Die Erfindung bezieht sich auf ein Verfahren zur Guthabenerfas¬ sung für einen Vorauszahlungs-Service im Fernsprechwesen. Ein solcher Telefonservice mit Vorausbezahlung hat insbesondere in solchen Gegenden Bedeutung, in denen Zahlungen über ein Konto, d.h. der bargeldlose Zahlungsverkehr nicht sehr verbreitet sind.The invention relates to a method for recording credit for a prepayment service in telephony. Such prepaid telephone service is particularly important in areas where payments are made through an account, i.e. cashless payments are not very common.
Der Erfindung liegt die Aufgabe zugrunde, ein Verfahren anzuge¬ ben, mit dem auf einfache und sichere Weise die Guthabenerfas- sung bei Vorausbezahlung durchgeführt werden kann.The invention is based on the object of specifying a method with which the credit entry can be carried out in a simple and secure manner with prepayment.
Diese Aufgabe wird gemäß der Erfindung mit einem Verfahren der eingangs beschriebenen Art gelöst, das folgende Schritte auf¬ weist: Erstellung eines Guthabens in der Weise, daß die Telefonnummer des Teilnehmers und der Betrag des gewünschten Guthabens in ei¬ ne einen Verschlüsselungs-Algorithmus beinhaltende Einrichtung eingegeben werden und die Einrichtung eine verschlüsselte Zahl ausgibt, die die Telefonnummer des Teilnehmers, den Betrag des Guthabens sowie weitere gewünschte Informationen enthält;This object is achieved according to the invention with a method of the type described in the introduction, which has the following steps: Creation of a credit in such a way that the telephone number of the subscriber and the amount of the desired credit in a device containing an encryption algorithm entered and the facility outputs an encrypted number containing the subscriber's telephone number, the amount of the credit and other desired information;
Erfassung des Guthabens in einer entsprechenden Funktionsein¬ heit des Fernsprechnetzes/Funknetzes durch Anwählen eines spe¬ ziellen Zugriffscodes und Eingabe der verschlüsselten Zahl in den Telefonapparat des Teilnehmers und daraufhin erfolgende Entschlüsselung der verschlüsselten Zahl und Registrierung des Guthabens des Teilnehmers;Detection of the credit in a corresponding functional unit of the telephone network / radio network by dialing a special access code and entering the encrypted number in the subscriber's telephone set and then decrypting the encrypted number and registering the subscriber's credit;
Abbuchung des entsprechenden Betrages vom Guthaben für jewei¬ lige Telefongespräche. Mit diesem Service kann ein Teilnehmer einem Serviceanbieter, also z.B. einem Netzbetreiber einen bestimmten Betrag im voraus zahlen. Mit dem seinem Konto gutgeschriebenen Guthaben telefo¬ niert der Teilnehmer, bis es aufgebraucht ist. Dabei wird wäh- rend jedes Telefongesprächs eine entsprechende Gebühr vom Gut¬ haben des Teilnehmers abgebucht. Ist das Guthaben aufgebraucht, sind Telefongespräche solange nicht möglich, bis der Teilnehmer erneut gezahlt hat.Debit the corresponding amount from the credit for phone calls. With this service, a subscriber can pay a certain amount in advance to a service provider, for example a network operator. The subscriber telephones with the credit credited to his account until it is used up. A corresponding fee is debited from the subscriber's credit during each telephone call. If the credit has been used up, telephone calls are not possible until the participant has paid again.
Vorteilhafte Ausgestaltungen und Weiterbildungen des Erfin¬ dungsgegenstandes sind in den Unteransprüchen angegeben.Advantageous refinements and developments of the subject matter of the invention are specified in the subclaims.
Nachstehend wird die Erfindung anhand eines in der Zeichnung dargestellten Ausführungsbeispiels näher erläutert. Dabei sind in den Fig. 1 bis 3 jeweils in einem Blockschaltbild die Ver¬ fahrensschritte beim Erwerb und der Erfassung des Guthabens an¬ gegeben.The invention is explained in more detail below on the basis of an exemplary embodiment shown in the drawing. 1 to 3, the process steps for acquiring and recording the credit are given in a block diagram.
Der Erwerb des Guthabens erfolgt in der in Fig. 1 dargestellten Weise. Dabei enthält das Kästchen 1 Daten des Teilnehmers, wie dessen Telefonnummer, den gewünschten Betrag des Guthabens und andere Informationen. Kästchen 2 beinhaltet einen Verschlüsse¬ lungs-Algorithmus, Kästchen 3 eine verschlüsselte Zahl, die die Teilnehmernummer, das Guthaben und andere Informationen in ver- schlüsselter Form enthält.The credit is acquired in the manner shown in FIG. 1. Box 1 contains data of the participant, such as their telephone number, the desired amount of credit and other information. Box 2 contains an encryption algorithm, box 3 an encrypted number which contains the subscriber number, the credit and other information in encrypted form.
Der Erwerb des Guthabens erfolgt in der Weise, daß der Teilneh¬ mer seine Telefonnummer (z.B. auf einer Karte codiert) sowie den Geldbetrag, für den er ein Guthaben wünscht, in einer ent- sprechenden Institution, beispielsweise einem vom Netzbetreiber hierfür autorisierten Laden bzw. dem betreffenden Guthabenver¬ käufer übergibt. Diese Daten werden in eine hierfür vorgesehene Einrichtung (credit vending machine) eingegeben, woraufhin eine Zahl ausgedruckt wird. Diese Zahl ist eine Verschlüsselung der Teilnehmernummer, des Betrages des Guthabens und anderer Infor- mationen, die vom Netzbetreiber gewünscht werden, beispielswei¬ se der Verkaufsstellencode oder das Datum des Erwerbs des Gut¬ habens.The credit is acquired in such a way that the subscriber has his telephone number (for example encoded on a card) and the amount of money for which he wishes to have credit in a corresponding institution, for example in a shop or store authorized by the network operator. hands over to the relevant credit seller. This data is entered into a facility provided for this purpose (credit vending machine), whereupon a number is printed out. This number is an encryption of the participant number, the amount of the credit and other information Mations desired by the network operator, for example the point of sale code or the date of purchase of the credit.
