- Reasons for this may be that the user of the cordless or mobile telephone has either forgotten to switch off the terminal or that he also wants to be reachable in the situations mentioned above.
- This is usually very uncomfortable for the owner of the cordless or mobile phone, especially if he lets the cordless or mobile phone ring until he has left the room. Nevertheless, it can happen that he loses the call if the caller does not have enough patience to wait.
- Another disadvantage is that others can overhear the conversation if he decides to answer the call immediately. In any case, there is a disturbance or distraction for everyone present.

MOBILES TELEFONENDGERÄTMOBILE TELEPHONE DEVICE
Es kommt immer wieder vor, daß in Besprechungen, während Vorträgen oder in Restaurants schnurlose bzw. mobile Telefone klingeln. Gründe dafür können sein, daß der Benutzer des schnurlosen bzw. mobilen Telefons entweder vergessen hat das Endgerät auszuschalten, oder daß er auch in den oben ange- sprochenen Situationen erreichbar sein möchte. Im ersten Fall könnte er die störenden Begleiterscheinungen einfach dadurch verhindern, daß er das Gerät abschaltet; im zweiten Fall muß er störende Rufsignale in Kauf nehmen, um erreichbar zu sein. Dies ist für den Besitzer des schnurlosen bzw. mobilen Tele- fons meistens recht unangenehm, besonders wenn er das schnurlose bzw. mobile Telefon so lange klingeln läßt, bis er den Raum verlassen hat. Trotzdem kann es ihm passieren, daß er das Gespräch verliert, falls der Anrufende nicht genügend Geduld zum Warten aufbringt. Ein weiterer Nachteil ist, daß an- dere das Gespräch mithören können, falls er sich entschließt das Gespräch sofort entgegen zu nehmen. In jedem Fall gibt es für alle anwesenden Personen eine Störung oder Ablenkung.It often happens that cordless or mobile telephones ring in meetings, during lectures or in restaurants. Reasons for this may be that the user of the cordless or mobile telephone has either forgotten to switch off the terminal or that he also wants to be reachable in the situations mentioned above. In the first case, he could simply prevent the disturbing side effects by switching off the device; in the second case, he has to put up with disturbing call signals in order to be reachable. This is usually very uncomfortable for the owner of the cordless or mobile phone, especially if he lets the cordless or mobile phone ring until he has left the room. Nevertheless, it can happen that he loses the call if the caller does not have enough patience to wait. Another disadvantage is that others can overhear the conversation if he decides to answer the call immediately. In any case, there is a disturbance or distraction for everyone present.
Die hier genannten Probleme sind grundsätzlich nicht auf schnurlose oder mobile Telefone beschränkt. Auch bei anderen Telefonendgeräten kann in bestimmten Situationen ein lang andauerndes akustisches Rufsignal unerwünscht sein, obwohl der Benutzer des Endgerätes grundsätzlich mit Hilfe akustischer Systemmeldungen auf einen vorliegenden Anruf hingewiesen wer- den möchte.The problems mentioned here are basically not limited to cordless or mobile phones. In certain situations, a long-lasting acoustic call signal may also be undesirable in other telephone terminals, although the user of the terminal generally wishes to be alerted to an existing call with the aid of acoustic system messages.
Der Erfindung liegt daher die Aufgabe zugrunde, ein Telefonendgerät anzugeben, mit welchem die genannten Nachteile nach Möglichkeit vermieden werden können, ohne daß der Vorteil der akustischen Meldung von ankommenden Rufen verloren wird. Diese Aufgabe wird erfindungsgemäß mit Hilfe eines Telefonendgerätes mit Merkmalen nach Anspruch 1 gelöst .The invention is therefore based on the object of specifying a telephone terminal with which the disadvantages mentioned can be avoided as far as possible without the advantage of the acoustic signaling of incoming calls being lost. This object is achieved with the help of a telephone terminal with features according to claim 1.
