Abstract

The emergency call system operates via a digital radio network which supports receiver stations installed worldwide. Preferably the emergency call controls a control channel of the network and is transmitted on this channel. Alternatively the emergency call may control the network information channel. An emergency call transmitter combines a transmitter device in a standard wrist watch next to an electric clock mechanism. The transmitter device may be combined in a pager. Preferably the emergency signal is triggered by means of a switch in the watch cover. The emergency call signal may have a triple start to make a connection with a receiver station within 15 seconds. The contents of the signal may be encoded to relate to the emergency call and also to the person transmitting. The information may be received by the globally distributed receiver stations and analysed by them.

Description

Die vorliegende Erfindung betrifft ein global anwendbares, mobiles Notrufsystem. Es arbeitet über ein digitales Funknetz.The present invention relates to a globally applicable, mobile emergency call system. It works over a digital radio network.

Mobile Notrufsender arbeiten herkömmlich auf der Basis eines Senders kodierter elektromagnetischer Wellen und eines entsprechend Empfangsgerätes. Die Entfernung zwischen Sendegerät und Empfangsgerät ist abhängig von der Sendeleistung des Notrufsenders. Aus diesem Grunde vermögen handliche, in der Jackentasche transportierbare Sendegeräte regelmäßig nur eine geringe Distanz zu überbrücken; leistungsstarke Sendegeräte sind aufgrund des erforderlichen Energiebedarfes herkömmlicherweise schwer von Gewicht und unhandlich in der Größe. Oftmals können leistungsstarke Notrufgeräte nur im Fahrzeugbereich eingesetzt werden.Mobile emergency transmitters traditionally work coded on the basis of a transmitter electromagnetic waves and a corresponding receiver. The distance between the transmitting device and the receiving device depends on the transmission power of the emergency transmitter. For this reason, handy in your jacket pocket to transport portable transmitters regularly only a short distance; powerful transmitters are due to the required energy requirements conventionally heavy in weight and bulky in size. Often times high-performance emergency call devices can only be used in the vehicle sector.

Herkömmlich wird die Position des Senders durch Peilung vorgenommen. Dies setzt voraus, daß der Notruf einen genügend langen Zeitraum zu empfangen ist. Unter schwierigen Bedingungen etwa im Gebirge ist ein Notruf von einer Länge von mindestens 20 Minuten erforderlich. Dies wiederum beeinflußt den Bedarf an Energie und damit die Größe und das Gewicht des Gerätes. Zur Energieschonung sind zwischen den Signalen Intervalle möglich.Conventionally, the position of the transmitter is done by bearing. This assumes that the emergency call can be received for a sufficiently long period of time. In difficult conditions, such as in the mountains, an emergency call is long of at least 20 minutes required. This in turn affects demand Energy and therefore the size and weight of the device. For energy conservation intervals are possible between the signals.

Herkömmlicherweise erfüllt der Sender keinerlei Empfangsfunktionen. Eine Anzeige, ob der Sender zur jeweiligen Zeit einen Empfänger erreichen kann, findet nicht statt.The transmitter traditionally does not perform any reception functions. An ad, Whether the sender can reach a receiver at any given time is not found instead of.

Bei herkömmlichen Notrufsystemen findet in der Empfangszentrale ein 24-Stunden-Bereitschaftsdienst statt, der die betreffenden Notrufempfänger alarmiert. Erreicht der Bereitschaftsdienst den zu alarmierenden Adressaten, vermerkt er dies und stellt weitere Alarmierungsversuche ein.In conventional emergency call systems, there is a 24-hour standby service in the reception center instead, which alarms the concerned emergency call recipient. If the emergency service reaches the addressee to be alarmed, he notes this and stops further alarm attempts.

