A method as described by which an application executing in an application layer of a multi-layer communication protocol forming part of a general packet radio service (GPRS) session can signal for the setup and release of Temporary Block Flow (TBF) which will not be released during application execution in silent (inactive) periods. When applications such as voice, telnet or web browsing have specific traffic type data that have inactive periods between active periods are to be carried over GPRS, the session consists of multiple active periods. Current TBF release procedures lead to multiple TBF setups during such sessions. With the method described, a special type of TBF can be set up with special procedures for release of this TBF which greatly minimizes the need for multiple TBF setups during a session containing data transfers with inactive periods between active data transmissions.

La présente invention concerne un procédé par lequel une application, qui est en exécution dans une couche d'application d'un protocole de communication multicouche faisant partie d'une session de service général de radiocommunication à commutation par paquets (GPRS), peut signaler la configuration et la distribution de flux de blocs temporaires (TBF) qui ne sera pas distribué lors de l'exécution de l'application, dans des périodes silencieuses (inactives). Lorsque des applications, telles que vocales, Telnet ou l'exploration sur le Web, présentent des données à type de trafic spécifique, qui ont des périodes inactives entre des périodes actives et doivent être transportées sur GPRS, la session consiste en plusieurs périodes actives. Des opérations de distribution de TBF courantes conduisent à de multiples configurations de TBF, lors de telles sessions. Au moyen du procédé selon cette invention, un type spécial de TBF peut être configuré avec des opérations spéciales pour la distribution de ce TBF, qui minimisent grandement le besoin de recourir à de multiples configurations de TBF, lors d'une session contenant des transferts de données avec des périodes inactives entre des transmissions de données actives.
