5G Core Network


  • 5G Core Network

    The training explains the challenges the 5GS faces from the huge variety of services it will carry, and presents the new network features that are the tools to enable the 5GS to satisfy the various service requirements in an optimal and cost-efficient way: Service Based Architecture approach with specialized NFs, Network Slicing, PDU Sessions with multiple PDU Session Anchors, hosting services closer to the user, traffic influencing from external AFs, and the 5G PCC model used to enforce service-specific handling rules. The course presents how the 5GC enables the different types of UEs to access services, discussing the 5G Registration, the PDU Session Establishment traffic cases, User Plane resources definitions and handling, UE mobility handling, and the three basic 5G use cases (eMBB – including Vo5G, MIoT/mMTC, URLLC). The presented features are used as a basis to discuss various deployment scenarios for evolving the EPS network into 5G.
