Description

MOBILTELEFON MIT ZUSÄTZLICHEN FUNKTIONEN MOBILE PHONE WITH ADDITIONAL FUNCTIONS
Beschreibung:Description:
Mobiltelefone sind durch einen Akku betriebene, im MHz- oder GHz-Bereich arbeitende Funktelefone in der Größe eines herkömmlichen Telefonhόrers. Sie stehen entweder als "Handy" mit einer terrestrischen Relaisstation oder einem Satelliten oder als "schnurloses Telefon" mit einer Reichweite von typisch einigen hundert Metern mit einer Basisstation in Verbindung, welche an ein Fernsprechnetz angeschlossen ist. Aus dem DE 91 09 141 U1 ist bereits ein Mobiltelefon bekannt, welches als Mobilteil eines Autoradios ausgebildet ist. Zu diesem Zweck enthält es zusätzlich zu den üblichen Bedientasten eines Telefons noch einige Bedientasten für das Bedienen des Autoradios, ein alphanumerisches Anzeigefeld für Frequenz- bzw. Senderanzeigen und einen Steckverbinder zum Verbin- den mit dem fest eingebauten Teil des Autoradios. Ist das Mobiltelefon mittels des Steckverbinders mit dem fest eingebauten Teil des Autoradios verbunden, dann kann dieses bedient werden. Zum Telefonieren zieht man das Mobiltelefon vom fest eingebauten Teil des Autoradios ab. Solange das Mobiitelefon abgezogen ist, kann man telefonieren, aber nicht das Autoradio bedienen. Nimmt man das Mobiltelefon mit, wenn man das Automobil abstellt, dann ist das Autoradio zugleich gegen Diebstahl gesichert, weil ohne das Bedienteil niemand etwas damit anfangen kann.Mobile phones are battery-operated, working in the MHz or GHz range, the size of a conventional telephone handset. They are connected either as a "cell phone" with a terrestrial relay station or a satellite or as a "cordless phone" with a range of typically a few hundred meters to a base station which is connected to a telephone network. From DE 91 09 141 U1 a mobile phone is already known, which is designed as a handset of a car radio. For this purpose, in addition to the usual control buttons on a telephone, it also contains a few control buttons for operating the car radio, an alphanumeric display field for frequency or transmitter displays and a connector for connecting to the permanently installed part of the car radio. If the mobile phone is connected to the built-in part of the car radio using the connector, this can be operated. To make a phone call, pull the mobile phone off the permanently installed part of the car radio. As long as the mobile phone is disconnected, you can make calls, but you cannot operate the car radio. Taking the mobile phone with you when you park the car, the car radio is also secured against theft, because without the control panel nobody can do anything with it.
Die vorliegende, im Anspruch 1 angegebene Erfindung erweitert den Anwβn- dungsbereich von Mobiltelefonen demgegenüber ganz erheblich, indem sie vorschlägt, im Mobiltelefon einen Infrarotsender vorzusehen, welcher durch die bei Mobiltelefonen ohnehin vorgesehenen Bedientasten und/oder durch zusätzliche Bedientasten steuerbar ist. Zu diesem Zweck enthält das Mobiltelefon zweckmäßigerweise eine Steuerschaltung, welche das Betätigen der Bedientasten in eine vom Infrarotsender zu übertragende Information wandelt. Bei Bedientasten, die nur für das Bedienen des Infrarotsenders vorgesehen sind, kann das unmittelbar geschehen, bei Bedientasten, die auch für das Bedienen des Telefons vorgesehen sind, erst nach Umschalten der Betriebsart des Mobiltelefons vom Telefonbetrieb auf den Infrarotsendebetrieb.The present invention specified in claim 1, on the other hand, extends the application range of mobile telephones considerably by proposing to provide an infrared transmitter in the mobile telephone which can be controlled by the control buttons provided in any case for mobile telephones and / or by additional control buttons. For this purpose, the mobile phone expediently contains a control circuit which converts the actuation of the control buttons into information to be transmitted by the infrared transmitter. With control buttons that are only intended for operating the infrared transmitter, this can happen immediately, with control buttons that are also provided for operating the telephone, only after switching the operating mode of the mobile phone from telephone mode to infrared transmission mode.
