Abstract

Under one aspect, a system for transmitting an IP-based message from an initiator to a receiver lacking an IP address via a packet-switched (PS) network capable of communicating IP-based messages and a circuit-switched (CS) network capable of communicating non-IP-based messages, includes: a serving node in communication with the PS network and the CS network, the serving node including logic to: receive the IP-based message from the initiator over the PS network; generate a trigger message responsive to the IP-based message, the trigger message including a non-IP-based message including instructions for the receiver to initiate a connection to the PS network; and transmit the trigger message to the receiver via the CS network, and the receiver including logic to initiate a connection to the PS network and to receive the IP-based message responsive to the trigger message. Methods are also disclosed.

Claims

1. A method of transmitting an IP-based message from an initiator to a receiver lacking an IP address via a packet-switched (PS) network capable of communicating IP-based messages, a circuit-switched (CS) network capable of communicating non-IP-based messages, and a serving node in communication with the PS network and the CS network, the method comprising:

generating an IP-based message at the initiator, the IP-based message intended for receipt by the receiver;

transmitting the IP-based message from the initiator to the serving node via the PS network;

responsive to the IP-based message, the serving node generating a trigger message, the trigger message comprising a non-IP-based message comprising instructions for the receiver to initiate a connection to the PS network;

transmitting the trigger message from the serving node to the receiver via the CS network;

responsive to the trigger message, the receiver initiating a connection to the PS network; and

receiving at the receiver the IP-based message.

2. The method of claim 1, wherein the trigger message comprises instructions for the receiver to pull the IP-based message from the serving node via the PS network after initiating a connection to the PS network.

3. The method of claim 1, wherein the trigger message comprises the IP-based message.

4. The method of claim 1, wherein the trigger message comprises instructions for the receiver to request the initiator to send any subsequent IP-based messages via the PS network.

5. The method of claim 1, wherein the initiator comprises a network entity.

6. The method of claim 5, wherein the receiver comprises a mobile handset.

7. The method of claim 1, wherein the initiator comprises a mobile handset.

8. The method of claim 7, wherein the receiver comprises a second mobile handset.

9. The method of claim 1, wherein the trigger message comprises an SMS message.

10. The method of claim 9, wherein the serving node transmits the trigger message to the receiver via a Short Messaging Service Center (SMSC) in the CS network.

11. The method of claim 9, wherein the serving node obtains location information about the receiver from a Home Location Register (HLR) and then transmits the trigger message to the receiver via the CS network.

12. The method of claim 1, wherein the serving node transmits the trigger message to the receiver via a Home Location Register (HLR) in the CS network.

13. The method of claim 1, wherein the trigger message comprises a Push Access Protocol (PAP) message.

14. The method of claim 13, wherein the serving node transmits the trigger message to the receiver via a Push Proxy Gateway (PPG) in the CS network.

15. The method of claim 14, wherein the PPG transmits the trigger message to the receiver via WAP Push technology.

16. The method of claim 1, wherein the trigger message comprises an Unstructured Supplementary Services Data (USSD) message.

17. The method of claim 16, wherein the serving node transmits the trigger message to a Home Location Register (HLR) in the CS network using MAP/TCAP/SS7 protocol.

18. The method of claim 17, wherein the HLR delivers the trigger message to the receiver using “

mobile terminated”

call flow procedures.

19. A system for transmitting an IP-based message from an initiator to a receiver lacking an IP address via a packet-switched (PS) network capable of communicating IP-based messages and a circuit-switched (CS) network capable of communicating non-IP-based messages, the system comprising:

a serving node in communication with the PS network and the CS network, the serving node comprising logic to;

receive the IP-based message from the initiator over the PS network;

generate a trigger message responsive to the IP-based message, the trigger message comprising a non-IP-based message comprising instructions for the receiver to initiate a connection to the PS network; and

transmit the trigger message to the receiver via the CS network, and

the receiver comprising logic to initiate a connection to the PS network and to receive the IP-based message responsive to the trigger message.

20. The system of claim 19, wherein the trigger message comprises instructions for the receiver logic to pull the IP-based message from the serving node via the PS network after initiating the connection to the PS network.

21. The system of claim 19, wherein the trigger message comprises the IP-based message.

22. The system of claim 19, wherein the trigger message comprises instructions for the receiver logic to request the initiator to send any subsequent IP-based messages via the PS network.

23. The system of claim 19, wherein the initiator comprises a network entity.

24. The system of claim 23, wherein the receiver comprises a mobile handset.

25. The system of claim 19, wherein the initiator comprises a mobile handset.

26. The system of claim 25, wherein the receiver comprises a second mobile handset.

27. The system of claim 19, wherein the trigger message comprises an SMS message.

28. The system of claim 27, wherein the CS network comprises a Short Messaging Service Center (SMSC), and wherein the serving node comprises logic to transmit the trigger message to the receiver via the SMSC.

29. The system of claim 27, wherein the CS network comprises a Home Location Register (HLR), and wherein the serving node comprises logic to obtain location information about the receiver from the HLR.

30. The system of claim 19, wherein the CS network comprises a Home Location Register (HLR), and wherein the serving node comprises logic to transmit the trigger message to the receiver via the HLR.

31. The system of claim 19, wherein the trigger message comprises a Push Access Protocol (PAP) message.

32. The system of claim 31, wherein the CS network comprises a Push Proxy Gateway (PPG), and wherein the serving node comprises logic to transmit the trigger message to the receiver via the PPG.

33. The system of claim 32, wherein the PPG transmits the trigger message to the receiver via WAP Push technology.

34. The system of claim 19, wherein the trigger message comprises an Unstructured Supplementary Services Data (USSD) message.

35. The system of claim 34, wherein the CS network comprises a Home Location Register (HLR), and wherein the serving node comprises logic to transmit the trigger message to the receiver via the HLR using MAP/TCAP/SS7 protocol.

36. The system of claim 35, wherein the HLR delivers the trigger message to the receiver using “

mobile terminated”
