Abstract: A roaming telephone user in a visited network dialing a long-distance number is transferred to a substitute telephone number which is local to that network and belongs to a service center. Typically, the visited network contacts the user's home network for permission to complete the long-distance call. When that happens, the home network obtains the substitute number from a database on a telephone number server, based upon the location of the visited network, and responds to the visited network, instructing it to forward the user's call to the substitute telephone number. When the service center receives the roaming user's telephone call, it contacts the telephone number server and obtains the original long-distance number, which is stored in the database in association with the substitute telephone number. The service center is then able to route the roaming users call efficiently and cost-effectively by making use of its base of service providers.

Abstract: A manner of extending a home network to a mobile device. An FA (foreign agent) in the mobile device registers with an HA (home agent) in the home network, preferable exchanging static UIDs (unique identifiers) and certificates. The HA creates an address for the FA and maintains a registration table listing all registered FAs. The FA registration is in most cases performed while the FA is operating non-remotely and directly connected to a component of the home network. The HA registers with an SG (signaling gateway) in a secure manner and awaits a request for access to the home network. After registration with the SG, the HA initiates a heartbeat message that is acknowledged by the SG. When an FA access request is received from the SG, the HA determines whether the FA is registered with the HA and any applicable access limitations prior to granting or rejecting access.
