    Dear All;

    Data drops have increased after second carrier activation. 1st carrier statistics are normal but 2nd carrier sites have high drops. Could you please help?

    Thanks.

    hi,

    check 2G & 3G neighbourhood (inc. and out.), CPICH power, trafic distribution… perhaps your second carrier is not taking much AMR traffic anyway, so the call drop% is not relevant.

    hi pix,

    all parameters and neighbours are same with 1st carrier. There is no problem with CS drops. only PS(hs/eul/r99) drops is high on 2nd carrier.

    Regards.

    hello vas,

    oh yes, it’s data drops only.

    Which Vendor it is?
    We had same problem in Ericsson.
    Ask core team do they use direct tunneling for SGSN?
    In our case Ericsson it was kind of bag- patch was loaded and drops became normal values-as 1st carrier.
