Mobility and state management are at the heart of delivering seamless connectivity in 5G networks. This short, single-module course provides a technical overview of how the 5G Next Generation Radio Access Network (NG-RAN) manages UE mobility and RRC state transitions through signalling interactions.

In just three hours, you'll explore how devices move between key RRC states - RRC_IDLE, RRC_INACTIVE, and RRC_CONNECTED - and how signalling flows coordinate these transitions between the UE, gNBs, and core network functions such as the AMF, SMF, and UPF.

The course covers a range of mobility procedures, including intra- and inter-gNB handovers, with a focus on signalling, context management, and data forwarding. You'll also learn how dual connectivity is managed, including the addition and release of secondary nodes.

Designed for technical professionals who need a solid introduction to how 5G NG-RAN handles mobility and signalling, this course equips you with the essential knowledge required to understand and troubleshoot mobility-related behaviour in live 5G networks.
