Do following steps (If you sure about MAIO Parameters): 1-Go to scan frequency part of TEMS Investigation and add your network BCCH frequencies in SCAN List, (Mark BSIC decode). 2-Find how many BCCH are in your location that have near signal level to the main BCCH signal. Then write related cells name (cells with Hopping in nonBCCH TRXs). 3-Investigate Antenna information of that cells and do suitable tilt control. Electrical Tilt is better than mechanical tilt for cell control (theoretical reason). High sites might control first. But you must be careful about missing some area coverage. I think interference controlling has more priority than level increasing. 4-Also you can increase level of dominant cell by Antenna height increase or antenna change to high gain if possible. 5-You can select good HSN Pair by referring to following link too:

if available i also need the book ..
