CSFB delay time in NEMO

I want to know where CSFB delay time shows in Nemo Outdoor 8.1.
I have seen many times in L3 msg but there is no result found.
Please suggest.

layer 3 doesnt show setup time. at lte end extended service request till rrc release is your CSFB Setup time.Most operators take from Extended service request tilll CM Service request or RRC Setup completed of 3G depending on customer requirement if it is LTE to 3G CSFB. its manual calculation.
