Abstract

The present invention establishes a TCP/IP session between terminals which connect to a network on-demand by a dial up PPP. This is achieved by connecting from a local terminal X to a local connection point A of the network by a dial up PPP, calling a remote terminal Y from a secondary server C on the network based on information from the local terminal X and sending a FAX message containing an IP address of the local terminal X, and connecting the remote terminal Y to the network by a dial up PPP by a daemon on the remote terminal Y which is started based on the transmitted FAX message to send the IP address of the remote terminal to the local terminal.

Claims

1. A method of establishing a session between terminals utilizing a network comprising the steps of:

connecting from a local terminal having information for connecting to a remote terminal to a first access point existing on said network;

transmitting session identification information to a first server on the network through the connection to the first access point to request establishing a session between the local terminal and the remote terminal;

transmitting the session identification information to a second server existing on the network, wherein the second server is associated with the remote terminal;

calling said remote terminal from the second server existing on said network based on said session identification information so as to establish a connection from the second server to the remote terminal outside of the network;

transmitting local terminal information to the remote terminal over the connection outside the network;

connecting from the remote terminal to a second access point existing on said network by a daemon on said remote terminal which is started based on said transmitted information from the second server; and

transmitting remote terminal identification information from the remote terminal to the local terminal based on the local terminal information so as to allow a session to be established between the local terminal and the remote terminal.

2. A method of claim 1 in which the session identification information includes authentication information for utilizing the function of said first server and authentication information for utilizing the daemon function on said remote terminal.

3. A method of claim 1 in which connection of said remote terminal to said network is maintained by said daemon while a connection maintenance instruction is periodically transmitted from said local terminal through said network after said remote terminal identification information has been transmitted to said local terminal.

4. A method according to claim 1, wherein the connection from the second server to the remote terminal is a facsimile connection.

5. A system for establishing a session between terminals utilizing a network comprising the steps of:

means for connecting from a local terminal having information for connecting to a remote terminal to a first access point existing on said network;

means for transmitting session identification information to a first server on the network through the connection to the first access point to request establishing a session between the local terminal and the remote terminal;

means for transmitting the session identification information to a second server existing on the network, wherein the second server is associated with the remote terminal;

means for calling said remote terminal from the second server existing on said network based on said session identification information so as to establish a connection from the second server to the remote terminal outside of the network;

means for transmitting local terminal information to the remote terminal over the connection outside the network;

means for connecting from the remote terminal to a second access point existing on said network by a daemon on said remote terminal which is started based on said transmitted information from the second server; and

means for transmitting remote terminal identification information from the remote terminal to the local terminal based on the local terminal information so as to allow a session to be established between the local terminal and the remote terminal.

6. A system according to claim 5 in which the session identification information includes authentication information for utilizing the function of said first server and authentication information for utilizing the daemon function on said remote terminal.

7. A system according to claim 5 in which connection of said remote terminal to said network is maintained by said daemon while a connection maintenance instruction is periodically transmitted from said local terminal through said network after said remote terminal identification information has been transmitted to said local terminal.

8. A system according to claim 5, wherein the connection from the second server to the remote terminal is a facsimile connection.

9. A computer program product recorded in a computer readable media for establishing a session between terminals utilizing a network comprising:

computer program code which connects from a local terminal having information for connecting to a remote terminal to a first access point existing on said network;

computer program code which transmits session identification information to a first server on the network through the connection to the first access point to reqtiest establishing a session between the local terminal and the remote terminal;

computer program code which transmits the session identification information to a second server existing on the network, wherein the second server is associated with the remote terminal;

computer program code which calls said remote terminal from the second server existing on said network based on said session identification information so as to establish a connection from the second server to the remote terminal outside of the network;

computer program code which transmits local terminal information to the remote terminal over the connection outside the network;

computer program code which connects from the remote terminal to a second access point existing on said network by a daemon on said remote terminal which is started based on said transmitted information from the second server; and

computer program code which transmits remote terminal identification information from the remote terminal to the local terminal based on the local terminal information so as to allow a session to be established between the local terminal and the remote terminal.

10. A computer program product according to claim 9 in which the session identification information includes authentication information for utilizing the function of said first server and authentication information for utilizing the daemon function on said remote terminal.

11. A computer program product according to claim 9 in which connection of said remote terminal to said network is maintained by said daemon while a connection maintenance instruction is periodically transmitted from said local terminal through said network after said remote terminal identification information has been transmitted to said local terminal.

12. A computer program product according to claim 9, wherein the connection from the second server to the remote terminal is a facsimile connection.
