Abstract
In a telecommunication network a subscriber connected to an originating local exchange requests activation of a supplementary service. The supplementary service establishes an end-to-end TC-dialogue with a corresponding supplementary service of a destination local exchange. The TC-dialogue terminates the request on an interfering telecommunication service in an intermediate node. For preventing service operation failure in case of interaction between the supplementary service and the interfering telecommunication service, a relay link is established between an incoming TC-dialogue and an outgoing TC-dialogue at the intermediate node to realize a chain of end-to-end TC-dialogues between the originating exchange and the destination exchange, while using a transparent relay functionality independent of utilizing TCAP based supplementary service ASEs as intermediate nodes. The handling and continuity of the chained dialogues is differentiated based on the effect of the interaction caused by the interfering telecommunication service.
