Method and apparatus for roaming between communications networks

摘要

There is provided a method of managing roaming of a Mobile Node in a Visited network. The Mobile Node is associated with a Home network. In the Visited network, a server selects a Gateway node for use by the Mobile Node based on selection criteria. The Gateway node is disposed between the Home network and the Visited network. The server then sends a message to an access node in the Visited network to which the Mobile Node is attached, the message identifying the selected Gateway node. This instructs the Mobile Node to communicate with its Home network via the selected Gateway Node.
