Binh,

A very high call drop rate is most probably the consequence of one of these two causes :

1. equipment failures (especially poor ABIS links, or faulty BSC/TC boards)

2. poor frequencly planning & poor cell planning (too much overlap, not enough downtilt)

Other problems, such as wrong parameters, low coverage, etc, can also cause problems, but usually not so critical.
