VoLTE drop call.
Hi All,
I have trouble with VoLTE drop call. Drop Reason is " radio connection with UE lost"- "QCI-IMS Signalling. Non-GBR. Priority 1". Could you please help me to solve this problem?
Thank you!

Re: VoLTE drop call.
If you have tools, check at what lvl of RSRP, RSRQ the drop is happening for particular UEs and you will understand is it really RF issue or some other. If its RF issue, then you can optimize RF or reduce SRVCC threshold.

Re: VoLTE drop call.
This error code is related to UE-IMS Signalling!
The first, you check the radio environment quality.
Then, check QoS for Volte in OSS, QCI index for Volte=1,5,9 ?
