  • 4. Global Drive Test Report – Multan – W-35 1 EXECUTIVE SUMMARY This report is based on the Global Drive Test that was performed for Multan city in W35-2010 (25-08-2010 to 27-08-2010) under the scope of the Optimization Services Contract. Confidential Page 4 Alcatel-Lucent Pakistan Ltd
  • 5. Global Drive Test Report – Multan – W-35 2 DRIVE TEST RESULTS This section presents the Coverage & Quality of Mobilink network which has been measured during the global drive test. In addition to the Coverage & Quality plots, Network KPIs have also been included in the report. Alcatel has used TEMS Investigation Drive Test tool for this Air Interface Measurement and the KPIs have been processed using TEMS Reporter Generator. However, CSSR & CDR are calculated on real count basis so as to have more accurate KPIs. Confidential Page 5 Alcatel-Lucent Pakistan Ltd

  • 11. Global Drive Test Report – Multan – W-35 4.2.1 Bad Rx_Qual Patches in Plot #1 Case # Problem Recommendation 1 Call was HO from MUL0887C to remote cell OM8969B for some time which served with degraded quality & level; next HO to potential MUL7926C was ok; 0827_22 Log file 2 Call dragged on MUL3377B, better condition HO triggered late towards MUL3377C; 0827_01 Log file No severe issue observed in stats as well; except for an illogical HO at the time of DT probably due to some UL emergency cause; Change Source: MUL0887C Dest: OMR8969B HOMarginQual from -2 to 0 and will be monitored further in the next DT. To avoid intra cell HO at low levels instead of inter cell; Change Offset_HO_Margin_inner from 10 to 8 on MUL3377B; Change Source: MUL3377B Dest: MUL3377C HOMargin from 5 to 3 Confidential Page 11 Alcatel-Lucent Pakistan Ltd
