Hi All,
How to improve CSFB preparation rate?
Vendor: Huawei

Already improved via CSFBflowfirst switch, smart Pre allocation and by increasing handover time to trig time.

Any new suggestions ?

How much you want to improve?
If you checked destination band?
Some times it may also cause degradation in CSFB SR.

I am talking about CSFB preparation phase, not execution.

Check RRC-connected-user congestion or not.
