    I checked all of reason relating SD Congestion. So I cannot Find out it exactly. I think that It relates to BSC’s software or hardware. Could you give me the good way to correct it

    There are counters that indicate TCH drop reason in statistic (vendor specific):

    1.TA
    2.Quality
    3.Low Signal Strength
    4.Others( unknown)

    If TCH drop reason peg in counter Quality is high. Probably you can check on the IOI= interference on idle for the specific frequency.

    I can only help to provide formula for SDCCHBlockRate=(100.0*ATSDCMBS_s1/NATTSDPE_s1)
    where ATSDCMBS_s1|(1,8): Attempted SDCCH Seizures Meeting an SDCCH Blocked State, NATTSDPE_s1|(1,7): Number of Attempted SDCCH Seizures in a Period

    To French..

    SDCCH congestion could be as simply as low SDCCH dimensioning based on the number of radios you have on that sector…how is your SDCCH radio dimension done …also are those sectors having high SDCCH in BSC boarders or high traffic area?

    Please review dimensining part first and increase # of SDCCH assignment as necessary..try it out increasing one or two additional..and monitor.There are location upate parameters also which may need to be looked at. Good luck !!
    Thanks
