What are the best RSRP/CQI level to have MOS better than 3.5?

RAN

Removing VoLTE from TDD gave good experience!

22

Yes, for mMIMO as well.
Good gain in Throughput.

23

Yes. :+1:
Now query is: what the highest RSRP level where VoLTE call should allow?
Is it -116/-118/-120?

24

-118 dBm? A2 threshold right?

25

No, B2.
I’m talking about SRVCC.
Not inter or Intra.
I have 4 layer.

  • L2500 - no volte
  • L2100 - -140
  • L1800 - 116
  • L900 -120

I am thinking above thresholds,
+ srvcc delay 30ms
+ time2trigger 1280ms

Any view ?

26

Is it B2 or A2 for VoLTE QCI1?

27

It is B2 SRVCC.

28

Ok, for L2100 it’s disabled.
Other settings look layer wise.

29

How about Layer Strategy setting like priority?
Which one is higher?
L1800, right?

30

Time to trigger B2?

31

B2 time to trigger 640 ms.

32

This:

  • L2500
  • L2100
  • L1800
  • L900

In Huawei we have some VQI KPI equivalent to MOS.
Will compare with VQI vs CQI.
And UL VQI vs Pusch SINR.
So @ankgitm, your valid point will have some idea based on these relationships.
But how to see RSRP vs VoLTE MOS.

34

Try to plot scatter graph if dt results there, i.e. SINR vs MOS.
Any correlation.
We can extract sample from Nemo logs for L1 having RSRP, SINR, etc.
MOS also there.

35

No DT… It’s corona time dear friend. :frowning:

36

Yes, tough time in India.

37

Any other way?
Or do anyone have this analysis?

38

MDT samples, but not sure MOS there or not.
