VoLTE Formula

Hello,
What is the Huawei VoLTE traffic formula?
I guess it should be from L.Thrp.bits.DL.QCI.1
But that’s in bits…

L.Traffic.ActiveUser.DL.QCI.1 / L.Traffic.ActiveUser.UL.QCI.1 / L.ChMeas.PRB.DL.DrbUsed.Avg.VoIP / L.ChMeas.PRB.UL.DrbUsed.Avg.VoIP (These are for Voice Capacity)

L.E-RAB.SessionTime.HighPrecision.QCI1 / (ROP (min) x 60)
