Definitions
- the invention relates to a method and an arrangement for power control for radio communication within an airworthy device according to the preamble of claim 1 or according to the preamble of claim 12.
- These spatial areas include, for example, sensitive areas in hospitals in which it would be possible to influence vital device functions by radio wave propagation or by selected transmission powers when carrying out radio communication.
- radio communication terminals used in the aircraft interior in order to establish a connection to an on-board central office.
- the central office then establishes a connection of the radio communication terminal of a subscriber to the outside world via a radio system of the aircraft.
- the aircraft operator console can for example be configured as a base station of a radio communications system to allow use of his own private business or used in flight Funkkommunikationsendgerats ⁇ convincing the participants.
- a base station ver ⁇ applies in this case standardized Funkubertragungsressourcen and Funkubertragungsvon, interference from terrestrial radio communication systems when crossing must be avoided. These disturbances are measurable, in particular, at altitudes below 3000 meters.
- a radio communication terminal can set up a radio connection to a terrestrial radio network, for example at an altitude of less than 3000 meters, without having to use the onboard base station or central station. In doing so, the radio communication terminal will transmit at a very high or maximum transmission power level to bridge the distance to the terrestrial base station, which may interfere with aircraft equipment, especially during takeoff or landing.
- Radiocommunication send fall and feeds the on-board base station, on the one hand radio links between the Funkkommuni- cation send fall in flight interior and allow a therefor see ⁇ NEN-board central office or on-board base station and to On the other hand, to avoid or minimize interference from terrestrial radio communication networks.
- an increase in the transmission power of the radio communication terminals and the aircraft base station in the aircraft interior is advantageous in order to ensure a more robust voice or data transmission or to increase the throughput in data services. Therefore, it is the object of the present invention to provide a method and an arrangement for power control for radio communication in the interior of an airworthy device, with the radio links with a designated central office while avoiding or reducing disturbances are possible and with the one possible high robustness of the radio communication or the highest possible data throughput is ensured.
- the radio communication between a central unit of the airworthy device and a radio communication terminal takes place.
- an adjustment of the transmission power for radio communication is controlled by the central unit.
- the transmission power is adjusted as a function of the flying height of the airworthy device.
- a transmit power is "transmit power" for a connection called uplink UL from a radio communication terminal MS to a central unit BTS and a transmission power "transmit power" for a connection referred to as downlink DL from the central unit BTS to the radio communication terminal MS applied.
- the central unit BTS is designed as a base station, while the radio communication terminal MS is designed as a mobile subscriber terminal.
- an aircraft is considered an “airworthy device”.
- Transmitting power is referred to as “minimum TX power” and hold during the referred to as “minimum altitude” flying height ⁇ hold.
- an upper limit of the transmission powers aircraft-specific defined, which may not be exceeded.