Dieses Telefonendgerät besitzt eine Einrichtung zur Ausgabe akustischer Systemmeldungen, insbesondere zur Ausgabe von Rufsignalen an den Benutzer des Endgerätes, eine Einrichtung zur Speicherung von Sprachsignalen und ein Bedienelement, dessen Betätigung im Falle eines ankommenden Rufes folgendes bewirkt : a) die Verhinderung oder sofortige Beendigung der Ausgabe akustischer Systemmeldungen an den Benutzer des Endgerätes, b) die Annahme des ankommenden Rufes ohne Übertragung akustischer Signale, insbesondere Sprachsignale, zwischen Anrufer und Benutzer und c) die Ausgabe eines gespeicherten Sprachsignals an den Anrufer, mit welchem dieser zum Halten der Leitung aufgefordert wird.This telephone terminal has a device for outputting acoustic system messages, in particular for outputting call signals to the user of the terminal, a device for storing voice signals and an operating element, the actuation of which, in the event of an incoming call, does the following: a) preventing or immediately ending the output acoustic system messages to the user of the terminal, b) accepting the incoming call without transmission of acoustic signals, in particular voice signals, between the caller and user and c) outputting a stored voice signal to the caller, with which the caller is asked to hold the line.
Durch Betätigung eines Bedienelements wird eine ankommendes Gespräch zwar angenommen, zunächst aber keine Sprechverbindung mit dem Anrufer hergestellt. Statt dessen wird ein gespeicherter Text angesagt, mit dem der Anrufer aufgefordert wird, die Leitung zu halten. Hierdurch können störende Rufsignale schnell unterdrückt werden, ohne die Gesprächsannahme unnötig zu verzögern.By actuating an operating element, an incoming call is accepted, but initially no speech connection is established with the caller. Instead, a stored text is announced, which prompts the caller to put the line on hold. In this way, disruptive call signals can be suppressed quickly without unnecessarily delaying the call acceptance.
Das erfindungsgemäße Telefonendgerät gibt seinem Benutzer also die Möglichkeit, sich mit Hilfe akustischer Systemmel- dungen auf einen ankommenden Anruf hinweisen zu lassen, und diese akustischen Systemmeldungen durch Betätigung eines Bedienelementes sofort zu unterdrücken. Dabei wird der ankommende Ruf angenommen und es wird ein gespeichertes Sprachsignal an den Anrufer ausgegeben, mit welchem dieser zum Halten der Leitung aufgefordert wird. Es kann also nicht vorkommen, daß der Benutzer ein Gespräch verliert, weil der Anrufer zu lange auf eine Gesprächsannahme warten muß. Gleichzeitig ist durch das Fehlen einer Übertragung akustischer Signale zwischen Anrufer und Benutzer sichergestellt, daß ein Mithören von Gesprächen in dem Raum in dem sich das Telefonendgerät befindet durch den Anrufer ausgeschlossen ist. Weil ferner kein Gespräch zwischen Anrufer und Benutzer des Endgerätes stattfindet, kann auch ein solches Gespräch von Personen, die sich in einem Raum mit dem Benutzer des Endgerätε befinden, nicht abgehört werden.The telephone terminal according to the invention thus gives its user the option of being alerted to an incoming call using acoustic system messages and of suppressing these acoustic system messages immediately by actuating an operating element. The incoming call is accepted and a stored voice signal is output to the caller, with which the caller is asked to hold the line. So it cannot happen that the user loses a call because the caller has to wait too long to answer the call. At the same time the absence of a transmission of acoustic signals between the caller and the user ensures that eavesdropping on conversations in the room in which the telephone terminal is located is excluded by the caller. Furthermore, because there is no conversation between the caller and the user of the terminal, such a conversation cannot be overheard by people who are in a room with the user of the terminal.
Vorteilhafte Weiterbildungen der Erfindung sind Gegenstand untergeordneter Patentansprüche .Advantageous developments of the invention are the subject of subordinate claims.
Im folgenden wird die Erfindung anhand bevorzugter Ausführungsbeispiele näher beschrieben.The invention is described in more detail below on the basis of preferred exemplary embodiments.