Der Infrarotsender und sein Betrieb können so ausgewählt sein, wie es bei herkömmlichen Fernbedienungsgeräten der Fall ist, wobei als Steuerschaltung für den Infrarotsender vorzugsweise ein Mikroprozessor vorgesehen ist, welcher zugleich die Telefonfunktionen steuert.The infrared transmitter and its operation can be selected as is the case with conventional remote control devices, wherein a microprocessor is preferably provided as the control circuit for the infrared transmitter, which also controls the telephone functions.
Auf diese Weise kann das Mobiltelefon als Fernbedienung für alle möglichen Geräte und Einrichtungen verwendet werden, welche bisher noch durch individuelle Infrarot-Fembedienungseinheiten bedient werden.In this way, the mobile phone can be used as a remote control for all possible devices and facilities that have so far been operated by individual infrared remote control units.
Heutige Mobiltelefone sind vielfach nicht größer als herkömmliche Fernbedienungseinheiten. Da die Größe im wesentlichen durch das Tastenfeld, das alphanumerische Anzeigefeld und den Akku bestimmt wird, wird das Mobiltelefon da- durch, daß es erfindungsgemäß zusätzlich die Aufgabe einer Fernbedienung übernimmt, in seinen Außenabmessungen nicht notwendigerweise größer. Da heutige Mobiltelefone ohnehin schon mit Hilfe einer Menüführung bedient werden, ist es leicht möglich, die Menüs um solche für die Betätigung der Fembedienung zu erweitern, und das macht es möglich, den für die Telefonbedienung vorgesehenen Tasten durch die Auswahl eines Menüs "Fernbedienung" besondere Funktionen im Rahmen der Fembedienung zuzuweisen, so daß man, um die Fembedienung zu verwirklichen, keine oder nur wenige zusätzliche Bedientasten benötigt.Today's mobile phones are often no larger than conventional remote control units. Since the size is essentially determined by the keypad, the alphanumeric display field and the battery, the external dimensions of the mobile phone do not necessarily increase due to the fact that it additionally takes on the function of a remote control. Since today's cell phones are already operated with the help of a menu become, it is easily possible to expand the menus to include those for the operation of the remote control, and this makes it possible to assign special functions within the range of the remote control to the keys provided for the telephone control by selecting a menu "remote control", so that one In order to implement the remote control, no or only a few additional control buttons are required.
Heutige Mobiltelefone werden mittels eines Mikroprozessors gesteuert, dessen Rechen-, Steuer- und Speicherkapazität durch die Telefonfunktionen nicht ausgelastet ist, sondern ohne weiteres noch für die Steuerung der Fembedienungs- funktionen herangezogen werden kann, was komfortable Fembedienungen mit vielen eingebbaren Voreinstellungen ermöglicht. Darüberhinaus ist es nicht nur möglich, das Mobiltelefon zur Fembedienung eines einzigen Gerätes heranzuziehen, sondern zur Fernbedienung aller möglichen Geräte, die sich zur Fembedienung eignen und/oder heute schon die Möglichkeit einer Infrarot-Fembedienung haben. Das Gerät, welches im konkreten Fall fernbedient werden soll, kann mit Hilfe einer einfachen Menüführung ausgewählt und aufgerufen werden.Today's mobile phones are controlled by means of a microprocessor, the computing, control and storage capacity of which is not fully utilized by the telephone functions, but can also be used for the remote control of the remote control functions, which enables convenient remote controls with many predefined settings. In addition, it is not only possible to use the mobile phone for remote control of a single device, but for remote control of all possible devices that are suitable for remote control and / or already have the option of infrared remote control. The device, which is to be operated remotely in the specific case, can be selected and called up using simple menu navigation.
