5G promises to enable a wide variety of new wireless communications services and capabilities, ranging from high-speed, high-capacity broadband access to extremely reliable low-latency communications to machine-type communications on a massive scale. To deliver on these promises, everything about the wireless network must change, including the devices, the radio interface, the radio access network (RAN), and the core network.
This self-paced eLearning course offers a high-level technical overview of 5G Core Network – its principles, network architecture, the roles of various network functions and their connectivity, QoS framework, key network operations such as registration and PDU session establishment, network slicing, and MEC.

This course is designed for a broad audience of wireless network engineers. This includes those in network planning, engineering, operations, troubleshooting and support groups.

After completing this course, the student will be able to:
• List the key principles behind the evolving 5G core network
• Sketch the 5G core network and its connectivity to radio network as well as interworking with 4G EPC
• Describe the purpose behind Service Based Architecture (SBA)
• Describe MEC and how it can be used in 5G
• Describe network slicing and how it is used in 5G
• Step through the network operations of registration and PDU session establishment
• Describe QoS framework of 5G and compare it with 4G
