2G Optimization Progress Report Presented by: Degdag Abderrahmane

• Introduction • Low throughput • Traffic balancing UL/OL

The objective of this report is to track the progress of 2G rollout worst cell During the previous weeks, many problematic and lowperformance cells were monitored and investigate. The problematic cells were extracted on weekly basis, analysed and then the necessary actions were taken, which in turn improved the statistical performance , as can be seen below

Low throughput : After the Upgrade and the activate of the Concentric cell feature, Throughput decrease It recommended to change: PS Load Sharing in Concentric Cell from NO to Either Overlaid Subcell or Underlaid Subcell

•Traffic balancing UL/OL

Because the Overlaid is suffer from high drop It recommended to move the traffic to Underlaid By changing these parameters UtoO HO Received Level Threshold from 25 to 38 OtoU HO Received Level Threshold from 20 to 25
