Picocell and control method for wireless data transmission in an aircraft as well as the aircraft
A picocell in an aircraft for the wireless transmission of data between at least a mobile station in the aircraft and a base station in the aircraft in which a communications connection between the at least one mobile station in the aircraft and a subscriber in a terrestrial communications network is established via the base station. In order to enable passengers automatically the use of their mobile radio devices, when no risk of danger to the flying operation is to be expected, or otherwise to refer them to a corresponding ban, a flight control device is provided for detecting flight data and for setting up the picocell in dependence on the flight data.
1. A picocell in an aircraft for the wireless transmission of data between at least one mobile station in the aircraft and a base station in the aircraft, wherein a communications connection between the at least one mobile station in the aircraft and a subscriber in a terrestrial communications network is established via the base station and
wherein a flight control device is provided for detecting flight data and for automatically switching the base station off and on in dependence on the flight data in order to set up the picocell if a safe flying phase is reached and to switch off the picocell if the safe flying phase is not reached,
wherein the flight control device is connected to at least one display unit in the aircraft and adapted to control the at least one display unit to:
activate clearance signs clearing use of the at least one mobile station if the safe flying phase is reached and the communications connection has been established between the base station and the terrestrial communications network, and
activate prohibition signs prohibiting use of the at least one mobile station if the safe flying phase is not reached.
2. The picocell according to claim 1 which is provided on board the aircraft, after the flight control device has sent a command to the base station to switch on the base station.
3. The picocell according to claim 1 in which the at least one display device is integrated in a passenger supply unit (PSU) above the seats.
4. An aircraft with at least one picocell for the wireless transmission of data between at least a mobile station and a base station in the aircraft, wherein a communications connection is set up between the at least one mobile station in the aircraft and a subscriber in a terrestrial communications network via the base station,
wherein a flight control device is provided for detecting flight data and for automatically switching the base station off and on in dependence on the flight data in order to establish the at least one picocell if a safe flying phase is reached and to switch off the picocell if the safe flying phase is not reached, and
wherein the aircraft further comprises at least one display unit connected to the flight control device, wherein the flight control device is adapted to control the at least one display unit to:
activate clearance signs clearing use of the at least one mobile station if the safe flying phase is reached and the communications connection has been established between the base station and the terrestrial communications network, and
activate prohibition signs prohibiting use of the at least one mobile station if the safe flying phase is not reached.
5. The aircraft according to claim 4 wherein several picocells are set up on board.
6. A method for operating a picocell in an aircraft for the wireless transmission of data between at least a mobile station and a base station in the aircraft wherein a communications connection between the at least one mobile station in the aircraft and a subscriber in a terrestrial communications network is established via the base station, the method comprising:
checking by a flight control device whether a safe flying phase is reached, and
automatically switching on the base station by the flight control device when the safe flying phase is reached, and
automatically switching off the base station by the flight control device and activating a prohibition sign by the flight control device, when the safe flying phase is not reached,
wherein clearance signs are activated after the communications connection has been established between the base station and the terrestrial communications network.
