CALL ROUTING BETWEEN A CIRCUIT SWITCHED AND A PACKET SWITCHED NETWORK

摘要

The invention relates to a method of setting up a connection between a first point within a circuit switched network and a second point within a packet switched network, wherein data is routed in the circuit switched network using signalling information and data is routed in the packet switched network using data network addresses. A translation table containing signalling information for a set of unique connections within the circuit switched network and respective data network addresses in the packet switched network is provided. For a connection initiated from said first point to said second point using signalling information, the signalling information is converted to a data network address using said translation table, and for a connection initiated from the second point to the first point using a data network address, the data network address is converted into signalling information using the translation table. The invention relates also to a telecommunication system and a signalling server for the same purpose.
