Abstract
The application discloses methods and corresponding systems and network devices and/or nodes for enabling user equipment belonging to a home network to access data communication services in a visited network of a wireless communication system. By way of example, there is provided a method that comprises the step of obtaining at least one cryptographic token originating from a network node of the home network of the user equipment and cryptographically signed by a private key associated with the home network, wherein the at least one cryptographic token represents means for accessing data communication services via user data transport functions of the visited network. The method also comprises cryptographically signing the obtained and signed token by a private key associated with the user equipment to generate a double-signed token, and sending the double-signed token to a network node of the visited network, which validates the double-signed token for enabling the user equipment to access data communication services via the user data transport functions of the visited network.