Zum Betreiben eines Handys wird eine freigeschaltete Codekarte benötigt. Fehlt die Codekarte oder ist sie nicht freigeschaltet, kann nicht telefoniert werden. Um in diesem Fall dennoch den Infrarotsender und - wenn vorhanden - den Infraro- tempfänger benutzen zu können, ist die den Code der Codekarte auswertende Schaltung des Handys vorzugsweise so ausgebildet, daß sie lediglich die Telefonfunktion freischaltet oder sperrt, nicht aber die Betriebsbereitschaft des Infrarotsenders und -empfängers. Das hat den zusätzlichen Vorteil, daß man das Handy zum Zwecke der Fembedienung an eine andere Person geben und durch Entnehmen der Codekarte verhindern kann, daß die Person das Handy unerwünscht zum Telefonieren nutzt.An activated code card is required to operate a cell phone. If the code card is missing or is not activated, calls cannot be made. In order to be able to use the infrared transmitter and - if available - the infrared receiver in this case, the circuit of the cell phone evaluating the code of the code card is preferably designed such that it only enables or disables the telephone function, but not the operational readiness of the infrared transmitter and -receiver. This has the additional advantage that the cell phone can be given to another person for the purpose of remote control and can be prevented by removing the code card that the person can use the cell phone to make calls.
Durch die vielfältigen Möglichkeiten, die ein erfindungsgemäß weitergebildetes Mobiltelefon bietet, wird es zu einer persönlichen Schlüsselkomponente seines Eigentümers, weil es derart ausgerüstet in nahezu allen Lebensbereichen Zugang zu einer Vielzahl von Geräten, Einrichtungen, und Funktionen bietet, die nach heutigem Stand der Technik nur mit individuellen Infrarot-Fembedienungs- einheiten bewältigt werden können, die auch nicht zugleich die Möglichkeit zum Telefonieren bieten.Due to the diverse possibilities that a mobile phone developed according to the invention offers, it becomes a personal key component of its Owner, because equipped in this way in almost all areas of life it offers access to a multitude of devices, facilities and functions which, according to the current state of the art, can only be managed with individual infrared remote control units, which also do not offer the option of making calls .
Aus der Vielzahl der möglichen Anwendungen seien die folgenden besonders hervorgehoben:The following are particularly noteworthy from the multitude of possible applications:
Das Mobiltelefon kann zur Fernbedienung von Fernsehempfangsgeräten, von Fernsehaufzeichnungs und Wiedergabegeräten (Videorecordern und Abspielge- raten für Bildplatten), von Tonrundfunkempfangsgeräten, von Tonaufzeichnungsund Wiedergabegeräten (Magnetbandgeräte, CD-Abspielgeräte, HiFi-Anlagen), welche heute schon weitgehend mit Einrichtungen zur Infrarot-Fernbedienung ausgerüstet sind, verwendet werden.The mobile phone can be used for remote control of television receivers, television recorders and playback devices (video recorders and playback devices for video discs), radio broadcasting receivers, sound recording and playback devices (magnetic tape devices, CD players, hi-fi systems), which are today largely equipped with devices for infrared remote control are equipped.
Elektronische Schließeinrichtungen, die mit einer Infrarot-Fernbedienung betätigt werden, finden zunehmend Verbreitung bei Fahrzeugen und Gebäuden, z.B. Fernbedienungen für Garagentore. Auch dafür eignet sich ein erfindungsgemäß ausgerüstetes Mobiltelefon hervorragend. Es könnte auch eingesetzt werden als Ausweis in elektronischen Zugangskontrollsystemen in Dienstgebäuden oder an Maschinen, indem dem Mobiltelefon ein persönlicher Zugangscode eingespei- chert wird, welcher auf Knopfdruck ausgesendet und von einem Infrarotempfänger des Zugangskontrollsystems empfangen und ausgewertet werden kann.Electronic locking devices that are operated with an infrared remote control are becoming increasingly widespread in vehicles and buildings, e.g. Remote controls for garage doors. A mobile telephone equipped according to the invention is also outstandingly suitable for this. It could also be used as identification in electronic access control systems in office buildings or on machines, by storing a personal access code on the mobile phone, which can be transmitted at the push of a button and received and evaluated by an infrared receiver of the access control system.
Für eine infrarotbedienbare Haustürschließanlage kann ein erfindungsgemäß ausgerüstetes Mobiltelefoπ als Schlüssel verwendet werden oder auch zur Fembedienung von Computern.For an infrared door lock system, a mobile phone equipped according to the invention can be used as a key or for remote control of computers.
