I am an RF Optimization Engineer, we are currently having too many network busy responses when calls are placed.
What do you think is responsible for this?
we recently re dimensioned our network to have one channel in each TRX to have SDCCH.
we have cells which have an SDCCH traffic of up to 30 Erl.
If it is due to congestion in the SDCCH, what do you think can be done to remedy this situation?
