Abstract

A paging receiver with a computing unit is proposed by means of which the transmitted status messages are visually and possibly also acoustically indicated. An input device (21) (keyboard) is provided by means of which at least one word, particularly a telephone number, can be allocated to each status message. When a status message is received, the associated word, instead of the number of the status message, is given to a visual display device (18). This also provides, in addition to better identification of the status message, the direct possibility of calling back by telephone. <IMAGE>

Description

Stand der TechnikState of the art

Die Erfindung betrifft einen Personenrufempfänger (Pagingempfänger) nach der Gattung des Hauptanspruchs.The invention relates to a pager (paging receiver) according to the preamble of the main claim.

Solche Empfänger sind bereits vielfach verbreitet und dienen dazu, einer Person eine einzige oder mehrere Informationen (Statusmeldungen) über den Funkweg durchzugeben. Die empfangende Person kann entsprechend einer vorher getroffenen Vereinbarung die verschiedenen Statusmeldungen verschiedenen Anrufern zuordnen und diese zum Beispiel über das Telefonnetz über den Zweck des Anrufs befragen. Aufwendigere Geräte, wie sie zum Beispiel in der Zeitschrift "Fortune", 28. Dezember 1981, Seite 67, beschrieben sind, beinhalten die Möglichkeit, vielstellige Nummern oder ganze Texte durchzugeben. Dies hat dann natürlich den Nachteil, daß der Funkkanal für längere Zeit belegt wird. Die moderneren Personenrufempfänger beinhalten gewöhnlich einen Mikroprozessor.Such receivers are already widely used and are used to provide a person with one or more pieces of information (status messages) via the radio path. The receiving person can assign the various status messages to different callers in accordance with a previously made agreement and ask them, for example via the telephone network, about the purpose of the call. More complex devices, as described, for example, in the magazine "Fortune", December 28, 1981, page 67, include the option of passing through multi-digit numbers or entire texts. This then of course has the disadvantage that the radio channel is occupied for a long time. The more modern pager usually include a microprocessor.

Wenn durch einen solchen Personenrufempfänger mehrere verschiedene Statusmeldungen empfangen werden können, ist es oft schwierig, sie untereinander zu unterscheiden. Selbst wenn dies ohne weiteres möglich wäre und eine Zuordnung zu einem bestimmten Anrufer erkannt wird, muß dennoch die Telefonnummer für den Rückruf aus dem Telefonbuch oder einem Notizbuch entnommen werden.When several different status messages can be received by such a pager, it is often difficult to distinguish between them. Even if this were easily possible and an assignment to a specific caller is recognized, the telephone number for the callback must still be taken from the telephone book or a notebook.

Vorteile der ErfindungAdvantages of the invention

Der erfindungsgemäße Personenrufempfänger mit den kennzeichnenden Merkmalen des Hauptanspruchs hat demgegenüber den Vorteil, daß der Benutzer des Personenrufempfängers jeder Statusmeldung zuvor schon Worte, insbesondere Telefonnummern, zuordnen kann, die dann anstelle der Nummer der Statusmeldung auf der Anzeigevorrichtung beim Empfang einer Statusmeldung erscheinen. Im Falle einer Telefonnummer und/oder gegebenenfalls des Namens des Anrufers oder seines Kurzzeichens kann dann ohne Schwierigkeit ein Rückruf erfolgen. Sowohl die Zuordnung als auch die weitere Information, wie zurückgerufen werden soll, sind dann unmittelbar gegeben. Dabei werden diese Zusatzinformationen ermöglicht, obwohl nur einfache Statusmeldungen über den Funkweg übertragen werden, die den Funkkanal nur sehr kurz beanspruchen.The paging receiver according to the invention with the characterizing features of the main claim has the advantage that the user of the paging receiver can already assign words, in particular telephone numbers, to each status message, which then appear instead of the number of the status message on the display device when a status message is received. In the case of a telephone number and / or possibly the name of the caller or his abbreviation, a callback can then be made without difficulty. Both the assignment and the further information on how to call back are then given immediately. This additional information is made possible, although only simple status messages are transmitted via the radio path that only occupy the radio channel for a very short time.

