    Hi guys,

    Are you talking about these 2 indicators ?

    GSDNALUSUR SDCCH_assign_success_lu_rate
    GSDNASUR SDCCH_assign_success_rate

    The 2nd one takes into account all failures whatever the reason of SDCCH usage (NA, LU, SMS, DETACH, etc)

    Are you giving daily values, or busy hour values ? If daily, then it is normal to have a good LU success : during the night, the number of LU remains stable (periodic LU) and there is no congestion and clean frequencies.
    If there is a difference at busy hour, then it is weird.

    Now, it seems to me that you are comparing NSS indicators with BSS indicators. I can’t help you here : each system is computing indicators in its own way. Double check the formula and they way each NSS counter is triggered. You might be surprised…?

    Hi Pix
    The indicators are same as you mentioned.

    SDCCH_assign_success_rate(GSDNASUR)(%)
    SDCCH_assign_success_lu_rate(GSDNALUSUR)(%)

    the fact is that
    SDCCH_assign_fail(GSDNAFLN) and SDCCH_assign_fail_lu(GSDNALUFLN)
    are almost equal.
