Abstract

Des modes de réalisation de systèmes et de techniques d'identification de trous de couverture dans une technologie d'accès radio (RAT) sont décrits. Dans certains modes de réalisation, un appareil de gestion de réseau (NM) peut recevoir un premier rapport, comprenant une ou plusieurs mesures prises par un premier équipement utilisateur (UE), en réponse à un événement lié à un transfert intercellulaire du premier UE entre une première technologie d'accès radio (RAT) et une deuxième RAT différente de la première RAT. L'appareil NM peut recevoir un second rapport comprenant une ou plusieurs mesures prises par un second UE en réponse à un événement lié à un transfert intercellulaire du second UE entre une première RAT et une troisième RAT différente de la première RAT. L'appareil NM peut identifier un trou dans une zone de couverture de la première RAT sur la base, au moins en partie, des premier et second rapports. D'autres modes de réalisation peuvent être décrits et revendiqués.
