WHAT IS CSSR STAND FOR AND WHAT IS IT?28th April 2009 at 16:02 #54338kamazGuest
@ 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%.29th April 2009 at 21:09 #54339FleurivalGuest

Is there a way to convert PS Erlang to megaytes?17th August 2009 at 11:07 #54345WICOPGuest
I think that’s not good solution. Because Very many parametrs depending to result (Erlang to Mbytes). You need formula for PS traffic by kbit/s.
