This course presents the signaling communication within 5G Core Network as specified in the current Rel-16 3GPP standards.

In order to provide the general context, the course briefly introduces the network organization, the roles of all the major 5G Network Functions (NFs), the basic 5G use cases (eMBB, mMTC and URLLC), the UE identities, and so on.

The course focuses on protocols and signaling procedures inside the 5G Core Network, between the UE and the Core Network and also between the 5G Radio Access Network and the 5G Core Network. The course describes the procedures used in the Standalone 5G Network deployments. The selected signaling procedures are presented on a message parameters level of details with some examples using traces from the 5G network.
