Abstract

La présente invention concerne un équipement utilisateur (100), un nœud de réseau central (106), un nœud de réseau radio (104) et des procédés à l'intérieur de ceux-ci, pour traiter des mesures de couche d'application par l'équipement utilisateur dans un réseau de communication. Le nœud de réseau central obtient (4:2) des informations en ce qui concerne les capacités de mesure de l'équipement utilisateur. Si les informations obtenues indiquent que l'équipement utilisateur supporte des mesures de couche d'application, le nœud de réseau central transmet (4:3), à l'équipement utilisateur, une demande de telles mesures de couche d'application. Ainsi, la signalisation associée à la demande de mesures de couche d'application peut être rendue plus efficace en transmettant la demande seulement lorsque l'équipement utilisateur supporte des mesures de couche d'application et non lorsque l'équipement utilisateur ne supporte pas des mesures de couche d'application, selon l'indication des informations de capacité de mesure. De cette manière, des ressources de réseau peuvent être sauvegardées sans les consommer en vain.
