    For incoming:
    -Congestion
    -radio problems (interference, HW faulty, bad parameters setting)
    -Wrong neighbors relations definitions (intra BSC, Inter BSC, Inter MSC)
    -Ghost HO (BCCH/BSIC conflict)
    -BSS problems (SW and/or HW, Transmission)

    For outgoing:
    -target cell congested
    -target cell is facing radio or BSS problems
    -target cell has same BCCH/BSIC with non defined nearest cell
    _wrong parameters setting in target cell
    etc…
