Abstract:
A method in a telecommunication network, in which a subscriber connected to an originating local exchange node has requested activation of a supplementary service located in an application of said originating node, wherein said supplementary service uses a Transaction Capability Application Part TCAP and a corresponding Abstract Service Element ASE for establishing an end-to-end Transaction Capability TC-dialogue, having a transaction ID, with the corresponding supplementary service in an application of a destination local exchange node to which an addressed remote subscriber is connected, and said TC-dialogue terminates the request on an interfering telecommunication service located in an application of an intermediate node,the method for enabling a network operator to prevent service operation failure when there is an interaction between said end-to-end TCAP based supplementary service and said interfering telecommunication service, the method comprising: a) establishing a relay link between an incoming TC-dialogue and an outgoing TC-dialogue at the intermediate node for providing a chain of end-to-end TC-dialogues between the originating local exchange node and the destination local exchange node, while using a transparent relay functionality being independent of utilizing TCAP based supplementary service ASEs at intermediate nodes, b) differentiating handling and continuity of the chained dialogues based on the effect of the interaction caused by said interfering telecommunication service, wherein said transparent relay functionality communicates the TCAP based supplementary service ASE and said effect of the interaction between said incoming TC-dialogue, said interfering telecommunication service and said outgoing TC-dialogue, and encapsulating the service ASE in a new TC-relay ASE that is realized either as new operations within Intelligent Network Application Part INAP or as another TCAP based supplementary service having an own set of ASE data elements.
