Is anyone aware of Customer Satisfaction Index (CSI)?
What possible formula can it have?
It is not vendor standard formula, but customized one by the customer (such as NQI I worked previously for an operstor in Turkey).
I am building solution for C Level people, Including CSI for VOLTE, 5G.
I need to define/create some formulas (such as CSI=accessibilty (cssr) *retainability (volte erab drop%) for example.
Any previous/current experiences from your projects?
NQI is same as you mention (1-drop)*accessibility.
For LTE, NR mos, audio gap can be a included as part of combined formula.
NQI can be, audio gap is a formula by itself as for Ericsson for example, MOS needs tools (swiss qual…) for calculation and we are not using them.
I prefer created formulas or something like that.
If I would be a C level I would require CSI based on MDT processing and not based only on OSS counters.
Only MDT reflects coverage holes and problematic areas in deep indoor.
I agree with you.
MDT is Nokia specific tool.
My Solution based on AI and ML and network predictions (SAS AI/ML) should be according to existing data/KPIs/networks status (bottlenecks/events/loads…).
U can include call setup time and silent calls
