In a communication system, Position Determining Equipment (PDE) receives location queries from wireless communication devices, determines geographic location data for the wireless communication devices using a plurality of different position fix types, and transfers the geographic location data to the wireless communication devices. The PDE also determines location session data indicating cumulative session time for each of the different position fix types. A PDE data processing system adds the cumulative session time for each of the different position fix types to determine total session time for all of the position fix types. The PDE data processing system divides the total session time for all of the position fix types by the total time to determine an indicator of average concurrent use of the PDE. |
