1. A method for forging location measurements at a wireless device, comprising:
- determining, at the wireless device, a Cell-ID for a cell in a vicinity of a false location;
receiving, at the wireless device, an identification of a set of satellites that are within view from the false location;
generating, at the wireless device, forged location measurements that characterize satellite signals from a subset of the set of satellites that would be received at the false location; and
providing, from the wireless device, the forged location measurements.

Abstract
A method for forging location measurements at a wireless device can include determining, at the wireless device, a Cell-ID for a cell in a vicinity of a false location. The method can also include receiving, at the wireless device, an identification of a set of satellites that are within view from the false location. The method can further include generating, at the wireless device, forged location measurements that characterize satellite signals from a subset of the set of satellites that would be received at the false location. The method can still further include providing, from the wireless device, the forged location measurements.

9. A wireless device for forging location measurements, comprising:
-
a memory for storing machine executable instructions; and a processor to execute the machine executable instructions, the machine executable instructions configured to; determine an identification of a set of satellites that are within view from a false location; generate forged location measurements that characterize satellite signals from a subset of the set of satellites that would be received at the false location; introduce random errors into the forged location measurements; and output the forged location measurements. - View Dependent Claims (10, 11, 12, 13, 14, 16)

15. A wireless device for forging location measurements, comprising:
-
a memory for storing machine executable instructions; and a processor to execute the machine executable instructions, the machine executable instructions configured to; determine an identification of a set of satellites that are within view from a false location; query a cell database to retrieve a Cell-ID for a cell in the vicinity of the false location; generate forged location measurements that characterize satellite signals from a subset of the set of satellites that would be received at the false location; and output the forged location measurements.

17. A system for forging location measurements, the system comprising:
-
a computer having a location based application (LBA) executing thereon, the LBA being configured to provide a request for a location of a secure user plan location (SULP) enabled terminal (SET) to an SULP location platform (SLP); the SLP being configured to provide a location request message to the SET in response to receiving the request of the location of the SET; the SET being configured to; receive, from the SLP, the location request message; determine a Cell-ID for a cell in a vicinity of a false location in response to the location request message; determine an identification of a set of satellites that are within view from the false location; generate forged location measurements that characterize satellite signals from a subset of the set of satellites that would be received at the false location; and provide the forged location measurements to the SLP. - View Dependent Claims (18, 19, 20, 21)
