5G SA and NSA Mobility KPI Engineering and Optimization

This course offers a comprehensive and technical deep dive into 5G mobility—from foundational measurements to complex multiconnectivity operations. Master the principles and procedures that ensure seamless user movement and reliable high-speed connections in both standalone (SA) and non-standalone (NSA) architectures. Instructor Rahul Kaundal outlines the essentials of mobility KPIs, radio measurements, and critical events that trigger handover. Along the way explore the complete mobility lifecycle, from idle mode cell selection and reselection to active mode handovers and more advanced capabilities such as carrier aggregation and dual connectivity. By the end of this course, you’ll be prepared to optimize network performance, troubleshoot complex mobility failures, and leverage advanced features to deliver a superior 5G experience.

Learning objectives
Define 5G mobility key performance indicators (KPIs) and their role in assessing network performance and user experience.
Differentiate between 5G deployment models (SA versus NSA) and spectrum bands (FR1 versus FR2), explaining their impact on network capabilities and mobility strategies.
Interpret 5G radio measurements (RSRP, RSRQ, and SINR), and analyze the A-series and B-series measurement events that govern handover decisions.
Analyze idle mode mobility procedures, including cell selection and reselection, and configure parameters like priority and sub-priority to control UE behavior.
Explain the fundamental principles of dual connectivity (DC) and carrier aggregation (CA), comparing their roles in enhancing capacity and reliability.
Map the key procedures for active mode mobility, including secondary cell (SCell) and secondary node (SN) addition, activation, and management in both FR1 and FR2.
Deconstruct the EN-DC protocol stack, differentiating between bearer types (MCG, SCG, and Split) and tracing the data flow through user plane switching and aggregation mechanisms.
Correlate network counters with mobility events to measure the success rate of procedures like SCell addition and troubleshoot performance issues.
