extracts/aggregates data for system KPIs/counters that are
activated.
• In case you need to activate a system-KPI for use in PRS, you can do it
directly from within PRS or via the U2020.
• Inactivated system KPIs are displayed in gray (in the KPIs management
window).
• Below is an example activation of a BSC level counter (HR9725:Max subsys
CPU usage).
1. Tick “Show inactive KPIs”
2. Search for the inactive counter
(Name or ID)
3. select the system KPI to be activated
and click Activate/Deactivate.

Counters Activation
• Below are recommendations for counter activation:
 T7817:Maximum Ping Packet Loss Rate of Adjacent Node [3G]
 T7816:Average Ping Packet Loss Rate of Adjacent Node [3G]
 T7913:Maximum Transmit Rate at the IP Layer on Adjacent Node User Plane per
Interface Board (indication of max. 3G Iub TX rate/Throughput) [3G]
 T7914:Mean Transmit Rate at the IP Layer on Adjacent Node User Plane
(indication of avg. 3G Iub TX rate/Throughput) [3G]

AR9311:Average Number of Occupied PDCHs [2G]
 AR9406:Average Number of Sampled Occupied PDCHs (Overlaid Subcell) [2G]
Remark:
Last 2 counters can be used to calculate Busy PDCHs per 900/underlaid subcell
And, hence, PS traffic per band (since no raw counters are available):
PS traffic per 900/underlaid= [PS Data volume] *(1-[AR9406]/[AR9311])
PS traffic per 1800/overlaid= [PS Data volume] *( [AR9406]/[AR9311])
