20090267838 | METHOD AND APPARATUS TO AUTOMATICALLY TRIGGER POSITION LOCATION FIXES FOR EXTERNAL DEVICES - A method and apparatus automatically triggers position location fixes for external devices. In one embodiment of the present invention, a mobile station generates position location data for a position location function in an external device in response to determining that the mobile station is electrically coupled to the external device, and in response to determining that the position location function in the external device is active. The mobile station does not generate position location data for the position location function in the external device in response to determining that the mobile station is electrically decoupled from the external device, or in response to determining that the position location function in the external device is not active. | 10-29-2009 |
20090311984 | FM Band Availability Based on GPS - Methods and apparatus for determining an available FM frequency channel for interfacing with FM modulated output signals from a wireless device are described herein. A SPS receiver, such as a GPS receiver, can determine its position based on conventional techniques. The SPS receiver can determine one or more available FM channels over which audio output may be transmitted. The SPS receiver can use the determined position to access a local data base of available channels. Alternatively, the SPS receiver can use the determined position to access a local database of allocated channels in order to determine one or more available channels. The SPS receiver may display a prompt or message that indicates an FM channel over which output audio is modulated. | 12-17-2009 |
20100279705 | METHODS AND SYSTEMS FOR DERIVING SEED POSITION OF A SUBSCRIBER STATION IN SUPPORT OF UNASSISTED GPS-TYPE POSITION DETERMINATION IN A WIRELESS COMMUNICATION SYSTEM - In a method and system for deriving a seed position of a subscriber station in a wireless communications system in supporting unassisted GPS-type position determination is provided, the subscriber station receives overhead messages from the wireless communications system, and derives the seed position from the parameter values. The subscriber station may use a data structure in its memory and map possible parameter values to corresponding positions that may serve as the seed positions. | 11-04-2010 |
20120064911 | PROCEDURE TO INCREASE POSITION LOCATION AVAILABILITY - A device, method and system are provide which permits the methodology used to make the position determination to change dynamically in connection with achieving a position fix of a desired accuracy. | 03-15-2012 |
20120142344 | METHOD AND APPARATUS FOR SUPPORTING LOCATION SERVICES WITH ROAMING - Techniques for supporting location services with roaming are described. A method of supporting location services (LCS) for a mobile station roaming from a home network and communicating with a visited network includes receiving a domain name system (DNS) query at a DNS of the home network from a packet data serving node (PDSN) of the home network. The method also includes sending to the mobile station from the DNS of the home network an address of a serving position determining entity (S-PDE) in the visited network. | 06-07-2012 |
20120149369 | METHOD AND APPARATUS FOR SUPPORTING LOCATION SERVICES WITH ROAMING - Techniques for supporting location services (LCS) with roaming are described. A method of supporting LCS in a network comprising a Secure User Plane Location (SUPL) enabled terminal (SET), a home SUPL location center (H-SLC), and a serving SUPL location center (S-SLC) includes receiving, at the H-SLC, a location request message for a location of the SET, where the location request message comprises an indication of a network location of the SET. The method includes sending, to the S-SLC in response to the location request message, a roaming request message. The method includes receiving, from the S-SLC in response to the roaming request message, a location report message comprising a position of the network location. The method also includes sending a reporting message comprising the position of the network location of the SET as the location of the SET. | 06-14-2012 |
