MOBILE TELEKOMMUNIKATIONSVORRICHTUNG ZUR UNTERSTÜTZUNG ORTSABHÄNGIGER FUNKFREQUENZEN UND ÜBERTRAGUNGSVERFAHREN.MOBILE TELECOMMUNICATION DEVICE FOR SUPPORTING LOCATION-BASED RADIO FREQUENCIES AND TRANSMISSION METHODS.
5 In herkömmlichen Systemen zur drahtlosen Nachrichtenübertragung kommunizieren mobile Teilnehmerstationen gewöhnlich über stationäre Infrastruktureinrichtungen. Davon abweichend sind nun Satellitensysteme geplant oder im Aufbau, bei denen die Infrastruktur, also die Basisstationen durch Satelliten rea- 0 lisiert werden, die aus verschiedenen Gründen nicht geosta- tionär sind, sondern in relativ geringer Höhe die Erde umkreisen und dabei ihren Ort relativ zur Erdoberfläche laufend ändern.5 In conventional wireless communication systems, mobile subscriber stations usually communicate via stationary infrastructure facilities. Deviating from this, satellite systems are now planned or under construction, in which the infrastructure, ie the base stations, are implemented by satellites, which for various reasons are not geostationary, but orbit around the earth at a relatively low altitude and thereby their location relative to Change the surface of the earth continuously.
5 Im Laufe ihrer Bewegung um den Erdball werden diese mobilen Telekommunikationsvorrichtungen nacheinander die Territorien unterschiedlicher Staaten überfliegen, in denen unterschiedliche Vorschriften zur Nutzung von Frequenzen oder von Übertragungsprotokollen gelten. Der Erfindung liegt daher die 0 Aufgabe zugrunde eine technische Lehre anzugeben, mit der die Beachtung unterschiedlicher örtlicher und eventuell zeitlich sich ändernder Vorschriften zur Teleko munkation ermöglicht wird. Diese Aufgabe wird durch die Gegenstände der vorliegenden Patentansprüche gelöst. Dabei wird mit einer Einrichtung 5 zur Übertragung von Nachrichten an eine Vielzahl von Teilnehmerstationen über mehrere Funkfrequenzen oder mit Hilfe verschiedener Übertragungsverfahren und einer Einrichtung zur Auswertung wenigstens eines von der Position der Telekommunikationsvorrichtung abhängigen Steuersignals zur Auswahl oder 0 Änderung der von der Telekommunikationsvorrichtung benutzten Funkfrequenzen oder Übertragungsverfahren gewährleistet, daß die jeweils geltenden Vorschriften beachtet werden.5 As they move around the world, these mobile telecommunications devices will successively fly across the territories of different countries, where different regulations on the use of frequencies or transmission protocols apply. The invention is therefore based on the 0 object of specifying a technical teaching with which the observance of different local and possibly temporally changing regulations for telecommunications is enabled. This object is solved by the subject matter of the present claims. In this case, 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.
Durch die Erfindung wird also eine sehr weitgehende, zeitlich 5 optimale Anpassung der mobilen Infrastruktureinrichtungen an eine Vielzahl von nationalen Funkvorschriften ermöglicht, die eine bessere Ausnutzung von Ubertragungsressourcen erlaubt als die Verwendung global freigegebener Übertragungsressourcen. Satelliten sind natürlich nicht die einzigen vorstellbaren mobilen Telekommunikationsemrichtungen im Sinne der vorliegenden Erfindung. Naturlich können auch mobile Vorrichtungen auf Seeschiffen oder als Nutzlast von Luftschiffen und ähnliche mobile Telekom unikationsvorrichtungen im Sinne der vorliegenden Erfindung zum Einsatz kommen.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. Of course, satellites are not the only conceivable mobile telecommunication devices in the sense of the present invention. Of course, 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.

Diese vorteilhafte Ausgestaltung der Er¬ findung tragt damit dem Umstand, daß ein satellitengestutztes Telekommunikationssystem häufig gleichzeitig die Territorien mehrerer Staaten berührt, m besonders einfacher und robuster Weise Rechnung, indem geeignete Funkeinrichtungen für unterschiedliche Staaten vorgesehen werden können.Control signals. 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.
