GSM Network Optimization

Special statistical profiles are included in the Signaling Advisor for the

analysis of the radio resource element of the GSM Abis interface

signaling.

These profiles extract key information from, for example, measurement

result messages, and then present it to the user in a form which can aid

network optimization.

GPRS Statistics

Predefined GPRS statistics (for the GPRS Gb interface) aid

troubleshooting and trend analysis. The statistics are available graphically

and can be measured over time if required. The statistics currently

available are:

• Message / packet and cause / reject counts for all protocols

• SAPI distributions

• Higher layer protocol distributions

• Link utilization mean/max

• Packet length distribution

• Attach Time min/mean/max

• Session status (successful/unsuccessful) count

• PDP context activation Time min/ mean/max

• PDP context Deactivation time min/mean/max

• PDP context Duration MIN/MEAN/ MAX

• Uplink/downlink packet counts

• Uplink/downlink octet counts

Data Export

Statistics can be exported to a CSV (Comma Separated Value) file for

further analysis in another application (e.g., Spreadsheet or Data base).
