A method and system for detecting a transition in positioning state of a mobile device relative to an indoor facility. The method, executed in a processor of the mobile device, comprises monitoring, based at least in part on global positioning system (GPS) data, for a positioning state of the mobile device as one of an indoor and an outside location relative to an indoor facility, determining a set of probabilistic weightings for respective ones of ambient data and the GPS data, the ambient data including one or more of received signal strength data, signal connectivity data, magnetic data, ambient lighting data and barometric data, and detecting a transition in positioning state of the mobile device from one of the indoor and the outside locations to another of the indoor and the outside locations when a weighted sum value based at least in part on the set of probabilistic weightings is one of above and below a predetermined state transition value.

Aspects of the disclosure relate generally to localizing mobile devices. In one example, a first location method associated with a first accuracy value may be used to estimate a location of the mobile device. A confidence circle indicative of a level of confidence in the estimation of the location is calculated. The confidence circle may be displayed on a mobile device. When other location methods become available, the size of the displayed confidence circle may be expanded based on information from an accelerometer of the client device or the accuracy of the other available location methods. This may be especially useful when the mobile device is transitioning between areas which are associated with different location methods that may be more or less accurate.

This disclosure relates generally to surveillance, and more particularly to perform entry and exit monitoring of a user. In an embodiment, the system identifies an entry event (during which a user enters a room being surveilled) and/or an exit event (during which a user leaves a room being surveilled), based on a Bluetooth Low Energy (BLE) based system. This system uses two receivers one positioned outside and the other positioned inside the room being surveilled, to receive BLE beacon transmitted by a user who is in motion. Based on relative change in Received Signal Strength Indicator (RSSI) values of this beacon with respect to the first and second receivers, the system identifies direction of movement of the user, and in turn, determines one of the entry or exit events.

A mobile computer may determine it is located in a vehicle or a conveyance based on a measured distance, satellite related positioning information, and a touch input.

Systems and methods for estimating whether a receiver is indoors or outdoors. Certain approaches evaluate data associated with a network of beacons to determine whether the receiver is indoors or outdoors. Such evaluation may include any of determining whether azimuthal angles corresponding to the beacons meet an azimuthal angle condition, determining whether elevation angles corresponding to the beacons meet an elevation angle condition, determining whether signal strengths corresponding to the beacons meet a signal strength condition, and determining whether other measurements associated with the beacons meet other measurement conditions.

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.

Embodiments of the disclosure provide systems and methods for positioning a gateway of an architecture. The method may include determining a trajectory of a mobile device based on motion data acquired by the mobile device and a movement model, acquiring a first end position of the trajectory of the mobile device, detecting that the mobile device enters or exits the architecture, and determining a second end position of the trajectory upon the detection as the position of the gateway.

A mobile computer may determine it is located in a vehicle or a conveyance based on a measured distance, satellite related positioning information, and a touch input.

A method for computing a correction to a compass heading for a portable device worn or carried by a user is described. The method involves determining a heading for the device based on a compass reading, collecting data from one or more sensors, determining if the device is indoors or outdoors based on the collected data, and correcting the heading based on the determination of whether the device is indoors or outdoors.

Disclosed is an electronic device including a first circuit for measuring positions using a first positioning method; a second circuit for measuring positions using a second positioning method; a memory for storing information on a service zone; and a processor is configured to identify a first position using the first circuit; determine whether the first position is included in the service zone; identify a second position using the second circuit when the first position is included in the service zone; and determine the second position to be a position of the electronic device.
