Patent

CA 2284716

The invention relates to a method of playing an announcement to a call party in a telephone exchange during connection set-up. The invention is based on the idea of totally separating the detection of the need for an announcement from playing the announcement. In the invention, the need for the announcement is detected in a conventional manner at a given stage of call set-up (6.7). In the invention, however, the exchange does not play the announcement immediately, but delays playing it up to a later stage of call set-up or up to later event, if necessary (6.15). The announcement may be played, for example, not until collection of additional dialling is definitely terminated, the call is confirmed to be successful, the announcement is confirmed to be necessary/correct, and so on. As a consequence of the announcement, wrong and unnecessary annoucements and the failure of the call are thus avoided. The invention further relates to a telecommunication network exchange in which the method can be applied.

L'invention concerne un procédé de lecture d'une annonce destinée à un interlocuteur dans un central téléphonique, durant l'établissement d'une connexion. L'invention repose sur l'idée d'une séparation totale de la détection du besoin d'une annonce, de la lecture de l'annonce. Dans l'invention, le besoin d'une annonce est détecté d'une façon classique à une étape donnée de l'établissement d'un appel (6.7). Toutefois, dans cette invention, le central ne lit pas l'annonce immédiatement, mais retarde sa lecture jusqu'à une étape d'établissement d'appel ultérieure ou jusqu'à un événement ultérieur, si nécessaire (6.15). L'annonce peut, par exemple, être lue seulement après rassemblement définitif de toute composition de numéros supplémentaire, après confirmation que l'appel a réussi, après confirmation du caractère nécessaire/correct de l'annonce, etc. Ainsi, grâce à l'annonce, on évite les annonces fausses et inutiles, ainsi que l'échec de l'appel. L'invention concerne également un central d'un réseau de télécommunications où on peut appliquer ce procédé.
