Systems and methods for determining indoor location and floor of a mobile device
First Claim
1. A method of determining a floor and location of a device within an indoor space having multiple floors, the device having a processor and a memory, the method comprising:
- gathering, using the processor and the memory, at least one wireless signal data, the at least one wireless signal data including a respective received signal strength measured value;
determining at least one candidate location of the device for each floor of the multiple floors of the indoor space based on the at least one wireless signal data; and
determining the floor and location of the device based on the at least one candidate location of the device for each floor and at least one of a map constraint feature and a heading determined in accordance with device sensor data.

Abstract
Embodiments of the present disclosure related to methods and systems of determining the floor and location of a device in an indoor space having multiple floors.
A map importing module takes a floor map of an indoor space and processes it for further use. A calibration module creates a fingerprint map of the indoor space described by the floor map. A floor localization module searches the fingerprint map of each floor to determine the most likely location for each floor. A floor detection module determines the floor and location based on the most likely locations for each floor and any of map constraints data and device movement data.

11. A system for determining a position of a device in an indoor location, the system comprising:
-
a memory; a processor; a module including instructions stored in the memory that, when executed by the processor, determines the position of the device in the indoor location by performing the steps of; gathering, using the processor and the memory, at least one wireless signal data, the at least one wireless signal data including a respective received signal strength measured value; determining at least one candidate location of the device for each floor of the multiple floors of the indoor space based on the at least one wireless signal data; and determining the floor and location of the device based on the at least one candidate location of the device for each floor and at least one of a map constraint feature and a heading determined in accordance with device sensor data. - View Dependent Claims (12, 13, 14, 15, 16, 17, 18, 19, 20)
