Claim 14:
15. A user equipment configured for operation in a wireless communication system, the user equipment comprising processing circuitry, configured to:
obtain at least one cryptographic token originating from a network node of a home network of the user equipment and cryptographically signed by a private key associated with the home network, the least one cryptographic token being usable for accessing data communication services via user data transport functions of a visited network and representing at least one of a predetermined or maximum data consumption limit, and a price range limitation;
the user equipment being configured to cryptographically sign the received and signed token by a private key associated with the user equipment to generate a double-signed token; and
send the double-signed token to a network node of the visited network for enabling the user equipment to access data communication services via the user data transport functions of the visited network.
