Method and system for minimizing connect-time charges associated with dial-up data networks

摘要

A method to dynamically connect an originating computer to a receiving computer on a dial-up network, such as the Internet. The originating computer calls the receiving computer over the Public Service Telephone Network (PSTN); the receiving computer detects the call but does not answer it so that no PSTN charges are incurred; then both the receiving computer and originating computer call up the dial-up network and one of the computers obtains the network address of the other computer to establish a communication link between them.
