At a user equipment a conditional bandwidth renegotiation method is provided for managing bandwidth renegotiations when the user equipment is engaged in an IPTV session with an IPTV network and a chan-nel switch has been requested. When it is determined that the requested channel requires less bandwidth than the presently selected channel, a con-ditional bandwidth re-negotiation process is initiated wherein, upon having switched to the requested channel, a timer is started if, a timeout of the pending timer is recognised prior to another channel switch request, a band--width re-negotiation procedure is initiated, while no bandwidth re-negotia-tion is to be executed if another channel switch request is recognised prior to timeout of the pending timer

Cette invention concerne un procédé de renégociation de largeur de bande conditionnelle dans un équipement utilisateur, qui permet de gérer des renégociations lorsque ledit équipement utilisateur est engagé dans une session IPTV avec un réseau IPTV et qu'un changement de canal est exigé. Lorsqu'il apparaît que le canal requis nécessite une moindre largeur de bande que le canal sélectionné actuellement, un processus de renégociation de largeur de bande conditionnelle est lancé selon lequel, après commutation sur le canal requis, une minuterie est déclenchée. Si le temps de minutage s'achève avant qu'une autre demande de changement de canal n'intervienne, une procédure de renégociation de largeur de bande est lancée; aucun processus de renégociation de largeur de bande n'est mis en oeuvre si une demande de changement de canal ne survient pas avant achèvement du minutage en cours.
