Changes in the positioning scheme used by user equipment during transitions between indoor and outdoor spaces for closed environments

摘要

In an embodiment, a user equipment (UE) tracks its location using a first positioning scheme (PS) (e.g., an indoor PS or outdoor PS) while operating inside or outside of an enclosed environment, whereby the UE maintains transition region information related to the enclosed environment that characterizes one or more outdoor-to-indoor (OI) and/or indoor-to-outdoor (IO) transition regions of the enclosed environment. If the UE determines it has entered a transition region of the enclosed environment based on its location tracking using the first PS, the UE begins to track its location using a second PS. When the quality of the second PS rises above a threshold (e.g., such as the UE moves further inside or outside of the enclosed environment), the UE can switch to the second PS and turn off the first PS.
