First Claim
Patent Images
1. A method for localizing a mobile device having a processor and a memory, the method comprising:
- using the processor, localizing the mobile device during navigation of a sequence of positions along an indoor area based on a data fusion of fingerprint data;
detecting, using the processor, a boundary of a trusted-global positioning system (trusted-GPS) positioning region within the indoor area, based on the localizing of the mobile device in the indoor area; and
upon navigating to the boundary, localizing the mobile device based on GPS position data and a subset of the fingerprint data acquired at the memory of the mobile device, the GPS position data being assigned a higher weight than the subset of the fingerprint data while localizing.

Abstract
A method and system for localizing a mobile device having a processor and a memory. The method comprises, using the processor, localizing the mobile device during navigation of a sequence of positions along an indoor area based on a data fusion of fingerprint data, detecting, using the processor, a boundary of a trusted-global positioning system (trusted-GPS) positioning region within the indoor area, and upon navigating to the boundary, localizing the mobile device based on GPS position data acquired at the memory of the mobile device.

11. A mobile device comprising:
-
a processor; and a memory storing a set of instructions, the instructions executable in the processor to; localize the mobile device during navigation of a sequence of positions along an indoor area based on a data fusion of fingerprint data; detect a boundary of a trusted-global positioning system (trusted-GPS) positioning region within the indoor area based on the localizing of the mobile device in the indoor area; and upon navigating to the boundary, localize the mobile device based on GPS position data and a subset of the fingerprint data acquired at the memory of the mobile device, the GPS position data being assigned a higher weight than the subset of the fingerprint data while localizing. - View Dependent Claims (12, 13, 14, 15, 16, 17, 18, 19, 20)
