  • Patent number: 8228935
    Abstract: Systems, methodologies, and devices are described that enable communication devices, such as mobile devices, to efficiently connect and communicate with public data networks (PDNs) even if overlapping Internet protocol address spaces exist in the PDNs. The subject innovation can employ virtual home agents (v-HAs) that can respectively serve PDNs. To facilitate connection of a mobile device to a desired PDN, a message, including an identifier relating to the desired PDN, can be transmitted to a v-HA and it can be discovered whether that v-HA serves the desired PDN; if so, the v-HA transmits the message to a “home” home agent (h-HA) associated with the desired PDN; and if not, the v-HA can transmit a switch message indicating the correct v-HA to which the message should be sent. Concatenation of communication tunnels associated with the correct v-HA and h-HA facilitate efficient communication associated with the mobile device and desired PDN.

  • Publication number: 20090010206
    Abstract: Systems and methodologies are described that facilitate Mobile IP home agent (HA) discovery in a wireless communication system. Discovery of a HA for Mobile IP can be conducted as described herein for a mobile terminal located on a network wherein movement of the terminal is managed by a network-based mobility protocol. For example, various aspects described herein can be utilized for discovery of a HA located in a 3GPP network from 3GPP and/or non-3GPP access. Further, various aspects described herein can be utilized to discover a gateway acting as mobility anchor for a network mobility protocol utilized by the network. As additionally described herein, HA discovery can be conducted in connection with DNS query formation and communication, network attach and/or re-attach procedures, Neighbor Discovery signaling, and/or other procedures.
