20110019614 | Enhanced Techniques For Using Core Based Nodes For State Transfer - 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 mobile 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. Other features of the invention are directed to the use of a core network node to store state information. State information stored in the core node can be accessed and used by access nodes in cases where a mobile node does not send a state transfer message during a handoff, e.g., because communication with the first access node is lost or because such messages are not supported. | 01-27-2011 |

20080316979 | Configuring a host device by way of MMP - The claimed subject matter relates to configuring a host device through utilization of MMP, which is a protocol that is based upon MIP but not associated with several deficiencies associated therewith. In particular, a wireless terminal can be configured to run MMP and send messages that conform to MMP over a wireless link. A base station can be configured to act as a DHCP server. The base station can provide configuration information to host device by way of DHCP. | 12-25-2008 |
20120087312 | METHOD AND APPARATUS FOR END NODE ASSISTED NEIGHBOR DISCOVERY - Methods and apparatus for using end nodes, e.g., wireless terminals, to discover base stations and communicate information about discovered access nodes, e.g., base stations, to other access nodes in a system are described. As the wireless terminal roams in the system and new access nodes are encountered, one or more physically adjacent access nodes will be informed of the presence of the new access node as a result of communications with the wireless terminal. A message indicating an access node's inability to route a message to another access node which is known to a wireless terminal may trigger the wireless terminal to begin the process of updating access node routing and neighbor information. | 04-12-2012 |

20090016300 | METHOD AND APPARATUS FOR FAST INTER-SYSTEM HANDOVER - 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. | 01-15-2009 |

20110286597 | HOME AGENT PROXIED MIPv6 ROUTE OPTIMIZATION MODE - A method apparatus, processor, and computer program product for wireless communication, including employing a communication interface to obtain a binding update message from a mobile node (MN). A data process is employed to analyze the binding update message for a network address of a corresponding node (CN). A communication interface is employed to initiate a long-life secure association between the CN and a network agent serving the MN if the binding update message contains the network address of the CN, wherein the long-life secure association enables the MN and CN to participate in a route optimized (RO) mobile communication session. The method may include employing a data processor to generate a binding cache entry for the network entity or a network component serving the network entity, wherein the binding cache entry includes a security key that facilitates a route optimized communication session with the network entity or the network component. | 11-24-2011 |