Ausgangspunkt für die Realisierung der vorliegenden Erfindung kann ein herkömmliches Telefonendgerät sein. Dieses verfügt gewöhnlich über eine Einrichtung zur Ausgabe akustischer Systemmeldungen, insbesondere zur Ausgabe von akustischen Rufsignalen an den Benutzer des Endgerätes. Einrichtungen zur Speicherung von Sprachsignalen die in Verbindung mit herkömmlichen Telefonendgeräten verwendet werden oder sogar in diese integriert sind, sind ebenfalls bekannt. Einfache Beispiele hierfür sind herkömmliche Anrufbeantworter. Die Erfindung sieht nun ein Bedienelement vor, dessen Betätigung im Falle eines ankommenden Anrufes diesen Anruf entgegennimmt, dabei ein Sprachsignal an den Anrufer ausgibt, welches in der Einrichtung zur Speicherung von Sprachsignalen gespeichert ist, und welches den Anrufer zum Halten der Leitung auffordert.The starting point for the implementation of the present invention can be a conventional telephone terminal. This usually has a device for outputting acoustic system messages, in particular for outputting acoustic call signals to the user of the terminal. Devices for storing voice signals which are used in connection with conventional telephone terminals or are even integrated therein are also known. Conventional answering machines are simple examples of this. The invention now provides a control element, the actuation of which receives this call in the event of an incoming call, thereby outputting a voice signal to the caller, which is stored in the device for storing voice signals, and which prompts the caller to hold the line.
Dieses Bedienelement kann ein spezielles also zusätzliches Bedienelement sein, z.B. eine zusätzliche Taste im Tastenfeld eines Telefonendgerätes, welche ausschließlich für diese Funktion vorgesehen ist. Es kann sich aber auch um ein be- reits vorhandenes Bedienelement handeln, dessen Betätigung im Falle eines ankommenden Anrufes bisher keine Funktion hatte. Des weiteren kann das erfindungsgemäße Bedienelement aber auch durch ein herkömmliches Bedienelement realisiert werden, welches im normalen Betriebszustand zwar eine andere Funktion hat, welchem aber durch eine geeignete Programmierung des Endgerätes die erfindungsgemäße Funktion, gegebenenfalls temporär, zugewiesen wird. Die verschiedenen genannten Alternativen zur Realisierung des erfindungsgemäßen Bedienelementes haben jeweils ihre, für den Fachmann offensichtlichen, Vorteile und Nachteile. Es liegt daher im Ermes- sen des Fachmannes für welche Möglichkeit zur Realisierung der vorliegenden Erfindung er sich entscheidet.This control element can be a special additional control element, for example an additional key in the keypad of a telephone terminal, which is provided exclusively for this function. However, it can also be an existing control element, the actuation of which previously had no function in the case of an incoming call. Furthermore, the control element according to the invention can also be implemented by a conventional control element, which in normal operating state has a different function, but to which the function according to the invention, possibly temporarily, is assigned by suitable programming of the terminal. The various alternatives mentioned for implementing the control element according to the invention each have their advantages and disadvantages which are obvious to the person skilled in the art. It is therefore within the discretion of the person skilled in the art which option for realizing the present invention he decides.
Durch geeignete, dem Fachmann an sich geläufige schaltungs- technische Maßnahmen ist das Bedienelement mit den anderen elektronischen Einrichtungen des Telefonendgerätes derart verbunden, daß die Betätigung des Bedienelements im Falle eines ankommenden Rufes folgendes bewirkt: a) die Verhinderung oder sofortige Beendigung der Ausgabe akustischer Systemmeldungen an den Benutzer des Endgerätes, b) die Annahme des ankommenden Rufes ohne Übertragung akustischer Signale, insbesondere Sprachsignale, zwischen Anrufer und Benutzer und c) die Ausgabe eines gespeicherten Sprachsignals an den Anrufer, mit welchem dieser zum Halten der Leitung aufgefordert wird.The control element is connected to the other electronic devices of the telephone terminal by suitable circuit-technical measures which are familiar per se to the person skilled in the art in such a way that the actuation of the control element in the event of an incoming call has the following effects: a) the prevention or immediate termination of the output of acoustic system messages the user of the terminal, b) the acceptance of the incoming call without transmission of acoustic signals, in particular voice signals, between the caller and the user and c) the output of a stored voice signal to the caller, with which the caller is asked to hold the line.