Herkömmlicherweise finden Energieträger, insbesondere Batterien und Akkumulatoren, Anwendung. Die Akkumulatoren müssen in regelmäßigen Abständen entleert und wieder aufgeladen werden, damit sich ihre Speicherkapazität nicht verringert. Dies ist ein zusätzlicher Wartungsaufwand, der gerade für ein System typisch ist, welches nur im Notfall gebraucht wird. Batterien müssen regelmäßig ausgetauscht werden, auch wenn sie nicht benutzt wurden.Traditionally, energy sources, in particular batteries and accumulators, Application. The accumulators must be emptied at regular intervals and recharged so that their storage capacity does not decrease. This is an additional amount of maintenance that is typical of a system which is only used in an emergency. Batteries need to be replaced regularly even if they have not been used.

Die Auslösung des Notrufes kann herkömmlicherweise durch eigene oder fremde Hand gestoppt werden. Ferner kann üblicherweise das Notrufgerät von seinem Träger getrennt werden.The triggering of the emergency call can traditionally be done by your own or someone else's Be stopped by hand. Furthermore, the emergency call device can usually Carrier be separated.

Zum Zwecke des permanenten, situationsunabhängigen Schutzes besteht die Notwendigkeit, einen Notrufsender von seinen Außmaßen her klein und von leichtem Gewicht zu gestalten. Ferner sollte der Notrufsender weltweit einsetzbar sein. Des weiteren sind Wartungsleistungen auf ein Minimum zu reduzieren. Die Störanfälligkeit, etwa durch eindringendes Wasser wie auch durch Stöße muß ebenfalls auf ein Minimum reduziert werden. For the purpose of permanent, situation-independent protection Need for an emergency transmitter to be small in size and light in weight Shape weight. Furthermore, the emergency transmitter should be usable worldwide. Maintenance services must also be reduced to a minimum. The susceptibility to failure, for example by penetrating water as well as by knocks be reduced to a minimum.

Die Ortung muß schnell und zuverlässig gewährleistet sein. Es muß für den Absender des Notrufes ständig die Sicherheit bestehen, daß sein Notruf den Empfänger und somit die Adressaten erreicht. Der Sender muß optisch unauffällig sein, so daß ein etwaiger Attentäter nicht den Argwohn faßt, es könnte sich dabei um einen Notrufsender handeln. Es soll zumindest eine Varlante entwickelt werden, bei der die Trennung des Notrufsenders nach Absendung des Notrufsignals nicht mehr von dein Absender getrennt werden kann.The location must be ensured quickly and reliably. It must be for the Sender of the emergency call is constantly assured that his or her emergency call Recipient and thus the addressees reached. The transmitter must be optically inconspicuous so that a possible assassin does not suspect that this could happen act as an emergency transmitter. At least one varlante should be developed be in which the disconnection of the emergency transmitter after sending the emergency signal can no longer be separated from your sender.

Vorgenannte Aufgaben werden erfindungsgemäß durch folgendes Gerät bzw. dessen Variante gelöst:According to the invention, the aforementioned tasks are performed by the following device or its variant solved:

Es handelt sich um ein weltweit einsetzbares, mobiles Notrufsystem, welches im Gehäuse einer Armbanduhr Platz findet und am Handgelenk bzw. im Format eines gewöhnlichen Pagers in der Jackentaschse oder am Gürtel transportiert werden kann.It is a mobile emergency call system that can be used worldwide A watch case fits on the wrist or in the format of a watch ordinary pagers can be carried in the jacket pocket or on the belt can.

Die Übertragung des Notrufs soll über digitale Funknetze erfolgen, und zwar über deren Steuerkanäle, nicht aber über deren Nutzkanäle. Zu den digitalen Netzen zählen derzeit das GSM-Funknetz (D-Netz), das E-Plus-Netz sowie das zukünftige F-Netz. Das GSM-Netz ist ein weltweites Funknetz, weiches in globaler Verteilung auf Empfänger-Parzellen basiert. Diese Parzellen sind so eingerichtet, daß der Sender jeweils den nächstgelegenen Empfänger anzusteuern hat Von dem Empfänger des Signals aus wird auf der Basis herkömmlicher Telefonleitungen weitergeleitet.The emergency call is to be transmitted via digital radio networks, namely via their control channels, but not via their useful channels. To the digital networks currently include the GSM radio network (D network), the E-Plus network and the future one F network. The GSM network is a worldwide radio network, soft in a global distribution based on recipient parcels. These plots are set up so that the Sender has to control the nearest receiver The receiver of the signal is based on conventional telephone lines forwarded.

