Abstract
The cellular device accesses a GPS/GNSS chipset embedded within the cellular device. The GPS/GNSS chipset calculates pseudorange information for use by the GPS/GNSS chipset. The cellular device extracts the pseudorange information from the GPS/GNSS chipset for use elsewhere in the cellular device outside of the GPS/GNSS chipset.

26. A mobile device comprising:
-
memory coupled with a bus; a Global Positioning System/Global Navigation Satellite System (GPS/GNSS) embedded receiver coupled with the bus; a communications system coupled with the bus; and one or more processors coupled with the bus, wherein the the one or more processors are configured to; send a message to the GPS/GNSS embedded receiver to initiate an E911 activity, receive pseudorange information provided by the E911 activity, send a second message to the GPS/GNSS embedded receiver to cancel the E911 activity before transmission of the pseudorange information external to the mobile device, and determine a position fix of the mobile device based on the pseudorange information. - View Dependent Claims (27, 29, 30, 48, 49, 50, 51, 52, 53, 54, 55)
