System with wake up server and wake up monitor for facilitating dial up

Abstract

A wake up server permits both parties (the receiver and the responder) to be connected to the Internet only when a request or response is to be delivered. The wake up server consists of two parts; a server, which contains the telephone numbers of all machines (application partners) that dial to connect to the Internet, and on each application partner, a process monitor that monitors the telephone line and detects when a ring occurs. When an application partner is unable to deliver a request or response to another application partner, a request is sent to the wake up server to activate the target application partner. The wake up server dials the telephone number of the requested application partner and waits for ringing to occur. The wake up server then disconnects (i.e., hangs up the telephone line). The wake up monitor detects the ring and immediately dials to connect to the Internet. When the original application partner tries to send the response or request again, the process will now be successful. Application partners stay connected until a specified time of inactivity or other application initiated event signaling that the connection is no longer required. The application partners then activate their respective wake up monitors, which disconnect the application partners from the Internet and wait again for a ring from the wake up server.
