Course overview

The 5G Core is a cloud-native, service-based system that behaves very differently from the EPC. This program covers the architecture in depth — AMF, SMF, UPF, PCF, UDM, AUSF, NRF, NSSF, NEF — and walks through the procedures engineers must understand to design, integrate and troubleshoot it.

Labs use an open-source 5G Core so participants can observe registration, PDU session establishment, QoS flows and slicing behaviour directly in packet captures.

Who should attend

  • Core network engineers and architects
  • Integration and test engineers
  • NOC and operations engineers moving to 5G SA
  • Solution architects for enterprise and private 5G

Prerequisites

  • Understanding of EPC or IP networking fundamentals
  • Basic Linux familiarity is helpful for labs

Learning objectives

  1. 1Describe the 5G Core service-based architecture and each network function's role
  2. 2Trace registration, PDU session, handover and service request procedures
  3. 3Explain QoS flows, policy control and charging in 5GC
  4. 4Design network slices using S-NSSAI, NSSF and slice-aware NFs
  5. 5Explain EPC–5GC interworking and migration options

Frequently asked questions

Labs are built on Open5GS with UERANSIM as the RAN/UE simulator. Lab content is adapted to the delivery format.

Live online programs are delivered in real time by an instructor over video with shared labs and interactive Q&A. Classroom programs are delivered face to face in Dubai or other GCC locations, with the instructor and lab environment in the room. Both use the same curricula and instructors.

Programs are built on 3GPP, O-RAN and industry standards and are vendor-agnostic by default. Corporate deliveries can include vendor-specific parameter mapping and scenarios where required.

Participants who complete a program receive a Teleriu certificate of completion. Teleriu programs are professional technical training and are not affiliated with any certification body unless explicitly stated.
