A mobile communication device registers for data communication through a mobile communication network with a packet-based network. The device may or may not have a mobile device number, and registers using a fully-qualified-domain-name (FQDN) uniquely identifying the device in a domain-name-system (DNS) of the packet-based network. A packet-data-network gateway assigns a packet-based address for the device, and generates a request for registering the address with the FQDN in a DNS server. Alternatively, the device generates the packet-based address based on a received portion of the address, retrieves the FQDN from an identity module, and sends a DNS-Update message to the DNS server including the address and FQDN. Again alternatively, a DNS server receives an encrypted DNS update message including a FQDN and a packet-based address, and decrypts the message prior to registering the address and FQDN in a DNS database. |

1. A method comprising steps of:
generating, in a gateway connecting a mobile communication network to a packet-based network, respective first portions of packet-network addresses uniquely identifying respective first and second mobile devices connected to the mobile communication network for communication on the packet-based network, responsive to receiving respective requests from the first and second mobile devices; in response to the request message, determining, by the gateway, that a router address is currently assigned to the first mobile device and that no router address is currently assigned to the second mobile device;
upon determining that the router address is currently assigned to the first mobile device, retrieving the router address by the gateway; andupon determining that no router address is currently assigned to the second mobile device, assigning the router address to the second mobile device; and generating, by the gateway, respective second portions of the packet-network addresses indicating the retrieved router address for the first mobile device and the assigned router address for the second mobile device; transmitting each of the first portion and the second portion of the respective packet-network addresses to the respective first and second mobile devices from the gateway; transmitting, from the gateway to an authentication server of the mobile communication network, a request message including the first portion and the second portion of the packet-network address of the second mobile device and a fully qualified domain name (FQDN) uniquely identifying the second mobile device in a domain name system (DNS) of the packet-based network; and transmitting, from the authentication server to a DNS server of the packet-based network, a DNS update message responsive to the request message from the second mobile device, the DNS update message including the packet-network address and the FQDN for the second mobile device. |
