Course Contents

The 5G network architecture is a significant evolution from the 4G LTE EPC. Multi-Access Edge Computing (MEC) and Network Slicing are new abilities that enable the operator to improve the network to meet specific applications’ requirements.

During this course you will go through key operations such as power up and system acquisition, RRC connection setup, bearer setup with 5G NR, and DL and UL operations on 5G NR. This course covers key operations through call flows with details of major messages and their key parameters.

This course offers an insight into the signalling protocols applied in the 5G RAN. You will focus on the details of the NR interface signalling exchanged between the UE and the network, but the most important aspects of other NG-RAN interfaces are also covered. Most important network procedures, such as signalling connection establishment, registration, service request and handover are discussed and presented on signalling diagrams.

Target Audience

Network engineers, people involved in network design or systems performance, and operations related job functions who need to get an in-depth understanding of signalling procedures and Function.
