Abstract

A Location Based Service (LBS) enabled Wireless Application Protocol (WAP) application operating in a microbrowser of a mobile device is given the ability to trigger a network initiated LBS request from a WAP application server. The WAP application server (or SMS gateway) acts as a proxy and issues an LBS request to a relevant LBS platform. In response, the WAP application server receives the requested location information from the LBS platform and initiates a WAP session with the mobile device using a WAP PUSH command. In this way, the WAP application running on the mobile device can act on requested and received LBS input from a network LBS platform.

Claims

1. (canceled)

2. A method comprising:

receiving, at a Wireless Application Protocol (WAP) application server via a WAP session between the WAP application server and a mobile device, a mobile-triggered request for location information of the mobile device;

terminating, at the WAP application server, a WAP session with the mobile device in response to receiving the mobile-triggered request;

initiating, in response to the mobile-triggered request, a network-initiated location based service (LBS) request from the WAP application server to an LBS server for location information for the mobile device;

receiving, at the WAP application server, the location information for the mobile device from the LBS server; and

pushing, in response to receipt of the location information for the mobile device, the location information to the mobile device via a WAP PUSH command.

3. The method of claim 2, wherein:

the location information is provided to the WAP application server via a WAP reply.

4. The method of claim 2, wherein:

the WAP application server supports multiple simultaneous WAP sessions.

5. The method of claim 2, further comprising:

notifying the mobile device that the WAP application server is in communication with the LBS server.

6. The method of claim 2, wherein:

the mobile-triggered request is generated by a browser operating on the mobile device.

7. The method of claim 2, wherein:

the mobile device is a wireless phone.

8. The method of claim 2, wherein:

the mobile device is a laptop computer.

9. The method of claim 2, wherein:

the mobile device is a personal digital assistant.

10. The method of claim 2, wherein:

the network-initiated LBS request is a Mobile Location Protocol (MLP) request.

11. The method of claim 2, wherein:

the network-initiated LBS request is a Location Enabling Server (LES) request.

12. The method of claim 11, wherein:

the LES request triggers an Assisted Global Positioning System (AGPS) location determination for the mobile device.

13. A Wireless Application Protocol (WAP) application server comprising:

a memory to store machine readable instructions; and

one or more processors to access the memory and execute the machine readable instructions, the machine readable instructions comprising;

a receiver that receives a mobile-triggered request for location information for the mobile device via a given WAP session between the WAP application server and the mobile device;

a location requestor that sends a network-initiated location based service (LBS) request from the WAP server to an LBS server for location information of the mobile device in response to the mobile-triggered request;

a WAP module that provides location information received from the LBS server to the mobile device via a WAP PUSH command on another WAP session between the WAP application server and the mobile device in response to the mobile-triggered request.

14. The WAP application server of claim 13, wherein:

the WAP application network server supports multiple concurrent WAP sessions.

15. The WAP application server of claim 13, wherein:

the WAP module notifies the mobile device that contact with the LBS server has been initiated in response to the location requestor providing the network-initiated LBS request.

16. The WAP application server of claim 13, wherein:

a browser operating on the mobile device provides the mobile-triggered request for location information.

17. The WAP application server of claim 13, wherein:

the mobile device is one of a wireless phone and a laptop computer.

18. The WAP application server of claim 13, wherein:

the network-initiated LBS request is a Mobile Location Protocol (MLP) request.

19. A method comprising:

sending, from a mobile device via a given Wireless Application Protocol (WAP) session a mobile-triggered request for location information of the mobile device; and

receiving, via a WAP PUSH over another WAP session, location information for the mobile device, wherein the location information is generated by a location-based services (LBS) server in communication with the WAP application server.

20. The method of claim 19, further comprising:

receiving, from the WAP server via the given WAP session, an notification that a request for the location information has been initiated by the WAP application server to the LBS server.

21. The method of claim 19, wherein:

the given WAP session is terminated after receipt of the notification.
