2 g and 3g kpi improvement by parameter optimization (nsn, ericsson, huawei) ...Jean de la Sagesse
The document discusses key performance indicators (KPIs) for 2G and 3G networks and how top telecom vendors like Ericsson, Huawei, and NSN optimize parameters to improve these KPIs. It outlines techniques for reducing TCH blocking, SD blocking, TCH drop, HOSR, TASR, SD drop, and improving paging success rate through actions like changing configuration parameters, enabling features, addressing hardware issues, and optimizing cells physically. The optimization of these parameters can help maintain balance between network throughput, capacity and radio quality while ensuring a seamless transition between 2G and 3G.
Mohammad Waqas Khan has over 5 years of experience as a 2G, 3G, and LTE RF engineer with ZTE in Pakistan, where he has led rollout projects and optimized networks through drive testing, parameter tuning, and troubleshooting issues.
