VoLTE Formula

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

Admin note: this post was updated with image below.

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)

Can anyone please just share the most important KPIs names regarding VoLTE?

VoLTE attempts, success rate, drops.

Hi All.

What is the formula for VoLTE Retransmission?

Or in other words: How can we see the retransmission QCI wise?

Vendor is Huawei (PRS formula).

These counters are available:

How can we see PRS Formulas?

Go to KPI Management.

Select 4GBTS.

And on top right side there is a search window.

But actually I have a question: Does we have retransmissions in VoLTE mode? I mean during Call?

Because retransmission mode should be in data mode, because once call is established either it will be dropped or re-established.

I would like a clarification on it.

For VoLTE there are no RLC retransmissions, just MAC HARQ retransmissions.
