Reply To: SD Failure please help


Dear Optimizer /PIX

I am also facing the same issue of Ghost / Phantom RACH.
But after seeing the TA stats, i couldnt find any large TA on those hours where we have Many Location Update attempts, and then Immediate assignment failures.
So now how can i make sure that is it Phantom RACH.
And also what is the solution to minimize it. is it.
1. Optimize BSIC of the cell
2. Reduce TA (But in my case no excessive TA reported)

Kindly reply