Daraus resultiert, daß die Sendeleistung des Senders nur eine Reichweite von wenigen Kilometern überbrücken muß, um einen weltweiten Schutz zu bieten.The result of this is that the transmit power of the transmitter only has a range of bridge a few kilometers to provide worldwide protection.

Der Sender soll in einem Uhrgehäuse mit Ausdehnungen von etwa einer Höhe von 10 mm und einem Durchmesser von höchstens 40 mm untergebracht werden, wobei der vorgenannte Raum nicht völlig ausgenutzt wird durch den Sender. Dadurch ist gewährleistet, daß ein elektronisch bzw. quarzgesteuertes Uhrwerk Platz findet. Dies ist erforderlich, um zu gewährleisten, daß das Gerät nach außen hin allein als Uhr zu erkennen ist; ferner gewährleistet dieses, daß die Energieträger (Batterien oder Akkumulatoren) ständig gefordert werden.The transmitter is said to be in a watch case with dimensions of approximately a height of 10 mm and a diameter of at most 40 mm, the aforementioned space is not fully used by the transmitter. This ensures that an electronic or quartz-controlled clockwork Finds space. This is necessary to ensure that the device is outside can only be recognized as a clock; this also ensures that the energy sources (Batteries or accumulators) are constantly required.

Die als Variante mögliche Unterbringung der Sendetechnik im Armband anstatt im Uhrgehäuse erlaubt auch ein Gehäuse von einem Durchmesser von nur etwa 1 cm bzw. die Unterbringung von aufwendiger Uhrentechnik im Uhrgehäuse.The possible accommodation of the transmission technology in the bracelet instead of in the Watch case also allows a case with a diameter of only about 1 cm or the accommodation of complex watch technology in the watch case.

Der Notrufsender kann von der absendenden Person unter Zuhilfenahme der Hand, an deren Gelenk sich das Gerät nicht befindet, an beliebigem Ort und in beliebiger Position ausgelöst werden. The emergency transmitter can be sent by the sending person with the help of the Hand, on the joint of which the device is not located, in any place and in in any position.

Der Notruf alarmiert eine Notrufzentrale. Das Notrufsignal enthält eine einmalige Kennung, die Auskunft über die Person erteilt, die den Notruf abgesandt hat. In Verbindung mit der Kennung werden Personen festgelegt, die bei einem Notruf zu benachrichtigen sind. Dies kann auch ausschließlich die Polizei sein. Die Benachrichtigung wird von der Notrufzentrale gesteuert.The emergency call alerts an emergency center. The emergency signal contains a one-off Identifier that provides information about the person who sent the emergency call. In Connection with the identifier are defined for people who respond to an emergency call are notify. This can also be the police only. The notification is controlled by the emergency center.

Die Ortung des Absenders erfolgt in zwei Schritten. Aufgrund der Anwendung eines digitalen Funknetzes steht bereits beim Empfang des Notrufes fest, in welcher Parzelle des Funknetzes sich der Absender befindet. Durch einen im Anschluß an das eigentliche Notrufsignal ausgesandten Peilruf erfolgt die Feinortung im normalen Peilverfahren.The sender is located in two steps. Because of the application of a digital radio network is already fixed when the emergency call is received which parcel of the radio network the sender is located. Through an im Follow-up to the actual call signal sent by the bearing call is carried out in the normal DF procedure.

Die Ortung des Peilsignals soll über einen mobilen Scanner erfolgen. Dieser hat die äußere Form eines Pagers oder wird sogar in einem Pager untergebracht. Er gibt beim Empfang des Peilsignals ein akustisches Alarmzeichen von sich, und zwar in Intervallen, die kürzer werden, je stärker das Peilsignal empfangen wird. Eine Entfernungsschätzung kann durch einen Prozessor vorgenommen und durch ein Display angezeigt werden.The bearing signal should be located using a mobile scanner. This one has the external form of a pager or is even accommodated in a pager. He gives an acoustic alarm signal from itself when the direction-finding signal is received, namely in Intervals that become shorter the stronger the DF signal is received. A Distance estimation can be done by a processor and by a Display.

