A method for enabling a combinational service in a communication network in which a plurality of terminals can operate, includes: establishing a first plurality of connections toward the plurality of terminals based on first terminal identifiers, providing a management entity with the first identifiers; providing the management entity with second identifiers of selected terminals included in at least part of said plurality; associating the first identifiers and the second identifiers with the combinational service; and establishing, by means of the management entity, a second plurality of connections toward said selected terminals by employing the second identifiers.
