5G Protocol Training

5G Protocol/Classroom replay

Do you need to know what procedures are triggered in the 5G RAN and how? What messages are exchanged among the RAN and core nodes? And which protocols are used to implement them? This course provides an in-depth understanding of the various protocols and procedures in the 5G RAN. It looks into the overall 5GS and EPS architectures, the functionalities of each node, and the interfaces interconnecting them. It details how Quality of Service and the different levels of security are implemented in 5G RAN. Focus is given on the functions and services provided by various L3 signaling protocols,  AS and RRC, and the different L2 transport protocols, PDCP, RLC, and MAC. It provides a thorough discussion on the Attach procedure and the different types of mobility and dual-connectivity possibilities in 5G RAN.

Target audience:

This course is suitable for anyone who needs to have a detailed knowledge of signaling procedures in
5G RAN, like Service Design Engineer, Network Design Engineer, Service Engineer.
