Try to get emil trace and check (RRCConReconfig)keychangeindicator = true ? RL50 have the new Intra eNB HO (LTE511) make security config HO problem if you find all Intra eNB HO failure with key change indicator = True in RRCConReconfig and no RRCConReconf. complete reply back from UE. You can reset for solve this issue.

Hi Kentck86
RSI collision can cause of this issue with but try to related with RACH SR degradation with Intra eNB HO if the same date therefore cause of RSI but my opinion I think cause of security key problem from LTE511 feature and if RSI collision it should problem of X2 and S1 HO as well.

Hi Jukreew,
I wasnt sure this feature is activated in my network or not. Any idea how can i check if its activated. As if its activated, this shall be causing all sites in the network having the intraEnodeB HO failure issue?
thank you

Hi Jukreew,
Is there any other method to check the said message besides from Emil Log? And i wonder why it only happens to certain site if this is default feature which should applied to all RL50 sites.
thank you

Try to reset a problem site and mornitoring it. if you work with nokia internal you can ref.
Change note ID
CN-id: LN50_113
Summary of the original problem: In Intra eNB HO command the keyChangeIndicator was set to “TRUE” causing Intra eNB HO failure (keyChangeIndicator should be set “TRUE” only for Intra Cell HO)
How end user/operator could detect the problem: Increased Intra eNB HO failure rate
