In the sequence diagram, you have the option to filter directly by specific network procedures, allowing you to focus on analysis. All procedures are defined using 3GPP definitions.
Below, you'll find the list and details of each procedure per protocol. These tables can be used as a reference to understand the procedures list included with the sequence diagram.
