  • Method and apparatus for switching access between mobile networks
    Patent number: 7460856
    Abstract: A method and apparatus for switching access between mobile networks for a mobile terminal comprising a first and a second radio device capable of communication with a first and a second mobile network, respectively. The second mobile network has priority over the first mobile network. A first connection is authorised and established between the firstradio device and the first mobile network. When it is detected that the mobile terminal moves into a coverage area of the second mobile network, a second connection is authorised and established between the second radio device and the second mobile network based on the authorising made for the first connection with the first mobile network. Both connections can then rely on the authorisation of the first connection.
