  • TSC dispatches a service request either internally of the TSC or to an external device (step 728); • TSC responds with data services that may take the condition data into account (step 730);
  • TSC forwards the audio call or data received from the mobile unit (step 732).
  • TSC logs administrative data, service request data, and transaction information, then records or transmits billing information (step 734).
  • the TSC Upon termination of the call the TSC resets the communication channel and waits for a new audio call path to be established by another mobile device.

Abstract

L'invention concerne des procédés et des dispositifs permettant la réception et le décodage de données envoyées depuis une unité mobile (36) via un canal de trafic audio, et de fournir des services en réponse à ces données. Ces procédés et des dispositifs font appel à un contrôleur de services de transport (TSC (10): transport services controller) qui est connecté avec une voie de communication audio d'un réseau de communication ce qui lui permet d'intercepter et de recevoir les signaux audio d'une communication audio, d'extraire les données de ces signaux audio, et de distribuer des informations et d'envoyer des demandes de services en réponse à ces données. Le TSC (10) peut être connecté avec des sous-systèmes de signalisation ou avec l'autres ressources de commande réseau du réseau de communication, de manière à pouvoir commander et faciliter le fonctionnement des équipements du réseau de communication tels que les routeurs, les systèmes interactifs de réponse vocale IVR (416) les autocommutateurs privés PBX (410), et les équipements des centres publics gérant les appels d'urgence PSAP (326): (public safety answering point). Le TSC (10) peut également envoyer les données reçues à un destinateur de données par exemple par l'intermédiaire d'un réseau de communication de données spécialisé ou par Internet.
