Patent ID: 8832433

Claim:
A method comprising steps of: generating, in a gateway connecting a mobile communication network to a packet-based network: a first portion of a packet-network address for uniquely identifying a mobile device connected to the mobile communication network for communication on the packet-based network; and a second portion of the packet-network address for uniquely identifying the mobile device connected to the mobile communication network for communication on the packet-based network, wherein the second portion of the packet-network address is based on profile information associated with the mobile device, the profile information including at least one of subscription information of the mobile device and a type of the mobile device, wherein the first and second portions are combined to form the packet-network address; transmitting the generated first portion of the packet-network address and the generated second portion of the packet-network address to the mobile device; transmitting, from the gateway, a request message including the first portion and the second portion of the packet-network address and a fully qualified domain name (FQDN) uniquely identifying the mobile device in a domain name system (DNS) of the packet-based network, to an authentication server of the mobile communication network; and sending, from the authentication server to a DNS server of the packet-based network, a DNS update message including the packet-network address and the FQDN, whereby the mobile device is able to be identified for data communication using the first portion and the second portion of the packet-network address.
