Abstract

Des modes de réalisation de la présente divulgation concernent des dispositifs, des procédés, des appareils et des supports d'enregistrement lisibles par ordinateur de l'exigence de mesure pour l'économie d'énergie. Le procédé comprend, conformément à une détermination selon laquelle une DTX est activée par un second dispositif, la détermination d'une période de mesure relâchée associée à une mesure effectuée par le premier dispositif ; et la réalisation de la mesure sur la base de la période de mesure relâchée ou d'une période de mesure non relâchée. De cette manière, en introduisant la période de mesure relâchée, la précision de mesure requise peut être obtenue au niveau de l'équipement terminal même si l'économie d'énergie est activée au niveau du dispositif de réseau.
