Abstract

A method of routing a data packet in a communication system includes receiving a data packet at a first communication party operating in accordance with a first protocol. The method also includes adding a header to the data packet to produce modified data packet, the header including an identifier identifying the first protocol, first protocol information, an identifier identifying a second protocol, and second protocol information, and then sending the modified data packet to a second communication party operating in accordance with the second protocol through a first connection.

Claims

1. A method of routing data packets in a communication system, comprising:

receiving a data packet at a first communication party operating in accordance with a first protocol;

adding a header to the data packet to produce a modified data packet, the header including an identifier identifying the first protocol, first protocol information, an identifier identifying a second protocol, and second protocol information; and

sending the modified data packet to a second communication party through a first connection operating in accordance with the second communication.

2. The method of claim 1, wherein the first protocol is an X.25 protocol and the second protocol is a personal handyphone system (PHS) packet management protocol (PPMP).

3. The method of claim 2, wherein the first connection is a transmission control protocol/internet protocol (TCP/IP) connection.

4. The method of claim 3, wherein the first connection is made over an Ethernet.

5. The method of claim 1, wherein the first protocol is an X.25 protocol and the second protocol is a TCP/IP (XOT) protocol.

6. The method of claim 5, wherein the first connection is an X.25 permanent virtual circuit (PVC) connection.

7. The method of claim 6, wherein the first connection is made over an Ethernet.

8. The method of claim 1, wherein the added header further includes a tag identifying the header and packet length information for the modified data packet.

9. The method of claim 1, wherein the second protocol is an X.25 protocol and the first protocol is a personal handyphone system (PHS) packet management protocol (PPMP).

10. The method of claim 9, wherein the first connection is a transmission control protocol/internet protocol (TCP/IP) connection.

11. The method of claim 10, wherein the first connection is made over an Ethernet.

12. The method of claim 1, wherein the second protocol is an X.25 protocol and the first protocol is a TCP/IP (XOT) protocol.

13. The method of claim 12, wherein the first connection is an X.25 permanent virtual circuit (PVC) connection.

14. The method of claim 13, wherein the first connection is made over an Ethernet.

15. The method of claim 1, wherein the receiving step receives the data packet over a second connection.

16. The method of claim 15, wherein the second connection is an X.25 switched virtual circuit (SVC).

17. The method of claim 16, wherein the second connection is made over an integrated service digital network (ISDN).

18. A method of routing data packets in a communication system, comprising:

receiving data packet from a first communication party at a second communication party through a connection, the first communication party operating in accordance with a first protocol and the second communication party operating in accordance with a second protocol, the data packet including a header, the header including an identifier identifying the first protocol, first protocol information, an identifier identifying the second protocol, and second protocol information; and

removing the header at the second communication party.

19. The method of claim 18, wherein the first protocol is an X.25 protocol and the second protocol is a personal handyphone system (PHS) packet management protocol (PPMP).

20. The method of claim 18, wherein the first protocol is an X.25 protocol and the second protocol is a TCP/IP (XOT) protocol.

21. The method of claim 18, wherein the second protocol is an X.25 protocol and the first protocol is a personal handyphone system (PHS) packet management protocol (PPMP).

22. The method of claim 18, wherein the second protocol is an X.25 protocol and the first protocol is a TCP/IP (XOT) protocol.

23. The method of claim 22, wherein the connection is made over an Ethernet.
