The present invention relates to a method and arrangements for controlling transmission of data bits in a bit transfer session for transmitting data information from an application server (2) to a client (1), said bit transfer session involving bit transfer over a wireless communications link by means of a transport protocol with a flow control mechanism. According to the present invention a radio resource managing unit (6) sends information regarding the bandwidth on the wireless link that the bit transfer session currently is allowed to use. This feedback information from the radio resource managing unit is used to set and update flow control parameters continuously throughout the session. Thereby optimization of the flow control parameters is facilitated, which makes it possible to enhance the end-user QoS and provide more efficient use of available radio resources.

La présente invention concerne un procédé et des dispositifs permettant de contrôler la transmission de bits de données dans une session de transfert de bits destinée à la transmission de données entre un serveur d'application (2) et un client (1), cette session de transfert de bits comprenant un transfert de bits sur une liaison de communication sans fil au moyen d'un protocole de transport avec un mécanisme de contrôle de flux. Selon la présente invention, une unité de gestion de ressources radio (6) transmet des informations concernant la bande passante sur la liaison sans fil que la session de transfert de bits est autorisée à utiliser. Ces informations rétroactives provenant de l'unité de gestion de ressources radio sont utilisées pour régler et pour actualiser en continu des paramètres de contrôle de flux durant la session. Cette caractéristique permet de faciliter l'optimisation des paramètres de contrôle de flux et, ainsi, d'augmenter la qualité du service pour les utilisateurs finaux et d'exploiter plus efficacement les ressources radio disponibles.
