  • Patent number: 11191014
    Abstract: There is described therein a method of roaming between 5G networks operator for selecting a network operator in a visited country when a mobile network user exits an area covered by a home network operator to enter the visited country covered by a plurality of visited network operators. This method of roaming is based on the concordance between the VNF supported by the visited country network and the network profile of the user. The network profile of the user embeds both the functions commonly chained in his home network to deploy the services corresponding to his usage and the functions required in the visited country network to perform the services desired by the user. Therefore, by matching this profile with VNF capabilities deployed by a network the invention allows a better user satisfaction in roaming situations providing them with the most suitable network.
