METHOD AND SYSTEM FOR GENERATING AND PROPAGATING LOCATION INFORMATION BY A MOBILE DEVICE USING SENSORY DATA
First Claim
1. A method for communication, the method comprising:
- in a mobile device comprising one or more movement sensors, and/or a location device;
determining an initial absolute location of said mobile device, wherein said determining comprises estimating said initial absolute location of said mobile device based on location data of one or more communication devices that are communicatively coupled to said mobile device; and
when said mobile device is moving and subsequent absolute location of said mobile device cannot be determined;
tracking movement of said mobile device utilizing said one or more movement sensors; and
generating location related data relative to said initial absolute location of said mobile device based on said tracking of said movement of said mobile device.

Abstract
A mobile device may determine its initial absolute location; may track using a plurality of sensors, its movements relative to the initial absolute location; and may generate location related data for a location based on that tracking. Tracking movement of the mobile device may comprise generating data corresponding to three-dimensional (3D) linear and/or rotational changes in position and/or location of the mobile device. The initial absolute location may be determined directly by the mobile device, based on GNSS signals and/or assisted GNSS (A-GNSS) data received from one or more location servers; and/or it may be estimated based on a location of a communication device that is communicatively coupled to the mobile device. The generated location related data may propagated by the mobile device to other mobile and/or communication devices, and/or to the location servers, where a reference database for supporting location related services (LBS) may be updated accordingly.
