Analyzing the 5G Core

Building on the foundation of 5G System Engineering, this course provides a detailed examination of the 5G Core Network. Key emphasis is placed on the Service Based network architecture, as well as the main network procedures that occur during a mobile’s typical interactivity with the 5G network. Analysis of the 5G Registration, PDU Session establishment, PDU Session usage, Policy Control, Mobility and Interworking will be provided as part of this process. In conclusion, the course will cover the key aspects of voice services across the 5G core, including discussion on EPS Fallback and VoNR.
