Hi all,
@ risa: it’s an ALU Formula, they dont have the same approach.
@ Jose: if you have a Direct Retry in your Network you will have this behaviour in the TCH part. It’s simple, when we perform a TCH Request in one cell (cell1) but due to congestion we perform a Direct Retry to another cell (cell2), in addition, we have a TCH Att in cell1 and a TCH Succ in cell2 (not in cell1). So TCH Success in cell2 will be over than TCH Att in the same cell (cell2) ==> TCH Success Rate over than 100%.
