A method (400) for use in a cellular system with at least one controlling node (110), eNodeB, which controls user terminals, UEs (130), in a cell (120). According to the method, a UE can be in one of at least two different states (410), an idle state, a DRX state, and an "on duration" state. A UE (130) can receive at least a first (420) and a second (425) type of traffic from its eNodeB (110). If (415) the first type of traffic is received by a UE during an on duration period, the UE assumes the idle (DRX) state at the end of the on duration period, and if (430) the second type of traffic is received by the UE during an on duration period, the UE prolongs the current on duration period by a certain amount of time.

L'invention concerne un procédé (400) utilisé dans un système cellulaire possédant au moins un noeud de commande (110), eNoeuB, qui commande les terminaux utilisateur, EU (130), dans une cellule (120). Selon le procédé, l'EU peut se trouver dans au moins deux états différents (410), dans un état de veille, un état DRX et un état "sur la durée". Un EU (130) peut recevoir au moins un premier (420) et un deuxième (435) type de trafic de son eNoeudB (110). Si (415) le premier type de trafic est reçu par un EU pendant une certaine durée, l'EU adopte l'état de veille (DRX) à la find de la période "sur la durée" et si (430) le deuxième type de trafic est reçu par l'EU pendant une période "sur la durée", l'EU prolonge la période "sur la durée" en cours par un certain temps.
