5G Call Flows (Session 1): How a 5G UE/Mobile performs Initial Access
One of the most complex area for beginners is to understand 5G Call Flows and Signaling procedures. 3GPP defines them but they are not easy to understand. So, in this video, I have explained the 5G Call Flows (NSA) in a simplified manner and I have also included the contents of some of the important messages to show what actually goes on between UE/Mobile and the 5G network during the 5G Initial Access or Network Entry procedure! Moreover, I have highlighted some of the important 5G KPIs in the end that will help the audience to correlate the 5G Call Flow & Signaling procedure with the 5G KPI itself. This is also one of a popular 5G Interview topic as well and many questions are asked from this Signaling Procedure.
