Hi,
In H// RAN QCI 9 and QCI 5 are always established and deactivated together for VoLTE provisioned subscribers for any Internet/data activity/inactivity. So QCI 5 attempts are almost same as QCI 9 attempts for a VoLTE subscriber. It seems to be unnecessary as we need QCI 5 only during VoLTE session. The benefit could be fast VoLTE setup if UE is already in RRC connected state due to data activity. I want to know if it is as per 3GPP standard? If yes then I would appreciate the reference document number.
Thanks.
