US Patent 11249169 Site matching for asset tracking

A method of determining locations of tracking devices may include receiving a data ping from a tracking device, where the data ping may be sent in response to the tracking device detecting a predetermined sequence of movements indicating a logistic event from a plurality of predefined logistics events. The method may additionally include accessing a hierarchical logistics flow for the tracking device, where the hierarchical logistics flow may include an ordered sequential list of event sites through which the tracking device is likely to move. The method may further include assigning an event site from the ordered sequential list of event sites based on the logistic event and the hierarchical logistics flow.
