Abstract

La présente invention concerne, dans des modes de réalisation, un procédé, un terminal utilisateur, un dispositif côté réseau et un système de communication sans fil pour le contrôle de mesure qui résolvent le problème venant du fait qu'aucun schéma de contrôle de mesure, dans l'état de la science, ne peut s'assurer que le terminal utilisateur réalise la mesure et obtienne le résultat de la mesure dans le temps, mais réduit également l'impact de la mesure sur la capacité du terminal utilisateur. Le procédé comprend les étapes suivantes : le terminal utilisateur reçoit les informations d'indication de mesure fournies par le côté réseau, puis le terminal utilisateur détermine qu'il doit réaliser une mesure et réalise la mesure en fonction de l'information d'indication de mesure. Les modes de réalisation s'assurent que le terminal utilisateur ne réalisera pas la mesure souvent, mais de manière pertinente, et réduira l'impact de la mesure sur la capacité du terminal utilisateur dans la plus large mesure.
