Provided is a device and method for scheduling uplink resources in a wireless communication system supporting VoIP . When its data rate is decreased, an MS notifies a BS of the rate decreased. When increasing its data rate, the MS requests resource allocation to the BS by transmitting a BR header or a CQICH codeword. Compared to the conventional ertPS in which the BS periodically allocates uplink resources to the MS irrespective of the state of the MS, the BS does not allocate uplink resources when the MS transitions form a talk- spurt period to a silence period. Therefore, resources consumption arising from unnecessary bandwidth allocation is reduced.

La présente invention concerne dispositif est un procédé permettant de programmer des ressources de liaison montant dans un système de communication sans fil prenant en charge le protocole VoIP. Lorsque son débit de données diminue, une station mobile (MS) notifie à une station de base (BS) cette diminution. Lorsque son débit de données augmente, la MS demande une allocation de ressources à la BS en émettant un en-tête BR ou un mot de code CQICH. Comparé à un ertPs classique dans lequel la BS attribue périodiquement des ressources de liaison montante à la MS quel que soit l'état de cette MS, la BS n'attribue pas de ressources de liaison montante lorsque les transitions de MS forment une période d'accélération des conversations en période de silence. Par conséquent, la consommation des ressources augmentant par une attribution de bande passante inutile en est réduite.
