Abstract:
A method for interworking between a first data communication network and a second data communication network, said first data communication network comprising a first Signalling System 7 based data communication protocol, and said second data communication network comprising a second data communication protocol, said method comprising the steps of:dividing a set of second level functions of a signalling link of a second Signalling System 7 based data communication protocol between two terminals of the second data communication network to form respective first and second predetermined sets of functions; processing data in accordance with the first predetermined set of functions for supporting a user of said second Signalling System 7 based data communication protocol within said second data communication network; adapting said processed data to said second data communication protocol such that said processed data may be routed by said second data communication network; adapting said routed data to said second Signalling System 7 based data communication protocol; and processing said adapted routed data in accordance with the second predetermined set of functions of said signalling link of said second Signalling System 7 based data communication protocol.
