A method of tracking entry to and exit from a confined space includes a portable radio beacon placed proximate to but outside the confined space transmitting a first radio signal with an identifier that is associated with the confined space. A mobile device receives the first radio signal, measures a first real-time value of a first measure of received signal strength or quality, and transmits a second radio signal with the identifier and the first real-time value. A base station receives the second radio signal, measures a second real-time value of a second measure of received signal strength or quality, and transmits data including the identifier, and the first and second real-time values. A computer receives the data, determines proximity of the mobile device to the confined space from the identifier, and determines whether the mobile device is outside or inside the confined space from the real-time values.

A method for monitoring vehicle motion using a mobile device associated with a user including collecting activity data at a mobile device associated with the user; determining a user activity state based on the activity data; determining motion data collection parameters associated with an operating state of the mobile device, based on the user activity state; and collecting motion data at the mobile device based on the motion data collection parameters.

Apparatuses and methods of securing Global Navigation Satellite Systems are disclosure. In one exemplary embodiment, a mobile device may comprise: a communication interface configured to monitor signals from a plurality of satellites, a processor configured to determine impairment of one or more satellites in the plurality of satellites using the signals form the plurality of satellites, a memory configured to store a status of the determined impairment of one or more satellites in the plurality of satellites, and the communication interface that transmits the status of the determined impairment of the one or more satellites in the plurality of satellites to a server. The processor further determines a position of the mobile device using the status of the determined impairment of one or more satellites in the plurality of satellites, and stores the determined position and a corresponding digital certificate indicative of authenticity of the determined position in a memory.

Methods and techniques are described for supporting location services for a user equipment (UE) in a Fifth Generation wireless network in which a base station, such as a gNB or ng-eNB, broadcasts a Positioning Reference Signal (PRS) in a plurality of different directions and at a plurality of different times. A PRS muting configuration is used in which PRS is muted using a time based and angle based pattern to prevent interference between beams transmitted by other base stations and/or to prevent interference between beams transmitted simultaneously by a single base station. The time based and angle based muting pattern, for example, may provide an indication for each direction in the plurality of different directions and for each time in the plurality of different times and as to whether the PRS is transmitted or muted by the base station.

Aspects of the present disclosure provide methods and apparatuses for sounding reference signal (SRS) enhancements. An exemplary method performed by a user equipment generally includes receiving information indicating a symbol, in a sub-frame of a radio frame used to communicate in the wireless network, for transmission of sounding reference signals (SRSs), wherein a location of the symbol in the sub-frame is based, at least in part, on a location of the UE and transmitting a SRS in the symbol based on the received information.

Devices and methods for providing a retrievable record of the times of the actual aircraft movements such as the Gate Out time when the aircraft leaves the gate or parking position, the Wheels Off time when the aircraft takes off, the Wheels On time when the aircraft touches down during landing, and the Gate In time when the aircraft arrives at the gate or parking position (OOOI times). A mobile device for logging data onboard an aircraft comprises: a motion sensor; a clock; a non-transitory tangible computer-readable storage medium for storing motion data from the motion sensor and associated time data from the clock; and a data processing system configured to identify stored motion data representing respective acceleration/deceleration vectors of the mobile device motions that correspond to aircraft gate departure and arrival and aircraft takeoff and landing. The OOOI times are automatically logged in the non-transitory tangible computer-readable storage medium.

A locating method in a multi-connectivity network, a terminal device, and a location management function entity are provided. The locating method may include determining, by the terminal device, the position of the terminal device using a first radio access technology (RAT). The locating method may also include sending, by the terminal device, a locating message of the terminal device to a location management function entity through signaling over an air interface using a second RAT. The locating message of the terminal device may include a first locating parameter of a cell of a fist node corresponding to the first RAT and a second locating parameter of a cell of a second node corresponding to the second RAT.

Drone-based systems and methods for conducting a modified inspection of a delivery vehicle are described. A system has a delivery vehicle transceiver and an inspection drone paired to the vehicle that aerially inspects the vehicle. The delivery vehicle transceiver has a user interface and a wireless radio, while the paired inspection drone has a housing, onboard controller, memory storage, lifting engines, and a communication interface. The drone's onboard controller is operative to identify different existing delivery vehicle inspection points from an inspection profile record; receive an inspection update message from the communication interface; update the existing delivery vehicle inspection points with additional inspection points to yield a targeted inspection points corresponding to respective parts of the delivery vehicle; and conduct the modified inspection of the delivery vehicle by gathering the detected sensor-based inspection information related to each of the targeted inspection points.
