Abstract

Des modes de réalisation de la présente demande concernent un procédé et un dispositif de communication à base de NF et un support de stockage, destinés à être utilisés pour réduire la complexité d'une procédure de traitement de service. Dans les modes de réalisation de la présente demande, un élément de réseau de stockage de réseau reçoit un premier message envoyé par un demandeur NF, le premier message comprenant des paramètres d'un service demandé par le demandeur NF et détermine, en fonction des paramètres, un fournisseur NF correspondant aux paramètres. Si le premier message comprend des premières informations d'indication, l'élément de réseau de stockage de réseau transporte, dans un second message, une première partie d'informations de description dans des informations de description du fournisseur NF, les premières informations d'indication étant utilisées pour indiquer à l'élément de réseau de stockage de réseau de renvoyer la première partie d'informations de description au demandeur NF. L'élément de réseau de stockage de réseau envoie le second message au demandeur NF. Étant donné que seule une première partie d'informations de description est renvoyée et que le volume de données renvoyé est petit, la complexité de transmission de données dans un processus de découverte de service d'un élément de réseau de stockage de réseau peut être réduite, la vitesse de traitement de service d'un demandeur NF peut être améliorée et la vitesse du processus de découverte de service peut être améliorée.