Das Sendegerät, sei es in Form eines Uhrgehäuses oder im Format eines Pagers, muß wasserdicht und stoßfest sein. Es darf durch einfache Zerstörungsmaßnahmen nicht zu beeinträchtigen sein.The sending device, be it in the form of a watch case or in the form of a pager, must be waterproof and shockproof. It can be done by simple destruction measures not to be affected.

Das digitale Funknetz muß über eine Einrichtung verfügen, durch die ein Notruf erkannt werden kann und die solche Daten festhält, aus denen hervorgeht, in welcher Funkzelle der Notruf abgesandt wurde.The digital radio network must have a facility through which an emergency call can be made can be recognized and which records such data from which emerges in which radio cell the emergency call was sent from.

Die Form des Senders, die als Armbanduhr am Handgelenk getragen wird, erhält eine zusätzliche Energieversorgung außerhalb des eigentlichen Uhrgehäuses durch weitere Versorgungszellen in den Gliedern des Armbandes.The shape of the transmitter, which is worn as a wristwatch, is preserved an additional power supply outside of the actual watch case additional supply cells in the links of the bracelet.

Ein weiteres Ausstattungsmerkmal der Uhr werden Solarzellen sein, die einen Teil der Energieversorgung mit übernehmen. Dies dient der gelegentlichen Auffüllung der Batterie zu Zeiten der Einstrahlung von direktem oder diffusem Licht. Die Batterie entlädt sich stetig durch den Betrieb der Uhr. Der Ladezustand der Akkumulatoren oder Batterien verändert sich mithin, bleibt im Durchschnitt jedoch konstant und ist stets einsatzbereit. Eine Kapazitätsanzeige gibt Auskunft über den Ladezustand der Akkus.Another feature of the watch will be solar cells, some of which with the energy supply. This is for occasional replenishment the battery at times of direct or diffuse light. The The battery discharges itself continuously through the operation of the watch. The state of charge of the Accumulators or batteries change accordingly, but remain on average constant and is always ready for use. A capacity display provides information about the state of charge of the batteries.

Der Alarm wird ausgelöst durch einen Auslöseschalter. Bei dem Sender im Format eines gewöhnlichen Pagers ist der Auslöser ein Schalter, dessen Betätigung nur in ganz eindeutiger Art und Weise erfolgen kann und der gegen ein zufälliges Betätigen geschützt ist. Dies ist dadurch gewährleistet, daß der Schalter eine Druckbetätigung auf einen Knopf erfordert, der hinter der Oberfläche des Gerätes zurückspringt, der zur Betätigung einen vergleichsweisen hohen Widerstand bietet und der ferner durch eine Kunststoffkappe geschützt ist, die vor der Betätigung auf einfache Art und Weise entfernt werden muß, die jedoch stark genug ist, einen Stoß abzufangen, der eine zur Betätigung des Schalters genügende Tiefe aufweist. The alarm is triggered by a trigger switch. At the station in format The trigger of a common pager is a switch, the actuation of which is only in can be done in a very clear manner and against accidental actuation is protected. This is ensured by the switch pressing a button requires a button that jumps back behind the surface of the device, which offers a comparatively high resistance to actuation and which is also protected by a plastic cap that is on before actuation must be removed in a simple manner, but which is strong enough for one Intercept shock that has a sufficient depth to operate the switch.

