Is RRCConnectionReestablishment implemented in the Core? I’m using Free5GC with OAI and currently I am testing the OAI UE resynchronization. I’m encountering an error on the UE which says that RRCSetup is being sent in response to RRCConnectionReestablishmentRequest causing the UE to not establish a connection to the Core. Im testing this by having the Core running, then I bring up the gNB. The UE is then started and everything works as expected. Then to test, I stop the gNB and bring it back up a few seconds later. The UE finds it but breaks down when it does not receive RRCConnectionReestablishment.
Hello Justin-Garey,
Based on 3GPP spec TS 38.401 Section 8.7, the procedure is only between UE and gNB, which is not part of free5GC implementation. You may check out more information about the OAI RAN to solve the issue.
Please let me know if you have any question.
