Method and apparatus for influencing wireless signal-based location capability of a mobile device based on one or more onboard sensors

Abstract

The present invention provides various methods, apparatuses, and / or articles of manufacture that may, for example, be implemented to: calculate one or more inferences from signals generated by one or more inertial sensors or environmental sensors, responding to said calculated An error condition is detected inference from a comparison to an initial position or a position fix, and, in response to said detection of said error condition, affecting at least one process at the mobile device at least in part to obtain a position fix.

[0001] Related applications [0002] This application is a PCT application claiming priority to the following U.S. patent applications: U.S. Provisional Patent Application Nos. 61 / 549,539, filed October 20, 2011, and 13 / 622,818, filed September 19, 2012 No. U.S. Nonprovisional Patent Application, which is incorporated herein by reference in its entirety. technical field [0003] The subject matter disclosed herein relates to electronic devices, and more particularly, to methods, apparatus, and articles of manufacture for use in mobile devices having one or more onboard sensors and wireless signal-based positioning capabilities. Background technique [0004] A satellite positioning system (SPS) (e.g., Global Positioning System (GPS) and the like) enables an SPS receiver on a mobile device to generate a mobile-specific The location estimate of the device. The position estimate produced by the SPS receiver may be referred to as a position fix. Typically, an SPS receiver wil...

AI Technical Summary

Problems solved by technology

[0007] While assistance data can allow position fixes to be obtained more quickly and with less energy expenditure, sometimes assistance data can be inaccurate or wrong

As will be appreciated, the use of erroneous assistance data can adversely affect the accuracy of the resulting position fix

Additionally, it is often difficult to determine the accuracy of secondary data before using the data

Therefore, any resulting errors in location fixation cannot be detected until one or more place-based applications using the location fixation data fail
