    Abstract: Providing for inter-system idle mobility management for independent mobil e networks is described herein. By way of example, registration of multiple mobile IP (MIP) addresses to a mobile device can be utilized to facilitate i nter-system device tracking. An Internet Protocol (IP) home agent that serve s the mobile device can associate the MIPs with a home IP address of the mob ile device. When communication is received for the home address, device pagi ng can be initiated by utilizing at least a plurality of the MIPs bound to t he home address. A mobile device response can provide a current active netwo rk address, and the received communication can be delivered via such active network address. As disclosed herein, the mobile device can switch attachmen t among the networks without signaling such networks, based on the multiple address bindings. Accordingly, significant power reduction can be afforded t o mobile devices in idle mode.

    Abstract: Methods and apparatus for routing messages between an end node and an access node via another access node are described. Physical layer identification information is used when identifying a remote, e.g., adjacent, access node as a message destination. Thus, when a connection identifier based on one or more physical layer identifiers is available to a wireless terminal, e.g., from one or more downlink signals received from a destination access node, the wireless terminal can use the connection identifier corresponding to the destination node to route a message via an access node with which it has an established uplink connection. Such connection identifier information can be used even when other addressing information, e.g., network layer address information, associated with the destination access node, may not be available to the wireless terminal.

    Abstract: Methods and apparatus for storing, manipulating, retrieving, and forwarding state, e.g., context and other information, used to support communications sessions with one or more end nodes, e.g., mobile devices, are described. Various features are directed to a end node controlling the transfer of state from a first access node to a second access node during a handoff operation thereby eliminating any need for state transfer messages to be transmitted between the second access node and the first access node during handoff or the use of a core network node to support state transfer. As part of a handoff state information is obtained by an end node from the current access node in encrypted form and then communicated to the new access node to which the handoff operation is to be completed. The new access node, e.g., base station decrypts the state information and then uses it to support communications with the end node. While the information is communicated to and from the end node over wireless links, since it is encrypted by the first access node it is secure and can be trusted by the receiving, e.g., target, access node.

    Abstract: Systems and methodologies are described that facilitate inter-system handover in a wireless communication system. Various aspects described herein provide for handover techniques that enable a target system to be prepared by a mobile device via a source system in order to minimize specific changes required to source system and/or target system. Techniques are described herein in which the radio link of a source system can be utilized to tunnel signaling messages which are in a format understood by a destination node in a target system. Further, fast inter-access handover can be facilitated by establishing a simple generic transmission tunnel between respective network nodes in source and target systems that handle intra-system mobility and providing a Layer 2 (L2) tunneling mechanism over the radio interface of each involved system technology.

    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.
