Hello All.
Can someone explain the cause codes for RRC Establishment and RRC Re-establishment in LTE?
Additionally, is there any document available to help analyze these codes for diagnosing a poor RRC Connection Success Rate?
UE Context Release Codes:
A UE triggers RRC re-establishment in response to failures such as radio link failure, handover failure, irrecoverable RLC errors, or reconfiguration failure.
Is there a way to analyze which cause code corresponds to the specific failures mentioned above (radio link failure, handover failure, RLC error, or reconfiguration failure)?
Please check the related counters. The provided picture indicates a failure due to congestion. If the issue is related to RRC rejection, consider increasing the T300 timer.
For the cause code, please analyze the UE trace.
