  • Patent number: 7197322
    Abstract: A method and system are disclosed for facilitating location-based services. In an exemplary arrangement, when a mobile station is engaged in a data session with a server, the mobile station may be made to initiate a voice call to a designated number. As a result, a switch or other such entity may send a signaling message (such as an Origination Request message) to a central controller, thereby providing the central controller with an indication of the mobile station's current location. The central controller may then make that location information available to the server. In turn, the server may use the location to perform a location based service, such as providing location-based information to the mobile station.
