1. In a radio communication system having a mobile node operable to communicate data by way of a radio link with a fixed network, the mobile node associated with a home network provider that provides communication services for communication with the mobile node when the mobile node is positioned to communicate with a first portion of the fixed network, and the mobile node permitted mobility, selectably to be positioned to communicate with at least a second portion of the fixed network, communication services provided at the at least the second portion of the fixed network by at least one non-home network provider, an improvement of apparatus for facilitating determination of routing information by which to route the data communicated by the mobile node when positioned to communicate with any of the first and at least second portions of the fixed network, said apparatus comprising:

  • a registration request detector adapted to receive indications of a registration request generated by the mobile node, said registration request detector for detecting values of the registration request;

    at least a first table accessible at least responsive to detection by said registration request detector of the values of the registration request, said first table containing routing information indexed together with indicia associated with selected values of the registration request;

    a routing determiner adapted selectably to receive indications of selected routing information contained in said at least the first table, said routing determiner, responsive at least in part to the routing information, for determining routing by which the data is to be communicated by the mobile node, the routing determined by said routing determiner usable by the mobile node when positioned to communicate with the any of the first and at least second portions of the fixed network.
