Description
Verfahren und Anordnung zur Bestimmung der Wiederholungsgüte in Femmelde-, insbesondere Femsprechvermittlungseinrichtungen Die Erfindung betrifft ein Verfahren zur Bestimmung der Wiederholungsgüte durch Probebelegungen mittels Betriebsgütemeßeinrichtungen in Fernmeldevermittlungsanlagen, insbesondere Femsprechvermittlungsanlagep.Procedure and arrangement for determining the repetition quality in telecommunication, in particular telephone exchanges The invention relates to a method to determine the repetition quality by means of test occupations using operational quality measuring devices in telecommunications switching systems, in particular telecommunications switching systems p.
Bei der Betriebsgütemessung werden die verschieden vorkommenden Störungsfälle unterschiedlich stark bewertet im Hinblick auf den Eindruck, den der Teilnehmer von der Auswirkung der jeweiligen Störung bekommt. So werden zum Beispiel Gassenbesetztfälle weit geringer bewertet als zum Beispiel Doppelverbindungen oder Störgeräusche, die eine Unterhaltung unmöglich machen.The various malfunctions that occur are included in the operational quality measurement rated differently with regard to the impression made by the participants of the effects of the respective disturbance. For example, alley cases are occupied rated far lower than, for example, double connections or background noise, the make a conversation impossible.
Bisher wurde bei der Betriebsgütemessung der für die Teilnehmer besonders unangenehme Fall der wiederholt auftretenden, gleichen Störung bei mehreren, wiederholten Versuchen, eine bestimmte Verbindung zu bekommen, nicht berücksichtigt.Up to now, the one for the participants was special for the operational quality measurement unpleasant case of recurring, same disorder with several, repeated Trying to get a certain connection is not taken into account.
Aufgabe der Erfindung ist es, ein Verfahren zu schaffen, mit welchem das als Wiederholungsgüte bezeichnete Verhältnis von zustande gekommenen Verbindun-en zu fehlerhaften Verbindungen, die nacheinander bei wiederholten Versuchen, eine bestimmte Verbindung zu erzielen, auftreten, festgehalten werden kann.The object of the invention is to create a method with which the ratio of the connections that have been established, known as the repetition quality to faulty connections, which one after the other with repeated attempts to create a to achieve a certain connection, occur, can be held.
Erfindungsgemäß wird während der an sich bekannten Betriebsgütemessungen durch Probebelegun-"en 0 nach einer auftretenden Störung oder Hemmung dasselbe Verbindungsziel nochmals vom selben Eingang aus angesteuert und dabei registriert, wie viele Fehlverbindungen nacheinander auftreten, bis eine ordnungsgemäße Verbindung zustande kommt.According to the invention during the known quality of service measurements Probebelegun- "s 0 is the same after a malfunction occurs or inhibiting connection destination again driven by the same input and it registers how many faulty connections occur sequentially until a proper connection is made.
Bei den bekannten Betriebsgütemeßeinrichtungen stehen mehrere Eingänge, von denen aus die Probebelegungen vorgenommen werden, und mehrere Ausgänge als Verkehrsziele zur Verfügung. Nach einem entspechenden Programm wird zwischen den einzelnen Probebelegungen sowohl ein anderer Eingang als auch ein anderer anzuwählender Ausgang an die Betriebsgütemeßeinrichtung angeschlossen. Erfindungsgemäß wird beim Auftreten eines Fehlers dieser registriert und versucht, die Verbindung durch erneute Belegung des gleichen Eingangs und Anwahl des gleichen Ausgangs fehlerfrei herzustellen. Dieser Vorgang wiederholt sich so lange, bis eine einwandfreie Verbindung zustande gekommen ist. Durch geeignete Anzeigemittel kann das Verhältnis aus der Anzahl der gesamten Belegungen und den Fehlverbindun-en, die direkt aufeinander folgen, als Maß für die Wiederholungsgüte gebildet werden.The known operational quality measuring devices have several entrances, from which the test occupancies are made, and several exits as traffic destinations to disposal. According to a corresponding program, between the individual test occupancies both another input and another output to be selected to the operational quality measuring device connected. According to the invention, when an error occurs, it is registered and tries to re-establish the connection by reassigning the same input and dialing of the same output without errors. This process is repeated like this long until a perfect connection is established. By suitable display means can be the ratio of the number of total occupancies and the incorrect connections, which follow one another directly, are formed as a measure of the repetition quality.
Die Erfindung wird an Hand eines Blockschaltbildes in einem Beispiel näher erläutert. Die Betriebsgütemeßeinrichtung BME ist mit einem ZufallsgeneratorZG gekoppelt an den EingangE und den AusgangA des zu kontrollierenden übertragungsweges üW an-geschaltet, der aus mehreren Wahlstufen und anderen übertragungsmitteln bestehen kann. Führt die durch den Zufallsgenerator ZG hergestellte Verbindung zu einer Fehlverbindung, so wird dies in einer Auswerteeinrichtung Au festgestellt und in einer Registriereinrichtung Reg festgehalten. Die Auswerteeinrichtung veranlaßt den Zufallsgenerator ZG, die gleiche Verbindung nochmals herzustellen.The invention is illustrated using a block diagram in an example explained in more detail. The operational quality measuring device BME is equipped with a random generator ZG coupled to the input E and the output A of the transmission path to be controlled üW switched on, which consist of several elective levels and other means of transmission can. If the connection established by the random generator ZG leads to a faulty connection, this is determined in an evaluation device Au and in a registration device Reg held. The evaluation device causes the random generator ZG, the establish the same connection again.