Die Erfassung bzw. Registrierung des Guthabens wird anhand von Fig. 2 erläutert. Dabei ist in dem Kästchen 4 die verschlüssel¬ te Zahl enthalten, in Kästchen 5 der Entschlüsselungs-Algorith¬ mus und in Kästchen 6 befinden sich die entschlüsselten Daten und Informationen. Mit 7 ist ein Entscheider bezeichnet, der über die Gültigkeit aller Daten befindet, Kästchen 8 gibt dieThe detection or registration of the credit is explained with reference to FIG. 2. Box 4 contains the encrypted number, box 5 contains the decryption algorithm and box 6 contains the decrypted data and information. With 7 a decision maker is designated who is about the validity of all data, box 8 gives the
Zurückweisung bei negativem Ergebnis des Entscheiders an, Käst¬ chen 9 enthält einen Speicher für die Guthabenerfassung. Die Erfassung des Guthabens in einer entsprechenden Funktionsein¬ heit des Fernsprechnetzes erfolgt über das eigene Telefon des Teilnehmers. Hierzu wird zunächst ein spezieller Zugriffscode gewählt und danach die verschlüsselte Zahl eingegeben. Die ver¬ schlüsselte Zahl wird decodiert und, nach Überprüfung der Gül¬ tigkeit aller Daten gemäß dem in Fig. 2 gezeigten Ablauf wird der Betrag des Guthabens dem Teilnehmerkonto gutgeschrieben bzw. einem noch vorhandenen Guthaben aufaddiert. Die Verschlüs¬ selungszahl und der Entschlüsselungs-Algorithmus sind von sol¬ cher Art, daß jede verschlüsselte Zahl nur einmal benutzt wer¬ den kann. Die verschlüsselte Zahl arbeitet außerdem nur für den Teilnehmer, für welchen sie verschlüsselt wurde. Bei Eingabe der Zahl in ein anderes Telefon funktioniert es nicht.Rejection in the event of a negative result by the decision maker, box 9 contains a memory for the credit entry. The credit is recorded in a corresponding functional unit of the telephone network via the subscriber's own telephone. To do this, a special access code is first selected and then the encrypted number is entered. The encrypted number is decoded and, after checking the validity of all the data in accordance with the sequence shown in FIG. 2, the amount of the credit is credited to the subscriber account or added to a credit still available. The encryption number and the decryption algorithm are of such a type that each encrypted number can only be used once. The encrypted number also only works for the subscriber for whom it was encrypted. If the number is entered on another phone, it will not work.
Der Teilnehmer kann nun sein Telefon benutzen und Telefonge¬ spräche führen, solange er ein Guthaben besitzt. Mit jedem Te¬ lefonat vermindert sich der Betrag des Guthabens entsprechend den Gebühren des Telefonats. Sobald das Guthaben aufgebraucht ist, wird das Telefon gesperrt.The subscriber can now use his phone and make phone calls as long as he has a credit. With each telephone call, the amount of the credit decreases in accordance with the call charges. As soon as the credit is used up, the phone is blocked.
Im Fernsprechwesen erfolgt die Guthabenerfassung bzw. Regi¬ strierung in einer Funktionseinheit, einer sogenannten Gutha- benregistrationseinrichtung. Die Guthabenerfassung kann gemäß dem in Fig. 3 angegebenen Bei¬ spiel erfolgen. Dabei ist mit 10 ein Telefon für den Vorauszah¬ lungs-Service bezeichnet, in das die verschlüsselte Zahl einge- geben wird. Das Telefon 10 ist mit einer Guthabenerfassungsein¬ richtung 11 verbunden, in der zur Registrierung des Guthabens die in Fig. 2 angegebenen Schritte ausgeführt werden. Diese Einrichtung speichert nach Ablauf der entsprechenden Verfah¬ rensschritte das neue Guthaben. Die Einrichtung zur Guthabenre- gistrierung kann dabei Teil des Telefonservice mit Vorauszah¬ lung, Teil der Telefonvermittlungseinrichtung, eine externe Einrichtung, die mit der Telefonvermittlungseinrichtung verbun¬ den ist, oder Teil des intelligenten Netzwerkes sein.In telephony, the credit is recorded or registered in a functional unit, a so-called credit registration facility. The credit can be recorded in accordance with the example shown in FIG. 3. 10 denotes a telephone for the prepayment service, into which the encrypted number is entered. The telephone 10 is connected to a credit detection device 11, in which the steps indicated in FIG. 2 are carried out to register the credit. This device stores the new credit after the corresponding procedural steps have expired. The device for credit registration can be part of the telephone service with prepayment, part of the telephone switching device, an external device that is connected to the telephone switching device, or part of the intelligent network.
Das erfindungsgemäße Verfahren kann in vielfältiger Weise be¬ nutzt werden, beispielsweise für Teilnehmer des öffentlichen Fernsprechnetzes oder in Mobilfunknetzen. The method according to the invention can be used in a variety of ways, for example for subscribers to the public telephone network or in mobile radio networks.
