Enabling roaming to a visiting communication network of a wireless terminal belonging to a home communication network

Abstract

A method is disclosed performed by a system () of a home communication network () for enabling roaming to a visiting communication network () of a first wireless communication terminal () belonging to the home communication network. The method comprises receiving, from the visiting network (), an information of a connection attempt from the first terminal at the visiting network, detecting whether federated cloud roaming is allowed for the first terminal, and when federated cloud roaming is allowed for the first terminal, sending a request to the visiting network to deploy virtual network functions () reflecting a number of network functions () existing in the home network. The method further comprises communicating with the visiting network () in order to establish a virtual private network between the home network and the visiting network so that the virtual network functions () of the visiting network are connected to the network functions () of the home network, receiving information from the visiting network that the virtual network functions are deployed for handling the first terminal (), and in response to the received information, sending an acknowledgment to the visiting network () that the home network () acknowledges the connection attempt from the first terminal ().
