摘要

Communication between telecommunications networks and computer systems used by financial institutions to allow processing customer requests to pay for telecommunication services with credit cards is described. In particular, communication that allows both real-time authorization and settlement of charges needed to bill the customer is explained. In addition, a system and method for protocol conversion between a client server protocol used by telecommunications networks and a packet switching network protocol used by financial institutions is provided. Client server protocols include protocols used by caller interaction processes such as UDP/IP. Packet switching network protocols include protocols used by financial processors such as X.25. The system method of the present invention may be used for communication between other networks and computer systems that use UDP/IP in X.25.