Der Sender im Uhrwerk wird betätigt durch einen Auslöser, der im Verschluß des Armbandes lokalisiert ist. Die unmißverständliche Betätigung des Auslösers im Armbandverschluß löst den Notruf aus und verschließt den Armbandverschluß in einer Art und Weise, daß sie nur mit großer Gewalt und unter Zerbrechen der Armbandglieder wieder zu lösen ist. Der Auslöser kann allerdings auch in einem Zustand ausgelöst werden, in dem die Uhr nicht am Arm getragen wird und also der Verschluß des Armbandes geöffnet ist. In diesem Falle reagiert nur der Notruf, der Armbandverschluß bleibt unbeteiligt. Die elektrische Verbindung zur Elektronik in der Uhr wird gestaltet durch die Integration eines Leiters bzw. einer Leiterbahn in die einzelnen Glieder des Armbandes. Durch eine isolierte und wasserdichte Verbindung gelangt der Leiter in das Uhrgehäuse.The transmitter in the clockwork is actuated by a trigger that is in the shutter of the Bracelet is located. The unmistakable actuation of the trigger in Wristband clasp triggers the emergency call and closes the wristband clasp in in a way that they can only be done with great force and breaking the links of the bracelet is to be solved again. However, the trigger can also be in one State triggered when the watch is not worn on the arm and so the bracelet clasp is open. In this case only the emergency call responds, the bracelet clasp remains uninvolved. The electrical connection to the electronics in the clock is designed by integrating a conductor or a conductor track into the individual links of the bracelet. With an insulated and waterproof The conductor enters the watch case.

Mit der Auslösung des Alarms wird für etwa 15 Sekunden ein Notrufsignal an den nächsten Funkempfänger in der entsprechenden Funkparzelle gesendet; in dieser Zeit wird dreimal ein Verbindungsaufbau zum Empfänger gestartet. Nach Ablauf dieser Zeit geht der Sender über, ein Peilsignal in 10-Sekunden-Intervallen auszusenden. Letzteres Signal wird mit deutlich verringerter Intensität ausgesandt als das zuvor abgesandte Notrufsignal, eine Sendeleistung von 10 % der Leistung des Notrufsignals wird jedoch stets überschritten.When the alarm is triggered, an emergency call signal is sent to the next radio receiver sent in the corresponding radio parcel; in this A connection to the receiver is started three times. After expiration At this time, the transmitter goes on to send out a directional signal at 10-second intervals. The latter signal is transmitted with a significantly reduced intensity as the previously sent emergency signal, a transmission power of 10% of the power of the However, the emergency signal is always exceeded.

Als Variante ist denkbar, das Peilsignal in Intervallen von 20 Sekunden auszustrahlen, um Sendeenergie zu sparen. Dies ist zu empfehlen dort, wo nach etwa einer oder fünf Minuten ein zweites, gleichlautendes Notrufsignal ausgesandt werden soll mit dem Ziel sicher zu gehen, daß mindestens eins empfangen wird.As a variant, it is conceivable to transmit the direction finding signal at intervals of 20 seconds, to save transmission energy. This is recommended where after about one or a second, identical emergency signal is sent out for five minutes The aim is to ensure that at least one is received.

Die Aussendung des Notrufsignals und später des Peilsignals kann nur durch Zerstörung des Sendegerätes gestoppt werden. Das Notrufsignal soll ein nach dem GSM-Standard vorgegebenes Format erhalten und auf einer GSM-Frequenz gesandt werden, die das GSM-Netz für den Signalisierungskanal bereitstellt. Es enthält neben den GSM-typischen-Daten folgende Informationen: das erste Signal ist eine Information, die der Netzzentrale, in der das Notrufsignal als erstes aufläuft, mitteilt, daß es sich überhaupt um einen Notruf handelt. Das zweite Signal enthält die einmalige Kennung, die Auskunft über die absendende Person gibt. Sobald beide Informationen in der Netzzentrale identifiziert worden sind, wird ein automatischer Ablauf aktiviert, durch den die Adressaten benachrichtigt werden. Der automatische Ablauf wird betrieben durch einen automatischen Telefonanrufer, der den Adressaten eine kurze, digital gespeicherte Nachricht übermittelt. Unter den Nachrichten ist auch die Netzparzelle automatisch zu übermitteln.The transmission of the emergency call signal and later the DF signal can only be done by Destruction of the transmitter can be stopped. The emergency signal is supposed to be after receive the format specified in the GSM standard and on a GSM frequency be sent, which the GSM network provides for the signaling channel. It contains the following information in addition to the typical GSM data: the first signal is information that the network center in which the emergency call signal first appears announces that it is an emergency call at all. The second signal contains the unique identifier that provides information about the sending person. As soon as both pieces of information have been identified in the network center, a automatic process activated by which the addressees are notified. The automatic process is operated by an automatic telephone caller, who transmits a short, digitally stored message to the addressees. The network parcel must also be transmitted automatically under the messages.

