Determining building floor level of wireless mobile communication device
First Claim
1. A floor-reporting computer system for determining a specific floor in a building on which a wireless mobile communication device is located, the system comprising:
- a network interface configured to receive a plurality of device locations from a network communication system which originated from the wireless mobile communication device and which are indicative of the horizontal and vertical locations of the wireless mobile communication device; and
a computer processing system configured to;
receive a first device location, and a second device location of the plurality of device locations from the network interface, based on a corresponding first location technique and a second location technique, different from the first location technique, wherein the first and second location techniques are selected from a group of different location techniques consisting of;
a GPS receiver in the wireless mobile communication device, signal triangulation at the wireless mobile communication device, WiFi geo-location at the wireless mobile communication device, and RF fingerprinting at the wireless mobile communication device, wherein the first and the second location techniques are used simultaneously, anddetermine floor location information, upon combining the second device location with the first device location to generate a third device location indicative of an enhanced horizontal position and an enhanced vertical position of the wireless communication device;
wherein the floor location information is indicative of the specific floor in the building on which the wireless mobile communication device is located.

Abstract
A floor-reporting computer system may determine the specific floor in a building on which a wireless mobile communication device is located. A network interface may receive device location information from a network communication system which originated from the wireless mobile communication device and which is indicative of the horizontal and vertical location of the wireless mobile communication device. A computer processing system may receive the device location information from the network interface and determine floor location information indicative of the specific floor in the building on which the wireless mobile communication device is located based on the device location information. The computer processing system may consult one or more databases when determining the floor location information, such as a building location database, a ground elevation database, a building floor height database, and/or an atmospheric air pressure database.
