Title
(EN) TELECOMMUNICATION SYSTEMS WITH CALL DROP-OUT MESSAGING ACTIVATION
(FR) SYSTEMES DE TELECOMMUNICATION AVEC ACTIVATION DE MESSAGES D'INDICATION D'INTERRUPTION D'APPELS
Abstract
(EN)
When a telephone link is established between a mobile station, such as a mobile handset (1) for example over a satellite link (2, 3) through a telephone network (6) to a telephone (7), a messaging service is offered in the event of a call dropout, so that one party can record a message, which is retrieved by the other party after the dropout.
(FR)
Lors de l'établissement d'une liaison téléphonique entre une station mobile, telle qu'un téléphone mobile (1), par exemple, par une liaison satellite (2, 3) via un réseau téléphonique (6) à destination d'un téléphone (7), un service de messagerie est prévu dans le cas d'une interruption d'appels. Ce service permet à une des parties d'enregistrer un message qui est extrait par l'autre partie après l'interruption.
