    Hi, all.
    Sometimes it’s possible to get very high SDCCH drop ( up to 90% ) due to faulty mobile uncapable to complete periodical location update…

    Hi, Pix.

    I know for 2 times Siemens 25C and one Ericsson 28T.
    Very archaic mobiles.

    Usualy we fight with gateways ( especially illegals ).

    We have a problem with HIGH SDCCH drops on our network. It was usually 1.14%, but now it is around 2%. What should the SDCCH drops be ideally?

    Hello Patrick,

    Ideally… 0%…

    Typically, in urban area, a target KPI around 1% should be achieved.
    Basically, your SDCCH should be a little less than your TCH drop rate.

    I think SD drop on A interface is not calculated in the SD Drop formula.

    HI JB
    If SD Drop A inf is not calculated in SDR formula, how could you discover this fault when you get KPI report?
