Method and apparatus for testing assisted position location capable devices
First Claim
1. A method for testing assisted position location capable devices, the method comprising:
- providing a position determination entity (PDE) simulator that is in communication with a base station simulator;
connecting an assisted position location capable device under test (DUT) to the base station simulator and a global positioning system (GPS) simulator; and
initiating a test sequence wherein the DUT receives a set of predetermined GPS signals and at a desired test sequence time the DUT requests assistance data from the base station simulator, and the base station simulator requests assistance data from the PDE simulator, wherein the PDE simulator provides data that is produced in accordance with the DUT message type and system elapsed time, and is produced independently of the GPS simulator data, to the base station and wherein the base station transfers the PDE data to the DUT.

Abstract
A method and apparatus for testing assisted position location capable devices that includes providing a position determination entity (PDE) simulator that is in communication with a base station simulator simulating one or more base stations and connecting an assisted position location capable device under test (DUT) to the base station simulator and a global positioning system (GPS) simulator. Then, initiating a test sequence wherein the DUT receives a set of predetermined GPS signals and at a desired time the DUT requests assistance data from the base station simulator and the base station simulator requests assistance data from the PDE simulator, wherein the PDE simulator provides data that is independent of the GPS simulator data to the base station and the base station transfers the PDE data to the DUT. The PDE data is a set of predetermined responses to any one of a plurality of DUT requests indexed by elapsed test time.
