5G (SA) RAN Signaling and Operations
- Course Length:
- 21 hours
Learn about the life of a 5G device and related operations in a 5G Standalone (SA) network such as network acquisition, Radio Resource Control connection setup, registration and data session setup from a RAN signaling perspective. Explore downlink and uplink data transfer using 5G new radio, as well as handover and idle mode operations. Discover these key operations through signaling flows and learn details relating to key signaling messages and their parameters. This training is created to be both practical and engaging with exercises using log messages from a commercially deployed 5G SA network.
This detailed technical course is intended for engineering, RAN performance, and operations related job functions who need to get an in-depth understanding of signaling procedures of SA NR with the 5GC deployment.
After completing this course, the student will be able to:
■ Step through the life of a 5G UE in SA (Option 2) deployment
■ Identify steps of preparing to monitor 5G cell and 5G network acquisition
■ Identify steps of RRC connection setup with the gNB
■ Identify key steps of registering and setting up PDU session in SA
■ Explore the role of beamforming in DL and UL traffic operations
■ Step through the handover and mobility operations