Durch die in den Unteransprüchen aufgeführten Maßnahmen sind vorteilhafte Weiterbildungen und Verbesserungen des im Hauptanspruch angegebenen Personenrufempfängers möglich.The measures listed in the subclaims enable advantageous further developments and improvements to the paging receiver specified in the main claim.

Beschreibung des AusführungsbeispielsDescription of the embodiment

Über eine Antenne 10 gelangen die empfangenen Funksignale in einen UHF- bzw. VHF-Teil 11, wo sie selektiv verstärkt werden. In einer nachgeschalteten Mischstufe 12 werden diesen Signalen die Signale eines Oszillators 13 zugeführt, so daß eine Zwischenfrequenz entsteht, die in einer ZF-Stufe 14 verstärkt wird. Im nachgeschalteten Diskriminator 15 erfolgt die Demodulation der datenkodierten Signale (FSK-Signale), die dann anschließend in einer Entscheidungsschaltung 16 in digitale Daten-Signale umgewandelt werden. In der nachgeschalteten Rechnereinheit 17, vorzugsweise einem Mikrorechner, erfolgt dann die Dekodierung dieser Daten-Signale und die Anzeige des dekodierten Werts. Diese Anzeige erfolgt-optisch auf einer Anzeigevorrichtung 18 und akustisch über einen Verstärker 19 und einen Lautsprecher 20. Der dekodierte Wert liegt als sogenannte Statusmeldung vor, wobei zum Beispiel zehn verschiedene Statusmeldungen durch zehn verschiedene Ziffern auf der Anzeigevorrichtung 18 darstellbar sind. Entsprechend werden vom Lautsprecher 20 zehn verschiedene Tonfolgen abgegeben, die die Bedienperson identifizieren muß. Die Tonfolgen werden dabei durch die Rechnereinheit 17 generiert. Diese Rechnereinheit 17 ist weiterhin einer Eingabevorrichtung 21 zugeordnet, die in der Darstellung als Tastatur mit 16 Tasten abgebildet ist.Via an antenna 10, the received radio signals reach a UHF or VHF part 11, where they are selectively amplified. In a downstream mixer stage 12, the signals of an oscillator 13 are fed to these signals, so that an intermediate frequency arises which is amplified in an IF stage 14. The data-coded signals (FSK signals) are demodulated in the downstream discriminator 15, which are then subsequently converted into digital data signals in a decision circuit 16. These data signals are then decoded and the decoded value is displayed in the downstream computer unit 17, preferably a microcomputer. This display takes place optically on a display device 18 and acoustically via an amplifier 19 and a loudspeaker 20. The decoded value is present as a so-called status message, with ten different status messages being able to be represented by ten different numbers on the display device 18, for example. Accordingly, ten different tone sequences are emitted by the loudspeaker 20, which the operator must identify. The tone sequences are generated by the computer unit 17. This computer unit 17 is also assigned to an input device 21, which is shown in the illustration as a keyboard with 16 keys.

In Fig. 2 ist das Gehäuse des Personenrufempfängers dargestellt, das im wesentlichen Scheckkartenformat aufweist. In diesem Gehäuse sind die in Fig. 1 dargestellten Blöcke untergebracht bzw. aufgebracht. Auf der Frontseite dieses Gehäuses sind die Anzeigevorrichtung 18 (Display), die Eingabevorrichtung 21 (Tastatur), der Lautsprecher 20 sowie eine Stummschalttaste 23 untergebracht.In Fig. 2 the housing of the pager is shown, which has essentially credit card format. The blocks shown in FIG. 1 are accommodated or applied in this housing. The display device 18 (display), the input device 21 (keyboard), the loudspeaker 20 and a mute button 23 are accommodated on the front of this housing.

