A method for controlling temperature-related transmissions in radiocommunication systems. A mobile station includes a measuring device for determining operating temperature. When the measured temperature exceeds a predetermined threshold temperature, the mobile station can reduce its transmission rate, thereby reducing power dissipation within the device. The mobile station informs the system of the rate reduction, whereby the system can reallocate released resources, e.g., timeslots and/or spreading codes. The mobile station can also inform the user of the change in transmission rates and/or the temperature of the mobile station, whereupon the user can move to a better transmitting location. The mobile station can also take into account the transmit status of the current connection in determining when to reduce the transmission rate.

L'invention décrit un procédé de commande des transmissions liées à la température dans des systèmes de radiocommunications. Une station mobile comporte un dispositif de mesure permettant de déterminer la température de fonctionnement. Lorsque la température mesurée dépasse un seuil de température prédéterminé, la station mobile peut réduire son débit de transmissions, réduisant ainsi la perte d'énergie au sein du dispositif. La station mobile informe le système de la réduction de débit, permettant au système de réaffecter les ressources libérées, par exemple, les intervalles de temps et/ou les codes d'étalement. La station mobile peut également informer l'utilisateur du changement du débit des transmissions et/ou de température de cette station, ce qui permet à l'utilisateur de trouver un emplacement permettant une meilleure transmission. La station mobile peut encore prendre en considération l'état de transmission de la connexion courante, lorsqu'elle détermine quand réduire le débit des transmissions.
