What you describe is quite a vague transaction, are there are many ways liabilities can be transferred. Furthermore, whenever liabilities are "transferred" there will (almost definitely) be payment of a premium as well. However what you describe certainly isn't a commutation.
My understanding is that a commutation always describes the action of a ceding insurer cancelling a particular reinsurance cover and therefore retaining all future liabilities.
Since the reinsurer is passing obligations in respect of these liabilities back to the cedant, the reinsurer will usually also pay some money in the form of a premium back to the ceding insurer.
