As per spec, UE ID shall be reported when the message event configured by the Event Trigger Style 1 is set to “RRC Setup Complete" message (UE attach), or “Xn/NG Handover Request” or “F1 UE Context Setup Request” (Intra gNB Handover). In OAI RAN, Xn/NG Handover is not yet supported, and therefore not added as the trigger event in this commit. Additionally, as the Event Trigger Definition Format 1 is common for both "RRC Message" and "UE ID", E2 node will report the “RRC Setup Complete" message which the xApp will decode and print.
