Abstract

Based on a transmission method in which a broadcast transmitter can selectively call one broadcast receiver from a multiplicity of broadcast receivers by means of a call telegram, the call telegrams are transmitted as RDS (Radio Data System) telegrams. For this purpose, the broadcast receivers have an additional call address decoder along with an RDS decoder.

Description

Die Erfindung betrifft ein verfahren zur selektiven Rufübertragung nach dem Oberbegriff des Patentanspruches 1 sowie einen Rufempfänger zur Durchführung des Verfahrens.The invention relates to a method for selective call transmission according to the preamble of claim 1 and a call receiver for performing the method.

Funkrufsysteme werden jetzt auch für den Betrieb außerhalb geschlossener Arreale installiert z.B. als Stadtfunkrufsysteme oder landesweite Funkrufsysteme. Sie verfügen über ein Sendernetz zur Aussendung der Ruftelegramme, die eine Rufadresse aufweisen. Die Ruftelegramme werden von mobilen Rufempfängern empfangen, die einen Ruf selektiv, d.h. nur dann wiedergeben, wenn das Ruftelegramm die Rufadresse des Rufempfängers enthalten hat. Zum Aufbau des Sendernetzes werden stationäre Sender eingesetzt, die auf speziell für den Funkrufdienst zugelassenen Frequenzen arbeiten; es sind aber auch schon Rundfunksender für Programmaussendung zur Aussendung von Ruftelegrammen benutzt worden.Paging systems are now also installed for operation outside of closed areas, e.g. as city paging systems or nationwide paging systems. They have a transmitter network for sending the call telegrams that have a call address. The call telegrams are received by mobile call receivers that selectively, i.e. Only play back if the call telegram has contained the call address of the call recipient. To build up the transmitter network, stationary transmitters are used, which work on frequencies specially approved for paging; however, radio transmitters have also been used for program transmission for the transmission of call telegrams.

Solange die Rufempfänger noch relativ teuer sind, werden sie nur von einem kleineren Interessentenkreis erworben und eingesetzt mit der Folge, daß es nicht gelingt, aufgrund einer Massenproduktion die Preise zu senken.As long as the call receivers are still relatively expensive, they are only acquired and used by a smaller group of interested parties, with the result that it is not possible to lower the prices due to mass production.

Es ist Ziel der Erfindung, den Funkruf einem breiteren Publikum zugänglich zu machen durch Reduzierung des technischen Aufwands.The aim of the invention is to make the paging accessible to a wider audience by reducing the technical complexity.

Diese Aufwandsreduzierung gelingt durch das Verfahren mit den Merkmalen des Patentanspruches 1 und den Rufempfänger wie im Anspruch 2 angegeben.This reduction in effort is achieved by the method with the features of claim 1 and the call receiver as specified in claim 2.

Schon bisher strahlen die Rundfunkanstalten insbesondere mit ihren Programmen für Autofahrer und insbesondere in der Ferienreisezeit an Einzelpersonen gerichtete Suchmeldungen und Durchsagen aus, wegen derer das eigentliche Programm unterbrochen werden muß. Dabei handelt es sich aber nicht um selektive Rufe; denn obwohl die Durchsagen jeweils nur eine Person betreffen, werden sie von Tausenden empfangen. Dies ist einerseits unerwünscht, andererseits geradezu notwendig, um die Wahrscheinlichkeit dafür, daß die Nachricht beim Adressaten ankommt, überhaupt auf einen akzeptablen Wert zu bringen (auch durch die Mithilfe der Mithörer).So far, the broadcasters have been broadcasting, especially with their programs for motorists and especially during the holiday season targeted at individuals and announcements, because of which the actual program must be interrupted. However, these are not selective calls; because even though the announcements only affect one person, they are received by thousands. On the one hand, this is undesirable, but on the other hand it is absolutely necessary to bring the probability that the message will reach the addressee to an acceptable level (also through the help of the listeners).

Die Erfindung geht einen anderen Weg und geht dabei davon aus, daß für Selektivrufe sendeseitig die benötigten technischen Einrichtungen vorhanden oder ihre Einführung zumindest beschlossen ist, und zwar europaweit einheitlich. Die in der EBU (European Broadcast Union) zusammengeschlossenen Rundfunkanstalten haben sich nämlich auf ein Datentelegramm geeinigt, das zugleich mit dem (Ton)Rundfunkprogramm ausgestrahlt und von entsprechend eingerichteten Rundfunkempfängern ausgewertet wird.The invention takes a different approach and assumes that the technical equipment required for selective calls on the transmission side is available or that its introduction has at least been decided, and is uniform across Europe. The broadcasters affiliated to the EBU (European Broadcast Union) have agreed on a data telegram that is also broadcast with the (sound) broadcast program and evaluated by appropriately set up broadcast receivers.

