Abstract: A method performed in an electronic device for establishing, in an energy-efficient way, a wireless connection to a cellular network, where the electronic device is configured to support wireless connection to a plurality of cellular networks. The method includes obtaining a current position of the electronic device; determining, as a function of the current position, a set of available cellular networks, said set being a subset of the plurality of cellular networks that are supported by the electronic device; and scanning the set of available cellular networks.

Abstract: A method for tracking an object in a transportation system is described. The method includes determining, at a first time, a first location of the object based on a positioning system. A first area includes the first location. The method includes determining, based on a movement sensor, that the object is moving. The movement sensor determines that the object is moving at a second time that is after the first time. The method includes determining, at a third time that is after the second time, based on the positioning system, a second location of the object, and setting the moving time of the object to be the second time, responsive to determining that the object has moved to the second location that is in a second area that is different from the first area. Related systems, devices and computer program products are also described.
