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.
