Abstract: An apparatus and method for interworking at least two switching system networks is disclosed. According to the disclosure, interworking is possible by processing a call process message using only one interworking function for both networks. Accordingly, there is no need for interworking protocol such as the ATM Inter-Network Interface (AINI). Preferably, the two networks are a Private Network to Network Interface (PNNI) type network and a B-ISDN User Part (B-ISUP) type network, and an interworking function is coupled to both a PNNI interface and a B-ISUP Interface. Preferably, addresses are registered at each of the interfaces and messages to be transmitted between networks are converted from an origination network protocol to a destination network protocol according to an interworking function table.
