i encounter with strange problem.
my vendor in BSC and BTS is nokia.
one cell in my Nokia BSC use whole SDCCH reasorce with no reason.
it have 23 SDCCH(3 SDCCH/8)That 2 of them place on BCCH TRX(with CBCH On one of them)and 1 ofe them is on NonBCCH TRX.
my site is 2-2-2
i visit site and dont have any HW problem,even i exchange BB2F with other sector,but problem not solved.
i check very Parameter in cell,all of them set rational.
Periodic LU is 4 hourse in whole nework.
this site is not in LAC border.
when i disable IMSI detach/Attach in this cell the problem doesnot solve yet,it means that SDCCH reasorces doesnot occupy with IMSI detach/Attach Process or LU.
i have Congstion on SDCCH and SDCCH blocking in this cell and i have a few traffic in this cell.
can any body guide me to solve problem without visit site again?!
