Title (EN) CALL BACK SERVICE FOR A REGULATORY RESTRICTIVE AREA
(FR) SERVICE DE RAPPEL POUR ZONE A SERVICE ADMINISTRATIVEMENT RESTREINT
Abstract:
(EN) A telecommunications system (10) receives a call back request through a separately maintained computer network, such as an X.25 based computer network (130), and initiates the actual call back toward the requesting subscriber using its own Signaling System No. 7 (SS7) telecommunications network (140). If the call back request fails, an X.25 packet containing an error code is transmitted back to the originating subscriber over the separately maintained computer network. An X.25$m(f)=$m(g) TCAP converter (110) is used as an interface card to allow X.25 packets to communicate freely with TCAP based telecommunications network.
(FR) Selon la présente invention, un système de télécommunications (10) qui a reçu une demande de rappel via un réseau informatique géré séparément, par exemple un réseau informatique X.25 (130), utilise son propre réseau de télécommunications (140) en protocole SS7 pour commande ensuite le rappel effectif de l'abonné demandeur. En cas d'échec de la demande de rappel, le système de télécommunications (10) renvoie à l'abonné demandeur, via le réseau informatique géré séparément, un paquet X.25 contenant un code d'erreur. Une passerelle X.25$m(f)=$m(g) TCAP (110), réalisée sous forme de carte d'interface, permet aux paquets X.25 de communiquer librement avec le réseau de télécommunications TCAP.