Das Peilsignal muß eine Frequenz knapp über oder unter der üblichen GSM-Frequenz haben, da die Bandbreite des Senders eingeschränkt ist und an sich nur eine Frequenz zur Verfügung steht. Es erhält eine einmalige Modulation, um eine Fehlfunktion oder eine Verwirrung über den Absender zuverlässig zu vermeiden. The bearing signal must have a frequency just above or below the usual GSM frequency have because the bandwidth of the transmitter is limited and only a frequency is available. It receives a one-time modulation to one To reliably avoid malfunction or confusion about the sender.

Das Peilsignal wird solange ausgestrahlt, bis die Energiereserven des Senders aufgebraucht sind. Der Sender verfügt über eine Bereitschaftsanzeige, die dem Anwender Informationen darüber gibt, ob eine Funkverbindung zu einer Funkzelle besteht oder nicht. Die Empfangsempfindlichkeit der Bereitschaftseinheit im Sender ist so abgestimmt, daß sie in Abhängigkeit der Sendeleistung des Senders anzeigt. Die Bereitschaftseinheit zeigt präzise an, daß der Sender eine zu große Distanz zur Funkzelle überbrücken müßte.The DF signal is broadcast until the transmitter's energy reserves are used up. The transmitter has a ready indicator that the User gives information about whether a radio connection to a radio cell exists or not. The reception sensitivity of the standby unit in Transmitter is tuned so that it depends on the transmission power of the transmitter displays. The standby unit indicates precisely that the transmitter is too large Should have bridged the distance to the radio cell.

Da der Notruf über einen Steuerkanal ausgestrahlt wird, die auch dann zahlreich zur Verfügung stehen müssen, wenn die Nutzkanäle belegt sind, ist mit einer Belegung aller an sich verfügbaren Kanäle nicht zu rechnen. Die Variante mit dem zweiten Notruf dient lediglich dem Ausschluß auch des letzten Restrisikos.Because the emergency call is broadcast over a control channel, which is then numerous must be available when the user channels are occupied is with an assignment not count all channels available per se. The variant with the The second emergency call only serves to exclude the last residual risk.

Die Netzzentrale ist mit den einzelnen Funkzellen eines GSM-Netzes verbunden. An die Netzzentrale ist eine Systemeinheit gekoppelt, die den Signalisierungskanal ständig auf eingehende Notrufsignale überwacht.The network center is connected to the individual radio cells of a GSM network. A system unit, which is the signaling channel, is coupled to the network control center constantly monitored for incoming emergency signals.

Das erkannte Notrufsignal wird zuerst auf die einzigartige Kennung untersucht. Diese erhält das Signal durch die jeweilige Lizenzkarte, die einmalig mit den Kodenummern der Adressaten etc. versehen ist, die alarmiert werden. Wird ein entsprechender Eintrag gefunden, wird die Alarmierung ausgeführt.The recognized emergency signal is first examined for the unique identifier. This receives the signal from the respective license card, which is unique with the code numbers the addressees etc. who are alerted. Will be a corresponding one If an entry is found, the alarm is triggered.

Bei der Alarmierung werden die Personen, die in einem entsprechenden Eintrag gefunden werden, automatisch angerufen. Wird ein solcher Anruf entgegengenommen, so hört die betreffende Person eine Sprachansage mit der Aufforderung, den Notruf zu quittieren, also die Notrufzentrale zurückzurufen und zu bestätigen, den Notruf erhalten zu haben. Ferner übermittelt die Sprachansage die Notrufkennung sowie die Funkparzelle, in welcher der Notruf empfangen wurde, um eine grobe Lokalisierung des Notrufes unverzüglich zu übermitteln.When alerting, the people who are in a corresponding entry are found, called automatically. If such a call is answered, the person concerned hears a voice announcement with the request that the To acknowledge the emergency call, i.e. to call and confirm the emergency call center To have received an emergency call. The voice announcement also transmits the emergency call identifier and the radio parcel in which the emergency call was received by a rough one Transmit localization of the emergency call immediately.

