"Nachrichtenübermittlungssystem""Messaging system"
Die Erfindung betrifft ein System zur Übermittlung von Nachrichtenblocken zwischen mehreren, auf dem gleichen Nachricht eBkanal arbeitenden Stationen,unter Anwendung einer asynchronen zeitlichen Staffelung der Übertragungszeitpunkte für die einzelnen Stationen«, The invention relates to a system for transmitting Message blocking between several stations working on the same message eBkanal, using an asynchronous time grading of the transmission times for the individual stations «,

Anwahl, ζ. B. durch Verwendung von Selektivrufverfahren "bekannter Art, Sorge getragen ist. Die Wahrscheinlichkeit, daß mehrere Dienste gleichzeitig den Nachrichtenkanal "benutzen müssen, ist sehr gering. Zur Vermeidung von gegenseitigen Störungen wurden "bislang Synchronsysteme verwendet, mit denen die seitliche Staffelung der Zugriffzeiten zu dem Nachrichtenkanal für die einzelnen Dienste gewissermaßen vorprogrammiert sind. Solche Verfahren sind "beispielsweise "bekannt aus der DT-AS 2 106 309 und der DT-OS 1 591 206. Eine gegenseitige Störung der einzelnen Dienste ist bei Verwendung solcher Verfahren mit Sicherheit unterbunden,jedoch ist der Aufwand "beträchtlich, da sämtliche Dienste zentral synchronisiert werden müssen.Selection, ζ. By using selective calling "known type, care is taken. The probability that several services have to use the message channel "at the same time" is very small. To avoid mutual Interferences have "previously used synchronous systems, with which the lateral staggering of the access times to the message channel for the individual services, so to speak are preprogrammed. Such methods are known "for example" from DT-AS 2 106 309 and DT-OS 1 591 206. Mutual interference between the individual services is definitely prevented when using such methods, however the effort "is considerable, since all services have to be synchronized centrally.
Die vorliegende Erfindung geht von der Tatsache aus, daß "bei nicht voll ausgeschöpfter Belegung eines Nachrichtenkanals ein synchron arbeitendes Betriebsverfahren nicht unbedingt erforderlich ist und arbeitet daher asynchron. Es ist dadurch gekennzeichnet, daß in jeder Sendestation ein Zufallsgenerator vorgesehen ist, der für die betreffende Sendestation den Zeitablauf der Aussendung der Nachrichtenblöcke bestimmt. Mithin ist die Frage der Wahrscheinlichkeit, daß zwei Sendestationen gleichzeitig eine Nachricht absenden, eine rein statistische, wie sie sich nach den Regeln derThe present invention is based on the fact that "when a message channel is not fully occupied a synchronously working operating method is not necessarily is required and therefore works asynchronously. It is characterized in that a random number generator is used in each transmitting station is provided, which determines the timing of the transmission of the message blocks for the relevant transmitting station. Hence, the question of the probability that two sending stations send a message at the same time is a purely statistical one, as determined by the rules of

Mathematik, bestimmt. Zur Sicherung kann vorgesehen werden, daß 3eder auszusendende Nachrichtenblock zweifach ausgesendet wird, wobei die Wiederholung zu einem Zeitpunkt erfolgt, dessen Abstand ebenfalls vom Zufallsgenerator gesteuert wird. Da es nicht in allen Fällen erforderlich ist, daß ein reiner Zufallsgenerator Anwendung findet, sieht eine Abänderung der Erfindung vor, daß statt dessen ein Pseudo-Zufallsgenerator eingesetzt wird. Bei digitaler Arbeitsweise kann ein solcher durch ein rückgekoppeltes Schieberegister realisiert sein. Dabei haben die Pseudo-Zufallsgeneratoren für die verschiedenen Sender zweckmäßigerweise gleiche maximale Längen. Auch kann vorgesehen sein, daß die Übertragungszeitpunkte für die verschiedenen Sender abhängig sind vom Auftreten eines "bestimm ten Bitmusters innerhalb der Pseudo-Zufallsfolge. Auch kann man den Pseudo-Zufallsgenerator durch die auszusendende Information beeinflussen. Weitere Vorteile ergeben sich dadurch, daß nach erfolgter Übertragung eines Nachrichtenblockes der entsprechende Sender für eine gewisse Zeit für weitere Übertragungen blockiert wird.Math, for sure. To secure it can be provided that the message block to be sent is sent out twice is, the repetition takes place at a point in time whose interval is also controlled by the random generator will. Since it is not necessary in all cases that a purely random generator is used, see a modification of the invention that a pseudo-random generator is used instead. With digital Such a mode of operation can be implemented by a feedback shift register. The pseudo-random generators have the same maximum lengths are expediently the same for the various transmitters. Also can be provided be that the transmission times for the various stations are dependent on the occurrence of a "certain th bit pattern within the pseudo-random sequence. You can also use the information to be sent to the pseudo-random generator influence. Further advantages result from the fact that after a message block has been transmitted the corresponding transmitter is blocked for further transmissions for a certain period of time.
