Abstract

L'invention concerne un procédé destiné à assurer une connectivité sans fil améliorée pour des dispositifs sans fil fonctionnant dans un environnement hétérogène à technologies d'accès radio multiples (multi-RAT) pouvant consister à recevoir, sur un dispositif de réseau, des informations indiquant une ou plusieurs technologies d'accès radio détectées par un équipement utilisateur (UE) à des positions correspondantes auxquelles les informations reçues sont reçues en association avec une procédure à base de protocole d'ouverture de session (SIP, Session Initiation Protocol), et faire en sorte que les informations reçues soient fournies à une fonction de découverte et de sélection de réseau d'accès (ANDSF, Access Network Discovery and Selection Function). L'invention concerne également un appareil et un produit de programme informatique.