Wird also im Falle eines ankommenden Rufes das Bedienelement betätigt, noch bevor eine akustische Systemmeldung ausgegeben wurde, z.B. weil der Benutzer durch eine optische Systemmel- düng, die früher ausgegeben wurde, bereits auf den ankommenden Ruf aufmerksam gemacht worden ist, führt die Betätigung des Bedienelements zur Verhinderung der Ausgabe jeglicher akustischen Systemmeldungen, insbesondere jeglicher akustischen Rufsignale. Wurden andererseits schon akustische Sys- temmeldungen vom Endgerät ausgegeben, z.B. weil keine optischen Ausgabemöglichkeiten vorhanden sind, oder weil optische Systemmeldungen bislang vom Benutzer nicht bemerkt worden sind, wird die Ausgabe akustischer Systemmeldungen durch die Betätigung des Bedienelements beendet.If, in the case of an incoming call, the control element is actuated even before an acoustic system message has been issued, for example because the user has already been made aware of the incoming call by an optical system message that was issued earlier, the control element is actuated to prevent the output of any acoustic system messages, in particular any acoustic call signals. On the other hand, have acoustic system messages already been issued by the terminal, for example because there are no optical output options or because optical ones System messages have so far not been noticed by the user, the output of acoustic system messages is ended by actuating the control element.
Das ankommende Gespräch wird - im fernmeldetechnischen Sinne - angenommen, das heißt, es kommt - vermittlungstechnisch gesehen - eine Verbindung mit dem Anrufer zustande. Das Endgerät wird also in den Off-Hook-Zustand gebracht.The incoming call is - in the telecommunications sense - accepted, that is, it comes - from a switching point of view - a connection is established with the caller. The end device is thus brought into the off-hook state.
Im Gegensatz zu herkömmlichen Endgeräten, bei denen dieserIn contrast to conventional devices, where this
Übergang in den Off-Hook-Zustand gleichzeitig auch den Beginn einer Übertragung akustischer Signale, insbesondere von Sprachsignalen, zwischen dem Anrufer und dem Benutzer des Endgerätes bewirkt, sieht die Erfindung vor, daß eine solche Übertragung wenigstens zunächst nicht stattfindet. Gemäß der Erfindung wird statt dessen ein im Endgerät gespeichertes Sprachsignal an den Anrufer ausgegeben, mit dem dieser zum Halten der Leitung aufgefordert wird.Transition to the off-hook state at the same time as the start of a transmission of acoustic signals, in particular voice signals, between the caller and the user of the terminal, the invention provides that such a transmission does not take place at least initially. According to the invention, a voice signal stored in the terminal is instead output to the caller, with which the caller is asked to hold the line.
Die schaltungstechnische oder softwaretechnische Realisierung der hier beschriebenen erfindungsgemäßen Maßnahmen gelingt dem Fachmann ohne weiteres anhand ihm geläufiger technischer Lösungsmöglichkeiten, sobald ihm die grundsätzliche Idee der vorliegenden Erfindung anhand der hier vorliegenden Beschrei- bung erst einmal bekannt ist .The person skilled in the art can easily implement the circuitry or software technology of the measures according to the invention described here on the basis of technical solution options familiar to him as soon as he is familiar with the basic idea of the present invention based on the description here.
Bei einer besonders vorteilhaften Ausführungsform der Erfindung ist eine Ausgabe mindestens einer optischen Systemmeldung vorgesehen, die an die Stelle der verhinderten oder be- endeten akustischen Systemmeldung tritt. Die Ausgabe dieser optischen Systemmeldung wird durch die Betätigung des erfindungsgemäßen Bedienelements ausgelöst.In a particularly advantageous embodiment of the invention, an output of at least one optical system message is provided, which replaces the prevented or ended acoustic system message. The output of this optical system message is triggered by actuating the control element according to the invention.
Eine weitere besonders vorteilhafte Ausführungsform der Er- findung sieht eine Implementierung des erfindungsgemäßen Bedienelementes in einer Weise vor, die zur Folge hat, daß eine erneute Betätigung des Bedienelements die Übertragung akustischer Signale zwischen Anrufer und Benutzer einschaltet . Nach einer insgesamt zweimaligen Betätigung dieses Bedienelements ist die Verbindung mit dem Anrufer also tatsächlich voll hergestellt, nachdem die erstmalige Betätigung zunächst nur die rein vermittlungstechnische Gesprächsannahme - d.h. den Übergang des Endgeräts in den Off-Hook-Zustand - zur Folge hatte. Another particularly advantageous embodiment of the invention provides for an implementation of the control element according to the invention in a manner which has the consequence that a pressing the control element again switches on the transmission of acoustic signals between the caller and the user. After a total of two actuations of this control element, the connection with the caller is actually fully established, after the initial actuation initially only resulted in a purely mediation-related call acceptance - ie the transition of the terminal to the off-hook state.