Dieses unter der Bezeichnung RDS (Radio Data System) bekannte Verfahren dient vor allem dazu, Kennungen über Sendeanstalt (z.B. Norddeutscher Rundfunk), Programmkette (z.B. drittes Programm), Programmart (z.B. Unterhaltungsmusik) usw. zu übermitteln, die für Steuerfunktionen in den mit RDS-Dekodern ausgerüsteten Rundfunkempfängern genutzt werden, z.B. Display-Ansteuerung, Lautstärkeeinstellung, Programmselektion, Abstimmung auf den jeweils am besten zu empfangenden Sender bei gleichbleibendem Programm (insbesondere bei Autoradios).This procedure, known as RDS (Radio Data System), is primarily used to transmit identifiers via the broadcaster (e.g. Norddeutscher Rundfunk), program chain (e.g. third program), program type (e.g. entertainment music) etc., which are used for control functions in those with RDS -Decoders equipped radio receivers can be used, e.g. display control, volume adjustment, program selection, Tuning to the best receivable station with the same program (especially car radios).

Wenngleich die mit RDS-Dekoder ausgerüsteten Rundfunkempfänger, insbesondere Autoradios, nicht für den selektiven Empfang der RDS-Datentelegramme ausgerüstet sind, macht sich die Erfindung die Tatsache zunutze, daß Rundfunkempfänger, insbesondere Autoradios weit verbreitet sind. Es kann damit gerechnet werden, daß auch mit RDS-Dekoder ausgerüstete Rundfunkempfänger eine weite Verbreitung finden werden. Um solche Rundfunkempfänger zugleich als Rufempfänger nutzen zu können, wird es dann nur noch nötig sein, sie mit einem zusätzlichen Rufadressen-Dekoder auszurüsten. Die dafür erforderlichen Kosten werden relativ gering sein, jedenfalls erheblich geringer als die Kosten für einen gesonderten Rufempfänger. Der reduzierte technische Aufwand wird mit dazu beitragen, daß Funkrufdienste einem breiteren Publikum zugänglich werden.Although the radio receivers, in particular car radios, equipped with RDS decoders are not equipped for the selective reception of RDS data telegrams, the invention takes advantage of the fact that radio receivers, in particular car radios, are widespread. It can be expected that radio receivers equipped with RDS decoders will also find widespread use. To be able to use such radio receivers as call receivers at the same time, it will then only be necessary to equip them with an additional call address decoder. The costs required for this will be relatively low, at least considerably lower than the costs for a separate call receiver. The reduced technical effort will help make paging services accessible to a wider audience.

Die Rufe werden von den Rundfunksendern über das RDS-Telegramm mit einer Rufadresse (z.B. entsprechend dem Kraftfahrzeug-Kennzeichen) ausgesandt. In jedem (Auto-)Rundfunkempfänger befindet sich zusätzlich zum RDS-Dekoder ein Adressendekoder, so daß die (Reise-)Rufe selektiv empfangen werden können. Durch die Reservierung eines Teils der noch freien Blöcke des RDS-Telegramms für die Individual-Adressierung und -Benachrichtigung ist eine sichere, gezielte Übermittlung von (Reise-)Rufen ohne Programmunterbrechung möglich.The calls are sent by the broadcasters via the RDS telegram with a call address (e.g. corresponding to the vehicle registration number). In addition to the RDS decoder, there is an address decoder in each (auto) radio receiver so that the (travel) calls can be received selectively. By reserving a part of the still free blocks of the RDS telegram for individual addressing and notification, a secure, targeted transmission of (travel) calls is possible without interrupting the program.

Der Rundfunkempfänger kann zweckmäßigerweise so ausgerüstet sein, daß er
a) über die zusätzliche selektive Empfangsmöglichkeit nicht permanent (unabänderlich), sondern vom Benutzer einstellbar nur während bestimmter Zeiten (z.B. Reisezeiten) verfügt,The radio receiver can be suitably equipped so that it
a) does not have the additional selective reception option permanently (unchangeable), but can only be set by the user during certain times (e.g. travel times),
