Title
(EN) HOLDING PARTY CALL BACK SUBSCRIBER FEATURE
(FR) CARACTERISTIQUE ABONNE DE RAPPEL D'UN CORRESPONDANT EN ATTENTE
Abstract
(EN)
A first subscriber (30a) activates a hold call back subscriber feature in response to a second subscriber (30b) placing the first subscriber on call hold. After the activation, the first subscriber goes onhook. When the second subscriber later wishes to take the first subscriber off of call hold, a first end office (20a) serving the first subscriber recognizes the second subscriber's action and accordingly alerts the first subscriber back. Upon answering the ring back, a call connection is re-established between the first subscriber and the second subscriber. A connection-less signal is communicated between the first end office and a second end office (20b) serving the second subscriber to queue, monitor, and inform the second subscriber's action. Upon receiving a connection-less signal from the second office indicating that the second subscriber wishes to take the first subscriber off of call hold, the first end office originates another call setup request towards the second subscriber.
(FR)
Un premier abonné (30a) active une caractéristique abonné de rappel en attente en réponse au fait qu'un second abonné (30b) place l'appel dudit premier abonné en attente. A la suite de cette activation, le premier abonné raccroche. Lorsque le second abonné désire ultérieurement sortir le premier abonné de son état d'attente, un premier central local (20a) desservant le premier abonné reconnaît l'action du second abonné et avertit en conséquence le premier abonné en le rappelant. Lorsque le premier abonné répond à ce rappel, la communication est rétablie entre ce premier abonné et le second abonné. Un signal sans connexion est transmis entre le premier central local et un second central local (20b) desservant le second abonné dans le but de mettre en file d'attente, de contrôler et de faire passer des informations relatives à l'action du second abonné. Lorsqu'il reçoit un signal sans connexion du second central indiquant que le second abonné désire sortir le premier abonné de son état d'attente, le premier central local émet une autre demande d'établissement de communication à destination du second abonné.
