    Hi All,
    As per GSM rule LAC updation is done only in IDAL mode. So in dedicated mode if a mobile subsciber moves from one BSC to another then how this LAC updation works?

    The Location Update is performed on the SACCH, and it is called Location Update Follow-On.

    LU performed on idal mode only
    Case MS move to another LAC such as inter BSC or inter MSC HO. During on HO process new LAC/CI will update on VLR not inform HLR. After MS change state to idle mode the MS will initial LU process.

    Thanks Pix & Narchai,
    Could you also tell me that why default DMAX value is 255 as we knew that a mobile can survive upto max 32km means upto DMAX=64.

    Regards

    With this parameter you define the maximum distance between
    the BTS and the MS in call setup. The maximum distance is
    expressed as an access delay. Within the range of 0…62, one step
    correlates to a distance of 550 meters. If the access delay of the
    channel request message exceeds the given maximum, the call
    attempt is rejected. When the parameter is given a value from 63
    to 255, call attempts are never rejected
