Information Feedback
If the CSSR is too low, send the data described in the following table to the WCDMA&GSM Network Performance Research Department. SN
Information
Remarks
Purpose
1
Software version
Software versions of the BSC and BTS
Check whether the software version is defective.
2
Data configuration table
Configuration files of the BSC, in *.dat format
Check the network optimization parameters and power configuration.
3
Alarm information
Alarm information related to hardware, clock, and transmission (self-check)
Check whether such alarms exist in the faulty cell. Such alarms should be cleared.
4
Traffic measurement
Observe the traffic measurement result and check for congestion or interference problems.
5
Signaling
RSL signaling tracing of fault occurrence time in the faulty cell
Search for the cause of call setup failure.
6
Drive test data
*.log (*.CELL) files or *.ant files
Observe the drive test data and check for interference or coverage problems
7
Network planning data
Engineering parameter tables and emaps
Network planning data facilitates the checking of the geographical information by the NASTAR tool.

Optimization Report
The optimization report provides the optimization projects described in this manual and implemented on site. The report also provides the optimization measures, which are not described in this manual but implemented on site.
The optimization report serves as a reference for future network planning.
The operations described in items 5 and 6 in the preceding table should be performed simultaneously. That is, when performing drive tests, you must trace the RSL signaling of the corresponding cell. Before the drive tests, you must also synchronize the PC time used for drive tests with the BSC time.
