Understanding TC_6_1_1_1

TC_6_1_1_1 is the case everyone runs first: RRC connection establishment followed by initial registration. It is a good teaching case because it exercises PHY, MAC, RLC, PDCP, RRC, and NAS in one 15-second window.

Test purpose

Verify that the UE, on receiving a valid RRCSetup in response to an RRCSetupRequest with establishmentCause set for mobile-originated signalling, transmits a correctly formed RRCSetupComplete carrying an initial Registration Request, and completes registration.

Preamble

• Cell configured per the reference conditions for the band under test.
• UE in state 1 (switched off), USIM inserted with test credentials.
• Security context absent; no valid 5G-GUTI stored.

Expected sequence

1  UE   -> SS : PRACH preamble
2  SS   -> UE : Random Access Response
3  UE   -> SS : RRCSetupRequest (establishmentCause=mo-Signalling)
4  SS   -> UE : RRCSetup
5  UE   -> SS : RRCSetupComplete { Registration Request (initial) }
6  SS   -> UE : Authentication Request
7  UE   -> SS : Authentication Response
8  SS   -> UE : Security Mode Command
9  UE   -> SS : Security Mode Complete
10 SS   -> UE : Registration Accept (5G-GUTI assigned)
11 UE   -> SS : Registration Complete
   verdict: pass

The three common failures

aeon exec run --case TC_6_1_1_1 --build rc3 --follow

noteThis case takes about 14 seconds on a healthy lane. If it takes 45, you have a timer expiry and a retry, not a slow lane.
