Module Objectives
At the end of this module the trainee should be able to: Describe the WCDMA measurement process of Optimizer Perform WCDMA measurements for RNCs Combine and visualise WCDMA adjacency and DSR (Detected Set
Reporting) KPI sets

WCDMA Adjacency Measurements
WCDMA Measurement process How can I start the measurements for RAS06? How can I combine the KPIs from different
measured days for RAS06?
5 Nokia Siemens Networks Presentation /PLe /20.4.2009For public use IPR applies
Measurement Process For RNC RU10, Optimizer gets the measurements from NetAct PM database For RNC RAS06, Optimizer uses MML commands to run measurements directly in RNC
Existing actual adjacencies and/or detected cells are measured

Starting the Measurement
Start measurements: Tools menu or Navigator popup menu Select the RNCs to be measured (RAS06 level)
from the Navigator from the Browser in the Start WCDMA Measurements dialog
The user needs RUN_RNC_MEASUREMENTS rights
8 Nokia Siemens Networks Presentation /PLe /20.4.2009For public use IPR applies
Start WCDMA Measurements (1/4)
Define a new name Typical measurement parameters are
1 - 5 days 1 - 4 times / day 30 min - 2 hours / measurement
Binary data is deleted by default from the RNC after successful retrieval to LinAs. After successful parsing binary data is also deleted from LinAs.
Also starting new measurement clears all old log files in RNC (not in LinAs).
Interferer search distance is used for mapping UARFCN/ scrambling code to cell-ID
Check the scope before starting
9 Nokia Siemens Networks Presentation /PLe /20.4.2009For public use IPR applies
Start WCDMA Measurements (2/4)
One measurement can last for several days
Measurement times can be different every day
After measurement ends give Optimizer approximately the same time to process the data than you have been measuring
Optimizer automatically combines the KPI sets of each day to a custom set with the name of the measurement
You may use measurement names like May_06_09"if your measurement lasts several days
10 Nokia Siemens Networks Presentation /PLe /20.4.2009For public use IPR applies
Start WCDMA Measurements (3/4)
The scope is automatically set if any RNCs are selected in Navigator or Browser before starting the dialog
Modifications allowed

Measurement Status
Tools->Network Statistics->View Measurement Status
13 Nokia Siemens Networks Presentation /PLe /20.4.2009For public use IPR applies
RNC Status
During the measurements RNC status shows the buffer size and the number of collected messages, the filled buffer size and the estimated time to fill the buffer
Tools->Network Statistics->RNC Status, select RNC and refresh
Can also be used to terminate monitoring Test measurement can be used to approximate the measurement time and buffer
limitations A short measurement can be used to estimates how long (under current traffic
conditions) one can run measurements
14 Nokia Siemens Networks Presentation /PLe /20.4.2009For public use IPR applies
Monitoring Measurements
Logs are parsed and KPIs imported automatically after the last measurement of a day
Parsed CSV files can be downloaded from the server for troubleshooting purposes
15 Nokia Siemens Networks Presentation /PLe /20.4.2009For public use IPR applies
Log Messages
Logs can be checked to see if there are any errors or warnings

WCDMA Adjacency/DSR KPIs
18 Nokia Siemens Networks Presentation /PLe /20.4.2009For public use IPR applies
WCDMA Adjacency KPI Facts
KPIs available only for measured RNCs Only one KPI set is imported for each day If measurement lasts several days Optimizer automatically combines the
sets of all days into a custom set with the same name as the measurement (e.g. "New Measurement")
KPI sets for each day and the combined custom set are available some time after the last measurement has stopped
Retrieval not possible since the data comes from RNC (not PM database) A custom KPI set == custom summarisation level for ADJG/ADJS/DSR A custom KPI set may contain ADJG, ADJS and DSR KPIs ADJG, ADJS and DSR KPIs from different measurement days
can also be manuallycombined into a new orexisting custom set
19 Nokia Siemens Networks Presentation /PLe /20.4.2009For public use IPR applies
Combine KPI Sets
Select an ADJG, ADJS or DSR KPI to view existing sets in Optimizer database
Give a new name or select an existing KPI set and expiration date and combine
Original sets for each day are still available after combining a custom set
Each KPI has to be combined separately. If one common set is wanted, reuse the KPI set name
20 Nokia Siemens Networks Presentation /PLe /20.4.2009For public use IPR applies
Visualisation of the Combined Sets
Refresh ADJS/ADJG/DSR KPI summarisation levels
Select the new level Visualise normally If Day is selected then
the visualisation dateis the date selectedfor all KPIs

WCDMA Adjacency KPIs on Map
Select the date of the measurements
Select a KPI to display for Adjacency Line
Show adjacencies for a cell KPI values can also be viewed

Summary WCDMA measurements are retrieved from Pm DB (RU10) or directly from
RNC (RAS06) WCDMA measurements for RAS06 can be defined in Optimizer
Number of measurement days Number of measurement times per day Duration of each measurement Start times of measurements for each day
Measurement status and RNC status can be monitored KPI sets are automatically imported into Optimizer database after each
day's measurements) KPI sets from different days are automatically combined into a custom KPI
set when the measurement lasts for more than one day Combination is needed to get more than just day level data After the measurements the KPIs are available for visualisation and
optimisation
