Definitions

• a device 5 for transmitting messages to a plurality of subscriber stations over a plurality of radio frequencies or with the aid of various transmission methods and a device for evaluating at least one control signal dependent on the position of the telecommunication device for selecting or changing the radio frequencies or transmission methods used by the telecommunication device ensures that the applicable regulations are observed.
• the invention therefore enables a very extensive, optimal temporal adaptation of the mobile infrastructure devices allows a variety of national radio regulations, which allows a better use of transmission resources than the use of globally released transmission resources.
• satellites are not the only conceivable mobile telecommunication devices in the sense of the present invention.
• mobile devices on seagoing ships or as payloads of airships and similar mobile telecommunications devices can also be used in the sense of the present invention.
• This advantageous embodiment of the invention ⁇ He carries with it the fact that a satellite telecommunications system truncated frequently the territories affected several states simultaneously, m very simple and robust way account by appropriate radio equipment can be provided for different countries.
• Another preferred embodiment of the invention provides that the device is equipped with means for determining the position of the device and means for generating a control signal as a function of the current position. This has the advantage that no special terrestrial infrastructure has to be created to implement the invention.
• FIG. 1 shows a schematic illustration of the interaction of a device according to the invention with a terrestrial see infrastructure to control the telecommunications device.
• Figure 2 shows schematically a preferred embodiment of the telecommunication device according to the invention with several radio devices.
• FIG. 1 illustrates how a mobile telecommunications device 11 (satellite) when flying over a border region between two localized Mobilfunkin ⁇ infrastructures 12, 13 may be occasioned by a control signal 14 for selecting or changing the radio frequencies used by the telecommunications apparatus or transmission method .
• the control signal may in this case directly by Terre- strischen 15 (EPIRB), or other stationary devices (for example, geostationary satellites, etc.) are transmitted, or it may itself generates the ⁇ by a device for determining the position 16 in the telecommunications apparatus. If the telecommunication device 11 is thus in the transmission range of a radio beacon 15, a reaction in the telecommunication device, for example a frequency or operating mode change, is automatically initiated.
• the mobile telecommunication device can adapt optimally to local or time-defined regulations for frequency allocation or for the use of transmission methods. It is e.g. possible to influence decentralized satellite connections; for example the use of a satellite can be blocked in trouble spots for certain user groups.
• the inventive device thus typically includes directions a controllable radio device or a plurality of such ⁇ Radio equipment, the one of a programmable controller and can be switched off or can.
• the information about when this should happen is derived from a control signal.
• This signal comes from an external device or is derived in the mobile telecommunication device from position data, which can originate, for example, from a GPS (global positioning system) system.
• a plurality of radio parts 17, 18 or a radio part which can be switched over to a plurality of frequencies - possibly differentiated according to uplink or downlink - or operating modes is integrated into the tele-communication device.
• the information table or algorithms that establish the connection between the current position and the corresponding operating mode of the radio parts can also be changed by a central control station and thus adapted to changing regulations.
• a storage device for such tables (data records) and a processor device 19 for processing and adapting this stored data are accordingly to be provided.
