In embodiments of mobile device safe driving, a mobile device can display a device lock screen on an integrated display device, and transition from the device lock screen to display a driving mode lock screen. The transition to display the driving mode lock screen occurs without receiving a PIN code entered on the device lock screen. The mobile device implements a safe driving service that is implemented to activate a safe driving mode of the mobile device, and disable features of the mobile device while the safe driving mode is activated.

In a method for vehicle communication, a first vehicle provides first data for communication with a server. The first data is transmitted to a server by radio using a first communication protocol. The server transmits second data to a second vehicle by radio using the first communication protocol, the second data being determined depending on the first data. Depending on the second data, third data is transmitted by the second vehicle to a third vehicle by radio using a second communication protocol.

A method and a trolley for facilitating a passenger's way through an airport terminal, and improved methods for boarding aircrafts. The trolley may include an interface, such as a boarding card reader, for receiving information identifying the passenger and/or the passenger's flight. Mobile wireless communication means may be provided at the trolley for receiving airport information data, such as flight departure gate, delay or cancellation information, from a computer network within an airport terminal. Data output means are provided to communicate information to the passenger. The trolley may be X-ray compliant. A communication interface may be provided at the trolley for communicating with a portable device, such as a smartphone or equivalent means of the passenger. Individually selected information based on passenger identity, destination, position or past collection of passenger behavior may be disseminated to passengers on an individual basis. Passengers may be allowed to pass a gate for aircraft boarding only when called in accordance with a predetermined boarding sequence on the basis of, e.g., seat number or seat row.

In one implementation, a method may comprise: storing a user profile indicative of at least one attribute of a user of a mobile station; determining a measurement value based, at least in part, on a signal from at least one sensor on the mobile station; and estimating a location of the mobile station based, at least in part, on an association of the at least one attribute and the measurement value with a context parameter map database.

A method and system for providing vehicle services using a vehicle and a mobile communications device includes receiving at a vehicle a wireless communication sent from an interface device physically attached to the mobile communications device; linking the interface device with one or more vehicle modules; and communicating between one or more vehicle modules and the mobile communications device via the interface device.

According to an example, a signal space based navigation apparatus may receive traces of wireless signal observations and corresponding pedestrian deadreckoning (PDR) traces between different ones of the wireless signal observations from a plurality of user devices. A plurality of wireless clusters may be generated based on the traces of wireless signal observations. A PDR displacement vector may be generated between two or more of the wireless clusters based on the two or more of the wireless clusters and a subset of the PDR traces corresponding to the two or more of the wireless clusters. A sensing map may be generated based on the plurality of wireless clusters and a plurality of PDR displacement vectors including the PDR displacement vector.

A method comprising obtaining, by a system using a processor, a wireless fingerprint corresponding to a mobile communication device and a subject area in which the mobile communication device is or was positioned. The method also includes obtaining, by the system, an area wireless signal distribution map indicating wireless signal strength values corresponding to multiple wireless transmitters positioned in the subject area, and determining, by the system, based on the wireless fingerprint and the area wireless signal distribution map, a location of the mobile communication device.

In an aspect of embodiments, a mobile electronic device includes a storage, a display, an atmospheric pressure measurement module, a determinator, and a position corrector. The storage stores a floor map for each of floors in a building. The display displays a current position of an own device in the floor on the floor map. The atmospheric pressure measurement module measures atmospheric pressure acting on the own device. The determinator determines whether the own device is moving between the floors based on a change in the atmospheric pressure. The position corrector corrects the current position of the own device to be displayed on the floor map when the determinator determines that the own device is moving between the floors.

A mobile object communication system is configured with the assumption that a base station is fixed. Therefore, signal quality becomes unstable if the base station moves freely. Provided is a control apparatus controlling a relay apparatus that is mounted in a mobile object and relays communication between a base station and a communication terminal, including a mobile object information acquiring section that acquires mobile object information indicating a state of the mobile object and a control section that controls the relay apparatus based on the mobile object information. If the movement speed of the mobile object is judged to be less than a predetermined value, the control section may generate a relay control signal indicating that a relay function of the relay apparatus is to be activated.

A method of communicating vehicle information, the method includes receiving, via a receiver, notification of an incoming communication from a remote device, capturing with a controller vehicle environment information from at least one onboard vehicle sensor device, transmitting, via a transmitter, the vehicle environment information to the remote device.
