Abstract

Methods and systems to communicate data to a mobile station. A request to transfer data from an internet Protocol (IP) network to a mobile station ca be received. Whether the mobile station is registered in a first network of a plurality of networks can be determined. The plurality of networks can include the first network operating under a first protocol and a second network operating under a second protocol, and the second protocol can be different than the first protocol. If the mobile station is registered in the first network, the data can be adapted to be transferred via first network and transferred to the mobile station via the first network.

Claims

1. A method of transferring Internet Protocol (IP) data from an application to a mobile station on one of an IP network and a non-IP network, the mobile station identified by both a mobile station IP address and a mobile station identifier, comprising:

receiving, at a dual messenger, a notification request from the application to transfer IP data to the mobile station, said notification request identifying the mobile station by the mobile station IP address;

determining, at said dual messenger, if the mobile station is registered on an IP network, and if the mobile station is not registered on an IP network, then;

associating, at said dual messenger, the mobile station IP address to the mobile station identifier;

transmitting, from said dual messenger to a message handler, a notification request identified by the associated mobile station identifier; and

determining, at said message handler, if the mobile station is registered on the non-IP network, and if the mobile station is registered on the non-IP network, then transmitting, from said message handler, the IP data to the mobile station via a teleservice server on the non-IP network.

2. The method of claim 1, wherein the IP network is a data-only network.

3. The method of claim 1, wherein the IP network is a Cellular Digital Packet Data (CDPD) network.

4. The method of claim 1, wherein the non-IP network is a voice-only network.

5. The method of claim 1, wherein the non-IP network is a Personal Communications System (PCS) network.

6. The method of claim 1, wherein the non-IP network is a network operating under an IS-136 protocol.

7. The method of claim 1, wherein the non-IP network is a network operating under an IS-95 protocol.

8. The method of claim 1, wherein the mobile station IP address is a Universal Resource Locator (URL) address.

9. The method of claim 1, wherein the mobile station identifier is a mobile identification number (MIN).

10. The method of claim 1, wherein the mobile station identifier is an electronic serial number (ESN).

11. The method of claim 1, wherein determining, at said message handler, comprises generating, at said message handler, a query to the teleservice server.

12. A method of locating a mobile station registered on one of a Cellular Digital Packet Data (CDPD) network and a Personal Communications System (PCS) network, comprising:

receiving at a device a request to transfer Internet Protocol (IP) data from an application to the mobile station, said device coupled to the CDPD network and the PCS network;

querying, from said device, the CDPD network to locate the mobile station;

querying, from said device, the PCS network to locate the mobile station; and

locating the mobile station on one of the CDPD network and the PCS network before communicating with the mobile station.

13. The method of claim 12, wherein the application communicates with the device using Hypertext Transfer Protocol (HTTP).

14. The method of claim 12, wherein the application communicates with the device using Hypertext Mark-up Language (HTML).

15. A system for transferring Internet Protocol (IP) data from an application to a mobile station on one of an IP network and a non-IP network, the mobile station identified by both a mobile station IP address and a mobile station identifier, comprising:

first means for receiving a notification request from the application, said notification request addressed to the mobile station IP address, said first means determining if the mobile station is registered on the IP network, if the mobile station is not registered on the IP network, said first means associating the mobile station IP address to the mobile station identifier and transmitting the mobile station identifier and notification request to a second means;

second means for generating a query to a third means, the query to determine if the mobile station identified by the mobile station identifier is present on the non-IP network;

third means for receiving said query and for interrogating a home location register of the mobile station on the non-IP network; and

fourth means for receiving a request from the second means to obtain notification data from the application if the mobile station is registered on the non-IP network, the fourth means obtaining from the first means an identifier of the application and generating a request for data from the application and transmitting the request for data to the application, the application returning the data to the fourth means, the fourth means delivering the data to the second means, the second means delivering the data to the third means, said third means delivering the data to the mobile station in accordance with a non-IP network protocol.

16. The method of claim 15, wherein the IP network is a data-only network.

17. The method of claim 15, wherein the IP network is a Cellular Digital Packet Data (CDPD) network.

18. The method of claim 15, wherein the non-IP network is a voice-only network.

19. The method of claim 15, wherein the non-IP network is a Personal Communications System (PCS) network.

20. The method of claim 15, wherein the non-IP network is a network operating under an IS-136 protocol.

21. The method of claim 15, wherein the non-IP network is a network operating under an IS-95 protocol.

22. The method of claim 15, wherein the mobile station IP address is a Universal Resource Locator (URL) address.

23. The method of claim 15, wherein the mobile station identifier is a mobile identification number (MIN).

24. The method of claim 15, wherein the mobile station identifier is an electronic serial number (ESN).

25. A method of transferring Internet Protocol (IP) data from an application to a mobile station on one of at least two geographically co-located wireless networks having separate, independent access protocols, the mobile station identified by both a mobile station IP address and a mobile station identifier, comprising:

receiving, at a first device, a notification request from the application to transfer IP data to the mobile station, said notification request identifying the mobile station by the mobile station IP address;

determining, at said first device, if the mobile station is registered on a first wireless network having a first access protocol, and if the mobile station is not registered on the first wireless network having the first access protocol, then;

associating, at said first device, the mobile station IP address to the mobile station identifier;

transmitting, from said first device to a message handler, a notification request identified by the associated mobile station identifier; and

determining, at said message handler, if the mobile station is registered on a second wireless network having a second access protocol, the second access protocol different from the first access protocol, and if the mobile station is registered on the second wireless network having the second access protocol, then transmitting, from said message handler, the IP data to the mobile station via a teleservice server on the second wireless network.

26. The method of claim 25, wherein the first wireless network having a first access protocol is an IP network.

27. The method of claim 25, wherein the first wireless network having a first access protocol is a data-only network.

28. The method of claim 25, wherein the first wireless network having a first access protocol is a Cellular Digital Packet Data (CDPD) network.

29. The method of claim 25, wherein the second wireless network having a second access protocol is a non-IP network.

30. The method of claim 25, wherein the second wireless network having a second access protocol is a voice-only network.

31. The method of claim 25, wherein the second wireless network having a second access protocol is a Personal Communications System (PCS) network.

32. The method of claim 25, wherein the second wireless network having a second access protocol is a network operating under an IS-136 protocol.

33. The method of claim 25, wherein the second wireless network having a second access protocol is a network operating under an IS-95 protocol.

34. The method of claim 25, wherein the mobile station IP address is a Universal Resource Locator (URL) address.
