As 5G networks mature, a solid grasp of the procedures that govern how devices and network functions interact is essential for professionals working in planning, operations, or optimisation. This short course offers a technical overview of the core signalling and operational procedures in 5G Standalone (SA) networks.

In just three hours, you'll explore how 5G procedures have evolved - from initial deployments that relied on LTE signalling to fully native 5G implementations across both the core and radio access network. The course covers the step-by-step processes involved in device registration, network function discovery, and session establishment and modification.

You'll also gain insight into mobility management procedures, including how 5G handles transitions between different UE states - idle, connected, and inactive - and how it manages tasks like cell selection, registration updates, service requests, and handovers. The role of the Radio Resource Control (RRC) protocol in managing radio connections, reporting measurements, and supporting dual connectivity scenarios is also explained.

This course is designed to provide technical professionals with a foundational understanding of how 5G devices and networks interact through signalling and procedure flows, forming the basis for reliable service delivery in real-world deployments.
