Course Details
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 , MEC, 4G Interworking and network slicing will be provided as part of this process.
