It seems that is not the best way to save in the structure the pointer
to the channel condition model because the underlying condition,
and later when we compare the new condition with the old one, we
are basically comparing the underlying object with itself, because
we saved the pointer to it in the structure.
Instead we should save the concrete values of LOS and O2I condition
in the 3gpp structure, and then once the ChannelCondition state changes,
we can compare these saved values against the new once.
This could not be done when the pointer was being changed because pointer
was pointing to the same object.
This fixes basically the condition in 3gpp whether th channel needs to be
updated when condition changes.
