    Hello:

    Please would somebody help me? I’d like to know the usual time between the moment you press the “send” button and the time you hear the first ring in a GSM network, I read once that this time should be less than 6 secs in a Mobile to fix call and 12 between two mobile phones call, is this correct? I think there should be a difference if it is local or long distance.
    Thanks and regards

    hi Miguel
    our telecom nowadays we installed a news mobile network with a very long routing.At our first mobile-mbile call test it was about 23sec and fixedline-mobile 18 sec.
    Really it was very terrible,but fortunately we pushed eventually into superfast call only 2sec for mobile-mobile and 3sec for fixedline-mbile

    We use automated vehicle mounted equipment to measure call setup delay from the subscriber perspective. Our values are 6.5 MOC GSM-ISDN (internal) and 7.8 for MTC (ISDN->GSM).
    It can be longer if you use compression between different MSC

    One of the solution is hard reset.
    Just remove the DRUs of particular cell one by one and check after that.
    Reason:- Because the DRUs are running by software and possible that the software may be hang.
    when u remove & re-insert the DRU it will automatically “HARD RESET”. bcoz there is a small pin behind the DRU. So when u re-insert it will automatically hard re-set and start loading software from BSC.
    When u reset from front i.e “SOFT RESET”. The dru will b reset but not the Rx power it is radiating.
    So don’t worry. Just remove & re-insert the DRUs.

    -call setup delay is being reported through field measurements ie DT ?
    -through switch measurements ?
    -or its customer percieved ..delay being reported by subscribers ?
