# To balance congestion, consider cross effects between TCH/F and TCH/H when occupying a dynamic timeslot in the target:
# when balancing of TCH/F congestion would take up a dyn TS in the target, reducing TCH/H availability, the handover
# should not cause worse TCH/H congestion than in the source cell.

# bts 0 is full for TCH/F. Looking at TCH/F, by target_overbooked_after_ho==75% < current_overbooked_before_ho==100%, a
# congestion balancing to bts 1 would be performed. But the TCH/F on the target cell would occupy a dynamic timeslot.
# That would reduce the TCH/H free slots by two and cause TCH/H being overbooked by 50%. On the source cell, TCH/H is
# not congested. No handover is performed because 50% in the target is more congestion for TCH/H than 0% in the source
# cell.

# If there is no constraint on TCH/H in the target cell, the handover does take place.
