A method and system for roaming between heterogeneous networks. The method involves authenticating a mobile communication device on a first network, providing the device with a single-use token that can be used to sign-on to a second network without requiring conventional re-authentication over the second network. The method and system allows a token or set of tokens to be sent to a mobile device over a secure and trusted channel. The token can then be sent over another network, operating over a different protocol to an authentication system where its contents are verified and authorization to access the new network is generated such that the token does not need to be processed by the new network. Hence the mobile device does not need to re-authenticate to the new network. |
