MOS NEMO vs PROBE (Huawei)

[optwcdma]

Hi Everyone,
I have a question. When we talk about the MOS, we usually use NEMO's MOS. How about PROBE'S MOS? MOS of PROBE could be accepted by Operators.
When driving test, I always see PROBE's MOS higher than NEMO's. Should I use PROBE's MOS for my report. Thank for any advise about it!
Best Regards,

I found some document about NEMO and PROBE. Two equipments use the same algorithm (PESQ Algorithm). I think difference of NEMO and PROBE is structure ( PROBE doesn't need sound card, NEMO need). So MOS value is difference too. NEMO is more accurate than PROBE or not?
BR,
