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…

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.
