Signaling in a telecommunication system

摘要

The invention addresses the transmission of TCAP messages of an SS7 network through an IP network. This transmission of signalling information from a first application part at a first telecommunication node towards a second application part at a second telecommunication node comprises: generating signalling information at the first application part, including addressing information associated with the second application part; passing the signalling information from the first application part to the TCAP; passing said signalling information from the TCAP to a first adaptation layer for translation therein of said addressing information into a destination IP address and port number, wherein said addressing information to be translated includes at least one of: global title and Destination Point Code; passing said signalling information and said destination IP address and port number to an IP part and transmitting the signalling information over an IP network to said destination IP address in one or more IP datagram; receiving the signalling information over the IP network in one or more IP datagram, the signalling information including an IP address and a port number, the IP address addressing the second telecommunication node; decapsulating the signalling information at a second adaptation layer identified by the port number; and routing the signalling information to the second peer application part.
