    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.

    regards

    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.
    I don’t have any idea, but i’m very interested in this issue too. Let’s hope someone will help 🙂

    regards

    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.

    Hello,

    We have the same issue after adding U900 cells on mixed mode with GSM900 as 2nd or 3rd or 4th carrier.

    Hs/Eul drop increase.