In einem Kraftfahrzeug schließlich läßt sich ein erfindungsgemäß ausgerüstetes Mobiltelefon nicht nur zum Aufschließen der Tür durch Fernbedienung, sondern auch als elektronischer Zündschlüssel, als Diebstahisicherung für das Fahrzeug (das Starten ist nur nach Eingabe eines individuellen Codes möglich), als Bedienteil für das Autoradio und auch als Diebstahlsicherung für das Autoradio verwendet werden. Es kann als Bedienteil für das Autoradio verwendet werden, oh- ne mit diesem über einen Stecker verbunden sein zu müssen, wie es in dem DE-91 09 141 U1 vorgesehen ist. Es kann deshalb auch dazu dienen, das Autoradio von den Rücksitzen her zu bedienen, und auch der Beifahrer kann mit seiner Hilfe das Autoradio bequemer bedienen, weil er die Bedientasten besser im Griff und das Anzeigefeld besser im Blick hat als bei einem fest eingebauten Be- dienteil. Das Autoradio kann dadurch gegen Diebstahl geschützt sein, daß es nur mit einer individuellen Kennung, welche dem Mobiltelefon einprogrammiert ist, betrieben werden kann. Durch die drahtlose Kupplung zwischen Mobiltelefon und Autoradio ist es darüberhinaus möglich, die Außenantenne oder Scheibenantenne des Fahrzeuges, welche für das Autoradio vorgesehen ist, auch für den Sen- de- und Empfangsbetrieb des Mobiltelefoπs zu nutzen. Das Mobiltelefon könnte sogar zur Sprachsteuerung des Autoradios oder einer im Fahrzeug eingebauten HiFi-Anlage benutzt werden. Über eine Infrarot-Schnittstelle könnten Faxmitteilungen von und zu einem Notebook-Computer geschickt werden.Finally, in a motor vehicle, a cell phone equipped according to the invention can be used not only to unlock the door by remote control, but also can also be used as an electronic ignition key, as an anti-theft device for the vehicle (starting is only possible after entering an individual code), as a control unit for the car radio and also as an anti-theft device for the car radio. It can be used as a control unit for the car radio without having to be connected to it via a plug, as is provided in DE-91 09 141 U1. It can therefore also be used to operate the car radio from the rear seats, and the passenger can also use it to operate the car radio more comfortably because he has a better grip on the control buttons and a better view of the display panel than with a built-in control serving part. The car radio can be protected against theft in that it can only be operated with an individual identifier which is programmed into the mobile phone. The wireless coupling between the mobile phone and the car radio also makes it possible to use the vehicle's external antenna or windshield antenna, which is provided for the car radio, for transmitting and receiving the mobile phone. The mobile phone could even be used for voice control of the car radio or a hi-fi system installed in the vehicle. Fax messages could be sent to and from a notebook computer via an infrared interface.
Voice-e-Mails könnten über eine geeignete Codier-/Decodiereinhchtung direkt vom Mikrofon über das Mobiltelefon verschickt und umgekehrt aus einer Mailbox an das Mobiltelefon übertragen werdenVoice e-mails could be sent via a suitable coding / decoding device directly from the microphone to the cell phone and vice versa from a mailbox to the cell phone
Nachrichten aller Art könnten auf individuellen Abruf über das Mobiltelefon ins Auto übertragen, durch die Infrarotverbindung über das eingebaute Autoradio laut wiedergegeben werden.Messages of all kinds could be transmitted to the car on individual request via the mobile phone and played back loudly via the infrared connection via the built-in car radio.
Vorzugsweise hat das erfindungsgemäße Mobiltelefon nicht nur einen Infrarotsender, sondern auch einen Infrarotempfänger, so daß es Nachrichten über die Infrarotverbindung nicht nur senden, sondern auch empfangen kann, um eine interaktive Kommunikation mit anderen Geräten zu ermöglichen. Das macht z.B. die Verwendung des Mobiltelefons als schnurloses Telefon möglich, wenn sich im selben Raum eine Basisstation des Telefons befindet, welche ebenfalls mit einem Infrarotsensor und -Empfänger ausgerüstet ist.Preferably, the mobile phone according to the invention not only has an infrared transmitter, but also an infrared receiver, so that it can not only send but also receive messages via the infrared connection in order to enable interactive communication with other devices. That does for example the mobile phone can be used as a cordless phone if there is a base station for the phone in the same room, which is also equipped with an infrared sensor and receiver.
