Hello, Pix!
Thank you very much for clear and detailed explanation 🙂 shame on me 🙂
I’m starting to implement recommended settings. I’ll share the result – maybe it will be useful for somebody one day 🙂
About KPI *TCH_blocking_rate* – unfortunately we can’t just choose which formula to use…
We received from Moscow HQ new QoS standard and there was the next unambiguous formula:
TCH_Blocking_Rate(%) = 100 * (MC812 + MC541A + MC551 + MC561) / (MC812 + MC541A + MC551 + MC561 + MC15A + MC15B+ MC703)
Before we use this one:
TCH_Blocking_Rate (%) = 100.0*( MC812) / ( MC140A-( MC142E+ MC142F))
So now for us HO_congestion impacts TCH_blocking_rate (Most important KPI!!!) very much :((((
That’s why we’re now fighting windmills 🙁
Once more – many many thanks to you !