Eine weitere bevorzugte Ausfuhrungsform der Erfindung sieht vor, daß die Vorrichtung mit Mitteln zur Bestimmung der Posi- tion der Vorrichtung und Mitteln zur Erzeugung eines Steuersignals in Abhängigkeit von der momentanen Position ausgerüstet ist. Dies hat den Vorteil, daß keine spezielle terrestrische Infrastruktur zur Realisierung der Erfindung geschaffen werden muß.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.
Im folgenden wird die Erfindung mit Hilfe bevorzugter Ausfuh- rungsbeispiele und mit Hilfe von Figuren beschrieben.The invention is described below with the aid of preferred exemplary embodiments and with the aid of figures.
Figur 1 zeigt eine schematische Darstellung des Zusammenwir- kens einer erfmdungsgemaßen Vorrichtung mit einer terrestri- sehen Infrastruktur zur Steuerung der Telekommunikationsvorrichtung .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.
Figur 2 zeigt schematisch eine bevorzugte Ausfuhrungsform der erfindungsgemäßen Telekommunikationsvorrichtung mit mehreren Funkeinrichtungen .Figure 2 shows schematically a preferred embodiment of the telecommunication device according to the invention with several radio devices.
Mit Hilfe von Figur 1 wird deutlich, wie eine mobile Telekommunikationsvorrichtung 11 (Satellit) beim Überflug eines Grenzgebietes zwischen zwei örtlich begrenzten Mobilfunkin¬ frastrukturen 12, 13, durch ein Steuersignal 14 zur Auswahl oder Änderung der von der Telekommunikationsvorrichtung benutzten Funkfrequenzen oder Übertragungsverfahren veranlaßt werden kann. Das Steuersignal kann dabei direkt von terre- strischen 15 (Funkbake) oder anderen stationären Vorrichtungen (z.B. geostationäre Satelliten, etc.) ausgesandt werden, oder es kann durch eine Einrichtung zur Positionsbestimmung 16 in der Telekommunikationsvorrichtung selbst erzeugt wer¬ den. Befindet sich die Telekommunikationsvorrichtung 11 also im Sendebereich einer Funkbake 15, wird selbständig eine Reaktion in der Telekommunikationsvorrichtung, also z.B. ein Frequenz- oder Betriebsartwechsel veranlaßt.With the aid of Figure 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.
Auf diese Weise kann die mobile Telekommunikationsvorrichtung sich optimal auf örtliche oder zeitlich definierte Vorschriften zur Frequenzbelegung oder zur Nutzung von Übertragungsverfahren einstellen. Es ist z.B. möglich, dezentral Satellitenverbindungen zu beeinflussen; so könnte z.B. in Krisenherden für bestimmte Benutzergruppen die Benutzung eines Satelliten gesperrt werden.In this way, 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.
Die erfindungsgemäße Vorrichtung enthält also typischerweise eine steuerbare Funkeinrichtung oder mehrere solche Funkein¬ richtungen, die von einer programmierbaren Steuerung ein- und ausgeschaltet werden kann bzw. können. Die Information dar- über, wann dies geschehen soll, wird aus einem Steuersignal abgeleitet. Dieses Signal stammt von einer äußeren Vorrichtung oder wird im der mobilen Telkommuniaktionseinrichtung von Positionsdaten abgeleitet, die z.B. aus einem GPS (global positioning System) System stammen können.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.
Es ist vorteilhaft, wenn mehrere Funkteile 17, 18 oder ein auf mehrere Frequenzen - gegebenenfalls unterschieden nach Up- oder Down-Link - oder Betriebsarten umschaltbares Funk- teil in die Teleokommunikationsvorrichtung integriert wird. Hierbei können die Informationstabelle bzw. Algorithmen, die den Zusammenhang zwischen momentaner Position und der entsprechenden Betriebsart der Funkteile herstellen, auch von einer zentralen Kontrollstation geändert und so an sich än- dernde Vorschriften angepaßt werden.It is advantageous if 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. Here, 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.
In einer solchen mobilen Telekommunikationsvorrichtung ist demnach eine Speichereinrichtung für solche Tabellen (Datensätze) und eine Prozessoreinrichtung 19 zur Verarbei- tung und Anpassung dieser gespeicherten Daten vorzusehen. In such a mobile telecommunication device, 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.
