METHODS OF POSITION-LOCATION DETERMINATION USING A HIGH-CONFIDENCE RANGE, AND RELATED SYSTEMS AND DEVICES

摘要

Methods of position-location determination are provided. The methods may include determining a first range for a wireless user device, using signaling from a high-confidence first ranging source. The methods may include determining a second range for the wireless user device, using signaling from a second ranging source that corresponds to a lower confidence than the high-confidence first ranging source. Moreover, the methods may include determining a position-location of the wireless user device by using a first geometric shape that is defined based on the first range. Related wireless user devices and central systems and/or central devices are also described.

1. A method of position-location determination, the method comprising:
determining a first range for a wireless user device, using signaling from a high-confidence first ranging source; determining a second range for the wireless user device, using signaling from a second ranging source that corresponds to a lower confidence than the high-confidence first ranging source; determining whether first and second geometric shapes that are defined based on the first and second ranges, respectively, intersect; determining a third range for the wireless user device, using signaling from a third ranging source; and determining a position-location of the wireless user device by using the third range to indicate a position along a perimeter of the first geometric shape.
