Abstract

The invention relates to a device for generating the missing charge signal for local, synchronous telephone charge billing within digital PBX systems which are connected to local digital exchange systems or equivalent devices, the device required for this purpose being integrated, for example, in a chip card telephone and the missing signal being generated for the start of the charge billing itself.

Description

Es sind verschiedene Systeme bekannt, die bis heute Gebührenabrechnungen zeitgleich am Teilnehmer ermög­ lichen.Various systems are known to date Billing of fees possible at the same time at the participant lichen.

All diese Systeme beruhen auf der Funktion, daß als Zählsignal für den Beginn der Gebührenabrechnung der Gebührenimpuls der Deutschen Bundespost (16 KHz) verwendet wird.All of these systems are based on the function that as Count signal for the start of the billing of the Fee impulse of the Deutsche Bundespost (16 KHz) is used.

In neuen digitalen Nebenstellenanlagen ist eine Übertragung des o. a. Signales nicht möglich, da durch die Digitalisierung nur Frequenzen bis ca. 3,5 KHz übertragen werden können.In new digital private branch exchanges there is one Transfer of the above Signals not possible because due to digitization only frequencies up to approx. 3.5 KHz can be transmitted.

Auch hierfür gibt es bereits Lösungen durch Gebüh­ rensignalumsetzungen, die das Bundespostsignal von 16 KHz in einen Bereich von ca. 3 KHz umsetzen.Solutions for this are already available through fees rensignal implementations that the federal post signal from Convert 16 KHz to a range of approx. 3 KHz.

Wird jedoch eine digitale Nebenstellenanlage an eine digitale Ortsvermittlungsstelle der Deutschen Bun­ despost angeschaltet, sendet die Bundespost keine 16 KHz Gebührensignale mehr.However, if a digital private branch exchange is connected to a digital local exchange of the Deutsche Bun despost switched on, the federal post does not send 16 KHz charge signals more.

Die im digitalen Datenpaket zwischen Ortsvermitt­ lungsstelle und Nebenstellenanlage des Teilnehmers verschlüsselt untergebrachten Gebührenimpuls-Infor­ mationen, stehen nicht mehr im zeitlichen Zusammen­ hang mit dem Gespräch, sie werden je nach Infor­ mationsfreiräumen in nicht definierten Zeitabständen verzögert bzw. teilweise erst am Gesprächsende zur Verfügung gestellt.The in the digital data packet between local exchange subscriber’s office and private branch exchange encrypts housed charge pulse information mations, are no longer in time together hang with the conversation, depending on the information  Free movement in undefined time intervals delayed or sometimes not until the end of the call Provided.

Für eine korrekte zeitgleiche dezentrale Gebühren­ abrechnung ist als Referenz für den Gesprächsbeginn das korrekte Eintreffen des Gebührensignales der Deutschen Bundespost erforderlich.For correct decentralized fees at the same time billing is a reference for starting the conversation the correct arrival of the charge signal of the German federal post required.

Mit dieser Signalisierungsart ist eine dezentrale zeitgleiche Telefongebührenabrechnung, wie sie z. B. für Chipkarten (Guthaben) Telefone erforderlich ist, nicht mehr möglich.With this type of signaling is a decentralized Simultaneous telephone billing, as z. B. for smart cards (credit) phones is required not possible anymore.

Ziel der Erfindung ist eine Einrichtung zur Erzeu­ gung des fehlenden Gebührensignales für eine dezen­ trale zeitgleiche Telefongebührenabrechnung inner­ halb von digitalen Nebenstellenanlagen, die an digi­ talen Ortsvermittlungssystemen angeschaltet sind, oder äquivalenten Einrichtungen.The aim of the invention is a device for generating the missing charge signal for a decade tral simultaneous internal telephone charge settlement half of private branch exchanges connected to digi valley local exchange systems are switched on, or equivalent facilities.

Die hierfür erforderliche Einrichtung ist in der dargestellten Lösung, z. B. in einem Chipkartentele­ fon integriert. Ziel der Erfindung ist das fehlende Signal für den Beginn der Gebührenabrechnung selbst zu generieren.The facility required for this is in the solution shown, e.g. B. in a chip card tele integrated. The aim of the invention is the lack Signal for the start of billing itself to generate.

Als Referenz wird der im Telefonhörer während des Klingelns wahrnehmbare Ton (Rufsignal) verwendet. Über den Gabelumschalter gelangen die Signale der Telefonleitung (a/b) auf eine Zweidraht/Vierdraht Weiche. Hier erfolgt die Aufteilung des Signalweges in den kommenden Hörweg und den gehenden Sprechweg.The tone (call signal) that is perceptible in the telephone handset while ringing is used as a reference. The signals of the telephone line ( a / b ) are transferred to a two-wire / four-wire switch via the hook switch. This is where the signal path is divided into the coming audio path and the outgoing speech path.

Aus dem Signalweg für den Hörer wird das nieder­ frequente Spektrum einem selektiven Filter zuge­ führt. Dieser Filter ist in seinem Resonanz- und Zeitverhalten auf die während des Anrufes auftreten­ den Töne abgestimmt. Der Ausgang des Filters wird einem Mikroprozessor zugeführt. Hier erfolgt eine weitere Selektion der empfangenen Signale, um Stö­ rungen durch Impulsspitzen/Sprache oder ähnlich auszublenden. Die technisch bereinigten Impulse werden mit einem, in der Software abgelegten, Zeit­ fenster in Vergleich gebracht. Über dieses Fenster kann bei zyklischem Signalausfall das Referenz­ signal für den Gesprächsbeginn herausgezogen werden.That becomes down from the signal path for the listener  frequency spectrum supplied to a selective filter leads. This filter is in its resonance and Time behavior that occurs during the call tuned to the tones. The output of the filter will fed to a microprocessor. Here is one further selection of the received signals to avoid interference through pulse peaks / speech or similar hide. The technically adjusted impulses with a time saved in the software window compared. About this window can be the reference in the event of cyclical signal failure signal for the start of the call.

Mit diesem Impuls beginnt der Mikroprozessor die Gebührenberechnung. Das heißt, er reduziert das Gut­ haben auf z. B. einer angeschalteten Chipkarte. Der Zeittakt für das Gespräch, d.h. die Anzahl Sekunden pro Einheit, wird über die durch den Mikroprozessor während des Wahlvorganges abgefragte Vorwahlnummer und eine im Programm abgelegte Verzonungstabelle zu­ geordnet.The microprocessor starts with this pulse Charge calculation. That means he reduces the good have on z. B. an activated chip card. The Timing for the conversation, i.e. the number of seconds per unit, is made through the microprocessor Area code requested during the dialing process and a zoning table stored in the program orderly.

Diese technische Lösung ermöglicht eine dezentrale zeitgleiche Gebührenabrechnung unabhängig von der Technologie der OVST (Ortsvermittlungsstelle) der Nebenstelle entsprechend den Tarifen der Deutschen Bundespost.This technical solution enables a decentralized simultaneous billing regardless of the Technology of the OVST (local exchange) Extension according to the tariffs of the Germans Federal post office.
