WIRELESS APPLICATION PROTOCOL (WAP) APPLICATION LOCATION BASED SERVICES (LBS)
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.
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.