Wenn die Quittierung der zu benachrichtigenden Person(en) erfolgt ist, werden die entsprechenden Benachrichtigungsanrufe gestoppt. Die Benachrichtigunganrufe erfolgen parallel an alle Personen, die mit einem Notruf in der Datenbank verknüpft sind.When the person (s) to be notified has been acknowledged, the corresponding notification calls stopped. The notification calls are made in parallel to all people linked to an emergency call in the database are.

Der Notruf kann durch ein Pagersystem angeboten werden. In Deutschland werden derzeit u.a. die Pagersysteme Scall, City-Ruf, Quix, Skyper angeboten. In der Datenbank der Netzzentrale können zur Benachrichtigung sowohl Telefonnummern als auch Pagernummern aufgeführt werden. Bei der Pageralarmierung wird durch die Alarmierungseinheit der Netzzentrale ein Benachrichtigungsauftrag an einen Pagerdienstanbieter erteilt, über welchen dann die Nachricht an den entsprechenden Empfänger verschickt wird. Hierbei soll ein Pagersystem angewendet werden, welches in der Lage ist, alphanumerische Informationen zu bearbeiten. Die entsprechenden Informationen werden auf dem Display des Pagers angezeigt. Der Pager alarmiert den Adressaten daneben akustisch über den Umstand des Notrufes. Eine Quittierung des Notrufes kann auch dann nur über Telefon erfolgen, wenn die Notrufnachricht über einen Pager erfolgte. The emergency call can be offered through a pager system. In Germany are currently offered the pager systems Scall, City-Ruf, Quix, Skyper. In The database of the network center can be used to notify both telephone numbers as well as pager numbers are listed. In the case of page alarms by the alarm unit of the network center to a notification order issued a pager service provider, through which the message is then sent to the corresponding Recipient is sent. A pager system is to be used here which is able to process alphanumeric information. The relevant information is shown on the pager display. The pager also acoustically alerts the addressee of the fact of the Emergency call. The emergency call can only be acknowledged by telephone if the emergency message was made via a pager.

Das Notrufsystem soll über die Steuerkanäle des GSM-Netzes arbeiten. Eine spätere Weiterentwickelung, die das Einbeziehen der Nutzkanäle mit sich führt, ist möglich.The emergency call system is supposed to work via the control channels of the GSM network. A later one Further development, which involves the inclusion of the user channels, is possible.

Die Quittierung des Notrufs erfolgt im DTMF-Format und wird über das Telefon eingegeben. Es handelt sich dabei um einen ebenso einmaligen Code, wie es der der Notrufkennung ist, der nur denjenigen Personen bekanntgemacht wird, die für einen Benachrichtigungsanruf bestimmt sind. Die Person, die den Notruf abgesandt hat, darf den Code nicht kennen. Dies allein gewährleistet, daß der Notruf nicht unter Zwang quittiert werden kann, wodurch die Benachrichtigungsanrufe gestoppt würden.The emergency call is acknowledged in DTMF format and is sent over the phone entered. It is as unique a code as the is the emergency identifier, which is only made known to those who are responsible for a notification call is intended. The person who sent the emergency call has to know the code. This alone ensures that the emergency call cannot be acknowledged under duress, causing the notification calls would be stopped.

Nach der Notrufsignalübertragung auf dem DCCH-Steuerkanal im GSM-Netz wird die zugehörige Funkzelle durch den "Stand-Alone Dedicated Control Channel (SDCCH)" ermittelt. In diesem Moment sendet der Notrufsender bereits das Peilsignal. Dieses kann mit dein Peilgerät genauer lokalisiert werden.After the emergency signal transmission on the DCCH control channel in the GSM network the associated radio cell through the "Stand-Alone Dedicated Control Channel (SDCCH) "is determined. At this moment the emergency transmitter is already sending the direction signal. This can be located more precisely with your direction finder.
