Devices, systems and methods for location assistance verification

Devices, systems and methods are disclosed which authorize applications to access location-determining technologies on user devices and on service provider networks. An A-GPS agent resident on the device acts as an interface between applications requesting access to the user's location from the A-GPS chipset and helps to coordinate connections between the A-GPS chipset and the Assistance Server. Introduced into the network maintained by the service provider is a verification server running an application identification engine which determines if the request for preliminary location information engendered by the requesting application is approved.
