    HI DEAR
    PLS SPECIFY WHICH VENDOR U R USING? OVER ALL THE PROBLEM CAN BE OVERSHOOT, MISSING NEIGHBORS, INTERFERENCE, MISSING HO ON SIGNALLING CHANNELS, TX LINK STABILITY, HARDWARE FAULTS ON TRX, BTS,BSC OR EVEN MSC WISE.
    IN CASE OF CLARIFYING THE VENDOR, WE WILL BE ABLE TO GIVE U MORE EFFICIENT IDEAS AND SOLUTIONS

    Hi all,

    we see the same problem in Nokia BSS. The SDCCH Drop Rate rises if there are many location updates in the cell or when the traffic is low.

    Regards

    Hi,

    We are facing this problem, high ATIMASCA for LUP (in huge number) but some investigation it’s just a phenomenon called “Phantom RACH”.
