    Normally SDCCH MHT is short it is from 2 to 4 s if it is more than this it means there is problem .
    1- Check do if there are a lot of SMS because normally SMS take more time than call setup.
    2-Check SDCCH drop rate it is high .
    3-Check if you have a lot of location update because also this one is also take more time .
    4- did you activate Authentication and ciphering normally this increase the time.
    last one is may be there is problem in MS makes a lot of IMSI attach and Detach.
