Abstract

A central site such as an Internet Service Provider (ISP) monitors information requests incoming from devices on a network such as the Internet. If the incoming information indicates that the services of a remote, off-line computer is required, the ISP signals the off-line computer via an out-of-band signal. In response to the signal, the off-line computer connects to the Internet through the ISP in its normal manner, and subsequently responds to the devices.

Claims

1. A method of connecting an off-line computer and an on-line computer via a network, the method comprising the steps of:

monitoring the network for a request from the on-line computer to access a second computer;

determining that said second computer is off-line;

notifying the second computer of the request via a signal, provided the second computer is off-line;

discontinuing the signal;

waiting for the off-line computer to initiate contact with the network; and

accepting a request by the off-line computer to connect to the network.

2. The method of claim 1, wherein the notifying step includes the substep of notifying the second computer with a DTMF signal, provided the second computer is off-line.

3. The method of claim 1, wherein the step of accepting a request by the off-line computer includes the substep of assigning the off-line computer an IP address.

4. The method of claim 3, further including the step of updating a domain name server with the assigned IP address of the off-line computer.

5. The method of claim 1, wherein the step of monitoring the network further includes monitoring the network for domain name lookup requests.

6. The method of claim 1, wherein the step of waiting for the off-line computer to initiate contact with the network includes the substep of acting as a proxy for the off-line computer.

7. The method of claim 1, wherein the step of notifying the second computer includes the step of signaling the second computer with an out-of-band command signal, provided the second computer is off-line.

8. The method of claim 7, wherein the step of notifying the second computer further includes the step of using the command signal to indicate that the second computer should call a specified diagnostic number for service or support.

9. The method of claim 7, wherein the step of notifying the off-line computer further includes using the command signal to indicate that the off-line computer should call back in N minutes, where N is a positive integer.

10. A computer readable medium containing instructions for causing a computer at a Network Service Provider that provides access to a network to perform the steps of:

monitoring the network for a request from an on-line computer system to access a second computer system;

determining that said second computer is off-line;

notifying the second computer system of the request via a signal, provided the second computer is off-line;

discontinuing the signal;

waiting for the off-line computer system to initiate contact with the network; and

accepting a request by the off-line computer to connect to the network.

11. A computer data signal embodied in a carrier wave and representing sequences of instructions which, when executed by a computer system at a Network Service Provider, causes said computer system to perform the steps of:

monitoring a network for a request from an on-line computer system to access a second computer system;

determining that said second computer is off-line;

notifying the second computer system of the request via a signal, provided the second computer is off-line;

discontinuing the signal;

waiting for the off-line computer system to initiate contact with the network; and

accepting a request by the off-line computer to connect to the network.

12. A computer system comprising:

an out-bound processing circuit configured to initiate an out-of-band connection with off-line computers;

a local domain name server configured to convert a mnemonic address lookup request to a corresponding IP address, to determine if the computer associated with the IP address is off-line and to instruct the out-bound processing circuit to initiate an out-of-band connection with the off-line computer when the mnemonic address lookup request is for the off-line computer; and

an in-bound processing circuit configured to receive connection requests from the off-line computer in response to the out-of-band connection.

13. The computer system of claim 12, further including a status table holding phone numbers and connection status information relating to the remote computers.

14. A method of connecting an off-line computer to a Network, the method comprising the steps of:

receiving a command by an off-line computer, the command informing the off-line computer that a device is attempting to contact the off-line computer;

discontinuing reception of the transmission signals; and

initiating contact with a Network Service Provider that provides access to a network in response to the received command.

15. The method of claim 14, further including the step of communicating with the device through the Network Service Provider.

16. The method of claim 14, further including the substep of dialing into the Network Service Provider via a dial-up connection.

17. The method of claim 14, wherein the step of initiating contact is performed N minutes after the command is received, where N is a positive integer and is specified by the command.

18. A computer readable medium containing instructions for causing an off-line computer to connect to a network by causing the off-line computer to perform the steps of:

receiving a command by an off-line computer, the command informing the off-line computer that a device is attempting to contact the off-line computer;

discontinuing reception of the transmission signals; and

initiating contact with a Network Service Provider that provides access to a network in response to the received command.

19. The computer readable medium of claim 18, further including instructions causing the off-line computer to communicate with the device through the Network Service Provider.

20. The computer readable medium of claim 18, further including instructions causing the off-line computer to dial into the Network Service Provider via a dial-up connection.

21. The computer readable medium of claim 18, further including instructions causing tile off-line computer to perform the step of initiating contact N minutes after the command is received, where N is a positive integer and is specified by the command.

22. A computer data signal embodied in a carrier wave and representing sequences of instructions which, when executed by an off-line computer, causes the off-line computer to perform the steps of:

receiving a command by an off-line computer, the command informing the off-line computer that a device is attempting to contact the off-line computer;

discontinuing reception of the transmission signals by the off-line computer; and

initiating contact with a Network Service Provider that provides access to a network in response to the received command.

23. The computer data signal of claim 22, further causing the off-line computer to perform the step of communicating with the device through the Network Service Provider.

24. The computer data signal of claim 22, further causing the off-line computer to perform the step of dialing into the Internet Service Provider via a dial-up connection.

25. The computer data signal of claim 22, further causing the off-line computer to perform die step of initiating contact N minutes after the command is received, where N is a positive integer and is specified by the command.
