Title
(EN) CALL COMPLETION SERVICE IN CASE OF CALLED PARTY UNAVAILABILITY
(FR) SERVICE DE TERMINAISON D'APPEL EN CAS DE NON DISPONIBILITÉ DU NUMÉRO DEMANDÉ
Abstract
(EN)
If an attempt by a first user (3) to contact another party (6) fails, a callback server (1) sets a flag (246). The callback server (1) monitors terminals that have such flags set (25) and is arranged to transmit an alert (27) to the calling party (3) when the called party (6) next becomes available. However, if at the time when the called party (6) becomes available, the calling party (3) is himself no longer available, being now switched off or busy, an additional flag (243) in the store (2), indicative of activity by the calling party (3), prevents a callback alert from being generated until the monitoring process (25) can obtain availability indications (263, 266) in respect of both parties (3, 69) simultaneously. Availability may be determined by factors such as available bandwidth or terminal capabilities. A callback may be initiated when a predetermined number of called parties become available to participate in a conference call.
(FR)
Si une tentative faite par un premier utilisateur (3) pour contacter un autre abonné (6) échoue, un serveur de rappel (1) place un drapeau (246). Le serveur de rappel (1) surveille les terminaux (25) assortis de tels drapeaux et est conçu pour transmettre un signal (27) au demandeur (3) lorsque l'abonné demandé (6) est de nouveau joignable. Toutefois, si au moment ou le numéro demandé (6) est de nouveau joignable, le demandeur (3) n'est lui même pas disponible, qu'il soit coupé ou occupé, un drapeau supplémentaire (243) dans le stock (2) signalant une activité du demandeur (3) empêche la génération d'un signal de rappel tant que le processus de surveillance (25) ne fournit pas des indications de disponibilité (263, 266) pour les deux parties (3, 69) simultanément. La disponibilité peut être déterminée par des facteurs tels que la largeur de bande disponible ou les capacités du terminal. Un rappel peut être lancé lorsqu'un nombre prédéterminé d'abonnés appelés devient disponible pour participer à une audio conférence.