Die Wirkungsweise des dargestellten Ausführungsbeispiels besteht darin, daß bei Ankunft eines Funksignals zunächst die enthaltene Statusmeldung auf der Anzeigevorrichtung 18 als Zahl angezeigt und gleichzeitig eine entsprechende Tonfolge über den Lautsprecher 20 abgegeben wird. Wird die Stummschalttaste 23 betätigt, so erfolgt zwar immer noch die optische Anzeige, jedoch wird diese akustisch unterdrückt, um zum Beispiel eine wichtige Konferenz nicht zu stören.The mode of operation of the exemplary embodiment shown is that when a radio signal arrives, the status message it contains is first displayed as a number on the display device 18 and, at the same time, a corresponding tone sequence is emitted via the loudspeaker 20. If the mute button 23 is actuated, the visual display is still carried out, but this is suppressed acoustically, for example in order not to disturb an important conference.

Durch die Eingabetastatur 21 kann nun jeder Statusmeldung eine ausführlichere Information zugeordnet werden. So wird beispielsweise der Statusmeldung Nr. 6 eine achtstellige Telefonnummer sowie ein zweistelliges Kurzzeichen des Inhabers dieser Telefonnummer zugeordnet. Dies kann zum Beispiel dadurch geschehen, daß nach Betätigung einer Eingabetaste der Eingabevorrichtung 21 die Taste 6, danach eine Gleichungstaste und schließlich die Telefonnummer und das Kurzzeichen eingetastet werden. Die Telefonnummer und das Kurzzeichen werden dann in einem Speicher der Rechnereinheit 17 abgelegt. Wird die entsprechende Statusmeldung empfangen, so werden über die Zahl 6 die entsprechenden Speicherzellen angesprochen und der Speicherinhalt anstelle der Zahl 6 auf die Anzeigevorrichtung 18 gegeben. Auf diese Weise erkennt der Angerufene unmittelbar, wer der Anrufer ist und über welche Telefonnummer er ihn erreichen kann. Natürlich können anstelle von Telefonnummern auch beliebige andere Informationen auf diese Weise den Statusmeldungen zugeordnet werden.The input keyboard 21 can now be used to assign more detailed information to each status message. For example, status message No. 6 is assigned an eight-digit telephone number and a two-digit abbreviation for the owner of this telephone number. This can be done, for example, by pressing key 6 after pressing an input key of input device 21, then an equation key and finally the telephone number and the abbreviation. The telephone number and the short sign are then stored in a memory of the computer unit 17. If the corresponding status message is received, the corresponding memory cells are addressed via the number 6 and the memory content is given to the display device 18 instead of the number 6. In this way, to recognize g erufene immediately who the caller is and what phone number he can reach him. Of course, instead of telephone numbers, any other information can be assigned to the status reports in this way.

Da der Personenrufempfänger mit der Eingabevorrichtung 21 und der Anzeigevorrichtung 18 bereits alle Hardware-Elemente enthält, die zum Ausführen von Rechenoperationen notwendig sind, ist es besonders vorteilhaft, der Rechnereinheit 17 auch arithmetische Funktionen zuzuordnen. Auf diese Weise kann dann ohne zusätzlichen Hardware-Aufwand der Personenrufempfänger auch als Taschenrechner verwendet werden.Since the pager with the input device 21 and the display device 18 already contains all the hardware elements required for performing arithmetic operations are necessary, it is particularly advantageous to also assign arithmetic functions to the computer unit 17. In this way, the pager can then be used as a calculator without additional hardware.

In der Rechnereinheit 17 können natürlich noch weitere Funktionen und Kombinationen von Funktionen realisiert werden, zum Beispiel Zeitfunktionen und individuell programmierbare Stummschaltfunktionen.Further functions and combinations of functions can of course also be implemented in the computer unit 17, for example time functions and individually programmable muting functions.
