I have mentioned all below para of SGSN only…
Detach Timer:It will enable right after MS ends the GPRS seassion..
But,only if ,always online state is not activated..
VLR PERIODIC CLEANING START TIME:
It mean on the mentioned time(here 4o’clock morning),VLR will remove the IMSI whose Detach time has exceded the timer limit..
Detach Sub storage time:While,SGSN will still store the data of sub till this time..
My question is which timer I need to change after all these changes have been made..?
Regards,
Kamal
